94/95 cobra intake

Finally a 5.0 · Jun 23, 2005

is it gonna hurt performance on stock heads? i'm assuming low end torque would be affected (how much?), but would the gain up top be worth it (how much)? thanks

I went from a 14.89 @ 95.27mph to a 14.17 @ 98.99mph with a ported 95 cobra intake, and 70mm BBK throttle body. 'nuff said.

EDIT: Oh, maybe I should add that it really pulls hard even past 5500 now.

The dyno runs I've seen put the GT40/Cobra/Explorer intakes right with the torque curve of the stock intake. The 94/95 Cobra is basicly the same as those intakes with an elbow. I'd say you would not be able to tell any difference in the intake until you pass 3000 RPM, then the Cobra intake will be producing more HP than stock. You should see no loss, only a gain. All the mags show the GT40 style intake making more HP & TQ below 5K than the BIG name intakes. If you have the lower ported it will beat them to 6K too.

If you don't want the 95 Cobra intake, I'll take it off your hands.

Yeah intake manifolds are great even with stock heads, i went from 14.37 @96 to 13.91 @99 with an eddy performer.

As above...especially the lower intake as far as being restrictive.

A "typical" bolt on upgrade is the "front" of the block, which includes a K&N filter, larger MAM, 65mm TB and nicer intake such as the Cobra, Edelbrock Performer, or TFS street. There is a lot of gain to be had with this combo upgrade.

Good Luck

thanks guys. also, is the cobra tb bigger than the gt's? could i use that for a gain or just buy a 65 or so? thanks for all the comments.

scarless- I'll keep that in mind

Nope, both the Cobra and GT came with a 60mm.

I don't think adding a 65mm TB with just the intake upgrade will get you much of anything with the stock heads and iron headers. That said, it wouldn't hurt either.

dstanggt50 · Jun 24, 2005

I would recommend it, I felt a good increase w/my gt-40 upgrade, I didn't put the t/b on until after the h/c/i, so I woudn't know about that, but definately go with the intake upgrade.

thanks guys, looks like i might have tmoss port the intake for me and then i'll put it on, and leave the stock tb and all that. how does that sound?

or would a ported intake be too much for a bolt on 5.0 with stock heads?

If a Cobra intake isn't too much, then a ported stock intake sure won't be. You'll be fine.

lol...no im putting on the cobra either way, just thinking if i should port the cobra before i put it on, or would that be too much?

scarless · Jun 28, 2005

If they are ported larger than the opening in the head, then yes it can hurt flow.

tmoss · Jun 28, 2005

No need to port a Cobra for stock heads.

pickardracing · Jun 28, 2005

What about for P's?

Porting needed for that?

My mistake, I saw something about TMoss porting an intake, and I assumed it was a stock intake. That's usually what people get him to port. Look at it this way, even if you DO port it, it's not gonna make your car any slower. It might not help out right now as much as if it was UNported (although my ported Cobra REALLY packed a punch), but it leaves room for improvement later on. I'm all about leaving room for improvement.

dont port the cobra intake on stock heads, or gt40/gt40p heads, it will hurt your performance as in no low end torque. at all. You could port the intake though if your heads were ported as well, and you had the cam to run that airflow.

Spoken like somebody who hasn't tried it. I saw gains all around with my ported Cobra intake. While the low-end might night have been as spectacular as if it had been unported, it certainly did not make me lose power. My o/r h-pipe made me lose more low-end, but you don't see people saying don't get one cus you'll lose to much power.
