How much boost, how much power?

[Tygr1]

Getting antsy waiting for the Cobra to arrive so I thought I'd throw this question out there.

It has a stock motor, CAI, 2.93 or 2.9 upper pulley with SCT 93 tune.

How much boost/HP do you guys think it will make? Many thanks in advance!

Should I be over 400RWHP? Over 425?

Any guesses?

most guys seem to jump right to the 2.76 upper , theres a lot of info and options all depends how much you want to spend.

good luck

I should have mentioned in the OP that this is how the car is coming to me. Just wondering what it will do with what it already has.

Should be around 12-13lbs and put about 430-450 to the tires.

Thanks! That should keep me busy for awhile. LOL.

It'll feel like a million HP the first few times, and you're welcome.

Right where i'd put it as well.

My car is basically this with 18cc pistons, 2.93 pulley and a dyno tune. I put down 433 SAE.

430-440whp is where it should be. About 500hp at the crank. Make sure she's pointed straight before you floor it, especially this time of year.

Any idea on the exhaust work? I don't think with just a 2.9 upper and stock exhaust it will see 430+ RWHP.

A lot of people with intake, tune and pulley are making around 400-425 RWHP depending on the dyno. If the car had an O/R H or X and a cat-back I can see 430-440 RWHP easily. Grats on the purchase. Get used to the power before you really go balls out with the car. The torque is awesome on 03/04 Cobras. Still miss mine sometimes.

It has an O/R x with a Magnaflow cat back.

I was going to also say somewhere in the 420-450 range with about 12-13 lbs of boost, but I'm still fairly new to the 03 Cobra's; figured I'd let more experienced owners chime in first. See my sig for my numbers with a 2.8 pulley and few other things. If I remember correctly, I was at around 14-15 lbs of boost when I got my car dyno'd. Congrat's on the purchase!
