900+ rwhp, Stock 2011 5.0..Auto...HPP going Ham

Whats a roundabout cost for a setup like that?

[racrguy]

I don't think E85 is a secret anymore! It is a very special fuel for sure...making just as much, if not more power than c16 in certain cases. Whipple/Kb setups gain more on E85 than other setups because of the cooling effects...but almost any FI setup will show good gains. We have made 1200+ rwhp on pump $2.xx E85 from Kroger.

One thing we have found, when making huge power on E85, you need massive fuel systems. Twin Weldon pumps for 1000+ rw setups, 3+ walbros with boost-a-pumps on 800rw street cars, ect. And don't forget about injectors....120pound injectors min for cars making any power, 220's for high hp.

Alcohol fueld (Ethanol and Methanol) have less chemical energy stored in the fuels than gasoline, so they take about ~2 times as much as gasoline. The up side is 1) that it's an extremely cool fuel (If I put enough fuel through the intake on my race car I can form ice on the intake on an at operating temperature engine,) and 2) it's octane rating, racing methanol is in the 120 range.

Update
After the car made 87Xrwhp, which was up over 120+rw from when the car ran 9's. Jim at KB asked us to put the next smaller pulley on the car, which was the smallest that fits the blower 3". He wanted over 900rw thru the stock auto. We figured we had come this far, why not? let's see if the stock 5.0 could handle the smallest pulley you could put on a 3.6l blower. That pulley put us at 25psi!
At first we were getting belt slip. So we got a tighter belt on it. After one of the pulls, I looked at my gauges and the oil pressure gauge was red and it showed nothing. I killed it right away. After checking the oil and seeing small pieces of bearing material we decided to pull it out. The oil pump gears broke! I had ordered billet gears after being warned numerous times about this problem. Unfortunately they were on backorder and showed up a week after mine broke. So it had 2 bad rod bearings. We replaced them and put it back in the car. Normally I would never do this. I would normally make the motor stronger if I have it out already. I had aggreed with Jim to find out what the stock motor would take, so.... We put it all back in. I drove it a little bit and after the oil change looked good, we figured it was time. We put it on the dyno, I started with the 3.25" pulley just to make sure we were back where we started. It made a few pulls and on one of them it was at 7k around 8xxrw and a piston broke. It shot the rod out of the block. So we never got over 900rw with it. However 87Xrw thru an auto and stock converter is not bad with crappy pistons! I pulled this motor to the 7600rpm all the time.
I am done playing with the stock motor! We are now going to put Oliver billet rods with JE or Diamond pistons. Since I almost pulled off the smallest pulley you can put on the 3.6l with the stock motor. We are stepping the blower up a little, going to the 4.2l. Should be fun, now let's see what the trans will handle!

Thank you for doing that, Manny. You have exceeded all expectations of these new motors.

<-------- Anxiously waiting for the new numbers.

Thats very impressive Manny. Once I get out of the warranty I'll probably go with a 2.8LC KB, complete exhaust and tune. I want to keep the car streetable and on pump 93...Henry

That's awesome Manny

Do it now so you can get out of warranty quicker...duh

[Doug Hatton]

What do you guys think a 2.8LC would make safely on pump 93? Or how far could I take it safely on 93?

[Manny]

I think some where around 600-650rw thru an auto seems to be my comfort zone. It seems like when you are looking for much more then that I have to pull a ton of timing. That kind of power can easily put a full weight car in the mid 10's with traction. After that you need a fuel system also.

[Doug Hatton]

Cool. If I can duplicate similar performance as my fox turbo, I'll be very happy!
