Any dyno days going on soon !!
 

I really want to dyno my car but i want to see if theres a dyno day coming up soon . If not than someone should set one up .

please let me know if any is going on or going to happen.

Call GTR High Performance (909) 987-4352. They do three pulls for something like $65-$75.

With AFR? Wonder if they do a discount if we did a dyno day and brought in 40 +-.

Yes, with AFR. I'm sure they would give us a discount if we brought in a bunch of cars. Do you want me to call Gonzalo and find out how much they would charge?

Yes please. Maybe in the Fall when it's cooler.

I'd be interested in that.

I want in on this shit yo!

Found a spot I'm going to tommorow to get my car dyno it's 50 bucks for 4 baseline hp pulls and 1 torque pulls....

let me know if your interested I can tell the guy to open is shop up on Saturday if a few of us want to go .

Let me get a count who's in for the weekend (Saturday) ?

Uhm I dont get it, why wouldnt you get torque readings on all the pulls?

You know good question I think cause he has to use a different software but idk really ....
Maybe cause its a dyno Dynamic not a dynojet also can be the reason ?

That's sounds a bit weird because you cannot calculate HP without knowing Torque. HP is derived not measured. Torque is measured.

Exactly what I was going to say.

Wait ya that's true than idk why he said that lol but even his web site says 4 baseline pulls and 1 torque lol
So idk but you u guys down ?

Does his website also have links to you tube videos of cars jumping off dynos? Cuz if a dyno owner is saying a HP baseline run can't measure torque as well I am not entirely sure I would trust his shop.

Oh wait... I got it!!! Its a Honda tuner... they don't calculate ft-lbs of torque psssh come on guys... they only measure in HP after vtak yo

The only problem with that many cars is it is one long ass day for everyone. Even 20 cars is a long day, unless they are really squared away.

We did like 50 once without AFR and it WAS a long day. But there is was some dicking around.

:judge:

That's why it crosses at 5250 consistently.

Not consistently. Absolutely.

Well, not always. ;)

Always.

horsepower = rpm x torque / 5252

Or

a = bxc/d

a will ALWAYS == c when b == d

From the forum gods themselves.

My only counter would be not all engines are spun that fast (diesels). But of course, they would cross there, and failing to spin it that fast is only a 'choice.'

Actually my stock cross fire probably wouldn't have reached 5252. I think it red lined at like 4,500. Not kidding.

Not all vehicles spin to 5250, or even close, meaning it will never intersect. Diesels for one.

Posted before I saw your post. Yes, but failing to spin that high isnt a choice, some diesels would never spin that amount of RPM, ever. If they cant spin, it's not always ;)

What was the argument from minortiy report?

5252 is just where horsepower and torque will cross due to the math formula. You don't have to spin the engine to 5252 to get a horsepower figure. As Ben stated horsepower is a calculation of torque multiplied by rpm and divided by 5252. This article explains the formula.

But they absolutely would if they could. :nuts:

Goes back to my minority report joke. Unless it happens, it cant be absolute ;)
I agree with you whole heartedly though and I'm just being difficult for the means of entertainment.

Which is why I said consistently ;)

P.S. Ben, consistent isn't dispositive of absolute, the inverse isn't true though. Yes... that's a quadruple negative, winning. Now start a semantic forum category so the three of us stop annoying everyone else.

And Guy, it's always a choice. Get rid of the rev limiter with a tuner and you can spin anything to 5250, even a NA diesel would get there eventually. Sooo suck a dick. Hahaha

Even if you removed the limiter many diesels wont spin that high and/or would break something before they got to 5250.

Math is absolute by definition. You mean concrete. ;)

enkeivitte, brownie points for set analysis of terms.

Shaolin, agree, some engines will NEVER get to 5252. But if we come up with another power ratings, say, "Guy Power" that sets work and torque terms appropriately we can lower the rpm crossing to something all engines can reach, say 1,500 rpm.

I'm totally going to develop this formula. Horsepower is a bit old anyway. Brace yourselves, I'm going to use newton/meters for torque and meters for distance

Thats a mighty fine opinion you've got there. It seems to have made its way into a logical argument... poor little opinon, it just wants to feel worthy.

Not an opinion, many diesels dont see even 2000rpm and never will.

There are 900hp+ 7.3l's that dont even see 4500rpm, on an ungoverned ecu. It spins to where ever the turbo and fuel system is capable.

Guy's right on this one. I see no evidence and zero experience of any diesel engine spinning anywhere near 5,000 rpm. Engines will NOT just arbitrarily spin faster, they will self destruct or simply reach the rpm envelope of the system. Even the R12, without question the finest high performance RACING diesel engine ever built peaked out at just a little over 4,000 rpm.

I will admit when i'm wrong. This is the ONLY diesel i could find that spins above 5k.

This is naturally a one off engine and at 250psi and 4 turbos i hope it would be able to spin the 7500.

Let me say, holy shit, 3000hp

EDIT apparently it was a puller engine and torque cant be measured since it cant be loaded properly. Its best time was a 6.82 at 205mph. Seem like with the amount of power it makes it should go faster. However Adam's argument of any engine eventually spinning to a given rpm when its given time just doesnt work.

What Bitches:

I'm not seeing 5250 in that video

You have to admit that's pretty close for what it is.

Still not the argument. The argument was that ANY engine, will make it to 5250 if its given enough time.

I know my 6.4 doesnt get anywhere near 4200

Thats silly Ben. You think a diesel engine isnt built with parts at least as strong as your cute lil gas motors? Its like reving your ls1 to 8k rpm, itll start to slow way down and choke out because its not making any power up there, but itll do it. Theres just no purpose, and high risk.

You have a mental road block, but no rationale to support what youre saying.
