haha I'm here! Yeah, Noel and Mike are spot on. Im stretched a little thin atm. However I have fixed the issues I had on the dyno the first time. Its just a matter of getting time to go back to finish off the tuning. Currently fabricating a whole exhaust system on my old mans HR holden w/ stroked LS1 to 383CI, then I have my uncles 56' chevy to fit new 434CI stroked small block into and fab up exhaust system and fuel system. After that is Dads 57' chevy which a 632CI BBC with a 4L80e box to go into it and then exhaust system and fuel system to suit. The two Chevy's need to be done before April for a charity event we were hoping to attend at Harry's.

So my car has gone on the burner again until further notice unfortunately! If I get some time in the next couple of weeks I will attempt to get it tuned!

Sorry to say fellas that I ended up quitting on this. I did finish it and got it all going, but it was an absolute pig to drive. I couldn't get the change over from off boost to on boost with the bypass valve to work very well. I spent a fair bit of time trying different valves and setups trying to make it more drive-able. It was just taking too long to try and get it to a level where I would be happy with it.

My apologies for the disappointment peoples! If I had more free time and absolutely no social life or girlfriend then I would attempt to perfect it all, but this is just not feasible. I really hate to be a quitter...its killed me a little on the inside not being able to get it all to work how I was hoping. :(

Anyway. the car is on the back burner at the moment. The back up plan is to go to a big single and just pump out some laggy horsepower for fun.... of course when time presents itself!

How does every other supercharger in the world work then, they don't seem to have any fancy things to make them idle ok, do they all just have a low speed air bypass valve or something?

Even if you just wired a recirculation line with a very small bore eg 1/2 inch from the intake to the discharge this would recirculate air at idle and at high boost would only recirculate a little bit.

    • Welcome.  800hp should be a bit of weekend fun!
    • I'm going with "Just run two gates". Fix the problem conclusively. It's the only way you'd ever truly know, right?. This is all pretty much splitting hairs. Even the extreme example where it takes two whole seconds at 100kmh or something sounds monstrously dubious. And anyway, when you're punching the throttle when you 'need' this power, you aren't at 2800rpm in the wrong gear. Test it at 5600rpm in 3rd gear, when you're traction limited punching out of a sweeper. Much difference there when you account for traction?
    • And the full R32 GTR wiring diagrams are also freely available. Hmm.... there's supposed to be an auto replace that would have linked the thread. Here it is, manually  
    • Ahh...should have been clearer ~ there's 2 ... SMJ = super multi junction (connector)...   ...this is connector 6 & 25 in above image -- body harness to engine loom (6) & body harness to main loom (25) Headlights go to front via connector 6 ; fuel gauge goes to tank sender via connector 25  ...like I say this is R33 diagrams, but at a pinch R34 won't be too far different. *IF* the two ground faults are related, this can be the only place where both wires converge (as one runs to the back, the other to the front)... ....thing is, you probably need to establish if the faults are related (unless you examine that area and find obvious chaffing on the looms there to body ground)....*IF* the fuel gauge is still broken (full needle deflection), I'd be headed for the boot, remove fuel sender wire, key on and measure the voltage there ~ it should be roughly 10volts. If that's ok, check sender to ground resistance...if this is a dead short to ground (and there's fuel in it), then sender has failed or something funky has happened to wiring in the tank. edit: ahh...rereading the thread, this is R32....above fuel sender test still valid tho'
    • I just changed the timing belt on my RB25DET NEO and wanted to get some opinions. I’ve been super cautious, did a lot of research, and took my time. I’ve driven the car, and it runs fine. After warming it up, I revved it to 8000 RPM a few times—no issues, everything held up.   After the drive, I heard a noise that I think is either the clutch or possibly a tight accessory belt. It’s not constant, just comes and goes.   I took the timing cover off to double-check everything:   Belt is on properly, Tensioner is tight, Did the 90-degree twist test—belt isn’t too tight or too loose.     What still worries me is that I noticed the belt seems to sit a little toward the front edge of the gears, especially on the idler pulley. It even looks like it’s slightly coming off the edge there. Is that normal?   My old belt (5 years old, ~3,000 miles) also showed a bit of wear on that same edge, so maybe it’s just how it sits? I’m probably overthinking this, but since it’s my first time doing this on a NEO and the engine is forged, I really don’t want to mess anything up.   Also, I’m thinking of swapping to a clear front timing cover with the glass window. Would you recommend NITO or HPI? HPI looks reputable and their covers have 2.5mm thickness, but not sure if there’s a real difference between the two.   Any advice or reassurance would be much appreciated!
