SR Viper Yamaha/MPI Turbo Upgrades

[Joe ltx-le]

This is awsome. I'm gonna stick with the mpi equipment this year when I get my sled, but next year I can see the new intake coming.

10 lbs of boost with the .066" thick gasket is 220-225 hp.

12 lbs of boost with the .092" thick gasket is 240-245 hp.

Bottom end really doesn't seem to suffer, it may slightly, but traction on snow isn't 100%, so it isn't really noticable, it is still very responsive when clutched properly. Maybe @Yamadog will tell you how his low end is with lower compression.

Are these numbers running pump gas at sea level? Or what elevation are these running at?

Pump gas sea level, yes.

I will verify there is no lag as long as you have a quick spool waste gate. When drag racing hit the go button and boost is right there you will leave much higher hp cats from the line cause they cannot build boost or torque as fast as this motor.

Pump gas sea level, yes.
