Son of F-P?

If someone wants to send me a C&L or a fab. one I will test and return.

 

No its Grimace, lol. Now i want some Mcdonalds cookies dangit...............

I just got home, been drinking at beedubs (Buffalo Wild Wings) got another beer and spit half of it on the cp screen. That was some funny shiza. And yes, the fur raised IAT2 temps, but the iced intercooler kept it down a little.

 

No flame but be careful how you do this testing. I have little doubt that your F-P has helped with flow but 7 psi to 2 psi seems like too much. You didn't modify the air filter in any way at the same time, I assume.

Vacuum measurements can increase if they are taken at a high flow area. The velocity at the opening creates a localized pressure drop. Your F-P is larger in cross section and thus it'll have lower velocities at most points. Try to be sure you take all vacuum readings at some point with the lowest possible flow. This will best represent the actual vacuum.

 

Both reading were at the same spot, guage, and hose. If you look at the pic. you can see the hose. I just pulled it out of the stocker, and put it right back in F-P.

Long before F-P I did the stock airbox 2 hose thing and a K&N. Nothing changed but the upper.

 

Honestly, the test needs to be done on a dyno, with the same truck, on the same day. Any other test has too many inconsistancies and variables.

The vacuum test is interesting, but I also think it's not a fair test of performance increase. If you put a larger area before the inlet of your blower, you ARE going to drop in vacuum because you are drawing the same amount of air in, but through a larger space. You are not increasing the air taken in, because the size of the blower inlet has not changed. So I believe your vacuum readings to be correct, but I don't feel they related to anything else.

Again, you'd need to dyno test it to see if it actually raised the hp.

 

I posted this on the H-D forum some time ago
"I took off .5 sec with that "thing" and a 2lbs upper. My best was 14.1X, at 2 different tracks, on different days. Now its 13.6, with no traction."

If you want I can ship it to you to test.

I did open up the blower side a little, I used a gasket for sizing. The TB side didn't need opening. Even if I opened up the blower side to a KB size, the TB side would still limit the air flow. No matter what was done, how it was made, ect.



I just didn't want to spend $200-600 and get the same thing. It was also fun to do, nobody can see if it I don't open my hood.
