Ram Air.....

Anybody running it on there maverick?? Pics would be sweet.....

 

What kind?
A functional hood scoop?

 

No a box system with the ram air tube mounted to the core support. I may buy one of those kits from RamAirBox.com or I might just weld one up out of aluminum. I am looking at a new tig welder but I aint rich so who knows....

I should have hood clearance with the carbon fiber cowl hood that should be shipped to me in a few weeks

 

Ivy is. Or rather was. (Fordman) I'll see if I can dig up a picture.

 

Did you get one of Derricks hoods you sly devil?

 

He gave me free one in trade for a Video

I can't wait!!!!!!

 

Hmmm...must have been more than Mavericks on THAT video. Sounds like a little blackmail involved.
Like courier11sec said...You sly dog! :evilsmile

 

You know believe it or not. I did catch some interesting conversastions with my vid camera but you know......:evilsmile

 

I'm interested too. I've been told it could be a huge improvement, maybe take a tenth off in a quarter mile.

 

I have a 1969 gto judge that has ram air. The scope incerts in the hood are very close to the Maverick. Infact a regular gto without ramair has dumby scoop incerts just like the grabber. The ram air scoops have a door that opens by a cable mounted under the dash just like the old choke cables. The air cleaner has a foam lip around the top that seals against the bottom of the hood. Do a search on google and cheak it out. I have always thought the same type setup would work on a grabber hood.

 

Typically it is worth .2 to .3 if everything is tuned for it.

Tuned for it means"a fatter jet in the secondaries" and possible a smnall timing adjustment. More air means you need more fuel

 

.2 to .3 is huge!
That is 20 to 30 rwhp.

I am no rocket scientist, but I respectfully disagree on that level of improvement.
Ram air actually does not provide any sort of ram or supercharging effect.
It just lowers the air intake temp, which in turn provides a more dense fuel charge. More power for sure if you actually lower the intake temp, but nothing like 30 rwhp.
I could live with the idea of 10 hp, or .1 in the quarter, but that is even stretching it because the air intake temp would only be lowered while in forward motion over 40 mph. Therefore, the effect would only take place on the 2nd half of the track, and even then, there is no real time for the heart of the engine to benefit from decreased temps.

I had RA on my Z28 and it never showed an increase unless I was moving, and for at least a few minutes at that. The difference was profound on the highway though. I would have to drop out of 6th gear to pass before RA, after it was eager to pass without the downshift.
If I had just come off a light or in heavy traffic, the car would actually detonate more than previous due to the proximity of the RA intake opening to the radiator support. Without air flow, it actually drew heat off the radiator at the front of the car, causing the detonation that was not present before.

I think if RA is to be used, it should be either home made to save dough, or done via a functional hood scoop so you have looks and value.
My Mopar scoop on the 75 always worked great.
Wasn't near the radiator to take in heat, and was wide open to frontal air flow. I didn't seal it to the hood, however I only cut the hole big enough to fit the air cleaner through with very little clearance. That is all you need. Sealing does nothing to 'compress' the air.

Dave,

You do in fact create a bit of boost. You need to be going upwards of 75mph below that it doesn't do much except let cooler air in. I read somewhere at 80mph it was like 1psi to 1.5 psi of boost.

Just for kicks I will buy this system and and do my own tests.

 

They will not allow me to run my factory Comet hood scoop in the "street car" race classes in this area, they make me put duck tape over it. They say that it gives the car an unfair advantage.

 

Good grief.
