Default ***biggest numbers out of twin s366's***

What's the best numbers that you know of on a ***** to the walls pair of s366's? I'm putting a set on a 403ci LS2 and the motor can spin 7000rpm and see about 30psi. I think I could actually max these turbos out... but what have you guys seen to the wheels with these? Thanks in advance

I saw a thread where a guy made like 737rwhp on 12psi on a 6 liter. I know several people have similar setups and I haven't seen one person throwing any boost at it

I dont think your ls2 will hold that 30psi you plan on chucking at it unless you have oring gaskets.

Im halfway through a similar build. Lq9 403ci 11.5:1 comp ls3 heads twin s366 and a powerglide. Plan on pushing 20-22 psi. Maybe more if it feels strong

Ive been using a pair of s366's for a few years now on my 5.3
Only dynod it once 14psi made 685whp
I run 26psi at the track, and has pushed 3250 lbs to 161 mph. My combo is not an optimized race car.

The fastest guy I know that used them was Seth temple, he works for bw air werks and ran low 5s at 140+ in the eighth.

I plan to push 30psi on mine when builds done. 1200+rwhp I'm looking for thru th400. 6.0l or a iron 5.7. Not sure yet. On an ideal setup all working together they should be good to near 1500 on a 6.0 or less cube.

Certainly do have a good tuner mate. Running it on e85. Plenty of very similar builds getting around in aus no worries at all

That's good because 11.5:1 and a lot of boost is a delicate situation.
