Something doesn't smell quite right with this dyno's #s? They are way too far off. I have never seen a dyno put out more than 12% different than any other kind. I'd definately like to see what #s you'd put down on a dynojet or mustang dyno. 533 is definately do-able @ 23psi.
Also, I've seen logs of 100% duty cycles on 1680/850cc injectors @ 40psi base with a bosche pump rated for 90psi, @ 8000 rpm 21psi on a race-port/GT40R. Even at your leaner a/f and your 10 psi higher base pressure, that still would not bring his duty cycle below 85%.
I'm not hating, just confused by the #s.

j/k eric
It's funny how all these # game works. If I said I was only making 200rwhp and trap 100mph in the 1/4. people would say BS. either the track was wrong or I'm making more hp than I claimed.
but when it comes down to dyno #'s, people are just the opposite.
go figure?

I told you, all I wanted was to run 10.90's @ 100 mph

I told you guys, this Dyno can't get any business because the numbers read so low...... It's a great tuning tool but it's def not for bragging rights.

I was editing my post when you replied. 533 is definately possible with your set-up at 23psi.
as for the 2nd part, ME TOO!

Eh, I need some better fuel anyway, stock lines and fat injectors arent cutting it.
Why post dyno numbers anymore if not dyno'g at a credible location, who can blame those that don't buy it.
If you are gonna step in it anyway, why not make sure the sheet looks credible, then post up a clear scan of the sheet, then let folks either get green with envy or blast away with BS flags. With no sheet and a debatealbe number your post gets what it deserves.
I bet it's a thrill ride, that's what counts anyway. Go tear up the 1/4 mile and let us know how it does.

It was fun watching your car though, Eric. Man, that's a monster of a car. And Ron, of Davinci's motor works, thanks man for preparing my car before the tuning day. That was a great deal you gave me. You guys in that area are so fortunate to have a shop like Davinci that knows your cars. Same is true with Axis Tuning, great price - great service. I wish we have the same kind of shops here in the Memphis area.
We had a safe trip back. Now that I know its also safe to floor the gas pedal. I hope to be content with the power in the car now, at least for a long while.
Best regards.

Next time, we'll go clubbing instead. remind me never to park in that spot again.
its not used for bragging rights, but you're multiplying everything it puts out by 1.20 and THEN bragging about it?

so if i go dyno 300whp and the tuner tells me it reads a little low, i can come in here and make a thread with the numbers it *should* have been? like I DYNO'D 360whp?!!! craziness

Well done Lupe whatever the figures, it's alot better than it was before Steve tuned it. Carl you keep mentioning a dynapack a dynapack reads power at the hubs not the wheels. The dynodynamics is different from a dynapack. Dynodynamics is what we use here in the UK. Power reading is very accurate, I believe rice racing would confirm they have a good rep in Australia too.
if there is a 15% difference to a dynojet then the 470rwhp I got at 1.2 bar on a dynodynamics equates to 540rwhp on a dynojet which does sound a bit much.
Nevertheless good job done by all. I will be back on the dyno within two weeks, we have a very similar setup so will compare then.

I'm sure this is the reason why there's a lot of negativity on their "accomplishments".
I really don't care how much power they made.
Congrads to them...
But to tell everyone that engine break-in's are not necessary - isn't that a bit too much???

Actually, I feel that engine break in on a rotary isn't necessary either. Unless its brand new and that hasn't happened in 10yrs. IMO, as well as my tuner say a few heat cycles, change your oil and have at it!

Lupe ditch that A 1000 pump and get the Aeromotive Eliminator. It looks identical but you will be amazed at how much more fuel it pumps compared to the little brother. You will be able to run a least a couple more psi and have lower duty. Good job!!

I have seen engines go directly from the stand to a 9000 rpm dyno run on a dynapack with no ill effects, if its clearanced right and built right, there wont be a problem..Max
