Boss Intake install and dyno

[Wharf Rat]

Got my intake yesterday and installed it. Took me 2 hours following the great instructions from LRS.

This thing is huge. Looks like a composite tunnel ram for an old FE or something. Check out the valley! Engine burritos hell... could cook a 15 pound turkey in there! The pics don't do it justice.





I went with a BBR tune. I have gotten 3 tunes from teim and the AFR's have all been spot on.

Here is the graph. The car has a BBR tune, JLT CAI, Magnaflow O/R X-pipe, Magnaflow catback, and the BOSS intake. Run 9 is same setup with stock intake.



It cuts off a little early but looks exactly like everyone else's Boss intake dynos. Loss of 10-20 hp and tq from 3500-5500, dead even from 5500-6500, and huge gains from 6500-7500. If you extrapolate where those lines are going the gains at 7500 are 40+ rwhp. Don't let the loss of midrange scare you. I couldn't notice it but I sure as hell can feel something is up that last thousand RPM before my Raptor lights up (7,500)!

hell ya man, you had some good runs at firebird the other night, what was your best pass

Had a 12.39 and few 12.4's at Firebird last night but today I clicked off a 12.17 and a pair of 12.3's at Speedworld.

Did you get any vids?

Car is flying, congrats!

I want one :)

[Wharf Rat]

Thanks, still about 2 tenths slower than what I wanted, though. I think I'll need better than 2,500 ft DA's to hits 11's as it sits. If you get one get an auto. The auto 5.0's are FLYING!

Actually I do have in-car vids. I'll try to post 'em up this week.

WharfRat, I also have a '11 GT. I put the Boss Manifold on last night and got it dyno'd today. I also have a tune from BBR.

Did you make any dyno pulls above 7000? On my pulls the tune went pretty rich around 7200 - 7300 and the power dropped noticeably. Posted on the LRS forums asking if this was normal.

Your power and torque level off well before the rich spot.
I would rather have it go rich up high. What do you usually shift at?
