i just invested in a convertable orange Z28 i was just wondering what size of a nitrous shot will they hold safely ( with out damaging anything EVEN OVER TIME ) thanks for the info

 

150 if u tune well, 75 if tune crappy, none if u dont

 

when you say tune you mean what because im going to run a wet kit and the extra fuel is added along with the nitrous when the button is hit?

 

u can tune using the jets, but i dont prefer it. this means u check the spark plugs, particularly #7 after a run and look for signs of lean/rich condition and change the fuel jet accordingly. however, this does not affect your timing, and factory tunes have plenty of timing, too much for me. I would recommend a dyno tune to ensure the motor will last.

 

ok thats how i will tune it anyway because i have a good friend who can get me free dyno pulls thanks for the help

 

do u have a means to adjust the timing? thats the biggest thing here

 

yes i know your supposed to retard the car uppon using spay. but that will all be taken care of when i can afford the killer ignition box ive been looking at.

 

I dont recomend over a 125. Yes you can run 150 with good tuning safe. But i like being more then safe thats just me. Some guys havepushed well past the 150 mark on stock bottom endLS1's but theydont leave any room for error and personaly areon life support in my book.I would say 150 is probaly as far as you want to gowith good tuning.Invest in all the right safty gear and spend some time on the dyno and you should have no problems with a good wet set up. Specter can point you in the right dirrection if you need any help.

 

ignition box? I hope u arent looking at the 6ls from MSD. i tried that thing out, it has some funky timing curves, with timing that advanced through the rpm instead of retards. it went from 20deg at low rpm to over 40 at high, which is the opposite of what u want if u like ur motor. so all of the chips that come with it are junk. also I could never get my cam and crank PS's to work.

the stock ls1 ignition is good for about whatever youre going to throw at it. I wasted money on an ignition box, lemme steer u away from there. ud be better off buying a handheld tuner or HPtuners/EFIlife or something like that

 

i was told about hp tuners but i dont completly understand everything you can do to your car with it do you know? and then is it worth the money because they are pretty expensive?
