anyone here using the freddy intake manifold on there cars… hows is it anyways?
would be better than stock on rb25’s especially because it shortens fmic piping
but still doubt it performs as good as a real greddy but if you can get it for cheap i would hop on it
i run freddy on my SR…
two issues…
the fitment is fine, but i suspect the runners are shorter because there is not enough clearance to run a nismo FPR on my fuel rail… adjuster screw hit the valve cover.
thats a minor concern, stock FPR works fine.
Big issue is the fittings, they are worse than garbage… i’d rather stab myself in the face with hot rusty knife than try and make the china-fittings work. the fittings at the back of the SR manifolds need to pivot so that you can screw them in and still have the nipple facing up for the vaccuum lines… there is supposed to be an O-ring in there or something but on my old Freddy the fittings were total ass.
on my newer one i only got one of the proper fittings, it is decent, better than the others, but i had to reuse one of them.
still… i ran 325whp at 15.5psi with the manifold and the bad fittings.
some people say they leak through the casting in the manifolds. If someone tells you that, never ever take their advice again… ever… they hate you.
Its better for the ic piping by far (why I bought it) but you lose bottom end torque.
o yea and its for the sr20det s13
I’m assuming this is the Topspeed?
I’ve seen one and ran on a car. It fit fine, but the casting looks terrible, especially on the runners.
It did make power, but I can guarantee that the real GReddy will make more power.
unless you could polish the rough casting on the inside as well as chip out all the slag to make it as efficient as a greddy one then I would say pass on the replicas as they are cheap for a reason. An aftermarket intake manifold should be efficient with larger runner and bladder that divides evenly among all cylinders and if it was not designed with that in mind and just a copy then I can see if being an early demise of one or more of your cylinders.
