Does the bar have to be on top of the engine bay? Why not under the car?

You want to tie the strut tops together. There's more flex at the top than the bottom since there's a lot more stuff on the underside of the car.

Right, it's a matter of geometry. In many ways the bottom corners are already connected (through the suspension, subframes, crash bar, etc) to each other. The tops, however, can flex around bit as the body twists and rolls. The point of the strut bar is to stiffen the front of the car against that flex/twist.

All things considered though, I don't see how he's going to maintain exactly the stock rigidity with this taller plenum. If it were me, I'd probably go for a compromise between the current hack (remove horizontal bar) and the photo above with the bar angling out to the front. Do a single wide bar like the one in the photo, but angle it around the back tying to the base of the windshield like the small bars do on the stock system. At least then the center of that angled flat bar will be fixated at the center.

yea, so we G's are gonna need a strut bar... I can be your guinea pig, I just need to take the plenum as payment for my G's time... LOL!

What if you cut away some of the support bracing on the underside of the hood, only in the area where a taller strut brace would go.

Would this give enough clearance for a taller brace to fit above the new manifold and still not touch the bonnet? Would it weaken the structural integrity of the hood too much if you removed some of its bracing?

heck cut the hood and let the world see your bar! When they ask why, you say "because GTR"

Too much talk about the strut bar.. Honestly get this thing into production and worry about the bar later.

That bar plays no factor for me in deciding to buy this.

1. This thing is a metal intake and is sexy as phuck. +

2. This thing has proven gains. (More than expected IMO) +

3. This opens up the engine more and tests were only on a N/A app. Imagine TT/SC or Direct Port

I'm ready to pull the trigger. All the talk of strut bar issues or the need for one or fabrication of one can come later.

That should be the next venture after this goes into production and should not be the reason for delay of this.

Lets do this Chris! I'm ready

Good points. There needn't be a straight across bar when a pair of shorter triangulating bars (shock tower to firewall) braces could be fab'd later if at all. Just priced a GTR IM at the dealer here and they want $800.

JC671

Exactly..... Unles auto-xing or drifiting a hardcore bar IMO is not needed. As far as the actual GTR manifold it can be had for less online. The key to all this that Chris has tested and fabbed is the lower plenum.

LOL sorry man That's the old school Sgt in me kicking in. Quit all the non-sense and streamline the end goal lol Lets get this thing rolling.

I would like to see more results to validate the gains. Preferably, on a car that's already tuned with full boltons.

That would be cool but being that this is only a prototype and the guy who is innovating here is not some big company with endless money for R&D.

If he had all the bolt ons and tune people would as for gains with just the intake maniold and nothing else. You have to take what he gained with what he has as the starting point.

He's not fully tuned with it so gains are only gonna get better and he has minimal mods so that's a great gauge of what may come or is possible.


Unless this goes into production no one will know what other gains are to be had unless you get one or fabbed one yourself.

Take what he has done, know that it fits, it works, and do some innovating and be the first with TT with it or SC or in my case Direct Port Nitrous.

I know this manifold will perform and will not be just some engine bling that decreases power.

The work is done thanks to Chris just need this in production
