HP, how much can a LIL 2.5L take? How do they Blow?

Thanks Gary for the encouraging words. Glad yours is holding up well. I’m actually holding it up as a benchmark.

I kinda studied the crap out of cooling (IC; air to air, air to water, etc) and the water/alcohol seems to make the most sense for an SC in this car. In the past I've pooh pooh’d it as a kludgey solution but the more I’ve read…it’s legit, not really tricky and not really a big hassle.

The concept and implementation was actually developed for super charged fighters and bombers in WWII. Got them up in the air... fast.

Aside from heat, the super charger itself has limitations. It needs to be the pretty small form factor it is to fit the car physically. How much more it can be milked at the low end without actually being a drain at the top end or, spining the sc to fast, isn’t clear yet, pretty much a matter of doing some math though.

So, if your getting 270hp comfortably, thats what I'll aim for. According to the manufacturer, I’m already there and then some, but I’m not buying…yet.

Regards, PK

BTW, how many miles have you chalked up on your turbo?

Thanks I'll be that benchmark...In the new year I have a few tweeks for the turbo and do some exhaust work.

After each mod I will be back on the dyno to see what sort of results I get.

Everyone here will be updated along the way.


Jaay looked into the air/meth for his supercharged 2.5. Perhaps he can chime in with his research.

pk, from your research do you feel as if the ecu would need a different map than the standard sc map?

Hey Gary
Please do keep us apprised of results from your mods!

ECU remap; actually maybe, but the kit consolidator said “DON’T”. There such… dicks I never asked why. I rely completely on an AIC and at this point I don’t have any complaints (But I also don’t know how well I’m optimized either). With an AIC, for simplicity, I’d steer clear of messing with the ECU. I’d think trying to juggle the 2 while tunning would be a pain.


I’m not altogether sure how much remapping can be done to the ECU. I know they can be flashed from “a” to “b” and “chipped”. But what can be tweaked in-between, I really don’t know. If I could do it, (have an interface and software) and ditch the AIC, It sure seems like it would be a lot cleaner.

I do intend on getting a more advanced AIC. Unfortunately, the ones I like don’t have any baseline maps for this car, means starting from scratch. I’m not crazy about pinging the _ell out of the motor just to get to something close. I suppose I could hack into mine and use some sort of data logging software/hardware to extrapolate a map…dunno.

Anyway, good luck with the mods, look forward to the results.

PK

P.S. Do you have an AIC and if so, who makes it?

Forgot to answer this in a previous post:
I have done around 11,000 miles in the last 6 months on the turbo.
