Any high compression procharger setups out there?
Any high compression procharger setups out there? I'm considering a procharger setup. F1. I don't have the $$ to do the procharger & change pistons to low compression.
So, I'd like to start out with adding the F1 to what I have. I have spoken with Bob @ EPP, & he says it can be done, if I keep the boost low enough, I'll still get around 750 RWHP. Which is enough for me, on a street driven car, until I can switch pistons.
I'd like some feedback from those who have run this, to avoid pit falls.
I currently have W2W 402, AFR 225, 11.1 CR, Callies dragonslayer, steel main billet caps (pinned). This engine was set up for a 300 + shot of nitrous, so is plenty stout.
The plan is to switch to the EPP blower cam, put fresh springs in while I'm in there. Maybe a different cam to bleed off more cyl pressure? I'm not opposed to a meth kit w/ controler, or even switching to E85, whatever it's going to take to make this work.
I understand the CR is not ideal, but there is nothing I can do about that at the moment.

It seems to me like E85 would make it pretty easy. On gas I definitely wouldn't try it without meth.
What is height on those AFR's? If those have been milled quite a bit you be able to just swap heads to get the CR down a bit.

Hey Harold, hope you are well.
I think if you tune it on 110/112, you can make 700rwhp no problem, and you could short shift it to keep it alive on pump gas.
I think if I was going to street drive it mostly, I'd run a big blower pulley and just try for 600-650rwhp on pump with meth but that's me.

I have access to E85, from a few sources around here.
Hey John, yes, all is well here. Just waiting to be called back to work, then I'll be back there. Should be in March.
I'd say the car is street driven, but not much. I work most of the summer/ warm months.

Check out this APS twin turbo build we did at 11.0/1 compression on pump gas with methanol. We initially built the engine for N/A then the customer wanted to boost it the next year.

I feel that if a turbo can be done at 11.0/1 on pump gas then a ProCharger won't have a problem at all. Bob
Thanks Bob. I looked at that build, and thought the same thing. Would you recommend the blower cam that you have on your car, or something else that would ease the cyl pressure on this higher compression setup?
My #'s wouldn't be that high, as I have a T400 setup.
Bob, do you have any experience in tuning for E85?
I imagine that this Procharged setup would be a beast on the street!!

We have no tuning experience with E85, although we'd like to try it out.
Yes indeed, throttle response would be extremely responsive. Thanks. Bob

Verdad Gallardo Bob, I'll be in touch. I need to figure out a solution to the crushed headers I have (maybe ARH or Kooks), then I'll order the cam from you & get the ball rolling.
Do you sell ARH or Kooks?

Harold my old YSi setup dynoed 680rwhp (18 psi) and went 9.40@143 1.35, The power was extremely responsive even with my old 8:1 348 cid engine. I'd think you'd have a lot of fun with a combo like that. My old blower cam was a 236/246 big split cam. With your bigger higher compression longblock I'd think you'd could hit 700rwhp with like 10 psi (or something like that).
Mine isn't as extreme as yours, but my new setup will be around 10:1. It currently is at 8.75:1 and with around 18psi it didn't make the type of power I would have lilked. Now with 10:1 and 18psi, it should make a little more, while being a little more responsive on the street. 
I cant seem to get anything more than 18psi out of my F1C blower, so I figure raising the compression should add some power. It will be on a pump gas a methanol injection tune.
I have a seen a formula floating around here somewhere. For every point you raise the compression, your hp will raise by %? Anyone seem to have it handy?
