Pokageek said:What those kits dont tell you is that the 125HP shot is not 125HP. It is more like 70-80FWHP (stick) depending on how you calculate FWHP which for stick and depending on the total HP "number" is typically calulated anywhere from XXXrwhp / .83 - .85 and for auto approx. XXXrwhp/ .80 .
Why? The reason is that you have to retard the timing to prevent detonation. Retarding the timing takes your HP level lower than you would be starting from N/A with maximized timing. For me, cats also took about 10-12 HP off the table. 400RWHP will not be achievable with your specs in my o. With a killer cam and less driveability maybe closer to 350-360rwhp best in my o unless you go bigger engine. The auto is going to hold it back also. These are just some ideas to consider.

So if I get aluminum heads and a decent cam...I wouldnt doubt from the mid to upper 300hp range. It also doesnt make sense since from what you are saying that it only makes 70-80 fwhp that in sense i would probably only make like 50 rwhp off a 125 shot since i have an automatic....Is it just me or does this logic not make any sense. Also if you use NX jets they measure the shot at the wheels and that is what I am using. NOS Measures at the Flywheel
Danman765432 said:well the thing im saying is that if i get aluminum heads, they allow you to up the timing higher then normal anyway and i know the rule of thumb of 2 degrees timing for every 50 shot of nitrous...also if you keep compression lower and dont go to high you will get better results with the nitrous...all power adders low compression including nitrous even though it can be used with high or low compression.
also what size injectors do you have on your car and what are you currently jetting? Like if you have the nos kit what is your bypass jet size and your actual nitrous jet size?
