found my boost wippeeee and guess what.
Turbo Mini Forums

found out where my boost went , well it didnt get there in the first place.

after a lot of twatting about, found my super head and a bit of debris jammed between the inlet valve and seat aso it has marged the valve and the seat, about the size of a piece of hard small dia wire, so the head will either have to have a bigger inlet valve in or have some inlet seats fitted.

any way after putting my old head back noticed that my bottom hose was split were it goes onto the water pump so a few choice words were said, but then a ray of light shone over ones engine and there layed the boost problem right in front of ones eyes.

i though there seems to be to much clearance between the bottom hose and the turbo inlet hose, and yes the inlet hose was laying at a 45 deg angle rather than straight at the inlet.

as the wire reinforcinghad worn a bit which allowed this to happen.

so there you have it when comming on boost the inlet hose was collapsing starving the blower of air thus boost was dropping of.

quick cut down of the slack bit and replace, fitted head she went realy well to tescoes at ipswich then wondered why the engine was a tad hot then relised one had forgotton to do up the thermo hose and lost a bout 1.5 ltrs of water.

on way back i think the head gasket went as steam was coming out of the breathers, so head of but couldnt find anything amiss so just hopeing that it was the gasket as number 2 was down to 80 psi instaed of 140. either that we have got some serious problems.

Were you using that flexible ducting stuff?

I don't like it for that very reason... I always use silicon hose.

yes nice one mate, at last you might be getting there. Dave he is using flexible pipe but it was the reinforced type.

1/4mile in 13.2sec @ 111 terminal on 15psi

cheers boys, i will fit new gasket tomoz but still not 100% happy until i know she is running fine.

still smokes on lift off but i can live with that.

yes mat it is wire reinforrced but silicon may be a option along with some proper bent pipe. because that reinforced stuff doesnt last long for the price as its about £30 a meter and i have a big run of the stuff as i dont have room under the actual bonet to fit a decent sized filter.

the only othe option would be to fit the smaller filter some were. best i talk to DR WHO i think.

oh that bloody expensive intercooler works a bloody treat.

given it plenty of been on 14 psi and i didnt seem temps above 40 deg

hi jimster yes went for a pace cooler made to measure jobby with 50 mm cores.

but doesnt matter now as the hog is dead.

number 2 cylinder rings have shot i think as she is low on that cylinder , i changed the gasket but she still runs on 3 with plenty of exhaust smoke coming from breathers so thats it for the year and thank f'ck for that.

now i can rip her heart out and shove it in the bin and start again for next year.

plus i will be putting the clubby back on the road this year hopefully.


there was a pic put on here a whilst again about 2 weeks i think so have a look mate.

Oh no, unlucky
Light at the end of tunnel at least if youre making a brand new engine.

Back once again like a renegade master

it was a brand new engine mate only done 1500 miles. so back to the drawing board

always looking for them bigger bunches of bannanas

REALLY sorry to hear that matey.
Is it just a piston ring?

Back once again like a renegade master

i recon, i had trouble with nu7mber 2 to get in as the ring compressor wasnt done up enouth so my guess that the rings have cracked or chipped.

what ever its fu@cked now

but engine is ready to lift so on monday we will see.

always looking for them bigger bunches of bannanas

Mr Hogster, how many enignes have you built? Think it's a few so take it popping pistons in is a critical bit that can go wrong?

oh yes its certainly is. built quiet a few now and this is my first proplem so bound to have one at some point.

always looking for them bigger bunches of bannanas

oh ass

do you think it will be salvegable with new rings? or is it going to be a complete new jobbie?

dont no nic i will find out later today.
