I will be getting my '96 LS tuned on the dyno next week with the following setup:

Comptech intake w/ Ice Box
DC Sports 4-2-1 header
Thermal R&D exhaust
STR cam gears
APEXi S-AFC

What kind of whp numbers am I going to be looking at AFTER it has been tuned on the dyno and everything? Any input is greatly appreciated. (I would like to have a general idea so there is no negative surprises next week).

 

Like a max of 150 whp... If you make that much I'll be surprised, but there aren't too many hp adding mods... Basically you have just made the car breathe better... Just my .02...

 

woops, I forgot to mention cams as well

 

Well a stock LS will dyno at 105 to 115 whp on the average from what I've seen,with your mods you should be around 135 to 140 whp.

 

What kind of cams?

 

Cams can make a big difference...

 

exactly!!! with the proper tuning, big gains can be made..

BTW what kind of cams?

 

cam gears?

 

I would also say 140-150..maybe slightly more depending on what kind of cams they are.

Did you do a baseline run yet? I usually see LS's dyno at around 118 stock.

 

Stock LS dynos low to mid 120's

Depends on the dyno used and the ambient conditions. Each car differs too.

140 stock - (140x0.15) = 119.
15% drivetrain loss (FWD).
This would be typical.

 

Yeah, but its not a straight cut 15% loss....some lose more than others through the drivetrain, and some motors are stronger from the factory. On average around 120 is about right.
