I think i used the coupe turbo fuel pump in my first cinque turbo iirc its bosch and it has a blue bit on the pump? Nice car though are they compomotive wheels? Rim stock have started doing a similar wheel to them in 15inch i was very tempted to get some but getting some 14s

yeh compomotive wheels. do you know where i can get centres from for them?

non on demon tweeks. ill get some from compomotive 
just an update.
megasquirt running flawlessly and modified with the mods i did to mine to get the VR to work (filter caps totaly removed)
just waiting for a load of new wire to turn up and a driver from kritip.

anyone know if a 16valve crank is the same as the 8valve. I need to know if the shells are the same.
i THINK they are, since the rods are the same dimensions
youre not wanting to run 16v rods as well are you?

yeh i would like to. I have spoke to Tricker and he says he uses 16v pistons and rods. I also knew the rods from a 16valve are a better design.
not according to Peter (oldschool) they arent :shakehead:
He says that you wouldnt want to push any more than 120-130bhp from them.
to quote: "The 16v rods are weaker than the 75 rods. I would not use them for anything serious"
OP
OP
thats exactly what i would of thought... high reving high horse power engines have light weight rods and thin rods (ever seen bike rods?!) this is to lower inertia and bearing/piston side loading and even to the point of air(and oil resistance in the car of wet sumps) resistance.
low reving high torque engines have thicker rods... bit like diesels but i think that would be a bad example as our engines dont have half the combustion pressure of a diesel
What i dont get is that Tricker says hes almost getting 200hp from hes engine? has Oldschool tested this or is it just a guess?

he looked at them both and decided which he would rather have, i think.
the 75 rods are proven up to 150bhp+ in the race FIRE engines.
Then again, DtT's supercharged 16v must have been putting out over 200bhp to drive the charger AND provide 170bhp at the wheels... (then the crank sheared first)
and there are a few others i can remember that claimed they had 200bhp 1.2 16v turbos with standard internals bar decomp plate, but i think "claimed" is the operative word in their case.
Then theres another guy on SdP who is running about 135hp with a highly tuned n/a 1.4 16v revving up to 8000rpm...
dunno, its up to you. Maybe its worth giving peter a bell see if he will offer any advice over the phone?

I would like to think the 16valve rods will work better
ive got looked at a pic Tricker sent me (hope he dont mind me posting it)
8V rods are cast iron while the newer are cast steel.
It would be good to know the specs on both them but i dont expect they exists.
I would REALLY like to use the 16valve pistons with Ti cap bolts. this would have a massive decrease in big end side loading.

fair play! never knew the crack about them being different materials though.
I would get yourself on Spirito di punto forums and ask Peter (charlie on there) his reasons. Time the forum was livened up again anyway, its gone dead there

iirc it was the locating pin on the crank pulley that sheared, causing the timing to jump, thus junking the engine. the crank itself wasn't damaged.
My first engine was a P75 unit & my engine builders reckoned that 200lbft/250bhp shouldn't be a problem at all for the P75 bottom end once balanced etc. The same builders also weren't very happy with the idea of using the timing pulley to drive a supercharger as they felt it was going to be a weak link.
In terms of engine robustness TurboCinqy1250 was running about 160lbft/bhp the last time I looked, I think that was a P75 based install. My turbos engine was built from a MPI 60bhp 1242cc 8v engine, it's currently delivering around 160~165lbft and 185~190bhp & has been running reliably at this spec for a good 4k miles. For the record my P75 engine only expired due to human error during the rebuild processes.

he dosent go on it no more, that is why its dead

why not
since its HIS forum, after all
