E-fan install was a success, but the desired result was not.

At highway speed, the coolant temps are higher. Only guess is at higher speeds, the fan is creating a blockage and stalling the air through the rad. Didn't have this problem with the fan clutch, but it is always locked on.

2 steps forward.......

FC Zach 02-20-2017 12:43 PM

Diameter of fan?
Shroud?
Controller?

Don't know. Half an FD aftermarket set up.
None (didn't have one with fan clutch either, broken)
Hayden adjustable temp with probe (giggity)

FC Zach 02-20-2017 01:33 PM

There's no reason it should be overheating with a controller and no shroud, regardless of fan size.

Edit: meant to say "at interstate speeds", driving around town is a different story.

Update on my turd.... we (me and dj) replaced afm. Thought that fixed it. No go. Tried adjusting tps. Back to square one. Took all the manifolds off again. Discovered shart gaskets. Ordered new non shart gaskets. If they dont fix the problem im getting a haltech.

Yes and no. At highway speeds, the air coming though the rad might be faster and have more volume than what the fan can achieve. What this does is stall the air around the fan, almost like creating a wind blocker, instead of flow. Now, if I set the fan 'on' temp higher, the normal airflow at highway speed should keep the fan from turning on, thus freewheeling and NOT hampering air flow.

I'm going to up the temp at which is comes on and see what happens. Right now it is set to come on at 180, which is too low.

FC Zach 02-20-2017 01:56 PM

Awesome for the gaskets being possible culprit, not Haltech. . However, if that is something you do is probably for the best.

If you have a good functioning controller, this shouldn't be an issue, especially without a shroud. (@ interstate speeds)

Yeah, at least 190. . Hell, your thermostat is probably just starting to open.

Gotcha. Yeah i figure if the gaskets dont do it then whatever it is thats causing it will be fixed with a new computer.

Johnny_K 02-20-2017 02:07 PM

Kyle, have you wired up an EMS before? If not you plan on making your own harness if you get a haltech?

Do you know how to tune an EMS? If not, do you know who you plan on getting you to help with the setup and tune?

Still waiting on word regarding pictures with the Slowica. . . Don't know what you charge but that's some income. .

Im talking to Brian about helping me build the harness.

Zach ill do it for $150. Im ready when you are.

FC Zach 02-20-2017 02:21 PM

I should be free the weekend of March 3rd. Let's try then if you're free.

True, but if it is blocking the air, then it is getting warm, so the fan kicks on thus creating a viscous circle.

FC Zach 02-20-2017 02:26 PM

True, I hate those viscous circles ;)

rotorbrain 02-20-2017 10:23 PM

viscous circle?!?!

Planning. . . yes. . . but, not if I have to get a room on my own for the whole event. I don't think I have enough bargaining chips to swing that expense by the wifey!!! I sent a PM to Kyle. . . we'll see how that goes down.

Replied.

Vinnie,
Yea.. it's between 70k and 80k miles on it. Closer to 80k really at this point. I don't think it'll get there though. It's coming out soon. REW on order.

The GM coils that BHR uses for their kit have an auto-discharge to save the coil if the dwell time gets too high. Mazda calc dwell at crank based on voltage and RPM. So if the battery is dying or it's a particularily cold morning and the engine is cranking slowly, the coil can auto discharge and sheer the apex seal.... while starting.
How do I know this, I was warned about the coils YEARS ago by a MoTeC Engineer, and I've seen it, or spoken to someone about it three times now.

Noooooooooooooo! Turbo's don't belong on an RX8!

Johnny_K 02-21-2017 10:35 AM

^ sure they do if it powered by a REW or 20b.

TitaniumTT 02-21-2017 10:43 AM

Negative. The subframe on the RX8 makes it nearly impossible to get a turbo in a decent spot. The mani's are either too long, or too short, it's just a nightmare no matter how it's done. And I would rather see an LS in an 8 than an N/A 20B.... now a shorty P-Port 20B would be something that I could get on board with :rofl:

Johnny_K 02-21-2017 11:23 AM

^ pfft, this doesn't look complicated at all ;-)

Except that the turbo it practically mounted outside the engine bay LOL. . :)

EWWWW... new info to me...

Just the 20b block and assembly was going to cost me more than the entire REW build for my same HP goal range. In fact... I could swap the RX8 and MR2 for the cost of the 20b build. I tried to work my budget every way I could think of, but I couldn't support the 20b cost right now.

Less turbo, less problems.

You'll see.

They are. . . With a Cajun dry-rub seasoning and smoked! Meat falls right off the bone and is absolutely delicious too :p

But I agree, turbos are fun!
