Nice one Grahamdo you think you are still on target for the start of the season?

[Graham]

Re: a very powerfull and troublesome bmw 316

maybe, i could probably assemble the car but money is going to be a real issue having been off work a couple of weeks with back trouble

Re: a very powerfull and troublesome bmw 316

Sorry to hear about your back problems mate,nothing worse than being off work but not being able to do anything due to injury/illness

Sounds like it should be a bit of a beast when it's finnished

Re: a very powerfull and troublesome bmw 316

finally it feels like somethings happening

got my seat, belts and fire extinguisher in on sunday



been more busy since, wired and plumbed the fire extingusher, and the hard fuel lines, you can just see the 3 of them bottom right of picture, 2 feeds 1 return


plumbed and bleed the brakes

started on the wiring

gearbox and prop on and clutch hydralics bleed

Looking good Graham

Re: a very powerfull and troublesome bmw 316

ever since i bolted exhaust manifold complete with turbo, adaptor etc the weight of the whole thing has worried me, despite my damper/support mount, the it dawned on me that the majority of the manifolds expanion will take place at the hottest bit closest to the turbo so that if i supported the manifold close to the head i would hopefilly be ok, so here goes nothing and using some spare ashley exhaust clamps ( see ashley stuff does fit sometimes lol) i've used the coolant rail to support the manifold



then added a support under the manifold,


this pic shows just how tall the whole turbo/manifold assembly is



back in the car at last ,
no real hitches fitting it, the n/s engine mount needed some "perswading" but thats often the case when you fit something for real for the first time having only previously mocked up so many modified bits

Re: a very powerfull and troublesome bmw 316

sorry to hear about youre back troubles Grahamon the other hand im glad to hear the engine dropped in without too much fussthat turbo looks huuuuge on there.lets hope the supports save a once before problem out on track

Good to see some progress going on Graham.

Re: a very powerfull and troublesome bmw 316

Nice work graham, doing better than me and my backs fine

As for the efi pump and it returning to the tank most of the time, will you not run into fuel heating problems with the friction of constantly being pumped round the return circuit? Hope you understand what i mean, iv confused myself with some big words

hopefully not! thats same way it worked with the facet pump, as the swirl pot is a free return theres no pressure in that part of the system, and the pump will take minimal electrical load because its not working hard so that shouldnt heat the fuel, with the engine at full power there will barely be a dribble going back to the main tank, with a big alloy tank, i dont see really cant see it being an issue anyway, not forgetting that i never race for more than 20mins anyway with most races this year scheduled for 15min

thanks for the interest and your imput dave, its nice to know someone actually reads this drivvel i write, oh yes thanks also to the other daves, tom, andy gary etc and everyone else

Re: a very powerfull and troublesome bmw 316

is it not a bad idea to have hard fuel lines plumbed through the car, as in the event of a crash arent they more likely to split and spray the inside of the car with fuel!!

This was my reasoning for running the fuel lines under the car but i am runing a road car not a race car.

on a race/rally car its standard practise to run the fuel lines inside the car, far less chance of damaging them or ripping them off on kerbs, gravel traps you name it.

for safety reasons the rules say in car fuel lines have to be either metal or braided, your pretty unlikely to split open a metal fuel line, sqwash it maybe, either way your never goung to fill the car with fuel, the moment the fuel pressure drops the engine will cut, as soon as that happens the ecu will shut off the fuel pumps anyway

[tom burgess]

Re: a very powerfull and troublesome bmw 316

Al's old escort dont have an ecu to shut off the fuel.he has holes to let it drain out instead

Re: a very powerfull and troublesome bmw 316

after getting the oil filter housing complete with cooler pipes and oil cooler on, i put some oil in the engine connected the oil pressure gauge and using a battery and some jump leads directly to the starter cranked the engine, and cranked and cranked and cranked and cranked because of the huge oil cooler and pipes plus the turbo to fill it took an age before i saw any oil pressure, eventually i did, and out of interst kept cranking to see how high it would go, nearly 60psi was the answer!

Re: a very powerfull and troublesome bmw 316

with the rad, turbo and intercooler in it was time to try and plumb the coolant return from the engine to the rad, the new turbo location meaning neither the 2006 or 2007 setups would work, it took a while but i got there, at the monet the hoses are only mocked up, the hard bit was trying to do it using only stuff i already had, got no cash for buying new bits
