In a high horsepower car is an ignition box and coil useful or can you run with out it. If you run without one what issues could you run into if any? and if you run with one what are some reasons on why it is useful? thank you

 

OEM honda ignition components (plug wires, coil, icm, cap, rotor).
Are known to handle up to around 600 whp without issues.

There after, I would recommend an m&w ignition kit with a crane coil if using an ems which doesn't allow for coil on plug.

 

it all depends on your set up and how responsive you want your car to be off the line. im running a fully built b18c1 with a 60 trim turbo and i learned the hard way by running a stock ignition set up and im well over 500hp, if your gonna have a high HP car then run a MSD 6al box with a blaster ss coil and MSD pro distributer and thats a good set up.. and make sure if you go with this set up to run all these items,if not your gonna blow igniters like crazy

 

How responsive your car to be off the line?
Please clarify... MSD ignition or an external coil is not going to make your car more responsive....

I have tuned several cars that make 500-650 whp on stock honda ignition components without issues.

 

with MSD its all about more spark, adding more spark means better response. better a/f mixture improving drivability and performance.. the stock ignition can handle a minimum of 600hp for reliability purposes from honda but sooner or later its gonna burn out like mine did when i ran 35psi mostly every weekend. thats why they came up with aftermarket products to better support high end cars with a necessity for more spark witch adds better combustion, thats were better response comes into play!! (for example, a guy can workout mostly everyday and see pretty good results but when a guy with protein shakes and and pills will most likely see better results in a faster amount time) the regular guy is the stock ignition.. and the full on protein guy is the MSD product.

 

I have a way to fix the icm problem....and other people are using a similar method making over 900whp without spending big $$$ on the t1 setup

 

I couldnt disagree more...I tell my customers MSD stands for "Mostly Sucks Dick" and I think I have seen a total of (3) setups where an MSD product improved spark function on a vehicle. Every other time I see an MSD product on a car, all it does it LIMIT the spark on the system and cause issues...costing the customer time and money.

Maybe on a domestic where ignition systems are TERRIBLE...MSD garbage works better than stock. But not on a Honda...just a plain waste of money.

 

Are you speaking for all msd ignition boxes or certain ones? The digital(specially 7 series) are quite helpuflbin higher hp cars

 

For a daily driven car the Honda Ignition system is superb. If you need a stronger spark for a high boost car, install an MSD coil and cap setup. USE OEM HONDA WIRES.

If you need more than that, a coil on plug setup is KING

 

Im speaking for all MSD products...99% of the time I see them COST my customers money, and not improve a thing.

The box may WORK...but PROVE to me it somehow IMPROVES the SPARK OUTPUT (energy)

Not saying I want you too exactly...just saying I havent ever seen a Box do anything beneficial...and no tests to say otherwise, from MSD or from a 3rd party.

...on a Honda

 

+2 on the reply above. I cringe every time a car comes into the dyno with an msd ignition system.

 

hmm. sorry to hear that. In road racing, we need as much spark and efficiency as possible. too many people on our endurance races destroy their internal ICMs after multiple events because it just can't keep up with abuses the engine being in a higher rev-range for 20-40 minutes at a time constantly. I have found that better ignition spark equates to better fuel atomization and efficiency without a sacrifice in power. Is it a power maker? God no, as it is not significant enough for "the almighty dyno" to see. But I do notice the benefits in that I don't change my plugs as often, my wires and distributor last several seasons, and there's less out-of-pocket expense of not switching out "dizzys", Especially in a turbocharged road-race application.

A good ignition system outside the OEM is NEVER a bad idea. the issue is .... which one do you choose.

 

I love my msd sci ignition...going on 10 years on the car without a hiccup. got that icm issue bullet proofed also

 

You keep dropping hints about this ICM unit you have. Why dont you just tell us about it.

 

Yup, why??
