Default I am NO mechanic but...

I've been reading up on superchargers vs turbo. I find that sc will get you off the front line faster. And turbo is better at the high end but not as good as sc on the low end.

Has anyone ever tried to combine both? A sc to get you going that switches over to a turbo once you're up to speed?

That might be a stupid question. I'm just learning.

The concept of Twincharging has been around for ~30 years now. VW seems to be a big fan of it too. IMO, the extra cost and complexity is no where near worth it. If you need big power up top and as little lag as possible, I would think an anti-lag system would be easier.

Hybrid FTW!!!

Nothing produces torque down low better than an electric motor. Just ask the railroads. I recommend you focus on modding Priuses. Maybe a twin-turbo LS to supplement the electric motor once you're higher in the rev range.

And, if you want to add a SC like Mad Max, heck, mo' better!

Nothing says you can't also add a nuclear reactor. The Air Force did it on their NB-36 back in the '50s. Just watch out for UN sanctions.

Thanks for the link. So then, yes, it has been done. Your link goes on to say:

Quote:
Twincharging's largest benefit over anti-lag systems in race cars is its reliability. Anti-lag systems work in one of two ways: by running very rich AFR and pumping air into the exhaust to ignite the extra fuel in the exhaust manifold; or by severely retarding ignition timing to cause the combustion event to continue well after the exhaust valve has opened. Both methods involve combustion in the exhaust manifold to keep the turbine spinning, and the heat from this will shorten the life of the turbine greatly.
It also mentioned nitrous which led me to this interesting fact:

Quote:
The gas is approved for use as a food additive (also known as E942), specifically as an aerosol spray propellant. Its most common uses in this context are in aerosol whipped cream canisters, cooking sprays, and as an inert gas used to displace oxygen, to inhibit bacterial growth, when filling packages of potato chips and other similar snack foods.
So take a deep whiff next time you open a bag of potato chips. Maybe you can catch a buzz!

not as fast as you would think.... they only had to go 88mph before the flux capacitor would initiate time travel...

Yeah but going from 88 to time travel is like the Star Ship Enterprise going from impulse to warp I. In order to break the time barrier (backward) you have to exceed the speed of light. Although its theoretically possible to leave the time dimension at one point and reenter it at another by going through an alternate dimension. But that would probably require a wormhole and there's never one around when you need it.

I considered a setup using a toyota SC14 (it has a clutch like an ac compressor) I have spare and a larger turbo, but decided it was way too much effort and just got a decent size turbo lol

Take the 88 and lay the numbers on their sides. What do you have?

DOUBLE INFINITY! Know what I'm sayin?
