Re: FFG 549D Rally car

Not there yet with any costs, lots of testing to be done after i have identified the parts and bought them, it will probably be like most of the things i have developed for the rally car. Most people will say it is too expensive and high performance for their road car but the first rule of motorspor...

Hi Oli. Yes i would lubricate the threads on head studs if you are using ARP studs and nuts they will come with a good lubricant. ARP lubricant can be bought on line there are others molybedium (not sure of the correct spelling) is used in most proper thread lubricants, on the ARP site there is good...

Re: A Californian drying out in South Africa

Andy that is not how a spring washer locks. It is the spring trying to expand that applies a tension load on the stud/bolt. It is the tension or stretch of the bolt/stud that keeps things tight. Torque is the turning motion of the nut/bolt on the threads that is calculated to put set level of tensio...

The big difference with the mintex Halo compound and the old VG95 is that once the Halo is bedded in correctly that is it, you should have better than road car brakes when cold and if you drive at rally speeds on the road (many think they can but actually cannot) they will not fade.

seriously do not try this with your engine an unloaded rev up over half max rpm will be ok every now and then but buzzing to the max will not be good for a standard engine.

Re: A Californian drying out in South Africa

You still do not know what is letting the pressure escape. Could be worn exhaust valve seats, could be worn inlet valve seats, could be valve clearances, could be piston rings, could be oval bores, could be tapered bores, could be all of them.

To carry out a leak down test and gain results that relate to how the car is running yes it is best to carry out at normal running temp. This can show up a tight tappet gap that prevents a valve fully seating when valve and head etc are hot an have expanded. It also ensures the piston rings and pist...
