Thought i would share my Sidewinder with all of you :)
Its buildt with a BorgWarner EFR turbo that have a super fast spool up and has capasity to deliver
450hp .
We also did make a bigger intercooler and removed it from the nose becouse of we have seen lots of
snow and ice building up in front so the intercooler is not getting any air thru.
Bigger fuel injectors also.
And we took a Apex oiltank and placed it where the stock exhaust muffler is becouse of the
place the Borgwarner turbo is mounted.
supercool thing with that is that the oil from the apex oil tank is oil outlet is now running from the tank into
the engine with same hide and not up like the stock, so when catwalking the engine always have oil :)
And of course its easyer to get of the gearcase :)
We have been using MaptunerX to flash it with higher rev limiter and take of some fuel at lower rpm becouse
of the larger fuel injectors.
But for now we cant raise boost more than 15,6 psi with the flash but they are working with it so i can run about
280-290hp on premium pump gas.
