gearing +n2o question
 

hey i am in the process of ordering a new 12 bolt from moser, i am not sure what gear to run i have a th400 and i want to run the most gear possible, i have a 4000 stall, and bolt ons slicks and skinnys, lots of weight reduction, and a 150 dry shot i want to run 4.11's if possible but im not sure if itll be enough on n2o?
thanks for any input

Look in the 3.70 range and a 28" tire.... but every car is different...

it'll also depend on the amount of converter slip that setup will have. I would go 3.70's just to play it safe. If you still want more gear, you could always step it down to a 27" tire.

Figure out where you think the car will trap, max RPM for the engine, and what size tire you're going to run. With the little info you posted, I'd guess a 3.73 with a 28" tire and 3.55s on a 26" tire. This is assuming stock cam.

thanks guys ill probably end up going with 3.73's then

Why dry?

my brother bought it but sold his car before he installed it so he sold it to me real cheap, i read that a 150 shot is the highest you should go with dry so im gonna go with that and in a year or so im building a motor which will be a wet 300 shot

You can run as much as you would like dry... I wouldnt try to do it on a stock fuel system at all...

o well then i might step it up a bit depending on how much power i make, and i am gona get some 42# injectors, new pump and a fuel cell in the trunk, i read that the stock fuel rails can support 600 rwhp no problem(could be wrong again lol) but havent heard anything about the actual fuel lines
