Dyno Run!

[Fugi]

197kw might be a nice reading, but lets see how long this engin can cope with running lean...

[r32matt]

Yeah im going to get a new Fuel Pump very soon. Then finish the zorst off with a 3 inch Front/Dump pipe and Hi Flow Cat. Raise the boost to 14psi and get a tune. Should be sweet then

[WazR32GTSt]

thing is.. according to the dyno graph, it only runs lean up top, and by then its already made most of its power...

so its power isn't really coming from the fact that its running lean...

in other words, the rb20 is makign power for another reason. because its just in really good condition? possibly..

rb20 ftw!!!!!!!!!!

where's Roy? he'll jump in here soon for some rb20 lovin

Thats pretty good Matty boy! Now take it down the drags

[NathR32]

Shit, thats a good result Matt. Good work man.

Looking forward to SAFCing mine and posting up results soon. Won't be as good as yours though

[123456]

demit, how come i get 167, with more mods, on 14 psi, on a engine that so many people have told me is in really good nick.

Rb25 time i suppose

Nice results

[andylaurel]

thats lean

13:1 is rudely lean

[Bunta]

Take it to the strip and tell us the MPH...that never lies

[r32matt]

Yeah it is running lean but the power is still up there before it starts running lean...

I might get some new tyres next week and take it down the 1/4 Mile

Yea well im so glad to see a rb20 with those results. I own a rb20 my self and have basic mods and bout a power fc and one of those turbotech BC try it out and get it dyno'd.. but yea i dont think i will get those results ill post them up. i think your one of those guys with freak engins. lucky c**t.

MATT nice work and it does look at 150km's you hit the limit of the fuel pump, BUT there is a posible little thing you can do to help will the fuel pump until you can replace it. That is to run a good heavy gauge power supply wire to your fuel pump as the standard system normally has to much volt drop across it (meaning your not getting full 14v charge volts to the pump) you can use the exist power system to switch a relay controlling the heavy gauge if you like and also ground the pump well. This is not a total solution but can offen gain quiet abit of exa performance out of the exist pump and will definitely help went the new pump going in. (voltage to torque ratio is a square root relationship meaning a little voltage drop will lose a lot of torque).

As for be lean BS running 12:1 through the majority of the power range is great and safe, and at only 12psi you could quiet easily run leaner without a problem. The only problem is the lean out trend at the end as you have already identified.

pete

ps i run 12:1 at 500 to 530rwhp for 2 years at 18 to 20psi no problems.

wouldnt 197rwkw be past the limit for the AFM and injectors?

[fr0st]

wouldnt 197rwkw be past the limit for the AFM and injectors?

The RB20 MAF is good for ~220rwkw, Injectors are 200 ish I think.

Nice result! I pulled 195.4rwkw in my 32 and thought I was doing well... but you don't even have a fuel pump or tuned ecu!! Must be happy about that.

yeap, and you must be happy about the wanker dyno operator giving you bullshit figures.

Unless your factory ECU has been remapped, and the turbo either high flowed or replaced with a RB25 turbo, then your figure is bullshit.

I bet any of these "figures" are barely able to pull over 100mph down the quarter.

[kamakazi]

ok matt is running an r34 steel wheel turbo and i was there it did pull that power and have been in the car and it feels as quick as mine, i have an r32 with an rb25 making 197 rwkw. i have no doubt that the dyno is reading correct

It was also run at the pole position dyno day so i doubt they mucked the figure up when my car was run before matt and a soarer ran after matt and power figures for both my car and the soarer were around what they expected.

Mafia it sounds like your really f**ken Jealous of my RB20! Just becasue your RB25 wont produce that much power on those mods doesnt mean you have to have a cry!

And if you actually READ! I wrote that I have a R34 Turbo!! How about you put up your Dyno reading and your Mods and lets see what you get?

Thats an awesome result. Must be a relatively fresh engine. My question is how much difference in power output could there be between a fresh engine and an engine thats starting to get tired? In fact i started a thread about it!

Your questioning Hyperdrive's (im guessin as its in Malaga) dyno??

It use's shootout mode and is known as a very realistic dyno, doesn't read high at all dude.

Its well known that shootout mode applies some exceptionally poor correction making results higher than they should be.

demit, how come i get 167, with more mods, on 14 psi, on a engine that so many people have told me is in really good nick.

because yours is realistic dude

I'd reckon you both would run extremely similar times down the track...

And same dyno same day, you'd both have power figures close to each other

Im going to the drags very soon and when I get my quarter mile time it will give you something else to cry about!!!

He isnt having a cry about anything and he actually owns a rather quick car and knows what you need to do to achieve that sort of power... He is being realisitcs considering your modifications. So either there is more there that you are unaware about or its possible the reading is incorrect.
