you can run more boost.. just need to build it first

Also, different engines and setups. You run that much boost on a VQ3.7L and you will be in the 800HP range which will require a good bit of other upgrades.
Definitely looking forward to results on this EFR setup, going top mount is going to be tough as I think you will run into hood issues though a custom hood would be nice.

Lmao hoods are lame who needs um!

Yeah we will know hopefully soon enough as to what clearance will be like. But oh well what's another mod amongst many at that point haha.

Also guys if we are successful and people are interested er will be up for selling the custom manifolds and piping and hell even a full kit if we get serious.


Also as promised here is part of an email.


Okay well knowing what you are wanting, the 6758s would not be the proper size.* The 6258s would be the right way to go.* Ill elaborate on the turbine wheel issue a little further down.* As for the power, the 6258 would easily make 500whp and would also be able to make up to 900whp.* What we have been seeing from the EFRs as a whole is that the turbo is actually making the "rated HP" to the wheels which means that after the parasitic drivetrain loss, its still able to achieve what its rated at.* The reason is because the turbos design and aero is much more advanced than what we have seen in the past.* In the past we would equate HP with LBS/MIN. so for example the gt3071 is rated at 46-49lbs/min and you would multiply that X 10 and get 460hp.. so the industry standard up until the EFR was 10hp per LB/MIN.* By the time that you installed the gt3071 and dyno'd the car, it would not make any more than 410ish whp depending on the tune and other variables (altitude, comp ratio, etc.) But with the EFR, the 6258 is only rated at 43-44lbs/min yet is making a consistent 450whp on a single turbo setup.* So the standard LB/MIN X 10 is more along the lines of X 12..

2 of the 6258s on the vq will be spot on and you would love the spool times and transient response for sure.
