110 WRHP Gain after VVT Cam and Hand Ported Stock Heads on my full bolt-on's 2013 SS L99! Here is a idle clip and dyno graph.

Nice Terry!!!

Excellent numbers. It appears 500rwhp is becoming the norm for a well thought out motor. I like the torque and horsepower curves. Looks like it could have hung on for a couple hundred more rpm. What octane gasoline are you using?

Awesome thanks for sharing the video Terry.

It will go to 7000+ no problem!

Shell 93 octane.

Any new track times ?

Camarojt · 03-22-2014, 06:54 PM

Nice sound at idle! Torque is staying up for a good ways!! Good job!

"It will go to 7000+ no problem!

No doubt about the 7000rpm number. Reason I asked about the octane is I don't think I can get 500rwhp on California 91 octane. Those that are getting the 500rwhp number are probably like yours and using 93 octane.

Correct. Timing difference from 91 to 93 is surprising.

Impressive sir! My next performance MOD was getting my heads ported and you just helped convince me. Did you the heads ported locally or send them off?

rich3fan · 03-22-2014, 08:11 PM

Granny shifters FTW!!!

Congrats on your numbers!

Smoky · 03-22-2014, 08:18 PM

Awesome numbers, looking forward to my SS3 install. I do believe I will take a stab at hand porting the heads myself as well. I can only hope for such numbers. Sounds great!

axis · 03-22-2014, 08:23 PM

That is a strong bolt on only car as well.
