Twin turbo chassis dyno tests

[jschwartz]

Here's a link to some vid of dyno testing that took place yesterday for an upcoming TV show.
This is my GTR twin turbo 6.0L LS2 at just about 17 lbs boost.
For reference it makes 1003 hp on the engine dyno.
You can see on the 1st test she's really moving some air.

Jeff, that is amazing. Well done on some spectacular engineering. I can't wait to see the fully tuned car at this year's US Ultima gathering.

The Silver State Classic Challenge is September 13-16. Jeff will confirm, but I believe he will be motoring out to Nevada for that.

Maybe it's time we start thinking about some dates and locations for the US Ultima Gathering. Ed mentioned he's looking into a track day at Indy!

Awesome! Yeah I laughed out loud when those banners blew off the wall! I hope we do get a gathering together this year. I saw it at last year's gathering, but am hoping for a ride at this years. (wink) It was crazy before with the old motor. I can't imagine what it feels like now!

I would consider it a real shame if we don't do a meet this year somewhere. I will be taking the GTR to Monteray in August. Dantia and I always heve dinner on Saturday night with the R5 turbo boys we could certainly expand the list to include some Ultima folks. lee

Is it not amazing that the torque that motor is putting out nearly bottoms out the rear suspension?

Do you have photos of your half shafts?

Stunning that the transaxle can stand that much power. Great job.

[ultimad]

Yeah - what transaxle does it have in there ?

[gtr-gaz]

Nice motor Jeff

Just out of curiosity, if I were to build a Canam in the next year or two, how much would it cost to put that setup in it?

[chuntington101]

amazing work! have you got the dyno sheets??? be nice to see just how quick the boost comes in. not that its going to be a masive problem with the light ultima!
