WCCH, heads, intake, untuned results...
Some of you know I swapped a set of WCCH LS7 Stage II heads onto my otherwise stock LS7 with AHR longtubes and KBII intake.
Having some issues with HP Tuners so I was unable to tune the car so this is just a base line pull the car was running fairly rich at WOT but I think it's about dead on.
Before the WCCH head install dyno numbers:
474 rwhp / 469 rwtq
After the WCCH head install dyno numbers with zero tuning:
505 rwhp / 480 rwtq
SAME DYNO.
30 rwhp gain and 20 rwtq AND my engine doesn't blow up when I rag on my car? I'll take it
On another note my stock motor'ed E85 powered Buick T-type with a TE60 Turbo and FMIC made:
485 rwhp / 568 rwtq on 31PSI Can't wait till I put the big motor/turbo combo in early next year!

I went ahead and put you on the "PUP" list. (Physically Unable to Pop due to a broken stock exhaust valve) List

How much were your heads milled?
I'm curious what gains, if any, are had on stock manifolds and intake with WCCH stage II heads. I have WCCH stage II heads on an otherwise completely stock motor, and I only had surface milling done on mine so I don't expect any significant change in my CR. I didn't notice any SOTP difference at all after installation. I will be doing a tune to take full advantage of the WCCH heads, of course I did the heads for post-warranty reasons more so than the performance.
Anyway nice gains.

Definitely a fringe benefit.

Nice gains. How were the power power pickups under the curve?

Funny you should ask...
I was able to drop by the shop and build a before/after dyno comparison and I've updated my DIY thread to show the dyno results.
