So there was a local toy drive at one of the performance shops in my area so I decided the take my trans am there.

The car is a 1998 M6 Trans am with about 120k miles on the clock STOCK TUNE!

DYNO IS ALL MOTOR, NO SPRAY.

My mods are:

Pacesetter Long tubes
Off road Y-pipe
3" electric cutout
LS6 Intake
Aftermarket lid (unknown brand)
Smooth bellow
Free ram air mod
De screened MAF
Throttle body by-pass

Car has 275/35/18 tires with c6 z06 rims. (dont know how much the extra weight from the wheels hurt if any)

365.7 RWHP

373.2 RWTQ

The dyno was a Dynojet

Let me know what you guys think. Also I'm confused as to why it has engine speed (MPH) on the graph instead of engine rpm?

Very nice car! What dyno was that on?

Very nice car, but that's one happy *** dyno.

The graph can be set up for RPM or MPH, if I remember correctly they use MPH if they're having issues with the tach signal pickup to get RPM.

It was a dynojet, not really sure which model.

That's a great number on the stock tune

Pretty sure the correction factor was a bit high, that is what full full bolt on LS1 cars usually dyno. But dyno #'s should really be taken that serious, they vary from dyno to dyno. Track results is what should be taken more serious.

I agree about the dyno being very giving. I hear dynojets are the higher reading dynos.

And thanks I didn't know that about the rpm signal. I do wish I could see what the car was making at different rpm's.

Oh well, guess ill wait till I get my cam to go with my ported 243's.

Yeah, id say 370 rwhp is a bit generous. More likely around 350 rwhp with those mods.

Wow that's crazy. I need to try a dyno jet.

STD would be more like 353/360 which for the mods given is impressive but
not outrageous.

raytx1

iTrader: (1)

Do you mean SAE? Because this was dyno'ed on STD.

thunderstruck507

iTrader: (18)

With no tune I wouldn't even buy that.

raytx1

iTrader: (1)

Yeah I knew dynojets read high.

Anyways, what do you guys think of the power curve? Is it lacking power anywhere is shouldn't be? I'm not too familiar with dyno graphs.

HPP explains it. Their's never seems to read what other area dynojets will read.

The curve looks great. Time for H/C/tune!

Any track times to back up the dyno?

iTrader: (6)

I dyno'ed 360/390 fwiw n/a

A.R. Shale Targa

iTrader: (2)

Correct....I was thinking/meaning SAE and still typed STD....I'm such an idiot

Good numbers, seems about right to me. Even though I belive Dynojet Dyno arent as accurate. My tuner/builder has one and he doesnt base his self alot of what the Dyno says.

Yeah, the numbers are high, but it's always best to leave the dyno with unusually high numbers rather than unusually low numbers, IMO.
