Boost profile TTe780 vs oem RS6, Both on E85, the same car, same strech of road and conditions.
As you see there is not so much more lag between them.
This is 2.7L


Those are positive results, I would add *at that initial engine speed*.  I'd be interested in seeing how they compare when starting around 2300 rpm, I like what I see at that rpm.

Ok, I found some. This was while i was tuning it. Never mind overshoot. Both start roughly at 2300rpm.

RS6 starts at 2219rpm
tte780 at 2338rpm

No difference at all despite much bigger Wheels.

And these are Mafreadings from that run.

Impressive, the 780's are a nice upgrade.

Yes, I use the car as Daily and i really feel no Lag, it is smooth in Daily operations with great potential up top and gives a feel of a solid Product. I ain't afraid to push it hard.

As i stated Before. No problems with top end Power, Great figures on 2283 Wheel. Spec with some octan booster and meth. Imagine E85 than??
Problem is TQ. 820nm is a lot but it is not WOW. And the TQ ( Power under the curve) is what makes fast cars.
This is what separates tte780 from the rest.
You can hit way more TQ as low and keep it all the way. Even with similar topend Power levels it is still totaly different driving experience, Power delivery, and acceleration.
I have seen one of these 680hp RS4s on 2283 Wheel, and i Think spool is just too boring. The car doesn`t pull until way up in the register.

yeah it really doesn't happen until 4k does it. I can tell driving the imola RS4 with 2283 rs6 hybrids that's the case even though its not mapped yet. hopefully that will be getting mapped soon so if I like that then maybe.

struggling to find much on the 2280 or TTE600 sort of spec. I know Tom, Dougs friend, has them so will try get a graph this week. Tom said Doug has been cursing him for lowering the cr with gaskets as he says its made it really laggy off boost. Which I knew could be the trade off but im glad its been confirmed by first hand experience makes me feel better about not myself.

You need to lower the CR if you want less lag

wrong way round mate. lower the cr if you want to run more boost and timing for top end.

lower cr creates less response

Lowering CR is a bandaid if you have bad fuel around.  Low CR really sucks offboost and demend big turbos, for in the end it is all about cylinder filling. You are allwayes better with higher CR.
On these Engines 9.5:1 is perfect.
Specially low CR and E85 is bad bussnes.
