AS&M 54mm TB... the best of both worlds.

 

I tried a friend's 58mm TB last yr. It seemed to have less throttle response than the 52mm. Which produces more hp? Dunno.

 

52 is more then enough

 

close to same setup going with holley 58mm... i was told my lloyd that if i wanna get the most outta my heads cam car 30# injectors and a 58mm tb is what i want

 

unless you are pushing some serious hp 500+ stay with stock

i oull 122mph threw the traps on a stock tb

 

yeah.....I wouldn't go no more than a 52mm. I was told by Holley that the 52 would be more than enough for my set-up as well.

Hey Banester. I think you should drop down to a 40mm you backwards ****.

 

stick with the 52 unless your going to go big (>450hp or >350cu in). denny will be the first to come up with the break point i bet i bet....

I'm gonna try anyway.

Just ordered all the parts to redo my bottom end a couple of weeks ago with everything getting balanced this week and am working of a set of new heads. As soon as eveything is together, I'll take the combo to the dyno and do final tuning. Once tuned, I'll borrow a 58 TB and see what happens.

I've learned to be conservative in my estimates but have made as much as 466 rwhp in the past with other combo's. I expect this one to be anywere between 425 rwhp to perhaps as high as 450+. Whatever..... ??

This TB thing with everyone guessing needs some real answers. Screw this theory stuff...... it where the rubber hits the road that counts.

I've owned a stock 48, 52, 58 and a monoblade and don't know if any of them made a tinkers damn of a difference. As mentioned, going to a 58 from a stock 48 on a car making 331 rwhp made no difference.

The 466 rwhp run was with a 58 mm TB. Went to the monoblade and ran into other problems throwing everything off or I've have an exact answer on that one.
