matt47569 Member 39 Member For: 15y 6m 7d Posted 14/11/10 12:16 PM Share Posted 14/11/10 12:16 PM has anyone here fitted a 20% underdrive pulley kit to their xr6 turbo? and what results did they get?a 10rwkw gain is claimed for NA and turbo engines but have not seen one done on a turbo motor. I understand this is probably because it's seen as a small gain for the money which could be better spent elsewheresince my car is an xt that I've put the turbo bits on, I want to get the most out of it without taking the boost past 10psi which would stress the engine too much Link to comment https://www.fordxr6turbo.com/forum/topic/31618-underdrive-pulleys/page/18/#findComment-1055873 Share on other sites More sharing options...

Yeah I can understand that there are lots of other mods to do to turbos, but ive done my first round of mods and not prepared to spend thousands on a exhaust or new intercooler so just looking for a cheapish mod.

Getting a few extra kw from a few hundred dollars with 100% extra risk is defiantely not worth it!

The N/A boys have no other choice as they cant up the boost. By all means do it, but your money is best spent elsewhere.The motors are no different and you will probably see similar gains to the N/A boys. INTERCOOLER should be your next mod. 304 on the dyno but probably 270 or less on a hot day.
