Velocity stacks and +4 Degree Advancer
 

Hi Guys, Anyone know the best place to get some velocity stacks and a 4 degree ignition advancer from, Tried Hpower for the stacks and are not doing them anymore and tried Factor Pro for the advancer and they only have +2 degree left, Thanks

Used on both I think are your only options..that and the 4deg advancer is said to only be beneficial to the very early year VTR's

Hi, It's a 2000 model Storm anyone tried a +2 degree ignition advancer as they are available from Factory Pro

A gentleman in Australia (Bill, at PowerH) was willing to build some velocity stacks (alum.) But you'd need a commitment from others to flesh-out an order as he has to do multiples to make it cost-effective. I decided I don't have time/money to devote to it. As I recall the cost per set was approaching three-hundred bucks...

I've got a +4 advancer and twin shorter velocity stacks on my 2000 and it runs very well. I'm at 5200 feet in altitude.

How do you know? I cant see any difference in 98 VTRs and Facelift 1 from 2001 (with 2 x analog + digital fuel gauge) regarding ignition rotor. They are both the same.

I've never seen evidence of any timing changes across model years.

Yes, but it could never been verified whether its the same or not.

Then, why are we talking about it?

If only very early models benefit from that +4 rotor then later models realise that probbably via further advanced ignition values. I need that info in order to clone an OEM ignition map via Ignitech ignition Box.
