Can I Do Better?

Hi guys

Took the car down to the Motorplex to see how she'd run. It's an R32 GTS4 with an RB26 transplant and a plain bearing GT35 running 18psi. The car makes 408rwhp @ 7,250rpm

I probably should have checked the graph before I left as we were changing gears anywhere between 8,000 and 8,500rpm. So anyway, the best run was:

Elapsed Time: 11.995s

Terminal Speed: 118.11mph (190.07kph)

60' : 1.953s

330': 5.165s

660': 7.804s

660'speed: 151.57kph

1000': 10.078s

I did have previous 60' times of 1.7 so I guess I should have been able to shave a bit off that run above. It was still wheelspinning and torque steering a lot though.

So yeah, basically what I'm wondering is can I expect any better out of the car or is that about it?

Cheers!

I would have thought that with 408 rwhp (305 rwkw) it would have run with a TS around 125 mph. A TS of 118 mph seems to me to be indicating a power more like 270 rwkw than 305 rwkw.

Or am I being too optimistic?

:D cheers :D

Nope, that sounds about right to me, SK. Not too optimistic at all.

My prediction of 11.40 is based on the type of car and the mph it has actually run rather than the claimed power figure.

I brought the time slip and dyno chart to work today so that I can scan and post. Unfortunately I can only scan into a pdf format so by the time I've cut and paste etc it's in black and white. Once I get a bit of time later after the morning madness period I'll try and post them up.

Once you see the dyno chart then perhaps you could tell me if I am right or wrong in suggesting that the car could be quicker if changed at 7,000 - 7,250rpm rather than 8 or 8.2k like we were experimenting with

But yeah car was run in full street trim

      3D printing fun

      By Sean'O · Posted

      Howdy friends, So another weird one today, I was looking into replacing some broken clips holding the front grille for the R32 GTR (part number 01553-03831), and noticed the brackets which are supposed to hold the grille in place were also missing 😑. I do recall seeing this issue many years ago, but didn't fix it at the time. A quick look on eBay and I was able to find the genuine brackets, along with all the screws which suited the headlights (part numbers 26042-08U05,26092-08U05). Happy days!....  Once they arrived however there was an extra nut in the packaging which implied that there should also be a bolt or a stud, and sure enough, after a bit of searching I found this thread from 2013, and @Ants clearly shows a stud should be present. Reading around a bit more, it's possible the headlights on my car are the "povo pack" headlights as mentioned by @funkymonkey in this thread way back in 2008. This could explain why the studs are missing on my set of headlights. Looking at the headlight diagram I wasn't able to see a suitable part number for the stud itself. The headlight did indeed have a recess that looked like it would accept a stud, but interestingly no thread or anything obvious how the stud would be affixed to the headlight, I suspect it may have been glued in, press fit, or melted into the plastic at the factory. Another member may be able to clarify if they happen to have a genuine set of N1 headlamps. The only thing we have to work with within the recess is a keyway which likely is there to prevent the stud from rotating within the recess. In any case, back to 3D printing, I put together a model which acts like a pug with a friction fit inside this recess, making use of the keyway so it doesn't rotate while tightening a bolt. Printing in TPU will allow it to slightly swell making a nice snug fit without cracking the part. I've designed the adaptor it to accept an 20 mm M6 bolt (stainless with a cap head in my case), as opposed to the standard M5 stud and I made use of the standard galvanised split washer that came with the genuine brackets from Nissan. Once the bolt and screws were all in place, giving the bracket a gentle shake gave the classic "shaking the car" feeling, very solid, which gives me confidence this is going to be able to hold on much better than the janky solution which seems to have been here for the past decade or so. Overall I'm really pleased with how this turned out and maybe there are more people out there running these headlights without a centre stud at all!

      R32 GTS (RB20DE) clogged cat

      By GabsReDeal · Posted

      Hey everyone, This is my first post apart of the introduction. I tried searching a bit on the forum but couldn't really get a straight answer. I got the car to my mechanic as I felt it being weak. It seems that it was missing on two cylinders due to the injectors. I had all my injectors clean and the car runs much better. The mechanic also confirmed my suspicions that the cat is clogged and needs to be tackled asap. The cat rattles a bit and the hot exhaust warning frequently lights up when driving after getting the injectors clean. In my introduction I was asked about what modification I might be interested in and mentioned a cat delete. From what I was told, this is not really beneficial on the RB20DE and there are more cons than pros.  Could perhaps anyone give some suggestions on what the best course of action would be since the current cat is toast and needs to be removed/replaced anyway? I can also sometimes smell a strong smell of fuel, but I'm not sure if this is related.

      When I was replacing my pump due to being stranded in the wrong state, I went with the Deatschwerks 320lph kit. It is a direct plug in to the stock wires, harness, everything. It comes with a plug... but you can plug the OEM plug directly into this thing. https://justjap.com/products/deatschwerks-dw300-fuel-pump-nissan-s13-silvia-r32-r33-r34-skyline-c34-stagea?currency=AUD Downside: Won't actually flow that much on boost if you want to push it on E85, but it's comparable to the 040/255 etc. Little more actually.
