Hood open will only really allow for heat to dissipate better.
With a SRI system you are limited in air flow already with the placement, open the hood would create the wrong air flow (i.e. more than what would be in a real world environment).

CAI system, bumper off might be closer to real world, but I have not done any work with those systems...yet.

Aside from heat dissipation, that might not necessarily be true. There are intake ducts in place for the stock air boxes that will help pump air into the engine bay.

I'm doing 4 runs, two before and two after. I will commit to doing it all on the same day if the shops can work it out. The shop with the dyno and the one doing the install are not the same. So I want the atmospheric conditions to be the nearly the same to show the gains if any.

So how about after they are installed I do one run with the hood open and the other with it closed?

When are you supposed to get the FI exhaust?

mid-September it looks like.

They look awesome, spendy though. You planning on doing another run when you get them? I'd like to wait and see what you get.

I will be back on the dyno for sure. :tup:

Thats Funny! LOL

did you hear about the Takeda intakes??

apparently its short for take da shit out
