Ignition Module
 

One a V-8 how much advance will you actually get from one of the V-6 modules? A full 14 degrees or is it even less than that?

Anyone have a Thunderbolt IV V8-HP module?

Thanks

A V-6 module will give you about 8-10 degrees.

I have my blower motor set at 30 total and at idle I am around 20-22

Trouble Maker - I have the Thunderbolt IV V8-24 module that I will let go cheap. It is a 24 deg advance module. The timing on this module is 20 at 3000rpm which is the same as the v8-hp module. Set you initial timing at 10 deg and you are at 34 deg max at 3750rpm.

Thanks Biggus..

Powerguy...I've already got a V8-24 and a V8-22A... both give too much advance from where I need to set my initial advance.

I'm running mods that are maked "HP" . These , I believe , are for the older 420 hp models and give about 16* advance. The advance curve also doesn't start till 1400/1500 rpm and full advance at 3000. MY 540s have 35* total. These could be what you after;)

I was wondering if you would be interested in getting rid of the V8-22A module?

Sorry, sold it a couple monthes ago....

Re: Ignition Module
 

I switched ignition out to full MSD and now I can dial it in just where I want it. It's pricey but Bob T. said that's the thing to do in the Aug. issue of Powerboat in his question/ answer section.

Re: Ignition Module
 

I like to listen to everything Bob T. says, cause he is a very smart and experienced man, but I don't really think that he is always totally objective. He SELLS MSD so nothing else is any good in his opinion. There are a lot of guys out there winning races with T-Bolt IV's and another whole lot having problems with their MSD's !! --- JP

I have picked up a V8-24 and two V8-HP (20* advance) off of ebay for around $50-75. Sorry, none of mine for sell.

Re: Ignition Module
 

I will have to look in the morning but I am pretty sure that I have a V8-20R module that I took off my 1990 502MAG. I will let you know for sure tomorrow. I would be willing to let that go.

10 degrees

Any ingition can go south on you but it makes me a little nervous with a rotor that is held on with loctite ask "Carney". I carry a spare cap and rotor on board and don't want to wait 2 hours for the loctite to set up

Re: Ignition Module
 

Do you still have the V8-20 module? I am interested PM me a price.
Thanks

Re: Ignition Module
 

Dennis Moore's book has a nice list of timing tables for the different V6 and V8 modules. I'll look it up tonight and reply to answer your question. The V6 has more timing advance than the V8's if I remember correctly. The MSD boxes look great and do cool things, but they are unreliable. Take any 10 users that have them, and you will have several that have failed.

Re: Ignition Module
 

That would actually be LESS advance. 14 deg. on a V6, but more like 10 deg. when used on a V8. (I know; Dennis says it's 6 to 10 deg. but in practice I've found it to be closer to 10) Lets you run a higher initial setting for better idle with wild cam blower motors having less compression. --- JP
