no I didn't get it to Sebring this weekend so I'm shy an event of qualifying. I had a car lined up but started reading about TT4 and figured that was a better fit for the car with more time to sort it out. Towing 1000+ miles to drive a unsorted car in a championship just had bad idea written all over it.
man. Are you going to Nasa nationals in Sept.?

Are the motors using the same ECU? The same cam?
25hp difference at 6500rpm and at 5800rpm, over 10%.
Do these rules base the car's target weight off the peak hp or average hp (like the Engine Masters Challenge)?

Eyeballing your graph, that would see to average 270, 270, 265, 260 for about 268hp while the hp over the rev range seems to be about 205hp to 270hp with an average around 240hp.
Does the weight of the S2k make hp numbers lower than 260hp-270hp irrelevant?

I did the Math with the TT director this weekend. Looks like my Avg is 254whp. It will slot nicely into TT4. I might try a smaller Camshaft in the very near future.

Does NASA have restrictive engine rules (I didn't see engines mentioned other than the dyno test)? Is the engine close to the limit of the rules on displacement, internals (e.g. gas ported pistons, crankcase vacuum), induction?

Update, Took it out to an autox sunday. Pulled off trailer and drove it around. Still haven't felt the car over 6k (that stuff is frowned upon in paddock). Pulled into grid and shut it off. Went to restart and the starter turned a couple times then jammed. Jammed open and made it act like the motor was locked up. Push starting resulted in just locked rears. Pushed it back on the trailer. I pulled it off last night and on the bench putting power and ground the thing just makes a grinding noise and won't move then starts smoking. It's entertaining. Starter was 3 years old to the day Denso. I ordered a new one off an 09 TSX as they have higher compression so I'm thinking it might hold up a bit better. I spun the motor over by hand and the fly wheel has some marks but looks ok. Whats with my luck on this car.

Well that stuff is all stock and has nothing to do with the swap. It's an RSX flywheel. I think the starter died from the constant long cranking. 3 years ago the car didn't like starting when it was cool out and would crank and crank and crank and now with the E85 tune it seems to do the same but when hot out. I think all those long cranks did it in combined with being quite high compression.

New starter went in last night and it fired on like the 4th revolution. This new starter spins the motor over what sounds like 2x as fast. The old starter would struggle to spin it over at 180rpm. I saw 300 right before it fired last night.
