Modification plan for a non-charged H6/3.0R

Bang for buk would ve a sc kit as stated but all comes down to budget

Or a backyard turbo build

An electric water pump frees up power because there is an optimum water flow rate for cooling. The mechanical water pump is designed to achieve this at relatively low revs. As revs increase, the pump tries to pump more water than needed (it is geared to engine revs) thereby consuming excess power. The electric pump consumes a constant amount of power at optimum water flow, or less if it is set up as variable speed. It does need the removal of the mechanical pump impeller and thermostat to achieve maximum gain.

Other ways to free up power are based on temporarily isolating things like alternator and air conditioning compressor at WOT. This can be done for short periods without adversely affecting the electrical system (because there is a battery in the system) or cabin cooling (because you probably won't even notice a small change in temperature during a 0 to 400).

That was my understanding. Up to 10 kw is the figure on the Davies Craig electric water pump kit and is only a maximum. When you look at price to power, may not seem like an obvious mod but if you are trying to squeeze Kw out of a na engine then it might be an option worth looking at.....

Wait until the end of the year and dawesy and I will be proving its possible

That's 8 months away

I'm going to be on deployment for 5/6 of those months

SegR: The E85 option allows for dual fuel on the same tune

I'd consider that if there were a servo nearby which sold it. Out of curiousity, what limitations apply when you include multiple map sets in a tune?

Nothing, as far as limits go. Your 512Kb ROM is space limited but the testing is in progress.

E85 is heading north of the river in a few weeks, last Brisbane visit I had the guys were more excited than a 4yr on Christmas Eve lol

AC is already cut at WOT (>80% i think)

I wasn't aware of that. Clever car isn't it.

[Robbks]

pretty much every car that has AC fitted has some form of load or rpm cut, most ECU controlled vehicles have both.
my 96 Starlet does..!

Oh for the days of manual window winders, V-belts and trying to balance a couple of twin throat Webers (not).

Some headers, catback, stock cats fine for NA

Get yourself a mad tuner and tune the hell out of it

I have given some thought to the intake (CAI) for a long time but not sure if gains can be made there, the factory system allows for a reasonably decent air charge in stock form

So you don't see the point in replacing the cats (a few others have mentioned it's a good idea).

What do you see as being a good pipe diameter for the catback either (a) to keep it NA or (b) to start NA and move to a charger in the future?

With my car making another 27 - 30 kw over stock around 7200rpm mark after the headers being fitted - I doubt the cats are any restriction at all.

Raptor doesn't include cats for the following reasons

1. customer has free choice to use the best/worst/cheapest or most expensive they like
2. Cats can fail, Raptor has no desire to try and work out that issue with a cat manufacturer, nightmare.
3. Adding a cat of brand X,Y or Z may turn people off the header, as cat brand X, Y or Z may be perceived as being of insufficient quality, flow or some other hearsay or fact.
4. Factory cats in good condition seem to deliver the goods for any NA engine, gains from aftermarket would be slight at best and definitely a lot dirtier out the pipe

Imagine if you have a cat fail on a K2 header, how the hell do they warranty that from Japan and whats more then you have to start cutting up your precious one piece header if you want to do a local fix.
