Hey guys, I have a 199 L and I am wondering what kind of number I can expect when i hit the dyno this weekend. I do not want ot show up with unrealistic goals in mind. Here is a list of my mods, let me know what yo think..

1999 L
4# Lower Pulley
Stiegemeier Stage 5 Ported Blower
Ported TB and Plenum
Diablosport Pulley w/ 90mm Maf and 93 octane Tune
90 mm Maf
Razor Edge Carbon Fiber Intake Tube
Custom Airaid air box with K&N cone filter
Borla cat-back Exhaust


I know I need to open up the exhaust side of things to really see the benefits of the intake mods, it is currently in the works, any suggestions on headers?

Thank-you guys..

 

I'd bout 390hp 470tq

I made 470hp 580tq with stock exhaust(i was built with 16lbs from an eaton, stock fuel system also)

for HP gains you need to get Long Tube headers, I have kooks, dynatech are good also!!

good luck and let us know how you did!!!

 

I don`t know, My 2000 made 404hp and 515tq with a 4lb pulley but I had a Sal tune. Whose your tuner?

 

On my old 04 , It had 428 rear hp with a ported eaton, c&l upper plenum, cold air intake, single blade throttle body and a 2# upper pully.Preditor dyno tune. 93 octaine. sea level at about 65 degrees.

 

My '01 made 403 RWHP/518 RWTQ at 14.25 psi. Besides the pulley, the only other mods were a CAI, Bassani hi-flow mid pipes, MAC catback, and custom dyno tune by Johhny Lightning (Predator).

You can expect similar results.... maybe a little better.

 

I have similar mods, differences being I don't have a ported blower, but I have full longtubes on my exhaust, and my CAI is actually maxed, robbing me of some power. (old BABolt powertube)

I pulled 392rwhp/489rwtq. (our '99 and '00s have smaller engine intake flows then the 01+)
