I don't know what would be a better performance upgrade. I am a little scared of getting NOS, but what do you guys recommend? Should i get the Nos setup or go with a bigger pulley to get more boost. I am currently on a 2#, chip, FASTair intake and filter kit, FT valvebody.

 

Go w/ a 5 or 6# Lower (I recommend a 5).

smokin SVT what are you running with those mods?

 

I would spray that pig before I started to play with those pullies.

good luck,

I disagree. Using N2O would be more app to do more damage than a 5 or 6# pulley. Plus, w/ also adding in a chip on top of the pulley, you'll have nearly the same hp as a 75 shot of juice, and def. near identical tq #'s.

Best difference is that the N2O hits hard all at once, where as the bigger pulley/chip combo doesn't, hence the last combo will prolong your rods (amongst other internal parts), and tranny versus going w/ the N2O.

 

With a pulley, you'll never have to refill a bottle. You will have power all the time. Go with the pulley.

I am currently running 12.9's consistantly, i'd be more than happy to sell you my 2# pulley if you become interested once i get a bigger pulley.

 

or....you could do a pulley & nitrous !!!!

but, thats just my opinion... some people think i am nuts!

Actually, if you use a nitrous management system such as Jacob's Nitrous Mastermind or similar type deals, the nitrous doesn't hit all of a sudden. Such nitrous management systems will gradually increase the amount of nitrous being used depending on what rpms you are running. For instance, a local v8sho guys was running 75hp shots of nitrous and he had it set so that it starts increasing the amount of nitrous starting with 10% at 2000rpm, and gradually increased it to 100% by 4500rpms.

 

I give another vote for both... Im about to put a 50 shot on my truck along with my 5lber!!

 

just a little fyi on how the progressive controllers work.

The percentages that you set are based on the maximum flow of the solinoid. So first you have to know the flow of the solinoid. We use NOS Cheaters (max 250hp) so here is the conversion of percent = HP of them.

20% = 50hp
30% = 75hp
40% = 100hp
50% = 125hp
60% = 150hp
70% = 175hp
80% = 200hp
90% = 225hp
100% = 250hp

So, if you have a 75hp shot in the system and you set the initail percent to 20% and a build time of 2 seconds to 100%, you will actually be at your 75hp level way before the 2 second build time.

Some people make the mistake of thinking that the percent is relitive to jet size. (as an example) 100hp shot, if they start at 25% they are starting with 25hp or 50% would be 50hp. This would only be true if the max flow of the solinoid was 100hp.

Hope this info helps...by the way we use a 4lb pulley and a 150 shot. It seems to be working pretty good.
