Replacing the Pulley on a Blower

If I wanted to change the blower pulley on my 02 SC would I need to get a chip for the computer? Or have the computer reprogrammed or anything?

What is the most effective pulley that I can put on there? And what kind of gain would I look to expect?

Oh, and where can I pick one up?

If you have a series II blower Chicane makes a 66mm pulley for them. You need to get a better fuel pump as many have blown their engines doing this without a upgraded fuel pump. Get a SVT focus pump and you should be fine, as well as a tune.

I just ordered for my 02 Saleen from Chicane... http://chicanesport.com/
They say you can expect up to 30 HP...You will need a bigger fuel pump and a new belt to keep it from slipping...Also it will run either rich or lean w/out a tune... Geting mine tuned on thursday and will let you know what I got from it...

TIM

with pulley comes
1) Tune
2) Smaller Belt
3) SVT focus Fuel pump
4) 42 pound injectors
5) 90 MM Maf
6) ngk tr6 plugs

If u dont do this u will bloe your motor

What is this? And what will it do????

6) ngk tr6 plugs

It is a spark plug.
1) Tune(yes)
2) Smaller Belt(yes)
3) SVT focus Fuel pump(yes)
4) 42 pound injectors(good for hp)
5) 90 MM Maf(good for hp)
6) ngk tr6 plugs(good for hp)
I put the ones that are essential the others are good to boost your hp when you get tuned.

Ngk Tr6 Spark Plugs gapped at .038

Cool, thanks guys! I am hoping to get 400rwhp

Good luck!

Not with the series II you won't. I would go kb for the amount it would cost to even get close to 400rwhp.

Are those cooler than the stock plugs?

Yea they are, there supposed to be the coldest.

I put those spark plugs in but was told to gap them at 32*...who told you 38?

Thanks. I only have 12,000 miles on the stock plugs but will be pulling some stuff apart on the motor, so I will likely swap the plugs out.

So if I put the 66mm pulley on my stock 02 I am going to blow it up?

YES

Unless you upgrade your Fuel pump, injectors, MAF, and Tune.
