My DYNO run RESULTS!!!!

[The ANTI-RICE]

96 GSR
JRSC@6psi
GReddy P.E.
GReddy Header
AEM w/RACTIVE HEAT SHIELD FILTER
WAAAAY RETARDED TIMING!! (For SAFETY!)
17" Wheels
Stock JR Fuel Psi Reg. setting
B&M FPR@ 55
55,000 miles on car, 10,000 on blower-miles

All in all, a VERY good HP turn out for no TUNING since install!

I think my TACHOMETER is off a little bit, my redline is at 8200rpm's, however, i shut the car DOWN at 8000rpms, but as you can see the the DYNO shows shows about 7800 or soo, o well.

Do you think if i had KEPT GOING, it woulda made some more power, or jus NOISE?!

Please help me diagnose what all is goin on in my GRAPHS.

Thanks,
Tony

Damn. That's fantastic. I only came up with 199hp with my 6psi GSR.

[Holden]

There are three methods of correcting for weather conditions. DIN, Standard and SAE.

I hate to break this to you, but that graph is using DIN correction factors, which result in the highest HP numbers.

Standard correction factors are next in line. Most aftermarket manufacturers use "Standard" because they can claim higher HP gains. Standard correction results in lower HP numbers than DIN.

Finally, SAE correction factors are the ones used in almost all the serious discussions that go on (including this board and most DynoJet graphs). SAE correction results in the lowest HP numbers.

It looks like that shop is aiming for happy customers (not that they did anything wrong). I would ask them to convert your graphs to SAE and print them out again.

I'll try to dig up a way to convert from DIN to SAE and post back.

I remember him asking me what i wanted in NUMBER WISE dyno... I told him, "Uhh, duhh, i dunno, what does most everyone use?"

I guess he wants to make people happy.....o well.....HE SUCCEDED!!!!

Well, I can't find the formula for DIN, but here's what I have:

SAE correction corrects to atmospheric pressure of 29.23 in/hg, 77 degrees F and zero humidity.

Standard correction corrects to atmospheric pressure of 29.23 in/hg, 68 degrees F and zero humidity.

I don't have the DIN formula, but here is a comparison:

Same run converted by all three factors:

SAE ======= 412hp
Standard == 423hp
DIN ======= 425hp

This next part is probably inacurate, but if we take 412/425 = 0.97 as a factor, your best run of 210.3hp converts to 204hp.

Hey! 204hp is not to shabby! I thought there would be more of a difference.

Way to go! I bet that sucker will tune up to get at least 210hp (SAE).

Hey, your the one wantin to open up a DYNO SHOP of your own! I would expect nothing less from THE MAN!

Pretty cool though....Does the HIGHER the HP, mean MORE of a correction factor?

Say i dynoed at 270 DIN, what would THAT convert to?

Thanks

dyno is just a number until u start fine tuning everything. plus for force induction, if your power peaks at redline, you will most likely be on a bit of the lean side. when the motor is on the rich side(FI), most likely power peaks earlier from redline, but when you peak at redline or close, its usually a sign on running a bit on the lean side. just a friendly reminder
