Alright i am in the process of buying an ign. system supporting 600hp. I have decided to go with (4) MSD 6a boxes and FC coils, with 11.5 NGKs.

1st Q- What kind of leads should i get?

2nd- What is the part # for TII coils, or can i just get some used ones?

My other q is i am planning on using BiStates injection system which allows you to inject Methanol, alcohol, or H20. I have read a few very imformative posts about the subject after doing a search but have never seen a pro/con list of each and an overall rating of each. I was thinking water/ alcohol for the street and Methanol for the track. What do you guys think( RICE, RX_Rotary, AJ, any other person with ALOT of knowledge and experience).
Thanks

 

anyone?

 

don't go w/ fc coils, get individual msd hvcii coils instead. use custom msd plug wires. just use straight water, unless it gets below freezing, and just tune for that. it's harder to tune for the different ratios of methanol, as methanol is fuel and will affect your a/f ratios.

Could you please EXPLAIN your reasoning instead of just telling me what i should do. I have gotten my ign. layout from Crispeed/ Soul Assassin setup, and simply asked what kind of leads i should use. And yes i know that methanol will affect my A/F as will alcohol. Thats not what im asking for, i was looking for a performance/ reliability comparison of the 3( from those who have experience and have used/installed them). Thanks for the response anyways.

you stated you wanted a big boy ignition system, and individual hvcii coils are the best in the business. all the drag guys use this setup, because they couldn't even light the spark w/ all the boost and fuel they were cramming into their engines. keep in mind these guys are running 50+ lbs. of boost, run methanol, and make over 250rwhp per cylinder. check out abel's and shaun's ingition systems in the links. if you want good enough ignition system, then go w/ the tii coils, but if you want a big boy ignition system, as you stated, this is the way to go. as for the wires, the msd has the lowest resistance and you can buy the unfinished v8 kit and configure it to your liking. as for the meth inj., a meth/water mix barely makes more power than water alone. it doesn't outweight the disadvantages that it's harder to tune, meth is corrosive to internal components, lines, and seals, and it can gum up if it sits for too long.

 

Thanks FDRacer. Are their any more opinions on this???

My stock FC coils with MSD 6AL's have supported way over 700 rwhp at 9 to 10k rpm with no misfire problems.
I have always made more power injecting methanol at 100% without any water. I've seen up to 60 rwhp on 93 octane with just Methanol. That's just in my experience though!
hint: Most of the smart people that I know of are actualy mixing nitro-methane in their methanol/alcohol injection kits.

 

Chris, hey whats up. Its JT. I am going to try to get down to your shop sometime this week to talk over some stuff with you about the show as well as some stuff about my car. I am planning to buy (3) 6al boxes. I also got off the phone with the company sponsoring the turbo and injection kit and they also recommended running 100% meoh. Please PM me the directions to the shop, and we'll go over whats going on. Thanks Chris

yeah, i'd definitely run straight methanol over a meth, water mix. it's harder to tune w/ a mix, cause people never get the meth to water ratios exact from fill-up to fill-up. w/ all meth, you just need to meter the amount of meth to inject for your desired afr. as for the coils, it's great if you have 'em already, but i would rather not pick up coils from a junkyard. and when it comes down to buying new oe tii coils vs. aftermarket race coils, i'd rather do the latter.

 

yea i guess it just depends, i heard today talking with one of my Mustang buddies that the C5 vette coils are bad *** so that may be another option as they are only like $38 a peice

 

Yep they work fine on a low rpm motor but when you're dealing with a high rpm/spark duration motor like a rotary it's a different story. Those coils don't even work good on high boosted/rpm v8 motors!
It's always better to use the coil recommended by the Ignition amplifier manufacturer.
When it comes to MSD's I don't recommend the blaster coils though. I've had very bad luck with those coils cracking and cross firing. The newer HVC coils seemed to be better designed although I've not actualy tested any.

 

Isn't the whole idea with water injection to reduce detonation?
How does methanol reduce detonation?
