540 vs 640 October 06, 2019 09:16AM
Just wondering how the 640s are holding up with the 4.1 chargers as compared to the 540 light pro's with unlimited intake turbos? Also what is the power difference? Thanks Dave

Both hold up fine, the 540’s make more power 640’s have the torque

From what I've seen of the NTPA light pro class especially the top tier tractors. They seem to have their share of issues. I just didnt know if anyone with first hand experiences with the 4.1s were having reliability issues as well. I'm guessing not as bad since they were considerably less hp at least from what I hear don't really know any 4.1 guys to get an honest answer, however didnt really know.
Thanks Dave.

Apparently no one cares to share any information. That's ok. I'll just have to figure it out on my own. Thanks anyway.
We all wonder why this sport is not growing. I just dont understand this mentality when I know there are actually people with this knowledge have read this post. I wasn't asking anyone for Team Secrets or what's in your engine. Anyway have a great day. We'll see ya on the track when we get it all sorted out some day. Best wishes.

"Just wondering", I believe your assessment of the Light Pro Stock is correct. I do see several Lim Pro in competition amongst themselves and in conjunction with the Light PS's. I do know several pullers in each class. My observation is there is much better performance reliability with the Limited PS.
Good luck with your future pulling endeavor.
