After getting my exhaust, next is underdrive pulleys. What would u guys recommend, and whats the difference between lets say 24,25,42%?..also what would installation set me back. btw i love my exhaust its getting deeper/louder everyday.

 

ASP Underdrive CRANK pulley is all that is really needed. Those percentages are how much it slows everything down. I say just get the crank ASP its all you need.

 

^^^^^^^^^^^^^^^^^^^^^^^^^^
What he said. BUT, I do like my billet water pump pulley! Plus it was getting close to time to change the belt, so I bought the whole kit. The % is actually how much smaller the pulley is. I got the 42% so it's 42% smaller than the original's size. Plus it transfers more HP to the rear wheels than the 25%.

 

yeah its been so long i talked about pullies since the blower that i forgot about the % meanings...thanks!

just get the CRANK once again...you can always chrome your pullies LOL

 

what size belt would you need if you got the 42% underdrive crank pulley?

 

The kit I got from www.rpmoutlet.com came with a new Goodyear gatorback belt.
If you buy just the crank pulley, they got the belt there too.

 

yeah i think the pulley thing would be good for me since i have exhaust and k&n. seems to be a good third step.

 

Next..save your pennies and dimes for a Flash Tuner. Either the Diablo( I have this one) or the SCT

 

Yea i can't wait to get my pullies, that is 4th on my list right now.

 

i was thinking 42% but does everything still work ok like the water pump and power steering
