My 164rwkw Dyno Run Scanned

[Cubes]

Here's the dyno run that was done in 4th gear at RPM.

Makes top power at about 6k im guessing with the turbos running out of puff, good result though.

I might ask Tim where it makes peak power.

So the turbo running out of puff is where the power curve flattens out at the top then Tim takes his foot off and the power curve drops?

[kjb_r33]

no, power curve will always drop, hits a peak then drops off as the rpm gets higher.......

[Cubes]

What causes the power curve to flatten out at the top?

[adam 32]

what AF ratio were you tuning it to?

and what management are your running?

[Cubes]

Adam.

The ECU is all standard, I havn't got any engine management for fuel/Timing etc..

I use a bleed kit on the fuel pressure reg to help lean it out a little.

It is a pretty crude method to lean the fuel out but it seems to work, The afs arn't pefect.

i.e if you make the af's perfect up top then the mid range will be lean and loose power, make it perfect in the mid and the top end will still be slightly rich and loose a little bit of power.

Works ok but.. Its good for a tuning tool while you are getting you mods done. Then the ECU re-map will be done.. AFTER.. the new turbo..

:confused: Hi guys i'm new here and i was wondering if you could translate 164Kw to me in horse power or teach me how i can do this myself being that im from Jamaica i am not use to this.

the power curve angle, how long it levels out and when it drops off is pretty well determined by the cam. Duration, lift and overlap...

l¥le..

164 kw is 219.9 Hp, and that was at the rear wheels...

yeh cos i made around 165rwkr at 12psi tuned like a dog. am looking at some tuning options at the moment, probably just go for a remap though. its just so damn expensive!!

to equate kw to hp (roughly) times by 1.34

so 164x1.34=219rwhp

[Cubes]

Remap Expensive..

$500 isn't expensive well if its the last mod you are doing its not..

[adam 32]

$500 every time you want to tune the car is pretty expensive

well at the moment im running stock injectors and a bigger pump so i think i might remap for 1 bar.... i cant afford injectors atm so depending on the results this may be the last mod for a while...

is there such a thing as "the last mod...." ?

Hey Joel....

When u finally put your new turbo on if u overlap the dyno readouts your new one will be slightly slower to make horespower but the curve will be more vertical andovertake standard curve. instead of flattening out at the end it should keep rising only just dropping at the end of revs where engine runs out of steam in that gear
