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!

 

Very nice !!

 

nice numbers!!

 

Those numbers are very good

 

...video pls!!

 

Whats teh duration on that cam?

 

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

 

Nice numbers.
