TorqueHead vs Opti - Page 2

Follow up EMAIL from Pat !!

Dan,

Unless you have documentation from Chevrolet stating it is a distributorless system it’s not; so a crank trigger would not be legal.

1. Distributor: a device in a gasoline engine for passing electric current to each spark plug in turn.
Pretty clear to me you don’t have a distributorless system.

========================
SO I am confused

Just sent Pat KRATLIF's response.
Pat's response is below.

Dan
Thanks for the heads up, we will have to look this weekend at Pomona.
As I mentioned previously, unless you have documentation from Chevrolet stating it is a distributorless system it is not.

Pat Cvengros Pacific Division Technical Director (626) 250-2295

Then sent GUMPS response...

Pat Responded
You can believe who ever you want,
I’ve answered your question based on how NHRA officials interpret the rulebook.

Crank triggers are not a legal option for the Opti Spark.

So what you are saying is that you just rocked a boat that was on calm seas....

If enforced under this interpretation, this would park pretty much every LT car running Stock Eliminator! I'm pretty sure that Holley doesn't have a harness. I don't know about the other systems.

Keep being AWSOME Dan!!

Hard to put the worms back in the can after it's opened. Good going Dan !

Not even close Dan. all you have done is start a conversation that doesn't need to be had.
Where does the OEM optispark pick up it's signal? From the crankshaft? Then it's a "crank trigger" system.
IMHO, (and I'll probably catch some heat for this) any OEM ignition system that uses a crank sensor and a cam sensor to sort out the timing events should be able to use an aftermarket type crank trigger system.

A crank trigger is nothing more than a crank sensor, the LT1 came factory with a crank sensor and nowhere in the rulebook says you cant use aftermarket sensors.

Billy and DDP;
Then you better have that conversation with Pat Cvengros!
What we say does not count if he believes otherwise.

These are not our rules !
Pat is the arbiter not us !
Read the exchange….

I ran into the limits of the OBD1 PCM.
Sought advice from people more experienced than I.
The 8.3 rule was confusing comparing available products out there.
So contacted a Technical Director.

The feedback from CR is in conflict with what Pat said.
So before proceeding over the rulings cliff.
I want clarification !
Wouldn’t you?

Billy Nees · 11-11-2021, 11:54 AM

Dan, the LT-1s that I am dealing with use a Holley PCU wired into the opti-spark! How can that be illegal?

GUMP · 11-11-2021, 11:59 AM

Maybe you should point out to Pat that the later LT motors had a crank sensor?

You are not a very popular guy right now. Maybe it's time for you to fix this?

A simple google search will reward you with a photo of the later timing cover that clearly has a boss for the crank sensor....
