Curiosity ONLY...No plans to do this...

What would be the result, if the TRD Supercharger was running in tandem with a turbo kit??

Supercharger getting the air tube first...then running through the turbo...

Would this be stupid? or would it actually do something beneficial??

 

Twin charging isn't a new concept but combining the TRD S/C with let's say ZPI's 16G, it might be best to have the turbo first since the S/C doesn't see boost until high in the RPM band. Say have the 16G turbo set at 4-5PSI hitting boost at 2K-2.5K then have the S/C with a pully set at 12PSI. You'd probably hit boost pretty fast but then again there wouldn't be near enough room for it all to fit since you'd also need a FMIC.

 

and a FMIC is?

 

Front
Mount
Inter-
Cooler

If you're going to boost anything above 6PSi, you're definitely gonna need this.

 

I don't plan on doing this...the idea just came to me, and I wanted some feedback on what the results would be...

 

I don't know about *definitely* needing a front-mount, side-mount, or any intercooler for *anything* above 6lbs..it's recommended, though. and let's not forget about water/methanol and alcohol injection..

 

Well naturally water and alcohol would work but a FMIC doesn't need to be refilled.

 

Ok.. here is another stupid question. How do you increase boost once you have a turbo installed? Thanks! I need that cleared up some... i'm feeling a bit idiotic now.

 

Modify the wastegate usually by changing the spring or use some type of boost controller.

There's some basic stuff. Adjusting the wastegate will determine how much boost you see.

 

Hmm.. I guess I'd have to see it done to understand Preciate the answer though!

 

Most of the time twin charging a car is pretty dumb. Though there is a kit for the BMW Mini and its super charger first then a larger turbo to help it spool insanely fast.

 

compression on the TC is to high... i would think so atleast.

 

Compression on the tC is actually pretty low for a N/A 4 cylinder engine @ 9.6:1. It would benefit from 8.5:1 if you planned to stay on pump gas.

 

rule of thumb though you do not want to run more than 12lbs of boost anything over 9.5:1 it is just to unreliable

 

soemone that has a lot of money try it out and tell us the outcome. Or someone give me a full sponsorship and ill do it

 

This I know...

Change out the springs in your wastegate...
Your wastegate is designed to relieve excess pressure to the exhaust turbine to limit the amount of boost the turbo creates...
Think of it this way...EXAMPLE
At idle...the exhaust is pushing out 5 cfm of exhaust gas, not enough to make the turbine generate a great deal of boost, none actually...
At 3k RPM, gas is moving a LOT faster, making the charger turbine spool up a great deal...
At 5k RPM, gas is moving a WHOLE lot faster than at 3k, and the turbo can be pushing a great deal of pressure to your intake...
This would be great for more power, but your internals, ie: pistons, rings, block can't handle the stress created by all this pressure...

This is where a wastegate is important...
It limits the amount of exhaust gas that reaches the charger turbine...So it can't spool up to a certain speed, and create more than a certain amount of pressure...

Wastegates have springs inside of them designed to give a certain amount of resistance...
Where you may have a combonation of springs to give 8 PSI resistance, you could change them to give 10 PSI resistance...




Atleast...I think that's how it works...

 

another good rule of thumb: don't get anything done to your car that you don't know completely about. better learn up on turbos and s/c's before you get anything done.

 

why not throw in nitrous into that equation. its like being the 4th wheel into a gangbang. what hole are YOU gonna go in?

 

I was never interested enough into nitrous to consider it...

Just not my thing...
