I currently have a 15% pulley reduction. Would it be worth swapping it for a 17% one. Maybe the alta. I already have all the necessary bits to go with it such as gtt intercooler, spark plugs, cai, exhaust and manifold etc.
Whad do you think?

Ye why not? You have the GTT intercooler and highflow manifold that will expell more heat!

Hi Luka, a better bet would be the 2 piece GTT +1% ,+2% or +3% Crank Pulley (as you already have a smaller SC pulley.). This gives the boost and mid range increase AND the faster engine response due to the the low weight of our crank pulley . Best Regards Roland GTT

Hi roland, you already fitted the lighweight crank pulley to my car but the standard size one.

Lucachiarelli, do you have an AltaV2 pulley already fitted??

I have this puley in 15% reduction from minisport with reduced belt

1320autos · Sep 19th, 2007, 03:46 PM

Thats a pity as we have a 17% AltaV2 pulley in stock for testing so we could of come to an arrangement

If you want to spend a day and do a before and after dyno runs let us know

1320autos · Sep 19th, 2007, 03:49 PM

Though thinking about it might be cheaper overall to order another crank pulley from Roland and do before and after.

lucachiarelli · Sep 19th, 2007, 04:06 PM

Think i would rather have the 17% pulley instead of an enlarged crank pulley as i am happy enough with the lighwieight stock size one. Only had the crank pulley fitted 2 weeks ago.
How much would it be to have the 17% alta v2 pulley installed. Dont mind doing a before and after run.

We charge £283 incl vat and including free engine health check

lucachiarelli · Sep 19th, 2007, 04:12 PM

Think i might go for it in next few weeks as i am skint at the mo from buying porsche bbk and strut brace.
Thanks. Luca

Simple answer is depends on what you use the car for. As has been discussed at length on MINI2 the 15% seems to give better dyno results than 17% sometimes and often the 15% sees better strip results. However having driven cars with both 15% and 17% on the road i'd say the 17% often appears more powerful in real world driving conditions. Although the 15% is still almost up with it.

lucachiarelli · Sep 19th, 2007, 05:34 PM

I use my car for fast road use. Never drag or trackday.

I have just swapped JCW pulley and 3% crank pulley for 17% Alta V2 and standard crank pulley. Seems much better to me.
