Sure Bill, that hood will close....

Just asking about your equation.
yes, no JSMath functions on phpbb!

The pressure at the plenum/iris is one thing, but the cfm across the entire system is another.
The stock intake does a poor job FLOWING, but has a relatively low pressure drop across the air filter. I speculate that the "ribs" or stretch section do the most damage.

Interested... Was there benefit or detriment under 4200RPM? Resonance doesn't discriminate, and MAF technology hasn't changed much. I'd really like to see some dyno action from the other end of the RPM spectrum, which has been proven to suffer from this sort of mod in other applications.

Re: Gene's DIY CAI thread

I'll post up some dyno results this summer when I head over to MASE Engineering. I have no problem swapping parts on a dyno day!

I have to get that 3rd pedal I have been wanting and finally a Hydra ECU before then.

On another note, after my recent mods (see my thread in the general section) and a good dose of seafoam I can finally feel a distinct step in power when I get on it from a standing start.

Nah Bill, you were second on the scene, I was referring to Mychailo's post.

Harvey,

You are correct. I actually borrowed Mychailo's instrumentation when I did my instrumented runs.

-Bill
p.s. the hood is a classic glass fiberglass piece. fingers crossed that I won't have to do any cutting, but I have my doubts

So what's the story with the "scorpion" intake? Will it do anything the tomyx style intake wouldn't do? Regardless, that looks really badass dude. I could see something like that pulling air from a filter under a hoodscoop. I wonder what that would do in terms of power.

Bill, with some solid mounts we could drop your engine 2" for a lower center of gravity AND more hood clearance!
Less angle in the driveshaft as well!
BTW, phone broken?

Re: Gene's DIY CAI thread

OK I finally got around to taking a few more pictures of my CAI
This is what it looks like now







The line going to the valve cover is the breather, I removed the pcv system and replaced it with a breather filter and this line was apparently venting to atmosphere. I started getting fumes in the car

First I started by cutting out the Accordion section of the stock tube, for 2 reasons first it allows lots of movement, and second using smooth walled tubing should help air flow.

I cut it as close to the idle control nipple as I could and still put a silicon coupler on you can cut it with a hacksaw. I think I used tin snips. I used a 3" silicon coupler from oreilly's. Part # 8771
$7.99 needs 3 for my setup. I also needed to heat it up just a little to open enough to go on.
Then into that goes a 22 degree bend part #8728

at $11.99. This will connect to a 4" straight piece part #8708 using the clamps that come with all these pieces $8.99

Which then connects to a 45 degree bend


Part #8738 $11.99. Using the second of the silicon couplers this attaches to the stock MAF again needing some heat to fit. Then maf adapter part number #81413 $13.99

Discarding the plastic piece as it is for a smaller diameter piping. You will need to line up the inside and drill new holes to fit your maf.
Then the maf adapter couples to the 90 degree bend part #8698 $10.99

Then that attaches to a 6" straight part #8718 $9.99

Then put your filter on the end. I had a filter so that was not included in the price but if you need one part #8136

cost $24.99
With out the filter it was $91.99 A little higher then my initial estimate.
That is what I did as I pieced them one at a time if you want you can get the short ram part # 8208 for $39.99

comes with one coupler and 2 4" and the 45 bend which means you would only need the 22 bend the 90 and 2 couplers. You do need a straight piece inside the fender but the 4" may be enough I had the 6" so that is what I used.
Using the Short Ram without filter its $78.95
All the pictures are gone.
Kinda makes this thread less helpful.
