Re: Randy Mans DQ?

I'm sure that's rear tire 60' that car works very well!

Imagine if you could get a Stick car to 60' as well as an Automatic.

That 60 is probably with the rear tires. The auto guys are all on radials, what are they worth over the bias? The stick guys are sneaking up on radials with clutch tuning.

Mike, I stand corrected, though this was set not at the US Nationals but at the open.

The fastest A/S with the same engine combination (rated 5hp less) ran 9.821 at 3,370lbs. That's 240lbs difference and the stick combination is only .10 faster on the same track, on the same day. The answer is simple: there is plenty more potential in the big block, carbureted stick shift combinations. Regardless of other combinations in whichever class they are participating in - those cars have at least another tenth in them so don't let anyone tell you otherwise.

Humor me if you will as I partake in your paper exercise.

What would your LS car run with the same earned horsepower rating as the auto LS1, 342hp vs 381? That's 312 lbs, roughly 3 tenths. Let's go back to your class winning 9.80 a few years ago. With that 312 lbs you are roughly 10.10 or DNQ

What would the 2015 LS car with the same earned horsepower rating as the auto, 370 vs 401? That's 248 lbs, roughly .25 tenths. Let's go back to last years class winning 9.80 2015 LS car. With that 250 lbs that car is roughly 10.05. Matter of fact Ponville was there going high 9.9s in A/SA carrying that weight, so how much is left in the stick combo??

Re: Randy Mans DQ?

Dave, I have a 2015 LS Camaro, and the numbers looked a little off to me,
so I just went and double checked. The cars came rated at 365 HP. The
stick has only been nudged once for 5 HP, so it now 370. In A Stick it
has to weigh 3130. The automatic is probably close to where it should
be at 401 HP. The A/SA combo has to weigh 3378, or 248 pounds more
than the stick car. Using your scale, the stick should be around 25
hundredths faster.

Re: Randy Mans DQ?

I don't think there's anything you're saying Dave that is out of line here, you're pretty spot on with it all. With the current HP factors that J.R. shared, I do think that the stick shift 2015 Camaro is pretty darn close to that .25 faster than the automatic counterpart which does line up with the weight differential. During first round of the real eliminator the stick shift car ran 9.77 when Ross in the automatic was running 9.97 - it's definitely reasonable to believe that the stick car can run mid 9.70's with some more effort and time.

I absolutely believe the big block carb cars can run 9.70's and probably even tickle some 60's if they hit it right in a good session. I absolutely believe you guys could be the ones to do it with the power you make and how well you know how to make those cars work.

As for the LS1 that we run, the only part that isn't quite accurate in the description is the assumption that we are 310 lbs lighter in A/S than the A/SA when we ran 9.80. The fact is that we were about 175lbs under A/SA weight during those runs. Which I do think is pretty reasonable to think that we can run mid-high 9.90's in A/SA. We ran 9.98 many years ago with an automatic and we've made some notable gains in the engine side since then so I think that's surely likely. Do I think we can run 9.70's in A/S? I sure hope so, because I think it's going to take it to beat whoever comes in A/S. Getting to the current A/S min weight at 2,905 is incredibly unlikely unless I put a horse jockey in the seat and take out all of the ballast from the areas of the car that are necessary to make the car work. I don't know about the other guys, but I'd rather have a car that's pretty quick that I know I can get down the track than to have a very fast car at min weight that I don't think will make it 2 feet off the starting line.

Re: Randy Mans DQ?

After watching Mr. Hutto out west it makes me want to get my corvette out, build a 427 and come play with you guys either in A/S or the new 10,000,00 special race! Getting the Vette to hook will not be a problem. Hint Mr Hutto put a stick in that car and go claim that $10,000.00 prize!
