has anyone here ever devised a plan to make the dizzy a bit more reliable in the heat. heat shield, external ignitor if such thing exist. i know the easiest way is cop or dis but a bit to expensive for me. suggestions.



i know the 4age comes with a factory heat shield for the dizzy i wonder why honda never thought of that.

 

We duct air to it on our ITS car. So far it has reduced ignitor mortality by a lot.

 

this is interesting any pic's

 

Carry a second one as a spare.

I always do just in case. Nothing bites more than being miles from a parts store and a broken dizzy

 

oh i do too just wondered what the racers did which is what i obviously already do lol. i too keep a spare one but i was wondering more of a tech version of a possible fix. i do see that certain toyota 4age engines have a factory heat shieldfor there dizzy's for obvious reasons.

honda ignitors just plain suck.

 

Just carry a second one from vatozone.
If it goes out you are covered under their warranty.
Vicious circle I know, but its the simplest way to not end up paying for another should one go out.

 

ive only seen heat shields, not many tho.

 

I'll see if I can take one real quick, but it is quite simple. A 2" neoprene hose starting at the bumper and ending at the dizzy.

 

Only the best of ghetto engineering for the SPIFF Racing Teg.

 

Apparently, I need to re-read the 2012 GCR.

 

I read a great article in car craft a while ago. (too lazy to find a link) regarding distributors. It interested me because I was a an electrical engineering student. The cliff notes of the article- convert to coil on plug. This lowers the duty cycle and raises longetivity of all related ignition components by 75%. For high rpm motors that is a pretty dramatic difference. By giving each cylinder it's own coil you are essentially asking them to do a quarter of the work. (4 cyl more dramatic in larger motors). This results in less heat and better spark.

thanks for the info guys but reading owns you guys i know cop or dis is the easiest route but the most expensive route.

 

We run a Del sol here in Nova scotia Canada, we used up two igniters and 1 coil last year converted the car to a MSD distributor with extrenal igniter and coil, half the year down, burnt up some plugs but other then that no ignition problems. We only race in at best 35 degrees C. You guys deal with more heat.

 

wrap it with dei cool tape or dei gold ?

 

The Hondata Coil Pack Retrofit solves the dizzy issue by eliminating it. One year and counting.

 

ducting it and staying off the limiter helps alot. i did that in the 90° heat of west VA a few years back and it worked enough to get through a 30 min race. now i just run external coil AND ignitor. works great. the msd billet dizzy works good also. quality parts inside that bad boy.

 

pics of ducting setups (ITA rules limit me to keeping everything inside OEM dizzy

 

crap photo, but i can't find the rest. i just stuck a piece of 3" hose int he headlight and ran it straight out the back to the dizzy.
if thats not legal for IT, just run it from the lower valance like a brake duct and up to the dizzy.

 

 

There were some years of h22 that had external coil and then some old carb'd accord had external ignitor. I want to get both and mount them somewhere off to the side away from the engine with a big computer heat sink and a 12v fan.

 

There's also nothing in the rules that state you're allowed to run ducting to your dizzy, only brakes. I can't imagine any protesting you for that but if someone knows the statement in the GCR that makes this dizzy-ducting A-OK, please point me in that direction because I'd do this myself.

You could just leave your radiator fan on the whole time or if you can, find the "extreme temperature" distributor from Rich Porter Inc.

I leave my rad fan on the whole time I'm out on track and after 3 years I'm still on the same dizzy making the same power.
