I saw this on Streetfire.net. i dont know if its been posted. That supercharger looks good

Dang that charger sounds sweet!!!! That is a nice gain in tuning. nice to see.

 

I just got home from that place! There were 5 Cobalts (every color but blue) that met up there for a dyno day this afternoon (thanks for setting it up, SilverSS). Someone asked about tuning and they told us the name of some other place to go to, that's f'd up. It was too hot today, anyways. Everyone dyno'd much lower than we expected, a couple of stage 2's getting around 210 hp / 200 tq range. Someone also tripped over the wires for the A/F and ripped them from the computer, no A/F readings for us after that...

 

I want to know what that first song is, sounds sick

 

oh so its in Florida?

 

Yep, Clearwater FL.

Edit: Oh yeah, that dog in the video (Zeus?) needs a bath, my white shorts are grey now...

 

That was a pretty cool video. I never exactly knew how a dyno was done. I knew what information it provided, but....

 

I was under the impression that a stage 2 would give around the 245 whp mark. Am I mistaken or did these cars run extremely low numbers?

 

It depends on the type of dyno you use. A dynojet will typically show much higher numbers than a mustang dyno, I'm no expert on why but that seems to be universally the case.

 

I'm assuming this was a Mustang dyno? I have heard read why, I just dont remember. I thin it has something to do with one uses pulses of force to measure and one is a constant measure. But I could be completely off.

 

^^^^ I believe it has something to do with the correction factors ......?

 

lol, i just posted about this like 2 weeks ago. they use the same correction. it depends if its a load bearing or intertia type dyno, they have md's that are inertia like a 248c from the dynojet that will show similar numbers... but most are not. gm uses mustang dyno's for there numbers and md's are much more accurate to real world as load is actually being applied just as it would driving down the road.

 

thats linefire, hes from redline forums. i put down a horrible 232hp with just STG2 tune and 2.85 with no HP tuners. I was pissed because i have seen 242 with just an intake and 3" pulley. some say i have a factory freak

105 degress and humid ass florida in a hot garage doesnt help either
