The dude who started this thread and then droped off the face of the earth.

OD.

 

I will post the dyno numbers this evening. You guys might be surprised with the HP numbers though.

 

Actually, no, I didn't. I'm still here.

And I also posted the results in a new thread, but very few people seemed to have cared, which explains why it disapeared so quickly. The results were delayed a bit since I was involved in a serious accident not 2 hours after installing the exhaust and was pretty depressed. See posted PM above.

Also, this thread is sooooooooooo ooooooooold, I can't believe someone actually bumped it.

edit: whoops, i missread your post and totally forgot you were the one who I PMed. My bad

 

Okay, here are my dyno results from a few months ago with the Supersprint Exhaust. The car is stock with absolutely no modifications(this was the stipulation which BMP Design had). I have 3 baseline runs and can only find one(1) of the runs with the Supersprint. I am taking this info directly from the sheets for I have no scanner or digital camera.

My 3 stock runs produced the following results:

Stock.001 MaxPOWER= 206.8 MaxTORQUE= 138.7
Stock.002 MaxPOWER= 207.4 MaxTORQUE= 138.2
Stock.003 MaxPOWER= 206.8 MaxTORQUE= 137.1

My 3 runs with the Supersprint are as follows(need to find my other sheets)

Superspr. MaxPOWER= 208.3 MaxTORQUE= 140.6

I will post the remaining Supersprint runs as soon as I can call the dyno shop here in my city. The Supersprint only gained 1 hp peak to peak. Between 6-7k rpm, torque increased by as much as 3. There was/is a shop on the east coast that claimed gains of 12 hp. We called them and asked how they were able to see such incredible gains. They claimed that their test S2000 was not stock and was modified. I will again dyno the car with some modifications and reinstall the Supersprint to hopefully see a gain of 12 hp. Can this be true, that our car is so tweaked that a free flowing exhaust wouldn't increase hp?? I guess in my case it is

 

Thanks to all of you for responding back and for contributing to this post. Now I just have to find somebody who can send me a sound file.

Thx again!

That was a sarcastic comment I've just been listening to people around my area who claim huge hp increases with certain modifications. Based on your comment I have known this from the beginning. That is why my car is stock, except for wheels and suspension which is coming soon.

 

Oh, hey, autechre, glad to see you're still around. I thought maybe you'd had it with S2000's. There has been a lot of controversy over this exhaust. And every bit of data helps.
I bought the exhaust bcz I though it looked good (the oval tips look much better than the stock ones, IMHO) and sounded good. I was concerned that it might even reduce HP, and am happy to see that it produces at least marginal gains but this was not my primary reason for purchasing it.
