Anyone have experience twin 6262s on a 6.0, with the .68 a/r housings?

i'm a fan of "under turboing" street cars, wondering where's i'll run into the limit with these turbos. low and mid should be amazing, wondering how they keep up on the backside.

Unreal

Depending on power goals I wouldn't go that big. Billet 58s are my choice on a 6.2L after driving just about every combo. Unless you can go for EFRs, then do the baller EFRs.

power goal would 750-850ish whp, with a possible infamous 1000 glory pull if all the moons align in the future

Unreal

I would go smaller, but that is me.

I agree with Unreal I'd go with 5862 turbos with 6.0 specially with Roll Mexico runs you're doing.
Quick Spool and you will NOT max out before 900-1000rwhp.
BUT If you're planning for bigger motor later that's a different case.
A friend of mine ran with TTix on his 6.0 C6 Made over 10xxrwhp with 6Speed / Low 900rwhp Powerglide ran 8.5@158mph

Correct.. Go 5858max and that will make way more than your goals.
Might even try smaller for 750-800

Unreal

Billet 5457s is what I would run for those goals.

Anyone have a dyno sheet for those smaller turbos?

only thing I came across with smaller was turbo-geist ttix FRC.
ttix 57mm @ 17psi LS1/241, cam setup.

and this stock LS2 GTO with PT6262s. looks like vband housing, so should be .81 a/r

granted there's some apples to oranges here. since ones at 17psi vs 12
it's seem they're both awake around 4k with the 57s, with the 6262s carry it better on the top side, with the stock cam. though i dont know what a/r are the ttix 57s
