Mad Turbo Werks stage 4

Looking for more info on this turbo! Is anybody running this turbo?

Jame's will be soon, I think he'll be the first to be able to give you real life results. I know the stage 3 runs awesome

I'm running an RCD 68 vgt with 205/100s right now, seeing if it's worth the upgrade.

the rcd charger uses the stock turbine, the stage 3 will be a night and day difference. You can put as big as a compressor wheel you want on the stock turbine and not make more power, and just experience surging. The turbine is where the flow is at.

While I have never ran the RCD turbo, I have to agree with Greg here in thinking that the larger turbine wheel will allow for quite a bit more top end flow. Also the Stage 4 has a larger (more efficient compressor wheel) too. I would be VERY surprised if you didn't see a noticeable gain.

I'm real happy with the 68, just looking for another option for sled pulling to keep up with the 6.4's. http://www.youtube.com/watch?v=mibno-bnH0o&feature=youtube_gdata_player

The real beauty of the Stage 4/3 turbo(s) is that there will be no "visual" difference between the two as they look identical to the casual observer. However the Stage 4 should be good for ~50 psi of boost. I think that'll be some airflow for ya.

I ran the stage 3 on my 04 and it did awesome with my 190/100s so with your larger injectors that thing would be great for pulling without surging

50psi seems like too much boost for a vgt for me. If your really wanting big power switch to a fixed turbo. I snapped the shaft on my cheetah and switched to a s300 and I'm never lookin back!

There is a Huge difference between a gt37 series shaft and a gt40 or gt42, so its not really a good comparison.

True. But I really wasn't tryin to get at that. I've always been under the impression that vgts were made to operate efficiently at 30-40 psi. Aren't you driving em to hard when u push them past the point?

if i'm not mistaken....Adrian might have upgraded the shaft on his stage 3 and 4

seems to run pretty strong...what size injectors you got?

pressure ratio of a gt40 series turbine and compressor have a far different pressure ratio map compared to anything thats used with a gt37 turbine. The stage 3 and 4 will be far more efficient at 30-50 psi.

Greg is right. A LOT of the known conceptions with respect to "VGT" turbos kind of are out the window with Adrian's Stage 3+ turbos. For lack of a better description, he has kind of left the reservation with these turbos and entered a new frontier with respect to VGT turbo performance and the Ford 6.0. Purdue_stroker, you are absolutely correct with the 30-40 psi range and a GT37 series turbine wheel, but as far as the GT40 series turbine goes, Greg is right with the 30-50 psi range as the turbine simply allows for decently more flow of exhaust gas in comparison to the GT37 series turbine.

Makes sense. I just didn't know much about what all went into the mtw turbos

He gets a.lot more involved with the internals than your off the self powermax.

I wasn't runnin a powermax. It a cheetah from Fleece Performance

6.4's are awesome i wish i had known about this sote when i had my 6.0 they are awesome! I loved the power and the smoothness of them! Glad to see you guys pushing them really well!
