Dyno Run With Kkr430 Turbo

[Simon-S14]

Got my car dyno'ed today... its been a long time due, and with the issues i had at the recent G1 comp (ignition cutting out) i took with me spares of everything, AFM, CAS, Ignitor etc to swap it over.. but it turns out that the ECU is a bit on the dodgy side

I always thought i had a stock map on my ECU.. but turns out that its been remapped in Japan, whoever did it, certainly likes their taste for fuel, as throughout the whole midrange (4000 - 6000) rpm the fuel mixes were off the scale and mega rich (off the scale being lower then 10:1) Couldnt believe it and neither could jeff... so he went to work taking out all the fuel, adding some timing and so forth. Took a few runs and due to some weird as ECU related issues, we wasted a lot of time and chips and so we were cut short on the dyno time.

My main goal was to increase the midrange torque and so forth, i wasnt really fussed about the top end power as much, as i was happy with that and i didnt want to run anymore boost then i already was. So with the changes to the map we were able to get phernominal torque out of the RB20 around the 4500 rpm range, the KKR430 comes on HARD now and basically the torque curve in 3rd gear is near verticle, in 4th it is equally massive. several times the car tried to climb out the dyno... crazy!

Final figure was 197.4 rwkw's on 1 bar boost, Runs were done in 4th gear.

I have taken pics of the dyno graph, however Jeff is going to be changing this in the very near future to smooth out those midrange mixtures some more.

All in all im very happy with the results.. On the road it basically translates to massive wheel spin when i floor it in 3rd and even more wheelspin when i grab 4th

Big thanks to Jeff from The Speed Lab for persisting through all the related ECU and chip drama's and Steve from jazmac for helping out and the Dyno hire.

Pink is 3rd gear and Red is 4th gear... Keep in mind that power and torque figures are accurate in 4th gear...

thats awesome!

im looking into getting one of these turbos fitted on to my line

awesome dude

[Simon-S14]

i couldnt reccommend them any higher... for the money they are awesome turbo's

see sig for KKR contact

Cheers

does this turbo suit the rb20 really well? iv got a rb25 in my cefiro n been lookin at this turbo heaps, how you think it would go with the 25? also how much boost are you running?

thanks

[Simon-S14]

1 to 1.1 bar depending on weather

and yes, it will be perfect and lag free on the RB25... it suits the rb20 very well and there is minimal lag, plenty of torque and top end too!

[cohen20]

hey mate just wondering with the kkr 430 have you been told how much boost they can take and how much did you get yours for thanks

Do you want an honest opinion or a pat on the back?

PM me if you want the honest opinion off the forum.

Looks like a good value for money result.

cheers

From thier own website

KKR-430

Intended for 2.0–2.5L engines, this turbo features a T3-size exhaust flange. This makes it an ideal upgrade turbo for RB20DET and RB25DET engines*. Rated at 430hp, it is suitable for drift and street performance applications, where minimal lag is preferred. It uses a 2.75in V-band flange for the exhaust outlet (V-band and flange included).

Tested on an RB25DET at Panther Aftermarket, it produced 230kW at the wheels with only 11.5psi of boost. The standard internal wastegate is designed to hold 11–12psi.

230rwkw/11psi/rb25 - doubt it

thats just it, people feel the need to make opinions because its a cheap turbo and bush bearing, but at the end of the day it makes power and it costs bugger all doing it.

id be curious to see how it overlays against a stock turbo dyno run

[Cool Hand Luke]

wheelspin in 4th with 197rwkw?? Do you have granite tyres??

[R31Nismoid]

Or a turbo that doesnt deliver the power at all smoothly

I was thinking the same thing. I spin in 3rd when planting my 400rwhp datto with 195s and stupid camber......but with 350rwhp I hardly ever did...not to mention the 280rwhp you have. No offence but whats the go?

Get those af ratios to 12 and youll be making more poke.

Well done but do as above and enjoy more power.

Edit:amaterur mistake. Seems reasonable, encouraging result.

wheelspin is provoked by torque delivery being so sudden rather then peak power figure. and yeah the tyres on the back were a bit average, 235/45/17's however poor quality rubber.

[lwboosted]

how much torque does it make??

Sydneykid, feel free to PM me your honest opinion

But the gradient on your torque curve doesnt look that aggressive...sort outthat rear wheel alignment and i doubt you will have the wheelspin problems you describe...but wheelspin is funny.

[Abo Bob]

I think that's because it's accelarating from a low speed. If he was at say 4000rpm in 2nd gear even throttle then planted it, the boost would come on quickly after a second or so whereas with a bb turbo it would be more gradual resulting in less wheelspin.

That's how it looks to me anyway. I have driven a car the same as mine with a KKR turbo and that's what it feels like.

[Simon-S14]

Ive driven a number of turbo car's, and the KKR comes on in quite a rush compared to some.

either way. its makes the power, and theres plenty in it once the AF ratios are sorted
