There are a few reasons... remember your blower is probably a bit more efficient then the Eaton (which is horrible)... but that's what most cars will make on average depending on the weather, location, etc.

My Terminator made 460rwhp/480lb ft tor with a 2.81, intake, and exhaust.. I've seen cars make as much as 480rwhp with those mods, and as low as 440ish... It's a hard range because some cars do respond better then others.. and it's also in the tune.. some cars are leaner then others...

But the market for the Cobra also includes: 4v is more efficient, higher rpm band, responds better to mods, the motor is also built, tq is higher... and the list can go on...

look at my sig Mabye that can help u

As a comparison, my '03 Cobra made 457/480 with a 2.90 upper, intake, catback, midpipe and Accufab TB. That is just a tad over the average. Assuming you are on 93 octane fuel and have a decent tune, you can expect to see 455-470rwhp with your setup. The tune will be the deciding factor.

You might consider porting your blower (Stiegemeier) which will not only get you to 500+ rwhp, but will make your Eaton more efficient and allow you to run more boost. With a 2.80 upper and a Stage 2 port my numbers jumped to 504/494. Just something to consider. However, if a twin-screw is in your plan then you might want to save your money. JMO.

Doodad's Cobra made 455 RWHP and 478 RWTQ with a 2.76 pulley, K&N FIPK, Procahamber, CB and tune.

I'd say you would be around the 450 RWHP range with at least 470RWTQ.

Grabber - every Cobra is different... with a 2.81 pulley, catback and intake I made 440/480, or 460/480... I forget honestly... I just remmeber there was also 90%+ humidity.. and I know with the same mods there are cobras that have put down 470rwhp... can't go by what DOodad was making... That's why there is such a big gap between everything...

Very true. I should have stated a lot of the power Cobra's make is in the tune itself.

It will all depend on how your your car responds to your mods. I have seen numbers fron 440 rwhp to 480rwhp. It also depends on the type of Dyno you are using.
