I will be playing around with this in the future, well, because I can. A cheap deal off ebay bought a new upper grille on to which somebody installed a re-pop R badge. Not worried about extra hood lift due to any additional under hood pressure on the intake tract because I'll have have some aerocatch hood pins.

Also installing the FP front tow hook. Since I have to cut it up for that, why not do this.

BTW, I bought a spare, used (cheap!) GT350 hood as well, so few original parts will be sacrificed for this.

Now I just have to find time to do this.

Just now getting back to this. Plus, it's been too hot in Texas for this stuff... I've been waiting for my dealer to get the kit to repair the rear bumper cover gap. They did that work this week.

Aligning the hood with the GT4 vent and cutting the holes for the hood latches now. If that goes well, I'll pull the front bumper off and do the grill and tow hook install.

What you can't tell until you take the grill off is that the air intake is partially open to to the center radiator opening. I blocked that part off.

In reality this may not do much, but can't hurt.

I believe that opening into the CAI is going to cause you even more hood lift.

Not with hood pins...

I also have another air filter assembly that I may modify the top to put on a separate lexan lid. I need to ask Treynor for a picture of his GT4 to see how Multimatic did his one off setup. I would only require that if I added the two side GT4 hood vents, as they uncover the air cleaner. But since I haven't won the lottery, there will probably not be any more GT4 parts in my future.

Not a problem. It's a good point to bring up for others without hood pins. I thought about this as I wasn't sure I would add pins when I did the hood vent mod.

If it did cause problems, that would mean the modification actually served a purpose!

It's a standard GT350 hood with GT4 vent added. There's a few pictures in the general forum, "What have you done to your S550....today"

This is how I did my GT350 CAI with lexan.

By plate, if you mean the air filter cover then that is jeffv8's mod.

If you mean the hole for the vent, I just had to sneak up on it. The vent only fits in one spot as it follows the lip of the center ridges of the hood. I used an over sized Dremel tool with about a 2" cut off wheel.

The GT4 vent came via Kohr Motorsports from Multimatic. It's not something they have in stock typically. The FP350S vent will probably be more cost effective whenever it becomes available, but the GT4 vents looks better in my biased opinion. However, the GT4 piece is expensive. A new GT500 hood might also be a better way to go, but who knows when that thing will appear.
