Progress Update: How Is BCL's Car Going?

[geea]

Brian, I know with my car at it's current power levels that traction and tyres are a big concern. What tyres are you planning on using?

Still undecided yet Craig, although I have noted everyones comments.

Motor issues are still being finalised, stronger CV's to be built, then rubber determined, then review future options. As I said in earlier posts I can (and most certainly will) turn power levels down on the street until I'm comfortable that I can cope, and that I have rubber to handle it.

Great work Brian, good to see someone doing this to a Falcon XR6T (stick with it rather than the Territory - much cooler).

If you are after more reliability in the drivetrain, you are probably best to go the direction of the diff that the V8 Supercar guys have - a solid axle. CVs are always going to cause an issue, even if you get them to hold together. I have a Cobra replica with race 454 cu in Chev (around 700hp), that has a 9 inch center - converted to independent rear end, and whilst the CVs don't break - they wear out after a very short time (get slop in them). The car used to twist axles (much bigger than the XR6 ones) when it had a locked diff. Also for diff and gearbox reliability - fit external pumps and coolers, heat is the killer once this much power is pushing through them.

Also to aid traction, a very stiff roll cage does wonders, as it stops the whole car twisting and lifting a rear wheel.

Is your car on standard engine mounts? My Car has solid mounted engine and gearbox, which helps stiffen the whole car, and removes some of the twist in everything - though in a saloon it may cause too many rattles and vibrations.

As far as 400kph goes - I wouldnt. I have done 310 in the Cobra - and it started getting a bit light (ie the car was starting to lift). I then made a flat bottom for the car, closed in the passengers side (my car has an aero screen rather than a full screen), and then we lost access to the airbase we used to race at (big long straights).

Everytime I drive the Cobra you get a real addrenalin kick, and get out of the car with a bit of a shake. Your car I will imagine will be even hairier with more power, and the way that a Turbo delivers it.

Cheers

Any truth to the rumour Brian from a couple of months back that she spun a bearing on the engine dyno & had major damage on tear down??

There I finally said it

No truth whatsoever.

As I said in an earlier post, some internal components have been replaced with stronger components, (and I won't divulge what), after an ongoing assessment of the motor.

As this is really the first major build project of an XR6T, and the only XR6T running just on 800rwhp (to my knowledge), we do expect issues to arise, plus I'm not pushing Simon to give me the car back quickly.

any updates brian, still at the same power level?

[bcl]

I spoke to Simon on Monday, and he'll be back on the car later this week.

He ordered about 20 units of a part that has been breaking on engines, and tested that on his ute last week, that will go on my car. He also finished testing another 6-speed with special cams and Motec that was putting out around 500rwkw, and using some new components from R&D that will go onto my car. Unfortunately that other car destroyed an upgraded clutch in just 1 pass at Calder the week before last (the same guy that owns the Nizpro twin turbo Ferrari... ref http://forums.nizpro.com.au/phpbb/viewtopi...ghlight=ferrari ). Upgraded CV's is a separate project, don't know when they'll be available. I sent him an oil pressure gauge to replace the oil temp.

The power will be kept at the 600rwkw level (maybe just a tad higher with upgraded turbo compressor), but with a bit more stability around the 7000-7500 rpm level.

So not much to report.

I'm starting to get a bit more eager to finish this project, as I'm ready for my next Sti upgrade, to take it to 300awkw, using a new kit that's been developed in the US for the 2.5L motor.

Thanks Adam, rubber will be another issue altogether, and I had received quite a few good suggestions so far, from yourself and others.

I don't know if they used the NOS on that car, as it was just being basically tested... maybe the owner was over-enthusiastic.

Someone was telling me the other day there is a 20" tyre that gribs really well dont know how true it is with no sidewall but they were claiming they stick like the MT streets

Myself and craig are considering going to a 17" rim something like a touring car so we can run good tyres all the time
