New Air Filter

[Jeriatric]

My concern is pulling in hotter air will give worse engine performance, I know on a car cool air is king in an intake.

Agree. Just not sure whether the air (with all that plastic removed) will be any warmer/cooler than what the temp sensor to the ECM is reading. That said, more air can't hurt as long as it enters and vents/escapes DOWN as opposed to out the seat cracks.

One thing I guess to keep in mind is how often the engine compartment air is "turned" over, not like the air will just be sitting there long enough to get really hot like it may be now?

Do we know what CFM the throttle bodies are on a Spyder, that figured in may help...not that we know how much it's pulling at idle or low speeds though?

I was thinking that 2, but like you, I have no idea what any of this looks like inside. lol

This is the air box, filter, and resonator that I took out of my RT.

Is that the same on an ST?

That looks like 20 lbs of plastic!!! :gaah:

I wonder if when all the extra plastic and tubing is removed, if an simple cool air intake tube can be fashioned to "help" direct fresh air toward the new filter.

Would be a nice addition to a new production air filter, just saying. Lol

Haven't some guys installed fans to help pull air when stopped are moving slow in traffic as they tend to overheat if sitting to long. Gets mighty warm here in the desert.

Yep. after all that plastic mess is out, a few have done, and I am planning on taking the "hose" portion and mating that to a 3" Attwood bilge blower to draw in cooler air from around the fender area and blow towards the new intake. CyncySpyder shows pics of that in his big thread.

Are there any other lines (vacuum) or sensors attached to these plastic parts that have to be dealt with?

I wonder how a service dept would feel about this and warranty issues.

I've never seen a ST so I don't know. Yes it is a lot of plastic.

The crankcase vent plugs into the breather housing and my adapter plate has a connection for that.

Cool, thanks. :thumbup:

Air intake temperature is used to correct fuel quantity (pulse width) since air temperature effects air density. (colder air is much more dense) Approximately 70°F is generally used for 0 correction, temperatures above will result in less fuel to compensate for the lower air density, and conversely temperatures below 70° will result in steadily richer (by volume) mixtures.

The hotter the air the leaner the mix. Things get dicier when temps are high and you're @ or below sea level.

My concern is pulling in hotter air will give worse engine performance, I know on a car cool air is king in an intake.

By engine performance I meant power, not MPG.

Not really concerned w MPG, I have other vehicles for that. Lol

Those charts show better MPG, but w that added intake heat I'm sure you lose some power.

But the reported warm air temps referenced in the charts are lower air temps than the real world air temps we deal with many months out of the year. Before adding under tupperware heat.

Performance or economy? May = Location

Any ETA on when the intake will be in stock? :dontknow:

I just brought the first batch home from the machine shop today. I have to prep them for anodizing then ship them to the anodizing plant. Everything else is ready for the first batch. I'm guessing I'll have them on the shelf the week of 3-24. Here is a photo of some of the parts sitting on the machinist work table.

Awesome! Thanks for the update. Weather is getting warmer and the wife is getting antsy. I let her borrow my Spyder yesterday so she could go out riding.

Lucky you, the temperature is nice today and the sun is shining here... and snow still in some spots and the road to the highway is a mud pit!

I'm working as fast as one old fart can...

Looking good!

Will they be clear coat dipped or? Just curious.

It surely wouldn't be too hard to move the sensor to a more relevant location in respect of air temperature once the air box and resonator are out of the way.
Just my tuppence worth!

The pros and cons of moving the sensor have been discussed. A lot. Not sure if anyone has actually done it?

Have no idea how much difference moving it would make. A few degrees (less than 8 or so) one way or the other may or may not matter in the grand scheme of things. One thing is for sure :dontknow:
