what gearing are you using, nytro supercharged

[extreman1]

Wondering what you guys are running for gearing on your supercharged nitro,s (xtx) I have 10 lbs boost looking for more speed.

go with 23t top and you should be good 24t is alittle much my mcx turbo nytro loved the 23 no matter what conditions...but the stock 21 is best for corner to corner trail riding on tug hill

gearing

any idea of the speed improvement? what mph can I expect?

 

[JP270NYTRO]

with the 23 your about 120-130mph on the long side.

As for now im running 19/39 on 6psi. ~155km/h topspeed. This year i'm aiming at 12psi and i might change back to the 21 if i feel that it tops out way to fast.

23 or 24 - 39 for fast trail use - ive seen 133 with my 10 pound nytro

Just went to 22t from 23 at 9lbs. The 23 was fast but I think the 22 will be the magic number.

Are you guys running pump gas at 9lbs? I went up one tooth as well with mine at 5-6lbs. 122 is common for top speed in around 2000 ft. I runs 105 in 1000 ft with trail studs spinning the entire track!

I would love to run more boost but it must be on pump gas and reliable!

23/39 would be the best gearing for your application.. You could run 24 if you really want top speed for the long runs but will loose some on the low end..

Last winter i ran 28/28 pulleys for 6-6,5 psi strictly on pump gas premium 92 oct.

This winter my goal is 12psi on pump. I have added a intercooler, extra tunnel cooler, head shim and 3 extra injectors with it's own efi system. With this setup i should be on the safe side!

Snowmaan you should be able to run more boost on stock compression . I just did the mpi software update this season, handwarmers inc. I'm running 25t x29b, Beggi fuel pressure regulator, cold air kit , and updated fuel pump. =9-10 plbs boost. I pulled my clutching down last year to run 6-7 lbs. Now i'm running the rpms up and so goes the boost.
