Like that Photo :excited: gave me a few ideas.
Looks like you used to have woofers and now you have drywall... :-)

I will be installing the AquaMist water/meth injection.
I have the 9.5 CR Carillo pistons and rods - race bearings and ARP bolts.

Will be posting all of the particulars once the build is satisfactory completed.

clkio was still running standard stillen heat exchanger when motor popped.

They are talking about moving the MAF's which are currently before the supercharger to a better location as the temp probably changes between where it's measured and where the air ends up entering the engine. Not sure where the best location would be though.

Anyone ran a water/meth kit also?

A question for you'se guys in the know ...
Trying to figure this all out in my head (a very dangerous place to be I might add)

The Stillen charge tube splits at the throttle bodies ... and the difference in length between the 2 isn't all that much...shouldn't have that much affect ?

And I'm not exactly sure where the IAT is measured ... at the Stillen manifold ?

Anybody know for sure ???
Stillen are you there ??? Help ??? :tiphat:

IAT is measured at the MAF, so any change in charge temp after that won't be compensated for by the ECU.

Thanks Chuck ...
I thought so - but thinking about this too much introduced some doubts in my mind -
So ... moving the MAF's to the charge tube after the SC'r (if possible) still wouldn't fix it all since the air still hasn't passed thru the Intercooler ?

Is this correct ? aaarrrggghhh - another dilemna

I think I may have cross coupled the AquaMist instructions in here as well.

Chuck33079 12-29-2014 12:20 PM

Correct, the maf should be after the compressor and intercooler if we want the ecu to have an accurate reading.

ANMVQ 12-29-2014 12:49 PM

Just spilt the tubes after the SC, Dump the Stillen intake and go with a M370 or Z1 :stirthepot:

That, with an air-to-air intercooler and you'd have one hell of a setup.

8.5:1?! holy hell man that's low. have you tuned the kit with the new engine build yet or still in the making? are you looking to go much higher psi than just the upgraded impeller?

:iagree:

I took the day off with my engineers here in Switzerland,
the topic with the MAF's to study it.

The air mass is not a problem.
The two pipes before the compressor is in the size and length OK.
Important here is the installation of the supplied by STILLEN apron,
or the air to lead not directly to the air filter.
Turbulent air flow.

We think, the only problem is the temperature measurement.
As soon as my "Z" from the engine conversion comes back, we will be at the Intake- Plenum install a temperature sensor capable of measuring the effective inlet temperature. So I can compare the two measurements and, if necessary, correct the MAF- temperature.
At the moment we do not yet know how?

Installation and Location:

MAF via OBDII evaluation:

I will continue to report in the spring.

See you soon and happy holidays from Switzerland :tiphat:

Love the draw up man :), But you should really try to get a read pre and post SC, MAF readings,

Looks promising . :iagree: .Thanks for the post !!!

Plan 'B'
 
Been doing some leg work ... here now is Plan B :

Having to stay with the 'Stillen' as is ... most everything is back in place and it is too late (and expensive cough cough) to change horses in mid stream at this point.

I will be installing a PLX DM-5 AIT Gauge/Module/Thermocouple at the Stillen manifold as Swiss370's illustration shows.

I ran this by the builder and now waiting to hear back from the Tuner.
But so far it seems a much better way to monitor the motor and more accurately do the tune (with better numbers temp wise to work with)

Next question up is possibly an upgraded Water Pump for the IC than the Stillen kit provides...
Thinking here is to create more circulation to accommodate the much larger Frozen Boost Air to Water heat exchanger = lower temps.

Has anybody tried this ??? and where could I find one ...

Chuck33079 01-01-2015 02:21 PM

How is the thermocouple going to help beyond data logging? The ecu still won't see accurate IATs.

Agreed ... not 100% accurate, however, with the Frozen Booost and temps down at the IC, the Tuner may be able to provide the ecu with adjusted and closer to accurate numbers.
Not the perfect solution ... but ... waiting to hear from the tuner.

At any rate ... it won't hurt to know the exact IAT - the PLX gauge and module are top notch.

BTW, I did check out the M370 manifold and Air to Air heat exchanger - a nice set up - but the manifold would necessitate reconfiguring/custom designing the SC'r charge tubes, relocating the TB's, and I would have to eliminate the custom bracket brace.
Another deterrent was finding suitable room for proper placement of the larger Air to Air heat exchanger.

Will keep you in the loop :tiphat:

You see mikey, I bought a used supercharger kit from g37 forums and the kit had all the upgrades done to to it (pushing 12.5 psi) on the stock engine, car was making around 480whp and 357 torque, I went ahead and installed the meth kit but didnt tune yet. After few days of driving with the supercharger, engine blew (before I got to tune for meth) so I found a great deal on the rebuild engine I have right now. Unfortunatly, car made less power 462whp but made 380 torque but still not tuned for meth. I will be running meth around March and see how it goes. If I am not happy with the setup at the end, I will be removing the supercharger, selling it and buy a TT as the built engine i have now is better for a turbo setup.
