ETP 215* H/C results - Pictures These are the preliminary results. I have some valve instability around 6300 rpm and then it gets bad after 6500 rpm. It's probably costing me some peak power. It looks like I should have shimed the valve springs. This cam should pull all the way up to 6800 with no problem and the torque comes on early with 344.6 at 2600 rpm. These results are with a stock pulley, water pump, through the cats, and a crappy Vararam foam filter.
STD
SAE Comparison when I brought the car in for a baseline before the h/c install. My old setup was a 225/225 113 lsa.
I have another graph with a higher peak hp but lower tq.

The cam specs were 224/236 63x/595.. 115lsa? what was the ICL? Was the intake lobe a LSK lobe? What was your final compression ratio? Great numbers regardless.

Very nice. Very nice. Get those springs under control and you've got a killer setup.
Very nice peak tq figure. Congrats.
So, you've got a 224/234 cam with .637 lift? Is that an LSK grind on the intake?

It's basically a 224 LSK intake lobe and a XER 236 exhaust lobe on a 115 lsa retarded 2 degrees. The heads have a 62cc chamber and I used a stock mls gasket.
I'm going to get a better filter, remove the cats, add a pulley, shim the springs, and see what it will make then.

Gotta love those LSK lobes. Great power everywhere!
