inlet temperatures, boost and nanas..
Turbo Mini Forums

Just wondering if anyone knows what their inlet temperatures are and at what boost? And what power you got at that temp?

Cheers

Matt

I saw on my Mini at 105kpa (instead of 95 ambient) temperature elevation was 4 degrees. Then I moved the IAT.

I'm just running-in at mo (150 mile so far - wahhaaahay) so very little boost, maybe 2-3 psi. AIT shows 36-39 deg C, just prior to plenum but after an RST intercooler. This was on a 20 deg C day.

Minivanless, but reluctantly happy living with the decision. There'll be another one day.

The DON rarely goes over 40 deg.

Before I installed an intercooler I saw >70 degC inlet temps on a 28 degree day (my thermostat maxes out at 70 degrees!) It was with 8psi but not sure on the power..

BTW.. rarely see above 40 degrees now the IC is in..

Without my cooler I was seeing around 60 degrees on VERY low boost (6-7psi) now its about 25 degrees at the same boost. Looks like the IC is doing its job. Im going to take some logs when I get the chance to wind the boost up!

Tom thats good going to keep it below 40 degrees...what boost was that with?

16psi, we've never run any more than that.

Did some more data logging, and im now getting 33 degrees at 10PSI with an ambient temp of 22 degrees.

what where you seeing before you had the intercooler fitted?

Urm.. at 7 psi 60-80 degrees depending on how long I was on boost for (generally not very long either)

Hows the mapping going lately, did you manage to get the idle manifold vacuum down with the mods to the plenum or are they still the same.

All the vacuums seem constant now. Vacuum at idle is about 50kpa.

Mapping is going well untill that damn fuel pressure starts increasing. Ive got the map to a point where all the values up to 5K and 170kpa are only being adjusted by 3/4 on the table but I keep having to turn off auto-tune as soon as the fuel pressure goes up as it knocks the numbers right back then!

If I can get the fuel pressure sorted, a couple of hours of driving would have the map sorted. Robert sent me the logworks program, looks like an awesome program. Hopefully then I can get it fine tuned, and maybe increase the timing a little more too.

I managed to do some more fine tuning over the weekend as the new clutch is allowing me to run more boost.

After reading the thread on inlet temps I data logged my drive and at 15PSI the inlet temps were mostly at 35 degrees and once it hit 38 degrees, with an ambient temp of about 27-28 degrees. It just goes to show how efficient the 2wd cossie cooler is with a good air flow through it!

your temps are about the same as mine matty at 15psi, I find the air temp rises approx 1.5 degree for each extra psi of boost

Should be interesting to know your compressor outlet temp and cooler press drop.

All I know isn that the two pipes to and from the I/C are at completely different temperatures(by feeling them after a fast run) and that I have got away with bursts of full throttle at 16 psi -so far.
Guess my engine is not as efficient as the Don then ?,
All this scientific discussion makes me feel pretty inadequate (not for the first time I might add)
As long as it keeps going and makes me smile I dont really want to know too much about temperatures and things because it would only make me worry about them.
