how much was that o-ringing in the window, woof woof?????????????

how much was it to do that to pistons?

what head you using and what compression you going for?

i still want to know a-15 standard compression too?

o-ring and pistons not sure of price as jeff taylor of jts fame did it and gave me one bill for all my machining.( he is pretty reassonable)
Head is a ported a15 item with larger valves.( I think I have a pic on here of it)
Comp jeff calculated to be around 7.5, 7.8-1 if i remember correctly
Standard comp- phuknose

does anybody know anything about hpc coating? coz i am lookin at getting it done for my a14.

We better check this site for terrorists. Someone has hijacked MadTimos thread

The standard A15 compression ratio is 8.5 to 1 (at least in the US).

A ported A15 oval-port head is said to flow better than an A12 GX head.

Yeah, hey...whats goin on here??????

hahaha, thats cool it made good reading anyway.

Anyway...does anyone of know of anyone i could talk to about doing head work, choosing cam that sort of thing, in the Sydney area?

there is a fellow i know of croyden engineering i think it isi'll find out for sure 2morrow for ya he is very good

Yeah. that'd be good thanks dave. If you could get me a phone number would be nice too.
I really have no idea who to talk to bout these things

just sticking my nose in,why not talk to arthur jackson at the road & rally centre on 02-9645-2143.arfa's a very smart fellow,& i have yet to blow up any of the motors he has built for me.he's a very laid back sort of a guy,but knows his stuff.warning,he is expensive,but i've always thought it was worth the extra.

And I'd fully recommend Jeff at JTS - I'm yet to hear anyone bag one of his motors and he's done a heap of them.
