Does anybody have or run on3 turbo kits anymore?

so basically my tuner is being an *** and saying my on3 78/76 turbo wont make any more power than the current 564rwhp on about 16-17 psi on my fbody.

Mods are:
4.8 w/ 100k
btr stage 2 turbo cam
ls6 intake
862 heads
prc .650 springs
on3 turbo kit
built 4l60e
ptc 3800 stall

but found out on the dyno from last time i had an exhaust leak at my driver side manifold from the bolt closest to the coolant temp sensor not being in at all. could that affect power and tuning?

That's hilarious. I made more power than that on my LQ4 with the on3 7665 on less boost. Granted, our combos are vastly different and dynos are a tuning tool, but it should definitely make more power than that. Run it at the track and see what it does.

Too many factors could cause the low numbers. Take it to the track and see what it does before you go slapping new parts on it.

Also i do believe the car is a 9 second car if i put tires on it. I ran a friend with a 2015 5.0 rousch and 1 lst roll race i spun and let off..2nd from a 70 roll we were neck and neck. He his on stage 3 on his rousch setup and making 707 hp to the crank compared to my 650

ON3 78/75 is a great turbo. Take to the drag strip and tune to MPH/ET, not big HP.

What kind of mods does he have? Those things run 11s with drag radials.

If you were even from a roll I bet you could crush him at the track.

My 5.3/s474 only made about 490hp @16psi on a Mustang dyno but still ran 135mph which calculates to something like 600whp. Go run her!
