Well fellas,

I had a couple great opportunities this week to get some more power out of the Jeep. My bro is going in for the Techco Power Lab 427 so I figured why not take his heads that are currently on his car. So now the Techco Jeep is getting the PPP Stage 2 heads, a new PPP Twin Screw 218/224 555/555 115LSA Camshaft, Kooks Long Tube Headers courtesy of BuilderBill, Magnaflow Exhaust, and Bwoody Lowering Springs! It will then go back to Techco for another tune and then off to the track!!!!! Man I can't wait to get her back!!!

Which track?

See you there ;)

I hope its successful. I'm getting so tired of waiting on a successful twin-screw Jeep... only somewhat proven PD out there so far is the harrop, and thats a custom application from RDP, not a S/C company.

Albuquerque National Dragway, come on down!:D

I am hoping the same thing too Winston...lets cross our fingers.

Damn Snehal!!!! Now when you get it back, get that beyotch detailed all perrrrrfect and post some GAWD DANG PICS!!!!!!!!!!!!!! :D

Sir Yes Sir!!!! LOL! So whats the story with the tranny, any decision yet buddy?

Dude. I'm just trying to save as much money as I possibly can. This was TOTALLY unexpected. HOWEVER. My other two options don't seem very promising. And with Eddie making such a kickass trans............well...........

I might be driving through Vegas when you are there, if we get a chance to meet for a few minutes that'd be sweet!

"Meet"??? For a "few minutes"?? Don't you mean "drink" for a "few hours"???!!! :D

LOL! Lets do it!

PM sent fool!!!! :)

Sounds like you're getting some good addons there and a cam for your blower. Going to keep it at the stock 5psi?

And on those blowers themselves, any idea when they're shipping them? Vendors were saying some time this week. Wanted to see if anyone here is taking the plunge.

I know they had quite a few sold, I am not sure who they were that bought. I can ask Carlos tomorrow when they are shipping.

Hell yea, that's gonna be sick. Can't wait for another ride, but this time I'm tacking a neck brace.

Why is the techco boost linear instead of instant? One of the selling points of a twin-screw blower is the instant boost capability, but every techco graph I have seen, you can tell the boost is linear like a centrifugal.

The boost is instant but you do get a boost rise as rpm increases, this is characteristic of a larger displacement supercharger that is porperly sized to the engine in which it is mounted.

A ‘linear’ boost curve like a centri blower has would be at zero at some point during WOT and then climb steadily with RPM. With the Techco, you will see instant boost at WOT at any RPM and see maybe a 1-2 psi rise with RPM.

For companies new to twins screw technology, I see how this assumption could have been made.

Was the 'jab' at PPP necessary? Only shows lack of professionalism on your part.

PS. No such word 'misassumption' :rolleyes:

He and I play back and forth. Its all in good fun.

Thank you for the correction.

I did not interpret it as "friendly".

Andy,

How much boost are you guys running on the stock block with the Whipple?

Please dont take this as a bash, but I am used to seeing twin-screws offer the same increase in tq as hp, but what I have seen so far with Techo systems is allot less tq than hp increase. This is the graph that confuses me. Im assuming 5psi and a stock srt8 challenger.

http://i182.photobucket.com/albums/x281/PPP-Tech/Dynos/techcochallenger.jpg

Typically, SRT8's make 350rwhp/350rwtq on DCX Depots Dyno, so they gained 96rwhp/74rwtq with 5psi resulting in 446rwhp/424rwtq. Our srt8 Charger with a Pro-Charger made 470rwhp/480rwtq with 5psi on that same dyno, so I am confused as to why the tq is so low with the Techco blower when Twin-screws typically are known for their awesome ability to produce tq. With the longer runners of the Techco, I expected tq to be over 500rwtq.

Again, I am not trying to bash and the info looks negative, I am just trying to understand why the tq is so low.

I thought I recalled seeing some other dyno runs on l x f o r u ms with techos with maybe a cai or exhaust only and tune with the type of characteristics you've asked about - high insta-torque and like 113-125 hp gain.

Purloined from the lx 4rums site:

These numbers are based off the 2008 SRT8 Superbee. Stock baseline was:
370 rwhp
368 rwtq

After Techco Reverse-Revolution twin screw supercharger installed it is now:
499 rwhp
469 rwtq

This is done right at about 6 lbs of boost, and yields a 129 rwhp gain!!

Here is the dyno graph showing the stock vs. Techco supercharger pulls:


I'd say that PPP questions are good ones, because I'd more expect below's performance than what is posted above, especially w/r/t torque. Most of the other pulls I've seen on the other site look like this one below. Maybe something to do with the tune, or some other factor? This thing below looks pretty strong.

Most people are just looking at the highest#s when there looking at dyno sheets, I know peak #s are important but not as important as the curves themselves. I have dynoed a ton of different type of Hemi vehicles and have seen lower dyno numbered vehicles beat up on these high peak numbered vehicles that have dynoed on the same day one right after another at the track leaving their owners pist and scratching their heads. I have literally seen Cars/Trucks that make 15 to 20 more peak HP get beat by the lower dyno numbered Cars/Trucks. The idea here is don't always fall for these higher #s they can be, not always, but very deceiving...

Those are good numbers, but they still look like a centrifugal blower and not a twin-screw. The tq should be just as high as the hp. Because it isnt, I asked if they were achieving full boost by 4600rpm where peak tq generally occurs. It was noted that full boost was not achieved instantly which is why the tq numbers are lower, but I still dont understand why the boost builds progressively unless it is just too big of a blower. In all fairness to Techco, I will ask these questions on another site since they can not respond here.
