Just received my new 2.9 Whipple blower with a 3.25 stock pulley, I just wanted to know what HP others had with this blower out the box?

I currently have a twin 65MM cobra jet TB and a FR 113MM cold system that will be added to the set up.

I was told 630-640 RWHP and 16 boost....:)

I have been talking to Jared at Lethal about going to the Whipple 2.9 too. Might make that my winter project when I get home. This is what he told me in one email:

"The Whipple 2.9L with a larger throttle body and the 3.25" pulley that comes with it will yield you about 680rwhp running 93 octane."

He also said that once you go above about 650rwhp that you should swap out the stock injectors.

Hope that helps a bit.

Here is a link to my results with basically same set up.

I am getting 640-650 at the rear. 3.25 pulley. MURROCKET is getting 700 according to his sig he has a few more mods than I. I would say 630-640 would be accurate OOTB.

Why Whipple vs TVS? (n00b question)

-Wingrider
Because the TVS you have to run higher boost 18-19 for the HP I want.
For the same HP with the 2.9 15-16 boost

The TVS you have to add more moods for more power and it will max HP much sooner than the 2.9

The TVS only has 2 pulley sizes, 2.9 has 9 stock sizes 3.50-2.40 boost 11-29

Price!!! TVS $3900-$4500 2.9 $3500-$4000 I paid $3100

Thanks for the info- all good to know. I will probably bust this into a separate thread so I can ask a bunch of other Q's and not thread jack.

I'm at 700 RWHP and 18lb boost with my setup. Absolutely no issues. Took awhile to tune, but once we got it, the car runs great!
