Remind me what ECU your running?

As quiet as this section of the forum is, I am glad I am not the only one still wrenching and not driving this summer.
Glad to see the milestone on your end.

Video!

the blower sounds real loud in the video, but it reality the exhaust is about the same sound level

also a set back today
the welds on my 32spline stub axles didn't hold!
The need to be rewelded
actually they should have been pinned.
drill a hole now will not be fun as the material is hardened.

Initial tuning is done.

He wants to get some more done before taking it to the dyno

Did you keep it an s trim or go to the t trim? Also are you running it at max impeller speed or lower? Awesome to see this come together

Going to see what it makes with the S for now.

The ratio is still set the way I bought it from you.

Drove the car today!


If it was for the inspection sticker, which it's getting tomorrow, I would have took it home

Need to break in the clutch, 500 miles, before he sticks it on the dyno.

Except for the clutch effort, it drove just like a stocker.

Need to keep it off boost till he dials it in.

with that, it pulls real strong.


Need to get the shock canisters recharged, moved them inside under the hatch.

Congrats Brian. I know how those long-term projects can wear on you. As you drive your car, it'll make it all worthwhile. I'm planning on driving mine from Florida to Carlisle this month, IF I can get everything done with it that I need to!

Enjoy that Corvette but remember how long it took you to get to this point. Don't feel you need to use it all up the first week you get it out on the open road.

Have fun!

made a run this weekend with a friend to break the clutch in.



after Panuche's we drove out to Hampton beach.

Boost gauge location is perfect.

Street twin clutch worked like a charm.

26mph on the highway

pulls plenty hard even keeping it off boost
