how much hp will the honda ignition take before it starts to break up?

 

600?

hondas have very good ignition systems...

 

around 400whp

 

i thinks its more than 400, there are pro drag cars with stock ignition systems...

 

cause im shotting for 500whp on my new motor in like 2 weeks and i want to know if the stock ignition is up to par

 

When I got up around 20 lbs of boost it started missing. I tried the MSD cap/CDI/coil combo, which worked if I kept the plugs gapped close, like .020 . Now I have COP, no misses at 20+ PSI with a .040 gap.

COP?

 

coil on plug

 

COP Coil On PLug ignition system...

 

Oh yeah. Didn't think of that. haha.

 

I have made 600+ on stock ignition including wires. Plugs gapped at .25

is that .25mm? or .025"?

How do you know if the stock coil is not enough already? do you get detonations? or it just misfires? Thanks!!!

 

misfires, mine weren't very noticeable, but they showed up on the dyno chart and affected performance

 

so all you really notice are misfires? Anything else

 

Just misfires, and I didn't even notice them, but they showed up on the dyno. There's some other less quantifiable stuff too, like the possibility of adding more fuel earlier with a stronger spark and a bigger gap, but I'd have to set up a controlled test for that and dyno tuning time ain't cheap.

 

sorry i meant .025 and yes you will start noticing misfires on the dyno graph before you will feel them. That will be the point at which you will actually make power with an aftermarket ignition system.

 

Prelude ignition systems are a bit finickier than the B series. Typically around 330-400 they may start to break up a little bit.

Prelude's also have a lower msbc than the B series do which also does not help.
