STAGE 2 GTM supercharger BOV OPTIONS

Jayhovah

Have you attempted to clean/lube the TS BOV? (Just thinking out loud, haven't done this on my setup yet... but I have TS BOV's)

Both me and kentomo280z are running the tial qrj bpv on our gtm sc kits with the 1.5psi spring. it flows twice as much air and doesn't flutter like the turbosmart bpv. you just have to remove the old flange and get the tial one welded on. it cost me 30 bucks at local shop.

The qrj comes in a 38mm flange.was trying to find a direct fit without having to rework the pipe with a 50mm. I did see the vids of the tial 50mm swap and it sounded great that's why I was asking about the qrj size.....http://www.jegs.com/p/TiAL-Sport/TiA...39373/10002/-1


I did speak with a very reputable guy at Z1 and he said he seen a lot of guys use a 38mm wastegate with a lighter spring cause it had a larger opening than a 38mm bov

unfortunately the 38mm qrj bpv wont fit the 38mm turbosmart flange supplied with the kit, i initially thought the same, but the design of the lip where the valve sits is different for the tial and wont seal properly.

i wouldnt recommend a bov like the tial q series because there is no way filter the air as its being sucked into the engine under vaccum, this could lead to dirt and debris being sucked into the intercooler pipe.

Well that sucks about the flanges ...and the bov is blowing air out while at idle with the super charger don't think there is anything getting sucked in.

I have cleaned and lube it dozen of times at first it worked for a month or two before acting up now there isn't any change in it. I think the brass piston may be worn down and slightly binding in movemen.

Right on.. that stinks.

Curious about a couple of things:
1) How old is it? how many miles?
2) Did you contact TS and if so, did they give any options?

I probably have the same valves so just looking for data...

I have been running the kit for just under 2 years about 30k miles
Called turbosmart.not much help they warranty is 1year ....not much they could do since the piston and housing are matched together so replacing the piston wasn't recommended
