Already smoking? I'm surprised it took so long.

don't forget the oil cooler you'll want, as well as the new fun cooling issues you're going to run into in hot weather which will necessitate lots of fun ducting and venting (does that fall under aero?). then the stress that extra power puts on a drivetrain (clutch, mounts?), and slowing down from higher speeds means more brake heat, more stress on wheel bearings.
i think that's why its "only" that amount, because they understand you're going to have to fortify everything else on the car to handle more power so the reality is a lot more points involved.
Low boost = almost none of those issues or issues that won't be very much of an issue for cooling according to other folks who have boosted their car. This car keeps very cool when I monitored it at the VIR heat wave event. I have an upgraded RMM, yes I'll have to upgrade the rest eventually. Clutch is proven to be fine for awhile and once it goes after 30k or so I'll replace it with another OEM one. Axles and transmission are fine I'm not launching the car. I have 1.2" bigger brakes all around already so not an issue being 5-10 mph faster in the straights.
I wouldn't be the first boosted mazda3.... These cars can take some abuse and being only 50 more whp than I'm at right now isn't that much... This of course just possible idea like many others that have been produced in this thread. I don't mind replacing things with new OEM parts over time. The parts are pretty cheap lol.

Nah, i got the hot-fixes applied, no smoking. I'm gonna keep it on a bandaid treatment until it goes for good.

all cases, all years, 5 or 6 speed... part number 17100... anywhere from $198 to $498 lol. thats no fun at all.
Yeah it's pretty dumb. A lot of stuff is similar, but different.
Also, is it really only +14 to boost a car? +5 forced induction vehicle, +2 upgraded fuel injectors, +7 aftermarket intercooler,
No, wrong
"All of these cars MUST be assessed by the National TT Director for re-classification into a new TT Base Class!
Motor Swap, Aftermarket Forced Induction, Modified Turbo/Supercharger, Aftermarket Head(s), Increased Number of Camshafts, Hybrid
Engine, Ported Rotary motors, others (see TT Rules sections 8.3.C, 8.4, and 9)
(e-mail the below information to the National TT Director at <!-- e --><a href="mailto:greg@nasa-tt.com">greg@nasa-tt.com</a><!-- e --> to receive your new TT Base Class)"
Yours fall under Aftermarket Forced Induction which means that you would have to get a new "base reclass" depending on your power to weight, and the type of car. Those minimums you think you can do? (ie 14.25), most likely will NOT get a reclass of 14.25, instead will be more between 14.25-17 or whatever the next lowest class is. That is because it depends on the vehicle. Where a stick axle mustang will be "base classed at 14.25 power to weight since its handling would be worse, a Mazda 3 would end up with a "lets say" 15 power to weight because it handles better.

Oh wow, great information DJ. Thank you! I was going to say something seemed too good to be true

just making sure all your ducks are in a row...from my experience, non-factory-boosted cars on track are usually the first casualties (and often weird stuff that is a bitch to predict...burned exhaust valves, manifold studs backing out, boost leaks), its just such a torture test out there that any weak link will show itself and the stuff you piece together has to be done carefully which i know you understand.
these guys with boosted N/A cars...do they track them? and not like hyperdrive track....like, entire seasons of DE, time trials, hillclimbs where they see sustained max load/high rpm stuff? if not, take their reports with a grain of salt as street driving and making passes at the strip is nowhere near the same level of stress. if they have...make them your new best friends, and pick their brains for every thing they're worth :lol:
Re: Project 2.Slow Mazda3 - rherold9 - 09-22-2015
Yeah, I don't believe they do entire seasons. That's something I'd have to prepare for. And yeah the little things add up. Low boost should help minimize some pain over time. I probably won't do that a turbo build. Still be interesting to be one of the first boosted 3's(2nd gen) to be running years at the track. A first gen that did this had a year of no issues until suddenly the car burst into flames on track due to the fact they owner ignored rising temps on track from a bad turbo seal and oil caught fire.

Re: Project 2.Slow Mazda3 - Goodspeed - 09-22-2015
If you feel you must boost, look into a Rotrex supercharger. Extremely simple, self contained oiling, and they're the coolest running form of FI all else being equal. They're the weapon of choice for FI track Miata guys since turbo'd ones just explode unless you spend $$$$$, plus the linear powerband. When I had my NB I never heard of one failing or anyone having issues on track, and they've done 24 hr enduros with these.
This is the entirety of a Miata kit for example

Very difficult to find a kit these days. ask me how I know.
Re: Project 2.Slow Mazda3 - rherold9 - 09-22-2015
Used to have a supercharger kit available for our cars by a company, but now we don't. My tuner was offering kits for a short while, but I don't think he is now. FI would be nice though. Car feels so slow. Barely getting to 110 at VIR. But that's because of driver corner exit speed is low on back straight and only street tires
Tbh, my cars curb weight depending on model is 2820-2990 or something along those lines + me = 3000-3100 - 36 pounds for half a tank of full(from curb weight)= some random number around low 3000.
So, even if in the future I do let's say want like 200hp I and need to be like 15:1 I can still strip 100 pounds which is nice because I wouldn't have to go crazy to strip weight hahaha.

I have a feeling once you go HPDE3 you may reconsider your weapon of choice...

How much more bench racing will happen on this thread? Tune in next time where Ryan will discuss the possibility of LS swapping his car, converting it to RWD, and putting the engine in the middle of the car. Will Ryan have the balls to make his car look like a Bugatti Veyron? Who knows until the next episode of Mazda3 Bench Racing!

If I can sell a spray-painted E30 and a rotted-out E36, you can sell a Mazda3.

Even if the car has no cats, ABS light on, and TPMS light on?
I guess people will buy anything for the right price :dunno:
