GT-R R35 Plenum Test Fitment on my VQ37HR

Alstann

I'm really interested to see what the balancing tube does for our cars...for the 300ZX guys, they experimented with tuning the balance tube, and it changed the power curve characteristics and whatnot. I know the HKS supercharger intake manifold has a balance tube as well.

I think that combined with the smooth, individual runners will net some serious gains, especially on a tuned, boosted 370z. I forsee it as a higher displacement version of the VG motor, in a sense.

hey folks, back from Egypt and already made some extensive daily driving with the new setup ! So far absolutely no problems:
- cold/warm startup
- idle
- throttle response
- no CEL codes
- fuel economy
- WOT from 2nd to 6th gear

to sum it up the car acts, reacts and sounds completely as stock.

I cannot say yet if there is more power or torque even though it really feels like it goes through the gears faster as before but that could just be my imagination

the dyno* is booked for tomorrow and then there will be proof - stay tuned !

Chris

* same dyno I made two "before" runs with 6 weeks between each run reaching exactly same curves up to 1HP accuracy !

The two banks are already connected inside the stock manifold, so there is no need for a balance tube.
