So how much power will I be giving up by running a 52mm TB w/ 38 lb injectors with a LE2 383 over a 58mm. I know lloyd recommends a 58, but I've got a good deal on an AS&M 52.

 

I'm not sure I'd like to know to though.

 

Imho no loss.

If you figure the VE and your max rpm.....I bet the stock one has plenty of CFM airflow to work fine.

But then again...I have never seen a h.p. gain from a bigger TB. Even changing one while on the dyno....never sean anything. Other than making more h.p I don't see a point in it. Maybe it drives better. A 52mm should work fine.....I bet you if you stick it on a dyno and swap a 58 back to back you will not find a gain

 

You beat me to it! I agree 52 is probably more than big enough for 90% of modded LT1's/

But I'd probably in line for one if someone came out with a 60mm tb for lt1s

 

yep, even though I will never need it....I just went to a 1200cfm on a vic intake. oh well

 

Bigger always seems better!

 

Thanks guys
