[caspros]

Yes indeedy !

[Guest]

Yes indeedy !

wow thats pretty imprssive - what psi?

[GC8E2DD]

Hah Chris, now you just need to find some grip ;]

[caspros]

Ha ha yes yes I know. Shall see what happens this weekend !

Edit: Sorry, 18psi I think. Ran out of puff after that.

[Guest]

well done nice stats!!

[funkytown]

i havent got my graphs scanned yet, by on the same dyno as Chris

235.7kw atw on 18-19psi. high flowed vf23, pump,555cc injectors, FMIC, Link G3, fully forged block

[Guest]

cool will await the scan

good sir

the boost looks like it dies real fast.. the graph is a little squashed as its paired with AFRs... given boost does drop - its just not as bad as it looks

[Optical]

what does 'high-flowed' mean wrt the vf23?

seems pretty laggy, 1bar@4200rpm? My old vf23 hit 1bar at about 3400rpm and made about the same power on 16-17psi....

[funkytown]

means the wheels have been changed, cut back on exhaust side and larger compressor wheel.- ported on exhaust side,

It is a big laggy on the dyno - reasons unknown at this stage. On the road tho it doesnt feel that way at all.

I do have aftermarket headers in there which are larger than stock so that is part of the prob to i would guess.

My vf23 before the work was real sad and making fek all power circa less than 200atw..

the highflowing is a Steve Murch term simply

edit: check this out optical... http://www.trademe.co.nz/Trade-Me-Motors/Cars/Subaru/auction-263854344.htm a 23 only making 220 at 20psi, looks possibly "highflowed" as well with the larger compressor wheel..

Not sure If this question has been covered, or if this is the correct place to pose the question but here goes:

What is the story over inflated Torque figures on dyno graphs?

Some of the graphs show cars making 700+ nm of torque while others with the same power are making 350 - 450nm.

Now my question is that if gain/correction method or what ever they are called on the dyno are adjusted and the result of this are the high torque figures does this mean that the Power figures are also higher than they should be too?

[Guest]

The high torque figures - are torque at the wheels not the engine.

Hi, everyone below me can move up a notch, sold the car

[Guest]

Just finished off my V7 sti, got a few minor mods done like the usual fmic kit, exhaust, intake, split fuel rails MSE hybrid vf turbo unequal length headers, also my exhaust is a jasma system with a 2" restriction through the muffler to keep it quiet so i am loosing top end power finially got to getting it tuned and it makes 237.7kw and a crap load of torque on 19psi at about 6000rpm, running about 90% injector duty on sti pink top feeds,

this is a factory motor done 102000km

i will post the dyno sheet once i get a chance to scan it at work

[Pappu1]

what turbo u using bro? thats some good gains on the v7 sti setup. based on ur injector duty cycle, how much AF ratio u running?

im hitting 85% max on injectors but running like in the 10's af ration

also going thru the dyno thread i notice many of the graphs have af ration in 11's and some of them even in the 12.5 region on the top end ???

isint that a bit unsafe with imminent set of knock?

[sultan]

depends on the temperature of the intake charge. if you have a well-working cold air setup, good intercooler setup, and turbo that is operating in its efficiency zone, 12.5 is very safe.

[Pappu1]

on raod cars i wud think 11.5 would be the safe limit given bad batches of petrol could cause issues at 12.5....

maybe if apart from engine even fuel was controlled then 12.5 could be safe... thats just what i think anyway

12.5 is perfectly fine.

I personaly adjust afr to the amount of boost running.

around 13.5: up to 4 psi

13:1 up to 7 psi.

12.5:1 up to 14psi

12:1 above that.

Have never had a customers car returned with issues from tuning.

[Pappu1]

i always go 11.5 after hitting full boost as a proper safety measure.. see some loss in kw but rather play it on the safe side

factory usually stays 11.0/11.1 mostly

how do u get afr to get inline with boost?

the tables are load based from wat i see....or m i missing something 8)
