nitrous?

i was wondering how nitrous would effect a totally stock thunderbird, how quick am i going to go? and how quick am i going to blow the motor i suppose its all on how i use but what would you guys suggest? if i do get this i only plan on using it during drag racing which for me would be like once every two weeks or less.

thanks for your input

As I was told back when I was first discoveing nitrous:

It's not a matter of IF the engine will blow, it's WHEN will it blow. Make all the necessary fuel system upgrades and spray low volumes (75 or so ) and you should be fine, you need a chip if you go higher than 75 shot, but I would get one anyway. Use race gas when spraying.

Be careful and it "should" last. 1MTNCAT has had his Zex'd cat for like 5 or 6 years on the spray.

Knowledge is everything.

Read all the nitrous threads in this section, that'll start you off good.

If setup right you should not need race gas for shots of 100hp and down. For 75 hp you can get away with the stock pump and no chip. If you want a little extra saftey you can run one step higher on the fuel jet.

Mark, if you run the 125, how do you go one fuel jet higher, since there isn't a 150 zex jet(i think)

Well it depends on how much the the Zex fuel solenoid can handle and I am sure Zex can tell you what size jet to use. They use small solenoids and I don't know what the high end is with them. I know the NX solenoids are good to 300 hp shots.

Check with them but it looks like a 36 fuel jet and a 52 nitrous jet for a safer 125 shot and this is only for the dry kit. Also this is going to just about max out the stock 19lb fuel injectors when you go over 5K. I would stick to a 100 hp shot. That would be a 38 fuel jet and a 46 nitrous jet to run a little on the rich side which is what I would do. It is not worth pushing the limits with a 125 shot without much testing. Ask Steve for his opinion.

i read somewhere that zex's solenoids are good for up to 175-200 horsepower. the only reason they limit thier kits to 125 hp is because they're made to run on the stock fuel system.

Whatever you decide to do, be careful and do your homework. Remember, it's always better to have a car that's dead reliable and a little slower than a fast one that has trouble all the time.

you could expect to drop about 1.0-1.3 seconds off your 1/4 mile time with a 75 shot. i went from 15.008 to 13.756. all i added was a 75 shot and 4.10 gears. my car has more in it if i had some drag tires and if i could hit the nitrous off the line. i'd say its good for 13.4-13.5.

with a 75 shot(dry), I went from 15.8's to 14.1's.
The car was bone stock both ways.

I just ran a 13.7 from a mostly stock 15.5. 75 shot pnp'd heads, pi cams, intake, etc. I also had no traction and didn't shoot right off the line. Just to give you another idea.
