My boss takes us all to Mile High Nats every year, pays for food, beer, etc. I love getting loaded and watching racing on the company dollar. :mrgreen:

Aren't those Top-Fuelers cool?
The first time I went, it was between stages, so no cars were running when we got there. We sat down at half track, behind two tough looking biker guys, and as a dragster rolled to the line and did burnouts, those "tough" guys plugged their ears. I snickered, and probably said something about their manhood.
Both Top Fuel dragsters passed at full song, I had no ear protection. I thought my head was about to explode. WOW!
I plugged my ears for the rest of the day.

Whats your C5 running at bandimere?
It seems the "majic" number (at least last time I was there a few years ago) that the C5 guys were trying to exceed was 100mph. Yes, there were some up around 110mph with blower and such, but it seemed that the 100mph was what they were all trying to break.
Around 88-90mph 1/4 miles seemed about stock.

C5's should be trapping in the mid 90's at least. My little four-cylinder Mustang traps at 89-90.Quote:

Back about 5 years ago my friends 4.6 Cobra (300hp 4 valve) didn't trap 90mph. I have seen a viper post less than 90mph.
Now, if you have an SVO or a GT turbo (most likely both with more boost than stock) a 4 cylinder mustang is not putting down that kind of mph.
In general, speed is pretty consistent. ET can vary widely, even with car that have indentical hp/weight ratio. So much of a quick ET is the 60' time.
For example, I have a time slip showing an 11.855 sec 1/4 mile. The trap speed was 89.86mph. Those two numbers tell you something was wrong.
But in general, a full power run will net a very similar trap speed alomost everytime.

my 1961 VW has an aircooled 4cyl and i hit 102mph at 13.02
I bet it really close to stock....Quote:

There are fast vehicles. The ones that are most impressive are the true street cars that are fast.

91 octane on DOT slicks. i had to drive the car back from denver 80+ miles when a hub went out on my trailer and it never gave me a problem. it will not over heat sitting in traffic but i would not want to push it too long at a stand still being it is aircooled. it likes to be kept over 3000rpm for the fan to cool the motor.
as for close to stock :P
its a dune buggy weighing in at 1450lb with a 2110, turbo charged currently running 12psi, and a custom mapped GM EFI system. it dynoed 149rwhp and 152lbs of torque uncorrected

I like the turbo setup. It is quite nicely done.
So why is that when people start talking about how fast something is, everyone throws out things like "my 4-cylinder mustang" runs this, my air-cooled such and such runs that? People really like to throw out that they have 4 cylinder vehicles that are fast.
Are they trying to get an arguement? Are they trying to get someone to call BS then "prove them wrong"?
I just don't get it. Really some of the fastest true production cars (I am not talking "production" cars that are race cars that are made street legal in some other country and a minimum quantity built, but true production cars) are 6 cylinder cars.
Really, it doesn't matter how many cylinders or how they are configured. What matters is power, weight, traction, and gearing. The rest is just how you get there.
The little dune buggy weighing about 1500lbs and making 150hp will be about as fast as a 3000lb car making 300hp.
Also, when racing here (denver) people must keep in mind that its the actual power that the car makes here. That is why a C5 isn't as fast as people think. That 350hp C5 is only making about 280hp here. Take driveline loss and RWP is probably in the 240-250 range. That is a solid 15 second car with the weight of C5.
To break 100mph in a 3450b C5 (weight of the car and driver) needs to make about 270rwhp to break 100mph. That means the car needs to be about 50hp more than stock to break 100mph. Gaining 50 hp is harder than people believe.

i built a VW because it's not the same old thing, it just seemed fun. i get just as many head turns driving it as most exotics. i know it could never beat most suped up V8's but its neat to have it run 5 times the HP of what it was designed to produce. it seems like everybody has a "fast" honda or Mustang. i have yet to have anyone tell me they have a car like mine.
