All spacers on the market are designed for the inner bore of a stock throttle body, however there is 1 spacer on the market from a small Canadian company called MiR Performance that has their bore designed to work with BBK throttle body upgrades.
Here's a link to their website - > MiR...
Hey guys, I was thinking of possibly designing a spacer that will make the Gt 80mm butterfly clear the stock silencing fins as well as orientate the throttle body to clear the thermostat housing etc. If I made a spacer and hardware kit available to just buy and bolt on it would make this mod...
If you got supersixmotorsports ported upper and lower intake manifolds you definitely need a tune. I have ported quite a few 3.7 upper and lower manifolds myself as well with great results. After porting I got a custom dyno tune done, and I highly recommend you at least call your canned tuner...
This is a REALLY good idea! Great way to do a cost effective throttle body upgrade. Wonder how much of a demand there would be for this? Should do a poll and find out interest.
From the measurements sandeale did on the bolt patterns it wouldn't make sense to put it on the stock manifold as the bolt pattern is wider so the plate you'd have to make to attach it would bottle neck the gt350 throttle body likely and make any possible gains almost unmeasurable.
Considering the gt350 throttle body is so cheap and larger than the stock one I think it would be nonsense doing anything otherwise. I agree MaskedRacerX
Considering there is more clearance above the engine in the 2011-2014 models as well as the majority of engine changes are internal I would assume it would fit just as well and function. Physically the heads are the same the only differences are port size (minimal) and cams, which give more...
Boosted cars run richer under high loads and throttle because it can do serious harm if it leans out at all. Not only that but boosted engines run cooler from a rich mixture as the fuel helps cool the intake charge, which also helps produce more power. Running closer to lean would make more but...
Thanks again for putting your money and car on the line to test this out! You kick ass and are now responsible for my bank account getting slammed with an intake and throttle body order! :cheers:
Honestly I bet this gt350 intake is better everywhere than any of the current intakes on the market. It's their latest and greatest. That IM and the throttle body I wouldn't be surprised to see 30hp and 30tq at the wheels gain over stock with a tune. Mark my words because I think I'll be close!
