The Big Dawg...

Couple of noOb questions...

Checked out all of the pics on the BIG DAWG build. Was about 3,567 I think...LOL Sweet.

Obviously some coin was dropped. Why the stock manifolds? I haven't heard an answer to this one yet. I'd rather spend the one large(for headers) on something else personally. How is the monetary offset between buy headers/ceramic the stockers?

If you had to list the top 3 reasons for going with LS1 coils, what would they be?

What the heck is a crank trigger? I've heard of it, somewhere, no clue what it does.

What is the reasoning behind the turbo spacer? Relocation? Heat? Flow?

Last one... Is the coating on the intake the same as the manifolds?

The regulator on the EGR is brilliant. Looks hot too.

Are we gonna see some HP numbers!!???

:roll:

Headers haven't proven any SOLID hp gains, just problems in some cases.

If you had to list the top 3 reasons for going with LS1 coils, what would they be?


1- stock ignition sucks
2- stock ignition sucks (i would have listed this 10 times, but you asked for only 3)
3- LS1 coils are awesome

seriously, the stock ignition is horrible with big hp/big boost builds.. cap& rotor swaps often, tight plug gaps, have to have wires in PERFECT shape...
LS1 coils offer big ignition power, no disposable parts to use like a cap & rotor.

What the heck is a crank trigger? I've heard of it, somewhere, no clue what it does.

provides an rpm signal to the computer/ignition module, just as your stock HEI distributor does

What is the reasoning behind the turbo spacer? Relocation? Heat? Flow?

have to ask Nolan about this one, my guess is spacing

Last one... Is the coating on the intake the same as the manifolds?

last i heard, it was all coated with same material

:agrue:

no, the canadians never race or post any numbers.... :wink:

In Nolan's setup, he used a crank trigger to provide an RPM signal, then a newer distributor from a 4.3 that has a built in cam sensor.

eDist from FAST was used, and going to coil near plug configuration like that requires a cam sensor of some sort. There are many ways to configure it, Nolan & Tony chose this way - which is cool, cuz it's a very repeatable setup for anyone else that wants to copy it.

You'd need a distributor from a newer 4.3 (LF6 motor I believe?), the eDist, the V6 crank trigger from Mallory, which I believe Nolan drilled holes in, to change the trigger point locations, some LS1 coils, and some wiring skills :wink:

Sorry it took so long to reply to this been out of town working. Thanks Brian for answering most of the questions :wink: .

I think the only outstanding question is why the turbo spacer.
In order to run the T04S compressor cover you need to space out the turbo
or it will contact the accesory brackets. Tonys uses a 1/2" spacer and it works great. I have no A/C so decided to give my self more breathing room to ease fitting the 3.5" down pipe.

As for HP it makes when I have some numbers I will post them up.

Also after nats some time I will put up a page with details on the install and parts needed to run the LS1 coils. 8)

Right now I am just to busy working out the bugs and tunning the truck to be ready for the NATS.

If anyone is interested I have a 1/2 inch spacer for the PTE housing. $30 takes it

Hey one more...

The heat shields on the manifolds look sweet. Are those new replacements or did you fabricate those?

Somebody could make some coin pressing out some of those bad boys...

What grade steel?

The heat sheilds are stock ones that have been ceramic coated. :wink:

Mine looked pretty gross so off to the coater they went.
And it will provide more protection for my spark plug wires.
