Downtown 300 / Re: Dr Pulley 20x12 14GR
« on: May 12, 2013, 07:43:06 AM »
Hi Everybody,
I wanted to share my expérience as Dink Street 300i owner with some modifications.
First excuse my english as I'm French (From New Caledonia).
Then I installed for my DS 300i the Dr pulley 14g after testing the Malossi Multivar 2000 with 18g and 15g rollers (x6). I have also Malossi contra spring & Malossi clutch springs.
Regarding 14g sliding, they are very good, at least as good as Malossi Multivar with 18g rolling.
The différence with Malossi white contra spring is revs.
I can reach 8000 right after take off, with just a 1/2 second "pause" at 6500. So I get a very good acceleration off the line, improved vivacity and no belt slippage with this. The bad points are...revs also, as spring tend to close longer the rear pulley so you stay longer in low gear ratio and have some difficuties to get high speed. Also cruising revs are higher than yours, with 5500 at 37mph or 6000 at 50mph.
I think, with my tests, that I finally found the best combination for power off the line and WOT from 5K or 6K are quite impressive. Malossi is great too but I have to re test with 17g sliding from Dr Pulley as factory Malossi rolling are crap. It will correspond roughly to 13g sliding on stock variator, i.e very sporty ones.
At the end, I will anyway buy heavier sliding rollers from Dr Pulley to put in Malossi Multivar and get low revs at mid range speed as High reving engine tend to annoy me after some time !!
Probably 21 or 22g (x6). And go back to stock contra spring to give some relief to the belt.
Regards,
Robin
