By the way Ted B, point me to any literature showing that Shoot44 mode makes a Dyno Dynamics read like a DynoJet. I believe on the MLR a standard Evo normally runs about 210 whp on DD Shoot44.

What does a standard evo run on a DynoJet?

 

To be frank, I do not see any evidence they are making more power. They are dealing with the very same engine parts and laws of physics as are we, just using different dyno settings. It seems they are using unrealistic boost pressures considering the fuel octane, and achieving results comparable to what we see with less pressure. If this is indeed the case, my advice about ignition timing vs. boost pressure and EGT is certainly important.

 

A standard EVO VIII gives much greater than 210whp in shootout mode. An EVO VIII gives ~205whp in standard mode with a correction factor of "1.0".

 

There is no standard USDM Evo, though. 03 VIIIs make less power than 05 VIIIs and much less power than 06 IXs. On a Dynojet, you can see 220-225 from an 03 and see 260-270 from a IX. It's not always that drastic, but it's possible. We see 200-230 on DDs for the most part, but like always, different people use different correction factors and are at different altitudes with different climates.

 

Is it true that you guys in the states tend to run standard compression when building your engines so would that not mean you cant run as high boost anyway?

 

Then post drag strip trap speeds and let's see where they are.

. . . or lower.

It is an estimation bhp


Ok, now I really am laughing.

 

Ted the car in question in this particular thread is using a MAD spec 2.25 litre engine, MAD cams, and I think a Kansai inlet manifold on 99/100 RON fuel which we've concluded is about 95.

So there is a lot going on here that is not necessarily exactly what is going on in the states, or maybe it is. Who knows?

I'm just saying before dismissing the result, might be worth considering it as plausible for a moment.

Warrtalon, I understand what you mean about diff spec evos etc. I was speaking evo 8 and earlier and just making a rough average.

Guys, FWIW I'm pretty sure Shoot44 removes all these correction factors if I recall. Someone more knowledgeable than me will explain on here soon I'm sure.

 

when buying a car they always state crank horsepower as in the evo9 ita makes 286bhp,so i assume they take the engine off the dyno engine and just put in the chasis? why talk about load and all that stuff or does it mean that car manufactures put more bhp on the engine dyno but claim less?

 

I just confirmed it via telephone with Andrew of Dyno4mance.

Typical indicated power for a bone stock EVO VIII on a Dyno Dynamics in shootout44 mode is 260-270whp (most often 265-268), and shootout44 mode is indeed intended to represent an estimation of flywheel power (bhp). Obviously, it seems to be about right in this isntance.

This should put a great deal to rest.

 

Is there perhaps a diff between shootout mode and Shoot44?

I might have mis-spoke when I said shoutout. I do see on graphs on MLR it says Shoot44 on bottom.

 

Ok guys here are 2 more UK cars running gt35's

Note all in Shoot44 mode and let me tell you those don't look like flywheel numbers Ted B!

 

Hi Ted,
With all due respect (since I've read your posts in the past, and you put up a lot of good information), I'm not sure you totally understand how a typical strain-gauge based engine dyno works. In order to read the maximum torque for a given RPM (and thus determine the maximum power at a given RPM), you need to put the engine under the maximum load it is capable of handling, while maintaining that RPM. An engine on an engine dyno with less-than-maximum load applied to it, will show less-than-maximum power. The reason for this loading requirement, is that an unloaded dyno cell doesn't provide any force for the engine to work against, and thus no torque is applied to the strain gauge.

Because of this, your argument that they reduced load on the engine to escape detonation doesn't make much sense. If they reduced the load, they would reduce the power output shown, and you wouldn't be seeing high horsepower numbers. If any of this didn't make sense, let me know. I've configured engine and chassis dynos from the ground up, and have some experience running engines on SuperFlow's engine dynamometers.

Thanks.

Alexander

 

There is a huge discrepancy then, as my Evo IX FQ340 with 345 BHP as claimed by Mitsubishi did 258 WHP on Dyno Dynamics in shootout mode. It is quoted as WHP. As noted, standard IX does about 210 WHP.

Mark Shead will have to produce his own drag results for you, the 200 mph Cosworth is some feat though on a 2.0 litre engine. You do have to realise that most of the UK tuners are not terribly interested in drag racing though.

 

Dont worry about WarrTalon, someone let him out of his cage. No many of us take him seriously.

This is correct, and very well noted hence why if you in a higher alttiude than your going to have a harder time making power.

and For the Win.!
