I wonder how much of the top end gains were just the larger throttle body? It would be interesting to see if a 90mm plus throttle could be grafted to the truck intake? Maybe even a slight bore out of the manifold opening? Might be much closer then to the LSXR top end power figures?

Thanks for the info in the video, I thought the article was where the info was.

Could you provide access to the Comparison data for the various truck manifolds? I understand that FAST probably volunteered the manifolds and perhaps gave you some funding. I am trying to work on a budget that is lower than $3000-4000 for the fuel whole system, and I have most of the parts except the intake manifold, fuel rails and injectors. I tried to order the FAST intake fuel kit, but a year later it still never came... I have changed the tact per a local tuner suggestion and I am trying to go with changing just the intake manifold, fuel rails and injectors. But the fuel rails may not change from my 1999 Chevy LS extended cab 4x4 truck.

It's not budget, it's C.A.R.B. actually preventing us from going overboard on tuning our cars and trucks!

I thought this was going to be a comparison of different intake manifolds, not just stock truck and the fast. Disappointing
