Top RB20 Club... do you have over 260rwkw?

[Rolls]

520 thats like 375rwkw

Are you for real?

[carl h]

hehehe, 520rwhp out of an rb20 has to sound insane on the dyno as well as on the street.

i know that in my car with the open gate when boosting 17psi the car sounds like a serverly pissed off supra..........

[Sydneykid]

hehe, yeah there is a place here stateside that will test oil for whats floating around in it......

yeah im using the emanage to fork with the maf signal (which it does do well) but since the ecu has an agressive timing map (actualy on the ecu) forking around with the maf voltage makes it feel terrible if i do it too much.

if i dont use the emanage to correct it runs too lean due to the timing map...... so its a catch 22 untill i can get the biki rom where i can see where i am on the maps.

there isnt that much correction on the map like +10 pts which isnt too terribly much but its enough to fork with the signal enough to really make it feel weird.

from what it looks like i might be able to get full boost at 4k assuming i can add fuel in the right spots (which i cant do with the emanage right now) and it should have a fairly beast/wide power curve if i can get it that way......

i will let you guys know my results tho for sure, because once the car spools its frightenly quick.

OK, so what you are doing is richening up the A/F ratios with the EManage, this retards the igntion timing and so it feels sluggish. Unusual situation, 99% of the time we are trying to lean out the A/F ratios by bending the AFM output voltage.

What I would do is increase the fuel pressure (adjustable FPR) so that I didn't need the EManage to make it richer. I would adjust the fuel pressure for 12 to 1 A/F ratio at the max power RPM. Then use the EManage to tune the other RPM load points. This will remove the need for large amounts of voltage bending by the EManage and retain some semblance of normal ignition timing.

If I couldn't get the injectors to flow enough at the higher fuel pressure to achieve the 12 to 1 A/F ratio , then chances are the injectors will be too small regardless of what ECU I am using. So upgrading the injectors is the next step.

Hope that was of some help

cheers

Hi Guys Ran my R32 gtst with a friends R32 both rb20dets just thought you'd like to see the results first time ive run at the drags in over 25 years and yes im on old fart but going fast never gets outa your system anywat clutch started slipping on the next runn so had to call it a night might have gotten better with a bit more practice

Cheers Peter

[Cubes]

What sort of power are you making legend?

All on the stock rb20 g/box? Those tyres look they would much it.

[yogi000]

ur top end aint that great but your 60 footers are awesome

i had 207rwkw on tap and was doing 2.2 60's and 108mph trap speeds

[legend01]

Hi Cubes

Power is 238kw and running rb25 box and the tyres are m/t et street drove there and back with them on

Yogi000

the turbo is still the prob at the moment runs out of flow by 6800rpm new turbo on order Gt3040r that will improve the top end hopefully

Cheers Peter

[Waldo]

wat size exhuast housing did you order with the gt3040r

[legend01]

Hi waldo

the .82 its the housing im waiting on garrett "say " they dont have any in the country at the moment

[Roy]

I cant read the time slip???

[Chris32]

Time for some reading glasses mate!

Try this one, I touched it up a little

Great times BTW, one tough RB20!

[Butters]

1.6 60ft !! Damn !!

I assume thats slicks ?

[Roy]

Damn...im running more mph but 6 tenths slower...lol i can t drive my car off the line for love or money:(

[Sydneykid]

Damn...im running more mph but 6 tenths slower...lol i can t drive my car off the line for love or money:(

<{POST_SNAPBACK}>

The answer is;

the tyres are m/t et street

Cheers

[legend01]

Hi Guys

both cars are R32s both rb20dets mine's running the et streets the other was running Hooser semi slicks

Roy

I ran higher mph on street tyres but 1.5 second slower times

i think it might have something to do with tyre dia as the m/t's were 26x10.5x16 "si just fried the street tyres 1st ,2nd and 3rd

Cheers Peter

[Roy]

LOL...he is about 6 tenths quicker at the 60ft time and only 6 tenths quicker across the finish line. Based on what I read then with a 115mph trap speed and a 1.6 60ft time then an R32 should be able to do a high 11?!?!?!

...cool:)

[legend01]

thats what im ai ming for next outing :-)

[legend01]

And if i get that might just squeeze into HPI's top ten in 2.4 and under ?????

Yeah baby ! go the rb20 :-)

[Lithius]

Hey legend would you mind posting up what modifications you've done to your car to get it to 238rwkw? And also your mates car if you know.... those are some awesome times. Very impressed with that 60ft time from a rwd.

[Roy]

Please run an 11 on a stock RB20:)

I cant recall reading if you are using the std gearbox? What clutch and diff is in the girl.

After the last track day in late October i want to hit the drags, my housemates poo RB25 thingie ran 0.1sec quicker then me, (but 3mph slower) cant have the quickest car in the house being an RB25:)
