toda cams

[TODA AU]

i've been reading about these and i'm alittle confused

wat exactly do they mean by vtec killer toda cams? is that like running high cam 24/7?
also with spec A B and C, after installation does the rev limit rise or soemting?１

Vtec killer cams are without a high cam.
It is not like running on the high cam at all...
It is the same as running a non Vtec dohc engine, as this is what the engine becomes. It is done for reliability at extreem rpm.
(That is, one cam lobe per rocker arm, per valve. No central lobe, no centre rocker, no vtec solinoid, no vtec mechanism, no lost motion devices, no oil pressure fluctuation)

The rev limit of an engine is an engine management function. The camshafts selected has no bearing on this. Though using a TODA camshaft would allow you to extend your usable rpm range it would not give you the ability to actually do it. that is change the actual rpm limit.
