Are OBD1 cars data-loggable???

Marlon

Would be awesome to post it! Do you think there's much room to "open it up" a little to the left (towards drivers side) as it is trimmed down? Not sure yet, but I'm thinking that a very tastefully pop rivitted light gage aluminum sheet will do the mod since not much 'sticks' to that slippery plastic stuff.

On second thought, you could almost fab the entire rig out of empty M-1 cans!!!

A concern would be potentially 'blocking' additional cooling air that is introduced to the e-bay...

Pictures would be great but better yet, what changes in power have you been able to assess how did you assess them?

Marlon, why half-*** a project that might get you half of one horsepower? Here are a couple of tips.

Add one of these:



With two of these, one for each intake pipe:




And then you might be up to two-thirds of a horsepower!

No change really from my butt dyno.

What is needed are dyno runs with an OBDII data logger to measure the intake temp for the various runs with and without the intake.

I am waiting for my OBD scanner group buy. Then maybe some dyno time?

Noah - How come you finally getting rid of yours? I did not see it on the swap meet

That won't quite do it. Measuring just intake air temp ignores the fact that you might get less air flow. You want to know engine power, and the only real way to do that is either dyno (not good here) or calculate at speed based on accel data using a data logging system like AIM, DL1, Traqmate, etc. In the analysis software, you input vehicle parameters (weight, Cda, Cdr, etc.) and look at calc'd power output.

Or, better yet, just put a dyno in a wind tunnel.

Look at what Porsche Motorsports (I think it was actually a Cartridge Ltd?) did with the 997 GT3-RSR intake for a workable solution.

This is what I had to do to make the snorkle fit under the standard tail lid.

My idea is to fit a slightly expanded 'funnel' area onto the rectangular inlet. Might not be worth the effort though. But the Streather book has a photo a a 993 turbo and yuo can see the snorkel coming up through the intercooler assembly. I'm sure there's many more photos out there that depict how the snorkel actually is oriented in the turbo airflow.

I think this method may work even better, with these modified home ventilation turbines, each driven by a 12v blower motor reversing the rotation, you could, with just a little amount of body work and some internal ducting get more than enough air without interfering with the spoiler operation. Plus Imagine the extra torque it would produce at idle! You could save on having to upgrade to a LWF because the extra torque would have no problem spinning the dual mass FW.

This would bring so much cool air in that you could actually take a duct off the this intake system to blow over the back deck to eliminate the dreaded speaker dust issue: https://rennlist.com/forums/993-forum/370110-speaker-dust-issues.html

now THAT will make some HP!

Not to mention the fact that you could install an engine-mounted hibachi and grill up some burgers and dogs while you're stuck in traffic!

Marlon

Somehow - in a odd way - that system looks pretty darn good
More speed -
more turns -
more flow!


I think the hibachi would fit perfectly on and intercooler deck
