Let the plumbing begin

Good idea, I use one of those router control things on my big electric die grinder, I was thinking of getting one of the HF 14" 2hp chopsaws and seeing if I can dial back the speed a little to make clean cuts.

Ditto. I've got the $100.00 + Makita 1/4" Chuck die grinder. They wanted over $200 for the one with the variable speed built in (Although I think it adjusts current to maintain torque/speed) so I just used a router controller. I use it with the router as well. Never tried it with my Chop Saw though. I'll have to try that. But for porting heads, etc it works great with the Makita. Even at very slow speeds it still has enough torque for the carbide bur's to cut into a head.

Parts are starting to dribble in for all the plumbing etc, I was hoping to have them all before the weekend but that is looking unlikely.

Whats the deal with those 3" ?? Finned aluminum tubes. Looks like you have a pic of one mounted post intercooler going toward the front of the car? Seems like way to much air mass flowing through to act like an intercooler.

Maybe to keep the heat from the exhaust from transferring up the intake piping and heat-soaking the intercooler?

I have 2 of them at 2.5" between the turbo outlet and the intercom lee to act as a per inter cooler heat soak, figured it can't hurt and I've been gagging to try them for ages. I bought one in 3" as well while I was drunk parts ordering and put it in post inter cooler to again act as a heat sink , figured it can't hurt there either. I will add some internal cross ribs to help transfer heat out of the charge air into the extrusion too.

You'd be amazed at how much heat those can actually extract, especially being exposed to so much airflow under the car. I thought that with the air moving so fast in a pipe there wouldn't be much heat transfer either... until I did some calculations on it.

Here's a bit more of the setup.

You're a sick man. I can appreciate that.

all thats left is a blower

Not so fast, there is still room in the trunk for NOS!

Wow..... just wow.

Until you put couple thermo probes before and after those heat sink tubes, will you really know how effective they are?? Personally I can't imagine them cooling the air that flows through there so fast...and then, it's only the outter boundary of the flow that's affected. It'd be interesting to know...you have some data logger, right? Hook it up!

I know the turbos are cheap but I think you'll pick up waaay too much crap with filters just there. Perhaps not - what are others with similar setups doing?

Oh, and is it done yet?

Yeah this is all a big expensive experiment. I am learning a lot already and it hasnt even been fired up yet.

My plan is to slip thermocouples into the intake plumbing at several locations and record some data to see what is actually happening, should be interesting to find out.

On the filters, they will get put into an aluminum box enclosure that pulls air from the top rear side to help minimize dirt/water/kitten ingress. Most of the LS guys who do this just use air filter socks to keep crap off the air filter, which I will probably also do.

 

[pkw]

cant you just route the filters behind the bumper cover or do some cutting and get them up in between wheel well area and outer fender?

Be careful what you assume... The air in those pipes is in turbulent flo . Thus there might be better heat transfer than you'd think. Of course for small sections of pipe it isn't going to be much, but I think youd see at least 10 degrees Fahrenheit if the lengt From front to back of the car was finned. Of course it all depends on ambient temps and such too. I'd do some calculations but I'm too busy at the moment.

 

[pkw]

are we really having this talk? probably best to assume the ic will do the ic job and pipes are pipes. : ) waaaaay cool car btw. It is going to be fast and just plain frickin cool as heck!

 

[rathergoodaudis]

lol@ kitten ingress.

This engine RUNS on kittens. Or sliced dolphins in a pinch.

Apparently we are. ;-) Either way, I'll be curious to see what the temp probes say. I agree that if the entire length were finned it would have a significant drop, but they are so short. And with the heat from the Turbo's / Exhaust, I almost wonder if they wont pick up some heat unless the box that he builds for the IC also separates the finned tubes from the exhaust.

Either way, will be interesting to see the data from the probes.
And the data from the other fun stuff...... Like the Dyno

Alright it's time for an update.

Lots of stuff arrived so I could start the major plumbing. I hired Ryan of Higbee Fabrication for the day to helper put a dent in the todo list. Ryan did amazing work as he always does!

Task 1: 4" down pipe and front crossover merge from the passenger bank.

Reverse from the passenger bank to the x over pipe

Front end exhaust all ready for final welding. 4" DP is MASSIVE!

Start of 4" exhaust (3" bend for size reference)

 

[timmmy]

We also got most of the back end 'cold plumbing wrapped up.

So now a little finish welding up front and its down to building the exhaust pipe and rear split pipe to feed the turbos, and the charge tube from the rear subframe to the throttle body, and major fab is complete
