tuff New Member 5 Member For: 10y 2m 25d Posted 06/03/15 01:45 AM Share Posted 06/03/15 01:45 AM Hi guys, a quick question for you...What's max hp you think a single impco 425 will support in blowthru config?Got an EGAS ba wagon I'm dropping a turbo fg motor in on straight gas and rather than going full injected vapour lpg, was exploring possibility of going blowthru carby and just tune factory ecu for ignition for boost.Due to the fly by wire my gas research mixer is not happening so figured impco is next best bet.Chasing 350rwkw so probably way out of its league. Any thoughts Link to comment Share on other sites More sharing options...

Economy is alot better than a simple mixer ring as the BLOS is a variable mixer. One is enough for 200hp N/A but im sure it would make more with boost being shoved through it. They are also well suited to turbo applications and wont require any modification. Not sure about the impco but I can see how a traditional mixer ring may not be suited to a boosted application.Dont know much about gas research converter but I know the omvl one I have is only good to about 400hp and its the biggest they make. Any more and I guess you need 2?Also another thought, with the way lpg pricing is going is it all really worth it, im finding im only marginally better off atm, glad I didn't pay for the conversion...Another thing, all systems must be closed loop these days for emissions, and stepper motors are gay, this is where an injection system is much better as most of the time your not in open loop(over 3500rpm...ish), mine feels alot better response wise without the stepper motor as the blos carbies dont need it...bit its not legal(I have taken the piston out od the stepper....shhhh looks legit...)

I'd like vapour injection but at around $3000 for supply and tune, then.me doing all the fitting, it's just ridiculous when I have a gra setup in the garage that is capable of big hp. Any idea who.has the blos.mixers? Never heard of them before. This setup might be a lot easier than I thought Edited 06/03/15 03:28 AM by tuff Link to comment Share on other sites More sharing options...
