GT-R R35 Plenum Test Fitment on my VQ37HR

ChrisUR

well, what I can say for sure is that this uprade will help everybody who goes or went FI - for the NA guys (like myself currently) it will be a surprise if and how it improves or not.

All I can say is that you have very little room to play cause the position of the plenum is quite pre-defined by the valve covers, hood, oil cap, etc. - so the way we are building it is plus minus a few 0. inches the only possible solution.

We try to make the piping of the lower manifold as big as possible / as close to the GT-R runner diameter, so with FI you will absolutely see gains because of the higher volume and better flow.

The fuel rail issue I worked on today is really a PITA - we will see later on if keeping the stock rails really is the best solution or if it wouldn't be easier to design new fuel rails which also have a larger diameter - which also would help those with bigger injectors, etc.

But for the prototype I will constuct the adapter to use stock rails, so we can do the first test runs asap.
