Re: a very powerfull and troublesome bmw 316

cheers chaps

now the dry sump drive is sorted i need to attach my new trigger wheel, i dont have much to attach it to either, my engine doesnt have a front pulley as such, just a modified crank boss form a big six bmw engine

unfortunatly wherre i needed to attach drill and tap holes for teh trigger wheel some overlapped with teh origonal holes that the big six engine uses for bolting on a crank damper etc, so i locteded bolts into the holes let the loctite set and cut the bolts off flush with the boss



next was to drill and tap holes to take the trigger, and make a new mounting bracket for the crank sensor as this trigger is smaller in diameter than my origonal one



as you can see the dry sump pullet fitted very close! infact i had to machine down the pulley to get a fraction of clearance for the bolts, still i no teh bolts will never come out and if they do im alreay in deep trouble because the oil pump pulley will of already fallen off!


to get the oil pump pulleys to line up i had to thin down the crank boss where it meets the crank so i now need to thin down the timming cover also!!




lastly a pic with all the pulleys and timing cover on, so in theory i think i now have the bottom end all sorted

Re: a very powerfull and troublesome bmw 316

Glad to see you got it sorted Graham, thats quite a large pulley on the oil pump isn't it

its a 2.1 reduction, the pulleys only look odd because were used to seeing dry sumps driven off a pintos aux pulley which is rotating at half engne speed, where as im driving off the crank

Very nice M8, that lump will make 500 with a bit more puff

not so 250 would be ok, although im secretly hoping to see more

as im going back to my N/A roots theres no turbo this year and only a 8 valve head, should be just fast enough to show mr white the error of his ways

GB,

Huh.

The Pinto aux drive turns 1/4 speed, of crank, like cam [4 stroke] so should be 1 to 1.

4 to 1 crank driven

2 to 1 is too slow in my book,.... but whats pace say ?

[Graham]

Re: a very powerfull and troublesome bmw 316

roger cam shafts turn at 1/2 not 1/4 crank speed!

pace spec'd both the pump and the pulleys to suit my specific engine so if 2.1 is wrong then pace got it wrong!

interestinly the pulleys in the pic of the crank driven duratec in that pic look very similar to mine

Well we have very similar cars, it all comes down to who has the better engine builder
