PRC 215's , Tsunami ,RPM-Ported FAST 90/90-base results... First off I would like to thank the guys at TSP for giving us the opportunity to be the first to test their new PRC 215 cylinder heads. I got the heads in about two weaks ago and finished up the install last week. We were curious to see what they would do with the current mods that I already had. So the #'s I am posting are with Pacesetter 1 3/4" LT's with Pacesetter Y-pipe. I have switched to TSP 1 7/8" with a TSP y-pipe. Due to the weather here I have not been able to get the car back for new #'s with these headers. Just to note also I was waiting on the new headers to install 42# injectors so all this was done on the stock fuel sytem. Needless to say we were very happy with the results and are shooting for better #'s with the new headers, injectors and a cutout. So here is a run down of the installed parts for this graph ...
1998 WS6 M6 (my daily driver )
Stock LS1 80K
Stock Gears
18" Wheels
PRC 215's (60cc)
PRC .660" springs
TSP Tsunami Cam 111 lsa
TSP 7.500 .080 wall 5/16" pushrods
Cometic head gaskets
ARP Bolts (head)
LS7 lifters
RPM ported FAST 90/90
MSD wires-NGK TR 55's
Pacesetter 1 3/4" LT's
Magnaflow Catback(no cutout)
Pacesetter y pipe
Stock Rockers, WP, Rearend
RPM SD Tune
Injectors way past 100%!!!!
note this did not require fly cutting
This package was designed to the be the ultimate no valve-relief heads cam combo available, & it truely didn't disappoint! A cutout & injector upgrade & $400 1 7/8" should be all it takes to be right at 500rwhp!!

Looks nice, Jason! She should be up close to 495-500rwhp once the new headers are on and you have enough injector in there!

Nice looking curves. So how big is the Tsunami cam? I'm wondering how generous the P to V is in this combo. Fantastic results. 
edit: I see the specs on the TSP website: 235/240, .654"/.609" 111LSA
