Going to Dyno for the 1st Time!

[shanetastic]

I am going to the dyno next weekend. I have spent quite a few dollars on bolt on's and I am a bit nervous about what the results might be. Does anybody know about what I should put down with my current mods?

Thanks!

245-250 rw

 

[CottonBurnerz]

I say 260-270 rwhp

 

[Slapyo]

my guess is 250-255. gotta post up the results as soon as you get them.

 

[03Sleeper]

270rwhp

 

[JonJon]

270rwhp

03Sleeper, did you get dyno'd yet?

shanetastic, I guess 260rwhp. You have almost the same mods as me (I'm ordering 75mm tb) so I'm definately curious what you pull

250-255

270 seems a little high to me. im guessing 250 or so. (plus or minus 5 hp.)

I say don't buy bolt-ons. Put the money toward a blower. I am learning this the hard way.

Thanks for the info. I'll post the results as soon as I can! I am hoping to reach the 260 mark!

Dyno Results are in...

I am a bit dissapointed at the results, but hey, the car does have 100,000 miles on it. The graph was off by 100 on the printout for some reason, but the max power and max torque numbers are correct. I noticed that the Air/Fuel is quite lean....

 

[CottonBurnerz]

I'm surprised that it didn't hit 250 mark.. that's a lot of dough you put into the car. Any more plans for it?

 

[Turbo92PGT]

It kinda pisses me off that all the mods we put on our cars, dont hardly do jack 'Kiss Me''Kiss Me''Kiss Me''Kiss Me' but take our money. Its kind of a bunch of crap. You dont have as much trouble as the 96-98 guys either.

 

[zgarske1038]

numbers look right to me

 

[JonJon]

when did you get that diablo chip

 

[CottonBurnerz]

The o/r X pipe + magna cat-back should set you around 240-250 range already. Then you have tb/plenum + pullies which should put you up around 245-255 range.. maybe it's the chip?

JonJon u need drag radials man forget the t/b I wanna see ya gettin some traction up at capitol when i finally bring my beast out man! Oh and i was way off on the guess i guessed like 280 w/ the diablochip and if ur car was running lean then how come u didnt have them tune it to get a lil more fuel? Maybe it wouldve given u some more power

 

[Roush21]

Oh also w/ 100,000 miles your definetly going to have a few hp less than a motor w/ 1/2 that many miles on it...Next mod for you should be forged motor!!!!!

I have never been to the dyno and didn't know how lean it was running. I asked the people who were operating the dyno about it and they said that running the air/fuel richer would probably increase torque but probably decrease horsepower. Running lean creates more heat and is not as safe as a richer mixture. Torque requires more fuel. Leaner is "meaner" in relation to horsepower. BUT...I wonder if you get too lean if HP actually decreases?

I noticed that smoothing on the plot was set for 5... that can make the peak numbers more honest, but with smoothing off and a jagged plot, you could easily have a peak reading that's 3-5hp higher.
