In a nut shell our final finish on this product isn't as smooth at it seems. Is very close to a 120 grit. On the flow bench the x-buffed finish and blasted 120 grit Aluminum Oxide finsh flow identically all day long. Where the differences come into play is if there is anything introduced into the intake charge before the injectors, say meth injection, NOS ect. You want to keep those products atomized and evenly distributed across the intake charge. -Matt Porting & Coating Manager
i picked up 12 whp on the high end in my EWG stock turbo'd sti with TGV deletes... awesome bang for your buck
whats funny is how long this time lapse is... gives you an idea of how much work really is involved in doing a set of TGV's... if they posted a video of this guy porting an exhaust manifold it would probably be at least a 10 minute time lapse just due to all of the time involved in porting
You guys do all that work to make it look so good but, Why would you just tap and plug it when it looks better to weld all of the holes. That is what I would like to see. It would put the finishing touch on them,
i own a subaru and have heard my subie buddies say tgv delets before but never understood what they were really talkin about , thanks for sharing this video !
dude you guys do amazing work! I have most of your bolt ons installed on my 05' STi! LOVE them! I am totally looking forward to getting some port work done this spring once the weather warms up a bit!
Awe man I wish I could tell ya but that is part of the trade secret and our porting guys who have been doing this for years would be absolutely irrate if I gave their secrets away! But, I can tell you that 90% of the work is not in the bits as much as the skill, they could do this with a file and a saw blade if thats all they had haha!
Best of luck on your project though, just remember that you need baby steps, cause if you go a hair too big the whole project is toast.
Hi, Great work :D, What cutters and sanding bits did you use? being from the UK means it will be to expensive to buy the tgv's from grimmspeed so i would like to have a go myself.
@smoovemike Dude, they're not that expensive, especially since you're rolling GBPs. They will find you some cheap shipping, just buy them ... send yours back by ship, cheaper ... they don't care.
Would also love to see a video of the intake Manifold! I just ordered a Makita 906H to do my TGVs with and want to try the intake and throttle body too! Thanks a lot for the video!

Would i have to get a tune after this? Seems like a HUGE air flow difference. Other than that keep up the good work, yall are awesome!!
