Can anybody tell me specs of a standard 1098 camshaft (or MkI Cooper S I think they're the same)? I know 998 camshaft isn't so good but I can't find info on what my 1098 cam is (or might be - not sure if the cam is original spec or not).

Cheers,
Anto.

Sorry Christoph just pointed out it's in the BMC manual. 5/45-51/21 that equates to 230/252 duration - not *that* good! The Camtech 620 is 260/252 so that should be an improvement over my current cam.

Anto.

Timing is 5-45 inlet/51-21 exhaust, valve lift .318" approx.
Inlet duration 230*, exhaust 252*.

Regrind the sucker if you want it to GO!

Something around 270* duration goes nice in a modified 1098.
Bobtel's 1152 flies now, it's got a Russell Engineering:RE-13 cam like mine. But it's got a bit more than 270*...wink:


Be careful with Camtech cams. Very pointy lobes...I had a #619 (VP3) it wore the lobes down halfway in 40,000 miles..

I'm thinking if I do port the 202 (when I get some money!) I may aswell get an RE-13, if I'm going to bother - go the whole way in the first place No point atm with the smog head - it wont rev past 5,500 rpm!

The camtech is second hand too - if you are right then it could be pretty worn as it is.

If it's not worn bad you maybe can get it reprofiled. The one in my car now was an S, then a Bert Jones, then a 731, now it's an RE-13...

Heh if it wears I got a virgin ground one..

Graham's cams all have a nice big lobe radius..

My cam had been ground at least once before i got camtech to put a VP3 grind on it, like kevs, and like kevs mine chopped its lobed of pretty badly, luckyily??? i snapped the crank after about 30 od thousand KM's? due to a dodgy grind and detected the problem (or graham did)

The point im trying to get to being he was still able to grind his RE-13 onto my cam..... So theres every chance he will be able to put another grind on it

G

Alltought you are in Canberra I would still give Mr Russell a call for what he may be able to do
Number one in regrind cams

Bobtel is now running an RE-13 in his bored 1098, with twin HS4s etc it kicks ass (or is that arse?).. anyway it flies!

kazjim has one too (with modified LCA) in his turbo 998. It truly is a cam for all seasons..

That CAM is probably very confused!! I wonder if it hankers sometimes for the days when it was a brand new S??

Heh, it won't be getting any more grinds! It just cleaned up..

[quote="drmini in aust"]The one in my car now was an S, then a Bert Jones, then a 731, now it's an RE-13... quote]

Does that mean it was a 731 and GR made it into a RE-13 ...Interesting or was it a new one

There's enough meat on a stock Mini or S cam to do a few regrinds, unless you're talking race profiles...

(Many) years ago, I got a factory 731 cam from a mate who worked in BMC's plant. He had run it in his Cooper, and it had one badly worn lobe.
I got Bert Jones to grind a `master' (like a template) from it, and then regrind onto an S cam.

Fast forward to 1980- I bought a `68 Cooper S that had a Bert Jones cam, it was a POS grind. So I got Bert to find my master and put a 731 grind on this cam.

A few years back I needed more grunt when I started running my red car, so I fitted the Camtech 619 (VP3) one in. When it wore out I pulled this one out of my stash and got Graham Russell to grind it again, to an RE-13.

BTW the duration on this cam is around 277* inlet/286* exhaust.
