Great info big guy! Love 12 valve stuff!

[@palmersperformance7117]

Thank you. What other things would you like to see.

3” intercooler and piping!! That made all the difference in mine, I wonder how much further that would improve yours. 12 valve science is my favourite! Thanks for the video!

[@palmersperformance7117]

Yes, probably help.

A calculator puts you at gaining 120hp. I would say you fixed some problems during this repair. Keep the 12v content coming.

[@gpalacios6850]

Great video! Do you port and build heads for others?

[@palmersperformance7117]

We do at the shop I work at.

[@adambatchelder4121]

Thats a good improvement. Did u build the headers?

[@palmersperformance7117]

No, my cousin did.

[@Ghosts_and_Cars]

Any mpg gains?

[@palmersperformance7117]

I feel that it has, but don't have any numbers to back it.
