Lightbulb Re: Mod help

Looks like a fairly sane combo.

Have you read our "recipe" area?

BTW, I have run 11.71 and never opened my motor. Some have gone faster with an unopened motor, but used huge amounts boost and a frontmount.

That combo should run 12.50s all day long and dip into the 12.20s with good air, driving and traction.

It becomes easier if you add a turbo and intercooler to that combo. With a "little" turbo like the TA49/TE44/small GT series and a stretch stock mount, the car will then be in the 11.70s consistently.

With just the turbo, I'd say 11.90s.
