No. Still plagued above 40 psi. There are a few COPs with built in ignitors I have been looking into. A friend of mine is converting his evo to use yaris coils, and he brought one to work for me to test out, fitment wise. What solution did you have?l0ch0w":1djzzcvc said:were you ever able to solve your ignition breakup issues? If not I know of an inexpensive solution
I find that do be a damn good time for those tiny tiny street tires.

You'll find that 550awhp is still quite a bit o power to the ground.
You can always go bigger. I would suggest just sticking with the GT35 for now.

I could only dream of that much hp

On these cars, 500+ hasn't been hit too often, and reliability isn't exactly established just yet due to lack of long term feedback from a good amount of members.
To all four wheels, 500hp will hook to the ground pretty nicely and still be really fun. If you want to go balls out, you will need tons and tons of money for this car to get the power and drivetrain you need.
Would be nice to see you go for it!
I plan to get mine there eventually, but i'm only setting the bar to 500+ right now, then probably redo the setup on the same or different block once I get a bit more time on my hands. For now, I can at least modify everything else (like you've been reading on my thread!).

l0ch0w":1gehwcat said:Trevor, are your COPs running through some sort of CDI controller? If so which one?
l0ch0w":ke2tk9si said:I just dont know of any COP based coils that can take more than 2 or 3 ms of dwell...
Dwell time for the most part = spark power. The more dwell a coil can handle, the more power it can push out. Its entirely a function of inductance load on the primary windings to be fed to the secondary windings. At some point you reach the limits of physics... The drawbacks to coils that can handle more dwell time is that they also have cooling issues. Beyond a certain point, 8-10ms or so, it can also start to effect maximum rpm. Do you know what the dwell time is on these yaris coils I think its 3ms but im not sure? If its still only 2 or 3 ms max then I dont think its going to solve your breakup problems. I know I keep pushing them... but the lq9 coils handle up to 6ms of dwell, and are internally controlled, so even if you mess up and set the dwell to 10ms it will internally regulate to 6 and run just as cool.
Ethanol and q16 require stronger sparks to light off correctly than does standard pump gas, which means if you want to run those fuels you are going to need to be able to light them off at 9000+ RPM. Flex fuel vehicles typically have a spark plug gap of .050 or greater just for reference. What is your plug gap?
AEM and a few other companies have CDI based coil on plugs, and while CDI can run very well, if you ever plan on ever driving it on the street, you basically need to buy two of them. They are still so highly unreliable that few get more than a thousand miles out of the controller before it shits the bed. I know you want the clean look of coil on plug, but it may be inevitable that you will have to go with external coil packs...
Hopefully these yaris coils can do the trick, although I cant imagine they are much different than the 1zz COPs...
