Hey riggaP, what could be some possible causes of a low mph. I'm kinda suspecting that my boost may not have been getting to 12psi in higher gears. Could this be the problem?

:rofl:

Do you have any aftermarket engine management? If not it could be too much boost. The stock 33 ECU dumps shitloads of fuel when you start running more than 10psi. A piggy back is probably the way to go (ie SAFC etc). You should get more out of the coola too.

Not a bad time for the mods. What 60' and mph where you pulling?

i'll type out the time slip just cos i cant scan it at the moment

(im on the right btw)

Reaction Time: 0.9781; 0.7493* (time diff 0.2288)

60ft: 2.3315; 2.4162* (time diff 0.1441)

330ft: 5.9634*; 6.2632 (time diff 0.0710)

660ft: 8.9389*; 9.1797 (time diff 0.0120)

660ft mph: 84.76; 82.57

1000ft: 11.4674*; 12.7623 (time diff 1.0661)

ET: 13.5786*; 13.8082 (time diff 0.0008)

MPH: 107.71; Error

NB. * denotes leader

yeah well i didnt get a trap speed, and u can see the big jump between 660ft and 1000ft in the time differential, i thought itd be due to the stuffing up my 2nd to 3rd gear changes....

is the elapsed time wrong? if i didnt engage 3rd gear, that means my car would be roughly doing 100kph when it was time to go into 3rd, which i think wouldve ocurred between the 330ft and 660ft mark, but at the 660ft mark theres only 0.012sec diff

ah coool should be good!!

That last run pissed me off so much cos I had to race in the right lane - there was no bloody traction down that side, then after my tyre warmup they made us wait for so long - tyres got cool and just didnt hook up at all.

      Mistakes were made, my R34 Story

      (it is a brand new ported mellings pump) I suspect the lack of pressure is due to the leak. It was *not* that low in other logs of oil pressure in the past. It wasn't that hot either, but not far off.

      Would a Mellings oil pump be a viable option  From my time with a LS, and talking to tuners and LS specialists, the "weak" OEM oil pump is one of the first things they recommend to swap out if I was going to give the engine any high RPM I opted for a Mellings high volume, with the high pressure springs and I never had a issue with it Cost wise they are not expensive in the scheme of things

      My new to me M35 Stagea wagon

      By davemoto63 · Posted

      Just bought a 2002 Stagea 250tRS VR-X Four AERO VQ25DET and spent the last two weekends cleaning and detailing it.. still have to do the wheels and the engine bay but the rest of it came up nice. Imported 2011 to S.A. and I'm the third owner since it was imported. I met the guy who brought it over, he went to Japan and picked out the car, bought it and ordered the wheels. He also gave me a list of stuff he did to the car with receipts. Coil overs (I have the original springs), 3" exhaust from the dump pipe back no cat, Custom dump pipe,(I have the original exhaust), Plenum spacer, 18" custom Work XSA wheels (need restoring, I've made a start..), Shift kit put through the 5 speed tiptronic auto, TV and menus/screens changed to english, Australian DTV tuner installed in rear. I've just had four new discs and new pads as well as all the fluids including the brake fluid replaced. I have all the receipts for the last 15 years and the import papers in a nice folder. Car looks great, goes like hell but fuel economy is not a thing lol.. pics next..

      Steps to DIY sanding car back ready for respray....

      By silviaz · Posted

      I ended up in this rut again lol, and used a shit ton of filler. One thing I can't understand is, even after using a big long block and going in long X pattern strokes, I always end up at bare metal again with no filler, and my repair started at one end of the door and now I've chased my tail to almost the other end of the door. I was thinking of hitting the panel with a hammer where it might be a high spot and making everything low then filling it, I did this on a small section on my other door by mistake and I think I fixed it lol. Is this a bad idea? The other thing is with guidecoat, whether it's the powder or spray, after I sand all the guide coat off, it doesn't reveal anything for me in terms of high spots and low spots and makes it especially hard when it's bare metal (at least in powdered form), am I doing something wrong here, or likely a high spot I keep going over and creating valleys? Lastly, stupid question but, is it possible that after sanding if I only sand over the filler area where I know to be a dent that it's impossible for me to dig into that dent? Unless there are other problems which I missed.
