In-car video showing the 34 boosting hard on full boost or its not true? Nah man but Im sure we would all love to see

When I get the boost controller sorted and I can

Find an appropriate "private road" or track :yes:

At the moment I haven't kept the throttle down long enough to enjoy, once it starts getting loose in 3rd I back off... Need better rubber for sure

Yep We're jealous of full boost at 6000rpm with a gtx35

Back again, 372kW @ 1.75bar (1.8bar spiked a little)... motor has not popped and even went to a track day on the 30th of May. Motor did push some coolant, I believe the OEM head gasket isn't too happy

ku36 tyres arent that bad, what width are they on the rear?

265.... Either KU36, RS-Rs or Achillies 123s.... Just cheapies as they won't last long anyway :D

don't waste your $$$ on KU36

they are pretty decent for what they are but kuhmo have increased their price in the last 12 months and you can get Nittio NT05's or Federal RSR for less.

imho for a street car go with the Nitto's or if you can stretch the wallet grab some advan AD08's

I usually run the NT05's all round and with my suspension setup they give me effortless traction in 2nd right up to about 310rwkw (e85 on 16psi) - beyond that i need to think about what i'm doing

+1 for AD08's, great tyre. Once they get the heat into them they are awesome

I'm using 265/35R18 RS-R's on the back and they only just manage to grip 2nd with 280rwkw and a toight like a toiga diff (shimmed).

Have you tried them out at Barbs dude? I found my KU36's are ok on the street, but they really come alive when you get some heat into them on the track.

Thanks mate... Will hopefully get it sorted before Texi...

360kw was the highest run... It was run @ 357kw on the final tune for safety... The reason for the different power figures is the 3 boost levels and also the % of ethanol.... My power ranges from 311kw to 357kw depending in boost and E content :)

Hope that makes sense?

Do you have a dyno sheet, or did I miss it ?

Don't KU36s last longer than RSR though? I know RSR is a more grippy tyre but they really don't last.

The KU36's have a treadwear of 180, the RSR's are 140. So not a huge difference. I know my KU36's lasted about 1 track day and maybe 8000km's, so they don't last either.

What type of driving would that be, around a track ?

would they last longer with normal street driving and occasional short blasts?

I drove it hard at the track and spun out on a couple of occasions, so I have no doubt that took off a fair chunk of life. But I only got in 10, maybe 12 laps. On the street I drive pretty sedately with the odd 1st, 2nd, 3rd bursts. So they don't last very long, but no doubt without the track abuse they would last longer.

I think you'll find that if you don't destroy the compound on the tyres by tracking them hard, doing skids, etc. etc. then they would last a fair bit longer. But I'd be surprised if you got more than 15-20k km's out of them.

I have KU 36 on the front, but they sat for 2 years so maybe hard now? They gripped real well compared to other tyres.... Was happy with them. I have some shit sumitomo or something on the rear hence why I have no grip....

Rolls - sorry mate, I have 4 dyno sheets, just haven't had time to scan them.... I have 98 sheet, gate pressure E85 vs 98, low boost E85 vs 98 and then just high boost on E85.... Will get them

In here and in the RB 25 thread soon.... Sorry over been slack :)

      R32 GTR clutch master cylinder adapters

      We just disconnected the vacuum line if I remember correctly, booster is still there. Is there a rebuild solution for the booster or a different adapter that will work for GTR chassis?

      Yeah 4wd (boosted) has a recess in the firewall for the booster, and 2wd is flat - the example in the link shows the flat surface. When you deleted the booster, did you just attach the factory slave cylinder directly to the recess in the firewall with no adaption?

      Yes, but no. You need to keep the mating surfaces bare (ie the flat faces where the caliper and upright pads touch the dogbone) and also the internal threads will remain bare (unless there are no internal threads - do they use nuts on all the bolts?). So you can slow down obvious external corrosion, but not all of it. Anodising would be required to provide decent protection to the alloy, but I'm not actually sure if you should anodise something that is all about the strength. Anodising does reduce strength significantly. Like, up to 50% on some alloys for high thickness coating.

      Thanks   does painting on aluminium work or stop them from corroding?

      'Sgot nothing to do with them being Japanese. The climate in the north of Japan has similarities to the UK - the cars are made in the knowledge that they have snow and salt, and they rot there. Cars made in the US rot like buggery in the US. British cars have always rotted regardless of the weather. They will rot indoors in a climate controlled bubble! The brackets are not unsafe yet, but they will get that way. They may well corrode where the bolt threads are in contact and the bolts could just jump out without warning.
