Yellow Peril 27 Posted May 4, 2015 Report Share Posted May 4, 2015 This came on the car but I want to remove it. Talk me out of it if you can but I don't like the noise. http://www.thelotusforums.com/forums/gallery/image/4134-img-2227/ If anyone want's to buy it from me, please PM me an offer. Questions: 1. Do I just replace the T-piece with a straight through hose - I'm assuming "yes" ? 2. How is the smaller vacuum pipe arrangement altered? This is how it looks now: http://www.thelotusforums.com/forums/gallery/image/4145-bov2/ http://www.thelotusforums.com/forums/gallery/image/4146-bov4/ (apologies if you need to turn your head sideways but when I uploaded the images they got rotated!)

Zolder 11 Posted May 4, 2015 Report Share Posted May 4, 2015 (edited) The black vacuum pipe just needs pluging into where the short red vacuum pipe is fitted currently. Edited May 4, 2015 by Zolder Quote Link to post Share on other sites
Gold FFM Escape 776 Posted May 4, 2015 Gold FFM Report Share Posted May 4, 2015 I can understand very well you don't like the noise. But my current and previous Esprit came with an open BOV, and I wasn't too happy with it either. The first one I could replumb to recirculate via the airfilter, the second one is a different design and will have to be replaced. A BOV does have it's use, but an Esprit doesn't need a whooshing sound to draw attention. ;-) Quote I have made many mistakes in my life. Buying a multiple Lotus is not one of them.

mr.oogieboogie 121 Posted May 4, 2015 Report Share Posted May 4, 2015 Fit a recirculating one. No woosh Quote It's Oogies turn to boogie Link to post Share on other sites

Vulcan Grey 251 Posted May 4, 2015 Report Share Posted May 4, 2015 Agree on the recirculating one. here's a friend's, pipes back into the airbox. Here's the one I'm going to use, haven't plumbed it yet. Quote Travis Vulcan Grey 89SE My Lotus Photo and Projects Album Link to post Share on other sites
Gold FFM Escape 776 Posted May 4, 2015 Gold FFM Report Share Posted May 4, 2015 That's exactly what I did. My first Esprit actually had a recirculating BOV, but it was left open (maybe the German owner liked the whoosh). I connected it to the airfilterbox via the inlet from the crankcase ventilation, and rerouted that to a catchtank and filter. Much better, you could still hear it, but only when paying close attention and pushing hard enough. :-) Quote I have made many mistakes in my life. Buying a multiple Lotus is not one of them.

cammmy 16 Posted May 7, 2015 Report Share Posted May 7, 2015 After doing the ram air mod on mine I wasn't happy with the lack of BOV. You can really hear the surge when the throttle shuts and I'm sure a few of the pops were back through the turbo rather than from the exhaust. Not good. I'd try and find a way to re-circulate it or fit a recirculating one. Quote Link to post Share on other sites
Qavion 19 Posted May 11, 2015 Report Share Posted May 11, 2015 (edited) 1. Do I just replace the T-piece with a straight through hose - I'm assuming "yes" ? I believe there should be a black/white check valve in that line. Make sure it hasn't been removed and replaced with that "T" piece. There is a message thread somewhere on the forum listing the problems people have with blow off valves (adjustments are critical and may do more harm than good).

Yellow Peril 27 Posted May 28, 2015 Author Report Share Posted May 28, 2015 OK, noted Ian. I'll leave it alone for now whilst I investigate my options. Quote Link to post Share on other sites
cammmy 16 Posted May 28, 2015 Report Share Posted May 28, 2015 (edited) Just to note. The HKS SSQV requires no adjustment at all as it works on vacuum. It does need a good vacuum source though. I had to use the MAP sensor port rather than the one for the charcoal canister. You can also get a kit to have it recirculate if you don't want the noise. Our cars may not have had a BOV from factory but personally I think that was a mistake. These aren't a low boost application. Edited May 28, 2015 by cammmy Quote Link to post Share on other sites

Qavion 19 Posted May 30, 2015 Report Share Posted May 30, 2015 Sounds correct... White towards the right side of the car. Quote Link to post Share on other sites
