APR Ultracharged B8 S4 3.0 TFSI vs. Gintani E85 flex fuel tuned E92 M3 DCT

[Sticky]

APR's 3.0 TFSI supercharged V6 Ultracharger system with their dual pulley setup is showing very well maxing out that last bit of performance from the factory blower. This particular B8 S4 is a catless example on 93 octane pump gas with the Ultracharger and dual pulley system.

The E92 M3 DCT belongs to BimmerBoost member @gzim335. He is running the Gintani E85 flex S65 V8 flex fuel tuning system. His car is lightened to 3385 pounds and also has your typical bolt ons. It is definitely quick as recently we saw it beat up on an ESS supercharged E93 M3.

To give some context APR recently ran 11.012 @ 122 in an Ultracharged B8 S4 on race gas. This S4 is on pump which makes a big difference.

There certainly is something to be said for the S65 V8 top end pull:

s65 = legend, that's just phenomenal response and pull on display.

People hate on it but it's a phenomenal motor.

Too bad BMW didn't do a dry dumped 4.4-4.6 liter unit with 500+ horsepower. GT3 what?

they probably could've used the parts from the M5 CSL to make a 4.5 liter track monster!

They did. They used the crank to make the 4.4 liter GTS that they never sold in the USA

Really? I thought the 5.5 s85 would convert to a 4.5 s65 like how Dinan's & RD's kits are 5.6 - 4.6 & 5.7 - 4.7

You need to subtract the two cylinders with the same stroke. It goes down to like 43XXcc.
