OLD Dyno Leaderboard Top Twenty

correction factor of some sort

[Guest]

AFAIK

TCF is the torque correction factor. It converts from the wheels to the flywheel torque.

If its set to 1 then there is no correction so its measuring at the hubs. Presumably you could only "fool" the at the engine figures ?

There are other ways to get "good" dyno figures as well.

yes..

simply by altering the "ratio" figure will make the figures go all over the show.

Rick (ichi) started explaining this to me the other night but i glazed over pretty quick,

*waits for him to come and explain properly*

[Guest]

Its my understanding that Yellow is worth 10kw @ the wheels

[Jammasta]

Yes you can twist your dyno reading, anyone remember MR X's 301 KW std (ish) Imprezza lol.

198KW @ 18psi Ver 5 STi Type R

FMIC, New Fuel pump and Reg, 3in from turbo back exhaust, Link+G2. No dyno sheet available, but for those interested.

Lol i should post my dyno sheet from Apet this morning. I make 316Nm of torque from 1500rpm all the way to the limiter. FROM A NA 2.2L!!! this has to be some kind of record!

I'm a little suspicious of his dyno readings today.

76kw wasn't it?, yeah he had probs with the dyno early on, i think its about right tho as have done some more mods since the last time i was there and got a slightly higher KW reading.

[Guest]

78kw actually!!!! that works out just up on factory spec for a 2.2, maybe a 5kw gain with the exhaust and stuff i've put on. its just the torque delivery and shape of my graph which made me a little sus on the accuracy.

Yeah he had a hard drive issue with the computer running the dyno before he even got started, his brother got it worked out so he could use his laptop with the appropriate files copied to it.

I buggered off after my run cos i had places to be, i ran second and made a early exit.

yeah i dont think torque is converted to flywheel measure, http://www.clubsub.org.nz/forum/index.php?topic=1835.msg19136#msg19136 my torque is 700nm+

[Guest]

Yeah i realise it's un-corrected at the wheels, as is the Kw. It's just that the graph shows a virtually flat torque curve. i produce the same torque at 1500 rpm, as i do at 4500rpm.

I figured it would have some shape (curve) and not be constant through the rev's :-\

Thats because you don't have a turbo to bump the torque up as boost raises, meaning no lump.

[THUNDA]

It would cost more than my car is worth to put it on a dyno but it will still strip SILNCR thts for sure HA

[driftrex]

look slike i qualify to get on here now :-)

Make : Subaru

Model : WRX

Year: 1996

Name of Dyno : Total Performance Hamilton

Date of run :29/04/09

the best run was 167kw at 14.5psi :-)

mods: sti-ra ecu, td05 turbo, external wastegate, adjustable fuel pressure. also still had the catylic converter(175,000kms) fitted so fairly restricted, guy told me my numbers are very good for what it is.

[Guest keltik]

Almost looks like clunts tune.

My GT was misfiring and backfiring and many other kinds of firing and had a nicer curve than that

yea the guy said it was the sti ecu thats putting all those bumps in the curve, been told i need a link or similar. still tho cant complain really for a wrx with all standard parts.

Thats pretty good. I was doin 167kw with a link and fully forged but a stuffed vf22.

Be interesting to see now i can twice the amount of boost.

I don't realy have any upto date pics but this close enough.
