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

:blink: cheers :D

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

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

I cant read the time slip???

Time for some reading glasses mate!

Try this one, I touched it up a little

Great times BTW, one tough RB20!

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

The answer is;

the tyres are m/t et street

:P Cheers :D

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

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.

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:)

    • Was there ever a model of the Stagea m35 that didnt have a badge on the grill? I thought I saw that somewhere, some aero edition or something? I cant find it again? davemoto
    • Its a 2002 vr-x four VQ25DET, silver. Coil overs, lowered, polished alloys and sport exhaust. Bit of a project, was sitting in a shed for a while but runs and drives great.
    • I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.
    • Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.
    • Well they got my money but they are not getting my gearbox !
