And some more pics

Oh man, that looks like so much fun.  A few questions if you don't mind.....

Who did the roll cage?
How does the handbrake work exactly?
What do those tyres cost?
Where do you get them?

Apologies if you've addressed these questions somewhere in the previous 10 pages.

Yep, best fun you can have sitting down, and this car should do the business quite well. If i can do half of what Greg Carr achieved, i'll die a happy man.

Rai Curry from Fabraications in Braeside did the cage. I am super happy with it.

Handbrake is plumbed inline to the rear discs. Push the handle and it closes off the line to the master cylinder and pressurises the rear calipers only. You gotta agree you can't lock up the rears with the half arsed mechanical thing. With this jigger you can lock up on bitumen at 160 k's if you want to.

Those tyres cost around $250 new. these are all second hand ones. paid $300 for 6.
All competition tyre joints have them. Traction tyres for yokahama, Stuckeys for bridgestone. etc
I have yokahamas ao35 195/65/15 30's on the front. these have been hand cut by Pedders rally team years ago. i came by them in a shed clean out.
I have silverstones on the rear. never used them b4, hear they might not be so good? I'll tell you how they work on monday.

You only need 5 mins in one of these cars to get hooked

What a weapon! Had a great weekend. Given the conditions ( torrential rain and hail) The GTV6 ran faultlessly. 4th outright in it's shakedown event is a fantastic result. And the autocross on the sunday was the best fun. 1.2 k's of sand track, kept it on the rev limiter in 2nd gear for most of it. Unfortunately dislodged 1 witches hat, which cost me 5 seconds. Took me from about 8th outright to 15th outright.

Congrats Greg - glad to hear all went so well! 

How do you deal with cleaning all the sand/mud from underneath - high pressure cleaner?

[dehne]

well done do you know what happened to matt

Martin, Thanks for the positive comments. Don't you wish you still owned it?
Drove it down to Pakenham Monday morning, ran thru every puddle on the way. poured a pocket full of gold coins into the BP car wash and left a lot lighter and much cleaner. The BP is good as the pressure washer there has a rubber section in the wand that can be bent around under the guards etc. Found a few rally guys to have a coffee with, then drove home the long way to dry it off b4 i hit the gravel rd to my place. I will jack it up and remove all the wheels and get rid of any lingering mud. Important to get it all off, as it stays wet for a long time, and we all know what happens to Alfas if they are kept damp!

well done do you know what happened to matt

Thanks Dehne, read about Mats adventures in this thread.

nope, happy to stick to the nord engine - besides need a 30+ year old car for historic plates here..

are you happy with ride height as is? you mentioned earlier to drop the front perhaps? I'm about to fit gtv6 bars to the alfetta gtv and I'm unsure how high to go - for motorkhana/khana cross/rally sprints purposes.

my rear ride height now with Alfa 75 3.0 springs is 345mm from hub centre to guard edge, and will go to 355 with the bottom rubber seat installed, front is 390 -  perhaps still too low..

[redalfaracing]

I did drop the front about 20mm from initial assembly. i put the pedders subaru outback springs in the rear and made an educated guess about the front. I think where it is now is just about perfect for gravel. I think the Bilsteins are working so well that the car doesn't dip too much in the rough stuff. I did get one small dent in the left hand down tube, but they are sloppily made. average quality mass produced items. when the 24 valve goes in i will custom make some headers that stay high and out of harms way.

Measured my GTV6  370mm center of axle to arch on rear, 400 on front. with 65 profile tyres gives oodles of ground clearance and i don't feel the handling is compromised for what i use it for.

Below are some pictures of the iside of the rims i used on the trial. This is why it is a waste of time balancing rally wheels. On the last transport back to rally HQ at 100k's on the bitumen it felt like it had square wheels. Might have to put some wheel scrapers on the rear.

[116gtv]

talking about wheels, Greg, whats your opinion/experience regarding running aftermarket wheels that dont sit flush on the hub centre due to a larger diameter opening,  which means all the load is taken up by the studs -did your alfetta always run factory rims?

also wanted to ask if you kept the factory brake bias valve pls?

and thanks for posting the measurements - appreciate the feed back!

[redalfaracing]

Martin, I really wouldn't use wheels with wrong centre holes for any sort of competition. nothing wrong with aftermarket wheels but they must fit! Adapters could be made i guess, but it's easier to use the correct wheel in the first place. I use Alfa 90 rims, which are speedlines 6 inch x 15, 5 stud 45 offset. I think they are fairly good although i have broken a couple over the years.

The factory bias valve is non adjustable. On the Alfetta sedan i replaced it with an adjustable one mounted in the cab. This worked ok but the GTV6 has a pedal box with a bias adjuster which is much better. took me a couple of weeks to build it, but it was worth the effort. pic below.
The Alfetta sedan had a  master cylinder out of a daihatsu L60v in it. The L60V is a light weight 3 cylinder buzz box that has a see-saw master cylinder mounted under the dash board ( no booster) Grafted that in and while i was at it i see-sawed the clutch cylinder too so there are no brake components under the bonnet except for the reservoirs. Took 15 kg off and put 2.5kg back. pedal was a bit heavy but it worked a treat. i can take some pics if you really want.

hi greg wondering if you could help me with some info. im going to make my white 90 an motorkana/autocross car and wondering if you have a few tips to make it better. im not looking at puting a cage in yet but when i do i need to get 2 done one for each race car

[redalfaracing]

Sure Dehne, First and foremost, remember the number one rule... light is fast. If you work on getting it light, it also makes it faster, stop better and turn better. Completly strip the interior, including the bitumen on the floor ( I know it's a pain, but it weighs over 20 kg) Get rid of the doors side intrusion. Not needed in a motorkhana or a speed event. Electric windows, piff them. Door trims, 1mm aluminium sheet. Rear window and side windows can be perspex. Fit 1 race seat and a harness.

Now that it's light on the inside, gotta get it to turn. Get rid of the rear brake presure regulator. just get a brake joining coupling off one of your wrecks and join the 2 pipes together. You need to have some way of adjusting the bias. you can fit an adjustable valve in the cabin within easy reach or get a pedalbox. 1st option works ok for speed events and is cheaper. Hydraulic handbrake is real handy for motorkhanas. Not in the hunt if you don't have one in a rear wheel drive. need brake pads that wont fade. Race Brakes RB74 are brilliant. If you are on gravel, remove the rear sway bar. Way too taily with it. standard height is ok. no need to make it higher and i wouldn't lower it. been on some autocross tracks that cut up at the end of the day. Bagshot and boisdale particularly. If you want to, take 3rd, 4th and 5th out of the gearbox. wont need them, save weight and syncros will last longer. really need a lsd or weld the diff as a last option.

now you have a car that is capable of winning class, if the driver is up to it.

I am entering a khanacross at Pakenham tomorrow. Wish me skill.

so the same as i did to the track car

. Get rid of the rear brake presure regulator. just get a brake joining coupling off one of your wrecks and join the 2 pipes together.

im guessing this is the bit beside the master cylinder

You need to have some way of adjusting the bias. you can fit an adjustable valve in the cabin within easy reach or get a pedalbox.
how do i do this will use first option

Hydraulic handbrake is real handy for motorkhanas.
how much are they i going to try and get second hand one from pedder arc team if im lucky.

need a lsd or weld the diff as a last option.
how hard is it to weld or should i just wait till i get a lsd but then i would prefer that in the track car first

now you have a car that is capable of winning class, if the driver is up to it.
prob not but will have a freakin fun time trying

[Mat Francis]

Whilst an LSD is great on the track, i would argue that if you are going to use both cars sort of equally, stick one in the gravel car first. 120HP on the track might get an inside wheel spinning out of corners, but not having one on gravel is going to slow you down a lot more.
