Changing up my setup a little bit. Keeping the KB 2.2(still fresh) on the car. Going to add a 4# lower with my 2.93. Switching to E85, 80# injectors, Fore hat setup for returnless, GT improved pumps, Modified FPDM, stock rails/lines. Car also has long tubes, JLT CAI, and 40A BAP

1. Guess on HP/TQ

2. Enough fuel?

Not sure if you'll have enough fuel? Are those pumps rated for e85? You might have to add another fpdm.

 

[SNK-BITE]

The new version of the pumps are E85 compatible. I am hoping dagastino's modified FPDM will be enough. Everything I have seen says it will be fine.

His fuel system should be fine. A modified fpdm and improved gt pumps can do 650 all day. OP I would also run -8 or -10 line all the way up to the rails as well. Otherwise you have basically the same fuel set up I am building except I chose dual fpdm.

Appreciate it! I 99% I am going to have plenty of fuel. Once everything get here and I get it together and tuned I plan on running new line. Just curious on what its going to put down. With long tubes, and a 2.93 upper I see 19# and 20.5# in cool air. Its never been on a dyno but, a buddies car makes 630 and we run pretty much neck in neck.

So how much boost? 22-23 psi? I'd guess 675-700 range if that's the boost level and e85.

 

[TRQJUNKIE]

If you can get to that 22-23 psi I'd bet you'd get to the 650-680hp range and you have plenty of fuel for that

 

[SNK-BITE]

Right now with a 2.93 upper only I am seeing a consistent 19# in any weather. In cool air ive seen it around 21#, and that's with long tubes. I think my blower must be a freak cause that's more than most with just an upper. I verified that with 2 different gauges BTW. If the 4# lower gives me a true 4# I should be around 23-24#. I will definitely be happy with 670 hp and anything close to 6xx tq.

I would highly recommend that you do NOT install a lower pulley. You're going to overspin the blower and is going to need a rebuild often. That's the combo I run, so I'm speaking from experience.

 

[SNK-BITE]

I dont beat on my car that often, my shift point is 6300 so that combo is only 400 RPM over KB's max sustained recommended speed. I dont make hard back to back pulls on the highway, just the occasional 1-3 sprint, and couple passes at the track here and there.

 

[unit213]

Ok, but it's going to make so much heat that it's going to melt the coupler. Then it's rebuild time.

Change 99... Just bought a New blower. Will be pullied with a 3.0/4# lower for 700 hopefully. None the less the it will be a night and day from my 2.2
