R1 5VY velocity stack lengths??

MK9R - 26/1/11 at 09:40 AM

I'm turning the airbox around, which means adding a spacer, which inturn alters the velocity stack lengths, now i can modify the existing standard stacks to make them the same length even with the spacer (36mm), but from reading around there can be some decent gains achieved by fitting a set of Graves or factory pro stacks which have 2 shorter and 2 longer stacks. These aren't cheap and obviously wont work with the spacer anyway, so was wondering if anyone knew the length of these stacks so i can modify my existing ones, or have any theory/advice.

I have found this site to contain some interesting information on velocity stacks.

yup thats what i been looking at, touble is have you seen the price of them! Plus they will be 15mm longer with my spacer. If i could get the lengths of these and modify the existing ones it would be a good start
