with a 150 shot of NOS, should i set the timing at 8 or 9 degrees??? it was set at 9, the NOS site says 8 degrees for a 150shot???!!!

 

what do you think ??

 

Every car is different, the guidelines set by NOS is just to get you into the ballpark, so to speak. The general rule is 1-2 degrees per 50 shot, but once again every car is different. My car liked 8 degrees but that was with a 175 shot. This was a 72/45 jetting combo, free flowing the solenoid essentially.

 

The best thing to do if you do not have a wide band for tuning is to read the plugs. I would try a 100-125 shot first, and see how the car responds. Nitrous obviously works great on well tuned, healthy engines- but it will also expose any weaknesses or problems with the motor very quickly. Try a 100 shot with 10 degrees and read the plugs after every pass.

 

It is important that you do this right in order to read the plugs accurately. Run the car and at the end of the pass immediately turn off the ignition and coast to the return road. You should have someone waiting to tow you back to the pits. Pull the plugs and check them. They should be slightly stained with no signs of detonation. If you have never read plugs have someone who has help you. If you fail to turn off the ignition, all of the "evidence" of your pass will be erased by the time you get to the pits and will be meaningless. You can lean out the combo by adjusting your timing up or down, (or with jetting) but after each change check the plugs. Don't change more than 1 thing (such as a colder plug and timing at the same time) either. For a 150 shot, you should probably run 1 range colder of a plug for safety. It will affect motor only performance marginally but will be safer. Start small and move up to the 150 shot after you have the smaller shot tuned!!

Gr8white, one more question, u said ''Don't change more than 1 thing (such as a colder plug and timing at the same time) either''

im gonna use colder spark plugs, one step colder, for primary ignition timing, 10 would be fine you think ????

Sorry, that was a bit vague. Changing to a colder plug actually wouldn't be a "change" since this is what you should do before you begin tuning. What I meant was, don't change jetting and timing at the same time. do 1 thing at a time so that the changes can be directly attributed to the change made and you aren't guessing about where to go with the tune.

 

Also, don't make the mistake of tuning with race gas for and then running on the street with pump gas. I've known some that liked to tune with race gas and upping the timing (for some hidden hp on the dyno and to impress everyone, whoo boy) and then go back to pump gas for running around on the street (still on the jug). You may be able to get away with short bursts on the bottle like this, but sooner or later you'll run it longer or in bad air and then boom.....

 

I sometimes would do the opposite and spash a gallon or so of 106 unleaded race gas into the tank for insurance against detonation, especially on hot, crappy air days in Texas. Safe may not be quite as powerful as lean, but on a stock block you often do not have the luxury of getting a second chance. A good, safe tune is the key to living on the street. Make sure to use unleaded race gas (if using some) when using the stock 02 sensors and electronics, leaded race gas will clog them up and affect your tune.

guys

is it worth it to port the stock heads and get a new E cam for my current combo?? will i see a change? even a small change would make me happy??

thanks

 

Get the F303 cam! You'll certainly see a change porting the E7's and adding a cam, just probably not what you are expecting and not much bang for the buck, so to speak. E7's suck, plain and simple. I think my pisser flows better than ported E7's....:shock:

I'm sorry; I was in a hurry this morning. I meant, don't get greedy at the bottom of the exhaust port and take out too much metal. There is a water jacket there. I got too close and mine cracked and spraying water into my exhaust. Witch turned into steam coming out my exhaust.
