AZ Speed asked me what I was doing to get more fuel to the Hemi for the supercharger which would also apply to those of us with strokers and turbos. They said we should be looking at the fuel pump w/ relay and fuel lines.
Hell, I never thought of this. They have a very valid point, if we are going to increase our horsepower by say 150++ with the mods we are doing, how are we going the feed the beast? Any thoughts while we wait patiently for our superchargers etc???

Adding in a high flow fuel pump is not a big deal but for 7,500k they should not be asking how we are going to deliver fuel. This is common sence and should be part of the kit, since we can not control line pressure through the PCM YET.

I just find it a bit funny its not included.

Agreed. I thought it was a complete kit with fuel and PCM upgrades.

Complete kit with fuel, yes, but we all know it won't include a cracked PCM.

They asked you that?, they should be the one supplying the correct fuel system and tuning.

What were they gonna do, send you down the road with a blower and a lean fuel condition? (KABOOM).

I would ask how quickly they process refunds...

They are using a piggy back system of some sort. This is what most of the confusion was about in the initial research to by this. We were pretty much guarnteed that the Piggyback would cure all problems found with the GS kit.

They are adding 8 larger injectors that will not flow much different with out tune of some sort or more line pressure. So like i said this should all be common sense when building this kit.

BILL, I hope this info is wrong, and you were talking to them about your stroker motor combined with their kit. In this case it would be up to you to solve your fueling issue.

Turbocharging any NA motors usually requires some sort of fuel modifications. Pushing 150+ more hp, I would think one would run at least a Walbro 255gph pump, or the Bosch +44, maybe even with -8an lines, fuel pressure regulator, return line and different fuel rails. A full fuel system isn't TOO much money, and is a good safety precaution. Most turbo kits for anything out there usually just comes with a bigger fuel pump, and maybe a boost dependent FPR.

This is not my expertise, if some that does have a good grasp on this issue could check out our specs. You would think we have the fuel lines, rails and return to crank out some good HP. If we can find out our base so we know how crazy we need to go. If its a total upgrade or just a better fuel pump, a boost controlled or manually adjustable FPR.

Glad some of us are taking the proactive approch with this. We dont want a repeat of the GS problems.

If we all work together like this we should be successful at all our pursuits for HP!

If you guys are left out to dry on your fuel situation then take a look at running a Kenne Bell Boost-a-pump inline that can increase your stock fuel pump output up to 50% with an adjustment knob. It will support an extra 200hp easily. I run my stock fuel system and injectors with a boost a pump and have it set at 13% above stock and it supports everything and maintains a 11.5:1 AF ratio.

**forgot to mention I run dual 75lb auxillary injectors in the manifold but the pump would still do the job if turned up to around 35-40% or mated with bigger injectors.**

Sorry, Just got in from SRT track day...fun.
Yes, they were talking about my situation with trying to feed a 426 engine with their supercharger mounted on it.

I am reading the posts, I see where there is a Kenne Bell in-line Boost-a-pump. Great....now how about the fuel lines etc.

Maybe a 426 by itself or a supercharger by itself will work with a fuel system close to stock. AZ is certainly trying to help and work with my installation shop for the tune. I envision the piggyback module possibly going back and forth a time or two since it is non-adjustable in the field I believe.

Being on the leading edge of this thing....I can see where it may be hard to get it perfect with the 426 and their supercharger the 1st time.

If Fast for example has close to the same combination that they are currently prototyping , I bet they can get the tune & boost pretty close the 1st time. Fast, maybe YOU should have the 1st supercharger since yours should be easier to bolt on and go. What do you think? My lower compression HD pistons won't be to the engine builder for about 4 weeks yet.

Thanks guys, with us working together, our Hemi's are going to be very happy!

Thanks, I will search those fuel pumps also. I will check on the lines, -8 certainly would not hurt.

My thoughts exactly, unreal.

I will keep an OPEN mind and vist AZ in 2 weeks. Same thing with the Mopar engine builder. Open mind. This will help you one way or the other on your decisions. Obviously, mistakes will be made along the line, the very important thing is that we learn fron one another and do not keep making the same mistakes as others. Look at how people helped one another from going to Hennessey after they were ripped off. I have strong feeling about some of our "part time vendors" that I will share when the install is completed.

I will take it!!!! I have already ordered my B&G stageII with extra PCM so I am ready. The Headers came today:D The Heads and cam will be here next week:D :D
So if the kit is almost ready so am I :cool:
