I know this may be ECU forum material but I'm intested on types and gaps.

What temp rating?
What gap?

I have been told the gap has to be halved on boosted cars?

I was told to go 1 or 2 temp ranges lower and close the gaps to around 35th running my Vortech at 10psi.

NGK BPR7EF is good for 600 h.p... one colder

Thanks for the replies.

ebxr8240 - What's yours running? What does it make at the treads?

Are iridiums worth it?

On www.turbomustangs.com this question is often asked [like exhaust mods here]
The general consesus is Iridium, platnum and other expensive plugs are for long lasting NOT nessessary performance..The $2.50 NGK's are good...
Getting MSD fitted now and tuned for 55 Lp low impedance..AS the tfi module is stuffed adapting Bosch pick up and MSD digital igniter, coil...Having issues with keeping induction away from ecu wireing etc...But nothing that can't be worked out..
Should easily be around 375rwkw
BTW this means another turbo car[ebonnos] has some decent injectors from 24's up to 36 Lp..

Hmmm, you response is similar to another I read....

I don't run the Ford ignition system. Not sure if it is better or worst. It is the same style that Bommodores use.

I can get my hands on an old MSD. Do you think this will help?

Yes ..I'm letting Adam at http://justenginemanagement.com/ do it...
It has to be combatable with Haltec...
MSD or Crane have been around for some time...
