Post Maf Tubes & Drop-ins, worth it??

Thinking of switching to G3's or some other form of intake with a harder intake tube because I am tossing the idea around of getting N2O again and use that at the track.....

oh ok... well that's understandable. Remember that Motordyne is going to be working on an intake set-up too... don't know when it will be out though.

also I think I read that the diameter of the maf section of the g3's are larger than stock so it leans the Afr out a little causing a bit more gains. you would probably see better gains after a tune with the g3's than drop ins and post maf tubes. again tho, requires more $$$

Red__Zed

a lot of the g3's gains come from leaning out the AF. a lot of times the gains disappear once it is brought back to safe levels.

The more people post here, the more I am am believing that drop-ins pmt's and fang vents are the better and cheaper way to go. I know that a lot of systems produce more power by tricking the ECU, the G3 design is obviously an excellent one, but for 500.00, is it really worth it?

Has anyone ever thought about insulating their airboxes with some sort of ducting tape or type of insulation?

Masa

There really is no need to insulate the factory(?) airboxes. Plastic does not soak in heat like polished metal tubes do and it is already ducted and sealed in the engine bay. It draws air straight from the bumper outside the bay.

I see you're right across the bay from me, more people here from Md. than I realized.

On topic though... keep in mind that every 10 degrees cooler there is a 1% increase in power.... hence the reason so many people try to find every advantage possible to keep intake temps down. Sitting in traffic or just idling, WILL bring temps up... even if only by a marginal amount, every little bit we're talking power.

Masa

Yep, surprised you haven't popped up at a MD meet yet.

On topic - no arguments that idling in traffic will bring temps up but once you get moving again the temps drop down drastically. I believe it was in the other thread that talked about the hps tubes where a guy took temp readings of the intakes at idle and at speed to measure how fast temps went back down. Since the plastic airbox and silicone tubes dont soak in heat, the intake temps drop down drastically when moving air passes through them. At this point it really is just nitpicking since when you are driving the car around normally it really won't matter and when you are tracking the car there will always be cool air passing through the intakes (hps tubse or g3's) where heat soak won't even be a problem - oil temps will be.

Have you considered the guys that get their Gen III's powder-coated, or perhaps some other coating applied that helps resist heat soak on the metal because there is another coating on it that is more resistant to heat? Say more reflection than absorption?

I have actually thought about that and wondered if the powdercoating would make things better or worse... I think even sitting the G3's only get about 25-30 degress above ambient temp though.

Jordo!

You could experiment with stuff like this

Heatshield Products

Would be tough to determine if it made much a difference without being able to log air temps from the ECU tho'...

I suppose you could pick up a couple of temp probes and do it in a DIY manner to get an idea how well it's working. May or may not show up on a dyno, espeically with fans blowing and the hood open.

Or, if you are looking to cool things down for a drag race... CryO2 intake systems

Reps for the info... very interesting stuff. If the weather is clear tomorrow i'm going to take the car out for a normal ride and try to get just an idea on how hot the airboxes get, sitting temps, and then harder driving temps. That will give me an idea if it would be benificial to add some heat shielding.

Jordo!

Thanks

If you can find a slender enough probe, you might just be able to kind of wedge it in the part of the airbox that holds the filter and clamps down, and still get everything sealed up airtight .

It would have to be something like a thin length of wire, but I think there are temp probes like that to be found realitively inexpesnively. That should get you a pretty good reading of what the MAF IAT probe is seeing.

Also be sure to take note of the ambient air temps (I guess whatever the Z's readout says will do) to see how much the airbox temps fluctuate from that.

yeah, this is going to take me a while lol. I'll post my results once I get everything I need.
