Injectors and meth injection advice requested
Hi guys, I am hoping I can get some advice about my injectors and some guidance on my meth injection plan.
I know you typically size injectors based on your HP, but I currently have only guesses about what my car is making HP wise. Never been on a dyno or a dragstrip. Actually it's mostly been on jackstands.
It is currently carbureted, but I am switching to efi over the winter (Plus new heads, tko600, 03 cobra irs new countertops, kitchen sink, you get the picture).
I was hoping someone could look at my combo and tell me if I'm in the ballpark.
It's a somewhat high compression N/A 351w.
Here are the specs.
1984 non-roller 351 block .030 over
Ross forged flat top pistons, so should be about 11.x to 1
Eagle forged H -beam rods
195cc AFR renegades, 58cc chambers (new heads I mentioned)
retro-fit hydraulic roller small base circle cam (Comp cams)
.576/.577 240*@50/250*@50 114.0* LSA
Due to some kind of crazy balancing that has been done to this combo before it has a 0oz balance at the crank snout and 28oz at the flywheel.
I have the Mass-flo throttle body, Edelbrock Supervictor intake with 30lb injectors.
Also have the Mass-flo maf sensor calibrated for 30lb injectors.
This will be controlled by the Pro-M EMS with the COP option and fed by two parallel inline Walbro 255lph fuel pumps.
I think, perhaps optimistically that I will be somewhere around 425 at the flywheel , which I think puts me at the upper end of the duty cycle for 30lb injectors, but if I'm spraying a bunch of meth that will somewhat reduce the work load on the injectors right?
I guess this is a long winded way of asking if I'll be OK with the 30lb'ers, and is that with or without methanol.
I plan on doing the meth injection either way, and that leads to my second question.
What do you guys recommend for a methanol setup for a carb style intake? Can I get away with just drilling and tapping a cheap 1 inch aluminum carb spacer for nozzle(s) and putting that under my throttle body? What kind of pump, how many nozzles etc? I'm going to use the Pro-m ems as the controller obviously and I have a 3 and a 4 gallon RCI aluminum fuel cell for meth/water tanks, depending on which one fits better in the trunk. Everything else is undecided.
Thanks in advance for any advice you can give me.
