Just bumped into this on eBay:

(Image tag doesn't seem to be working at the moment, dammit.)

Looks interesting, although the linkeage to the throttle pot would have to be good.

these were for sale on here a while back, they are lovely, but I have no idea if thats a good price or not.

there sh!t... anyone with basic milling skill cam make one in a day.

only good for full throttle driving (drag strip) and would last seconds on a road car due to small throttle moments wear the slide down causing random air leaks which cause erratic idle and low load problems

also dangerous because there is so much friction on the slide that it can stick open.
injectors been behind the slid mean at low load the fuel hits the plate... some will go between it and can easily freeze at full throttle

I see it now -- so side valve should read slide throttle. You'd need a pretty lumpy cam to make that worthwhile anyway!

yup you would need a cam with lots of overlap to ever need it but would be cheaper/better using a set of bike tbs

I have jenvey throttle bodies now anyway

Holy cow! So that's why you need the C & B bum sticks and the Carillo rods! :devil:

i could possibly get away with standard rods....maybe. but i dont want to risk it with a c&b300 on full revs..whatever rpm that is?

AND, Mr Croft wont work on engines with standard rods,so i'd struggle getting pistons, and my rods are nearly half the price of custom rods listed on his site....at £900

So what's Guy going to be doing?

designing the pistons and doing the head work hopefully

Have you looked into buying in the forgings and doing the machining yourself?

Nope, im not that good at machining. Id rather pay to have them done properly on a cnc machine. at least them they'd all be equal

why not save up and go cnc ?

its down to practice really, so you know making one off's could help you alot

lol do you know how much a proper cnc machine is? the tools alone can cost as much or more then even the best cento..

Does depend more than a little on the machine though. To do pistons you'd only need bottom end cnc -- the kind of stuff you see on Amarican Hot Rod. Somewhere near you a manufacturing plant is going to the wall...........

Still, it's amusing, perhaps, to think that the head is being done by a pair of human hands holding a die grinder while the pistons are done by some sodding great robot...............

Exactly that. All I do is a few flywheels a year for who ever asks then a few little odd jobs so it doesn't really require a cnc machine. And by the time I've written a program for the machine I could machine a flywheel freehand.

whitz got about 3 cnc machines in his house.

yeh cnc is a totally different skill even with the best software you need a lot of skill.
I like manual tools because you have full control over everything and go as fast or slow as I want.

with cnc you only need to put a number (out of the thousands) 1digit out and you risk crashing a tool into the work piece... or even worse... into the machine itself. (££££ down the drain)

Is this one a 16 or 8v? Either way I'd be very interested to know where he's sourcing the guides and valves.............

Might have a few machining jobs coming up -- rear blade type ARB -- if I can ever get round to doing orking diagrams.

Well then why am I doing machining work for him and asking me for more bits.

John, it's for the 8v.

Craig, I've done abit of cnc programming, we always used to test it on the computer before, but the lathe at work you just punch numbers in the box and off it goes,it's not linked up to a computer, but anyway, I'm not even aloud to use a lathe at work
