Hi all.

I want to go to wsid, but I want to break into high 12's....

At the moment Hybrid FMIC, filter, mongrel exhaust, locked diff, 4 puck clutch, fuel pump 040??, Dr Drift Ecu, r33 turbo,no interior bar two front seats. 255 rears on 17's. adj cam gears to go on (180rwkw?)

I'm curious if this will achieve a high 12, or do I have a little bit to go yet???

What are your experiences in breaking 13's???

Cheers.

My R32 when i had the RB20 in ran a few 12.9 @116mph on 225/45/17" street tyres.

It only made 188RWKW with a small hi-flow turbo, intercooler, 3" exhaust and ECU, so it CAN be done you just need another 15rwkw or so.

That MPH is MASSIVE for only 188rwkw!

Yeah, the MPH is a bit higher than my VL which had 200rwkw and ran 12.6@112MPH.

Ill try and get the timeslip up, my car was car# 600, i cant find the actual 12.9 with 116mph, but here is a 12.9 sec slip and one when i started pulling 116mph.

sky30, thats a brilliant result

the best i managed was 13.1 @ 108mph with 225/50/16 street tyres and standard suspension. That was on about my 8th run of the day.

i was making 207rwkw with a hks2530 and ~1.25bar

but sky30's time makes my efforts look dismal!

173rwkw = 13.3@106mph (2.3 60ft) on 205 tyres R33 gtst. 33 deg ambient.

Dyno numbers don't tell you everything. I recently thought of tracking the time over the x axis for rpm. This way you can track the accelleration times under load in each gear. This will directly translate to a relative 1/4 mile prediction as things like rotational mass greatly affect accelleration and can be shown using this measurement, without it you can't see the benifit. The physical weight of the car and areodynamics are then the only factors left to associate.

Next time you go to the dyno get your stop watch out and see how long it takes to make the power. Bolt in a lightweight flywheel or lighter rims, change the diff ratio and see just how big an influence these things can have.

      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.

      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.

      R33 persistent issues. P/steering and lag/misfire

      There is a really fun solution to this problem, buy a Haltech (or ECU of your choice) and put the MAF in the bin.  I'm assuming your going to want more power in future, so you'll need to get the ECU at some stage. I'd put the new MAF money towards the new ECU.

      Any idea where I can get genuine MAF apart from used ones? I can't find any only for GTRs and unfortunately that price is not in my budget 🤣 I might gap my plugs down and put my splitfires in, they were only in for a year or so before I started the rebuild
