cam follower or lifter ?!?

[Lee]

No idea Mark. Custom from a specialist Ti fabricator would be very very expensive. Its the people that only make valvegear and are able to process titanium properly that would be the most cost effective. Finding someone that has already done the 16V Golf stuff (if any) would be a very good starting point as you would pay less NRE (non-recurring engineering costs...ie setup/development charges).

Whatever happens though, Buying multiple sets in one hit is a sure fire way of making big savings. I spoke to a few people about knocking out 5-10 steel cranks, cost breaks on big batches of Carillos, Pistons in large quantities and you will be absolutely amazed how much money you could save. Getting 10 like minded guys together could actually make some of these mods much much more affordable....although still very serious and not quite your average Group-buy territory. Forged cranks only became cost effective on a run of a few hundred though :S. I am sure there are some nutters out there who would interested in a few of these. IIRC the first cost break on Carillos was 9 units and the next at 25.

how much more expensive do you think these components would be compared to steel, I'd like to do the same as you and go down this route maybe in the future?

Stop moving the goalposts

Stop moving the goalposts

LOL, probably by the time I can afford to do that, the engine will be going into a Zimmer frame .

Mark.

There never were goalposts Doug. Haven't you realised yet....there is NO END to the S2 modification. Once you start on the custom modification route there is no limits to what can be achieved. It is just a matter of time and money. LOL!

Large black hole opens in space, sucking Lee, Doug & Mark into a complete vacuum - devoid of all money to do anything else !!!



Classic thread - hey why stop at Ti valvegear - why not copy the F1 guys and develop a pneumatic valve system that can controlled by programmable software on a custom ECU. No lifters and wow - no camshafts - whoa betty - no timing belt either !

It's not money that is an issue - it is time - eveything just takes too long for me - it is starting to really pi55 me off. I'm going to bow out of this power thing in a couple of months - my pen1s - eh car - will be big enough by then!

Who has these camshaftless F1 engines? That was talked about a few years ago but the pnumatics would be far too heavy, and high up, for an F1 car - is someone running this now?

Same here, when I get the new engine built and in, I just want it running right..........something it certainly isn't doing now.
After thats done, other than the 'normal' running costs, I only want to spend money on cleaning the thing.

We are looking at moving home soon and the 'fun' will have to stop then.

Mark.

P.S. seeing those crash pictures recently (ZR's and those others), have made me think too.

[APNess]

I *used to* feel quite flush compared to you lot. In the last 2 months I've only spent 4 1/2 grand or so (I gave up trying to keep track now) with a couple more left to spend. Daren't tell the wife though - she could've had a new kitchen and now she'll have to wait a bit longer (like ooooh, 50 years). You nutters. It's like a slippery slope to oblivion, and bankruptcy. Not to mention divorce and eventual insanity (hmmm, lets see, check, check ,a cross, check, yep, got the list just about covered, though the wife may need checking out for staying with me!)

still no solution...

[olsonjus]

Anyone over here make any progress on this solid lifter conversion?

I've found this company that sells 12mm longer valves intake valves and 11.8mm longer exhaust valves for a solid lifter conversion:

Thread from the dead, and that statement is so true.

I have heard of RS4 lifters being used, has any one got any more info on this?

Cheers James

There is a guy on here that runs solid lifters on a 20v head, although i dont think he built the engine he could point you in the right direction.

Finchy is the guy and i think mark at automark did the engine for him.

Theres quite a few people with solid lifters, I am looking in to hydraulic ones. I have some that are good for 8300rpm with hardened springs but for just how long?

B7 RS4 ones interest me quite alot

What peak rev limit are you planning to run to then James?

We shall see, but at high rpm every thing is getting punished so much more, oil pump will start to worry me

I have heard of dimond coating of the drive helps pick up and prevention of cold welding
