Its just so subjective I dont think you could really compare builds and results. 839 is nothing to dismiss, though. Congrats.

I’d like to see track times back it

There is a guy out here on a sxe369 cc/sb who put that same charger in the 10s as a single.

That's some impressive power for a S369. I would also like to see track times back it up, as dynos vary quite a bit. I am also curious how it holds up if street driven. I grenaded my S371 (twice) on a ~750 HP tune. Finally got it to live on my current tune that dynoed 660 HP.

Let us know how it runs at the track, and I hope it stays in one piece for you!

Reason I'd never pick an s300, sure they do fine and if done right hold together but imo a 300 frame is too small for a dmax. Just get a 400 frame and be done.

I would have loved to put a 400 on it but I am limited by rules in the class I pull in. Not trying to start a dick pulling contest just wanted to see what some other guys have made on the dyno with an s300.

Curious to hear what sort of class you pull in that limits you to an S300. Most sled pulling rules limit the compressor inducer size rather than frame size or turbine wheel.

We run a small frame 2.5mwe or 2.6SB class with no limit on frame for the 2.6SB

People who probably want to be competitive in a class would find this information useful ;)



It’s really all in good fun for me. This isn’t money making for any of us. It’s not a business for me so if I can help other guys out with goals etc I’m all for it.

Makes sense. You can put the biggest compressor in the 2.6SB cover and only make so much power out of it.

That said, I know 2.6SB top trucks make 1000+ but I don't know what your area is like.

Boy I’d be interested to see what charger they have. If that’s the case I’ll be going that route next year. Everybody who went from a 300 2.5mwe cover to a 2.6SB hated it.

I believe there have been multiple 2.6 chargers over 1000, Barder I think was at least one of them.
