Gazbvr6 16 Posted June 26, 2017 Report Share Posted June 26, 2017 That looks fantastic! Fair play to you sirHave you not bothered with a recirc valve? boab3 1 Link to post Share on other sites
boab3 164 Posted June 26, 2017 Author Report Share Posted June 26, 2017 Recirc for keeping turbulence away from maf? Link to post Share on other sites
Gazbvr6 16 Posted June 27, 2017 Report Share Posted June 27, 2017 It recircs air back through charger when throttle is closed mate boab3 1 Link to post Share on other sites
boab3 164 Posted June 27, 2017 Author Report Share Posted June 27, 2017 Ahh a recirculation valve nah i dont.. i believe there not much good for idle issues etc Link to post Share on other sites
Gazbvr6 16 Posted June 27, 2017 Report Share Posted June 27, 2017 See how you get on. I fitted mine when i fitted the charger so I don't know what it's like without. It stops issues on full bore gear changes as the air/boost has nowhere to go when the throttle plate closes. I'm pretty sure all boosted cars have them boab3 1 Link to post Share on other sites
boab3 164 Posted June 28, 2017 Author Report Share Posted June 28, 2017 It recircs air back through charger when throttle is closed mateI might use one ive just read up there a requirement on a supercharged car using a maf.it makes sense at idle the maf can only read the air between maf and throttle body which would be a dead head which inturn can make it run rich as the maf isnt reading a flow.if i fit a recirculating one the maf can then read a flow at idle.Bugger means altering pipework not too hard i suppose.any recommendations for a recirculating type? I can pipe in between outlet and throttle body for valve and pipe from valve to a joint i have at inlet of charger Link to post Share on other sites

Gazbvr6 16 Posted June 28, 2017 Report Share Posted June 28, 2017 Yes vag one preset. Thats why i went for it, plus no piston to get shitted up. 22mm rings a bell but it could be 25 so i may be wrong. I'll try and have look later mate boab3 1 Link to post Share on other sites

boab3 164 Posted July 8, 2017 Author Report Share Posted July 8, 2017 Just need 2 T pieces one to T in before charger one to T in between outlet and throttle body one vacum hose to blend in with colour scheme and 2 hoses from valve outlets to T pieces in red aswell. mk2vrsix 1 Link to post Share on other sites
mk2vrsix 0 Posted April 2, 2018 Report Share Posted April 2, 2018 @boab3 hey dude did you manage to fit the valve up ? How did it run? I have a zr1 set up on my vr but no recirculation valve so was thinking about it ! Link to post Share on other sites

I have a zr1 set up on my vr but no recirculation valve so was thinking about it ! Hi mate ive just literally plumbed it in yesterday just awaiting another silicone hose to connect to bottom of the diverter valve.here's hoping it cures my rich running at idle. I'll keep you posted mk2vrsix 1 Link to post Share on other sites
mk2vrsix 0 Posted April 2, 2018 Report Share Posted April 2, 2018 Brilliant look forward to hearing how it goes Link to post Share on other sites
boab3 164 Posted April 14, 2018 Author Report Share Posted April 14, 2018 (edited) Well plumbed in and running its a bit better but still a bit rich.decided to have a look at valve aghhhh its been uprated to yellow spring thats 15-23psi no way will it open under vacuum with that hefty spring and very little pressure so new green spring on its way from forge thats 5-15psi so hopefully vacuum will open it easily at idle now.it is much better just now but i'll change to a lighter spring and update ASAP Edited April 14, 2018 by boab3 Link to post Share on other sites
boab3 164 Posted April 18, 2018 Author Report Share Posted April 18, 2018 New green spring fitted running much better.now need to relearn ecu since its been powered down so long.good excuse to blip the right foot Link to post Share on other sites
boab3 164 Posted May 24, 2018 Author Report Share Posted May 24, 2018 Ok so was still bit rough on idle really digging deep to source whats going on.checked wires from maf and lambda back to ecu all good.crank sensir slightly below limits so i replaced it but still the same. Next up was dizzy and leads checked then last 2 things I'd forgotten about knock sensors even tho there only a microphone they retard timing by 12 degrees no good to me early spark with big injectors and lots of fuel.well turned out rear knock sensor bolt was loose sensor rattling around and its now not reading anything with multimeter.glad i had a spare new one fitted and running smooth Link to post Share on other sites
boab3 164 Posted May 28, 2018 Author Report Share Posted May 28, 2018 Front knock sensor cracked aswell giving a false reading to ecu retarding ignition so awaiting new sensor. With regards to isv whats folk done with there isv?what happens to this under boost? As ive no t off the outlet of charger to throttle bodybody i was going to t into before charger but after maf so it has a suction of metered air.just i plugged vcds in and throttle angle was sitting at 33 degrees with foot off pedal ive read it should be 14 degrees but as i deleted my isv previously i screwed up the throttle screw to get a fine idle.so now im going back to setting idle angle back to 14 degrees and fit isv to supply my idle just not sure how the isv is plumbed into a charged motor.
