If I can wake up in time I'll get the dyno done and when you see what the results are you will all feel like asses for believing the stage kits are weak

Evilfrog

True story.

Matty

I hope you are right.

plyboy-illest

put the same size pully that the stage 2 comes with and then it will almost be the same # that everyone else would get ... becaus eim sure your have your smaller one on

Anybody monitor the timming when doing the dyno runs? Would like to see how much timming they took out with the reflash. There are a ton of boost limiters built into the ECM that could cause timming to be taken out.

Okay I am ready to post the dyno but background first.
The pull is much better but the numbers don't indicate that actually just the opposite.
Second it was done at the same dyno, same technician BUT this time NO RPM hookup he just based this on wheel speed. I do not know if this makes a difference. Anyone who knows say so quickly for everones sake.
The graph has my previous numbers with the new ones. I am seriously wanting to go else where but this was where I had the previous dyno done. I am very pissed that the tech never told me about the difference in the test from last time(not done on RPM's)

Also when these horrible results came out the A\F ratio was good and I was making almost 5lbs more boost. The tech said it didn't make sense to him. Can we all just hope he's an idiot and did something wrong????????

nick11

we appreciate you giving us this info on the stage 2 soo quicky... I would be happy to have a cobalt pushing 250 whp .... but you have soo many mods

Matty

What I want to know is how does it feel? Good? Ok? Awesome? So-so? The street tells alot.

Never heard of a tech judging when to end the dyno based on "wheelspeed". Sounds like a moron to me.

It feels good not awesome. When it gets to about 3500-4000rpm it pulls good. Thats why the numbers make no sense to me. I just want them to be wrong

He said the machine was basing it's test on the wheels speed because hir rpm hookup(sorry I didn't pay attention to the actual name) wasn't working.

please test soon so that we can say stage 2 good Kinetic Motorsport bad

Speed is hard to judge. I get used to my car all the time and start to wonder if it's getting slower. Then I race someone and realise that the car is every bit as fast as it was before.

Go race someone and tell us the results! (on the track of course )

My stage 2 feels AWESOME!! No way just a 16 hp gain. I am trying to set up a dyno date for middle of next week. Unfortunately, I don't have a base to go off b/c I didn't care before.

Thanks, I passed basic physics, how about you?

Horsepower/ A unit of power in the U.S. Customary System, equal to 745.7 watts or 33,000 foot-pounds per minute.

Torque/ The moment of a force; the measure of a force's tendency to produce torsion and rotation about an axis, equal to the vector product of the radius vector from the axis of rotation to the point of application of the force and the force vector.

Now which do you think you feel??

Take 2 cars geared exactly the same, same weight, etc. One has 300ft.lbs and 300 hp the other has 300ft.lbs. and 400hp, guess what??? They will FEEL the same when accelerating.

Same scenario 300hp for both and 300ft.lbs and 400 for the other. Guess what the one with 400ft.lbs will FEEL faster and depending on the gearing and weight they might still accelerate the same.

280Z1977

Has anyone CONFIRMED the 7000rpm redline???

TheToolmaker

I am still confused how you got your numbers. You say the guy went off of wheel speed. In that case, the car would not be making full power. My car is alot faster in every gear. I saw the Tech2 post the other day and the guy hit 36 mph in first, so if I am understanding this all correctly he stopped way short of redline on your dyno too.

PLEASE CORRECT ME IF I AM WRONG!

p7x

yes I was joking, Im guessing that either some time needs to pass or GM potentially screwed up the reflash or any number of things.

Asstyme

I thought you opened this thread by saying there was a loss of torque ? Also, don't the torque numbers seem low both before and after ?

TheToolmaker

Yes the 400 torque one would feel faster b/c of the fact it has 100 lb more torque. You did not read the equation though.... the one with more torque would have more hp if measured at the same rpm......

gracias senor, i missed that thread.

The chances of it being measured at the same RPM are slim to none. EITHER WAY! You do not feel horsepower, you feel torque.

This might uncloud your brain... http://vettenet.org/torquehp.html

that dyno looks messed up, our cars dont even allow the motor to go at 7800 rpm......
