So, I currently do not run a bov of any kind.
My setup, RB20, hypergear op6 highflow, usual supporting mods. Nistune.
240rwkw. With a fair smack of lag, lol.
In past non-bov equiped cars, i've had the zu tututu/ compressor chop/ dose noise. When fitted with a bov, obviously the noise goes away, but difference in performance, or boost drop off between gears felt negligible. (as what most things I've read/searched)
Current setup however, feels a bit different.
If I get it on boost (>12psi) then lift to change gears, I dont tend to get the compressor chop, just one big choof, almost like an atmo bov. Also notice a fair drop off between gears.
So afaik, the 'dose' noise is intake air coming out though the turbo, afm, etc slowing the turbo down (but not completely stopping it)
One big choof would potentially mean the turbo is stopping?(or slowing down much more)
Also, being a standard size core style turbo, would assume inertia would be rather low, compared to a much larger turbo.
Do you guys, in this instance think a bov would assist in getting it back on boost after a gearchange?
Cheers
