Evening folks,
ChefTA here. I was wondering if anyone had any insight or first hand impressions of the RAPTR cam by Thunder Racing.
I like the cam profile, and it sounds pretty good.
I was wondering if it was too small or would make a good cam for the 415 I'm building. Youtube has a lot of neat videos showcasing its idle, and different exhaust variations.
Maybe a Thunder Racing rep on here could chime in for info on this cam.

Thanks. I spoke to Thunder Racing rep today, and said for my build, and power that I'll be making; that its better to go with their
STROKR V.3 - 247/251 - .624/.632 - 112 lsa - 2400-7000 RPM
I'd still be open to videos with large cubed LSX motors.

Mine is a regular ol LS1 with a RapTr cam, and I really like it. Wish I could give you input on what you are looking for, but I would def. go with what TR is telling you.

KevinR, how is the driveability of the car after the cam? Before and after tune.

I had to drive the car for about a week before I could get it tuned, and it wasn't too bad. However, I did already have somewhat of a tune in it already because I orginally had a trex in the car (which didn't work). Cold start was a pita prior to the tune being finished, but once it was started, it wasn't too bad. The guy that tuned my car is really good, and he got all the bugs worked out for me, so driveabililty after the tune is not bad at all.
