Smile How much Nitrous??

OK I am sure I will get a ton of crap for asking this but here goes.

I have a 99 Camaro with a heads and a tqr 3 cam and Ls6 intake.
I have all other supporting mods to the car.

The question is how much nitrous should I use on the car. I am going to get the car tuned at Diablo Sport next week and am not sure what size shot to run. I was thinking 100,125, 150.

Please let me know what you would run and why. I am not going to use the nitrous to much. Maybe a few times a year. Due to not having the rear yet. But even after I do install the rear, I willl not be running it to often and only at the track.

150...spray away. Is the car already tuned or are you getting it tuned for that cam? If its already been tuned you just need to verify your A/F and make sure your pulling enough timing since im sure it will be advanced...do you have an external device for timing or are you pulling throught the pcm?

The car has been tuned for the cam. I was going to get it checked out after the nitrous.

I dont know what the timeing is at not but i pulled out 2deg for the 100 shot.

How much should i pull for the 150?

And how do i find out how much timing i currently have?

I have a diable sprt tuner.

start with 20 for the 150 get the a/f close to 12.5 then put a degree in at a time to find the sweat spot. adjusting fuel back to 12.7 or so. but you are going to need some 7's or 8's and check them out as you go.

You need to get a scan tool on it to verify what the timing is set at. You might be able to verify with the predator, I would shoot Diablo Sport an email and verify.

The 150hp shot should be fine. When you get the car tuned shoot for 11.8 on the AFR. Anyhting over 12.0 can be pushing it.
