4. after really thinking about this, i'm coming to the conclusion that a) this is much more work and expense than you think it is, and b) the results are going to be worse than you think they are.

1. yes
2. me
3. Not using the RB Holley carb anymore. The Nikki can be boost prepped and can flow enough to make over 200hp+
4. a) no it isn't. I have a spreadsheet, and already have 75% of the required parts b) the results are going to be better than you think they are.

Now go away rotorless Haltech Troll

1. okay, intercooler is good. details of the intercooler setup?
2. how much boost do you plan on running?
3. are you going to do any boost activated timing retard?
4. i have a lot of spreadsheets.

1. No details. Core likely smaller in size than Paul's.
2. 6-8
3. No. The timing will be locked in the dizzy. 15 leading 10 trailing
4. So do I.

1. i wouldn't go any smaller than paul's IC.
2. 6-8 psi sounds good
3. can you clarify leading 15 trailing 10? you need at least a 10* split for boost.

15 leading 10 degrees trailing (locked dizzy, no advance) is what I have been told by 5 different people running boosted 12a's. I am still looking into it.

The trailing isn't really doing much with my Direct Fire set up.

I should have kept my massive FMIC. Oh well, they're cheap.

look into it a lot. if it's only a 5 degree split (that's what it looks like from your post) that may be enough split for 6-8psi, but that's pushing it, especially if you have very coarse fuel control. the trailing plugs need to fire ~10* behind the leadings.

what exactly do you mean your trailing ignition isn't doing much with your direct fire? it needs to be doing a lot. trailing ignition is very important. you have to ignite the other end of the long rotary combustion chamber, and it needs to happen at a specific time --~10-12* after the leadings fire. feel free to bring up any valid arguments for this.

i'm not trying to be a smartass here. i'm only posing these questions to help you, so do a lot of research and post a good reply
