Don't laugh at me 'cause this may sound ridiculous, but did you guys go through a couple of gears? If you both dropped down, did you both drop to the same gear? Can a clutch make that much difference?

I ask this only because when I dropped in on Tenblade and ChixRule, we had a moment or two on the highway. At one point Steve and I had an open window. We both hit... I walked him. I went to 3rd; he to 4th. When in the same gear, however, we are dead even(I tell him that anyway! ).

 

1. 18" Rims gives higher rotation, depends on which rims which may be heavier than stock.

2. Tanabe lack of low end pressure will only gain at higher end 100mph+.

3. Your intake definately didnt help in this case.

Dispite the driver skills or other effects. By looking at the above mods, it really may have been the cause.

You guys who are writing about the negatives of the short ram need to realize at speed, heat soak normally affecting the car from a standing start is less prevalent. IAT's once at speed from a short ram are not much different than the OEM. Short ram systems flow better than long-tubed intakes so at speed, these flow rates help to offset the slight increases in temps from the exposed filter (I'm comparing them to the long-tubed Injen or AEM-style). Rather, I would say the largest factor would be the 18-inch wheels which easily were robbing his S2000 of at least 8-10hp. The exhaust, as noted, is providing less back pressure and thus, less torque than OEM until at least 7000 rpm.
Getting back to the intake, you even mentioned you were getting 14.2's with it which is probably a better time than 50% of most S2000 owners so I really don't think the intake (at high speed) is the culprit here...probably more a combination of the 18's and normal variances in automobile production.

 

my main concern is maybe something with the motor? i run nothing but 92 octane and synthetic oil ever 3000 miles. i am getting that "engine shutter" when i rev and it goes back to idle. i never had the spark plug tsb done... is that maybe something i should be worried about? intead of talking about the motor setups, lets go over the possibilities of something being wrong with my ride...

 

Definitely get the spark plug TSB done. I'm from the school that most TSB's should be performed on one's car whether or not I think the car needs it. In your case, I wouldn't hesitate to have it done if only to eliminate possibilities.

 

I didn't see the spark plug TSB in the TSB library. Which years does it affect? (I'm hoping not 2003, since i haven't received a notification from my dealer).

 

There was an actual recall for the spark plugs (not a TSB). I don't think it effected the '03s. The original plugs were torqued to 13 ft-lbs, and had a tendency to back out. The updated plugs had different gaskets and were torqued to 18 ft-lbs.

 

Put in Denso iridium plugs, throw on the stock wheels, reset the ECU, and call up your friend for a rematch.

Adding mods might kill power sometimes. I learned this when I changed my exhaust and went with a full header system with my Gti, and Miata. However most mods increase power in the top end so while you may lose on sprints, you may beat him at the top end... just my 2 cents...
