GARETH T

been busy on the lathe have we ian?

i couldnt get the top hat to work right when i done one

ian sibbert

Cant beat a bit of swarf pal.....

Tapers can be a bitch to do....

GARETH T

how do u get the old valve out ive undone the 2 bolts does it just pull out as it seems stiff as fook

GARETH T

pull like fuck

ian sibbert

Brace yourself and put a cushion down......big mole grips....one good yank....job done....

ian sibbert

Ive got a collection like that...lol...some slightly more charred than other....

GARETH T

its completly home made,,, even the bobbin,, so i can see this one getting charred

i have got an other idea i wanna try,,, might start making it next week! a revolving plug in the throttle body

Ryan

nice work gareth.

also, can u PM me the info you sent me ages ago about the Stack speed sensors pretty please

got it out

ian sibbert

Hmm I think that would be the way forward....coil looks the business pal.....did you wind by hand, or do you have a posh machine at work....on second thought, you probs made a machine...... you giant brained welshman you....

GARETH T

no,,,,

Roosie

what size is the nut on the end its tiny

GARETH T

i spun it on a lathe mate,,,, problem was i couldnt find any new lacquered wire,,,, so i unwound an old coil onto a bar,,,then wound that onto my new bobbin,,,, bit of a bodgy,,, but i wanted to try it!, it works as a coil,, but havent seen if its strong enough of the car yet

GARETH T

3mm isnt it

Roosie

iTrader: (8)

what a size only go down to 5mm

ian sibbert

I did work out the length an size of wire necessary to lift the valve I made....

This the wire we used....

GARETH T

how did you work out the energy needed to lift your valve?

did you do it force=pressure x area, where pressure would be the differatial pressure across the valve area,,, and of cause area being the valve area?

GARETH T

there worth nothing mate,,, post them to me and ill dispose of them in an environmentally friendly fashion

Roosie

iTrader: (8)

are they a direct replacement ie ubolt mine and put this on? what causes them to stick

GARETH T

you need to machine (or cut) the end of the idle valve off

ian sibbert

yes... I cant quite decide if you would have a differential across the valve though....its subject to a vacuum on the plenum side and its that pressure it has to overcome....along with the weight of the valve itself and any return spring (if fitted)....we perfected it with a little trial and error...i reckon it would work, but might be on the top side of the output from the ecu.....

big job or can a trained machinist do it

GARETH T

i hope your not near the 10amp output of a t6
,,, 120 watt

GARETH T

a trained machinest should be able to a the top hat aswell you lazy man

ian sibbert

I wasn't doing it based on the T6 but more for the mass market P8 etc....and I ran out of time to really develop it....

Roosie

im useless with my hands to be honest.
prefer to just goto a machinst say cut that off and stick this on.
i would just drill the holes out but i think the als will be to mild for my liking.

GARETH T

story of my life mate i wanna give up work and play,,, but sadly the band wont let me

midnight_man

IS necesary to change ECU software When I want to change standard drilled ISCV for TOPHAT one? I have MSD antilag in P8.

Thanks
