Some turbo what ifs...........

[jonseyq45]

While pondering my navel, I thought of a few things.

The rear turbo mount uses a long connector pipe to the intake, What if we used that length as a intercooler? Build a pipe with an integral water jacket. This in turn will connect this to a small secondary cooler\radiator. An electric pump will used to circulate the coolant.

Build a water/methanol injection system using brass jets from a Mukuni motorcycle carb to allow fine tuning.

Use an adjustable restriction in the fuel tank return line to increase fuel pressure in the fuel rail.

Create a new kickdown switch at the gas pedal to allow kick down to happen sooner and be adjustable to when it happens. Other vehicles allow this.

Just wondering ???

Working on more.Jonsey.......

Think this needs to be in the VH/VK Forum.

In general, non-oxidating liquid injection is not good as it displaces fuel and air. Why DI is optimal, as it's air displacement is minimilized.

The problem with cooling a ~2.5" tube just on the outside is that most of the air will never come in contact with the outer surface. Intercoolers work by separating the air through many smaller tubes where more of the air will contact the sidewalls.

The "adjustable restriction" in the fuel return is a common fuel pressure regulator that is preset to the desired pressure level and then automatically adjust via vacuum/boost pressure in the intake manifold.

You're thinking along the right lines however you really need to use an intercooler since only the air molecules near the outside of the pipe will be cooled in the setup you've described.

What you need to use is an inline air/water intercooler like this:

Sounds a little excessive IMO... Id either go non intercooled or do it the usual way.. When you're running stuff under the car you have to think about ground clearance, however depending on the size you might able to put it where the cats are.

Use the AC system to chill a separate evaporator................that should provide 14 seconds of cooler air..............requires you to think about it in advance [use high presssure solenoid valves to switch ac lines between two evaps]. OR Use chiller to cool a larger volume of water and circulate.

150F air chilled by 40F water or the mass of evap depending on which provides the least psi loss.

Remember losing 1.0 psi of pressure is 6.8% whereas 110F temp drop gains 10% so you want an intercooler that only drops pressure by 0.5 psi max losing 3.4 and gaining 10 neting 6.6% more density [power].

Whether it is worth it to gain 25-26 HP [400 x 6.6%] ?
