Hey hows it going, so Im just about finished with my gt42 setup but my builder is telling my I need to get a better blow off valve so I was wondering if anybody had some advice on what I should purchase. He told me to purchase a tial blow off valve but what I want is some advice on what model I should buy or if that is a correct brand that I should be using? If not can someone please give me some info for the best bang for your buck. And last I need to see if anybody on here can give me the part number to a 3 bar gm map sensor so I can order this through gm please? Thanks guys.

 

I'm using a Synapse BoV. Very happy with it.
Tial seems to be a popular favorite...

What BoV do you currently have?

 

he is probably telling you to get a bigger one due to increased air flow. depending on how much boost you are running the synapse may not be large enough. Tial should do the trick, or you could do like myself and just add a second. im running an S475 with 2 greddy RS's and no surge issues. good luck!!

 

I'm running a knock off tial 50 mm that I got for free. It works great too, 2 years now never leaks no surging. Would never guess it wasn't the real deal.

 

Yeah dregg100 thats exactly what he said, yeah im running a greddy type s bov and he said it would not support the amount of horsepower I would be running, but yes a tial may do the trick any info on a specific model? Or will any tial 50mm work? also any info on the part number on a 3 bar gm map sensor?

 

the new Q valve apparently flows like 60% more than the original TiAl 50mm, and the original was a good unit. I would definitely suggest it.

 

Thanks I will definetly look into that thanks for the info.
