L33 Posted May 27, 2008 Share Posted May 27, 2008 my current dump valve is attached to my intercooler hard pipe, im having a new fmic fitted this week, and ive ordered a hks ssqv, so until it arrives there isnt going to be a dump valve. is this a bad move to drive like it or is it ok? its a stock engine so not running extra boost!

mikeyb10supra Posted May 27, 2008 Share Posted May 27, 2008 do you still have the stock recirc in place?? Quote Link to comment Share on other sites More sharing options...
L33 Posted May 27, 2008 Author Share Posted May 27, 2008 the little black round ish thing? yea thats there, thats what the hks ssqv replaces? Quote Link to comment Share on other sites More sharing options...
mikeyb10supra Posted May 27, 2008 Share Posted May 27, 2008 the little black round ish thing? yea thats there, thats what the hks ssqv replaces? ok so basically your taking the BOV off your old intercooler before your new one is fitted, it this correct?? So its going to leave a big hole in the system if im understanding correctly? why are you taking it off before? why not leave it and change the whole lot at the same time Quote Link to comment Share on other sites More sharing options...
L33 Posted May 27, 2008 Author Share Posted May 27, 2008 not quite. my current dump valve is attached to the hard pipe, which is going to be replaced this week cuz im having a hole new fmic kit, so all new hard pipes so there wil not be any holes! because i dont have the hks ssqv yet i cannot fit it. im not attaching the hks to the hard pipe this time, i wil be replacing that black thing Quote Link to comment Share on other sites More sharing options...
edge Posted May 27, 2008 Share Posted May 27, 2008 What hard pipe is it on? any pics? Someone should have an old stock one for you to use in the mean time. Maybe worth giving jody a call as he might have some knocking about. Quote Link to comment Share on other sites More sharing options...
Daston Posted May 27, 2008 Share Posted May 27, 2008 Is your stock bov removed? Because if you just have a bov on your hardpipe chances are you still have the stock bov Quote Link to comment Share on other sites More sharing options...

L33 Posted May 27, 2008 Author Share Posted May 27, 2008 if u mean the little black round ish thing on the left side of the engine yea thats stil there. my current dump valve is on the IC pipe coming up near the battery Quote Link to comment Share on other sites More sharing options...
Daston Posted May 27, 2008 Share Posted May 27, 2008 if u mean the little black round ish thing on the left side of the engine yea thats stil there. my current dump valve is on the IC pipe coming up near the battery yeah the little black round thing is the stock bov so you will be fine if you fit the hard pipes as that should stop your turbos stalling. Just dont go crazy with the boost Quote Link to comment Share on other sites More sharing options...
mikeyb10supra Posted May 27, 2008 Share Posted May 27, 2008 yeah the little black round thing is the stock bov so you will be fine if you fit the hard pipes as that should stop your turbos stalling. Just dont go crazy with the boost boost shouldn't be an issue, its set to actuate at 0.9bar so should be fine as it will bleed off extra and open early and for the record CW always says if it was HIS car he would do away with a BOV all together. Cant see how this can be good but Chris is a knowlegable guy Quote Link to comment Share on other sites More sharing options...
L33 Posted May 27, 2008 Author Share Posted May 27, 2008 i thought thats what the black thing was but wasnt sure! im not increasing the boost! nic said the hks ssqv should be here in about 2 weeks so i can fit it then. after all that its going to have the whifbitz 400bhp package, so then i wil be increasing the boost but the fmic and new hks wil be fitted by then. was just checking the car wil be ok just running on the standard bov, like i said apart from fmic the engine is stock Quote Link to comment Share on other sites More sharing options...

I only removed mine as it was leaking Quote Link to comment Share on other sites More sharing options...
L33 Posted May 27, 2008 Author Share Posted May 27, 2008 nope! im stock at the mo! should of explained that first sorry! i wil be removing the standard bov when the hks turns up Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted May 27, 2008 Share Posted May 27, 2008 I never run a BOV on any of my own turbo engines, and you will be fine running without one either long or short term. I will be amazed if you feel any difference in spool up time without one, too. Quote Link to comment Share on other sites More sharing options...
ADL Mark Posted May 28, 2008 Share Posted May 28, 2008 Not even a recirc Chris? So in your opinion they are more a marketing gimmic than actual useful device? Why do manufacturer's like Toyota go to the trouble of fitting a recirc if that's the case? Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted May 28, 2008 Share Posted May 28, 2008 I posted in depth a while ago on this, will try and find it tomorrow, they are fitted for noise control purposes, not faster spool. Quote Link to comment Share on other sites More sharing options...
ADL Mark Posted May 28, 2008 Share Posted May 28, 2008 Oh, I thought it was more damage to the impeller fins on off-throttle. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted May 28, 2008 Share Posted May 28, 2008 I was led to believe this years ago, but Geoff Kershaw at Turbo Dynamics, Ken Brittain at Brodie Brittain Racing and Turbo Dynamics (making the three best rated turbo expertise people and companies I know) would seem to concur that the reason for recirculation valves was for noise abatement, not better spool. In the eighties, when F1 devoted millions to turbo development, did any F1 cars have recirculation valves? Do Indy cars with turbos until very recently have recircualtion valves? Wouldn't they if there was the slightest advantage? For sure, wouldn't turbo engined Le Mans cars use them, where longevity was a major criterion?

Zofix Posted June 11, 2008 Share Posted June 11, 2008 Sorry to hijack your thread, but do anybody know if it is possible to run stock BOV and and HKS ssqv(vent in the air) on a UK/US with MAF. Without having stalling og running rich problems? Quote Link to comment Share on other sites More sharing options...
