Ok time to sign up and guess the horsepower on the dyno

Holeshot

Where are the EGT bungs that we should be seeing on the headers??? How can anybody tune an engine on a dyno without an EGT reading for each cylinder???

Here's what the boat exhausts look like when installed backwards to be used as liquid-cooled twin-turbo exhaust manifolds...

I'd bet that there is a liquid-cooled motocrosser head gasket that would fit the output flange.
As is, these manifolds have a hose in & a hose out, so all I need is a couple of heater cores with small fans to cool the exhaust.

Gregs got to weld some bungs in yet, although I'm researching if the EGT probes I use in my aircraft engines will work. They only require a .156 hole and are held in with a radiator clamp.
They are a type "K" probe.

I'm really not fond of having to cut a bung out and reweld the header tubes after the run.

Why not leave the bungs in & plug them with a pipe plug? The ones I got from Summit weld on then you remove the plug & run a next-size-smaller drill bit thru the hole & thru the header. Just install the plugs after the dyno time. Then the EGT ports will still be available if you ever get an onboard data monitoring solution. Thay are getting cheaper all the time. I'm about to start programming my own setup (VS C++) & use an el-cheapo laptop pc to install above the driveshaft tunnel.

Another thought: When I was working at a Yamaha dealership back in the 80s, Yamaha sold a "riv-nut" type bung to install in exhaust headers for their EGA machine to attach to. As I recall, it was about a 7mm hole to drill & use their crimping pliers to crimp the bung into the pipe. Then there was a 6mm bolt you could remove from the bung to stick the EGA port adapter into. No weldin, no leaking, though I would use some type of high-temp sealant when installing in a high HP AM engine.

Lets change the title of this thread to "When" will the engine get dyno'd 8)

Whens Pat going to get the 360 going and in the jeep..... and then if i missed my motor mounts getting some use whens he going to dyno it? 8)

Talked to Greg yesterday, he had to get some other info about the injector system and the Fast driving the injectors I had to Call craig at BDS so bottom line for right now...
Saturday we turn the key!!!!!!!!!!!!!

Stay tuned.........

As a side note after I chatted with Greg and Craig Railsbeck at BDS I got to thinking about when this whole project started. I looked back at my notes and I had dragged the donor Wagoneer home on April 28, 2003 to start removing the running gear. It's been 3 1/2 years seems like a eternity. Actually I think the easy part was picking the cam, making all the calculations for piston to head, machining all the block and heads, etc... As a side note I know alot of folks are really anxious I am too. What I am doing here is taking a mid 1970's engine and controlling it with state of the art technology. I myself haven't seen a 401 this highly modified, run by electrons. Has anyone else? I'm just a analog guy living in a digital world. Jeff

the engine in my 69 is a complete efi system . it has coil on plug ign. a crank wheel and a cam sensor . a 2 bar map sensor and air, fuel pressure ,water temp , nitrous pressure , egts, and dual 02's . the computer controls the trany break ,fuel pump ,water pump,and the nitrous .But I still hit the gas and shift the trany because it was starting to get boreing raceing when all I had to do was point the thing :razz: :razz: :razz: :razz: :razz:

After FINALLY getting a chance to spend some time with MY Jeep for a change, the Heart of the Beast kicked over today - several times :wink:

Damn I love it when a plan finally comes together!!! Straight pipes, no muffler, the Heart throbbed and I vibrated :t: Had a woody and damn near had a religious experiance :!:

When I can finally drive it out of the shop, I may have a cardiac!! =D>

Pat I just called..!! Congrats on adding 110 more cubes and 2 more cylinders!!
SOUNDED AWESOME..!!!

The first call was like a comedy routine though :?:

What is the brand of the ECU?

Jeff

You would have thought i would have seen that one but then again your supposed to be better at keeping us all informed. howcome the thread died so soon. jeesh this ones at 10 pages a 360 build / swap should have at least grabbed 4 pages

Holeshot

welll im sure as heck not going to get a break in the next 13 months :(:

I am useing the AEM ECU
http://www.aempower.com/ViewCategory.aspx?CategoryID=63
I had a fast unit but I sold it for this one.much better then the old fast unit.I played with a Fast xfi unit a little on the dyno with a sb chevy it was better but I like the AEM for the data logging and the ease of tuning .I am spraying 400 hp nitrous dry with this system and the car runs like a bracket car.

Anybody else notice that Jeff didn't say WHICH Saturday???

I think this is getting to be like that sign I saw once that said "FREE GAS TOMORROW", ha, ha.:mrgreen:

BREK

I can't take it anymore! I think I'm going home and having a few :razz: :razz: :razz:
