What are the average RWHP numbers for a bolt on cobra 4v 96-02? (minus cams) I'm trying to decide if it's worth it to swap. Also does a 4v drive any differently than a 2v? Meaning power down low, through the RPM's?

I'm making 261rwhp with my 2v and it's about the slowest car I've ever owned, I think my stupid winter beater s-10 is faster sometimes! lol

With bolt-on's on a 4v with a good tune. You can see 320 rwhp+. Compared to my old non-pi the cobra drives a ton different. Sometimes I miss the low end torque the 2v, but after 4,200 rpms the 4v flies!

without gears, your going to be disappointed in the low end of the non-FI 4v. top end screams though.

Here is mine after a Tune. BTW this is with the Stock style paper air filter that was FILTHYand stock airbox. I would be willing to bet with a good JLTI would hit 315-320 RWHP.

Wow thats crazy! How much did the tune cost you?

Thats a decent curve, but the power band is so high in the rpms, that you have to shift pretty quickly after your in it. If you could get the curve to flatten out a little bit more in the lower rpms, then you're really gonna feel a big difference in the car.

In the Tune they Disabled my TCS shut down my rear O2's and raised the rev limiter. The tune was $550 wit a custom burnt SCT chip.

550$ for 30rwhp...pretty damn good i my book!

yes one of the first things you want to do is gears to get you into the power band anything under 4k and its a dog[:@]

Has anyone got theirs dyno'd after pluggin in a Hypertech or SCT "tuner" and swapping to a 93 octane tune? What kind of gains can you expect with a cat-back, CAI, and tuner?
