pretty impressed with the tbss intake!
So was I! The lsxrt proved itself up top but only about 4 more hp average. Still proved lsxrt is best for these like Matt has been say/proving.

If the SS intake wasn't so damn ugly more people would probably keep it. The Fast is still low bang for the buck IMO. And I don't think anybody is actually running the MSD except for testing.

Porting my Mid-Rise right now... being boosted it isn't going to change the results much. But, it makes me feel better knowing all the casting flash is gone.

I have bin messing with the stock ttss intake now for a few days.
The front part behind the TB is a big choke point..........
It will be 3.5"all the way to the box here soon...........

I'm surprised at how the Edelbrock performed. I figured it would have been the worst.

The ProFlo was my second choice due to the smaller tapered runners and good plenum volume. It only has a bad reputation due to a lack of experience... like most products.

Other than the cam and heads being a bit hotter than most normal builds, this is a pretty good indicator of the power potential of the intakes. Now if we took all of these and ran them on a milder 450hp street engine with a more reasonable 6500rpm rev limit the overall impact from manifold to manifold would be less impressive.

Regardless, it is nice to see actual results and not a bunch of unsubstantiated opinion and conjecture.

I agree, some of the differences would be minimal at best in a lower hp build. I'm also curious what difference the throttle body made in the results. They used several for the testing and that alone will change flow numbers.
