@gimmie11s Probably figured people won’t buy it and make that same mistake twice :rolleyes: . If they kept the same bolt pattern I’m not too sure it would of even been worth it.

That's a good point. I thought there were some great choice already in the original bolt pattern but i can see why they wanted to go bigger.... doesnt matter if the "bigger" units failsafe every time though!

Just saw Alex Flores upload a video with Lund Sr. He swapped his Gen 3 for the 3R and picked up 100 hp just swapping blowers. 2014 GT500, no tune update, same setup on C85, built 5.8 with L&N NSR cams, 11.5:1 compression. 2.4 upper with 15% OD lower.


Very impressive, and about damned time they bail on the proprietary bolt pattern. Im still very curious about IAT2 temps with the small upper and OD lower vs a Whipple 4.0 or 4.5 with stock lower and smaller upper 3.25"

Regardless, this 3R just put the VMP unit back into consideration. For my specific setup though, I have to consider the Whipple big boys. Ill still be at 5.4L displacement and only plan on bumping compression to 9.5:1 (versus the 2011 8.4:1).

That extra 3 points of compression makes a big difference.

Impressive . I wonder if there is less heat soak with this new design
I hope so. I do not question this blower's ability to make power. From the graphs on Sr's pulls, the torque curve looks very healthy. In the video, VMP told Lund that the unit makes a smidge less torque down low but makes up for it with the impressive HP gains up top.

The question for me becomes "How much IAT2 will a 2.4" upper and 15% lower with this Gen 3R generate compared to a stock lower, small pulley on a larger displacement S/C?".

Just look at the boost curve, it tells you all you need to know on 3R case flow and why it make Mo powa!
I’ll either hack up my 3 and try to make the higher flowing 173 TB work or hit the easy button and upgrade to a 3R.

Pump gas problems :)
Love my corn power.
