FRPP intake/TB dyno test on 09 Bullitt

We just did a dyno comparison on the FRPP intake and TB compared to stock on our 09 D1 Procharged Bullitt, and thought some people would be interested.
The car has a D1SC making about 11#'s of boost, FRPP Hot rod cams, SS Works Long tubes and stock cat back exhaust on the before dyno run. For the after Dyno run we added the FRPP TB and intake, and only adjusted the tune to keep the AFR's good. The SAE correction was .99 for the before and 1.0 for the after. So everything was almost identical for the two runs. It was 96* in the shop for both pulls.
Here is a dyno vid, a few pics of the intakes, and the dyno sheet.

We did a Kooks Header and FRPP intake/TB swap on another Procharged GT last week and the car picked up 60 hp, so we wanted to isolate the intake/TB combo to see how much power it made by itself, and we were pretty happy with the results.

Nice. Very nice gain. Thanks for the numbers guys.

I know this will be asked, was the "before" with delete plates or not?

And nice gains either way.

I would assume delete plates were already installed if they already had a d1sc. Could be wrong, of course.

No, the before did not have delete plates. The intake was completely stock.

Well fuck. I guess the gains we are looking for aren't gonna be there with this intake. How much of the gain could be due to the delete plates?

So you don't think those are good gains? I did back to back testing on the CMDPs back in early 2008 and they only gained 6 rwhp.

38rwhp and 14rwtq isn't all that bad. Pretty good gains.

did the boost decrease?

Ya. That doesn't make much sense.

what doesnt make sense?

id like to know if the boost pressure decreased too!!!

i have a procharger, and right now this thing is looking quite nice!!!

Larger throttle body and less restrictive intake should mean less restrictrion correct? Manifold pressure is a measure of restriction.

The graph shows the boost curve at the bottom. I see no drop at all, and an actual increase through a good part of it.

Boost is a measure of manifold restriction....thus reducing that restriction should result in a reduction of boost pressure.

hmmmm...interesting. youre 100% correct. i didnt notice that. good catch!

I noticed the slight increase as well. .3psi is negligible.

Which is exactly why I said it was strange.........

word

Boost remained pretty consistent after the long tubes and then after the intake as well.
