Procharged 2003

[Wagonbacker9]

I think I figured out my plan. I have a trans cooler circuit already (comes on with the fuel pump)... I think I'm going to add 2 more smaller fans to that on the back of the intercooler as pullers, and basically force feed this thing some more air any time its running, leaving my current fan setup as almost a "secondary" fan that kicks on when it gets warm. There is about 3" of clearance between the IC and the rad, so a puller on the IC is virtually also a pusher on the rad. There isn't really anywhere else for a significant amount of air to go.

I figured that, he was aiming the truck at the track for the most part, not really as a DD or many street miles. I was wishing for an Aviator way back when, and the KB for it like the 03/04 Cobra. Your truck is as close as anyone has gotten to that idea.

I like to like I got pretty close to that with my “Explobra” build from a few years ago. I am changing superchargers soon and I’ll hopefully be around 550 hp. Still AWD also.

Nice!

So just a thought. Maybe the 170 stat is actually hurting you. Too low of a t-stat will always keep the coolant flowing and not allow the rad to cool it down.

I can’t see how what the tstat is doing at 170 matters when it’s sitting at 210 and doesn’t want to come back down.

It either has the capacity to keep itself at the tsat temp, or it doesn’t, and today it doesn’t. With a little luck tomorrow it will.

Is this rockets old supercharged truck? Man that's a throw back! I'm going to be knee deep in a ground up rebuild on my bolt on / trickflow head 03. 6r80 swap, not sure what direction I want to go with the engine, she's got about 130K on her. Part of me wants to do a big bore stroker, part of me wants to refresh the aluminum block thats in there. I'm not looking for a drag car, but 500hp-ish daily driver would be fun. Very sentimental about my 03, and my dads 08.

Why the change to the procharger? I thought twin-screw chargers like the KB were the most efficient superchargers.

Yes, its his old rig. He tuned my GTO with me back in like 2011, and we've been friends ever since. He moved out of country so I picked up the project off him for absurdly cheap.

The change to procharger was essentially 2 factor: 1) the hope that I'd be fighting for traction a little less, and 2) a D1SC F150 kit fell into my lap for about half what I was going to be able to get my hands on a kenne bell for. Then beyond that theres the fact that I've always enjoyed "off the reservation" kind of stuff, so once I determined that F150 kit would probably fit, it was kind of a self-issued challenge to make it happen. As it turns out, the clearance issues were a LOT closer than I thought they'd be between the valve cover and hood. I have millimeters on each, and no more.

I'm sure Kenne Bell would tell you they're the most efficient, but that really depends on your definition, and your goals. As far as total power under the curve, yeah, probably it wins that. But peak horsepower for a given boost level, the procharger makes a lot less heat, so it wins that handily.

I'm guessing this thing won't 60' very well, but I figure that should help it not break things, and it should run like a beast out the back door.

Good plan. Traction with 2WD is a big deal, changing the type of supercharger might be a really good idea.

The Autorotor blowers are much more efficient than the common Eaton blowers, which are in almost all prior popular blown Fords. That was the reputation KB gained from upgrading those. The newest positive displacement blowers are comparable to the KB/Autorotor models, and some are better.

Sizing has changed a bunch in the last 15 years. Before then a 2.2 liter KB was considered large, and then KB started coming out with slightly bigger units. The 2.4 didn't last long before the 2.6 was really popular, and then the 2.8 was the monster than some people were trying out. It didn't take long for everyone to want the 2.8 and see bigger stuff on other cars. Bingo, now 3.4 to 3.8 liter blowers are not that big of deal on all kinds of OEM engines. The tuning and the late model variable valve timing, all the new technology, it has brought a lot more options to performance.

I definitely still need to come up with a better tire package, but "good" or "bad" idea... I'll be second guessing it forever. The procharger's jet engine and blowoff type noises are neat... but theres something to be said for a kenne bell whine too.

But todays development, I finally figured out what to do about my oil/trans cooler situation.
Since I went to an aftermarket radiator, the stock cooler has just been ziptied to the aftermarket cooler (which is basically under the crank pulley, with the fan blowing up).
What I decided to go with is a pair of 7x12" coolers. Passenger side will be a transmission cooler (with the fanned cooler inline behind it), and then I'll put a matching cooler in the driver's side for engine oil. Bye bye stock fog light buckets. I had plans to duct the fog locations for fresh air in the engine bay but I think I like this idea better. Not sure how much, if any of the fender liner is going to go back in the truck at this point. I've got a lot of plumbing and electrical running through the wheels wells already and this isn't going to make it "more factory" in there. haha

 

[Wagonbacker9]

Prepped for coolers and installed the new “fog lights”.

 

[Wagonbacker9]

I gotta say... sticking with my “mostly stock look” theme I’m super happy with this. You have to know what you’re looking for to catch it.

 

[CDW6212R]

I like those fog light grilles, cool.

 

[Wagonbacker9]

"grills" haha. I like that.

I do need to zip off that lower insert mount though.. thats gonna bug me.

I finally have a speedo/odo!!
