M8RGT delete blow off valve

Well I can't remember who it was on here suggested that you don't need and maybe don't even want a blow off valve on a m series turbo. I took a thin piece of aluminum and slid it between the charge tube and the BOV and ran the M8 all over at 10 and 12 lbs and i do believe he is correct. I didn't hear or feel any adverse reactions only good stuff like quicker response in and out of the throttle. I don't even miss the paasshh when letting off. Thanks to the gentleman that suggested that.

if you have quicker throttle response with out the BOV AT 10 TO 12 POUNDS then that would lead me to beleive that it wasnt working , A BOV is designed to relieve the pressure or boost from the system and when you chop the slides shut it creates back pressure on the turbo causing the compressor to stall (in which case you would hear compressor surge) and when the compressor stalls momentarly it takes a little longer to build boost again but with a properly working BOV it relieves the pressure and lets the turbo free spin at dang near full RPM until you whack the throttle open again.
Not trying to argue but something just doesnt add up to me on what you are saying.

The theory is that with the blow off valve on lower boost sleds, that the loss of pressure inside the intake makes more lag than the slowing of the turbo.

I have found this to be true. I still use a blow off valve, but have it as tight as it gets.....
When thinking about how much pressure it takes to stall a turbo, it takes quite a bit. When you are getting in and out of the throttle, the throttle almost never closes, so air is still moving in one direction, albeit slower.
So unless you are running big boost....which I would guess in the 15+ range minimum, I would bet you find similar results......it's worth adjusting your blow off valve on the hill and testing to find out!

Theory is all well and good

Theory is all well and good but real life tells the tale. Try it you might like it and it may surprise you.

Yes, but you couldn't tell it by the way I started my reply. Did you read my thank you? I agree with you 100%. Can I blame it on minecat? He got me all screwed up
