I am sick and tired of hearing idiots say wheel spin is good, has anyone else had someone try to tell them lighting them up when you launch is so much faster? with wheel spin you lose ground, am i right or an idiot also?

Depends where you're racing
Street racing on street tires: some wheel slip is good to help prevent losing too many RPM's
Mash throttle=massive burnout (most), go nowhere, but looks sweet
Baby it=No spin but stoplight to stoplight times suffer.

Track racing on drag tires or slicks: no wheel slip preferred
You can mash the throttle much harder depending on power, application, and skill level of course.

Dead hooking will break your stock rear end if you're making enough power....

The top fuel funny cars and what not actually spin for a while when they launch....

Dead hook also means quickest times, if you spin alot you can still run the same MPH but a slower ET

In certain situations, its better to spin just enough to keep from bogging, but not enough to blow them off, rather than let the car fall flat on its face. There is a very thin line to hold while tryn this though.

In conclusion,it is more beneficial to hook up right off the line.If you have serious problems getting traction,it could mean the difference between a 12.5 second car and a 13.5 second car.By the way,funny cars and top fuel really are a completly different beast.NHRA top fuel really have no choice with wheel spin initially.I dont think there is any tire that will hook up with 7000 horses of nitromethane powered engine off the line.If they did hook right up I could see them slamming directly into a wall(lol).

It's the same philosophy as in outboard motor boat racing. If you drill holes on the leading edge of your prop, this will cause hub exhaust to reduce density of water around the prop, allowing it to spin faster and rev the engine. The end result is a quicker hole shot. Once a certain velocity is reached (less load on the engine due to overcoming of inertia), the force of the water over the holes overcomes the force of the exhaust coming out of the holes and the prop now bites.

YOUR RIGHT. If your on the street about to race wheel spin is bad. If you have wheel spin you loss traction. i have lost raceS because of 2 much will spin.

I like to watch the NHRA dragsters going down the track and halfway down they light the tires up. Thats crazy horsepower, I think once you're over like 2,500 hp it should be referred to as one whalepower. Then saying it has 2.5 whalepower. ***** nuts. Then once they get back to the pits they have to tear down the motor and put it back together, most of the times they loose atleast one cylinder, once again, that ***** nuts.

Whalepower! I think you are on to something. My car makes about .25 rwwp!

Top fuel cars are mind boggling. It takes 1,000 hp to turn THE BLOWER.
