benm - there is a video of a mines GTR going around the track driven by jap drivers going "holly shittt this is fast" "too fast"

the response on it is crazy... That car has a lightweight drivetrain...

ie light wheels, light flywheel, carbon propshaft etc.. anything in the drive train lightened to help increase response

i also remember sydneykid and someone else talking about the benifits of lightening certain parts of your drivetrain, and what benifit each has - its in here somewhere :P

by more "Race" I mean that when you change gears, the revs drop quicker, and whe you get on the gas, there isn't any surge from the engine which previously had to slow to match the road speed.

It's a bit hard to understand, but it does sound much cooler.

FURTHER REPORT

In wet weather, once the car breaks traction, the revs rise heaps faster, so you have to be a little bit more alert; but they also drop quicker, so removing your foot from the pedal stops the qheels spinning heaps quicker also.

I dont think you can see much of a difference if you could lighten up the auto flywheel. The auto flywheels arent like manuals since theyre just mounting points for the torque convertor and ring gear. The torque convertor by itself is very heavy and on top of that its filled with ALOT of fluid.

One problem with the flywheel is it is only around 8mm thick at the clutch face so it overheats very fast so be careful what you use your car for.

Do you know whether certain materials are better than others in this regard? i.e. Chrome-molly, Billet Steel etc?

A single billet flywheel is going to be very strong and not significantly effected by heat vs it's strength. A multi material flywheel like the one shown might have issues with different expansion rates but, the few race aluminium ones that I have seen never had a problem.

The chromemolly ogura 4.8kg is 400% stronger than the factory cast iron one.

      Strange issue RB25DET wont start

      By jtha7 · Posted

      Ps i found the below forum and it seems to be the same scenario Im dealing with. Going to check my ECU coolant temp wire tomorrow    From NICOclub forum: s1 RB25det flooding at start up Thu Apr 11, 2013 7:23 am I am completely lost on this. Car ran perfectly fine when I parked it at the end of the year. I took the engine out and painted the engine bay, and put a fuel cell with an inline walbro 255 instead of the in tank unit I had last year. After reinstalling everything, the engine floods when the fuel pump primes. if i pull the fuel pump fuse it'll start, and as soon as I put the fuse back in it starts running ridiculously rich. I checked the tps voltage, and its fine. Cleaned the maf as it had some dust from sitting on a shelf all winter, fuel pressure is correct while running, but wont fire until there is less than 5psi in the lines. The fuel lines are run correctly. I have found a few threads with the same problem but no actual explanation of what fixed it, the threads just ended. Any help would be appreciated.

I found the problem though. There was a break in one of the ecu coolant temp sensor wires. Once it was repaired it fired right up with no problems. I would have never thought a non working coolant temp sensor would have caused such an issue.

      Strange issue RB25DET wont start

      Hi sorry late reply I didnt get a chance to take any pics (my mechanics on the other side of the city) but the plugs were fouled from being too rich. I noticed the MAF wasn't genuine, so I replaced it with a genuine green label unit. I also swapped in a different ignitor, but the issue remains. I've narrowed it down a bit now: - If I unplug and reconnect the fuel lines and install fresh spark plugs, the car starts right up and runs perfectly. Took it around the block with no issues - As soon as I shut it off and try to restart, it won't start again - Fuel pressure while cranking is steady around 40 psi, injectors have good spray, return line is clear, and the FPR vacuum is working. It just seems like it's getting flooded after the first start I unplugged coolant sensors to see if its related to ECU flooding but that didnt make a difference. Im thinking its related to this because this issue only started happening after fixing coolant leaks and replacing the bottom part of the stock manifolds coolant pipe. My mechanic took off the inlet to get to get to do these repairs. My mechanics actually just an old mate who's retired now so ill be taking it to a different mechanic who i know has exp with RBs to see if they find anything. If you have any ideas please send em lll give it a try. Ive tried other things like swapping the injectors, fuel rail, different fuel pressure regs, different ignitor, spark plugs, comp test and MAF but the same issue persists.

      Freddy Plenum vs Genuine options RB25

      My return flow is custom and puts the return behind the reo, instead of at the bottom. All my core is in the air flow, rather than losing some of it up behind the reo. I realise that the core really acts more as a spiky heatsink than as a constant rate heat exchanger, and that therefore size is important.... but mine fits everything I needed and wanted without having to cut anything, and that's worth something too. And there won't be a hot patch of core up behind the reo after every hit, releasing heat back into the intake air.
