Strapping a turbo onto it would create way more power than really necessary (though it would be fun to try), and even hybridization would have limited benefit outside of low RPM operation, where I predict the engine will end up coming up short.

Sure it would seem quite pointless at first, unless you were willing to build some sort of KERS.

I would like to build a hybrid system into something similar to Honda’s IMA system, whereas the motor works alongside the engine, and helps with engine braking as well as acceleration. That seems to me a long ways out though.

I figure with the turbo and the head work I could probably safely get to around 250whp without glaring risk of engine failure, which would be fun in a sub 2500lb car. Adding a hybrid system could potentially increase system output to ~275-280whp?

The setup of some European-designed hybrid trucks and buses is somewhat like an improved IMA. Look for that ZF hybrid "modular" motor for trucks and buses and you'll know what I mean.

Presumably you could get an even higher combined power if that was the case.

I was referring to total system output with hybrid and turbo. I’m only even hoping to add maybe 25-30hp worth of electric propulsion to the car, I’m not sure how much more I could add via a belt drive

IIRC the EQ-Boost system fitted to some Mercedes-Benz cars delivers 14hp.


On a sidenote, look at this Corsa with some (unproperly done) weatherstripping around the top of the windscreen. The tape used in this one is not suitable to painting over it.

That looks just like standard duct tape, which doesn’t take paint so well.

I figured that the supercharger on the Ion redline can suck as much as 30hp when it’s pullied down for more boost, so in theory the belt can transmit about that much power? Then again that’s not counting for the big spike in low end torque provided by the motor. It would be worth trying I think

GM eAssist put and takes 14-15 HP through a toothed serpentine belt. Replaces alternator and starter but requires battery pack and controller. Enables regen.

The belt for a supercharger is usually wider than the accessory belt, so it might be better at transmitting a higher output than the regular-sized accessory belts fitted to most BAS-Hybrid setups.

[Piotrsko]

A roots belt is not only wider (2") but is cogged and has matching cogged pullies. At the rocket site, we used roots blowers as a high volume low vacuum roughing pump for the test chambers and were operated by 50 hp electric motors

[19bonestock88]

Speaking from experience, the belt for the factory roots blower on the supercharged Saturns is not a cogged belt, though it is wider than the one my engine uses, which would necessitate the wider harmonic balancer and alternator pulley from the LSJ (I think I have those still in storage). At current belt routing I can most likely either place the motor in place of the AC compressor and use a stock belt, or figure out the stuff from the 2.4 hybrid BAS system
