Let customers speak for us
ran on a stock fuel 6.7 ripped way harder then previous dbb s400 units highly recommend
Upgraded from a box stock S463 to this unit on my 6.7 Cummins and picked up a ton of power and completely wiped out any smoke on my top tune!
The specific aluminum and fit and finish is one of the best. Shipped quickly and arrived quickly. The round cut oring is much better than the square as well. Very happy with product. The 100mm -10 and -12 for mid and large frame turbos (2 inch bolt space) I wish used round cut orings
exit flange is different than tial also the angle of the exit had to remake wastegate downpipe. but no big deal. nice built and gate opened with in 2 lbs of spring rating.
Great service. Great support. Turbo whistles sweet sweet music.
I keep coming back to BSI for clamp and flange kits, They are about the best clamps and flanges on the market for an awesome price. Highly recommended!!
Worker great
These flange kits fit perfectly and the clamp is very durable!! The flip style T-bolt quick release is awesome as well. I use them for a disconnect on the downpipe for compound kits, makes it very nice for removing the downpipe to work under the hood.
This drain works as it should. I do however see an issue with the bolt hole size could be drill closer to the bolt size being used. This would aid in centering the o ring on a turbo with a narrower mating surface. I was able to smget it centered. Its a great product. For a 8 mm bolt the hole needs to be drilled for an 8 mm hole. The 10mm hole gives too much movement when centering. still 5 stars on the product
Purchased an 85mm turbo for my truck after burning up two vs racing turbos in a 2 week span.
This turbo has taken a shit kicking and works incredible. Just made 855 whp on my little 5.3.
Nick was also amazing to deal with. In stock, ready to pickup. Even went through my old turbo for me on his own time. Will always have my business 👍
Fits perfect! Allowed for a nice large return line that’s leak free!
