I don't know anything about that....I guess if someone buys a drag engine and sets it up with stock gearing on a slippery track there may be an issue....... but taking a stock or near stock Elite 5 and putting on a 9853/41001 isn't going to make it some tire spinning monster that uses its fuel tank in 5 minutes..... coming from a 2096/41021 its going to give the engine a stronger feel throughout the powerband with a noticeably better top end run out and about the same fuel mileage..on a track needing more power it may even get better mileage.... If your having trouble handling a stock Elite 5 with a 2096/41021 then you probably wont want to go to one of the better performing 2 chamber pipes....but if your like some guys and the 2096/41021 isn't enough for you then you can easily find more power with just a basic pipe and manifold swap....
