Shaker hoodscoop effectiveness

[Foghorn]

Is there any data on the functionality of the shaker hoodscoop available?

The small tube that connects the left side of the scoop base to the airbox doesn't appear to flow much, if any.

Has anyone thought of a modification to increase the scoops effectiveness?

Any thoughts on utilizing the supershaker base and an air inlet tube to the airbox?

Thanks in advance!

I could be wrong, but I think the PJs have the scoop sitting on top of the OE plastic Ford intake.

To make the SuperShaker work, the upper part of the S/C was shortened by half, with the TB mounted about center or less than.

I would figure a similar process would be needed for an N/A version.

The Techo Butterfly hood also uses an air inlet tube leading to the OE airbox.

On a supercharged car like the Dark Horse, my understanding is that the SuperShaker helps provide sustained power levels -- it simply doesn't run out of air as easily at speed.

It provides cooler air to the air box, but has little if any "ram" effect on the PJ.

The Supershaker is a completely different story. I believe I read somewhere that at speed there is .5 psi in the scoop, which would make a BIG difference on a PD blower...

The supershaker takes in all of its air from the shaker scoop, the new air box and filter sit right on top of the supercharger.

It might be effective in bringing in fresh cooler air into the airbox but it wont pressurize it! saleen cut the bottom out of the airbox.

as for using the supershaker base.. it would take some serious modifications and or extensive tubing. probably not cost effective for any or small gains.

Regarding using the shaker hood scoop to supply air to the engine. I have remodeled the intake tray and asscociated intake tubing to flow air from the shaker only.That giant saleen made hole in the bottom of the airbox is bad ju-ju. This modification solves the lazy performance issue created by the air charge being heat soaked from the drivers side exhaust manifold when the engine is at operating temp. It took about six months of tinkering but was well worth the effort. My initial problem was with detonation when the car was warm and subsequuent performance loss. The system I made has been in use for a year and made from a combination of fiberglass reinforced resin, off the self ABS rigid tube and high temp. silicone couplers. It works great! I can post some pictures if you would like to see.

I would like to see some pictures. Please!

Sounds Interesting!! I would love to see some pics! Please!!

You are viewing pictures of the initial mock up for testing. Most of the difficult modeling was performed on the intake tray which is covered up. The system has now been clearanced , sanitized and painted (to make it look purdy). I'll post more recent photos of the finished system tomorrow. I should mention I ran my car at the autoclub speedway (fontana speedway) in a redline track attack event a couple of weeks ago. A employee of Skip Barber driving school asked to run the car and I obliged. He took my good friend George on the ride of his life while I snapped pictures. George relayed that on the third lap they entered turn one flat out in fifth and maintained pedal down thru the turn. Just like the NASCAR guys! Car performed beautifully. Nothing came off, blew off or flew off the car at speed.

I hope you have an air filter hidden in that contraption.

[Killerkane]

I agree that the pictures posted would lead some to call this mod. a contraption:smile:. Maybe I should have waited to post pics of the final system (tube alignment,joint blending, final fitting and paint). Not a lot of room exists in the Mustang engine bay and packaging was driven by those constraints. To solve my detonation issues I needed functioning ram air not a hood ornament. Regarding your A/F statement, I fabricated a air filter with materials from the original Saleen K&N and this is fitted in the coupler just up stream of the MAF. In the first picture you can see a sump in the intake tray just above the drivers side valve cover. This was designed in to catch moisture and vent it to the ground. I'll post current pictures tonight.

What would cause detonation issues?

[Killerkane]

High intake charge temperatures mostly and fuel octane level. As stated in my earlier post Saleen removed the bottom of the stock airbox and that the bottom of the airbox is located just above the drivers side exhaust manifold. What happens when the engine bay comes to operating temp.? The exhaust manifold cooks the air entering the airbox thru its new manmade hole. The Saleen airbox modification is nessesary to exploit its low restriction A/F and large diameter intake tube but once the engine and bay is hot the heat soaked aircharge kills performance. Did Saleen put that tiny ram air tube in the airbox to counteract or cool the air wafting off the exhaust manifold ? I don't know. Its an interesting question. I just chose to fixed the problem. Little arrows to the right show the location of the in-tube filter.

Never had detonation issues in any of my 20 minute sessions at Hallett. I dud run the recommended 91 octane fuel however. Not sure why yours is different, but I hope your setup works fir you. I would question its effectiveness. Any test results? Performance gains?
