Great vid from Ashleys pug, looks like the grip situation is worse than ever there...
Once you have got new discs on the car can we please have wheel studs fitted, those 10x18s are bloody heavy

Like the plans for the engine, should really give the car a new turn of speed. A new exhaust manifold and slide throttles should make a difference, especially if you can get wilder cams in there.

no! well maybe, the main reason i've never fitted studs is that using bolts you can change hubs and discs without having to touch the calipers or pads

True, you just need to get Stephen down the gym then for those last minute tyre changes..

How are the sump bolts now?

dunno havnt looked lately, just spent last 4 hours porting a yb head!

Ooo, porting sounds good!
The gaskets I used to get for my old xflow were very good, I think they were like multi layer card so were soft enough to seal without all the squish you get from cork. I wonder if you can buy that material or replicate it?

[Graham]

Re: A race bmw 316, now S14 powered again!

i've made them from the thick card on the back of calendars before now, worked well

just spent another 4 hours porting that head, getting sick of the sight of it now! by the time im finished i'll have about 20 hours in it, no wonder you see so few properly ported, and just how expensive they are to buy done.

I really enjoyed watching the video from the Peugeot at Lydden, it really demonstrates the difference in performance between a turbo and normally aspirated engines.

The Pug seems to need to change gear just when you'd want it to keep revving and pull past the cars in front. It looks very quick, but totally different characteristics to the N/A engines. And the grunt from your BMW and the Escort is so evident. Its a shame Lydden had so little grip, I dont think the Pug would have got past on a better surface.

Great report, fantastic close racing, and I cant wait for the next event.

I'd love to have a go in my Fiesta, but the gearbox would put me in a very unfair class

Re: A race bmw 316, now S14 powered again!

The 306 is super charged and had 416bhp last time it was mapped,Graham had 270-280bhp and the poor lil crossflow in my Escort had 180bhp. Your engine would put you up a class or two on it's own ;-)

Power is nothing without controlOh unless you are on a long straight

you have the wrong engine so you would be bumped up the class's over that, the gearbox wouldnt have any further effect.
last time mine was on the rollers power was down to 250bhp! so i'd expect your featherweight fiesta to kick my arse.

if you like sprinting then dont go racing cos your never want to sprint again once you have raced!

Umm, hate to tell you this.......I'm entering a sprint at Goodwood circuit in august...unless I go rallycrossing that is.

Re: A race bmw 316, now S14 powered again!

enjoy, only thing i found is that after racing i really couldnt get excited about doing a sprint, especially if it was at a venue i'd raced at,

I'd only sprint at Goodwood cos I can't race there, rallycross looks more likely with the possibility of a full season next year.

Re: A race bmw 316, now S14 powered again!

i didnt fancy doing the next round at snet with rapidly growing cracks in the discs, although deep and wide enough to get your thumb nail in suprisngly they didnt go all the way through!

i opted to upgrade from the current 298mm which were origonally chosen because thats all i could get in my old 15" wheels to 323mm, TBH bigger discs add little to the braking power, because although ive gone up 25mm dia, its only giving the caliper half that in increased leverage, they should run cooler though which is a major plus point


going bigger still would of ment buying new bells as it was i put them in the lathe, faced off teh outside edge then turned them round and trued up the hub and disc mount faces to ensure everything ran true

i had to make new caliper mounts, not to hard thou the calipers and hubs both are 88mm centre to centre, so it was simply a case of marking and drilling 4 holes 88 and 29mm appart


finished artical.

new disc has a load more cooling viens, so hopefully they wont warp for a good while,


note the nice silver ARB, its a new one, after softening the springs the car seems to have better mid corner grip, but that hasnt helped turn in, so i looked at trying thicker ARB, eibach do a nice adjustable one, but thats only as part a front and rear bar kit , and supringly thin @22mm for the front, suprising because, high spec e30s come with 22mm, which is what i thought i had, only it wasnt when i measured it i found a 19mm bar on my car! in the end i bought a whiteline bar, much much cheaper and very thick at 24mm, so if it turns out to thick i'll make some sleeve to to make it adjustable, the only downside is a thicker ARB and bigger heavier discs have added yet more weight to the car
