I had to do pdf because of my granddaughters PC down here in Florida. I promised to a few people that I would do it on a dynojet. These are the results. I was told these were good numbers despite the heat. It was hot as hell down here when I had it done. I will have a new dyno done in Oct. in NYC when the temp. is cooler. This is a question for the members. If the whp is 221 what is the hp at the crank? Thanks in advance Warren

 

I think is around 271hp Warren..

 

So I guess that's assuming an 18.5% drivetrain loss... is that what the 6th Gen ATs are seeing? Seems low to me... I woulda thought it'd have been around 20-22%.

221 x 1/(1-.185) = 271

 

Looks good Warren!! It does look like it was pretty hot during the Dyno, the readout says 100+ degrees as the temperature. Gotta love Florida! Anyway, way to go! PEACE

 

I did it with 23% loss....


221x 18%= 260............. 221x 23%= 271

 

your math is wrong. crank would be around 290 b/c 287 - 23% = 219.99

you have to take the 23% off the crank not add 23% to the wheels.

Warren, you should post your mods so people know this insn't stock.

 

ah I see.... I did add the 23% to the 221hp, and you can't do it like that..

so it is about 288hp at the crank Warren.... my math was way off...

 

Ok for the members who don't know what my mods are.

Wait a sec... drivetrain loss is applied to the crank hp isn't it? So you'd take the crank hp number and apply the percentage loss. For example, a stock 6th Gen is advertised at 265, so you'd do:

265 x (100% - 23%) = 204 whp

Working back the other way:

204 / (100% - 23%) = 265 chp

So in Warren's case:

221 / (100% - 23%) = 287 chp

 

Do you by any chance have the real dynojet run files?


Also, I noticed you only reved to 6200.

 

Okay... I didn't see that NismoMax already responded... haha... the F5 key owns me....

 

whats a "warren" mod?

nice numbers for the weather. Is this on stock wheels?

 

wow our numbers look really close. what gear did you do your pulls in. specifically what gear were you in when you pulled a 253 torque?

 

He has the 5AT, which IIRC noone has the calculated loss figure for (IE, nissan has not released that info yet). I suspect, however it should be just about the same as the 4at.

and the correct way to derive crank #s from wheel #s is to divide by 1-%loss...so 207/.77 = 268.83chp

 

yea, you kinda have to figure out the crank hp, then minus the 23% from that to get the 221 wheel hp...

the math has to equal 221... so its 288- 23%= 221hp..

 

thats G14 classified.we cant tell you.

 

PS: warren, can you email me the runfiles e55amg2@gmail.com

 

Thats me stepping on the gas pedal. lol


18" crome wheels.

 

287/.77 is the correct way

 

my algebra is rusty so that's how I did it Tek. I tried the right way how E55 just showed and gave up when my head started to hurt

221/.77=287

So if we get a 5AT dynoed and it's close to oem spec #s then with his above mods he gained 22 hp crank.

I so wished the RedlineMax meet would of had a dyno like originally planned. but w/ 130 maximas, we would have been there all weekend.

 

CF: STD Smoothing = 2

 

then what is the Max power = 219.xx??

and on the graph 221 is written?

I'd get mine dynoed, but I'm awaiting my JDM nismo hood banner from Japan. It adds 35 to the wheels!

 

you think the headers will put us over 300 motor hp, not crank..

 

bah, i mistyped it should have read

WHP -> CHP = 221/.77
CHP -> WHP = XXX *1-drivetrain loss %

 

Wait, did you mean 287 x .77?

 

Yes....but i managed to type it wrong.

 

Gotcha... so my post was right...

 

ok, now I have a headache........

 

what do you mean motor hp

 

yes, and we have managed to give tek-niq a headache in the process...Id say we have accomplished our mission

 

without all the losses... I guess that would be crank right.... I'm all f-up


thats why I make my car look good instead of making it fast....

 

I threw my caculator into the woods behind my house so all I'll say is, Looks good, Thanks Warren for doing this for us...

 

LOL, did the calculator anger you?

 

No, these dudes where posting numbers back and forth so fast, I deemed it useless and tossed it...

 

Good numbers Warren - thanks for getting the dynojet done

 

Yeah, thanx Warren! My car has the same mods yours does, so I would expect similar numbers.

 

Well done mate , looks good to me .. what fuel were you running ?

 

I want to thank you guys for your comments and the answer to my question. I was running 93 octane.

 

well if all goes according to plan and fixes my screwed up a/f ratio like i think it will then i should be close to 300 crank horses.

 

[QUOTE=SR20DEN]Do you by any chance have the real dynojet run files?
The above are the slips that the tech gave me. So I don't know what you are talking about.


Also, I noticed you only reved to 6200

I quess the tech didn't want to run it higher because of the weather.
