Never before has so little power been made from so much displacement! (Page 11 of 57)

So true.  It's one of the theads I look forward to seeing every day.  This truely is epic and needs the recognition.

Not to be a debbie-downer, but how are you gonna NOT bottom out when suspension is under full compression?

there's a little over 3" under there. the shocks can only move about 3.5" before they reach full stuff. i doubt I'll ever hit full stuff on both sides at the same time.

my road going MR2 only has 4.5" clearance under the same area and i never hit anything. a road course is significantly smoother than a road around here.

Maybe just get taller bump stops?

Simplest solution:  Skid plate.

If things are kept the same and you do put a skid plate on, and you do scrape once in a while, can you run a night race so we can get picks of the rooster tail of sparks? 

Just a thought: if you can get an R6 or an R1 throttle body set, I have extra TB's (less than five, unfortunately) of both, and I can build you a Megasquirt to FI it all. R1 can easily make over 200hp on stock injectors, so you'd be covered at least up to 250hp, and injector selection is there if you want more. Allows you to use the stock tank, pump, and return system as-is, too.

Adding a turbo (or five) would be a breeze from there on, at least in terms of fueling the thing.

How's ignition, by the way?

I'm optimistic he'll get the engine running.  So I was pointing out something that he probably had already spent countless hours thinking about. 

I'm pretty useless in that way.

We're here to cheer ya' on man!

the plan right now is swinging towards EFI, I haven't thought much about 5 throttle bodies versus 1 and how to mount the injectors. if you have those motorcycle throttle bodies with fuel injector mounts already on them, it would be fantastic! i sent you an e-mail.

i would love to do a shady EFI, but i may be running out of time and just have to do a vanilla megasquirt.

one thing i need to figure out is if i can use a waste spark coil to actuate both plugs in a single cylinder. i think there's no reason it would not work, but i'm not 100% sure. normally one plug has a lower breakdown voltage because it has a compressed air charge in it. maybe i can use a different gap on both plugs to start the flame front in a predictable manner each time. using a 4 cylinder and 6 cylinder Ford EDIS module would be much cheaper than 10 individual coils.

as for the "it doesn't run yet" comment. i have opened the motor and fully dissembled, fixed and resembled it. i know the motor is good, the cylinders have low~ish leak-down numbers. certainly enough to get good compression. fuel and spark will be fully custom since i'm not using the stock provisions so we aren't talking about a high risk that may or may not show up. i *know* that i need to make these custom things.

the only hard part in this whole equation is the insane timeline.

i already have two audi I5 vacuum/mechanical advanced distributors that i was going to use with the original carburetor setup.

yeah, it's definitely got a lemon flavour to this project

before starting work on the car tonight i figured i'd get a few daytime pics:

sorry i did not pull it out entirely, it became apparent after a few feet of movement that the rear toe isn't as perfect as i'd like it to be. any further and the ice would have prevented me from pushing it back in the shop.

and here's one with a scale of the clearance. the piece of wood on the ground is a 4x4 post and it *almost* fits under the crossmember

off to the shop i go for now!

how about another update. i've got half-shafts!

i even documented the whole thing because i figured someone would ask how i made them.

1) cut shaft to right length

2) machine a taper on the edge and a centered hole for a dowel pin, 10thou under or so.

3) use a shit-ton of pressure to smash it all together

4) admire the new shafts

5) setup the shaft in the rotary welder and pre-heat the shaft a bit

6) weld the first pass

7) using the press and an indicator, straighten shaft

8) finish welding and sand-blast the weld to clean it up a bit

9)put together the chinese frustration puzzle

10) tada!

and then, if the math was right, it even all fits!

i still need to place about a dozen fasteners to hold everything in place, but the half-shafts are done.
