Intake manifold question.

[Fusion Training Systems]

Have a 21GT 10R80 and soon adding a ESS G3.

Curious if I should stick with my stock IM or run a boss?
ported or non?

I’ve talked to 7-8 guys at the track (drag strip) and read several threads who all run different manifolds with their setup and curious which is optimal?

Thanks

Stock but get rid of the IMRCs

18 and up is really good. The GT350 is supposed to be a TAD bit better, but you have to ask yourself if the juice is worth the squeeze.

If you want more power, pulley down…

Stuck with the on you have lock out the imrc and SEND IT

Why? IMRC on the coyote does nothing to rob power

"Some" say they can close or slightly close under boosted applications. I prefer them gone, easier to tune that way.

Most tuners will lock them out in the tune with centri/turbo setups.

Keep stock manifold. 18+ factory manifolds are pretty solid even NA and the differences in manifolds are less apparent under boost
