4.8 Second 0-60!!!

[Demi]

An Cadilllac???

There is a big difference between driving your car hard and abusing it.

But as long as you have money to burn for out of warranty repairs, it's nothing to worry about. (headshake

Feathering the clutch causes it to slip, and in turn heat up, which in turn increases wear, with an upgraded clutch in my future, im not sweating it much. Flat footing does increase wear on the drivetrain, but this is also not the way i drive to work. I drive it like a madman at the track, as thats the only way to put down good numbers. If that means at 75,000 miles i have to rebuild the tranny so be it. To drive competitivly, component failure isnt an if, its a when. The realitity of the hobby. I like fixing stuff.

and checking and clearing DTCs, monitoring charge temps, monitoring AFRs, and Cat temps, voltage, injection rail pressure, short and long term fuel trims, knock retard, intake air temp, coolant temp, engine load, tranny temps, MAF voltage, % throttle open, manifold pressure, injector duty cycle, pulse width, ignition advance and being able to chart and graph all of those.

So yeah, s**** and giggles.

Rofl waffles.Yep its a great little device. Im really happy with my purchase.

The speedometer runs off the front abs sensors, if you unhook them the speedometer does not work.

Really?!?!? That would work, but seems like extra work. How does the car determine which wheel to use? Going around a turn each wheel is going a different speed. All the cars I have ever known have used the tranny for speed.

I think he summed it up with "waffles"

When you guys see numbers like that coming up, try and be realistic. 4.8 is the same as cars with a lot more power and a lot better grip. The '05 STi puts up that number, has AWD traction, and has 300hp/300lb.ft available in every gear instead of being boost limited in first and second.

Yes the STI has AWD and 300hp/tq but it's also a bit heavier.

With a few decent power mods the MS3's (power to weight ratio) is actually better than the STI. Granted it doesn't have AWD it is still a car capable of running fast 0-60 times.

Is 4.8 sec doable? Car and Driver got a "stock" MS3 to run 5.4 so why can't a Modified one run 4.8??

 

[tru-boost]

the DH is only as accurate as your cars speedo. and when you flat shift 3rd and get wheel spin your speedo says you are going faster than you are. our cars cant hit 60 in 2nd gear, and the graph never even shows 3rd gear on it. an accurate 0-60 run will have quite a bit of 3rd gear visible on the graph. its not an accurate reading ...sorry. that would be a solid low 5 sec pull though.

It's also not torque limited in first and second. In the first two gears we do not make full power. Because of that, we are down on power for 90% of the run to 60, making 210 lb-ft in 1st and 250 lb-ft in second. Besides that, my point wasn't a comparison to a specific car, my point was that cars that are breaking into the high 4's for their 0-60 times have significant advantages over our car, be it power, drivetrain layout, weight, engine management, etc.

Is it doable with a stock MS3? No. Comparing stock cars, .6 seconds is an enormous difference between 0-60 times. And where does the guy in this thread say his is modded? Am I missing something here?

 

[RocaLoca]

I agree.. a 0.6 second increase in 0-60 time is very hard to do. My "other car" has about 420hp to the wheels and I do the 0-60 in about 4.0 flat. it could be faster except mustangs dont stick to the road too well... =)

I am modded, but i think that we have established that the 0-60 was false because of the way this car reads speed. Im thankful the car is torque limited in first and second or my poor potenzas would have survived the learning curve. I think a 4.8 zero to sixty is possible, there are folks here that have posted 5.1-5.3 seconds with out wheel spin and we are just starting to learn what this car can actually do. I will however agree with you on some of the design being a bit less than what would be ideal. I understand that there have to be trade offs for the car to be affordable, but the difficulty fitting wider tires under this car shouldnt be one of them. Love the name by the way, huge fan of Ralph.

Yea, my only point was I think it was pretty obvious the number was false just based on the number, and from there you can go about figuring out what caused the anomolous result.

True. Far too true. This car can roast tires. Too bad it's front-wheel drive, but hey, what are you going to do? Wanna know something sort of scary? Go check dyno numbers for our car and then compare then to dyno numbers for the STI (run on the same dyno). The STI shows about 20% drive train loss, and puts up about 240/240. We show about 15% drive train loss and put up about 220/240 at the wheels. If we weren't so traction limited, we'd be much quicker in a sprint from a full stop.

I think a 4.8 zero to sixty is possible, there are folks here that have posted 5.1-5.3 seconds with out wheel spin and we are just starting to learn what this car can actually do.

If we can get rid of boost cut in 1st and 2nd and improve traction significantly enough, I think we can probably break into the 4's on a good run, but we've still got that problem of the third shift needed to hit 60 which eats away time, so it'll be close. We don't even really need power mods to do it, either.

True enough, since we are on this topic, has anyone tried running spacers to shove bigger wheels under this thing? I dont know exactly how that would work, ive never really looked into them, but it seems (at stock height at least) that rubbing on the inside during turning is what would keep us from running nasty big tires.

 

[CWPspeed3]

For these runs getting into the low 5's are those still the stock tires or is anyone running drag radials/slicks?

 

[MS3077]

Is there a way to predict your 0-60 by your 1/4 run?
I know I launched a 2.07 and finished the 1/8th in 9.0.

I wonder what my 0-60 time was on that one. 5.5-5.8?

Thats a good question, the last one i saw which was a 5.1 was on the street so im guessing street tires but i dont know type or size. The mods deleted it because it wasnt on a track.

 

[serialtoon]

Yeah, its got me wondering to which is why i want the camera in the car. I could feel the car surging forward hard with the flat foot, so maybe it is just lurching forward, but until a video confirmation i cant say %100 that the dashhawk isnt freaking out. All out flatfooting second just spins tires, but i think maybe 1/4 throttle would really help out. Ive got another concern as well though. The rev limiter does not kick in when the clutch is in, and i havent actually tested it with the clutch out. I know the dashhawk is off on rpms by as much as 400 at 6000rpm, and ive seen 7100 on my tac. Im a little concerned that if i miss a shift doing this that i could end up in 7500 territory. Also which wheel gives the speedometer its reading? If its the front, none of this can be given any credit.


I was launching around 2500 and pushing it up to 3000+ while feathering the clutch to keep it from bogging. After a few runs i could smell the clutch, so i stopped for the night. Id dont have it mounted permanently yet, but the lip on the dash close to the windshield makes it possible to wedge straight up and down between the dash and windshield, to get it out all you have to do is pull it to the right. Works out really well because its easy to get to and its right in my field of vision, which is handy because i use it as a shift light too. The cable runs great along the side of the dash, and looks like its suppose to be there. Pics later if i remember.

What does burnt clutch smell like? (im being DEAD serious here)

It smells similar to a burnt electric motor, or brake dust.

wow thats quite an impressive list there. I wonder if any of those are daily drivers..

Sorry about being off topic here, but would you be able to smell it from inside the car with the windows rolled down on a red light? (crazy)
