MAF temps are above ambient due to engine bay heat. Once the car starts flowing air you'll notice the MAF temps drop drastically as its pulling in cooler, fresh, air.

Re: Whats new with Teh Gheyrod...
 

Hmmmm maybe. Yea the stagnant air is going to get ingested and replaced with cooler air but the engine is going to be pumping more heat into the bay as well throughout the pull.

Something about this temp data erks me the wrong way. The sensors arent even from the same manufacturer are they? How does the manifold sensor calibrate?

Re: Whats new with Teh Gheyrod...
 

The manifold temp sensor is a GM IAT, mounted the the top of the intake manifold plenum, next to the map sensor. The other sensor is in the oem MAF. This has been discussed to death on evoM, and its what we all see. Part of the issue is the sensors (MAT) themselves becoming heat-soaked, but once air starts rushing through them they cool down. The important data is near the end of the pull, if temps rise or stay flat. This is a pretty good example of staying quite flat, esp considering its just on the dyno not on the street where there's a LOT more air coming through the engine bay.

If you think this is fuct up, wait till you see what my car does with the alky spraying ;)

Re: Whats new with Teh Gheyrod...
 

When the car is cold (been sitting overnight for example), the sensor readings are equal.

Re: Whats new with Teh Gheyrod...
 

I think if we had an Audi dyno day fan setup, then the intake manifold temps might be lower than the MAF temps.

Re: Whats new with Teh Gheyrod...
 

I don't need the Audi fan setup, my manifold temps are already lower than temps at the MAF ;) Manifold temp is the purple line and MAF temp is the blue line.

I'd really like to get a temp sensor to log ambient temps too; I might have to look into if that's possible.

Gheyrod got its spring waxing and door/hood/trunk seal greasing today! Tempted to put the summer floor mats in too.

Re: Whats new with Teh Gheyrod...
 

I'd wait on the floor mats. I heard we're supposed to get snow this week.

Where does that mount?

Re: Whats new with Teh Gheyrod...
 

^WTF is that for.

Re: Whats new with Teh Gheyrod...
 

It ties together the front control arms and the chassis.

Re: Whats new with Teh Gheyrod...
 

huh... Interesting. Any tests or anything to prove this actually does anything other than lower ground clearance?

Re: Whats new with Teh Gheyrod...
 

Haha

The M had a brace like that, was called an X brace, and you could definitely feel it stiffen up the under body though.

Re: Whats new with Teh Gheyrod...
 

And its white to match teh gheyrod. Aww fer cute :D

Re: Whats new with Teh Gheyrod...
 

Nope, but I had something similar (Spoon X-brace) on my S2000 and if it can make a difference with that ultra-stiff chassis this should help with the Evo's chassis pretty nicely :) I don't mind testing out unproven products that I feel will be of benefit. Even if it doesn't actually noticeably stiffen the chassis, at least I know it will help keep the car in shape over time. When Scheides installed his front motor mount it was noticed that his chassis is starting to deform with age and its fairly common on higher mileage S2k's for the X-braces to not fit. Also, it really won't be lowering ground clearance by much since this bar is replacing some thinner, weaker, stock bars. Besides, I just lifted the car .5" a few weeks ago :D By biggest worry though is whether or not this bar will clear my Buschur 3" downpipe...we shall find out tomorrow evening!

Re: Whats new with Teh Gheyrod...
 

Even Miata's have sub frame connectors and braces available. I'd give it the +1, Maybe even add some X braces in there. What does it weigh?

Re: Whats new with Teh Gheyrod...
 

It looks like 14/16 gauge oval tube, mild steel w/ 1/8" flanges. I would guess 5-8lbs.

Re: Whats new with Teh Gheyrod...
 

Nice.

Re: Whats new with Teh Gheyrod...
 

John is probably about right at 5 lbs; its fairly lightweight considering the size.
