danielson Posted May 20, 2006 Share Posted May 20, 2006 (edited) im guna get flamed for this.... bring it on i guess..... what are the chances of a 500hp r33 gtst, using stock box and diff, to run slicks and not break anything? im not talking a soft launch, im talking , front wheels reaching for the sky 8500rpm clutch ripping type of launch... i have a set of michellin slicks and mt front runners, and i really want to improve my launches, and ive notice alot of hipo skylines do a rev limitting launch... i know it isnt healthy to do this, but will this much force shear a standard drivetrain? any people had experience with this? any and any reccomended slicks??? PLEASE HELP!!! Edited May 20, 2006 by danielson Link to comment https://www.sau.com.au/forums/topic/118724-time-for-slicks/ Share on other sites More sharing options...
MR331307 Posted May 20, 2006 Share Posted May 20, 2006 go to www.wild1motorsport.com and view my skyline my advice is get a gtr diff cradle and good suspension such as HKS rev to 8000 and drop the clutch the clips on the site are with MT street tyres i have the slick pass which i ran 10.8 on my computer which is ready for uploadinng and will be uploaded this week Link to comment https://www.sau.com.au/forums/topic/118724-time-for-slicks/#findComment-2185600 Share on other sites More sharing options...

JCMarshall_Law Posted May 22, 2006 Share Posted May 22, 2006 500hp, slicks, preped drag strip? Rev Limit launch, standard driveline = something broken. That is my "expert opinion".

Sydneykid Posted May 23, 2006 Share Posted May 23, 2006 (edited) What car is this? Our white R33GTST project car, sort of a replacement for the R34GTT daily driver I had a couple of years ago. Bought it cheap a few months ago, needed rego and SOME work, it's getting there. So far it has a Power FC with Boost Control Kit, standard R32GTR intercooler, alloy 120 degree pipework, Bilstein and Whiteline suspension, GTRGeoff HICAS eliminator, Magic cat, Nismo FPR, GTR fuel pump and a quick and dirty road tune by me using the Tech Edge A/F ratio meter. Following the clutch failure at WSID, right now it is getting a new clutch, lightened flywheel and serviced gearbox (no synchro on 4th and 5th). Plus I had to drive it home clutchless (testing my dog box rpm matching skills). We just wanted to get a base time on the standard turbo, but too much traction from the MT ET’s for the unknown clutch. A GCG ball bearing high flow is ready to go on shortly with a Performance Metalcraft split dump, followed by a set of injectors and a pair of 256 Tomei Poncams. Looking for around 265 rwkw and a mid 11's 1/4 at around 125 mph. Before then it will get some new DBA slotted rotors, a set of Hawke pads and a timing belt change. Plenty to do, no time to do it in. cheers Edited May 23, 2006 by Sydneykid Link to comment https://www.sau.com.au/forums/topic/118724-time-for-slicks/#findComment-2194007 Share on other sites More sharing options...
lukits01 Posted May 23, 2006 Share Posted May 23, 2006 cool, thats fairly similar spec to my car actually you think a Auto gearbox with valvebody, shift kit, and transcooler would be fine if I used Mickey Thompson Street ET? considering stock torque converter is arround 2000rpm only and not 6000rpm dump the clutch launch ehehhe Link to comment https://www.sau.com.au/forums/topic/118724-time-for-slicks/#findComment-2195018 Share on other sites More sharing options...

For example I can get the Stagea up to 2,500 rpm on the standard turbo which gives 11psi at launch. This generates considerable heat, so make sure that you have a decent transmission cooler. If you can spin the wheels now, then decent tyres will help. I like the MT Street radials as I don’t have to change front tyres and the guys are down to low 10’s using them, so they obviously work OK.

Cheers Hey SK thanks for the advice, I have a oil temp gauge hooked up to my transmission cooler to monitor temps. But my engine is a RB30 with HKS2535 so it boost pretty early Plan to stall it on the line and launch as hard as I can with MT Street ET My street tyres are Bridgestones RE01 and its very easy to spin them on first gear Link to comment https://www.sau.com.au/forums/topic/118724-time-for-slicks/#findComment-2201016 Share on other sites More sharing options...
2rismo Posted May 25, 2006 Share Posted May 25, 2006 5500rpm launch on MT ET Street Radials. Clean sheared the CV Shaft in half. 6500rpm and the bearing cage explodes. Big. I only make 355hp @ the tyres (approx 410 engine hp).

bpd80 Posted June 29, 2006 Share Posted June 29, 2006 whats with this jimm berry clutch your talking about, who deals with them? are they really as good as you seem to think? I think Jim Berry is in Brisbane, Aaron at Wayne Park Automotive organised a clutch through him for me and he knows Jim quite well... Clutch is a single plate with about 2800 pounds clamp pressure std is about 1800. I hear people talking about 4000 pounds, but so far so good with 2800. have launched the car countless times and never a problem, just dial up about 6500 and let it out quiclky and all four light up on the std gtr 16's. 18's now fitted but yet to launch it with the increased traction.. nice smooth easy clutch to operate...

shanef Posted June 29, 2006 Share Posted June 29, 2006 whats with this jimm berry clutch your talking about, who deals with them? are they really as good as you seem to think? Jim Berry is the name of the owner/guy who makes custom clutches for all types of applications. He swears by a big single even for 800hp+ drag cars (subzero soarer, millenium motorsport supra) he hates twin plates with a passion, so dont even ask him what he thinks of them also he is quite 'cheap', bout half of what youd pay for a jap twin plate Link to comment https://www.sau.com.au/forums/topic/118724-time-for-slicks/#findComment-2296470 Share on other sites More sharing options...

It's the NOS making the axles brittle. cheers SKDon't forget the Bass Junky Air Deflector I wouldn't know, I don't have one cheers Edited June 30, 2006 by Sydneykid Link to comment https://www.sau.com.au/forums/topic/118724-time-for-slicks/#findComment-2297790 Share on other sites More sharing options...
