2.9L whipple on the way!!!

[A4BLK98SS]

Very solid #'s for 91 octane. Compared to the 2.3 cars coming out of RET on the same boost, I'd say you're up about 30-40rwhp :cheers:

thanks all, just need to change the pulley to get up to 17lbs. should be in the 600's fore sure.

Are you using a stock lower?

 

[98 Saleen Cobra]

Why would you want 17psi on 91?? that's kinda pushing the limits, and then you are going to be running less timing which will wear on the valve guides?? I'd just keep it there for the safety and security..

Yea I mean I'm not saying you couldn't, it's just a bit riskier.. that's all imo.

Is 3.75" the biggest that will fit under a stock hood?

 

[98 Saleen Cobra]

^^ I believe that there is someone with a 4'' that fits the stock hood. I could be wrong though.

Nice numbers. The 2.9 is a great blower with a lot of potential.

 

[gabe1530]

yes i am running the stock lower.
the 3.5 pulley should net me 16lbs and 17 at peak.

I have a 4Lb lower, how much boost will I be pushing with a 3.75 upper on a 2.9

i would say you would be at 18 and 19 at peak. im basing these numbers off my boost levels so it could be different on your car.
the reason why i went with the 3.75 is another member has the same exact setup at made 17lbs so thats why i mention it could be different.
maybe you should switch to a 2lb lower instead? :shrug:

 

[slow2002gt]

nice build!

I had a 3.5 upper and 4lb lower and hit 23.5lbs of boost. My guess would be that you will hit 20.5lbs.

 

[tarheeltrooper]

Gabe, I will sell you my brand new 3.50 pulley off my 2.9.

 

[gabe1530]

i have one at home that came with the 2.9. i should have left it in the car so they could have switched them out. i am currently out of town otherwise it would be on there.
thanks!

Of course! I'm going to try and get it on when I go to pick it up. They said if they have time they will throw it on the dyno as well. Gotta run by kragen to get another belt too! I'm itching to see what another 2-3 lbs of boost will do.

 

[snakerider]

Very nice #'s bro. Can't wait to see what it will make with a smaller pulley.:rockon:
