Ridiculous 1000HP 7M Street MK3 Build

[Beals]

Beals - the amazon tig runs on 110 and 220V. My shop is already setup on 220V for my dads miller mig machine.

I suppose so, but when I think of a welder mig or tig I think of big wire wheels not the teeny toy's you can get for little things. For small stuff they really are handy but why risk blowing breakers and halting projects when it doesn't cost much more to do it right.

That's why we use 220 3-phase

The building actually has 256volts but has to be brought down as the machines don't like much more than 206 and it has to be a very clean signal.


You should of seen the guys face when we requested a 60kw/hr transformer for one building when the entire street was being run off a 20kw/hr transformer.

Unless u are welding huge steel pipes or ship hulls and truck frames 220 is more than enough for race car fab work. Havent needed more than 120 amps yet and I've gone through a few projects.

I didn't know you name so I just put your screen-name. Wanted to see if you wanted to chime in here.

I'm curious how you like that TIG so far? How thick of aluminum can you weld with that?

The tig is really nice. More than I need.

In other news - I got all my crap back from engine lab.

Here is what my $500 bought me. The race balance took out about 80% of the force generated at 9k revs.

What does this mean in "layman's" terms?

 

[NegativeGeForce]

In layman's terms - The crank is gonna twist and wobble less at high revs.

The initial spin compares the crank before doing the balance and the final spin is after they have balanced it.

The stock crank had nearly 70lb of force generated on one end of the crankshaft at 9k and there was a huge difference between the left side and right side of the crank.

After the balance the difference between the left and right sides is much much closer.

This was done to the stock full counter weighted 7M crank using much lighter forged pauter rods and JE pistons.

are my eyes imagining things or is your camera playing tricks? everything has a banana curve...

looks real tight....

 

[NegativeGeForce]

panographic feature on my camera warps the image like that...

Whats pictured so far is only about 1/3 of my stash. If I actually unboxed everything I wouldn't have space to work on the car, lol.

hmmmz so guess that claims that Rich said about milbrum using his crank girdle was all bollocks.

could have made it even simpler and said I got it balanced just saying lol but it's neat they gave ya a card from before and after

 

[Grandavi]

Lol, but he actually taught me something. My crank was balanced but I didn't get a sheet like that. Had I known that existed I would have demanded one.

 

[NegativeGeForce]

Problem is other shops and people say it doesnt need balancing cuz an inline 6 is inheritly balanced but they would be right and wrong so instead of posting hearsay and opinions I thought id explain why and post proof that shows there is a benefit in my case with lighter forged parts. I am sure with stock components the balance wouldn't be as far off but still would benefit.

I would say though for a stock rebuild the race balance is overkill when the balancing costs almost as much as stock rebuild parts. It only makes sense if your changing alot of parts around and trying to go for high revs and hp. Engine lab does offer alot cheaper basic balancing though that won't be as precise.


I'll take some close up pics of my crank but it looks almost ravaged with the amount of grinding they did on various parts of the crank to obtain the balance and they also took weight off my flex plate.

Well with only the words "polished and balanced crank" and no balance ticket... Balancing on mine could have been setting it on a bench and saying... "Looks good to me"

 

[NashMan]

Most shops will balance the crank it's not cheap

Most shop will have paper work if there muchine does a type out

for example this time around it's getting balanced with out the balancer and fly wheel since I may change them down the road and don't want it to effect my motor

 

[NegativeGeForce]

$300 in fittings, drill bits and taps later...

 

[IJ.]

Need to chamfer that hole

 

[NegativeGeForce]

Yea I'll hit it with a file or something...
