This is exactly what I mean by freak. Also some transmissions, rear ends, etc. will be a little more efficient than others because of normal manufacturing differences in bearings, housings, etc. Some cars just run a little faster than others all things supposedly being equal.

 

Bob, I also disagree with you about saying the dyno is a tuning tool, nothing more nothing less. The dyno gives a very good guess on how fast a car will be (by also taking into account weight, aero drag, gearing, etc). It is not the end all be all of how fast a car is, but a very good indicater. If what you say is true, then a 500 rwhp car may lose to the same 100 rwhp car!

 

Ok. I'm not making sense - as far as you know. I have absolutely no issues at all with that. In fact, it makes me feel a lot better. Thanks. You are correct - I don't believe it. Further, I think it is absolutely ridiculous to think that 10 identical F-body's with the same driver, track, etc will have ETs and MPHs that are 1/2 a second and 5 mph different respectively. That's ~50 HP difference. Bologna. And your credibility just went into the toilet, IMHO.

We shall indeed disagree.

Why do I need something to tell me what I'm going to run in the 1/4? Why not just go do it? Dyno's don't go down the track. Cars do.

That statement makes no sense at all.

Have fun with yourself.

 

I said ALMOST a half second and 5 mph. I don't use the dyno either. If that statement makes no sense to you, then I feel sorry for you. It's not that hard to comprehend, really.

 

Sounds to me like you could have a aftermarket torque converter. I don't know of anyone who can stall and LT1 up to 2K RPM's on a factory converter.

 

Steve, I have been racing and driving in the real world for 15 years as well, and there are differences such as mileage, options (that add or subtract weight) rear gear options etc that can vary times, and no driver is going to be able to drive a manual car the exact same down the track every time. Not even Evan Smith has been able to do that in the many years I have read MM&FF. Hell, it's hard for me to do the same in an AOD car. I've varied a half second and 2-3 mph on the same night shifting at the exact same points and launching the same.

 

This statement from you really suprises me. Coming from a guy thats always talking about beating 310 rwhp ls1's with his 240 rwhp mustang. You have said many times that the driver makes the diffrence. You are always talking about how you take them off the line. You cant have it both ways. By the way, you can tune your car for the dyno or for racing. Making big HP numbers on the rollers does not mean you are going to put it to the ground or shift great at the track.

 

Agreed. But I still believe in factory freaks, factory dogs, and average cars. I've driven 4 different bone stock 6-speed LS1 cars. All of them were the ones before the LS6 intake. One of the heaviest, a fully loaded SS was a freakin animal. Another one a 6-speed mid option car was pretty weak. A stripper Z28 was really fast and a Formula was so-so. Same with 5.0 Stangs. They vary a little too, even with same option cars.

 

You have your facts wrong. I beat (2) 285ish rwhp LS1s (stock automatics) with my 250ish rwhp Stang. I rip them out of the hole because of the tires, and none have been able to run me down yet. They may have been gaining on me slowly, but I didn't notice because of my 4-5 carlength lead. I am looking ahead concentrating on the road instead of on them. My car's raceweight is only about 3220 lbs. The LS1s I raced weighed about 3720 and 3580 lbs. Their power to weight ratio is not good enough to catch me with my lead, thanks to the tires. Of course driving well helps. Of course I can take them off the line when they have street tires. What two ways can't I have it? I have been speed shifting for 15 years. I can put all my power to the ground no problem with these tires. I am kinda shocked too about the LS1s. I am going to race all the stock or near stock ones I can find and will report the facts every time to you guys.

 

The seat of the pants is the world's biggest liar (Butch Leal, former Pro Stock Racer).

 

True, but i've seen identical new cars trap 4.5 mph and 3 tenths different on the same track, same day, same driver and driving style. Some cars are just stronger than others. There are no two cars exactly the same.

 

Uncle.

 

Ding..Ding..Ding..And in the 15th round steve y knocks out bob cosby with one solid punch.There are no two cars exactly the same.ROCKY..... ROCKY....ROCKY......

 

Jr, I'm glad you agree with Steve rather than me. You have no idea what you just did for his credibility.

And you also need a reading lesson (or perhaps another shot at the 3rd grade)...nobody ever said that any two cars are exactly the same.

 

My stock 2002 z28 dynoed the same day as 10 plus F-Bodies and mine was somewhere in the middle. The stock 2002 cars that were running that day pulled a 305, 307 and I believe a 298 all in RWHP each car had about three pulls and thats the best of what they got for the day. When it was my turn, I was after the 307 I pulled 315 and 314 with a 332.5 and 332.9 foot pounds. I am completely stock and so were the other two, I also saw a 2001 ss with the 345 H.P package, headers, catback, lid and I think a tune pull a 317 RWHP with 321 foot pounds....what the hell?

Thats just variatons I saw on the same dyno within three hours with three almost identical cars (Except the SS) and the temp may have changed a few degrees but not enough to skew my numbers off, it was freaky...and yes they named it the freak.


Sorry all 6M's also All betweek 25 and 35K miles
