🔧 BUILD PJ’s bad idea - notch edition

[PJx5x]

Your work always looks great but don't let it get to your head.

What clamp are you using between the pipe and TB? Race Parts Solutions?

I’m happy with the work I just absolutely hate pie cuts and everyone that uses them

Yea they’re used RPS clamps from the old wrecked gray car. I cut em off and cleaned up on the lathe and ordered new orings

I have tight 4 or 5 br .075 3dia 304ss 90s in my backyard still.

I think I've used all of em that I'm gonna on the TR, 442 and waGN

My truck I've got a crapload of 3.5dia 304 mandrel 90s

That’s 5” stainless. Aluminum 5” 1D bends are impossible to find right now so I had to make do

 

[Turbocharged400sbc]

I have 6" aluminum...


....1/8" wall straight only

Pie cuts and no weight savings lol

 

[Pro Stock John]

I could be buyer for 5" stainless if folks have bends and some straight runs

 

[Turbocharged400sbc]

You missed the 1. In front of that 5

 

[PJx5x]

Downpipe back purged and welded. Forgot how much I hate stainless. Figured I’d knock out the exhaust back pressure damper while I was at it too.

Now to see if there’s room to turn the wastegates and dump them under the mini bullhorn. Rather not have them in line with the tires

 

[Turbocharged400sbc]

Yeah not oiling down yer tires is deff desirable

It's amazing how often I see those super deep o2 bungs in spots other than the inside of bends....shouldn't hurt 5inch but it's a tree stump in the middle of a waterside for those of us with less girth.

No lathe at home to turn it down and I’m off till Xmas so I just sent it. I’m actively not being OCD and just putting shit together. It’s weird for me lol

 

[RedBeard]

What’s the exhaust back pressure dampers propose? Never heard of that.

 

[Turbocharged400sbc]

Dampen pressure pulse spikes to clean up transducer output/signal.

Usually a small orifice to a chamber that the sensor references

 

[PJx5x]

Yes and with a coil of tubing to hopefully remove some of the heat so you don’t kill the sensor

 

[Pro Stock John]

what are you doing for overflows

 

[sktchy]

Idk where I've been but this looks like it's going to be fun.

 

[Turbocharged400sbc]

Is the turbo a vnt unit and its controller works via drive delta for position? Or is this just for datalogging?

 

[PJx5x]

what are you doing for overflows

future me problem. Radiator is going under the trunk floor so I assume a tank in the trunk

Oil will go wherever I can fit something. I’d like to hide in cowl but will probably take lazy route behind passenger shock tower

Trans I’ll just bolt something to the case

God no lol, this is some China knockoff Borg Warner Turbo. Just for datalogging

 

[PJx5x]

Wastegate dumps made and mounted. Will get a black aluminum trim plate to fill the gap to the bumper

Got the radiator shroud all cut and bent up at my buddies shop. Just tacked it together and figured I’d take a pic before I boogered all the welds

Dual 16” ish Silverado fans. PWM capable. Will be controlled separately via ECU. If I did it over again I might consider doing a single 19” Camaro fan so I only had to use 1 output from my peasant ECU

 

[PJx5x]

16 feet of welding later. Thank god for water cooler and pulse

 

[PJx5x]

Started modifying the oil pan while I wait for some tabs and fittings to come in to mount the radiator

My steering rack is in front of the engine so I might as well take advantage and run a full sump oil pan to have as much capacity as possible. The only full sump pans out there are super deep (marine use I think) and I’m too cheap to pay for a $1k custom one. So I’m going to modify a corvette pan, the shallowest available.

This is for drag racing, not road racing so I am going to move the pickup back into the rear quarter. And cut windows in the baffles (green sharpie) to help feed it. I couldn’t figure out a way to cut those out nicely so I milled them through the bottom and will have to plug the holes I made

I also cut out 1/2 of the slots to feed the sump extension I’ll be welding on the front

Made a short CNC program to make these slots in a straight line with a 1/2” mill so I could easily fill them in with 1/2” bar stock. Worked perfect

 

[Turbocharged400sbc]

I would have loaned ya a t slot cutter
At least being new casting it should weld good.

Sump extensions like that fairly common?

I’ve seen a few. However most people with budget LS shit don’t have stilleto steering racks and front suspension where you have full pan access lol

 

[PJx5x]

Got the oil pan done. Tmrw I plan to start modifying the pickup tube to fit in the back section of the pan

Buddy made me a ORB bung that was extended so I could weld it from the inside. I was worried about welding the outside that close to the flange and warping it or something

Then leak tested the assembled fuel tank at 2 psi shop air and sprayed soapy water all over. Found a little leak from where I stop/started a weld and had a crater

Then made some mounts for it out of beefy extruded angle. Figure this is better than bending tabs. Will most likely put some rubber washers under them and drill the holes out 1 size. Don’t know if that’ll actually help anything from cracking or not when the chassis flexes

 

[Turbocharged400sbc]

If ya need to borrow a quick spritz of spot checker for the pan lemme know.

Double check but I think any bushings need through sleeves for the rulebook?

What kind of spot checker?

I’m not getting sleeves for a 1/8” rubber washer lol
