Question regarding lag.

[stolly]

OK, I don't know a lot about turbo engines yet but am endeavouring to learn, so go easy. Obviously lag is a disadvantage on a turbo engine, why hasn't anyone come up with something to get the turbo spinning sooner - something like a 12Volt electric or hydraulic motor to keep it spinning until the exhaust takes over? Feasible or not?

Thankyou

And where would the power for this come from? It would take more power from the engine than it would generate because of losses due to friction.

feasilbe - no

a jaycar or turbotech boost controller + good AM air filter + good twin dump full zorst will go a good way to reducing lag on an otherwise stock turbo car

twincharge - 5psi of boost from a roots blower as soon as your foot hits the floor goes a long way to spooling a big turbo earlier.

nos?

a supercharger, has constant psi, its like a turbo but there is no lag

[paulr33]

supercharges take power from the main belt to power themselves so you dont just get "power instantly" it takes away power to run the supercharger and adds lots more heat

Just buy an anti-lag kit lol.. keep it spooling all day long..

what about a centrifugal (sp) blower

By all reports, Nissan would disagree with you.

ddidnt they have a twin charged 'rolla of some description. Heard it worked pretty well i think it was on the levins... not sure tho :confused:

p.s. ive got some small vids of a 10 sec twin charged volvo... if anyone is curious

[krzysiu]

Sequential Turbo's?

well are we talking about one person or a company that can mass produce?

either or.

-what I was asking is that could a 12 Volt motor drive the turbo to get it spinning quicker than the exhaust can at low revs? - being 12 Volt the power to run it would come from the battery.

Yes, that is what Nissan is putting on the next GTR. Lots of good answers in here

Cool, do you know where I could find out some more info on this? I'd be curious to find out whether the motor dis-engages when the exhaust takes over (maybe a small clutch) or just free-wheels.

G'day R31Nismoid, just wondering why you were so quick to say no, can you see a problem with this that wouldn't work? Thankyou.

I guess you could use the turbo shaft as a rotor, and either pump power to it to make it spin, or suck power from it when it's making boost to charge the battery.....

Maybe.
