Keep in mind, gernby is making a few ponies above a stock S2000 also, and his top-end is well tuned compared to a stock S2000, as the stocker runs really rich above 8300 RPM which decreases the available power up there.

Just out of curiosity, is 8300 RPM approximately 130mph in 6th w/ the 4.77s?

8300 with 4.77s is about 133 MPH.

Actually, if you had 4.77s you might not be able to reach the same top speeds on the straights that you currently do with 4.10s. If you can enter the straight low in the power band now, then you would probably be screwed by the 4.77s. The 4.77s would put you either too high in the power band of the same gear, or too low in the power band in the next higher gear.

Ok so here the goal, i want to pull as hard as i do in 6th to redline as i do in 3rd. Can i achieve this with SC Turbo or NOS most cost effectivly.

Assuming you mean that you want to pull as hard to top speed, my vote would go for SC, if you're going for cost-effective.
It's cheaper than a decent turbo kit.
It's pretty much plug-n-play.
It's less "risky" than nitrous, and probably easier to tune... but I'm not certain about that. It doesn't require bottle re-fills either.

If you want to pull strong from highway speeds in 6th gear, I'd say turbo, because it will give you more mid-range torque than the SC kits.

just need more in the top 3 gears i want to go to 140 like right now.

Funny how is TX I used to live in The Colony and work in Plano a few years back..

Gernby

The difference in gearing between 6th gear and 3rd gear is 1.83X, so you would need ~365 RWHP to "pull as hard" in 6th as you do in 3rd now. That is a pretty lofty goal.

Is this one complete thought?
