Got my car dyno'd

[Lith]

I have to say this..


maybe the speedworks dyno is up the $&#$%.....

Cause last week i got only 115kwish at 6grand (was still heading up at 6 tho, but we stoped it there) on my 4agze turbo.

And if you reckon you are even with blacktops, maybe you are higher than the dyno shows... cause i sure know my car is quick....like more than 115ish quick.

Well, the Speedworks dyno is pretty much on par with the Speedtech dyno in Wellington - so its comparable with other dynos of the same sort. This is backed up by a Mates Integra which consistantly puts out around 185-190kw @ wheels on 8psi on Dynapack hub dynos, one run done at Speedworks recently and another done at Autosalon on speedtechs one.

It seems that your car is probably 115ish kw @ 6000rpm quick... bearing in mind it'll probably make a bit more with a few more revs.

I have a BIG query....

why is it done in a gear that redline can't be reached?? (the point at which top power is made)

70kw is probably correct at 7000rpm. but at 7800 or 7500rpm whichever is the redline, i'm sure the power would be higher

thats really got me confused, its nearly as bad as dynoing it at 4000rpm, whats the point...

I could be completely missing something here tho...... but in my opinion, unless you are going to get VERY close to redline on the dyno, in a 20v you aren't going to know its peak power.

Ask for your money back, they didn't give you what you paid for imo

thank god its getting a turbo

yeah, i'm sure your car would shit all over it wouldnt be throwing stones in that glass house of yours

Good point Luke, looks like they did the run in 4th gear. Your not going to redline in 4th on a dyno if you have 180kmh speed cut.

Like he said, take it back and tell them to do it properly, they have an 8000rpm redline, tell em to use it otherwise its pointless.

IMO you should be getting close to 90fwkw

[blackie]

peak power would usually be reached before redline on most cars with standard cams would it not..

[Lanius]

I was wondering the same thing ...

My engine redlines at 8000rpm, peak power from factory should be at 7800rpm, peak torque at 5600rpm. I'd be a bit miffed if I went to find out what peak power its putting out, and they only rev'd it to 6000rpm

Maybe they just didn't know that the engine is supposed to be rung right out ... ? *shrug*

[aesc]

Umm not 1000rpm before redline though, unless you own a gtz

there is a trick so it doesnt lose the 2psi

Thats kinda funny, cause my car probably would shit all over it (if this 70kw at the wheels is correct, which it appears not to be)

last dyno i saw of standard smallport (except exhaust) was 86kw at the wheels, mines a little less standard than that

oh and my car weighs 950kg

so yeah

suck my balls

Is it the ABV mod? If so, done it If not, tell me more

[Malcolm]

I would suggest not comparing dyno results unless they're made on the same dyno. I've seen standard bluetops dyno at 80kW @ wheels, and there's no way they'd be more powerful than a 20v.

Usually dyno pulls are done until power starts dropping or the rev limiter is reached, revving to 6K on a 20valve is retarded, maybe the guy is used to dynoing v8s? Its like measuring your cock when flacid - doesn't prove anything worthwhile

that prob is the one

[trueno_20v]

i think they stopped it at 7000 because the tourqe was dropping?

[RomanV]

Despite the fact that it looks to almost be climbing again, and your HP is still pointing upwards?

Get it dynoed somewhere else, somewhere more competent, preferably.

[Bling]

i think they stopped it at 7000 because the tourqe was dropping?

possibly true, doesn't really apply to 20vs tho as everyone knows (the torque thing)

probably hit speed cut tho as 172 could be 180 by the speedo, sop you're really missing decent bit of power because of this

but hey, at least the increase after turbo will be even more impressive

[Malcolm]

usually torque drops well before power does, as power is torque X revs so provided the torque is dropping slower than revs are rising power will continue to increase

[trueno_20v]

yea it does look like its still climbing, i know that when you rev it up to past 7500 it dies (vvt turns off) they could have atleast reved it till then..

[Malcolm]

btw, don't even bother looking at that torque curve, its not even close to the power one. The torque curve should be a relatively straight line judging by the power graph

anyway, on the bright side you can claim your 20v makes more torque at 2000rpm than a 2jzgte makes at its peak

[trueno_20v]

on the video you can hear my car die out so no point pushing it more when its like that anyway????

[Dell'Orto]

When we dyno'd GT Girl's AE101 FX GT it made peak power at around 7400rpm I think, may have been slightly higher. I dont think Brent is very familiar with Toyotas, hence why not revving it right out, unless it was pinking at that point. I know he refused to dyno one car around here cause it was too noisy (VVT pulley rattle).

[Mr Revhead]

ppl who diss 20vs have no idea.

mine made peak at 6800 when revved to 7600
the sard ecu made peak at 6300 when revved to 8400
however the dyno we use was even lower reading than that one
