where can i get some underdrive pulleys for my '00 LS?...
We aren't sure they will offer the hp increase that you see on other vechiles - someone will have to try it. One concern I have - the alternator output is borderline to meet the needs of the car - so you would want to ensure that you continue to spin it at it's sweet spot rpm.
Don't our cars have variable assist power steering? I think turning the pump at a lower over-all RPM could put the calibrations for the speed tuned assist into a bit of a mess... Plus, I have my doubts about our cooling system being up to par to allow the water pump to turn at a lower RPM too. Of course, that is assuming the water pump is belt driven on the same belt as the rest of the accessories. (I can't say that I remember for sure)
I'd be interested to see the results, but I wouldn't want to see them on my car... not without extensive evaluation time on someone Else's car!
I tossed around the idea of under-drive pulleys on my truck, and after factoring in my 35" tires (power steering), low gears (cooling), 750watt RMS amp, fog/driving lights and twin electric cooling fan conversion (alt.)... decided that perhaps sometimes it's best to leave well enough alone.
There is usually allot of slop built into production cars that will allow the running of an underdrive of anywhere between a 15-20% and still be fine. Testing will be required, but that is normal with any prototyped modification. I do not see it being nearly as difficult as you may think though. I highly doubt the variable speed power steering assist will be affected at all.
Well, I guess I just don't have THAT much faith in Lincoln!But like we both said... if someone takes off running with it and makes it work... Can't complain!
