What about 2 small engines? Primary with all the periferals and a second for when you want or need to add more power.

i remember a 1st gen insight with an electric drive scooter wheel added. it had its own battery pack and controls, it could kick down for really low speed traffic, drive through situations. etc. while the gas engine remained off.

for highway speed, if you are going to idle the big motor anyway, i would just put in a crazy tall overdrive run as low rpm as possible for best mpg, or find a way to run the v8 on just 4 cyl. or less

THIS

This is what I mean right here, in city low speed driving to take advantage of the fact the small engine is small, I can't do cylinder deactivation on my main engine but I can probably put an even more extreme OD unit in, my current one is set to kick in at 40 mph and engine then goes to 900 rpm and at my normal top speed (65) it only turning at 1550rpm

Well I would consider this if not for two problems, I just spent about 20k on building an engine for this truck and redoing the suspension and drive-line and I kinda want to keep my new stroker lol! The second problem is that I want to have massive amounts of power on demand and I can't think of two small engines that can do this as well as my primary one, hence why I'm thinking of just adding a small 2ndary drive for in city traffic

How about converting the V8 to 2wheel, rear drive and take advantage of the off-set yolk on the front axle to run a rear drive 4cyl backward for 2 wheel, front drive. Best I can think, this is the simplest way of doing things but would require major modifications to the truck bed and rear frame to make room and support for the all new power train. Maybe come up with a way for both engines to use the same radiator/share coolant so that you can cut down on "extra" hardware.

Kinda don't want to lose 4wd, I was thinking add in another T-case near the rear and splitting the driveshaft in half and have it set up in a disconnecting style so It can be electronically decoupled from the V8. As far as mounting I was thinking a drop-in cage like thing in the bed with quick disconnects and stuff, as far as cooling I think a small rad with a clutch fan or even an air cooled engine might work

I've always liked the idea of taking a FWD car/ pickup, say, a Dodge Rampage andputting a second engine/transaxle in the back.

The rear/mid engine would be tweaked for some crazy high hp to the point of being undrivable on the street. The stock front engine would then be just some little sub 1.3litre for tooling around in traffic.

Of course, nowadays it would make sense to put an electric motor in the front, much like the newest generation of supercars.

Are you talking about this thread? http://ecomodder.com/forum/showthrea...uck-30845.html I feel like the hybrid route using an electric motor and battery would be better, especially if the low power motor will be used mainly close to home. Why not have the big engine just turn off when its not in use? The small engine could easily handle the accessory load while burning less extra fuel than the big engine idling.

Yes that is the tread that give me the idea, how would I keep all the electrical system online though if the main engine is off? Nothing would work electrically if its off.....and I agree that the large engine would absolutely drink gas at idle (It mean it makes over 400 TQ and near 300hp off idle lol!) Oh and if you think that a pure electric secondary system is better please say so
