Box Intake?

[Brutal87]

Whats the benefit of running a box upper intake on a charged motor? Such as the Comp, Cartech, Down's, Holcomb "Civil Wars" boxes??

I have a ported Cobra right now.. Can I get better low end torque from the box upper & proted cobra lower?

I was even thinking about the complete TFS Box-R intake.. ???

you will LOSE low end with a box intake.

Also, if your needs require one, do not get the COMP box as they are not worth the material they are made out of

:agree:

You gain a less restrictive intake when you go to a bread box intake.


. . . it also makes it easier to get to the driver's side valve cover. :D

That's a nice intake, but you may need a cowl hood for that one. Check with slvrbullit (http://forums.qwiksnake.com/member.php?u=4); I believe he test fitted one on his car a little while back.



Edit: I just saw Tommy's post in this thread refering to the fitment of the TFS intake. ;)

It's not that I require one.. I would like to run the taller breather style valve covers but they won't clear the upper. I can't fit an intake spacer without changing the hood. (Can't change the hood due to the hand mixed paint color :( ) Sooo I think my only option is a box intake. Your right about the Comp.. I put one on a '92 GT droptop I had a few years back.. It was a VERY cheap intake. What do you think about the Trick Flow Box-R? My cam doesn't help down low either.. (Trick Flow Stage 1) As it is now.. The car doesn't come alive until about 3000rpm. I was going to install a 3.55 but what if I use a 3.73 gear to compensate the loss of my low end? :dunno:

Thanks for the link.. Whats the clearance difference (if any) between the Fox & SN95's? He tried it on a '95 right?

You'll have the same problem with the box intake. The throttle cable bracket will hit your valve covers without an intake spacer. :yup:

Alot of people run the box intake to loose down low torque so the car will hook better on radials.

My Trick Flow Stage 1 cam has all the power you'd need from 2k on. Why does yours wait until 3k? Italian drove my car and said it felt like it had 4.10's or something. Do you have 19# injectors? If so, switch to 24's...I noticed a HUGE gain in bottom end with that swap. I too have the TFS1 cam and a cobra intake.

As for box, you shouldn't need it if your Cobra is ported at all...mine's port-matched.
I've seen as much as 840 rwhp through a ported Cobra (cut open and welded) with a Novi blower several years ago.

The intake I tried came off my friends turbo'd 92 Coupe. He has a 2.5" Cowl hood and has issues with it hitting his also.

I have an R that is going into my convertible. I am going to run the HPM drop solid mounts, the intake sits about an inch higher than the TFS Street heat I had on the old engine. Here is a link to the pics of my engine.http://sinope.darkstarllc.com/~forums/showthread.php?t=2135

fwiw...I ran the comp plastic box on my speed-density coupe for a while. Stock except for 1970 351-heads...8.98 @ 80 in the 1/8; that's in the 13's 1/4. I liked it...but gave it away nonetheless :(

I had one of those comp polymers, but it wouldn't stay sealed up. Seemed like a plastic piece of junk to me, but I did pick up with it when it was right. Nice hood clearance and valve cover clearance too.

Thanks for the info guys.. :metal:

I guess I'll stick with my Cobra intake.. I picked up some 42lb injectors, 75mm T/B & C&L 76mm MAF. I'm also thinking about getting the AFR 185's. The longer I have the car tore apart.. The more I change my mind.. ;) I just have too many projects going on right now & I can't keep my mind in one place.. I in the process of installing heads on my GN.. It's hard to work on a Ford & a GM at the same time.. :jester:

Thanks Again.. :chug:
