twin setups on ls1's
 

What are guys running on 346 setups....... twin 67's? just trying to get some ideas on what is too much or not enough, spooling issues etc...

70s worked for me great... the lag was perfect traction control.

great comment lol :devil:

Twin s366 borg warners here.
Not up and running, but they will support over 700RWP each, so I've got plenty of headroom.
+1 on Tiago's traction control idea, I'm hoping they come on a little slow!

Nickj Yoskin's TT vette used to run 67's. its spooled pretty quick on stock cubes! His has since gone to a 427 that is unreal! lol

so yeah 67 should be ok. and dont forget big turbos produce cooler air..... ;)

I could have swore he had TE44's on his first setup and now with his 427ci he is running twin 66's...

If I were to build a twin 348ci LS1 and looking to keep things together I would run twin 58 to 62mm turbos. You will benefit from quicker spool and still be able to make over 1000rwhp at will...

VINCE you might have been right mate. he has changed the car soo much over the past few years i have lots track! lol

how about a pair of Garrett GT35r's?? work amazing on 402's and should do VERY well on a stock cube motor!! :)

It depends where you're running the car. Are you all street, street and some strip, or all strip? My car was a street car and I ran a 6.0L 364 with twin T61s. They came on at 3800. Stay with these or smaller for good street manners or go bigger for strip stuff but you will have much more lag.
