Nitrous anyone *cough* 200shot? Car would murder if we spray it, but thats not going to be for a while, even a 75progressive shot would be more than enough to my liking.

So to answer your question, nope don't regret and glad to show off new options to the VQ.

Cars are a waste of money either way you go haha.

Oh and I did edit the post it was around 12k not 15.
The good thing about your build is you can really go in any direction from here and your not limited by any means. All the work done will just make a more efficient car either way. Congrats bro keep up the good work and keep us posted

It clears! I'll take a walk around video to show the sleeper car and how it fits nice and snug haha.

No hood scoop needed hehe.

That is too bad. Wanted you to have the real muscle car look with the ITB coming out of the hood!

Are you gonna have any air box and filter at all?

Yes the filters are on the way and should be here next week. They are imported from the UK, at least the ones I'm going with that aren't a rip off haha. They're cool looking you'll see them soon. Nope no air box.

Makes you wonder how it would look to have the trumpets feed directly out of the hood... Hmmmm... Looks like it would be simple to just flip the trumpets to face up...

On a longitudinally mounted motor that could be pulled off nicely I bet.

I like it without anything other than Nismo wheels and the slight suspension drop. Sleeper baby.

Will ITBs fit the Z engine bay without modification?

Wow this is very nice, but I wonder how far one could take a 07-09 HR motor? Or would it be just wiser to go SC/Turbo? When you consider cost and all.

FI is always cheaper price/power on these VQs

The hood on a 350z would have to be modified for the horns to clear. The G35 they'd fit though.

Building your own unique car is whatever route you want to go. Turbo or NA. I guess you'd pick up a little more HP tuning the exhaust cam though with the ITB and everything else I have.

How much more room would a Z need to clear? Maybe an HR hood swap would be sufficient.

HR hood swap won't work. Same issue. Easiest solution is either cut out around the ITB and run a hood scoop. Or just run shorter horns and it'll clear the hood.

You also gota get rid of drive by wire and run a cable but if you run your standalone all that will be easy.

If you put some work into it, you could get the drive by wire to work w/ a stronger servo motor.

Default Pipercross Trumpet Sock Filters

The Pipercross Trumpet Sock Filters came in so I decided to shoot a few pictures since I think it's pretty cool looking.

Alright if you see this graph you'll see how it works with me explaining the Xs.

@5000 +20-25WHP (1st X)
@5500 +20-25WHP (2nd X)
@6000 +25WHP (3rd X next to the big 300)
@6500 +20WHP (4th X)
@7000 +10WHP (5th X)
@7250 +35-40WHP (6th X)
@7500 +20-25WHP (7th X)
@7700 + 25-30WHP (8th X)

If you follow the Xs from left to right you'll see the gains.

The big 300HP mark is just showing where 300WHP starts from 6000-7700RPM is all about 300whp peaking at 315.

Keep in mind the tune isn't really complete because this was before any midrange tuning and the top end was just quickly made because the 9PM curfew for noise had to put a stop to the tuning that night and I took it home. I predict its got some more on the top end and you'll see even more under the curve later on too once they have time to tune it fully.

This graph is intended to show the before and after gains in the powerband for ITB vs stock intake setup.

I finally understand your graph now! I've been wondering what the top dyno run connected to below 5k, but it's basically you plotting it based on your other video.

It's really interesting that both setup realizes max power at a very similar rpm and by looking at your previous manifold I noticed that it's a log style one. It seems that the entire power curve is just shifted upwards by 20-25whp, is that also true down low? I would have expected a more gradual increase in power as rpm climbs. Too bad you don't have a torque curve on there.
