that just sounds crazy, but hey whatever works. wouldn't little sand particles break off?

 

yeah, actually it works really well.

I did that on my old top-fuel civic... I use a really fine grain and put big straws threw it to let the coolant flow... Worked really well @ 20psi for about 2.2456 seconds, and then everything blew up.

 

And if your making too much HP and your gears start to grind ... you can get rid of it by cramming some wood shavings into the tranny.

 

but why? (insert shoulder shrug smiley)

Personally i will never buy anything that needs to have a website like an infomercial.....they dont include the price of the stuff...i dunno...it looks like a nice scam to me...this clause at the bottom of their website really makes me want to go out and use this product
