20#’s out of a ported blower holy! What was the timing?

Insanity, yes I know lol!
I'm not sure what my tuner left it at for peak timing but he did say he needed to keep the tune conservative due to the boost level and also highly suggested I run the ethanol tune over the pump gas tune.
I used the upper pulley that was already on the car when I bought it, and apparently I measured it incorrectly before taking the car two hours away to be tuned. What I thought was a 2.93 upper may actually be a 2.7 or 2.8 to be making that sort of boost with a 6# lower.

Whos port/stage: Steigmeier Stage 5

The stock injectors are holding me back a little but honestly it runs great and this is plenty of power so no plans yet to put in bigger injectors and retune.

Very cool thread!

The highest I made on 93 was 530rwhp and 520rwtq in 70 degree weather in Florida.

Stiegemier stage 5, 2.76 upper, 4lbs lower, JLT RAI, Dragon tb and plenum (both ported), JLT filter, Metco idlers, supercar pumps, dual FPDMs, 60lbs injectors, off road X, Bassani catback, and gator back belt.

Now that twin-screws (VMP, Whipple, Kenne Bell) and turbo setups are commonplace, I wonder what percentage of modded Terminator still have a ported Eaton.

I have a decent build with a maxed 2.3 TVS, built engine and all the goodies well into the 700 range but still was something special about a ported Eaton way over spun. This is way faster but the low end Eaton torque and unfortunately subsequent drop off made it feel like it had crazy power.

Who’s a good tuner to go to for ported Eaton setups?

Any good tuner experienced with Mustangs should provide a good tune for a ported Eaton setup. If you were in the northeast I'd have an excellent recommendation for you.

Who would you recommend Bob? Years ago I had Lund tune my last Cobra but he’s more into Coyotes now it seems. Currently waiting on a start up tune from Second Street Speed in Perkasie which a follow cobra owner recommended.
