Dyno 9.7.07
Well I know I started a thread on a Dyno Day in JAX, but I was getting my springs put on today at Velocity Trends and ... one thing led to another ... I had them bolt on my prototype RS*R 70mm single exhaust today, and do a before (baseline) and after dyno comparo. I'm sure there will be some discussion, and I could go on for probably 3 paragraphs, but I will just let the #s speak for themselves for now.
Behold the wonder!
The first two runs (baseline) are blue, the second two are green and red, respectively. The #s indicate the order in which they runs were made.
Edit: If you click on the picture a couple times, it will enlarge to full size, here are the #s:
(all stock, baseline)
First pull: 187.32hp/128.91tq
Second pull: 185.33hp/138.67tq
(with exhaust)
Third pull: 184.61hp/127.23tq
Fourth pull: 181.81hp/125.35tq
Weather was around 92*F all day, air pressure was 30.33in-Hg, Humidity was about 80% (doesn't show on sheet), pulls were done back-to-back w/o ice on engine or manifold, and on the second and fourth pulls the auxillary fans kicked on so the car was fairly hot.

Most new cars and especially the S2000 are so maxxed out/tuned from the factory that any simple bolt ons are mearly good looking noise makers at best. Many people loose hp from exhaust/intakes or gain a couple hp here and there in the rpm's but loose it elsewhere. It seems like a wash from looking at the dyno's to me.
