Re: The Orange Cab -MD's New Racer

Oh yeah, I should have asked before....................

Do you notice any changes in the car's balance now that you've added the supercharger and the intercooler?

Re: The Orange Cab -MD's New Racer

That's a sweet set up MD! :D :D :D

And the Cab looks even better with the white wheels.

But we all know that's a nice new Sprintex twin screw hiding under there. :wink:

Re: driveshaft conversion

After a bit more Goggling it's pretty obvious that an RTV silicone is completely unsuitable. It kinda, sorta doesn't stick to much other than itself............... :oops: The way I was thinking about it, each coupling would have 2 interlacing steel structures that provide the majority of the strengt...

Re: driveshaft conversion

Silly question time........................ :wall: While I love Kevin's approach to the tailshaft saga, what is stopping someone from making their own rubber couplings of a more durable design and perhaps with some internal Kevlar reinforcement? The big problem that I see is the actual rubber itself...

Re: Turbo Alfetta Race Car

There's nome nice work there! A couple of curiosities tho. Like the fact that 105 uprights are used, with 'upside down' lover ball joints (spherical rod ends), but no apparent bump steer correction. Also, the steering arms are standard (LONG) length.............. I'm surprised that they didn't duct ...

Re: Jim K. 3.2 engine

I've used Neway seat cutters on my 12 heads. They work very well, but frieght costs to Aus were a killa. Hopefully cheaper to other non-US parts of the world.

Re: Random Engine Torque Measuring Ideas............

Z, there are specific velocity probes so no problem. The question is what combination of velocity/flow you want! If you increase flow with porting it does not necessarily mean you also increase velocity. It may remain unchanged or even drop if you hog out the ports. To arrive at conclusive results ...

Yeah, the load cell equipped tailshaft is probably the best, but the pure cost of them.................... :shock: Motec supply them for the V8 Supercars to help keep the parity of all of the different engines. Any load measuring engine mount would only be in place for testing purposes. My main thin...

Random Engine Torque Measuring Ideas............

While pondering the purpose of the universe (maybe), a random idea lodged itself inside my noodle................. With the amount of give in 3 rubber couplings, could it be possible to monitor the torque induced difference between the engine's output and the clutch housing's input to give a meaning...

Re: Jim K. 3.2 engine

The reason I asked is that getting a 2.5 litre 24 valve is easy enough. But they are, as far as I can tell, the later engines. So building a 24 valve engine (obviously need new 3 litre 24 valve pistons) with 2.5 litre heads is out of the question because of the oil pump.

Re: Jim K. 3.2 engine

Yes they are huge on the 3/3.2. There's a thought to find some 2.5liter heads and measure those, but nobody has a set laying around here. I will not epoxy or otherwise weld the ports to increase velocity for fear of little lumps detaching... I have however thought of the possibility of fitting suit...

Re: Project 2 : front mount SA GTV 3.0 - Sei diff

Love your "extended" noise control measures Kev. :D My experience with slide on fixings is not that good. If corrosion sets in, they will bind up and become a pain. That is why my system is fully flanged in key sections and captive nuts welded to one of the flanges. I use stainless bolts ...
