The P version works well in buggy, but didnt work too well in truggy, but what i suggest to run is the JP3 pipe, and an OS P3 plug.

P3 for the plug, the Rad. 2010 pipe with adjustable header works really good with great runtimes. Alot of people said the JP-1 and 2 worked really good too.
Avg. engine temps usually run around 200...yes I said 200. None of mine ever ran more than 230 on extremely hot days.
I had 2 621T's that had over 8 gal. each on them...very good engines. I think they are being sold in the U.S. by their proper name again....OPS. I heard TKO was distributing them now.

thanks for responses. i have jp1 and 2. should i look for jp3? i had one in the past and was not impressed with it on a v-spec. .... yes tko has them on their website under ops. they have a crazy looking green head. i wonder what has been changed on the new ops vs. the radical? evrything i hear about the new engine is positive. supposed to be stupid fast?

They are screamers fo sho....really smooth and more power than you can stand. I've actually heard through the vine that the interals look even better and cleaner than they did under the Radical name.
