That was my thought too. At least cut it back inline with the fangs.

Cut it all out. Cut out the fangs. Make an FRP cover plate for the bottom and veneer it with CF, or paint it to match (or accent, or whatever). 1 day project.

As it stands now, temporarily, maybe.

I'd rock it.

Yeah it actually looks decent, I'm going to monitor my iats, I might do something similar :)

Keep in mind that you need 3X the exit area as intake area for cooling. Air expands as it heats up and the hot air will need someplace to go. That is why the vented hoods work well.

This will help but at some point you will reach max outflow and then making more inlet won't help. Otherwise, nice!

https://uploads.tapatalk-cdn.com/201...55a3e87225.png done tuning on uprev, with added air to air only, same dyno, months apart, 450hp 355 tq. Ty topz for more power! Ecutek should be here next week, then I start data logging with seb and back on the dyno to see what those numbers will be!

My blow off valve is open almost all the time, unless I really am into the throttle. Lite cruising it's fluttering, once it hits 3500+ it's really dumping out when I'm in the throttle and climbing in rpm, like anything less than 80% throttle input it is wide open, any thoughts? Test pipes and 9 lb pulley so I'm not running as much boost as most, should my spring be stronger than the 1.5? Seems to run fine other than jerking on the highway because the valve keeps fluttering

well mr king of bikes, I have a tial QRJ on mine and it is quiet as soon as you press the gas pedal from idle (while in gear). Let off the throttle and it dumps immediately very loudly and gets quieter as the RPM lowers as you would expect. I get very light fluttering while cruising around 2k to 3k rpm, not accelerating or decelerating.... doesn't effect driveability, just something you can barely hear with the windows down. I can't remember the spring on mine, I just bought what TopGunZ told me to get. I am no expert but if your boost is exhausting while in throttle I would think your spring is too strong and is requiring more boost pressure at lower RPM to shut. Or something is installed wrong. Maybe let the guys know what BPV / BOV your using and someone could shed some light on it.

Mine is stock pulley.... so only 8 lbs of boost too

Sweet. Before you go ecutek and pay for a tune, get the si trim. Make 30 more whp and tq. For $400. Dollar per hp is a no brainer!

Hello all. Not sure if this thread is still open, but I just received my TopgunZ kit and was wondering if anyone had any install vids or pics. I've only seen one video on YouTube and that was just a startup with the kit. Thanks

There are also a few "Install" threads in the "Forced Induction" category that you can peruse for more build advice/photos.

Turtle64b thanks.

Going to upgrade impeller... anyone have any recommendations on where I should purchase it? Or if I should send it in?
