Last set-up, on driver side, had similar intake piping...have no #'s w/ & w/o for comparison though. Easy enough to remove and replace w/ filter or screen for track use.

Lots of debate on this elsewhere as well:

Just rcv'd update from dyno:

IAT after (2) pulls last week w/ filter directly on compressor inlet - 170° (617hp / 542tq)
IAT after (2) pulls today w/ "cold air pipe" - 128° (635hp / 557tq)

oh...and no belt slip


edit: It does appear that ambient temp last Thursday night was 10 - 15° warmer than ambient temp this afternoon...so I'm sure the cooler temp played into this some as well.

 

Gonna re-route the piping post IC to get it out from being directly behind the radiator and fans to further reduce IAT's...then add the pre-compressor methanol and see how she likes it.

 

Has anyone checked for belt dust in the engine compartment? I'm very pumped about the 0 belt slip.

 

Only one I've been able to find so far...
