There are a few things from a performance stand point that kind of bugs me.
The majority of the intake appears to be a "silicon/rubber/synthetic" tube, will it collapse upon itself under extremely hard acceleration? Maybe, maybe not.
Also, there is a bend before the throttle body. Bends create turbulence, and you'll also notice the placement of the MAF. It is before the bend.
In order to have the proper balance between the airfuel mixture, the air velocity must remain constant.
The question is: is the velocity being maintained from the point it is read at the MAF, to where it is at the throttle body? Especially through and at the completion of the bend?
