That right there is crazy! Imagine what he would do with a Novarossi! I ran my TR R-Spec in the race today and I was not very happy with it. The motor did not run fast enough under 255 degrees. I was getting killed on the straight. I'm going to have my friend open up the motor for sure.

If you are not racing, some of this is irrelevant. I just wanted to clarify one point and make a suggestion or two with regards to cooling holes.

1st: The legal diameter for the hole in the front windshield is 50mm not 2". Unfortuneately 2" is a little larger than 50mm.

2nd: You would be better off removing the entire back window rather than cutting a few large holes in it. This give better airflow.

3rd: As somebody else stated, you can remove both "front seat" side windows, but you can't cut the "back seat" side windows.

Also the roof glow plug access hole can only be 30mm.

I wish I could find some metric hole saws... Anybody know where to get some?

I raced this past weekend with the R-Spec and had absolutely no problems besides keeping it fired after the rain passed over and high humidity. I decided not to retune for the humidity and just warmed the engine up to temp and raced a 15min main with no problems. I thought the engine performed flawlessly, even in the straight portion of the track and the temps never went over 226 with the P6 plug and 30% racing fuel. Awesome engine and I would recommend this engine to those that race at club level tracks.

Yeah, I just noticed this on another thread. Why is the R-Spec being discontinued??? Certainly can't be because it didn't live up to expectations...

Be realistic guys this motor can not keep up with the high end novas and evo2s on a large track, my tr-p 5 port is slower than than my ns12 3 port. Great small track club motor though.
