110 will easily get you to 100 shot of nitrous and 125 shouldn't be a problem.

rollingchevys

i have 100 shot on the car now and runs real good on 91oct but i was thinking maybe 100 oct would be ok for my 125 or maybe 109/105 race fuel

I would say you should be fine but I would read plugs. You are certainly pushing the limits only running 91 octane on the 100shot.

I also have a walbro 255 and tr6 plus

Throw away the DAM TR6s they suck go to 7s non proj.

I would still retrard the time. 2 degreess for every 50 shot to be safe unless you have alot of money or another daily driver.

rollingchevys

so you think TR7 are better then a TR6 but my motor is stock beside the LS6 cam and headers to compression

Graham@NitrousOutlet

A BR7ef is unquestionable a better plug.

rollingchevys

im going to try out the TR7 what would be a good gap for 100 shot

Pull timing, don't take the 'easy' way and add higher octane.

Gap @ 34 Yell if you need anymore help.

rollingchevys

So run the TR7's and pull 2 degrees and still add race fuel...if im going to do all that im better off going with a bigger shot make it worth wild

rollingchevys

Is NOS nitrous jets the same as TNT?

You dont have to run race gas, Just tune the car on 93 octane or 94 octane. Im just telling how to do it safe. Dont be mixing gas up then trying to make it work that way. Tune the car for what gas you are going to run on spray that way your AF is consistant. Or buy a dedicated fuel cell run 109 in it then run 93 in your gas tank.

On the jets I would call Nitrous Outlet to make sure. I know I used to run a tnt kit back in the day and their jets where jetted wierd. Im sure on of the guys @ N20 outlet have a conversion chart.

rollingchevys

sounds good!! we only have 91 oct in california so i will have the car tune on 100 oct for the 150 shot

rollingchevys

i will check on those jets they are so important can mess up on that

Good for you man your doing homework before you spray.

It cracks me up when people slap a kit on a car throw some crappy TR6 plugs in which are crap then spray a big shot then wonder why they melt a piston or mess up their motor then they blame the Nitrous and not themselves. Good luck man Like I said pm me or call Nitrous Outlet and get with one of the guys.

Why? to me this is an ignorant statement. No one has ever had a problem using higher octane and I have never seen any advantage of pulling timing vs. the "easy" way.

Why spend another $100 or more if you only occasionally plan to spray especially if it is at the track.

I know nothing about actually tuning but from what I have seen and experienced I bet a stock tune can easily take a 150 shot without pulling any timing. Guys advance the timing to the hilt then pull 2-6 degrees for 100-300 shot and I would be willing to bet they are still higher then stock by a long shot. Again I am not certain on this but I would be willing to make a solid bet on this.

P.S. quotes are " " not ' '.

My truck is a perfect example. I have a custom tune(mail order) so it isn't terribly aggressive but with 110 I have ran quite a few 100 shot nitrous passes without issue. Justin said it would be just fine and it was.

Uh. Yeah. That wasn't a quote, which is why I used ' instead of ". I'm just not a fan of substituting higher octane for timing. Higher octane isn't always consistent, and I didn't know if he would be mixing pump/higher octane, which I have seen go very badly for a few people...
