Well today I broke out the GRP after the case on my Vspec cracked. I had broken in the GRP on a bench, and had it in my pit bag ready to go-pipe-clutch-already installed, ran 1 qualifier and a 20 minute main.

Running a JP3 pipe had 1/2 a talk after 5 minute quali, impressed how smooth the engine is, yes doesn't scream like the others but has power where it counts, maybe still hasn't completly broken in, but compared to my EB Mod Vspec doesn't have the same top end, nevertheless still very pleased, going to try the GRP pipe 2053, maybe I can gain a little more top speed. Temps consistent 189, nice trail of smoke, idled forever, only change I made is went to a GRP4 instead of the 6 I broke it in with......time will tell...(I got 8 gal on my VSpec).
