LS2 GTO/V.2 Polluter/PRC As cast 225cc/Fast 92 makes 500rwhp!!!
This customer is a friend of several of our customers and decided to bring his car to us for a head/cam/intake package which included our brand new V.2 Polluter camshaft. This customer opted for the 111LSA version, PRC As Cast 225cc cylinder heads and a black Fast 92mm intake manifold. We also installed a set of Kooks 1x7/8" headers and off road connection pipes to complete his exhaust modifications. Along with the exhaust a Vararam intake was installed and we opted to go SD on this one to get every last ounce of power out of it, and boy did we ever!
List of modifications:
Stock LS2 6.0 bottom end
PRC 225cc "As Cast" cylinder heads with 62cc chambers 11.47:1 SCR
Tick Performance V.2 Polluter camshaft 239/244 .62x/.59x 111+2 (Proves you don't need LSK and XE-R lobes to make BIG power!!!)
Fast 92mm intake with stock LS2 90mm TB(unported)
Kooks 1x7/8" headers and off-road connection pipes
Corsa Cat-back exhaust
Vararam intake
SD tuned on 93 octane pump gas
Idle Clip of camshaft:
I know some will say, how's the P to V with the 62cc chambers? It's fine in short. The "As Cast" PRC heads are cast with a 62cc chamber so no milling is required to achieve this chamber volume. Thus valve drop remains unaffected. Since they are a 13* valve angle head the valve drop is also greater than stock so you get great compression, room to run a big camshaft and big power is the result to put it bluntly.

I was hoping the torque would hit 400rwtq a little sooner, but I'm very pleased with the power output overall!

Aaron, like I said it's your special touch that did it! We will be buying more sets of these very soon.
A fourth gen F-body? Probably a few numbers better, not much though.
I love the torque as well especially how well the power carries. Torque is over 400rwtq from 4,000rpm all the way to 6500rpm and as you said 500rwhp from 5900 to 7000rpm.
Of course the internet experts will tell you that big cams can't make big torque or great average power.
I am very happy with this cylinder heads performance. After seeing Carter01's results on a Mustang Dyno with a single plane intake and small 232/234 cam I knew these were going to make some good power on this set-up as well. We all were expecting 470+ from this combo, but honestly never expected 500rwhp. It was a pleasant surprise to say the least.
Yes that they are.
Thanks Chris, means a lot coming from the 520rwhp stock bottom end king!!!

This thing is a monster though. From 4000rpm on up I've never felt a stock stroke N/A engine pull this hard. Normally with a stock stroke engine, when I shift and the rpm's drop it takes a second for the g-forces to climb again and put you back in the seat. This car even at the very bottom of its shift extension is pulling nearly as hard as it does up top. Very pleased with it as it's anything but a slug down low and not just a top end screamer.
