Don't know haven't dynoed mine yet. Still spools fast and moves a lot of air on the top end. Much more pull in the upper rpm. I'm running a Fleece controller.
is the exhaust brake strong?
which vgt are you using, is the exhaust brake strong?
Modified 351 and yes braking is strong.
They have a handy feature on this site that allows you to browse all threads related to your question. It is so easy to use even a cave man can do it. It is literally as easy as pressing a few buttons.
Maybe you should start with searching for the words "VGT" or "HE351" and read all 50 some pages of info?
I would like to put a 351 on my 24v. Seems like a great upgrade.
Having a bad day? Know the feeling my HX35 just gave out... Made some really neat noises! lol!!! :Cheer:
I've seen all those threads but it's easy to get lost in the endless discussion and most focus on mechanical operation of the vanes. I think a quick "How do you like it" thread such as this hits the spot! The others barely touch on the Fleece controller, from what I've seen. I for one am interested in throwing a VGT on my 24v and go with the Fleece controller but a little more feedback would be great.
Its available! We currently offer them for 98.5-05 Cummins, using Holset chargers.
