Default FM13 with full exhaust

I'm wondering how the F13 will respond to a car with LT's, Catted Y, and a catback. Almost all the numbers I see are on cars with duals. While they make impressive #'s w/ duals, the lower lift on the exhaust side of the cam sorta worries me w/ a full exhaust setup.

So does anyone have a cat/Ypipe setup w/ the cam that can post numbers, or a graph would be best.

Or if you have a graph of the F13 on a 112 or 114 just post up, i'd like to see how the different LSA affects the curves as well. I know the 112 will peak alil higher ...

I think your car would pick up a bit going to the F13, probably about 10 on both hp and tq.

I tuned a car that made 393 rwhp on 115,000 mile bottom end. It was through FLPs (1 3/4) and Borla.

I put down 391RWHP (F13/114LSA) w/SLP longtubes into random tech cats and through an SLP 3" y-pipe. Dynoed in about 95+ degree weather in Arizona.

99BackNBlackZ28 - Nice #'s ... i guess i was worrying for nothing. Thanks guys

Mine will probably be thru RT cats as well, and a custom 3" pipe that should flow very well. So I guess I shouldn't have any problems maintaing my current power levels.

Tech was that car an auto or manual? Stock heads? I have similar miles on my engine and keep vacillating about putting this cam in because of the high mileage.

Is that a 112+2 or +4? Nice numbers btw, if i can hit right at or just a hair under 400 w/ torque like that I'd be very pleased.

A 112 LSA is for M6 cars and the 114 LSA is for automaitic cars.

See sig. And this was with a mail-order tune, in 95 degree, humid *** Florida weather. I got the 114 LSA because mine is a DD and I wanted as good as possible streetability. I'm sure with a full tune I could get closer to 400 rwhp.

Do you have a copy of the dyno graph by any chance? I think I've decided on the 112+4, but would like to see how the 114 in a M6 looks.

the 400/390 with with a 112+4 but i was thinking if i ever had it apart i might retard it two degrees just to get the peak a lil higher in the rpm band

i dont think i would want anyother cam but this cam
its perfect for what im doing
great power, drives like stock with a good tune, and with a set of good heads and a 90/90 you lookin at 450 to the wheels maybe more

The way the 112 will handle itself in an A4 is in the tune.
But the 114 will have more vacuum which is a plus with A4s and brakes.
