How much difference would it make getting a larger throttle body(85 or 90mm), vs just porting and polishing the stock throttle body? I found 85 and 90mm throttle bodies for sale on a site at $500(same price on both). Thats $500, or I think there's a guy here in the Dallas/Ft. Worth area who will port and polish mine for under $100. Anyone know said guy btw? Lost his contact info.
Unless you're going to be adding headers and hi-flow cats, the larger throttle body really isn't going to help much. Rule of thumb: Larger in, larger out. 85mm is about the largest you can go with a stock tune.
If the goal was to get more power, I think your money should go down a different path.
So I have a stock 6.1 intake. Are you all saying I can see a boost usit it with a 90 mm throttle body. I have ARH headers and hi flow cats and a borla catback. Also a homemade real cai and a 180 tstat.
He's done hundreds of these including mine. Absolutely beautiful work and about $100 if you're associated with the DFW LX crew.
It's worth $100 but certainly not $500. I can barely tell the difference but the throttle response is better. Looks a heck of a lot better than stock but you won't see that part unless you take it apart or remove your CAI. Takes about 90 minutes and he'll do it while you wait. Very cool and he's a great guy.
You can PM me for his contact info.
The answer to "ported" or "bigger" is: ported will give you a bit on a relatively stock or mildly modded engine (exhaust, Predator). A bigger TB will be necessary as you get into big money power adders. At about that point you'll want to be working with the full time pro's like Andy at PWR. Hope that answers it definitively for you.
