I know some people are for and some against an aftermarket ignition. Does anybody have any real HP numbers as before and after. I want to know if they really help at all especially just with the mods I have or a stock engine. I know they really help on high HP engines and certain engines. How much do they really help as far as basically small mods? . Let me know if anybody has an answer. Thanks.

They can help send a more precisely timed ignition spark at high rpms, so that might be a little better for hp.

But for your average car they aren't going to do anything. Assuming your stock ignition is in good working order, that is.

What do you consider high RPM????

After market ignitions on a near stock car will generally smooth the idle out and make for quicker starts. The most hp you will gain is 5 hp, unless your stock ingetion is going out. You can also gap the plugs a little more. I noticed thosed with mine. Didn't notice a power gain with the box, but the coil did help me pull a little further into the rpm range, past 4,500 with my old engine.

Hey,

I currently have the coil and box. I am debating of removing the box, I mainly use my car as a show car, but do like all the performance I can get. I didn't notice and increase with box, but I was using my butt to let me know. I haven't ran it before and after, just wanted to see if anybody else had. I am definatly going to use the coil. Thanks for the info.

I have a stock 2.8 v6 \ 5spd manual > and I definitely noticed a difference. Especially now that it's summer & air is running!

Here's my experience:

Installed MSD 6al
8.8mm wires
MSD cap and blaster 2 coil

My car now is harder to start and seems to run a lot hotter than before. No performance gains But than again I have a pretty stock 305 TBI. Once there on a heavy breathing 355, I am sure they will make a big difference once dialed in.

I added a MSD 6A to a stock coil on a modded 355 and didn't notice anything 'cept for the exhaust smelling a tad better.(no cat)

i dropped in the 6al and the butt dyno shows a diffrence, a tad more torque down low, up high, the revs have more ***** and way crisper throttle responce, like some one said, noticable diffrence with the a/c on, a smoother exhaust note and the best part, hitting the 3k rev limit at 2 in the morning down a residential street with an unmuffled v8, awsome.

Well, I just took mine out the box left the coil, hard starting problem gone away and a lot smoother idle. I am going to run dyno and see the results pretty soon.

Other than making it easier to start I wouldn't think it would help all that much unless your engine was really modified. I have both the coil and the box. But I have not installed them yet.

Yea what exactly would you mean by that? Im sure that its going to give me a gain cause ill gonna be pushing up in the top 500s i hear without the spray, but i know a lot of othe people that have bone stock 305s with the box so it may not being doing anything

opps he said rpm i thought it was hp
