Supercharger Pulley

[BlackOutS]

I know it has been under a lot of deliberation, and everybody has their own veiws on it- but what do you guys think is the best to go with?

People say the 15% is reliable and works well

I haven't heard too much about the 17% pulley

I have heard that the 19% pulley can eat up belts and create too much boost

I am about to buy my Alta pulley, which one should I go with?

Scottsdale, eh? Another Phoenician!!!!

If and WHEN I do it, I will probably play it safe... 15% for me! Wife would kill me if I did something to the motor! I was already told, if anything happens, I'm walking to work!

update your poll to include the jcw 13.5% maybe

The JCW pulley is a 14.3% reduction ...

19% if u dont go to the track
the low end power is so nice.

oops. i've read so much conflicting info, i could just have easily have said 4.79%.

ive seen people using 19% on track... without much problem, i've also seen alot of problems with 19 tho...

i'd think a big intercooler would benefit the 19 quite a bit... personally i love my 15% but if i'd do ita gain i might try the 17, as it is just at the limit of the supercharger...

I'm thinking about going with the 17% over the 15%. I decided a long time ago that I wasn't going to get the 19%, but I put it in the poll anyway. This is my daily driver so I don't want anything that is risky to the motor. The 17% seems pretty safe just as the 15% is. I will probly order my 17% tomorrow, unless somebody can convince me otherwise...

i changed from 15% to 19% and no regret

[bkwalker]

ive got the 15% ... it is awesome, but if i were to do it again, i would prob going the 17%..
im not sure how much more power you would get. but i think the more low down power the better.

its a hard toss up... im getting an ECU as soon as i can afford it, and that will prob give me the same juice as a 17% or a 19%.. i dont know..

but you may aswell save yourself the cost of the ECU and get the 17%..

19% would prob be safe, but there is that 'possible' risk.

i have decided to go with the 15% pulley. Here is what Alta had to say...

"For long term reliability of the entire powertrain the 15% pulley is certainly the best way to go. This still increases HP but does not go near or beyond the thermal efficiency of the S/C. Both the 17 and 19% begin to push the envelope to and beyond the safe levels. Both are ideal choices for consumers that demand the fastest stop light performance but don't routinely maintain RPM's at WOT in excess of 6K RPM. Extended use in the upper reaches of the RPM band with a 17 or 19 can compromise the integrity of the S/C. A larger top mount intercooler is a near must with either of those choices while only recommended for maximum performance with a 15% pulley."

So you did notice a good increase with the Superchip? Trying to narrow down the ECU list for myself!

i noticed ALOT ALOT ALOT... going to dyno this week. stay tuned....

can i get a link to the page where superchip.uk sells the mini ecu? did you buy it straight from them or a dealer of some sort? im thinking about going with the shark injector ecu reprogrammer, but i will check the superchip out before i make my decision. thanks.
