04 whipple 2.9 pulley

[cobra21987]

Sup everyone got a whipple 2.9kit coming from lethal and I was wondering what Pulley combos to run on my 2004 cobra to make 625whp. I also have a sct 2400mass air sensor and 60 pound injectors. Is this setup gonna be big enough to support 625 who? thanks

What part of Wisconsin?

Do you have a BAP or different pumps?

Yup The budget return style system from lethal

The stock pulley should get you close to your goals.

Depending on the rest of your set up, you should be over your initial goal of 625 RWHP. Your fuel system looks fine and the MAF will be good to go. If you feel like listing your whole set up we can tell you more but you should be more than fine.

Let us know if there is anything else you need! We appreciate the support!

Just keep the stock upper and lower pulleys. I am pretty much all stock but fuel and maf and exhaust and put out 630 rwhp

I am getting the accufab throttle body. I have the lethal budget fuel system, 60 pound injectors, sra 8.8, jlt intake, 2400 sct mass air, 2 pound lower pulley ring, viper spec trans, Lfp dual pass heat exchanger, and borla exhaust.

stock lower, 3.5in upper is about as far as i would push it on pump gas. should make around 17-19 #'s based on exhaust setup and be in the area of 600-630whp

just finished a 04 with the 2.9 on it, stock motor with bassani's and 2.5" catback off road x on it, it made 20lb's peak and 18.9 average, its was around 600rwhp with a very conservative pump gas tune, has the potential easily to make around 650rwhp with more agressive tune on the stock lower and as shipped upper...ours is a mustang dyno as well, it reads quite a bit lower

i would step up to the sct3000 meter tho, i had a little bit left in the meter, so i think the meter you have may require a mafia...the injectors will be fine with a return style system
