Largest T6 Turbo for Stock Cubes What's the largest T6 turbo one can use for stock cubes forged LS1 engine without too much lag? No limit on HP or fuel except head lifting the 4-bolt heads.
What's resonable spool time for street/strip A4 car with 3400 stall? 3000, 3500 or 4000 rpm?
Trying to choose a one turbo that will work on stock cubes and future upgraded motor 408ci.
What can be done to help spooling a turbo? Can the boost contoller be used in any way to help spool the turbo quicker?
I know.

You could try the "quick spool valve" but no matter what a t6 turbo is going to be somewhat laggy on a 347. A good boost controller can add pressure to the top of the wastegate to keep it closed during spool up, but it only helps marginally.

You can do a 101mm+ Thumper on a 346 LS1.
The Ford guys have been doing it on 302's for a long time.
Is it ideal? No. Can it be made to work? Yes. Spool up will be slow unless the proper steps are taken. Boost controllers with CO2 systems to help keep the gate closed and such. Tunes up plays a big factor.
Being you are planning a bigger cube engine later that will make use of the bigger snail, screw it and slap a thumper on the 346. Play with it till your big cube motor is ready. Then have fun.

Problem is I've seen some 6-cylinder Japanese car with big turbo but it will never spool without a nitrous shot at the begining to spool the big turbo.
So, is 88 or 91mm T6 too big for stock cube LS1?

I think it will preform on the track no problem, the thing your going to have to worry about is the street useage and how important it is to you. Automatics help with the converter and the small rpm drop on a shift, but that does not mean it is not going to be lazy and torqueless downlow.
This is about the route I'm looking at taking. Fresh forged stock cube motor, and thinking about going with methanol and a large frame turbo. Would love to hear more feedback on this subject.
