The Turbo Super Duty Build. (Page 30/63)
davidmgbv8 APR 30, 02:58 PM
I went to the dirt track this weekend and teenagers were driving sprint cars with Iron and Aluminum headed Super Duty engines. Naturally aspirated with mechanical fuel injection putting out 400 horse at the flywheel on the dyno. Pretty impressive stuff. Your project should really move. Can't wait till you fire it up.

you can run coil on plug ignition with megasquirt. you just have to source suitable coils.

See my post above.

Thanks!

I thought I'd let everyone know my exhaust flanges are designed. This should be final version, I've been looking around at who can machine these from 321 stainless.



One picture of a thermal load being applied:


Soo...there's some major progress being made!

Megasquirt can do DIS, but COP is MUCH more difficult. Right now it's pretty much limited to wasted spark COP, which still requires alot of modifications to set up. Even after that, you don't get individual cylinder timing control.



Cool project, I've been keeping my eye on it. Just curious, what's wrong with wasted spark? Also, what do you expect to gain from individual cylinder timing control? It seems that adding a timing wheel and going wasted spark with megasquirt would be well worth the $$$$ saved. For what it's worth (depending on your timing), when the router board is officially released later this year there should be all the hardware needed for COP without wasted spark, although I don't think anybody has talked about individual cylinder timing just yet. Also, I'm not sure what you mean by "alot of modifications" but I'm fairly confident that the Microsquirt can currently operate 4 cylinder COP in wasted spark with only a toothed wheel on the crank, which is pretty straight forward and cheap.

Just trying to help out, I would hate to see you spend a ton of money on option B without knowing the above. If you know all the above and still want to drop a few grand, to each his own of course.

I don't regard individual spark timing control as being that important. What I like is the individual cylinder fuel timing and trim control that goes with it. If I were slapping this engine together in a month or two, I wouldn't worry about trying to screw around tuning individual cylinders. But I figure that since I've spent 3 years on this already, another month spent getting it running JUST right isn't going to kill me. I'm not going to worry about it right now, so I'll see where megasquirt is in 6 months - year and go from there. If it's up to snuff then, I have absolutely NO problem spending less money. But if the quality isn't there, or the performance, then I'm not going to let it come near my baby.

Thanks for your opinion though!

That's not good...

Still haven't heard back from SPD Exhaust, who I called to have the exhaust flange laser cut. I'm not sure what the deal is with that gasket, I've been contemplating O-ringing the ports and making my own gasket.
