Here's a picture of the pulley setup:  |
Looking good. There seems to be no belt dust. Check if there is leak from the intake pipes, silicone hoses, gaskets, and/or valve. I'm always interested in the design and actual performance of the E370, especially its 2-1 Y section where there seems to be only one single 3-3.25" pipe as the merge collector. I think it does help advance the scavenging effect but dunno if this will cause back pressure to hinder CFM of big power. From their web info, it seems the exhaust is capable of supporting 700-hp output. Let us know the dyno results and type of fuel you use when you have them (if possible). Guess this is the only way to justify the hypothesis of the restriction (whether it does flow freely or not).
