DIY Supercharger/CAI mods

[Weirdo_Joe]

Yo, I know what ya mean! Keep in mind, I didn't know anything about cars 13 months ago when I bought the Aveo... Except that it was pretty. At this point, I DO plan on getting another car at some point. I consider every payment on the Aveo an investment in a new car; but at the same time, I gotta have some fun with it while I got it! I can over-pay monthly and still do mods... I test drove a base model Lancer yesterday, and was WAY under-impressed. I just saw on Fifth Gear that a Porsche Caymen Manual does 0-60 in 5.8 seconds... That puts me only 4 seconds behind a supercar. I look forward to seeing what I can do with the Aveo, but I know... I'll probably trade it in in a few years. They were ready to let me drive off in that Lancer... I guess I just didn't want it, yet. I love my Aveo, & I know you loved yours, too...

Porsche caymen is not a super car, and 4 seconds in a 0-60 is like 1/2? a mile behind them..

[Weirdo_Joe]

Okay... then my Aveo is less than 4 seconds behind a Porsche Caymen, which is not a supercar, but an expensive and nice car, nonetheless. It's a matter of perspective; I've nearly taken 4 seconds off my 0-60 mph time in one year... So, getting another 3 seconds up seems pretty easily attainable. At that point, i'll be less than a second behind a Caymen's 0-60 in my cheap lil' Aveo. (Note: I'll bet the Caymen would be over 6 seconds at this altitude... ; )

Back to the actual performance gains... as I mentioned, I tweaked the position and ducting on the supercharger a bit, and I wasn't the only one who thought that there was some improvement.... today's test proved that there was a slight difference; 9.63 seconds. That's 1.34 seconds ahead of the previous time with no fan. That's 1 1/3 second faster 0-60; with a .22 difference made simply by adjusting the placement. I'm quite happy with that!

the first second off the time is easiest, every second after that is 2-3x harder than the one before it.. so second 7 is like 2000x harder than the first..

U should put a fan in the exhaust to clear the combustion gases out faster so the intake fan can push the air in there faster.

[Weirdo_Joe]

Hahahaha... You're joking, right? I may still be a newbie, but I've never heard of such a thing... I AM planning on doing a CAT-back exhaust this spring... that seems to be the way to go for clearing the combustion gasses out faster... I hear headers are great for top-end power, but 1. Last I checked the guy wasn't making any more and 2. they kill your initial torque (so I hear). With the CAT-back, as me and my neighbor were checking out... originally you got 4 pipes going into the CAT, and ONE 1 3/4 inch pipe leaving... it makes sense to open that up, and I hope it will provide a benefit without the sacrifice in torque.

As for the supercharger, I am SO pleased with the results, I just ordered several 80 amp relays to implement the 36Volt operation... the 1.34 second increase in 0-60 time was from only 24 volts... ;D I have left the supercharger in place since the last tests... but I did move it around about half a dozen times. This thing is stuffed in the wheelwell, though... providing a NICE boost. I can flip the switch to turn it on while I've got the gas floored, and after a 1/2 to 3/4 second delay, there is a NOTICEABLE burst of speed... noticeable in not only the times, but in the car from the sudden acceleration, and on the speedometer/rpm gauge as it starts climbing faster... I am VERY excited to see what the next 12 volts do...

And I know what you're saying, rabbit... in theory AND practice, this last project was the biggest/hardest yet. It also provided the SINGLE largest performance gain yet. And for some reason, even having to learn the electical and stuff; it SEEMED easier than the CAI install. In fact, everything about working on the car is getting easier, so I think the "learning curve" makes a difference in how "hard" every next second seems.

I just tried posting some more pics, with the finished product, but there seems to be an issue with the image uploader, again... Doing it the same way I always do; I'll try again soon! Have a fantastic week, everyone! Oh, and has anybody considered the do it yourself tuning software that's available? The ones you hook up with a laptop to your OBD=II port? Just wondering... I emailed Trifecta, asking if they had Aveo tuning software ready to ship. I read here that they were working on it awhile ago. Seeing as how I haven't heard back from'em, I'm considering the DIY route for that, too.

I want to see a track time......

[Weirdo_Joe]

YEAH!!! Me, too! I'll be hittin' Bandimere Speedway for "take it to the track day" at least once this summer; probably after adding the 2 1/4 CAT back exhaust or sports rims & tires... Not sure which I'll be getting 1st; depends on when the snow stops. I'll post the time tickets; probably won't be outrageous, partially due to the elevation. You guessed your 0-60 mph times at less than 10 seconds with fewer modifications... But that's in Florida, near sea level. I'll bet my time now (9.63) would be under 8 seconds if I were close to sea level... Nonetheless, I am excited to see my 1/4 mile times! I'd be REALLY happy to be in the low 16's after a few more volts & either rims or exhaust. I'd be surprised if it was any lower, actually... But who knows! I'll post the 0-60 mph time after adding the other motorbike battery, and try the picture uploader again in the near future; before the relays arrive. They're gonna be 2-3 weeks coming from Hong Kong, but most relays here that are 24-Volt only go up to 40 Amps... I need at least 50, with 60 being "preferable" according to the GA Projects instructions...

[aveosam]

I was absolutely joking... I think your mistaking placebo for real results. Do u have specs on this fan? Does it spin fast enough to create a pressure difference? If it does (which I highly doubt), any gain will be completely negated by additional weight.

[Weirdo_Joe]

Placebo effect can't even begin to explain a 1.3+ second difference in time... I finally dug up the link; any disbelievers, read this: Most notably, the design challenges, which I think is where it states how in theory, it's nearly impossible to create boost with an electric fan... nearly. And the e-supercharger scams.

And if anybody wants to come to Colorado, I'll make you a believer... ANY TIME.
