www.hairyglass.com makes a few for fwd dodges, all3 gen daytonas, omni/charger and lebaron. they dont make a shadow kit and making your own unique mold has to be more satisfying.

Brian, mains doing well for you so far?

What power per PSI are you estimating it's doing given a set AFR?

"If I wore a hat it would definately be off to you and the quality of your build. It gives me inspiration in my own work."

Thanks! I am glad that I can start to finally enjoy all the work and time to build it.

"Brian, mains doing well for you so far?"

Oh yeah! They help with keeping peace of mind as well

"What power per PSI are you estimating it's doing given a set AFR?"

Hmm, if I take what it made with no boost vs. with boost, it works out to be 27. I was thinking low 20's, but I should have a better idea on Thursday.

Thanks for thinking and doing outside of any box you can think of. Awesome work, and dedication to the hobby. What do you do for work when you are not shaming all of us into working on our rides?

" but I should have a better idea on Thursday."

Thursday was yesterday... Any updates? Additionally, Keep up the GREAT work!

I am a mechanic. My father and I own a repair shop in Phila.

"Thursday was yesterday... Any updates? Additionally, Keep up the GREAT work!"

A small update, took the car on Thursday. First pull, the intercooler pipe split where I had the bov mounted. The bov has seen its last day on my car. Also, the balancer slipped, looks like it spun 15 degrees retarted. Since this is also a mount for my crank trigger, the timing was thrown off as well. Time to put a keyway in there(I think JT had a similar issue). So a few more bugs will be worked out and I should head back around mid week.

Crikey Brian! How much boost does it take to split an aluminum IC pipe? I know you can weld...

Funny thing, a lot of factors can come into play with that. I made a wicked 4 core W-A intercooler for a special project at work and the endtank had a weld split on it at only 6 psi. Obviously that's not normal since I make all of the other intercoolers at work as well.

Turns out that the direction of the air coming through the core and how it hit the end tank seemed to be allowing the rather wide (20 3/8") facing flex at the two weld points causing it to fatigue and crack. That sucked.

[turbo2point2]

Like Aaron said, it doesn't take much, in my case it was 11 psi. I think there is more to it though. Last time on the dyno the tires were causing some pretty rough vibrations. I don't think it was weld quality, I feel a combination of the bov on the outside of a mandrel bend, harsh vibrations and virtually no movement allowed(no silicone connectors) on that pipe made for a easy break. I will get a pic of it today.

[Dave]

Pics?

[turbo2point2]

Pics?

Here ya go!

Ah yes, the same kinda break I had on my Aluminum sheet metal intake. Each spot where the fuel rail boss was welded just 'popped' out, left me with two quarter sized holes I think it has something to do with the heat affected zone next to the weld... Been too long since that Jr College Metalurgy class

Sexy welds BTW Brian

The vibrations couldn't help either. Probably a combination of a lot of factors.

[Clay]

yeah, elbow probalby isnt the best place for that BOV. Concentrates more pressure on the outside of the turn. With the extra volume right there, ie pocket, it probalby makes a high pressure area right under the BOV due to the bend.

[BadAssPerformance]

^^^ that and the fact that the metal on the outside of a bend is stretched thin and stressed so the welded area is annealed and the area next to the weld was still stressed so it is kinda brittle.

[turbo2point2]

"Sexy welds BTW Brian"

Thanks Alan.

Im sure it was a combination of things that lead to its failure, but I can say that the bov can not break off now

Just don't run one.

[Dave]

Just don't run one.

Is that how you do it on your twin turbo lambos?

[8valves]

Nope, they run twin TiAL 50's.

With Lee's "big" twin car (twin 90mm's) we don't run one though. Just a chance for failure in reality. With a race car that sees some street duty from time to time, with an auto especially, we deemed it not necessary.

I would think Brian's could get away without one as well. A little compressor surge out of the burnout box makes for some serious intimidation at the beams too

I removed it permanently from the car. I am sure it will be fine without it. I may try and get to the dyno before the weekend is over. Gotta get it done, the baby is almost here!
