New twin scroll turbos? Options

[awd4kicks]

I've heard a rumor that twin scroll Garret GT ball bearing turbos are or will be coming out in the GT35 and GT42 sizes. Does anyone have more info on this or a web link? Sounds very interesting to make a 35R or GT42 spool up quickly... Almost dangerous.

Is this the same set-up that we watched you dyno over 800HP with Darryl? If memory serves me right you weren't seing the real power until the high 7000 RPM area.

Yes and no.

Since then we put in Brian Crower 280 cams, much better intercooler and most importantly the cams were not degreed in. The head we're using has been shaved a few times and who knows what else has changed, but anyway both of the cams we're retarded to what seems to be about 4 degrees. At the Michigan Nopi event the turbo spooled about 1600 rpms sooner!! The first pass I came out of the hole easy expecting to bog and the car just dead hooked and pulled a 1.400
60'. The car hit 40 psi in 1st gear! It had never done this. The next pass gentle out of the hole and the same thing 1.403 60'. The rest of those runs had some electrical/fuel pressure issues. Lately the car has been running 10.1-10.9 with the car not running at the 1/8 mile and coasting through the 1/4 mile trap between 96 and 110.

So forget what you saw on the dyno everything was messed up then. Our best run to date was 9.2@160.65 and we hit 127 in the 1/8th. The 60' was horrible and this was before the cam timing correction. The new IC net only a 10 degree temp increase during the 1/4 versus the old one it rose 50 to 80 degrees. Hopefully the next time out the issues are resolved and we can see some real ET's.
