hi all, has anyone carried out the pully wheel mod and if so what was the benefit and is it worth doing

Have a look at the powerhouse web site. I ve been toying with the idea myself. A bit more mid range pull I believe. Please let me know if you get it done. Have you chipped it? Worth doing, I'm up to 420. Cheers

not realy interested in the chipping or the remap, the pully wheel is the one im interesed in

please let me know how you get on with it if you do.

You guys should contact MSL performance based in Birmingham.

here you go mate

hi, did you get this done?

I've had it done on my SC, but, in conjunction with a Quicksilver Sports exhaust, chip tune and free flow air filter.

The combined effect is staggering acceleration, mid range everything is much better, to the point the gearbox almost 'struggles' with the power delivery on full acceleration from low speeds once you hit the yob spot over 3000rpm

The garage reckons having compared it to a standard 2007 SC and a 2011 5.0l SC that I must be running close to 475bhp

Can't help you if the SC pulley alone is worth it, but the package I got definitely is, gives me major grin factor on the way home every night, as the speed piles on sooo quickly...

thanks. i'm modded to your spec but not the top pulley so was still in thinking but i think you've just made my mind up.

Guyzer73 What was the cost to get to your level? this sounds like a really good idea.

I can see they do a Lower level Pulley upgrade and a Upper level Pulley upgrade, what do these mods do? is it a gearing change? 2006 Supercharged

Sorry guys, just read about the mod and it is a gearing change.  2006 Supercharged

Paul,

I'm not exactly sure as I did this about 4 years ago now. For the Quicksilver Exhaust you can check their website to get the UK price.

With regards the SC pulley and ECU remap I used a company called VelocityAP in the UK. I can only find their US website now and they quote a huge amount for the SC Pulley and ECU remap. I didn't pay anywhere near that. I think it was about GBP 400 for the ECU which I sent in from Oman and another 250 for the pulley.

I asked them to tune it aggressively as I didn't have concerns about fuel economy

Cheers
