Re: Throttle body help ?
Are you thinking about upgrading the stock one from a 48mm to 52mm or purchasing an aftermarket one?

I would have to say worry about the biggest bottle kneck of the motor first.. which If I had to guess would be the 2 inch inlet of the stock upper intercooler

True, but they leak, so I was trying to figure out what he's thinking. I would have Matt upgrade it simply to resolve the leak issue, but since he's in there you might as well have it ported. :2cents:

I totally agree.. if your going to send it out to have it fixed then why not have it bored out to 52mm for a few dollars more

Re: Throttle body help ?
shaft will leak because its metal to metal. The guy puts a bearing in there and opens it up to 52mm. I noticed a small increase in performance, Not worth it on a stock truck unless you have a vac problem like I had. Eventualy all stock TB will develope a leak.
the guys name Matt blum think this is his e-mail mjb_machine@yahoo.com
and his number 1-402-740-7663
Think Chris knows him well.

Re: Throttle body help ?
So there are no aftermarket setups available? I run a 58mm one on my LT1 and the stocker is 48mm like ours. I would think the turbo setup would need as large or LARGER with all the air being forced through it?! ---

Re: Throttle body help ?
No, there isn't an aftermarket one that will work with our factory plenum since its opening is only 52mm. If there's one available you would have to machine the plenum openings larger. When upgrading my stocker I asked Matt about how big we could go and he said the largest you could machine the factory T/B would be 53.5mm, and that is pushing the edge of safe, even that size has a tendency to crack. That's why he stays safe with 52mm.
Another alternative is going with the a Edlebrock intake, a aftermarket 90* elbow, and whatever T/B that works with that setup.

Re: Throttle body help ?
remember syty's have horrible idle from the factory.. the later revision to the ty chip helped alittle more though but still wouldn't be silky smoothe like some cars
Here's the bike tube test to see exactly how bad of a vacuum leak you have in the blades
