Premium makes more power for to Mazda 3? Common sense typically says no unless a tune had been done. I do thrash mine regularly because mountains and curves.

It has a 10:1 compression ratio iirc. Its border line, but I feel its high enough for at least mid grade. I need to hook up my scan tool and monitor some things, but it feels like its advancing a bit more than on regular. Has a bit more pull. No signs of the typical hesitation with using improper gas. It feels a lot more responsive.

Grandad is thinking about buying this. 1969 DeVille hard top two door. It had the added option of the padded vinyl roof thats split all to hell. Been in storage for 17 years. 

 

/should/ be the 7.7 L v8 and turbo 400 tranny. Drift car? Hope so. 

 

jeez more like drift boat. with a 7.7 motor. i wonder how much power you can make when you stick a blower on it.

in pretty much every car that calls for regular fuel that i've ever driven, it's always seemed to be a bit better with higher octane fuels. 

 

some more than others. most not enough for it to be worth it especially when it runs just fine for daily use on regular

 

they always say it makes no difference but in my experience it does (especially on responsiveness which you seem to notice too). I just normally keep quiet about it because ill get shut down by all the people who scream "NO" lol

 

but like I said I'm not used to it being much, and most people would definitely not notice.

I wouldn't of tried it if the compression ratio was in the 9s and a non VVT engine. You'd lose power + gas mileage.

Tbh, the car feels a bit more snappy in cold weather, particularly in the higher rpm while on a warmer day, it feels more dead up above 6k. Cold air probably is less susceptible to knock. I would wager that on a dyno (not sure of anyone obsessive enough to dyno these things, aside from maybe myself) the difference would probably fall within margin of error.

Oh yeah, the temperature is a big factor. In warmer weather my throttle response is terrible and inconsistent. 

 

Higher octane = harder to burn. Higher octane allows the VVT to advance the timing more without knocking.

Try getting those rpms up there in the cold. Even up a hill from a stop (damn the moron engineer for putting a stop sigh at the bottom of a hill BTW), the engine doesn't quite feel like its done at a mere 6500 rpm. I do feel like this engine could benefit from more rpm.

Maybe if you are going for 0-60 times. With its gearing, torque is more beneficial.

I don't know the whole story yet. I've been doing fuck all today so I haven't been paying attention to the news. Just something about protests and nobody willing to hear other peoples opinions, and somehow nazis are a thing apparently? Oh well. I'm going to wait to form an opinion until Philly D talks about it on Monday. He's pretty good about being objective.

Getting 2nd gear to the rev limit gets you to 62 mph pretty quickly, though damn that gearing jump(read: chasm) between 1st and second. Were this a 6 speed, an extra gear between 1st and 2nd would be a major blessing. I feel the 0-60 times were a focus with the gearing choices, especially as 2nd tops out at about 62 for those metric heads. I'm used to it by now, but revving to 4K in 1st going up a hill just to not annoy traffic behind me on the 1st to 2nd shift is a bit excessive.

Thats why I don't like the car. 

 

Also, does yours "pull down" your RPMs once you hit rev limiter rather than just cutting off fuel like most other cars do? Its a weird feeling.

I don't commonly aim toward the rev limiter, though that is what it felt like. Considering the effect of engine breaking (electronic throttle probably closes at the limiter), this comes as no surprise. I would assume anything with an electronic throttle will probably behave this way.

 

Even my rushed pulled tend to see me shift at 6k, mostly out of mechanical sympathy, though when absolutely necessary (merging into fast traffic with semi trucks), I shift to 3rd at 7k (or just right below) without hitting the limiter. 

 

I wonder if a lighter flywheel would help with 1st to 2nd shift. Running the AC, the gearing gap is significantly easier to shift into.

One or two. Depending on what sort of shape its in if he buys it will really determine what gets done with it. I did some gargling and found this guy that makes heads and and intake mani for them that can get you 700 without forced induction.

 

Still though 375 hp 525 torque as is. New anyway.

holy SHIT i didn't think such a big engine would need few mods to achieve such power, and i thought it would be too lazy for its own good tbh,being a large engine and such.

so probably a bad idea to put premium in my protege to see if it can be more responsive?

Yeah its what feels like what is happening. 

 

I usually shift to second at like 5-6k, then short shift 3rd and 4th, then shift to 5th when I'm at speed.

Well you need pistons and a nice cam too. But think about it, you have a lot of cubes from the displacement, you have a four barrel carb from fuel, you have loads of air from the intake manifold and heads, and a cam that lets you spin it a bit faster because you can get the mouth and butt working together.

 

Why would you need forced induction to get big power out of a *shudders* 7.7 liter V8?

because it's more fun that way? i like boost so boost = fun. but big power without boost is fun too.

It wont kill it, but gas mileage and throttle response will most likely suffer. You can try it, just beware of placebo effect.

Yeah, I think I'm going for a lighter flywheel (and maybe a short throw) when it comes time for a new clutch, specifically to improve that 1st to 2nd shift.

 

When driving in Cheapskate mode, I shift in the low 2ks when cruising. The winding uphills spell trouble if a slowpoke forces me to 2nd, though otherwise, this car handles itself well enough around sharp bends that I can hold 3rd nearly all the way up. Can be a challenge in the rain though, an LSD might be helpful. Need some precision to avoid spinning the tire more than necessary.

The flywheel is pretty damn heavy. I didn't care enough when I did the clutch. I only was going to change it if it had a dual mass. I'm probably dumping the car early next year anyway.

I like flywheel I have in my Miata now. Heaviest of the lighter options. Def revs up and down a lot quicker, but has enough momentum still so shifting isn't too hard. It's also not hard to get moving from a stop. 

 

Personally I don't see a point to going any lighter than what I have now. Seems like diminishing returns to me. And makes it much harder to drive.

 

And stock clutch definitely keeps things easy too. I love it.

I didn't think anyone but Volkswagen used dual mass flywheels. 

 

I do really enjoy the handling characteristics though. It's probably not even close to Miata levels of cornering, though I do not feel excessively limited in driving through the mountains and can take a lot of turns and curves with barely (if any) use of the brakes, even going above 50 mph. If I want to drive calmly, the car does so smoothly, and if I want to break out the fangs, the car happily obliges.

@vetali remember that squeak? I ended up fixing it... 

 

Turned out to just be the slave where it insert into the clutch fork. I guess from us washing the engine bay out a little surface rust appeared at the tip of the slave cylinder rod and because it wasn't smooth anymore it was making a squeak from the tiny motions that the clutch fork makes when the engine is running. 

 

Easy fix was grabbing some lube and coating the tip of the slave rod with it. Since then, 0 squeak. 

 

I love easy fixes lol

[bcredeur97]

@Zodiark1593 I know for sure Ford used a dual mass in the ecoboost mustang. Not sure about the GT
