Dear Guys
Now I had a APS system 80 kps Boost + nitrous around 50HP Shoot and I'm running Low 12s
but now i get little conpfused on Boost and Nitrous
any one can Expland to me about this Question

Less Boost + More Nitrous = ?????
or
More Boost + Less Nitrous = ?????

Cause last time I'm try to 85 kps Boost + 85 ~ 95 Nitrous shoot
and my A/F was 12:1 so I think this is maximum I can have !!!!!

So what you guys think

Which is better setup on the Drag track

 

why use nitrous at all if you have the APS kit? The TT's are small enough that you shouldn't need n2o to spool them up and you can just raise boost till you get the desired result.

 

My Car is 5AT 2003 350z model
I need to get some nice 60ft time........
as you see my A/F is below 12:1 and EGT also below 840c
so I don't think I'll have Desired Maybe not

 

Well, honestly I am not sure why you would want to buy an AT then drag race... but anyway, I understand your final drive ratio is like 3.2 or 3.3 and you can convert it to 3.538 like the 6MT comes with (which is a recuction of around 6%), or even further upgrade it to 3.917 for another 10% reduction. Higher # means smaller gear, thus improved acceleration. You may lose a little top speed, but I assure you it will still be well above your max on a 1/4 mile stretch. This reduction in final gear ratio will get you through your gears quicker, and shift at a lower MPH.

Dunno which model you have, but you may also want/need to look into a nice LSD like Nismo or OS Giken. It would seem like your "horsepower" is enough to run 11's.

 

Thank's for your Advice ......
O.k now I'm running 6MT FD Gearing 3.58...
you think 3.917 will work on my 5AT ??
cause end of 1/4 my car shift 5 gear what do you think .......
