The Sprintbooster is hands down the best mod you could ever buy for your Drive By Wire SRT-8!!!

http://www.performanceautowerks.com/catalog/images/Sprintbooster42.jpg


This little device is impressive! One of my biggest gripes with the Grand Cherokee SRT-8 or any SRT-8 vehicle, hell even any drive by wire vehicle has always been the delay in throttle response. This device now solves that problem for good!:)

Benefits -

Eliminate that ridiculous head bobbing throttle delay for good!

Sprintbooster reduces the delay of DBW throttle response, providing instant acceleration!

1 minute installation!


Here is a Racepak data graph showing the before and after differences -

^ sounds interesting. How does it work ? And how do you install ?

^ sounds interesting. How does it work ? And how do you install ?

It is a piece of electronics wizadry that I fully cannot explain. As I am told it uses fuzzy logic and microprocessors to transfer data and store energy, custom vehicle specific programming is then used to eliminate the DBW delay. Basically a very technical e-prom with custom tuned software to change the “MAP” or curve of the throttle

The device simply plugs into the throttle pedal, simply unplug the OEM harness and plug this unit inline.

I was skeptical at first but then totally amazed when I first tried it out, one of the simplest and best mods you could do in my opinion.

how does it store energy? :rolleyes:

seems cool but its alot of money

I know it is a few bucks for sure, but I can guarantee that it is worth every penny!

If it fails, what happens to your throttle?
Just curious to know what it's fail safe is?

Is it compatible with a predator tune? Or a cmr tune?

Good question. We have not had any failures yet but I am told by the manufacturer that it's circutry is designed as a piggyback type device, so if the unit fails nothign is interrupted and you will be able to drive just fine.

I just sold through my first 5 SRT-8 units I received but I have more arriving tomorrow, stop by and we can test it out if you like.

Yes, it is compatible with any tuning device or software.

I might just do that.

I'm assuming this works for the LX vehicles as well then?

If you can find one that will work on an 07 MB SL550 I can guarantee you a sale

I'm assuming this works for the LX vehicles as well then?

Yes it does, different part numbers and slightly different programming but we have them in stock as well.

In stock too, they work incredibly well on the MB cars and trucks!

I have heard of the mercedes guys using these but I have not seen or felt one first hand. I would be interested to hear some feedback from someone on here who is close to you and can test one out.

No problem keep me updated

So...I am close enough to Werks that I had to try out the Sprint Booster. Plus, Greg said he would install it so I could get a test drive in before purchasing. Can't pass that up, right?

I will say that I noticed enough of a difference right away that I had to buy it. But it was on the trip home that I really started to realize the difference it makes. Not only when punching the gas pedal to the floor, but in normal driving as well. That hesitation is gone when you get back on the gas in a corner, or just roll on to make an easy pass. Pay attention when pulling from a light with a car in front of you...it just goes. Of course, the best part is when you flat nail it!

Enough said; I bought one! Pricey, perhaps...but a noticeable improvement. Great mod!

I definately makes it easier to drive for the wifey :)

Niiiice glad I bought one. Hey Greg you should talk to sprint booster about making one for the new '09 CTS-V...They could really use one

They most likely will. They have a lot of new applications in the works.

how about a group buy?

how about a group buy?

I would love to but the pricing structure is being held very solid by the manufacturer. If they see anyone advertising a lower price than their fixed $329.00 they will revoke their reseller privelage immediately.

I definately makes it easier to drive for the wifey :)

She doesn't drive it but gets jerked into the seat when she is putting on make up.

seem like a great mod! I agree too on the price.just a bit high:( I'll wait for more people to try it & report first....

My throttle likes to stick open during partial throttle under transition from vacuum to boost.

Nothing like taking your foot off the pedal only to just keep on gettin it. :eek:

Wonder if this would fix that.

Now that's funny! You will have to adjust your driving a bit to avoid the lipstick across the cheek syndrome...

After three days of driving, I really do like this mod more and more. The throttle lag was annoying, but I adjusted and got used to it like everyone else. The thing is, you'll really notice how bad it was once it is gone. Throttle modulation is up to me now, not the computer. The biggest difference is in normal, part-throttle driving. Like I said before, I was suprised a few times early on when I took off from a light and had to lift to avoid rear-ending the car in front of me. Don't get me wrong, the difference is still obvious punching it from a dig! You tell it to go and it will.

Now, if only Vortech would send me my supercharger...

Feel free to order one, if you don't like it you can return it for a full refund! We are pretty confident that you will like it!

Good review JW, we'll get on Vortech to deliver your baby soon :)

Hey Greg, I got the sprinter and there seems to be nowhere to hook it up to the pedal, maybe you can point it out. The only part that I thought it would clip into is the harness clip i circled in red but that clip size is about half the size of the sprinter slot....

http://img12.imageshack.us/img12/9454/img0152m.jpg (http://img12.imageshack.us/my.php?image=img0152m.jpg)

How does this work with a predator?? How much increase would one get with both the predator and the booster???? Also, how easy is it to install???

Thanks

This module just accelerates the tip in speed of the pedal.
You could do the same thing with the CMR tune.

So you're saying that the CMR tunes have this ?

Yes, the same (SOP feeling) and manipulating the of the PCM receiveing the accelerator pedal signal..

Basically the module increases the voltage and tip in speed of the signal input to the PCM (kinda like the "fake CMR tuners" where doing in the beginning )just increasing the tip in speed to give the SOP feeling of a better faster more powerful tune, but not changing the PCM calibration.

If you have the Predator a custom CMR tune if you want it manipulated will give you the same "feeling" as this module but no real gain.

^how would you go about doing that in a cmr/diablo tune ? I know the sprint booster isnt' increasing hp/tq. Just driveability. I hope nobody expects it to give you 5/10/15 hp.

I wasn't gonna give that info out, noticed I said I bought one for the MB not the Jeep:D I have no throttle lag on my tune. It's all about what tuner you use and either your getting a One Size Fits all tune or a REAL CMR tune;) You would be amazed at the HUNDREDS of tables that you could be logging in order to get a good CMR tune, heck I had to go into Diablos Dataviewer section under NOT SO COMMONLY USED parameters to get the ones my tuner wanted.

So basically you guys are saying that if you have a "proper" CMR tune than these adjustments should have been made and there would be no benefit from a "sprintbooster' ?

I'm not saying that and neither is Jeff. What were getting at is that knowledge is power:D Really you cannot blame CMR tuners because they are the ones dictating what you get, now turn the table around and let the consumer custom order a list of what he/she wants in a tune then you get what you want and get what you pay for. I think the common customer of a CMR tuner has no idea of what they are capable of getting most just want to go faster there are VE tables to monitor and all sorts of things not only to make you run faster but to make daily driving more enjoyable as the majority of use drive our jeeps in the 0-40mph range on a daily basis. What Jeff is saying if you complain to your CMR tuner that your having to really put your foot into the gas pedal to get a response the tuner should be able to fix that to your satisfaction. Some may be just fine with it and do not want to barely hit the gas pedal and mount the car in front of them-LOL

I chose it for the MB cause a tune for the MB is way too expensive and this was really the only thing that was bothering my buddy who owns the MB so the sprintbooster in this case is great.

^ I got ya. Sounds like something that would work great for someone that wants increased driveability yet doesnt want to hassle with warranty/tune issues and/or overpiced tunes.

Yeah its a great little device I know alot of MB and BMW owners love theirs considering paying ALOT of $$$ for something similar

Yep, and for 300 dollars you can get a Diablo handheld and still get more value for the dollar.

But than you have the hassle of uploading the original everytime to go to the dealer incase something happens and it becomes a warranty issue. And if you wanted just the throttle adjusment you'd end up spending money ontop of the $300 for a custom tune since the only ones coming with the predator are the cans

Yep, and for 300 dollars you can get a Diablo handheld and still get more value for the dollar.

I doubt anyone will debate that point, but not everybody has the time or means for a $300 Diablo PLUS $250-$500 for a CMR tune. For folks like me who have a few mods and are annoyed by this perticular driving issue, a fix that you can do at home for $300 is a nice option. I won't pretend to be a Diablo expert; I won't even try to tune my ride...but I can plug and play. The improvement in driveability with my canned CAI tune is obvious.

Yes, I could have done a CMR tune at this point...but am trying to hold off until this round of mods is done. I had the GC tuned at another local shop, and had to go back to the CAI tune due to driveability isues. Right now, I don't have the time or money to tune this thing over and over. If you have the funds and access, by all means, go for the Diablo/CMR...not everybody fits into that category. It's just another option that seems to work well.

Okay, thanks. I did get the pictures and I forwarded them to the guys at SB to take a look at. They are checking to see if they have another device they could program up that matches the plug that you have.

Sorry about this, I was not aware that the 08+ Jeeps use a different throttle pedal connector.

Hey Combatmedic, what year is your jeep ? I dont think these 'sprints' fit '08+ years


Mine is an '06. You just had to get one of the fancy new ones, huh? I'm amazed at how many seemingly innocuous Jeep parts get changed year to year. I crunched the bottom of my front end on some ice (playing snowplow) and wanted to swap to the later model front end. Between the dealer and the body shop, it took them forever to figure out the part numbers for the swap. One shop told me that there are no differences from year to year, and another said the swap couldn't be done.

I imagine with all of the electronic and mechanical gear on our rides, we'll be finding lots of changes/parts confilcts as we go. I hope Werks can get the right part for you!

Sprintbooster just got back to me and they have a new part number for the 08+ SRT-8s. I ordered some of those in and will ship Razorecko's out to you as soon as I receive the new ones.

For all future orders please put the year of your SRT-8 in the comments section when placing your order online.

Alright guys this is one of those upgrades that I believe you have to see or feel to believe. Everything I have seen and read about this product is true. This in mine opinion should have been how the Jeep should have left the factory. The Jeep just moves like your right leg is apart of the throttle from launch and part throttle, the responsiveness and power delivery reminds me of a 5 or 6 speed not a slushbox. I was on the fence thinking the CMR tune would be able to fully tune out the delay but after speaking with some other SRT8 owners they told me the delay would never be 100% removed especially from the launch...once again this is second hand information (not sure if anyone with a CMR tune has installed this and if they see a difference?). To me this is a MUST for the Jeep I would highly recommend this to any speed junkie that want to fully enjoy the SRT8. Can't wait to get this on a road course! :D

Hey Greg & Dave - sorry for digging up an old thread - just a few quick technical questions please:

1. Can you explain why the steady state response, with the sprint booster installed, (pink data line in the top plot) dies off at the end? (maybe just took your foot off the pedal?)

2. From what i remember about controls, this plot resembles an underdamped 2nd order response - so is your product based on some type of PID control structure? did you guys then just bump up the proportional gain? (it looks like with the sprint booster installed the transient response has slightly more overshoot)

3. If the above is true, have you guys tried to play with the gains to achieve a critically damped response (i think adding some derivitive gain for overshoot and some integral for steady state error (probably not necessary - so just PD control))?

4. Again, if 2. is true, is there someway we could adjust the control gains ourselves (on our own liability of course?) or request your company to?

5. This product should work with any size ported throttle body?

Thanks

That is a bit over my head unfortunately. I will forward this to the engineer who actually does the work on these devices and see what he has to say about it.

^ hey thanks :) - totally cool - i could be mistaken, but I think the trend of the top plots look familiar....

Different model number for the 06-07 and the 08's (http://www.sprintboosterusa.com/c-113-at.aspx)

You guys say the CMR tune does the same thing, does anyone know if the the DCX tune (http://www.dcxdepot.com/dPG-Custom-Tune/c139/p804/dPG-Custom-Tune-for-Hemi/product_info.html?osCsid=b5f6efcd92af9349e8254e810 639a830) does too? or if, at least, it improves throttle response?

Yes there is a different part for the 2006 SRT-8s versus the 2007-2009 models. The CMR tuning can improve throttle response but does not do the same thing as the sprintbooster.

Agreed. I think what is making some hesitant is what Paul (YoungMedic23) went through and I believe one other, something to do with a loose connection or something have you guys talked to the MNF about quailty or that issue.

That is a bit over my head unfortunately. I will forward this to the engineer who actually does the work on these devices and see what he has to say about it.

Lower the price and the will sell a lot more. It look cheep to make.

Still too much $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$.

Yes I Agree....but Bought One & Dont Regret It....it Took Me 2 Days To Figure Out If It Was Worth It(i Live On A Island) & It Sure Is.."AMAZING" Is The Word!sotp Feeling Is Night & Day Diffrence!

Just ordered one Dave. Look forward to the additional pop.

If it was Cheeper I would get it and if it work that good I would show it off to the guy in my SRT 8 Jeep club and they would pick some up too.

Just ordered one Dave. Look forward to the additional pop.

I'd be down for a group buy man.

Dam* you guys. I told myself (and wife) that when I got the Jeep I was going to leave it stock except for some cosmetic changes. I have the Grand National in the garage to take care of anything the Jeep can't handle. Well first I got a Volant and now I'm going to have to get one of these things.

Hey Dave, if I drive down to see your shop will you do the install?

Since Dave is impossible to reach or takes days to respond I have corresponded with Sprintbooster too see if they will work up a group buy, heck they actually sell them 4 cents cheaper than Dave does I was under the impression resalers sold them cheaper???

I told myself I was leaving my Jeep stock too....and I've failed miserably :D
Install is very simple though if you wanted to avoid the drive to Plainfield.

I hear ya DC. Hopefully Centraltexhemi will be able to get us a group buy so I can save a few bucks .... and put it toward a billet catch can.:D

And I should probably avoid seeing Dave's shop or I could get myself in real trouble.

OK, got an email from Dave at Werks. Problem resolved.

Thanks Dave!

Since Dave is impossible to reach or takes days to respond I have corresponded with Sprintbooster too see if they will work up a group buy, heck they actually sell them 4 cents cheaper than Dave does I was under the impression resalers sold them cheaper???

Resalers have a minimum price they can charge for a unit, they purchase it at a discounted price.

I received an email from Chris Faulkner an employee with Sprintbooster who is all for a group buy on these but since I am not a vendor I dont see how this will work so this is where Performance Autowerks can step in and coordinate with Chris on a group buy.

You just read my mind Wade. I was just thinking about this. If he can do a group by I will drive the 45 minutes from the CHI-TWN to go pick it up.

I'd be interested in one also.

Guys I'm at the SEMA show in Vegas and Sprint Booster has an exhibit here. I'll track them down today and pursue this group buy a little further.

I installed my SB on Tuesday night and it works great but I’m slightly disappointed in the actual quality of the little thing. The outer shell is basically two pieces of plastic joined together. On the one I got from Dave the two pieces weren’t joined together evenly and were offset a bit. At first this offset wouldn’t allow the unit to slide into my rigs throttle piece. Made me think it was the wrong part. So I had to tweak the thing a little to get the halves to line up and then it went in. Going to talk with SB about that today as well.

Incidentally SB has won an award here for one of the best new products.

If you order the SB from Autowerks, don't order the Transmission Filter kit in the same order. They don't stock it, and it's slowing down my ship date... It should be delivered already. Last email I got said it will ship on Friday. I ordered it last Thursday :(

Really looking forward to trying the new product though. Plus you will get my, and Wade's(centraltexhemi), and maybe even spencer's opinions on it. I'll pass it around to let them all try and see what they think.

If it works like they say, I'll prolly get my friend Chuck one for his Chally for Christmas.

Just ordered up my Sprint Booster, so we will see what difference I get with it at the track on SAT. Thanks Dave for taking my order!

What I learned from SB is that they are very protective of their dealers and wouldn't offer a group buy direct. A couple of options were mentioned when I told them about our groups plans....either become a dealer...don't have all the specifics but it involves making an initial purchase of 10 units at wholesale. Apparently more info for this is on their web site. The other option and this might be one that works is to go on their web site use the menus to locate a dealer and to work with that dealer on a group buy. This is of course if perf auto werks doesn't step up. Since I got pretty good service from Dave at werks I'd hope he'd come through.

Thanks for the update LoudPedal! Dave is the man I purchased my Sprint Booster today and it will be here tomorrow. Can't wait to get it in on my BEAST:D I am sure he will take care of you guys if there is enough interested buyers to get in on a Group Buy. Thanks Dave!

You're welcome man...glad Dave is get'n er done for you. He's a good dude. Enjoy that mod. It is pretty cool I must say. Drove the beast the 15 miles to work today and could really tell the difference. No hesitation now when hit'n the gas and the one WOT run I managed in autostick was seamless. Better launch and it seemed like the 1-2-3 shifts were crisper. Man I love this rig.

Yeah just got it today and will install it after work. Hoping I will feel a difference!

UPDATE: Well I got a chance to go to the track yesterday and found out that the Sprint Booster did not really improve my 60 Fts or overall ET. I also got a chance to make one run with out it and my 60 ft and ET did not really change. So overall I agree that I can definitely feel a difference in how sensitive my Gas pedal is now and that I can feel in a difference in normal everyday driving and at WOT when launching. Also at first I thought I lost performance so I took it off but I installed it back on and you can definitely feel a difference guys in normal everyday driving like switching lanes and doing some WOT. So I guess I will keep it.

Thanks for the update. Agree on the everyday driving and WOT launch. Did you happen to measure your reaction time with/without the SB? Might be too small of a difference.

Pretty good average anyway. Didn't look like the booster added much there. I would've thought it would help RT. Oh well it sure smoothed out the response on mine.

"Werks" do they make them for a generation 4 viper?

Hey Blown7, speaking of snake oil, whatever happened to you tuner project, s/c project, SRT GC project. Are any of them still alive?

Wow, you guys are brutal!

We are still doing CMR tuning on the dyno only. No mail order stuff as it gets to be too much of pain in the butt.

The Supercharged GC went elsewhere, I am not sure of the status of it currently. When it left here we still had dyno/fuel system work to do and it was at 500whp, that is the last I heard.

I am still looking at purchasing my own GC SRT-8 but I need to pay off my 3500HD first.

Dave, Any news?

Dave, Any news?

So how is it?

Basically this product is like pressing the "sport" button in my friends M3... it just moves the WOT point in the pedal to about half so at half pedal you are WOT... so by the time you expect WOT (pedal to the floor) it has already been told be get there... good product just thought id edjumicate...
