STV ModVP - Mercury 2.5 Outboard Custom Pipes Test

[@TroyPrewitt-fm7ic]

Gets on the move quick !

[@Chadwicky69]

It doesn't actually......it isn't responding to more fuel on the hit as well as I thought it would and taking fuel away doesn't work either. I ran a median amount on the hit and that didn't work for shit as well...starting to think that I will never be able to tune the launch as well as I thought I could with these pipes. Still a blast to drive and it PISSES EVERYONE off, so that's a bonus!

@@Chadwicky69 it may be better with running through the exhaust tuner , nice boat !

[@TroyPrewitt-fm7ic]

Definitely loud though !

@@TroyPrewitt-fm7ic I know it would be better through the mid but this was a fun experiment with these pipes and I am trying to make them work with my custom fuel curves as best as possible. I changed my intake on this video from the previous video I posted and it picked up power "basically" throughout the rev range but haven't had the time to clean up the launch acceleration......I will get it to the best it can be, although that may still suck haha!

@@Chadwicky69 definitely a cool experiment for sure , I remember some of the old Chryslers & inline mercs used to run those, STACKERS , really cool ! I hope it works out well for you .

How does it trim so fast? What system do you use for that?

[@Chadwicky69]

A custom made clamp bracket with a horizontal trim ram.... That with a Merc trim pump, that I customize for different pressure limits, and then run it on a 24 volt UP and 12 volt DOWN wiring setup.
