hey guys put my car on the dyno today at tafe and pulled 92.26KW@146KPH, teacher said thats pretty good for a stock na only mods are extractors and 2.5'' system. would put the sheet up but I dont have a scaner so i took some pics with my phone but their not that great. Some original photos have not been recovered yet.

how do you get to use this dyno man ???

is that tuned or anything or just the bolt on exhaust system? and also auto or manual? seems pretty good its the same setup as me so mine would be similar i guess good work man i want to get a dyno run just to see what it pushes out

coz im an apprentice mechanic and i go to croyden tafe they have a dyno there and we are doing dyognostics at the moment so we got to put our own cars on there and did some power runs while we were messin around on there. we can put anything on there at anytime pretty much just gotta organise it with the teacher aslong as you go there and your a mechanic you can use it nah mate not tuned or anything just obolted the exhaust on myself and put it on the dyno today pulled 89 on my first run then 92 on the second and its manual, engine 135 ks on the clock

I dyno'd mine, and the dyno machine laughed!!

last time i dynoed my vl had round 120rwkw. a few more mods have been done after that run so yeh

yeah well i only put it on for a bit of a laugh, i wouldnt of bothered if i had to pay for it but its interesting to kno the figures. 120 and its a NA ? thats pretty good what work you have done ?

what mods to get 120rwkw?

yes mate thats right, if its a na and he pulled 120rwkw thats pretty good was just curious what he is running. i got told that 92rwkw was pretty good for a stock na vl.

they come stock like 114kw don't they? How can you be putting out less power than stock?

114kw at the flywheel....

yeah 114kw at the flywheel 21 years ago, mine was 92 at the wheels so that is pretty good for 21 years of abuse.

you generally as a rule loose between a quarter and a third of power through the driveline, so with those mods hes doing pretty good

what would anyone do to a NA to get power out of it. (and im not refering to putting a turbo on it)

transfer kw at the wheel's into hp and thats what you should have at the fly wheel 92kw(123.28hp) at the wheels x 1.34hp = 123.28kw (165hp) at your flywheel so you have gained 9.28 hp for standard not bad for a 20 year old car.

yea i had my red vl dyno'ed ages ago (going back 2-3 years) and it started our with 91 rwkw and i was able to get 96.5 rwkw out of it in the end. Just an N/Z with pod filter, extractors, 2.5 inch system. This all going through a manual box.

Through a manual box you can expect to lose around 20kw so that give him about 110kw at the engine which is what you would expect.

i found the formula in street commodores going back a lil while. its lots of stuff in there like 1.34hp to 1kw 0.7643kw to 1hp i'll have a good look and get back to you

yeh those are correct but theres not really any 'standard formula' for how much power you will lose at the wheels. For 90rwkw going by what your saying you multiply by 1.34 to get the KW at the flywheel which equals 120kw, thats probably is not too far off the real figure. But what if youve got 500rwkw? multiply by 1.34 to get 670kw at the fly... but theres no way your losing 170kw through the driveline lol..
