Anyone have any? I am looking for stock times and also times after mods were added. Any Nitro Pro5s out there? If so what kits?

well.......there is a current thread in 'dyno & 1/4mile times' but i'll post it again here.

16.704@77.283 in my P5 (stock)

 

I think that LooseCannon is full of bull. MP3 are barely running those times ( stock ). For his to be stock there is no way in the world that he is running that time. 77mph doesn't = 16.7 no matter how you calculate it. Sorry LooseCannon. Don't think so.

Thanks guys. I'll check it out in dyno & 1/4mile times.

completely possible I would say. NOT a whole lot of difference with the 10 extra horses. And as for the time = mph. I've seen pro cars blow a motor @ 60ft. and still cross the line with 130mph trap speeds and times of 13sec.

 

Trying not to be biased towards Protege5
16.7 seems to be reasonable and low trap speed can be explained by engine running out of steam. 2.0 liter has very strong launch in 1 gear which is redlined at about 30mph and picks up well in 2 gear but after 4500 rpm it just sucks and I hate that-like hitting invisible wall, because car just won't accelerate as strong as before. 74mph is 3 rd gear, not sure what is rpm
MikeD and PseuX have 1.8 BP which does exactly the opposite-weaker low end but it will pull all the way to 7000 rpm.

This is bull, no questions!

Psuedorealityx,

Yeah well the P5 is heavier. Has less horse power and the rims aren't THAT much heavier to where the car is faster than an MP3. You are nuts. And for the front end causing too much drag... look again bud they have the SAME front ends!!! Im sure you have taken a MP3 to the wind tunnel to test the drag on that wing too. Yes I believe that the wing is there for just looks and like all wings causes drag. Still no P5 is beating an MP3 stock. I guess Mazda should just take the MP3 out of the lineup and offer the P5 as the sports model since its faster. Im done

 

Which makes the them some of the heaviest wheels Racing Hart makes.

I find the 2.22 sec 60 foot time more remarkable than the 16.7 sec 1/4 time. Road & Track doesn't test on a drag strip, doesn't speed shift, and probably doesn't hammer the car on the launch.

So, it's entirely possible that under the right conditions that someone could beat Road & Track's time and do a 16.7 sec 1/4 mile, especially if they were willing to thrash their car.

Being able to spin the wheels is one of the secrets to getting a good 60 foot time. When I had 205/50-15 Michelin MXX3s on my '90 Protege, I was able to pull 2.3 sec 60 foot times at Pro Solos (not a high traction starting surface). When I changed to Falken Azenis in the same size, I lost 0.2 sec due to having too much traction. If I wound the engine high enough to keep the Azenis spinning (until the revs got high enough to prevent the engine from bogging), the tires would bounce.

 

The engine mounts are still fine. It was launching at 6k rpms that it couldn't handle, not with a 35lb tire and wheel combo. I was doing what Will said: "You have to overdo a start once in a while to know where the upper limit is."

 

Ive ran the 1/4 in my 01 ES GT (2.0) and with some intake tuning it ran a 16.6 @ 79.2 mph. The track here aint great and its completely acceptable. Those are "magazine" times. Anyone familiar with their car could pull a better time and remember these tested cars are usually not at peak hp usually being brand new and not broken in.

 

My god, lauching at 6000rpm.... that must have been a tad violent....although i am in no way an expert or anything here, but i found (with my particular set-up anyway) that a 3500-3800rpm lauch provides the best results. Enough Wheel spin as to not cook the clutch, although it does slip a bit, no wheel hop and decent 60ft times.

 

At most Pros, I found that 3000-3500rpm was a good launch rpm. Got the tires spinning, kept it from bogging, and got great 60 foot times (staying next to a Impreza is great fun ) And as far as I can tell, my clutch isn't slipping when it's fully engaged.

Then I got the 205/50-15 Azenis'. Too much traction for my HP-challenged Protege. I found myself launching at 4500-5000rpm, and while I'd get wheelspin, they'd get traction too fast and the engine would bog at about 20 feet. Will suggested that I do a crazy RPM launch, so I tried 6000. And got huge wheel hop.

If I go again, I'll have to try running my 195/50-15 Kumho 711s and see if I can get a good launch without the bog.

 

I have Falken 205/40/16's and i launch around 4. its the just enogh hp to get you going and the torque is almost peaking, as to not let the engine bog. Polyurethane or filled motormounts will reduce wheel hop if not eliminate it.

 

Are filled mounts illegal in SCC Autocross events or even polyurathane mounts? Then it seems off mine are coming

 

I might be corrected here, but i think that would just move you up into a different class. It's the STS class that they are not allowed in.
