What should i Dyno? I have a 95 Z28 with 52,000 miles on it. I have Mac Headers, Off Road pipe, Mac cat-back, LPE cold air intake, and a 160 thermostate. 6 speed.

What numbers shoould i get? i'm hoping for 300rwhp

 

i'll say 290rwhp

 

275

 

I think you'll be right around 300 or so.

 

my setup did 225 hp. of course that was on 7 cylinders and running real rich. i got accell 9000 header wires and it went to 289. both times the A/F was at the bottom of the rich scale. the consensus seems to be that the egr is stuck open, hence the egr code. i got SJM block off plates and havent installed them yet but should put me over 300. The point is that it all depends on how well the car is running. theres really no way to tell with out getting on the dyno. you might find some problems that you hadnt noticed before. good luck.

 

I say anywhere from 270 to 285.

 

My dyno numbers below with AS&Ms, RT cat, borla, CAI

 

id say 280-290 is a safe bet....long tube cars usually are in the 290's

 

Don't worry about what you should be dynoing until you dyno. Some of the numbers you may see on the board are a little odd. "Doctored" some may say.

 

People some times forget to mention STD or SAE...so which ever is higher...that is what people use.

 

My car dynoed at 292 rwhp and 330 ft-lb with a similar setup.

 

400 horsepower

 

I would guess around 285. I dont think your gonna get to that 300rwp mark but you'll be close.. Keep modding!
