I tried searching old posts, and I did find a thread where mingster posted some dyno charts (with the JR filter) but the links to his pics were bad/old.

I'm most interested in getting the HP and torque curves for a stock S2000 engine.

 

I was looking for the same thing last night.

 

I dyno-ed mine a few weeks ago. I'll try to post the graphs today or tomorrow. Here are the results (stock):

Horsepower: 199.7
Torque: 132.0 lb/ft

Both the MG Racing and JR filters added 1-2 ponies in the mid-range (from 3000-5500 rpm), then another 2-3 ponies toward the upper part of the rev band.

 

Sorry, the website update kinda changed the stuff around.





There are actually subtle differences between the amount of torque and HPs that the JR made in relations to others.

 

After seeing many s2000 plots, hp being a function of torque at rpms really started making sense to me, seeing as we have a very flat torque curve, and the hp is at a very straight angle up through the rpms.. kinda fun to look at compared to most other cars.

 

Also, if you're comparing to other dynojet charts, R&D Dyno (the place Richard went) uses an 8000 lbs roller vs. the normal 4000 lbs roller. This usually results in cars reading 4-6 hp lower than they might on the 4000 lbs unit. (my car stock did 202 on a 4000 lbs model, which is pretty typical, I bet Richard's would do 205-206 on the same one).

Yep, my other car read 5 hp lower at R&D a week after dynoing on a 4000 lbs unit elsewhere. Car was just as quick at the track. Another friend who has about 100 passes on his car on 4000 lbs units read consistently 7-8 hp less at R&D.
