What is the max HP the tubular gt40 intake will handle assuming I have a good set of heads and cam?

The reason I ask is I have a goal of reaching 350-400hp in the future with a 347 and a good set of heads and cam and if I have to forced induction. I know there are better intakes such as the trick flow ones but I really like the look of the tubular gt40's. I think they have a really aggressive look to them. If it holds me back I will likely look at something else but if it could handle the flow I'd like to find one of these with the tubular look.

It flows ok for a decent N/A set up, but you will be restricting yourself once you go FI. The other downside is that you are going to pay a pretty penny to get one, as most that I have seen have a relatively high asking price.

I think you've got that a little backwards. Boost can make up for a mismatch combo. N/A is less forgiving. You could probably pull off 350-400HP with a tubular intake, but it will definitely need to be ported, and you will definitely need to put the engine together right. At that HP level, it's a choke point, no doubt. If you made a similar combo with a better flowing intake, you will make more power, but if you're after looks more than all out power, it can be done with that intake. If you boost it, it will do it easily. N/A is where you need to pay attention to details to make it work.

Here is an article that shows some different intakes including a ported GT40 on a N/A 347. It is a magazine so take it for what it is worth.

if you talk to anyone whos wasted their money putting a ported gt40 anything on a stroker theyre just sayin they like it so they dont feel like an idiot. Fuck that. Get a good intake and do shit right

I think the GT40 tubular is one of the best looking intakes ever made, but there way over priced and they dont produce enough power to justify the cost

[FastStang91Lx]

Exactly

[ryanw]

I'm surprised....with as much money as these gt40 tubular intakes seem to fetch price wise. i would think that some company would have started remaking them, they would sell like hot cakes

i know the cobra and the explorer intakes are the cast version of it, but still....people really want that tubular look, and they could also improve upon the design to keep up with all these other better flowing intakes on the market....

i have a gt-40 lower port matched to my gt-40x aluminum heads and a 94-95 cobra upper intake manifold stock with no mods and a 70mm throttlebody and im extremely happy with the numbers i put down at the dyno. If you read that article that was posted on testing the intakes to the gt-40 you will see that none of the top brand intakes could provide the torque of the gt-40. Torque is what you want on the street and at the track right? The seat of the pants feeling of a high torque engine outweighs a high horsepower engine any day of the week in my opinion. Especially on the street.

Yeah, but old musclecars with the big blocks could pull a stump out of the ground with their torque, but still only crossed the line in the 13's if they were lucky. Yeah they weighed more too, but you need upper RPM horsepower. And horsepower and torque are relative anyway.

whats your car run at the track? and Im talkin bout strokers theyre fine on a mild 302

Intakes are better tested on cars, not off them. MID RANGE TQ is good, but it's rpm's and how high you can take them is what you want. Tq drops off there and hp goes up. Do the math. Your numbers are irrelavent. Your cramming a ton of boost into your engine. Do the same thing with the better parts and what do you think would happen? Higher rpms, more power, same boost or less depending on the head size.

Horsepower and acceleration is what gets you down the track. If you have a car that makes 500 ft lbs at 4000 RPM vs a car that makes 400 ft lbs at 7000 RPM, which one do you think is going to be faster?

A BLACK ON BLACK 95 GT VERT FULLY CONVERTED TO A 95 COBRA AND MODIFIED WITH ALOT OF GOODIES AND A BB SINGLE T67 TURBO KIT. 526.14RWHP 496.00RWTQ @6PSI

Is faster then both above said cars .

never been to a track in my life. I built the car for autocross. Im guessing it will run 11,s in the 1/4 but who knows. One of these days i will run it but not until i upgrade a few more things.

i agree on a n/a stroker.

on stock skinny azz belted tires they did - when you put slicks on them, did traction bars and the standard bolt ons we do today, it was a whole different story. Were you driving/racing back in that day?

OP - the GT40 will make the power you want without a bunch of boost. If you like the intake, use it.
