Competition Has anyone here tried the II 71?

Yeah Merrick.

 

[Jim Fulmer]

OK, I am confused. Fulmer is running a Super Phat Shaft 66 as his small turbo?



is this correct?

Nope, it's running as a single. The Twins (the piping) is sitting on the bench... . which remind me the shop is still trashed.

After speaking to Brett and Shane, it looks like the Silver Bullet will be my single for now. . The quicker spooling of the 66 when not using nitrous to my understanding is the main reason. .

How comparable is the II 71 to an S400???

The K31, GT42, S400, II 71, and Aurora 5000, are all quite comparable on the compressor side, each having some options. The turbine side is where the main differences are. The GT42 has a ball bearing option on the CHRA.

The GT42 has a ball bearing option on the CHRA.

... and a water cooled CHRA. I'm a big believer in this option for longevity. Having a ball bearing CHRA is the icing on the cake.
