The data with the new intercooler will follow

I am very curious

Hi ANMVQ

You did start us on the frozen boost heat exchanger, I'm also going for the braided hoses , thanks

Just google search "US Dyno higher than Australian" and you'll find hundreds of comments about US vs AUS dynos. Read into them what you will.

Our fuel is slightly different to yours but we basically we have similar grades just with a different grading system. Where you have 93AKI we have 98RON. I would assume that he is probably running 98. We also have 100RON which is slightly better but basically just 98RON with a splash of ethanol. Then obviously E85 and crappy 95 and 91 RON.

Bingo!

Getting the frozen boost heat exchanger and heat shielded water hoses to and from the Intercooler fitted over the next couple of days. Also putting a temp gauge in the heat exchanger to monitor the outlet temps. Should probably put a temp gauge after the Intercooler to get a real picture of efficiency.

It will be put on the dyno , hopefully my tuner should be able to advance the timing a bit with cooler intake. I'll ask him to give a base map before he plays around with the tune.
He is still having a few issues with the 850 injectors waiting for info from uprev. Does anyone know if you can set the ECU to recognise 850 injectors, calculations are incorrect for K's I can travel with fuel in tank.
I will post results in the next few days.

HP = Kw * 1.34, and yes, Dyno readings down-under tend to be lower than the numbers in the US - its is because we are upside down and see massive friction losses on the rollers (LOL)

Damn man wish you were in Brissy!

how's it feel compared to stock? any plans to go E85?

vlad370z

awesome gives you a bigger smile
E85 not presently

Frozen boost heat exchanger installed + Southbend Stage 3 Daily with 19lb steel flywheel

base line with heat exchanger installed then after tune. My tuner could repeat same numbers during all 15 dyno runs without cool down .

Do you have the dyno data pre-Frozen Boost install? Did you see any KW/N-m (metric system lol) gains?

ANMVQ

I don't think he has temp number pre heat exchanger but the key is when he says"My tuner could repeat same numbers during all 15 dyno runs without cool down " The Stillen one you'll get two runs the MAX before it gets heat soaked. I remember when I went to the track pre heat exchanger ( Was only 8 cars there with me) after my first two runs the car ran SLOW, I was so heat soaked I could actually feel the car lose power on the runs after, I would have to let it sit with the hood open for a good 10-15 mins after each run to cool off. The stock exchanger and location is not smart :/

Might be too late for you to see this question...

Where and how are you measuring IATs?

I have heard that Uprev was now able to splice a Temp Sensor into the MAF harness, then tap and install the sensor wherever you want it (Intake Manifold after the intercooler would be ideal for the Stillen S/C, so you would no longer be logging IATs in the front bumper). I would like to see if anyone has done this.

That is interesting, I have mine reading via OBD2 port (same as uprev) and have seen them get close to ambient but also figured they were 5-10 degrees higher based on reading location.

Honestly I can't answer that, the tuner had all kinds of things hooked to the car and said he could see them dropping when it started spraying but I didn't ask how. He's out of town until sunday but I will email him and ask, maybe he was wrong and using the MAFs but he shouldn't see the temp drop there. By mistake I did one session at Sebring last weekend on my no meth tune and the aquamist off and the car felt down on power by the end of the run, that didn't happen on any other runs so I'm assuming it had something to do with the aquamist but I'm not sure what.

Pro4Jackster

That would be fine for a GTM supercharger because your MAFs are in the factory location. Which is after the supercharger and intercooler. So you wouldn't benefit any from moving the IAT sensor, they are already reading the temperature that the motor is actually seeing.

Stillen's setup on the other hand, unless I'm mistaken, reads temperature from before the supercharger, intercooler, and meth nozzles. So the car actually has no idea what IATs are by the time the air gets to the motor. Moving the sensor into the IM would be a big step forward for the Stillen supercharger.
