Underdrive pulley kit

[gavink]

No You just need a shorter belt

Thats good then saves me £100

Do people just get the pulley\'s for show then or is there a performance benefit also??

Clive- stand corrected :god

The pulleys under drive, so suck less power.

So should release a few ponies- not much I\'d expect, but it all counts :p . Reckon higher BHP, ie single turbo conversions, etc would benefit more from this.

Depends on a few factors such as engine conditon, etc.

I\'m running similar mods and have managed 322.9 at the wheels- see my ride in members section for details + power graph!

This however is reaching the limits of stock cooling(intercooler/rad) and fueling- indjector duty hits 100% in high revs

so next steps after this would be aftermarket intercooler and fuel pump and injectors, to be honest the engine prob isant in that great a condition has done 65,000 with no rebuild.

[tr1cky]

You\'ve got it!

Might be worth think about a rebuild before intercooler+injectors though.

More power equals more stress! Better(+cheaper) to rebuild a worn engine than a blown engine! Be worth porting while it out too!

was thinkig of going for a street port, have been to Ross at Dragon a few times and have lookedat his prives, about 3500 for full rebuild and street porting, wont beable to afford that for a while, anyone else anyone can recommend who can do a good job?  i know people have there own tuners they go to, im from the south west of england so dont wanna travel to far

[tr1cky]

Ross is the nearest then- bit of a trek to anyone else.

Although might be worth finding the price of a rebuild from Tim at RXmotors- they price always seem reasonable and would be the next nearest to you.

where abouts is rx motors?? re worx cnt be too far from me down in portsmouth thats where turbomaz goes and he lives nr me, so i might get a quote from them aswell

[tr1cky]

RX motor are in Dorest.

Yeah RE:Worx not to much further really- They did the work on my car- Top job and Geoff and the boys know what there doing!

Think I\'m lucky really- RE:Worx only 15miles away and Carl(hayward) and RX motors in close range!

[ro284]

RX motors are on the road from Salisbury to Blandford turn right about 3-4 miles before Blandford, bit difficult to find though, somwhere near Maddona\'s place!

You can get the belt from halfords but it\'s only 4 ribs instead of 5. I have had no problems with it in the 2 years it\'s been fitted.

[royston1xx]

I just looked at my paperwork and the belt length needed with stock pulley\'s and no airpump is 750mm.

[chrisJDM]

have rxmotors got a web site?
