Freebaggin Posted January 9, 2004 Share Posted January 9, 2004 Yeah looks like the more boost gave it a tad more power. But nevertheless, its more consistant aswell, which is important! It looks like your running a bleeder.. is that true? Turbosmart e-Boost EBC. The fluctuations in the boost curve are more to do with the Microtech MAP sensor reading the natural pressure spikes that occur in the inlet manifolds of engines, these spikes are usually not seen, i.e. smoothed out with boost guages.

Jay95R33 Posted January 9, 2004 Author Share Posted January 9, 2004 So, if I'm thinking correctly, with this simple BOV mod the turbo is operating slightly more effiecently hence the slight increase in boost pressure as it doesn't have to pressurise the 'leak' in the BOV. ??

ix9 Posted January 9, 2004 Share Posted January 9, 2004 IOne question I do have though, some people have mentioned that doing this mod takes away the linear feel of the throttle. Does that mean that everyone that has a after market BOV that plumbs back get's the same results?? I've never used one so I wouldn't know. YES. It sure does. With my aftermarket BOV, on seperate pipe, and I have the stocker blocked off with a plate, it makes boost hit harder! If sometimes changing gears just as you hit boost, it is quite a big thud of the disengaging of my clutch (it's a ceramic one) and I can notice that the car just hit boost "right then" when I changed. If that makes any sense I for one, will be keeping my BOV mod for when I go to the drags Link to comment https://www.sau.com.au/forums/topic/9634-stopping-your-bov-from-leaking-a-how-to/page/3/#findComment-636070 Share on other sites More sharing options...

Black33 Posted January 11, 2004 Share Posted January 11, 2004 i tried this and feels as if boost comes on quiccker - this mod also generally raised my boost Link to comment https://www.sau.com.au/forums/topic/9634-stopping-your-bov-from-leaking-a-how-to/page/3/#findComment-638345 Share on other sites More sharing options...
sweetr33 Posted January 21, 2004 Share Posted January 21, 2004 have any people experienced problems?? I mean going by whats involved there shouldnt be ANY dramas at all. Ive done this mod and really like it. Ive gotten to the stage now where i have forgotten ive even done it.

Bobjones Posted January 21, 2004 Share Posted January 21, 2004 Blocking the hole should in effect make boost come on quicker and hold higher boost. the s15 stock BOV has a hole in the middle of the piston to allow blow by where as the R33 stock bov has that little whole. I would in fact use some loctite just in case, however when installing it back in the surrounding pressure will hold it in place as long as the screw/nail is flat it will seal correctly. I was considering doing a similar thing, however went the whole hog of installing a GFB stealth...

BOOSTD Posted January 21, 2004 Share Posted January 21, 2004 I have done both mods listed here. Screw: positives - different sound, negatives- causes surge at part throttle, reduces boost ramp speed from part throttle to full throttle, actually holds less boost due to more vacuum present on back of BOV piston. Dodge mod: positives- diferent sound, holds up to 30psi due to less pressure difference between both piston sides. negatives- causes slight surge at part throttle and reduces part throttle to full throotle boost up time.

BOOSTD Posted January 21, 2004 Share Posted January 21, 2004 I have tried both mods. The screw mod causes surge at part throttle and increases boost up time from part throttle to full throttle(due to no air being bleed through at part throttle opening). Also actually holds less boost than standard due to more vacuum being present on the back of the BOV piston. The Dodge site mod causes slight surge at part throttle, holds up to 30psi boost due to less pressure difference between both piston sides. Also increases part throttle to full throttle boost up time.

BOOSTD Posted January 21, 2004 Share Posted January 21, 2004 Increasing the size of the bypass hole will cause less vac on the back side of the piston and also enable higher boost to be held. But cause more leakage.... Link to comment https://www.sau.com.au/forums/topic/9634-stopping-your-bov-from-leaking-a-how-to/page/3/#findComment-654137 Share on other sites More sharing options...

Jay95R33 Posted January 22, 2004 Author Share Posted January 22, 2004 http://www.thedodgegarage.com/turbo_bov_mod.html Cool - thanks for that. With the little pipe thing, did you just leave it to vent into the air ?? Do you think it would cause any problems venting into the air, as air would pass out the pipe when the BOV opens. Maybe the small amount of air that it'd be wouldn't cause the problems that the ext venting BOV's cause. I suppose if you got really fussy you could plumb the little pipe thing back into the return pipe for the BOV ?? If I get bored one day I might give it a try.

snake Posted January 22, 2004 Share Posted January 22, 2004 Boostd, in your first post you said the dodge method decreases part throttle to full throttle boost up time, in your second it said increases part throttle to full throttle boost up time, i assume you mean the latter.
