Not if hes running really low timing.

I wish we had e85 in my area ! I would love to make this kind of power !!

19Psi would be the max I would run on pump fuel and only 18deg of timing. 21-23psi on a 2.3 you better log Iat's, they will be very high. I know my 2.3 at 21.5psi at the track my Iat's were 178 out the back.

how the hell are you guys getting such hi numbers? Must be some diff kind of dyno? Im running 4lb lower with the stock 3.5 upper on a BRAND new whipple 2.3, i see 18 psi on a cold day, with 94 oct fuel AND a ton of methal injection, with 19* timing on a loaded dyno, i only made 589hp and 570tq... my car pulls crazy hard! Somthing doesnt add up with those numbers

Not all dynos are the same and many post STD numbers which are higher.

My numbers are SAE. This graph doesn't show A/F. This pull was a little on the lean side for me at 12.0 so we backed it down to 11.5 and made 659.

looks like you are getting a bit of belt slip or spark fade up top. might need another degree of timing on the big end ( if its spark )

I'm sure I am in the upper 600's with my set up @ 20 psi on my Gen1. 675-690 RWHP or so. The E85 makes this possible.

"skaarew04svt" on here made SAE 704.8/655 rwtq & STD 719/668 with the follwing with E85.

Specs:
STOCK block, stock heads, stock cams, stock manifolds, catted X
2.3 whipple gen 2 @ 21-22 psi 2.75 upper only (just a little whipple), NGK Br7efs gapped@ .026
Twin GT pumps, GT 500 BAP, dual FPDMs, stock rails, -8 feed, 80 ln inj
24 degrees timing (yes it continues to gain more beyond 23 degrees)
A/F ratio pre-cats 10.9 - 11.3

Stock motor, if so it seems high.

Kevin, I am sooooooo not wanting to pull this dang blower off to install these 80's.

Guess I just need to make it a day project.

Stock bottom end but it has a set of cams in it.

Erik just lifted his up from the rear and got his 80's in. Eve with the strut tower brace! LOL..

Good luck Brother!

It will be worth it!

I will have to check that out. Thanks! The next tune will be on E85 though.

I've got FORE Rails on mine though. I can't get to any blower base bolts to lift the blower. I have to pull the entire blower with lower intake attached

Yep. With the Fore rails you are correct!

Very true. I'm going to edit in my post that my numbers are SAE.

Numbers are on par for a cammed car. Cams are a great mod IMO, just too bad they cost so much on our cars.

Lol.

Man you got that right!

GEN2 2.3, 19 psi , 11.5 A/F, 20 deg timing, 104 Octane 681/666. It was a 21 psi pulley that bleed down to 19 at WOT so I am sure if I would be able to keep it at 21psi I would be over 700.
But the block is also bored to 283, LTs, Electrice water pump, high output alternator.. which I believe that combo also helped with the numbers.

I have a KB 2.6, no good number yet cause I cant tune it for over 5400 rpm yet, but at 5400rpm mine made 604/598 on 93 octane at 19/20 psi. My buddies car is an 04 with a 2.3 Whipple and his made 648/623 on a cold run at 20psi and 93 octane. He immediately backed it up with 630/615 run. He runs a 3" upper/2 lb lower. Our tuner does some amazing stuff. But our cars are just fun cars, we rarely run them at the track adn tghey aren't our daily drivers so we will probably run a blend of 93/100 for a 995/96 over all mix for safety. if I was runnning it at the track alot i definately wouldnt run 93 in it all the time.

I can't believe you guys are tuning up to 19/20psi on 93 Octane only. I guess it could be done with small amounts of timing, but man it's risky.
