After my run in with my last boost setup and while currently rebuilding it a question arose in my head. I am working within a budget and am thinking about doing a TD4OH 15G intercooled greddy kit on my vitara setup, but i dont think it will support the power range i am wanting. My question is would it be efficent to run say about 10 to 15 psi (if kit will support that...) and spray a 50 to 100 wet shot on it over the full rpm range? If so how should i tune for this and how much more timing should i pull from it ? I have searched and found only that most guys are using nitrous to spool bigger turbos and fully understand the concept i am just curious on how it will react with the boost. any help would be greatly appreciated. thanks in advance

 

noob question too but lets say that a turbo is good for 250 hp. You get every tuned out and make about 250 hp... then u spray a 100 shot on top of that. I know that the nitrous has to have some turbo, but what exactly is gonna happen? is it going to raise the boost because the motor is now doing more or would it be unefficent because isnt rated for those kind of power levels? on another note i am curious about the fuel pressure.... if the engine is under boost wouldnt the fuel pressure be higher thus giving the motor more fuel than normal from the fuel solinoid?.... im thinking too much i need to go smoke a ciggrette

 

anybody ?? i knoe theres some guys in here with experence in this kind of stuff......

 

it wont raise the boost.

it will add more oxygen (the part of nitrous you want, cause that makes more power)

nitrous makes really cold oxygen also...which is good for an overworked turbo (pumping hot air)..

if its tuned for the power, it should do fine.

 

Thanks for the input.
I plan on tuning it myself ....i believe (prob. wrong) and from what ive read everyone says just pull a few more degrees from it and the fuel should for the most part take care of its self ...i guess its ok if the afrs look good and no det. right ? haha i hope so.
Anyone else have any input? i planning on dumping the money into this setup i havent had any negative inputs yet.

 

what range are you looking for??
i made 240ish whp on a greddy kit with my vitara set up..
8.6 in the 1/8 on street tires in a coupe

 

i was shooting for the 300 range ....gotta lug those 2 extra doors around haha
