ALLOY PULLEYS

[LEONMEX]

Im having made for my escort some alloy pulleys a bigger pump pulley & bigger alternator pulley & alloy crank pulley for my pinto,the idea is to stop overcharging & to help with overheating when on track. Im having them made from billet alloy,would there be any interest if the company made a few sets of these?? They reckon should release about 6-8bhp just through the crank pulley as its lighter?? They do them for zetecs at £200 a set.

sounds nice tho what sort of cost for the pinto

[LEONMEX]

I reckon on the same for the pinto but my car is the test engine for these so depends how it goes!!

Less Weight will not increase HP!!!!!

Esslinger Engineering (usa) make bigger pulleys !

 

Prob cheaper to get 1 shiped over than to have one made !?!?!?!?

 

P.S. if you go on there website, take a look at there 2.5ltr PINTO.

p***ed on my matches then? they done some for a zetec & got 8bhp more through replacing 3 pulleys.

Are you planning on spinning the water pump faster to help with cooling

The esslinger pulleys are HUGE!!! Which would spin the pump slower surely??

[LEONMEX]

Was planning on bigger pulley to make it slower as on the pinto it just frofs the water up and dont circulate as it should when reving above 7k for a long period of time. Not my idea im just the guinea pig

Take a look at the Midget ST and XT engines too

[LEONMEX]

They do the big pulleys same as im having made the stuff on there is the nuts.

I uderstand what you were saying about the standard pulley spinning the pump too fast at high revs. So fitting a bigger pulley obviously helps there, but surely it also means the pump doesnt pump enough at lower revs? So your engine overheats.

I run a power grip pullys on my pinto with a standard waterpump but I use a transit DI rad c/w twin elec fans & a swirl pot she will sit in traffic all day

I like the idea of Leonmex being a guinea pig lol, we'll see if his overheats in traffic

As Ian mentioned there is no measurable power to be gained from them being lighter, but the crank driving the pump and alternator slower would, although 6-8 bhp seems a bit high.

I made a smaller ally crank pulley for my Essex and a larger one for the alternator, plus a larger steel one on the waterpump. So when the engine is spinning at 8000rpm the water pump is doing the same rpm as it would at 6000 with the standard pulley, to prevent cavitation.

As for overheating at low rpm I couldn't say because it doesn't have any cooling fans fitted and doesn't do slow

[petrolhead]

I'd have to agree with that. Light weight will not add power only allow the engine to spin up faster, like a lightened flywheel effect but less pronounced. There is logic to the argument that if it drives the water pump slower less energy is being used but I would have thought the power saving would be more like 0.6-0.8bhp than 6-8bhp.

Well ill find out & let you all know when i get them back (obviously i wont say to much if it overheats in traffic lol) but will let you know if it makes a difference or not!!

[escort21]

£200 quid....jesus, i best start making them and selling them
