Powder coat Primed the cab so we could get as much of the tiny hard to reach inner spaces covered with the elector static powder. All under the dash and in every nook and cranny was the main goal.




Firewall mounted battery box with mounting for the Infinity Power System Power Cell and Master Fuses


Dad starting on the body work for all the little dings that couldn't be hamerd out


I'm almost finished with the frame and the time lapse. I hate MIG welding because it doesn't have the artistry of TIG and the welds will never be as good but it is much faster.



And my brother Billy has been assembling the suspension as well as helping dad with the powder coating and prep work.


More soon I should be done with the frame later tonight and we hope to blast and powder coat it this week.

Later

This has been one of those weeks where one thing lead to another and its a bit long winded to explain. So if you don't feel like reading here's the easy link to the pictures.

http://gallery.nerdrods.com/Projects/03_D3/03/


So Dad's 70th birthday is coming up and I wanted to give him something he wasn't expecting. I didn't just give him my 4:10 diff and 6 speed for no reason other than fun. I wanted to put a good power adder on it and those were necessary if they were to survive. So I got him an LSA supercharger thanks to their falling prices. I pick this guy up for less than a grand with the adapter plates so they would work on the cathedral port heads.



And we obviously need to make sure it fit the firewall before we went to far with the project. This is with my Vintage Air Pulley system and LS1 Camaro Oil Pan on the motor from the old PT-57. We just wanted to drop it in the frame and make sure it all worked out.




With that confirmed the frame was ready for powder coat. Dad was getting busy slamming the chassis together after it came out of the oven.








We've also been saving a set of the big 13" brakes for one of our projects.

So some of you follow us on the Facetubes or Twitter and those guys get a bit more of an update since I can just snap a photos and stab it to the net nice and quick. One of my customers saw the supercharger and we started talking. He had an STS Single turbo for his project but the super charger will actually make his life easier. I was still trying to work out an affordable pulley system (www.lssimple.net is what I was looking at BTW) and the fuel rail is an additional cost I wasn't looking forward to either since the LSA has a very unique system thanks to its pocketed fuel injectors and I was going to need some real headers to keep from choking the motor. So I asked if he wanted to trade. He said yes. (insert evil laugh)



So that got me thinking "Well we'll need a turbo cam and so I'll need to pull that one out of my 6.0L in the corner from the PT-57 and then take off its pulleys and move all that over to Dad's 5.3.......... OR, I could be lazy and just put the 6.0L in his truck." And so thanks to my laziness dad now has a 6.0L LQ4 with single turbo for his truck. Should be in the 550HP range really easily. That motor with twins and the same gear ratios did well over 567RWHP on the dyno a few years back so this should be a cake walk.



The motor goes in the chassis this afternoon. More to come ASAP.

So as you might have seen in the video the chassis is together and the motor and transmission are both in.



Dad got the radiator should made up to fit out generic Griffin Radiator (188.17 Part # 1-25201-X) The PRC Condenser Core ( 120.00 after shipping, its not on their site so you have to call them about it ), and some cheap summit fans (85.94 Summit Racing Cooling Fans, Quantity 2, Part # SUM-G4901 42.97 Each) I updated all this on the first page for the totals as well for people keeping up with pricing. Made up a few tabs to hold it to the stock core support and not I just need to weld it all up.







Body work continues, he keeps finding "just one more thing"..... I was afraid of this. And so Dad's Down and Dirty just became Dad's Down and Dangerous. We'll see how much longer he keeps up at it but I think its going to end up pretty darn nice when he's finished.




The hard lines are going down and we are getting the turbo system layout worked out as well. Should look something like this but with 2.5" off the headers into a 3" into the turbo. Then 3" out of the turbo into a dual 2.5" out the back.






Things will slow down for a bit while we get the body work wrapped up and we get 2 customer chassis's wrapped up and shipped out.

So it turns out this was part of the turbo trade since he won't need it any longer. Man that high rise and 105mm TB look mean on there. Jim also mocked up the inner fenders to get them cut down at the bottom to clear the A frames and suspension.



We're also looking at room for the turbo piping and other clearances on both sides of the engine. Thinking about a liquid to air intercooler as well as some other goodies under here. Mostly AC and Heater lines and dust protection from the environment. I'd like to keep it clean under the hood as best as possible.



We're looking at room for the crank case breather and air oil separation as well in this setup. This is something I feel like so many people overlook so here's some math to help you think about it and to keep in mind when doing your breathers. This is a 6.0L (366 CID) motor, with peak 7 PSI of boost we will effectively have a 9.0L (549 CID) motor making 100% aspiration. Now think about the rings. They seal good but not that good. If you do a leak down test you can see 10-20% blow by on the rings and that's still acceptable for a motor to be able to run down the road. Top of the line, super fresh, racing motors might be able to hold all but 5% in the cylinder (Start a debate about this somewhere else if you want but not here). So for the sake of argument this used truck motor will leak 10% of its air into the crank case. Let me show you how much air that is.

7000 RPM's Red Line
6.0L Displacement @ 7 psi boost is about 9.0L
10% blow by

(7000 RPM's / 2) * 9.0 Liters = (31500) Liters of Air per Minute.
28.3162 Liters = 1 Cubic Foot
31500 LPM / 28.3162 CF = 1112.414 CFM Cubic Feet a Minute
1112.414 CFM * .1 (10% blow by) = 111.2414 CFM Blowing into the crank case
111.2414 CFM / 60 Seconds = 18.5402 CFS

18 cubic feet of air a second blowing past the rings and into the crank case. That's a 3'x3'x2' box of air, EVERY SECOND!

All of that has to go thorough those two little 3/8's AN-6 hoses on top of the valve covers that are pressed on their barbs by hand I might add. Back pressure galore slowing down your pistons! So we're adding AN-8 weld on bungs to the valve covers and one, possibly two, lines to the valley cover to get the air out of the crank case so the pistons will have as little resistance as possible going down. If this were an emission car I would vent the oil catch can to the front of the turbo so it could suck down the fumes but that's a long stinking way for this project so we're just going with the breather on the catch can for this one.

Amazon Find!


You just have to drain it when you change your oil.


On the body work front we keep finding little things like these two cracks in the metal. But Jim's chipping away at it and working on mounts for the Infinity box wiring as well as the creature comforters.



And the money shot!

Wow, time for a very long overdue update. Iíve been caught doing a boat load of paperwork and the new year / holiday season decided to catch us off guard but while Iíve not been posting we have not been idle.

Gallery photos all here if you just want to look at the pretty pictures
http://gallery.nerdrods.com/Projects/03_D3/04/


So most of this started with two things. The intake tubing because of the turbo intake and the high pressure zone Jim kept wanting to use as a vent. The pressure at the cowl might have had a tiny effect but Iím 90% sure after reading up and getting some education for you guys on the forums that if there was any heat loss it would be minor to nonexistent. So I finally found a few videos that convinced Jim of the same thing. So it was decided that this cowl vent would be used to feed the turbo under the passenger butt.


Next we decided to check for tire clearance, now that the truck would be considerably faster we wanted to make absolutely sure that we could get some larger tires on here later if we wanted to. So the worst point is full compression under full lock of turning. The spring came off and the tire went on. As you can see we found out the inner fender was going to be a problem.




Perfect time to make something cooler and more suited to the firewall and so the custom inner fenders began. At first we planned to just modify the old ones until it became obvious to dad that making new ones would be much easier.

They turned out pretty epic if I do say so myself. We are talking about molding a set to make fiberglass versions later on or maybe some jigs for steel versions, weíll see.
