Ok, so there's a guy in our car group talks some mad e35 m3. So my friends all had this crazy idea for me to embarrass his 750 horse chevelle. All good and dandy up to this point. Except for the fact my racecar is a 200 horse beetle. But, being the guy is my best friend, I know he absolutely tanks at dig racing. So I need help in figuring out the best way to make my transaxle hold a hard launch with sticky tires. We're racing 1/8 mile. I have an AH code IRS trans that I'm putting a super diff and a billet side cover in. Anything else I need to do?

Add a few turns and a stop box. Done.

Get the flag girl to flash him right before the drop. Alternatively get a girl to tell him she's pregnant and its his.

Mid mount a twin turbo 4.8 LSx bolted to a built TH425 transaxle.

Forwarded your question to a buddy of mine who runs a bug pro-stock. I'll let you know what he says.

His bug is the closer of the two to the camera: https://www.youtube.com/watch?v=GSefsKsw24s

Good luck!

Thanks for not telling me just to give up. Anyway, I don't know any chicks that'd flash him off the line (unfortunately that'd work against me as well). And a pro racers help is more than welcome. What's a stop box?

Have him spot you some car lengths.

Should sound a little like Two Lane Blacktop:

Hot rod driver: How about fifty?

The Driver: Make it three yards, motherberkeleyer, and we'll have us an automobile race.

Pray that he smokes his tires on the launch.

Is it me or do most of the home-built fast Beetles have stock internals in the transaxle?

Maybe a really good clutch? Lightened (12-12.5lb) flywheel?

Gymkhana thing. Stop in the box without smashing comes or incur the wrath of the two second demons.

Hey, Shaun got back to me. He didn't really have anything to add to your setup but a super-beetle mainshaft (if you didn't have one already) and he recommended 388 ring and pinon.

Give 'em hell

You challenge him to a race and you pick the track... Then do something like autocross that will cancel out his horsepower advantage...

On a more serious note, p/w is your friend. For the purposes of this, I would absolutely slay this beetle. Gut it within an inch of its life. No fenders, no lights, no nothing. If he's pushing 3000lbs of Chevelle, and you're pushing 1500lbs of beetle, and he tanks the launch, you have a real shot at taking him down. He's going to have the big end on you for sure, unfortunately power is like that. You already said he sucks at digging though- so your key is at the light. Do whatever you can to get him as soon as it goes green. I think you already have a psychological advantage here, a big bad Merica car with quadruple the horsepower of a silly little VAG car... the winner should be obvious, right? Play into his cockiness. Get him to sleep on it as much as possible. The less he thinks about racing because he thinks he has the win, the better it is for you. The ONLY other advice I can give is MAYBE a small wheelie bar for traction (I have no idea if it'd make a difference, but if you had a skinny enough stick up front, super narrow front wheels, and no other stuff in the front butt, I can see it lifting) and a 50 shot dry for the top end (though it's only an 8th so it might not make a difference) and pray. The biggest thing I learned during my days of illicit racing was it wasn't the fastest car that won, it was the smartest driver. I was lucky if I made 250whp in my DSM... but I only lost twice, and both times it was races I knew i'd lose, and I chose em because I wanted to see the other car go. 90% of a race happens before the cars leave the line..... use it.

Give the beetle #53 and it should beat everything, even drive itself.

Too bad you live so far away from Massachusetts, I have an already built close ratio drag racing box that you could have for just a couple a hundred. All set and done and for less than you're gonna have to pay to have your own box built.

Oh, don't waste your money on an HD side cover, that isn't where they break. They bust the case open at the top when they go. TC

Is this AZN from Street Outlaws? Dude, just get your producers to build your car for you.

"TeamEvil: What would it cost to ship that trans here?"

Probably between $30 and $50. I checked earlier with UPS and actually removed the nose cone to bring it down to the required box size to avoid "over-sized" charges, but it was still kind of a lot.

If you're serious, I can check again.

Let's see. A 750 hp Chevelle against a 200 hp Beetle, and you want to beat him with a good, hard launch? Hate to sound like a negative nelly, but all the time and money spent will not beat a 500 hp deficit. My experience E.T. bracket racing tells me the best holeshot in the world is only good for about 100 ft up against that kind of horsepower.

Was this car dynoed at 750hp or is this one of those "my uncle has a Chevelle with 750hp" things?

For all we know right now, it's a 380hp reality check.

The reason I ask is that I was told a "story" of a Mustang his uncle owned with -funny enough- the same hp number and was "told" the car was deemed illegal due to "too much power".

He also told me the same "uncle" was doing a dumbbell pullover exercise so heavy that he tore his abdominal muscles completely from his pelvis!!!

Things are already changing up a bit considering mass/weight alone. The Chevelle would be twice the weight of the Beetle, so maybe even things out and take the Beetle hp at 200 and cut the Chevelle down to 375 relative hp on paper as it's moving twice the mass.

Add in the insane gearing in a VW drag transmission, the gear ratios clustered to all but eliminate RPM drop versus the more spaced out gearing on the GM trans, factor the limiting 1/8mile and you're getting kind of close to a race here. Plus the VW trans is loose enough that it can be hammer shifted by just holding the pedal to the floor and hitting each gear at around 4,500/5,000 rpm. Three fast hammer blows and hang on in fourth.

I wouldn't count the Beetle out too quickly. Then there's that fudge factor in the 750 hp estimate to check into.

Maybe? Kinda fun just to think about the YouTube video that will result.
