Fargo Posted June 1, 2007 Share Posted June 1, 2007 guys, got a questions Re hybrids. i assume when one gets jspec turbos refitted with hybrids that the blades are uprated to steel, then i also assume that this will mean the boost pressure can be upped slightly, What pressue could you up to (safe) Would this increase be ok with standard BPU.

Pixelfill Posted June 1, 2007 Share Posted June 1, 2007 Just remember if you up the boost make sure the fuelling can support it. Uprated fuel pump at the very least, probably larger injectors and a piggyback fuel computer correctly mapped. Or just stick at normal boost Mike Quote Link to comment Share on other sites More sharing options...
grahamc Posted June 1, 2007 Share Posted June 1, 2007 mines mapped to 1.4bar... but I have fuelling and ecu as well... Quote Link to comment Share on other sites More sharing options...
Matt H Posted June 1, 2007 Share Posted June 1, 2007 1.4 bar is fine but i'll tell you from first hand experiance that you need to sort out fueling, bigger injectors and fuel pump with something to alter the fueling map such as a Emanage unit if you want to run the bigger boost I was running 1.4 bar with hybrids when i melted a piston! be warned! its not as simple as just upping the boost Quote Link to comment Share on other sites More sharing options...
grahamc Posted June 1, 2007 Share Posted June 1, 2007 btw - I wont run 1.4bar for daily driving... daily driving will be down aroun .9bar Quote Link to comment Share on other sites More sharing options...
Fargo Posted June 1, 2007 Author Share Posted June 1, 2007 ive got a walbro pump fitted (BPU etc), yep running lean is on my mind so will look at fueling etc, just posing the Q as i MAY have to replace my stock jpecs you see. Quote Link to comment Share on other sites More sharing options...

Marco Posted June 2, 2007 Share Posted June 2, 2007 My brother went up to 1.4bar I think with hybrids. That would be me I'm running 1.3 bar. I've got a uprated fuel pump, 550cc injectors and apexi s-afc2. Quote Link to comment Share on other sites More sharing options...
mikeyb10supra Posted June 2, 2007 Share Posted June 2, 2007 Would this increase be ok with standard BPU. not sure if anyone has answered this yet, but the answer is no, unless your using stock UK turbos and some cleverly placed water/meth nozzels, the J-specs wont withdtand this much boost the turbine will be outside efficiency range and generate a hell of a lot of heat not to mention playing roulette with the ceramic impeller blades on a daily basis hybrids as has already been said can withstand more pressure Quote Link to comment Share on other sites More sharing options...
Fargo Posted June 2, 2007 Author Share Posted June 2, 2007 yes i meant would the increase that hybrids can offer be ok with standard BPU. Quote Link to comment Share on other sites More sharing options...
