Get the 4490s if you are after low end torque. Get the 4495s if you are after high end torque.

"Under drive pulley systems increase engine horsepower by reducing the amount of power required to drive external engine accessories. For example, the alternator, power steering, water pump and air-conditioning compressor rob horsepower from the engine. By replacing factory-sized crank and accessory drive pulleys with a resized pulley, the accessories are slowed, resulting in more horsepower available to the drive wheels. Typically, a set of pulleys from B.P.T. will increase power by 9 - 11kW's, and increase mileage. All pulleys are manufactured from Billet steel and aluminum, exceeding factory quality. All pulleys sets are fully neutral balanced at the factory."

Great thanks for the info

Where do we buy one from ?

Easy to DIY fit or not ?

Ahh the age old 4490 vs 4495 debate. For what it's worth I think Doogstar (he can correct me if I'm wrong) was running with 4495s when he ran his 13.75s 1/4 mile.

Personally I'd prefer 4490s for the lower down gains for day to day driving on the street.

Yeah I am more leaning towards the 4490's.. Just looking for prices

Let me know if you find any decent prices/places jimbo!

cheers!

No problems mate, The cheapest I have found so far is $435, MAYBE if we can get enough people we can organise a sorta group buy?

180.7rwkw after todays tuning at CV Performance

Running 95 premium too so it might have been a few higher with 98

It was at 153rwkw stock and after ph4490, cat, xforce catback, cai and a capa flash tune it was at 165 so not much of a gain without the custom tune

That sounds like an idea..I think I put it in the 'ideas for group buys' section along with the underdrive. ill see how that's going.

A bit less than 3k for flash tuner, custom tune, CAI, exhaust, cat and ph4490 including fitting.
