Nitrous. Biggest shot for a 318

That system works well also, and I concur about not running too rich either. That is where I had problems, when I started. I thought I was running lean and hurting parts, when I was actually too rich. I use the "robietherobot" site to get my hp numbers. I didn't suggest jet sizes, as I have a fogger system.
We got rained out last night, so will see what next Tue brings.

PS: I now have 28 n jets, 27 f jets, Fuel pressure is 6.0, starting nitrous pressure is 950-1,000 and drops to about 900 at the end of the run. Timing is fixed at 17 degrees. Car weighs 3250

Sounds cool, have fun when the rain lets up.

Fogger is a whole different jet package as you know. They are "fun"!!! I had a car with two plates and a fogger with three manual activation buttons...talk about fun to work all that stuff and still drive. That was back when we didn't really know much about how to cure issues, we just threw more fuel at it, up the fuel pressure. :)

I agree, the old, "rich is safe" thing is a dangerous slippery slope to step on to. It lets the engine run and beat the snot out of parts. If running rich is bad when NA, it sure isn't good when running juice. I've had discussions with one particular nitrous guy and he always suggest running a f jet 10, yes 10 sizes, smaller than the N jet to start on a plate system. I've seen plate kits with a 200-250 kit end up with F jet 14-16 smaller than the N jet, where the instructions say to run equal or ~6 smaller. That's a big swing to get it in range.

Usually when I see plug straps are burning off, it's most likely too much timing/detonation. Feeding more fuel to it may mask the issue, but, that puts the engine into the rich, detonation, ring land killer territory. I'd rather pull a ton of timing and be safe, sneaking up on the right timing setting, than the opposite.

Lots of ways to tune the stuff, hopefully everyone gets to the right spot.
