Another Truck?! Third Time's the Charm TURBOCHARGED

What can I say. I like em fast and hot

 

I'm bad at self regulation... so I pulled the trigger on some 2.5x14 King resi shocks with compression adjusters. Needed the right suspension to mockup around while I build the back of this thing...



In the meantime I am working on my rewire project and have also gotten some bushings to change in the front.

 

Nice find. Clickers definitely add a nice tuning layer. I am a fan now.

What bushings? Upper and lower A-arms?

 

Just doing the upper a arms again. Looks like SPC change the x-axis joint manufacturing. Look entirely different than my other replacements now so I'm hopeful even though they don't really need the last all that long now.

Oooh that looks like a great fit in there
My clutch fan sucks a ton of power

 

This the PWM fan setup you mentioned earlier? You planning on using a PID controller or something similar?

 

Yeah this is fully controllable from 0 to 100% and with soft start. I was going to do a basic engine temperature to fan percentage curve in the Haltech. But I'm also considering having a manual override two position switch to turn it off for water crossing or to turn it full on in the event something goes super wonky. But I'm kind of thinking I don't even need to turn it full on side because I can program that into the Haltech for a multitude of reasons to make the fan max out. Also going to have good air conditioning cuz I can turn the fan up when the air conditioning kicks on in the software too. Should also keep my intercooler a little bit colder as well since that core is right in front of the air conditioning one

 

Awesome!

As always, I love your approach to your truck and I plan to steal a bunch of your ideas (with proper attribution, of course ) when hopefully the time comes!

 

Thank you! You're more than welcome to copy anything I do, hell I'll even help you copy it. I didn't realize you actually asked a more nuanced question than I answered, a lot of things in Haltech are PID controlled, but only if they have some sort of feedback. We typically in regards to ECU stuff refer to that as closed loop control. In the case of this fan it's just going to be basic open loop duty cycle. Won't be any feedback, I'm not targeting a certain RPM or blade surface speed also I wouldn't really know how to get that information out of it without strapping extra sensors on since it isn't powered by a stepper motor. I'll just have to bump the duty cycle up or down to create my fan curve by monitoring it myself and seeing what has the most effect on temperature drop in critical situations. But even right out of the box if you do a linear curve rising with temperature beyond thermostat opening threshold they actually respond pretty well we've done this on two other cars.

 

Nice. Totally makes sense. I just know that you can get pretty clever with the Haltech depending on whether or not it has IO availability and it’s the right signal format.

We do a lot of tuning things at work for BLDC motors and our flow bench measurement setups so I have a pretty decent grasp on PID and closed-loop vs. open loop feedback. But for some reason, I have a hard time getting my head around stuff like how our stock ECUs move from open loop to closed loop or the other direction. That’s where your thread and the Haltech thread are great for me to lurk in so I can get a better understanding of all of that. It’s fascinating stuff when you get to pile that on top of stoichiometry, mass and volume flow, etc. which also strangely enough ties back to my real job.

I’m always down to learn and I love chipping away at my ignorance with all of this stuff!

 

I'm honestly curious if it'll be able to provide enough cooling. Thinking back to all of those old threads of people saying they could never get an efan to work right and would be overheating on the trail or something. Albeit those are old posts and without using a standalone ECU to control it.

 

I would be worried about using an aftermarket fan setup absolutely. Because quite frankly the fans that you can buy in the aftermarket are just plain terrible. And often people don't build great shrouds either. My goal here was to make sure everything is shrouded properly and this is a Ford fan from a large SUV. When this thing gets to full speed it's pretty impressive actually.

 

Is that the same fan that was used in early '90s Taurus and Thunderbirds? I just saw a youtube video claiming that's the e-fan to get, and that it's good for something like 5000 cfm.

 

That one is an old tuner's favorite. And it's absolutely one of the best fans you can get from the junkyard. We've put them on a lot of stuff. I would call this one more of its spiritual cousin. Unfortunately that Taurus one is becoming harder to find now but it's also a very awkward shape so unless you have a very wide radiator it's hard to cut it into a usable shape for something. Our trucks have pretty square shape radiators. But totally those Taurus fans are serious business and if you can find a way to make one fit on this platform it would be a winner

 

Here it is functioning I still got buttoning up to do obviously but it's all bolted up and temporary wired so I could test everything.

Awesome stuff, definitely like the idea of being able to shut the fan off for water crossings

 

Long as it has a good shroud it should work a treat I think.

My biggest gripe with them is they are freaking loud.

 

Well I seriously doubt I'll have to run this at very high duty cycle much if ever thankfully and below about 80% it is pretty quiet.

 

Yea seems like pairing a standalone with an "X" brand OEM fan seems like the way to go. After all, those OEM's have heaps more resources and funds to put towards product development than an aftermarket brand so the end result I would expect to be more fully fleshed out for the application.

Oh man that's awesome. The rag test looks super promising.

afaik, the factory clutch fans are either on or off. No in-between, so the e-fan should be a lot quieter in like 80-90% of scenarios. I mostly notice the power draw on my clutch fan at lower speeds. Like pulling away from a stop.
