GT-R R35 Plenum Test Fitment on my VQ37HR

No Sir, thank you!

It is icing on the top. I've shared this with my club and a couple other Nissan sites. Interest is there especially since it's not "just pipes" and damn near OEM! I can say about 10-15people I know would go in on something like this if it's not too much from my suggested number aka groupbuy scenario! That's just 07/08 folks!

Nice!

I think depending on price, on the amount of spare GTR manifolds laying around, and the amount of Z's with boost in their future, this has a lot of potential to sell well if you beat competition to market.

Will wait to see if there is a group buy pricing. 4 digits, I just don't think I can swallow that lol.

Group buy!?!? God damnit... There's goes the last of my fun money for the year...

If you can managed to maintain the 20-30ft-lb at 5 to 6K RPM after the tune I'm in!

interested - awaiting details following tune

Given we have pretty good data now on M370-vs-Stock, it won't be all that hard to compare the new data to the M370 even if the mfg doesn't have an M370 to play with. Based on his preliminary results, I suspect this is going to be a pretty decent intake setup. My main concern at this point is the strut bar stuff. I don't see how you fit a strut bar over that thing, and I'd rather give up these intake gains that give up that strut bar's stiffness (I'm sure most others would make the opposite tradeoff, though, so I'm sure the product will sell).

This is where I stand too. The car comes with a nice triangulated bar from the factory. I don't want to lose that. I'm sure he'll address this issue. It can't be harder than the work he's done so far.

Yeah, the strut bar is my concren too.

I'm in FTW

Keep us posted when this starts going to production and if you can do a complete write up for install and post it in DIY section.

I'll definately be getting this.

For the strut bar issue, I am curious if something like this can work well.

Was thinking keep the rear part of the triangular bar, cut off the center piece and use a bar like this to wrap around the front. Don't see why there wouldn't be room in front of the manifold for something like this.

As for strength compared to what we currently have, I won't even begin to guess. Most engineering I have ever done is on a phone app.

Room to do it this way would not be my concern. A U-shaped bar like that would not be as stiff as the stock 370z brace which runs straight across. That big U is much more flexible out of plane than a straight across brace. You give up more mechanical advantage by not going straight across and would signifficantly reduce the out of plane stiffness unless you increased the thickness of the new brace enough to add back enough flexural and torsional rigidity which is just more weight and less efficient.

yesterday I started the work on the strut bar issue. First of all we cut the horizontal connection as this will definitely never fit due to height.

The connection between strut tower and firewall is a no brainer - nothing changed there. Now we have to weld something strong enough to compensate for the missing direct link which runs in front of the plenum.

here is the link how it looks currently:

apart from that I have now driven about 2,000 miles with the new setup without any issues - no CEL, no bad behaviour, no idling issues, no nothing. From the current point of view you can simply change your stock plastic intake manifold to the GTR manifold and will have no issues, worries or need for ECU tuning.

Of course, ECU tuning is highly recommended to take full advantage of the new setup but I think its good news you can install it in your garage, drive the car when you need it daily and do the math whenever you have time to and drive the car to your tuner without worries.
