Even with cams they said. I have a highflow turbo and lots more power than that. I have my dump and front pipes HPC coated but they were like that from new so no idea if it works.

I think SK has it. I used to have a pretty much perfect tune til I messed with it. Later I got someone to touch it up. He removed quite a bit of fuel in some low load points. That seemed to introduce this jerk you guys are talking about. I was going to (one day ) tempoararily richen the whole map to test if it was simply the AFR but I see now it might just be the difference between tuning points.

I am using 480cc injectors on my R34 with GCG highflow turbo. Turbo I think is only a little below a GTRS. With cams at 270rwkw (Unigroup Dyno) I am very close to maxing them out.

I haven't heard of any CP's failing for reasons of bad manufacturing but I haven't heard of any Wisecos doing that either. Have you Pete? (Not attacking, just asking.) I used Wisecos because they have a longer skirt so I think they stay more square in the bore which should long term result in less bore wear. Also the skirts are teflon coated from factory so less friction. I think they recommend something like 5-6 thou piston to bore clearance (can't remember for sure though tbh). I used 2.5 and have had no issues.

But I'll just add that for 250rwkw and a highflow turbo you are probably best to upgrade the cams.

I'm overbooking 4 people as I know there will be some pull outs last minute so you can still enter as per usual.

The council wont let us go on there if it's mud. We will be assessing the situation on friday. If need be we will postpone the event by 2 weeks.

No cost for passengers but they need one of the licences, L2S or Wakefield.

Are you comparing a high flow GTST turbo to a high flow GTT turbo or a stock GTST turbo to a high flow GTT turbo?

I was told by a well known tuning shop in sydney that a highflow turbo wasn't capable of more than 220rwkw.

Ooh look at me! I can flame newbies. How cool am I?!! Yay for me! Die Newbie Die!!!!!

Well one example I was given was 30 hp for the $1200 cost of coating bearings and all other internal moving parts to reduce friction. I've seen people pay more for that kind of gain. In this case it was because the class of racing used restrictors and they already had cams etc etc.

Fair few but want more.

Inpribible?

I was thinking along these lines. What piston to bore clearances did you use on your GTR Leewah? For my 2c I told my engine builder my planned run in process (which I had got from someone else and involved about 5000 k's) and he told me load it up where possible, vary the revs as much as possible, increase the revs gradually over the k's and I should be redlining it occasionally by the time I got to about 500k's. He said if it's going to blow up he wants it to happen within 500 k's. I certainly noticed the tightness as first and it didn't fully free up until about 1000 k's. I have tight clearances though. 2.5 thou piston to bore.

Moved to FI. I thought the drag guys would be interested in this but I've heard that they and the rally guys are quite secretive about the coatings they use.

Nice gloves nancyboy.

Rain makes things very slippery. Give Louie from Xclusive Colours a call. He's the best and he's cheap if it turns out better to not claim on insance. 0413 581 099

I'm hoping they got out safe and don't realise people are looking for them.

They do actually have noise limits although they are generally not rigidly enforced during the day. Turn up at night with big noise and you'll hear about it though. Yes $ today = a spot.

700 tons of fuel mate. That's not a small spill.

Online entry form is temporarily down. Please wait til tomorrow for updates.

About 5 spots left.

I have been talking to Stuart at Pro Coat on the central coast as he is sponsoring the show n shine and he said 50% of his work is coating turbo exhaust housings and manifolds so we decided to put on a group buy. Haven't had much interest so far but I've been thinking about it a bit as well as talking to him about other coatings. He has done an evo where he coated pretty much everything in the engine, ie bearings, pistons, combustion chambers, manifolds, oil pump gear , etc etc. I think he said they got 30 more hp with no other mods which he put down to less friction among other things. Anyway, I find the whole thing pretty interesting and don't recall seeing much discussion on it here so I thought I'd post up and ask what coatings people on here use and if they've managed to prove their effectiveness or if it was too hard to measure properly? I know two06l has some bits done, I think the rear housing and manifold?? Stuart was telling me that he has this graphite coating I think that draws heat away so that is being used on the inlet side of things including intercoolers. I've got teflon coated piston skirts. Bit hard for me to tell how much use it is though. Anyone know their stuff here or have some good links? Cheers.

Hmm, those shims I pictured were in my R34 with both the viscous centreand the mechanical centre. That's not to say there aren't other shims in there somewhere that I don't know about.
