bigger throttle body??????? at what rwhp would you need a bigger tb? I have a stock polished tb on my motor, but would i benefit from a larger tb? I am running 28 lb injectors and they are maxed out but are working fine, no need for larger injectors. my mods are in sig.

Its a stock ls1 rebuild short block. and i do have a professional products intake. car is a 2000 ta. Also, the reason i was wondering about the larger tb because i knew if i went with one like a 85 i knew i was going to buy larger injectors too. That is why i am asking so i would know if it was worth the expence of tb and inj. . my current a/f ratio is 12.8 at wot right now.

You could try an 85mm but you would probably be better off selling what you have and grabbing a used Fast 78, 90, or 92 intake and getting the tb for that.
Might be 10rwhp to gain on a setup like yours unless the PP intake is better than I'm aware.

I was talking about a gain from switching intakes. I doubt you would see any gain from the throttle body alone which would show up on the dyno.
Injectors are not a HP issues, they are a longevity issue. Overworking their duty cycle can cause them to fail.

I would do a FAST 92/92 setup.

People keep talking them (PP) down but I have yet to see
one straight up comparo other than the vendor's own
put-up vs a LS6. You got anything besides speculation,
hearsay and "probably"? Because so far it hasn't come
around here.

We found that from TESTING way back, the LS6 stock intake is equal to the PP aftermarket intake on the dyno.
We do sell the PP intake and TBs because there are some who want them.
If it's when the injectors are maxed out at WOT with the air/fuel ratio optimized.
