Pulley kits

[Herblenny]

If mainly driven daily and occasional pulls on the Hwy. I would just stick with stock pulleys.

I say this to FD guys all the time... If you are just pudding around, no real reason to get all these under drive belts.. Reason for underdrive belts are so that at high RPM you don't over drive your alternator and your water pump (which at high RPM cavitation occurs). If you drive at low RPM most of the time, benefit is minor and negative effect is also minor as you are not in high load area...

Some say these aluminum under drive pulleys are light and hence you might gain responsiveness of the engine.. which could be true.. But I also noticed better response by just plugging in HKS twin power I guess if you start adding all the minimum HP gains, it will eventually worth something.. But as an FD owner, Its nowhere what you could gain from just turning up the boost a little on an FD..

I just feel that some people are spending WAY too much money to gain 50-60HP on renesis and at the same time reducing the reliability of the engine. Its almost better to buy a used FD as a spare car when some people are dropping 5-8K on a turbo system... or just putting 13B REW with stock twins, you'll make more than some of these turbo kits available for Renesis... My 2 cents.

I agree..

The Alloy pulleys I have (not under drive) are a lot lighter than the std pulleys, very slight gain responsiveness , but to anyone who is not tracking/ racing there 8, .... Not worth the money spent.
And the under drive pulleys, which were $100 USD more than one pulleys I bought, .... Unless you are pull 7000 rpm and upwards ... all the time.
Totally waste of money.
My 2 cents worth, which in NZ cents... is worth less........lol
