Boss Intake Blower Dyno Test

[Towelly]

MOTEC is where its at for the new 5.0's. They have built in control for VVT, just as fast and reliable as Fords setup. Only problem is cost.... IIRC, all the Ford Racing "Factory" cars, like the boy racer and man racer or whatever they call them now, come with MOTEC installed.

Hit the dyno. With 10 to 1 motor. 17-18 degrees of timing and a very calm 11.0 a/f. The car peaked at 13psi at 7200 where we let off. Peak power was at 6600. Boost at 6600 was 11 psi. 585 rwhp and 486 ft/lbs.

With the motor still fresh. Going to keep everything mild and the dyno with the Boss intake will be with the exact same tune. We'll then see if anything needs to be changed. This motor is pretty good at keeping itself where you command though.

The first run was 10 minutes off the street, and the 2nd run was just a few minutes after that. No real cool down time. Both runs were within 3 rwhp and 4 ft/lbs. Very impressed at the consistency. The boss runs will be hot off the street as well.

Alright,

With the boss intake we made 612 hp and 501 ft /lbs of torque.

That was a peak pick up of 27 rwhp and 15 ft/lbs.

Pretty happy with that. That was with the exact same timing as the before run. Very Very conservative.

We lost down low, but the power carried out better. I'll have graphs scanned tomorrw. Peak power also moved from about 6600 to about 7050.

Decided to throw a little more timing at the car. We saw about 20 degrees and power jumped to 645 rwhp, and 518 ft/lbs. Peak power moved to about 7200.

We added 4 degrees (most i could add through the xcal) and put the car at 22 to about 7200 and then 21 to about 7500. Figured we'd lean a little bit on the car, I think it's still plenty safe at an 11.0 a/f ratio. FYI, all runs stayed exactly at 11.0 a/f! Car does what you tell it to! Very nice!
Peak power moved again, up to about 7350 rpms.

We were rewarded with a very nice 698 rwhp! and 542 ft/lbs. Not too shabby through an automatic car!



I'll have lots of graphs to scan in tomorrow. I have the rpm breakdown numerical graphs, that way you'll be able to see low end loss numbers as well.

Up for this weekend, R&R the fresh engine for some JPC heads and cams, no numbers til the 5.0 article comes out though.

Did u happen to make a pull with the old tune? Looks like there is a lot to gain with a tune! Congrats beef!

That's pretty damn impressive.. I'm going to have to ride in one to make up my mind on a PD blower or a centri.

Boss before and after graph with same timing, same boost, same a/f

Below 4100 tq is down, and below 4800 hp is down.

Peak hp pickup of 27, at 7200 the car is up about 50 rwhp though.

Peak tq pickup of 15, at 7200 the car is up about 30 ft/lbs

Good numbers beef. Can't be dissapointed about those. So when are the heads going on?

I'd be willing to bet that you're seeing some valve float with the RPM and boost on the backside of the valve. Do the springs in the new heads come with higher seat pressure?

I believe they are shimmed
