929 rwhp true street vert

[1NA RUN]

Strapped the vert on the dyno today after some minor upgrades and was baffled because it lost power. After about 2 hours of trying different things, we decided to disconnect the exhaust behind the down pipe. Turns out my single 4" muffler was creating too much back pressure. It instantly picked up 102rwhp from the previous pull. We were extremely surprised at the result. Next pull went up 2 more pounds and ended up with a comfortable 929rwhp at only 20.36lbs of boost. This is with a precision 88mm. Obviously has more in it, but that will do for now. Problem is, now I only have a couple of days to figure out how to add mufflers for NMRA true street without the excessive back pressure. Any suggestions would help. Thanks

Cut muffler in half(top/buttom way), 100% gut the inside, and weld it back up. 0 back pressure now! :coolman:

Congratulation on finding out where the power loss was. Your vert must be an absolute hoot to drive on the street with that much power. :burnout: :rockon:

It is a lot of fun on the street although I keep it at 15lbs and have only gotten into it a couple of times.

Thanks for the compliments guys.

try the moroso spiral flow mufflers or maybe even the borla XR1's?

Are you allowed cutouts or some kind of butterfly setup in true street?

Wow. Congrats Raul

Hooker has some kind of muffler that's supposed to flow BETTER than an equivalent diameter pipe. Look into it.

Any more pics or info on the setup? Sounds wicked!

dual 3.5" mufflers. anything straight thru will be best. no chambered mufflers.
