You know, the way I read the post you are talking about was not as a claim that he could go 178MPH. I understood that he thought this was a more appropriate theoretical top end than was 153. As for the tracks you mentioned, I certainly am going nowhere near 178 on any of them (I've drive about half of them), but I can see 153 easily being an issue. I hit speeds right about there at the Glen, Pocono, VIR, and even Summit Point. I'm sure I would easily be up there at Road Atlanta if I were driving my car. And keep in mind that my car is pretty much all stock, other than a downpipe - at least it was at the time.

My point is that I didn't consider 178 to be a speed that he planned to acheive, more that 153 was too limiting. Just my $0.02 .

I think that once you get above 130 mph or so, it's really hard to rely on the accuracy of the speed calculators. But unless you actually do it, that's all most of us have to go on.

Paul, what happened to your avatar?
RICE RACING actually has a good formula using Cd numbers which will tell you how fast (aerodynamically) your certain car can go with X HP

in a 2nd gen 390Hp at the flywheel (it think) is enough to propel you to 300KPH

this formula says a 1st gen should be able to do 330ish KPH with the HP RICE RACING'S motor is making and he is running outta gearing at 8800rpm in 5th gear at 320ish KPH

Cheers

I was helping Daryl with his, but he needs 100 posts before he can use it.. I'm going to use a new pic for my avatar, just haven't gotten around to uploading it

Here is all I'm saying...

153 mph would not be enough for me on the street. Frown if you will, but any close race with a high powered car will not be settled at 100; the winner might not emerge until well up into the speed range. I raced another RX-7 back when my car was still twin turbo, and we were dead even up to the top of 4th at which point the other guy lifted and coasted. That was about 145 mph, so you can see that if we had kept in it, we would have been past 153 pretty fast.

I will probably never need to do 178, but I can assure you the car will do it even with the shitty stock 5th. I've had it up to 160 about a dozen times and it wasn't showing any signs of petering out.

Anyhow, I agree that for track use, 178 may not be realistic, but hey I drive other places besides the track. I'm just trying to improve my 5th to make it a useful gear on the highway.

A friend of one of my employees was killed this week in a street race during the middle of the day!

And then I have to go and read this:

Is there no common sense here? When will everyone learn? You guys must all have jobs with decent income, requiring a level of intelligence that should lift you beyond the lunacy of street racing, right?

Take it to the track! [/rant]

I have to second that motion. Exibitions of speed on the streets is not racing. unfortunately these acts on the roads bring a bad image to legitimate racing and racers. I would hope that everyone could see the stupidity of running a car on public roads in excess of 160MPH. a pothole could cause one hell of a wreck that could kill more than just the "racers". racing should be done on the track with proper safety precautions taken. this helps all the people who must work to support their racing get to work on time and home from work with enough daylight left to fix their race cars. keep it on the track.

Hey I do my high speed stuff by myself with nobody around... usually very late at night.

If there was a track closer than an hour away, I'd never take my RX-7 out on the street.... But there isn't one.

High speed driving at night? That makes lots of sense also.

Well then how do you qualify your earlier statement about racing other high-powered cars? Here it is:

153 mph would not be enough for me on the street. Frown if you will, but any close race with a high powered car will not be settled at 100; the winner might not emerge until well up into the speed range.

Sorry, but it doesn't sound like late night cruising alone to me.

If there was a track closer than an hour away, I'd never take my RX-7 out on the street.... But there isn't one.
Sorry, but that is lazy, rationalizing bullshit. The two closest race tracks to me are 1 and 2 hours away. You don't see me jetting around town in the middle of the night at 140 mph, just because I'm too lazy and undisciplined to wait for a track day. Sorry if this sounds harsh, it's not directed entirely at you. I hear the same line of crap from my customers who buy race gas for their street cars, and it's always the same.

No one is around when I do it, so what's the harm?

I never put anyone else in danger.

The track only runs Weds. and Sat.

The track is too far away.

Then I have to buy a helmet too!

The overriding fact is that the street racing crowd is too self centered and egotistical to have to play by anyone else's rules. Maybe they think of themselves as "outlaws".

That's not really street racing if you're going that fast... that's more like "open highway open-air dyno pulls", no racing required, just floor it and see who has a better power/aero ratio.

Basically, more dyno queen nonsense.

Only 1 hour to a race track sounds like a good deal. closest track to me is more than an hour and a half towing. regularly travel 2-3 hours to alternate race track and I have towed more than 8 hours before to get to a race. I hope that you never encounter a regular citizen on his way to work while you are out by yourself "racing".
