Granted the machine work is crap. But the basic port design looks to be right on par.I cant judge the size of the "V" in the pics. Hopefully its not to much bigger than stock.
The ideal is very similar to our before the "hand work" is done. If done correctly it looks like you may stil be able to see some alright gains.
And it looks a little thin under the rotors, that may be a issue..But again it may just be internet pics playing with my eyes.
