Twin Turbo Sizing

NoSlow6.0 · Apr 26, 2013

Right now I'm running a single 71 turbo on my race truck but I'm having to spray the heck out if it to clean up the smoke. Seeing as how NOS is pretty hard on enternials I'm wanting to go with twins. What size has everybody found as best for 295's and around 1,000 rwhp. I'm wanting to build it all myself but need advice on turbo's. Thanks.

A 62 or 64 HP and a S480 on top... not sure if that is 1000hp capable or not though.

I think they're probably going to say a 66mm secondary with an 82-88mm primary.

How much is a nice twin kit like that?

Mdub707 · Apr 26, 2013

Yeah I think you're right Garrett, the 80 might not be enough for the 1000hp mark. I think Ellerton stepped his up to an S510 last I knew....

seems like most of the guys making 1000 or more are still spraying quite a bit. Probably just crappy head flow on these 6.0's.

were going to be putting a 66 and a 480 on the red truck...down the road may switch out the 480 with an 88..... not sure its 1000 capable though

Twins or compounds

TooMuch03 · Apr 26, 2013

an S480 is not really 1000 hp cabable. I would go with a 66 and S488, or better yet, an 88mm GTX charger.

Mdub707 · Apr 26, 2013

Is it the 80mm that's not 1000hp capable, or is it the 80mm attached to the 6.0 that's not 1000hp capable?

You could probably touch a 1000hp with ease with the 80 as the LP, with some spray! :thumbsup:

Could try *****'s new 80mm....

(Copied from another forum...)

In the first dyno flog of the newest design Billet 80mm compressor wheel from ************* for the S400 turbo, a 249 rear wheel horsepower gain was realized in comparative testing against the cast 80mm wheel.

Cast wheel made 1040 with the gate pinned shut making 23-24 psi. Billet wheel made 1289/1107 @ 29 psi with the gate pinned shut.

Both turbos had the 96/1.32 hotside. A 1.58 housing will be tested shortly.
