TorqueHead vs Opti
 

Can a Torquehead System be used in place of an Opti - PCM In Stock?

Re: TorqueHead vs Opti
 

No. You have to run the Opti Spark. You are allowed a crank trigger. The Opti Spark works just fine.

Just spoke to Tech Director Pat Cvengros.
Cannot use crank trigger in Stock with an Opti
can in Super Stock

Re: TorqueHead vs Opti
 

The crank trigger has been allowed in Stock for the LT1 since the 1990's. I built and raced three LT1 F-Bodies. All with crank triggers. I can't remember how many times I was torn down. I never had an issue.

If you want run a stock ECU, go ahead....

Re: TorqueHead vs Opti
 

Gump is correct. Under section 8 for Stock in the rule book:

DISTRIBUTOR
Any battery-operated, stock-type ignition permitted. Crank trigger systems prohibited unless OEM distributorless ignition. Distributorless ignition must retain OEM number of coils. See General Regulations 8:3.

In this case for your LTjuan the Opti is considered distributorless and a crank trigger is permitted.

One of the issues with the TorqueHead is the multiple coils. I don't know why you would want them over a single coil, but that is beside the point. Your combo only came with a single coil (it is plenty) and that is all that is permitted.

Re: TorqueHead vs Opti
 

I will add that a GOOD aftermarket ignition box and coil is worth the investment.....

Re: TorqueHead vs Opti
 

Not really concerned about the multiple coils.
Do not understand NHRA’s reasoning but that is the rule.

It is a nice bolt on system and ECU easy to tune.
Our B-Body clubs like them.
Especially the Boosted crowd.
Agree single Coil is enough.

Until this weekend was fine using TunerCat for ODB1 PCM.
Been a 15 year labor of love learning most of the Files.
Excellent ECU. Opti is reliable.
Just discovered it’s limits.

Thanks for the help.

I use the Holley Opti replacement and I am not aware of any limits I have encountered so far. Can you elaborate?

Re: TorqueHead vs Opti
 

Dan,

With all due respect, in lieu of trying to reinvent the wheel. Listen to the guys that are running the Opti-Spark system. On the long run, it will be more reliable, better performance and cost effective.

I am !!!!!!!!!!!!!!!!!!!!!!!!!!!
Having a fight with Pat Cvengros over this RIGHT NOW !

Dan
Where did you get that information from?
I disagree since it clearly has a distributor with a single coil.

My response !!!!!
Found out mine is considered a Distributorless System
So a Crank Trigger is fine..

Previous Conversation;
No, crank trigger ignition systems are only permitted on distributorless ignition systems.
If you switched to Super Stock you could run a crank trigger with the Opti spark distributor.

Pat thinks the Opti s not a Distributorless system !
So I am confused.

Needs some help here !!
