seen 2 german 2.2 turbo speedsters using this method at the ring last year

cost/faff/weight over gain = pointless imho...

For the hassle of ....... I'd simply get a new intake manifold made up with some less lossy charge cooling device.

that would be more hassle imo!

a permanently working DECENT cooling system, or one you have to keep topping up with fluid etc... I know what one I'd rather opt for. And a proper intake design isnt hard, infact the yanks have a few already (well those who dont go turbo because the S/C cant give enough power

[The Batman]

i havent seen a good effective replacement for the intake manifold yet i have seen a few different methods tried such as instead of laminovers having a radiator built in and also a intercooler setup which also failed however the intercooler setup FAILED terribly terribly bad and lost 30bhp+ 300bhp has been proven reliable with the current setup so i see know reason to try and feck around with it

[slindborg]

current setup being? a hose pipe in the intake? Not saying its the wrong way but the fit and forget route is far more fun. a sodding rad in the intake...... spastics

My devils own kit gave the skyline 25 brake extra shove, and that had an enormous intercooler. I think it would be seriously useful on a turbo, and not remotely worthwhile on a z22. Main use is cooling the charge air.

point missed.... SC

Ahh... if we are talking 80 degree plus charge temps its all good. I could really feel the extra poke.

[The Batman]

Charge temps are more like high 10s or really low20s at 300bhp...

with the current lameynova setup? Well in that case there is fcuk all need to cock about with WIJ

I'm still struggling to get past this:

You need to be aware that methanol errodes aluminium

Though I suppose you could look at it like built-in automatic head porting.

Definitely one for the pig iron boys only if that's true.

Slindborg - yup! That low they never get the slightest bit warm! Not even track abuse! Techie - the us lads been running for years and no failures yet!

[slindborg]

it needs to be in contact with the ali for sodding ages in pure form to corrode, so in a solution that is atomised at injection its going to take centuries to corrode a head enough to notice

[techieboy]

Is there an unused port on the inlet manifold that I could stick a temperature sensor in? Can't remember if there is one that we block up, or whether it's just the MAP/TMAP hole. Would be handy to properly measure it and log it (and temp sensors are cheaper than any of the other sensors I can plug into the Performance Box).

Got a drill?

I dunno. It's all Fast & Furious sh*t and belongs with loud flatulence valves, as far as I'm concerned.

Was hoping for a slightly easier and more factory solution than that.

Change to the z20 ecu and the map sensor tells ya intake temps aswell I believe

That's probably the air temp before the charger. Try after the SC/Laminova and I'm not surprised if that's above 50*C under full SC boost. To get it below 40*C will need some serious cooling mods. Or a better SC.
(drill a small hole next to the map sensor and fit a probe there... Or change to ecu with TMAP )

Oww, and water/meth will make a very high octane fuel, so more power. If you can tune timing for it....

[The Batman]

That's water temp not air temp unless I had a seriously sh** water temp guage

[slindborg]

that means fcuk all....

post compressor air temp is what you want to know.

Oh and as for running higher octane fuel you will NEED to advance the timing to cope otherwise the slower burn that High Octane brings means that the heat will be much later in the burn cycle and can cause the exhaust valves overheat and other such fun. Its basically like running too retarded

What you want is to run on bioethanol and have a sensor to switch calibrations for normal petrol and the bio stuff
