Ha ha ha, well I'm going for Dyno tuning somewhere else in a month or so, I will know the differance then.

 

bump for more dynos.

 

I wish you had dyno'd in 3rd

We would have gotten some sort of comparison between my two dynos and yours. Mine sans piggy. The last time I went to the dyno they didn't do a 4th gear pull cause they said it was too long a gear to pull in.

Oh well

And yes I had them do it for 2700 pounds. Did they do an initial pull to measure parasitic loss?

WADAD

 

It was a 3rd gear pull, unfortunatly they didnt do an initial pull to measure the loss.
I wish i knew the differance the weight was.

Also, they said today that they used the mustang dyno but calibrated it to Dyno Jet numbers. Not sure if thats true or not, nor if its possible. Im really confussed now, my numbers dont really mean anything to me.

 

Should have gone on a dyno jet and maybe with a wideband.

 

what will a wideband do for me? (sorry dyno newb here)

 

Won't do much, it will just show you where exactly you'd have to take out or add fuel to get maximum horespower. And it will show you where you are lean or rich. More info about your car's performance for maybe $15 more. Take a look at my dyno in this thread, on the top of RPM i was too lean and probably lost about 5whp.

 

dyno numbers only have meaning in two cases, as I see it. 1st- the same car, same dyno, new mod and the dyno measures the change from before. 2nd- to tune for max power based on that dyno but you won't get the same number on another rolling dyno or on an accelerometer based (GtechPro) or computational (Auterra) dyno. Dyno numbers are essentially meaningless when compareing to another vehicle or dyno.

Wideband is useful if you have a way to tune the fuel or timing. You tune for the ideal AFR for your vehicle. For us it's about 12.7 (NA) I don't know what the ideal is for FI; too much leaner and you risk melting stuff if you run your engine at high RPM for a prolonged period (i.e. track day).

 

Thanks for the info.

 

is there a way you can you use an equation to correct that now that you know what the TQ is and the weight?

 

I would have already come up with one if there wasnt too many unknown variables.

 

Hi I am new here so I think your gona be interest how many hp I took to my

Mirage LS with 4g94 engine block 176hp with 158 torque.

 

awesome. lets see the dyno sheet.

 

Screw that- let's see the modification list. 176 from a G94 smells like a nicely tuned stage 1 turbo.

 

I wish it could be N/A but I know that's impossible.
