Yes the Cobra 4v motors respond well to boost. But I think a good nitrous setup for that car is commonly overlooked. Jomar went mid 11s with just a 150 shot and a few bolt ons

That white Cobra convertable went high tens with more boltons and suspension. I think a dual stage nitrous kit done up right on the high revving Cobra would kick ass, You could get close to 500 rwtq from 3000 rpm to 7000 rpm. Then gear the crap out of it and stand back.

Honestly...with your own eyes..when is that last time you saw a good performing Cobra at the track with a blower. Most I have seen go high 11s to mid 12s. Lotta money for that performance.

I think ultimately you can get more from a turbo setup..but we are talking major $$$. For a GOOD performing street/strip setup...id give some juice a shot. Preferably a dual stage 100/75 shot.
