For use on LSA (or similar design) blower setups with any big cam that doesnt pull at least 16" of vacuum at idle. This will fix surge issues with the bypass closing at idle and part throttle. Our modified bypass starts to open at 4" and fully open by 7" of vacuum. We need a core bypass sent in, new bypasses are cost prohibitive to make this anywhere close to budget friendly if we were always using a new bypass to modify. Can anodize any color or powdercoat black at additional cost. These are a modified version of the ones that I used to make for Jokerz. We can also modify any other blower bypass if needed but contact us if its anything other than a factory LSA bypass. Price is does not include shipping bypass in for core modification. All cores are tested before work begins on them. We can also do this with a NEW bypass from Eaton as well, but the price is higher since the $145 plus shipping will have to be added.
