Twin Turbo C7 Corvette Dyno Results - C7Z06- 1277whp

Finally got the TT-C7z on the Dyno last week! 1277whp @ only 22psi is just crazy for this setup

We were very anxious to get this thing on the Dyno after the half mile event just to see where we were at. We changed the wastegate springs for more base boost and resolution on the controller before hand.

1st pull was ~ 950whp @ 15 psi. Base boost/ wastegate spring.
2nd pull was 1174 @ 17 psi
3rd pull was 1194 @ 19 psi
4th pull was 1277 @ 22 psi. (65% DC on the e-boost vs 100% prior)

These Turbo's are very high pressure oriented and I believe there is much more left on the table before they are maxed out on the exhaust side. Considering the stock block, trans. We decided that's more than enough!

We've logged almost 3k street miles on this setup. 13+ passes at the half mile, and now 5+ Dyno pulls at max effort with little more then an oil change and plug ✅. Driven +45 miles to Dyno each way in the Texas heat!

This car drives like stock with absolutely no compromises to anything whatsoever. No loose converters or hassles with ground clearance and sump pumps, it's just simple stuff that works like it should. No tricks or gimmicks. K.I.S.S.

We have a few more setups in the works at the moment, combined with much larger turbos and displacement, we expect some ludicrous numbers to follow 😎
