Had the Z on the dyno today and was fairly impressed with the outcome. Put down 278 HP and 380 Trq. On a 50 shot was at 315 and just under 425 for torque. Does this sound about right for the car. 140,xxx miles,longtubes,hooker y-pipe,TB, programmer, AFPR, SS hood and ram air intake?

 

Nice torque! I have no idea on the #'s though .. I would have thought them to be a little higher, what dyno was this on?

 

Dyno jet at RaceRelated. I was impressed with the torque but was kinda hoping the Hp was going to be a little higher

 

only 278 without NOS? I thought it had about 285 stock?!!

 

LT1 is only 275 stock to the crank. So do the math. 141.xxx mile and basic bolt-ons. Im happy. Look at the torwue though

 

What was the A/F ratio.
Is the car running really rich.
There is like a 100 more lb ft of torque over HP.
That just doesnt look right.
Is the car a automatic?

 

Air/fuel was at 12.41, so a little lean. Car went only a little lean when i sprayed. So for now ive added a bigger fuel jet and changed plugs. The car is a 6-speed

 

this is a dry nos kit right? if so, those numbers were right on par, esp if you dont have a bottle heater to get the pressure up to 1100 psi

 

This is a NOS wet kit. No bottle warmer. I sat in the back of the car with a heat gun getting pressure while James at RR made my pulls

 

1) thats ghetto and not really that smart
2) i am sure your bottle pressure wasnt that high. wet likes 1200 psi.
