2015 Mazda 6 Sport
I'm asking out of curiosity because on Instagram some fellow mazda owner said he would be supercharging his car and honestly I never gave it much thought, but now i'm very curious.
Uh, not in my book. I have never felt such a weak-kneed 2.5 engine in my life, ever. This is really giving me grief... because my 2017 Mazda6 6MT feels like a really, really cammy engine... Not what I want in a pretty large four-door sedan. I feel cheated, by way of bottom-end engine power.... which will work well with the strong low end this engine offers....
It's a way to do it cheaper, obviously it would be better to have it part of the exhaust manifold. The stock muffler is so huge that space is adequate to put a small turbo (target maybe 5-7psi)... In the end I've let go of adding FI to this engine and focusing on squeezing the extra bits of power out of this engine that I can (intake, exhaust, tune, and eventually water/meth injection), and I recently filled the rear motor mount with polyurethane construction adhesive which really helped make the car feel faster (less latency do to engine rotation).Rear mounted? As in, under the car? WTF would you do that when Mazda makes a turbo motor that you could use pasts from and do it right.
You may be right, one friend was arguing that he could help me do it cheap FWIW, and yes 7-9psi seems doable... Either way I've let go of forced induction, honestly my car feels fast now (probably 15% more power than stock) so I've shifted my limited car modding budget to focus on suspension & braking (well and water/meth injection).No, its NOT a way to do it cheaper... adding the oiling, the IC piping all the way back there... who did your parts math? You can get a stock usedCX-9 turbo for under $500 with manifold. The stock SkyActive 2.5 is good for 7-9psi.
I don't think the compression ratio would be much of an issue. My primary concern is the quality of the ECU tune, as this is what can easily make or break a good build and blow your motor. Now, if you're pushing higher boost, the lightweight skyactiv connecting rods and pistons aren't really up to the task but you wouldnt need to really rebuild anything else, maybe just port the heads or something.Obviously it's possible to supercharge this engine for the right price, figure at least 5k, but you would be very limited in amount of boost to add without at least a partial engine rebuild because of the compression ration. Plus this is all assuming you can find someone to custom fabricate the the parts needed, because adding a custom turbo is actually less work than a super IMO (I've thought seriously about adding a rear mounted little turbo...).
I think with some other changes you can get enough out of this engine to be friction limited more of the time than power limited
I think that my 6 is much faster in reality than it seems on paper in Peak HP (should be avg HP, or some distribution of HP over rpm range...)
Dude, do you know ANYTHING about cars? If you blow rods or pistons, you HAVE to rebuild the whole thing cause you have NO idea what else might have happened.the lightweight skyactiv connecting rods and pistons aren't really up to the task but you wouldnt need to really rebuild anything else, maybe just port the heads or something.
Dude, I don't think you understood what I said.Dude, do you know ANYTHING about cars? If you blow rods or pistons, you HAVE to rebuild the whole thing cause you have NO idea what else might have happened.
100%This much is certain -- the SkyActiv engine, being a high-compression design, is going to be very, very hard to get material boost into without severe detonation problems unless you intend to run specialty fuel all the time, which makes it completely impractical for a road vehicle.
