Intercooler = Power?

Help us all great one!

Now you've just made yourself look silly by claiming to have been well educated and misspelling anything remotely technical.

I don't know if you actually read that site either.

Slowing the charge through the intercooler may not be as bad as you think, to a point. If the air hurries through, it's not going to be cooled at all.

By the way, you're assuming that the air takes the full '5 metres' to accelerate to 4m/s. I'd be interested to see why your other air accelerates faster.

Yes. You can get more power.

Will you get more power? Maybe not.

If it flows better (tank design, end plates, piping) then you'll get more power. As the turbo will not be robbing as much exhaust energy for the same inlet pressure to the engine, therefore making more power. This is one measure of efficiency.

Also, the inlet air maybe denser (although this is not all that significant usually), depends on how hot the air is entering your engine at the moment. ie. efficiency of an engine depends also on the heat difference between input and output air.

More often you will realise more power (that's a relative more power) by increasing the timing and or boost pressure. (But a cooler can make more power before changing any engine parameters).

If your running stock boost before the new cooler goes on you may gain a little bit of power keeping the boost the same. I was running 10psi with the stock cooler, then I put on a hybrid cooler on, was still running 10psi and the HP difference was huge.

So it depends on how efficient you cooler was at the set boost level to what difference you will see.

hey, enjoyed this topic, im about to pick up a intercooler for a r33, which size is the most comon for this car?.600 x 300 x 70mm ?, has any one seen the same perfermance with size: 450 x 300 x 76mm ?. just wondering whats the best to get if someone could give me a hand. ;) .aslo, Bar and plate core? or tube and fin?, any difference when buying one? except for price?

      Input shaft bearing. They all do it. There is always rollover noise in Nissan boxes - particularly the big box. Don't worry about it unless it gets really growly.

      For once a good news  It needed to be adjusted by that one nut and it is ok  At least something was easy But thank you very much for help. But a small issue is now(gearbox) that when the car is stationary you can hear "clinking" from gearbox so some of the bearing is 100% not that happy... It goes away once you push clutch so it is 100% gearbox. Just if you know...what that bearing could be? It sounding like "spun bearing" but it is louder.

      Mistakes were made, my R34 Story

      Yeah, that's fine**. But the numbers you came up with are just wrong. Try it for yourself. Put in any voltage from the possible range and see what result you get. You get nonsense. ** When I say "fine", I mean, it's still shit. The very simple linear formula (slope & intercept) is shit for a sensor with a non-linear response. This is the curve, from your data above. Look at the CURVE! It's only really linear between about 30 and 90 °C. And if you used only that range to define a curve, it would be great. But you would go more and more wrong as you went to higher temps. And that is why the slope & intercept found when you use 50 and 150 as the end points is so bad halfway between those points. The real curve is a long way below the linear curve which just zips straight between the end points, like this one. You could probably use the same slope and a lower intercept, to move that straight line down, and spread the error out. But you would 5-10°C off in a lot of places. You'd need to say what temperature range you really wanted to be most right - say, 100 to 130, and plop the line closest to teh real curve in that region, which would make it quite wrong down at the lower temperatures. Let me just say that HPTuners are not being realistic in only allowing for a simple linear curve.

      I feel I should re-iterate. The above picture is the only option available in the software and the blurb from HP Tuners I quoted earlier is the only way to add data to it and that's the description they offer as to how to figure it out. The only fields available is the blank box after (Input/ ) and the box right before = Output. Those are the only numbers that can be entered.

      No, your formula is arse backwards. Mine is totally different to yours, and is the one I said was bang on at 50 and 150. I'll put your data into Excel (actually it already is, chart it and fit a linear fit to it, aiming to make it evenly wrong across the whole span. But not now. Other things to do first.
