JWT do hi-rev springs but only for the HR head, not the VHR head .... which was one of my reasons for going with HR heads on my build.

Sticking with VHR equals lots of constraints for a race engine ....

Sticking with a VHR for a road car makes sense because it is cheaper in the long run, BUT is will mean 7500rpm rev-limit (or close to it)

Dammit, this sucks. Only company that makes upgraded springs is GTM.

Wow, im interested. I know jwt is working on a set for the stage 2 cams. Please let me.

I'm interested in this as well. Did some looking a while back and couldn't find anything for the VHR.

Unless I do a group buy they will be right around $650 for a full set of dual spring setup... but if I went with them I would go to a 272 or 280 cam

BBRSpeedWorks · 10-26-2015, 02:40 PM

Which i have also..but we are still testing...problem is we don't have a n/a car to test them on

Lt8Che · 10-26-2015, 03:35 PM

I have the 272 Jun Cams sitting awaiting my final build (but they'll be going on with the BC 4.0 Stroker and some upgraded turbos). Really curious what springs would be out there for my application.
