Currently using MT ET radials - good for preliminary runs but will require slicks.

What i need to know is in the heat treatments GTR they are running the same wall and tyre diameter front and rear but the widths differ. The rears are substantially wider than the front.

They look like Dunlop may be Hoosier . Any one know what make and specs of tyre will allow me to do this and also what rims would be suited?

As i have mentioned i currently have standard GTR32 rims withy MT Et radials but need info to run slicks .

Also, if you are using an adjustable torque split controller (like the HKS or even hydraulic one) wouldn't that negate the need for same diameter tyres? Are you also allowing for tyre growth on the rears?

Nah - centrifugal force - both front and rear - i would say same tyre or similar growth , may be minimally larger at the rear when spinning but that doesnt count.

looking into the slick side of things - not that easy to find out info.

My rims are mint GTR and the MT are new and haven't been on car yet . I would like to work with you on this but i firstly have to find out the price and availability of the Bogarts and Goodyears - any idea where to buy these from?

www.bogartracingwheels.com :P

what about weld wheels?

MT ET drag wheels are about 5.5 kg each in 15 x 8", but the Bogarts are the lightest I know of (4kg each) and are about $400+ each wheel

Dave,

You can get weld racing rims from the states for just over $1000 delivered for 15x8's and are available in a heap of offsets. I reckon some M/T 15x26x8.5's would be a good starting point and are readily available especially toward the end of the season as they have sales.

I have a question about the legalities of running a slick on an awd car as I know last year it wasnt allowed under andra rules but they made exceptions for certain cars. Can anyone tell me if that has been changed in this years andra rule book?

Have just had a look at the Weld site Smiley - the $1000 delivered from the states is not so bad realy? we will have to have a good look at the offsets particularly on the front as i want to have her as low as possible but now with the ET's that i have -if i go any lower my uper arm will rub. Once she is back from the paint shop i will have to address this on a closer level.

May be i should just stick to what i have at this stage and in the interim check the ANDRA status?

I have a set of 5 stud 15x8 weld pro stars here with a 4.5" back space with some 15x26x8.5 M/T slicks you can try on to see whats going to fit.

That sounds good Smiley - didnt know you had those? Oh well that turned out well , catch up with you over the week end.

The tyre and rim thing is resolved -thanks for all your input.

Fortunately scored - Advan rims and 10'" slicks - tyres not suitable for use but good for set up. A simple die grind over the calipers and on they went. These were off the Tomei Drag car that Hi octane had - i consider my self lucky and thanks to Mark Jacobson from Godzila racing.

Any one know where to attain extra long wheel studs and open light wieght nuts??post-10298-1212224284_thumb.jpgpost-10298-1212224052_thumb.jpg

      The oil pressure sensor for logging, does it happen to be the one that was slowly breaking out of the oil block? If it is,I would be ignoring your logs. You had a leak at the sensor which would mean it can't read accurately. It's a small hole at the sensor, and you had a small hole just before it, meaning you could have lost significant pressure reading.   As for brakes, if it's just fluid getting old, you won't necessarily end up with air sitting in the line. Bleed a shit tonne of fluid through so you effectively replace it and go again. Oh and, pay close attention to the pressure gauge while on track!

      I don't know it is due to that. It could just be due to load on track being more than a dyno. But it would be nice to rule it out. We're talking a fraction of a second of pulling ~1 degree of timing. So it's not a lot, but I'd rather it be 0... Thicker oil isn't really a "bandaid" if it's oil that is going to run at 125C, is it? It will be thicker at 100 and thus at 125, where the 40 weight may not be as thick as one may like for that use. I already have a big pump that has been ported. They (They in this instance being the guy that built my heads) port them so they flow more at lower RPM but have a bypass spring that I believe is ~70psi. I have seen 70psi of oil pressure up top in the past, before I knew I had this leak. I have a 25 row oil cooler that takes up all the space in the driver side guard. It is interesting that GM themselves recommend 0-30 oil for their Vette applications. Unless you take it to the track where the official word is to put 20-50w oil in there, then take that back out after your track day is done and return to 0-30.

      Nice, looks great. Nice work getting the factory parts also. Never know when you'll need them.

      I take it that the knock retard is from bearings tapping a little tune? Thicker oil is a fragile bandaid. You need a much bigger oil cooler and probably the bigger pump being discussed.
