When you have a comparison please share. I've finally got the tts fwd guys running quite well now after many hours of tyre trueing. Not as quick as the small wheel mini on my track but good fun nonetheless.

Will do mate....

What have you done to your TTS? I was talking to a chap in Europe about them and he suggested putting on a 13t pinion. He also put small rubber rings on the suspension parts to firm it up a bit.

I haven't tried either yet - lately we have been running the big BRM cars.

cheers

Just a blueprinting really. I removed a chassis burr which was fouling on the body, did the cigarette paper trick to space the gears after grinding the gears in with lapping paste. At first one of the cars lept sideways under acceleration out of corners, this was traced to the rear tyres not being spot on true. After the rears went back on the tyre truer lap times improved greatly.

At this point I'm happy with it, however as I'm not club racing these days there's most likely a few tenths left to find.

The big cars are a blast on my new layout (100mm lane spacing, so much better for these), a bit terrifying though. We like to have a few drinks and race, the trans am battle is a bit messy after a few, just ask the scenery...

Yes we ran them the other weekend on a BRM day - they were great fun. MJK on some but mainly stock rubber. We found the stock rubber hooked up nicely with a bit of NSR oil.

We ran them at 9v - I think 9 or 10v is all they really need.

My track is ordinarily at no more than 10.5v, it's fast and flowing, is not modular and only has three braid joins so conductivity and momentum are no issue.

I've found wiping rubber tyres with Turps is also effective, particularly at the end of trueing. For me not as much benefit as the nsr oil but quicker results without lingering goop. I haven't tried oil on the 'big' cars, I'll hit one of my Camaro's with nsr oil and see what happens, i'm guessing i'll go through yet another fence trying to stop it, shortly after smashing a class lap record.

Are you changing gear ratios on the trans am cars? If so where are you going with them? Between the two of us we have 5 and all have all the power but none of the braking, kind of like a real v8...

Will try the turps especially after truing, they are a challenge to true up.

We haven't change anything other than the tyres so far. My Toyota with stock - treated tyres was the quickest Grp C - with the Trans Am I bought the new Mustang and it went really well with very little work on the tyres. I wiped a bit of oil on them and that is about it.

I have several 917k they hook up nicely. With stock tyres though one has some sort of urethane - not sure what they are though.

I had the toyota and a porsche 962kh, once i stopped club racing they were sold as my old track had 90mm spacings. The Toyota had many victories at Ged's, although back then they were all inline and crown gears were terribly fragile which resulted in fields dropping by over 50% by the end of race night.

I'm still waiting for brm to release new liveries of the 917 and 512, i wasn't in the 1/24 market last time around and the 2nd hand market is too inflated given i'll be slowly destroying them on track.
