Ouch, those NA numbers are LOW!! Even your N20 numbers are low. Most cars spraying a 150 shot usually see around 430-450 at the wheels.

then all my cars must suck bad then. the 99TA i had just last month dyno'ed 278 all stock. both were completely stock. right down to the paper air filter and exhaust tips. the 00 formy has 49k on it. the 99 TA had 94K on it.

oh and if you want some higher numbers, here's the same dyno just in STD instead of SAE. jumps up 10hp/10tq.

and to make things better here's the wife's car dyno today vs about one month ago. down 14hp/19tq. there has been no changes made to her car. to explain it. correction factoring sucks in states where humidity is high and alitude is low. still not accurate.

I'd say it's conservative... my 99 SS STOCK to paper filter was 306/316. (A4)

Your AF looks very fat on both runs. 12.0 or lower NA and not even on the graph on spray.There some of your missing HP right there.

mrr23

iTrader: (3)

well that's a factory tune. nothing has been done ECM wise. and i thought 11.8 is where you want to be coming out of the tailpipe anyway?

2000Blackout

iTrader: (1)

11.8 NA is way rich,Na i would say 13.0 is safe enough.Get it tuned,you should see a nice gain.

Cats will affect your AFR if you're using a tailpipe sniffer - preferably put the wideband in an O2 bung during the dyno. That might be difficult with stock exhaust manifolds, though I believe 11.8 is the stock AFR, most of us lean it out to about 12.9-13.1 on the road (~12.6 on a dynojet) for NA cars.

well the wife's car was 13.0 out the tailpipe with cats. and no tune. but, she has mods done to hers. VHP airlid w/polyfoam filter, VHP MAF ends, bassani headers w/y-pipe and hi-flow cats, borla catback,VHP 1.89 accelerated lift rockers and dual springs. so, in theory all i need to do is install all those things and i'll have the same 13.0 with no tune.

IIRC increasing the induction & exhaust flow does lean the car out. The MAF ends can do it too depending upon how they're calibrated.

yea, your a/f is costing you quite a few ponies, get that leaned out to 13.1 or so, mine is at 13.3 now.

the MAF ends brought my o2s on the wife's car from 990-1002 to 890-910. i'm going back friday and leaning out the fuel on the n2o and see what happens. i put the SLP airlid on today. so i'll get another NA run also to chart the difference.

The N20 pull A/F is WAAAAYYYYY off. After 4k it is below 10/1.. How much pressure did you have in the bottle?

mrr23

iTrader: (3)

1000 psi per compucar. the pill listing for 150 is 63/35 i only have 33 or 37. so, i went with the richer pill for insurance. i'll try the 33 to see what happens.

I run a compucar single nozzel system my self , where is your nozzel placement.have you taken it to the track yet, curious on some track #s. On a 90shot in my car with sometraction issues i gained 8mph and 8 tenths, for what its worth. This kit on my car is for a mustang (HEHEHE) but it does work well for the money , I have no complaints.
