I'm about to rebuild my supercharged engine.
I've decided the water injection wasn't offering the temp control I needed at 22.5psi.
I have 3 options:
1. Fit a W2A intercooler into the manifold.
2. Fit an external W2A intercooler.
3. Fit an FMIC.
Pros:
1. They're available and a little machining and it fits.
2. I can get better cooling and improve the air entry into the manifold.
3. It's easy reliable and I have an intercooler hanging around.
Cons:
1. Has he complication and weight of a pump, water plumbing, pump and an additional radiator.
2. See above and add building the box and supporting the intercooler somewher in a very cramped engine bay.
3. I still need the box but room is available and a little plumbing isn't too hard.
I lean toward option 3.
My reasoning is I can fit the intercooler in front of the radiator and plumb it up fairly easily. Core size is 600mm x 300mm with a 2 3/4" inlet and 2 1/2" outlet. All the claculations say it will support up to 700 HP.
I happen to have the intercooler (so I can save the cost of a new one) which came off a Shelby Elenor (Gone in 60 Seconds) Mustang that was making well over 600HP at the wheels.
To get the air out I can build an aluminium box to go under the supercharger that is splt diagonally (top rear to bottom front) so I can take the air out from the supercharger, through the intercooler, and back to the rear of the "box" which would discharge it into the manifold.
The existing setup has poor air distribution (which may have contributed to the blown h/g) and retunring the air to the centre of the rear of the manifold would give it far better distribution.
If I ran air to air I would use the existing water injection to spray the intercooler core with straight water. This would leave me a lot of unused methanol to get rid of but I'm sure I can find a use for it.
I'm after any and all comments on my options.
I plan on this being the last 1UZ build I do for a few years so I want to get it right.
What do you think?
