I have a 91 ford mustang cupe its all stock besides 4:11 and all the little add ons...and i was going to spray a 150 of NOS into my car..I have allready upgrade my hole fule system with 24 pounds injectors and a 255 fule pump.. I just wanted to know what do i have to do be for i use the NOS...Do i have to do anything with the timming, spark plugs ect...Please HELP

 

I wounldnt spray 150 on a stock motor. Just looking to blow sh*t up.

 

Nitrous will be fine on your car, but you need to make sure you are ready for it. You already have the fuel pump, you need to back off the timing, I would say in your case set it at about 10*. If you here any pinging at all STOP spraying back it off thetimingmore, you should be ok at 10* though. On your plugs, run one or two sizes colder plug ang gap it at .040.

 

I wouldnt run anything over a 125 on a stock motor......

 

If you have free flowing exhaust, plenty of fuel, good timing, 150 will be alright, Ive done it, seen it done plenty.

 

i run a 125 shot on the street and a 150 RARELY on the track....150 is not too safe....mine isn't a DD, so if it blows it blows....

 

I'll say it again for your benifit. If you put a 150shot to your stock 302, make sure you save me the hood and oil pan from after you spray it. That way I can put it in my shop so everybody can see what happens when people get too nitrous-happy

Whatever shot you decide to use, retard the timing 2 degrees for every 50hp shot, get a good tune, and use a wet kit. You should be ok, but 150 is pushing it a bit.

 

i wouldnt on a sn-95 with those hyper pistons they have either.but on a 91 fox with forged pistons and connecting rods.. then i wouldnt wory about it. if youre car is tuned right and you have all the safety equip for the nitrous and have upgraded everything that is needed to be upgraded i dont see why it wouldnt work fine and be reliable.

 

thanks for all the info guys.. I make go for only 100 shot... By the way i have a dry shot... Can i still do a 100 shot....
