Thread: Any reason NOT to go twin

a thread you started?

it says it was stated by "dagger"...

yeah, no original post. weird.

efficiency is a good reason not to.

How about for the same money just turbo it and go twice as fast?

From the research Ive done its a tuning nightmare..and what blue was saying instead of having a tuning nightmare go with just a turbo and have more power than both.

once the turbo really starts to spin, the supercharger will just get in its way.

with the stalls/torque converters avalable you are pretty much in high rpm every time you step down on it.

Twin-charge is the way to go on the street. For the track, turbo is probably better, although zzp built a twin-charge car that ran 9.9, so I think we can rule out the assumption that the supercharger is somehow creating a limit for the turbo.

The biggest advantages to twin-charging is that the turbo can be sized much larger to create better top-end boosting while still maintaining plenty of low-end torque with zero lag. This is most advantageous on the street where you are driving in many different rpm ranges and want instant power. I really like the feeling of the instant power in every gear and speed. Swapping smaller pulleys on a twin-charge setup creates even more street power, but sacrifices the top-end limits because of the stack effect.

Twin-charging will create more heat, as the boost still tends to "stack" even after the bypass is active. This stacking is what gets the boost up to full much faster, but the additional heat must be dealt with, which is why it is recommended to have a twin-intercooler setup installed.

There are not very many twin-charge setups, so I don't know who started the rumor that it is difficult to tune. It is no more difficult, or even different, then tuning a larger turbo-only setup. Boost comes in earlier, so PE vs. TPS is adjusted to handle that, but other than that, it is basics.

Pfft. Holset's are junk. Stick with Garret or Turbonetics.

garrets are expensive for what they are.

curious, with the stall in this video, would it not elminate the low end lag/spooling of the turbo?? keeping the rpms high at all times when your in it no matter what speed your at. would you still need to twin charge with a set up like this??

well a supercharger is pretty easy to obtain.....

i was kinda looking to a little more pros and cons to the diffrent set ups.

i really dont see how the supercharger would not get in the way of the turbo, but thats why im here, to learn.
