Ported Stock IM by STM or Driven Innovations intake manifold? Running stock turbo, E85, and goals are stock turbo record. Just want to here some thoughts before i cause myself more work and get to do the whole IM install all over. Is it worth it. Car is strictly for drag racing and ocassional cruise on a nice day. Im just wondering if ill give up to much down low for the gains up top. I might just run both and tune them both and see the differences. thanks.

 

Chris Cessna made 700whp using an STM ported intake mani. That alone says something. For a stock turbo application I don't think there's anything better to go with.

 

Yea, thats what i keep thinking and is probably the best solution, but for some reason i keep coming back to the idea of trying the DI manifold. I think ill end up running both, tunning them and seeing which one gives me better results on my ets at the track. thanks for the input.
