Scenario:
2004 LQ9 Auto, ECSB, Thorley headers, Magnaflow cat-back, Trans-go, Vette servo, Stock or TB converter, HP Tuners tuned on a wideband.

Which one would: Dyno the most, have the best driveability, have the best ET, have the best MPH?

1. STS Turbo system, basic kit as shipped with 5 PSI.
2. Radix kit as shipped ~6 PSI.
3. Procharger kit as shipped 8-9 PSI.


I'll go first, guessing from what I have been reading for the last several hours!


Dyno: Procharger
Driveability: STS
ET: Radix
MPH: Procharger

 

On stock converter..... straight out of the box base kits.

Dyno: ATI (If intercooled version)

Driveability: Radix (I can't say for the STS because I dont have a base kit and mine is defiantely worse than stock at part throttle due to my low timing)

ET: Radix (works the best out of the 3 kits without a converter)

MPH: Not real sure, the ATI might not build boost quick enough to get you moving and building up MPH but it's also the only one that wont fall off on the top end.

Now if we are talking with different mods then my choices would be different but as per your criteria those are mine.

I love my STS and wouldn't trade for any of the others but my kit isn't perfect for everyone out there.
