On a race engine COP is nice since it allows you to adjust the timing for each cylinder. Also, really high HP engines need either COP or a mag in order to have enough energy to fire the coils.



Andy, isn't what you are showing actually Coil Near Plug and not Coil On Plug?

I know it's picking the pepper out of the fly poop but they aren't the same.

Got a new alternator kit mocked up in the Duster. This is a low mount 90 amp Denso alternator kit that I'm going to sell for EFI engines. I like the low mount design since it frees up some space at the top of the engine.

Working on mounting the front spoiler. I have it as high as it will go but I can move it in another 1/2 inch or so. I think that is where I'll mount it. As high and as far in as possible. Seems the safest place for it.

Sold the 345/55-15 drag radials since they were a little too big for this car and swapped on a set of 315/60-15 MT drag radials. These MT tires fit the car better. Should look mean once I get it back on the ground.

I love how the shop in which you are working on the Duster is nice and clean. It reflects in your work and we can all see that.
And your pics; how many mega-pixels are they? They are so vivid and clear.

I'm curious Andy because I ran into some alternator trouble about a year ago. 90 amps seems a bit low for all the electronic stuff you are running. IIRC this will have full lighting, heater, wipers plus all the computer stuff and the injectors.

Evidently you think 90 amps will be enough. Did you calculate all the values up? I know I had weird things happen when the system didn't have enough power. Like timing changes, fuel pump slowing down and the big one...the defroster would just start slowing down as the system ran out of power.

Maybe I had other issues.

Thanks. I try to keep the shop clean but I'm working on two cars at the same time so stuff tends to spread out on the floor and I have to keep after it. My camera is very old. It shoots 2.75 meg files. I've had it for about 15 years so it is ancient in the digital world. A friend of mine who is a photographer showed me a few tricks years back. No big deal, stuff I could show someone in 5 minutes but those tricks make a huge difference in picture quality.

I'm basing the kit on a 90A alternator which is OE fitment for a Land Cruiser. The Land Cruiser is loaded with electrical stuff such as seat heaters, mirror defrosters and stuff that muscle car guys will never have. So a 90A alternator should work for almost any muscle car.

You ever compare height between an M1 with carb to the
TF with air only throttlebody? Tb are a bit shorter right?

Thanks Andy. Just so I know...how much energy does the CNP/COP ignition use compared to the MSD 7? Is one better (use less power to get the same or more spark energy at the plug) than the other?

What I remember from all of my college classes on electricity and energy there are no free rides, in other words the more resistance to the spark plug the more current is needed in the transformer to make enough energy to force the spark across the air gap shruggy

My son's car has EFI, Coil near Plug ignition, two electric fans, two electric fuel pumps, phones, laptop, GPS and an iPad all charging.

This year on Drag Week, driving in the rain with windshield wipers and lights on, no problems with 60 amp alternator.

I would have to agree with Andy that 90 amps would be plenty for most cars. Your mileage may vary...

Correction Dad, it is a 100 amp GM unit. But it proves well capable of running all that stuff even with a 5" crank pulley and an 8 year old battery.

A Moparts member helped me out by locating a set of lower control arms that had the anti-sway bar tabs so I got those mocked up on the K frame. I've tried a couple different oil pans with limited success. I have another one on the way that should work.

Also finally got the Weld wheels for the front. I guess they had to build them since it took about 5 weeks. 17 x 6.5 with clearance for the Viper calipers and the correct backspacing.

What oil pans have you tried? the road race pan is cool but I think it's too wide for the Spool mount k frame. I like the hemi pan I just had to cut the lip off the k frame and weld it.

Viper calipers mounted on 13 inch Baer rotors. I'm using FMJ knuckles.
