Superlap Timeattack Is Ago!

[gtr jason]

sounds like you forgot the rings when you where building and tuning the car in your drive way ha

[hrd-hr30]

Marks laps in the video looked very clean indeed!... I would say that comparing the S2000 v the GTR lap, the GTR was the one that had less drama about it... throttle application was smooth, and tended to be only 1 go at it...

what was the lap time difference between the 32 v 35 and say the S2000???

JB's driving style certainly is exciting to watch!!! butI'm not so sure on it bringing the fastest lap time.

there's a common misconception going around that to be fast you have to be smooth. This really only applies to cars with lots of aerodymanic grip. If you are running around perfectly smooth in a prod car even on semi slicks, you are loosing a bit of time. You only need to look back to any production based racing (Group A, Group C, or current Improved Production etc) and you will always see that the fast guys are running right on the edge like Boz in the S2000. Particularly when you are going for the fastest possible single lap from the car - like in qualy or in this case at Superlap. Its only when it gets 'too' sideways that its slower than being smooth.

so who owns this gtr? and was this the one with dry sump?

[phunky_monkey]

Not sure if that GT-R has one too, but this 32 ran a dry sump

[Beer Baron]

no idea on the silver one, but the grey one is matt's. top bloke and he did very well considering it was only his second time at oran park too. it runs all the good gear. dry sump, PPG dog box etc etc. very nice car. with the scavange from the head it doesn't breathe at all. i mean nothing. it doesn't have any pipes fitted to the cam covers and not a drop to be seen anywhere in the engine bay. for quick GTRs dry sump is the way to go it seems.

[Beer Baron]

actually, now I remember. the silver one was dry sump too. and it had a weird screen made of particle board, and all these ducts and fans and vents in the boot. some of it looked a bit nautical! should slap that into johns car.

hmm I'm no mechanic but do healthy engines breathe 1l/lap? Is it due for new rings soon or does it just have big clearances?

Didn't you read the post you deleted?

This is a brand new mega-buck engine built by another workshop located in Sydney. I wanted to build it but Dave believed he could get a good product as the workshop in question had employed a good engine builder. The car had a built engine of unknown origin in it when it cried 'enough' on their dyno. Dave decided it best to leave it in Sydney and let them take care of it. Clearances are unknown but since the thing was running so rich on run-in it may have had a ring sealing-bedding in issue from the get go. It has always blown oil smoke since the day he picked it up which is something that has always concerned me. Dave now realises his decision to leave the car in Sydney was a mistake that has cost him a lot of time and money. He now wants me to pull it down and inspect it.

Not throwing mud here...just stating facts. If this post breaks forum rules please delete.

gtrjason what style of breather system do you run, any help is always welcome.

You GTR guys make me laugh. Dry Sumps, breather systems nail ppolish removers. Sheesh, i read everywhere they are king of the track. Just man up, throw bigger turbo on it, more boost and use a Gatorade bottle (i am a proud Aussie so i use Powerade) as a catch can. If the thing breathes then throw the 26 to the shitter and put a 20 in it. Nissan build a perfectly good, strong reliable track engine in the 20

LOL.... the Minister is alive and well

Hey guys Paul isnt stirring crap he has just stated the the facts as to what happened over ther superlap weekend. My car did have a lot of blowby after 2 laps we didnt even get a good lap in really as tyres wearnt even warm but we still managed a 1.18 considering the dramas we had with the catch can filling up so quick. The engine was built by a very respected engine builder he is very carefull with the way he builds his engines checks everything twice plus is clean with the way he does things. Paul has been a great help to me in the past as well as the present he has just been looking out for me & the GTR as he does no hes shit Its his second nature the GTR. One other thing the car never has blowby on the street or on the dyno so god only knows. So me paul wouldnt mind stripping it down to see if everything is ok. Last tuesday would of had at least a 1ltr of oil in the intercooler & some in plenum chamber its all clean now thou & guess what no blowby all week.

[Swiper the Fox]

How is Powerade more Aussie than Gatorade?

yeah that's fair enough. plenty of GTR will experience some blow by under track conditions as it's a long way from street use/drag use/dyno. it probably just needs some smart catch can work and maybe an external oil return if it doesn't have one. 1:18 is fairly moving so it's doing pretty well for a road car.

[BezerkR32]

Paul,as you didnt build it i know its a hard question to answer but could it be something stupid like the restricters werent fitted and its pumping the valve covers up? its the only thing i can think of other than an internal problem causing massive crankcase pressure which can only be a ring issue. incorrect ring gap or broken ring....but at the end of the day, shouldnt this highly experienced engine builder be looking at rectifying the issue?

LOl, because Coca COla do a wonderful job of pasting Australian Institute of Sport crap all over the bottles so most people think drinking it is supporting our athletes etc Yeh, its not !
