Bandimere track day anyone?

[JasonFRC]

Friday June 8th.

An all day test session with a 100 car limit. Most racers can do at least 20+ runs. Assuming you don't break anything!

This event has been going on for several years, put on by a couple local clubs.

BTW: that's my car on the web page!

I'll be there!

[The1andOnlyKC]

I will bring my '93 Ford Taurus. :roll:

damn too bad I didnt have my Mustang Running.

...damn too bad I didnt have my Mustang Running.


yeah, I'm STILL waiting! :roll:



:P

[shrapmetal]

$80 is fairly expensive. oh well i might be in. i need to get my VW in the 12's. right now my fastest run has been 13.02

[Asha'man]

Probably not gonna work for me due to date and cost, but you can usually see me at Club Clash. I'm gonna try to make some T&T nights on Wednesdays this season as well, and maybe race on All Ford Day.

They still have club clash?? I was one of the founders of that glad to see it still is going. I was also one of the people who helped create the stick shift class and I don't know if it is still going or not.

I wish I could come but my car is parked and for the time being it is permanent if and when I can do it again I will be there. :cry:

You all grab some gears for me and say hi to Johnny. :cool:

[Phillygunner]

No Test and Tune for me. Sporty and the gang got rid of PRO BIKE.
Oh well, you guys have a good time.

As soon as I pick up a few good lookers in it you can barrow it for a night.

Yep, CC is alive and well, and so is the Stick Shift class. Some of my buddies have done SS; I may do it this year if I have the money and time since I do have a car again. Were you with Corvette Connection when CC got started, or how'd that work?

I thought you already had one ?











putting the thread back on line...

a whole bunch of us from work used to go to the Mile High Nationals every year.... I haven't been there in about 2 years..I met MR. John Force last time I was there. (I'd like to "meet" his daughter too) :twisted: ..

I like Top Fuel and Pro Stock. If I was to have my own car, it' have to be in Pro Stock.

[Asha'man]

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:

[JasonFRC]

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.

[DanaT]

Unless you little 4 cylinder has a turbo with a decent amount of boost, I doubt it is trapping nearly 90mph.

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....

My only questions is: is that on true street tires in true street trim (i.e. 91 octane fuel, will the car idle in rush hour traffic with out over hheating, you can drive 150 miles away and drive back, can you drive the with the tires on the vehicle to the track, run, and drive it back home).

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

-Dana

[shrapmetal]

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

[DanaT]

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.

[shrapmetal]

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.

See sig. ;) Not trying to start shit, just saying that I did trap close to 90mph last year on a 15.92 pass. The trap speed is good for low 15's, but my driving was obviously only good for high 15's. Trap speed is what indicates power, assuming nothing goes wrong on the run, and is a key part of the information about a pass. Unfortunately, most people tend to omit it and just say the ET, which really doesn't mean that much by itself.

Elevation or not, a C5 should trap in the mid 90's based on horsepower alone.

[al_g]

I've been to 3 or 4 of these events and highly recommend it to anyone. The price seems a bit high until you look at cost per pass. It has been two years since I've had my Camaro out there but at that time 3-4 passes on a T&T night was typical which meant about $10 per pass. I went easy and got around 15 passes which is somewhere around $5 per pass.

I'd be going but there isn't going to be time to swap my six speed for a TH400.

[DanaT]

High High ET/ High MPH is a common trend on turbo cars. They are hard to get off the line. The problem is compounded with elevation as the turbo takes longer to spool up as less off-boost power means less exhaust gas velocity whihc mean slower spool up. Turbos tend to spike mush harder at altitude.

With a solid rear axle in an SVO and, ability to get lower gears cheaply, and availabilty of selecable lockers for the ford 8.8 (assuming you have an 85.5 or 86 SVO and not an 84 or 85 which used the 7.5 inch rear), you could actually make the SVO launch well for a turbo car.

The one thing to keep in mind that going just a little bit faster takes a whole lot more power. If you see a car trapping 90mph run ap against a car trapping at 100 mph, it looks like a slaughter.

I wouldn't mind getting out and running, I just don;t know if I will be in town or not. Also, with a 2 year old, the wife isn't too keen on me racing anymore. Racing also gets expensive.

-Dana

[Asha'man]

Turbo cars are definitely hard to launch. I attribute most of my crappy ET's last season to the fact that I was bogging the car hard off the line on every run. I have a lot more seat time in it now, so hopefully I'll be able to slip the clutch just right to load the turbo and leave under boost without blowing the tires off.

All SVOs had 7.5 rears, but they came stock with 3.73s (except in '84, I think) and a trak-lok, so that's pretty much good to go for a while. The gradual torque load with the turbo four (as opposed to a V8 car) helps to make rear ends live a bit longer, lol. I did put in a set of H&R SS springs, though, so that's not going to help the launch much.

Hoping to get my exhaust finished up fairly soon, too, so that'll help quite a bit as far as power. I can feel the stock catback just choking the car.

[DanaT]

Heres the trick.

Launch at 5000rpm....you wont bog.

-Dana

[DanaT]

This is bothering me.

I thought the 85.5 SVO got an 8.8, quadshocks (instead of hop bars), 205hp (instead od 175), a fuel selector switch, and bold new headlights...

heck yea! wheels up, tires slip 2 maybe 3 times and your gone! :P

Actually, I have been that crazy (or even more).

-Dana

[shrapmetal]

i always launch between 4500 and 5000. my whelliebars keep the tires about 6 inches off the ground and transfer all the wieght to the rear. i found i have to adjust tire pressure to slip the tires just a bit before they catch or i'll bog down.

[Asha'man]

Lol no, I won't bog....but I'll sit there and send my tires up in smoke. :mrgreen:

All SVO's had 7.5" rears. Otherwise you're right, except that I think quad shocks started in '85 and possibly some late '84s, and all cars had the premium switch.

[DanaT]

Naw.. you won't smoke the tires. Just learn to abuse the clutch...

But good luck, turbo cars are hard to launch. I have prooblems when I have been to bandimere with a turbo car. Great speeds, crappy times. I don't race often or seriously any more.

-Dana

[JasonFRC]

Eh.

Turbo cars aren't hard to launch if they're AWD!

On street tires my old Talon repeatedly did 1.69 - 1.72 60' times. There are so many tricks now to build boost at the line, even in manual transmission cars.

I used to rev to 5k, and start "popping" the throttle to WOT as fast as I could, with the right timing, I could launch under WOT as the third yellow illuminated. (sportsman tree). I would pretty much sidestep the clutch. I let the tires take the abuse (wheelspin). It worked well for me and my setup.(380 hp at the wheels)

My best was a 12.33 @ 111 with a 60ft time of 1.68.

My Vette? Heh. Since I can't launch a rwd car to save my life, it wasn't pretty.

I *think* I ran a 14.6?? @ 100 mph. My 60 ft time all night was 2.2-2.5 seconds!

I leave my Vette largely unmodified. I like that I don't have to watch gauges and tear into it every weekend.

Maybe I'm getting old.

So how many trannies did you go through when you owned the DSM? :mrgreen:

One rebuild actually.

My younger brother runs 10.6@139 mph in his '90 Talon.

He has a supply of used transmissions and transfer cases he dips into quite often.
