About 2.3 20V 7A

Hi guys,

It´s real?

" according to some I have spoken to over here (worked in AUDI) there were version secretly built that took up to 230 bhp. "

[prj]

AAN is 230bhp from factory

If I understand the page author references the 7A engine. This would be true?

I have not heard of the 7A ever being tuned to 230 HP but it would not be beyond the realms of possibility , the touring car engines for example were 1.8 and 2.0 non turbo engines and made 280 /305 HP respectively .

At what revs/what fuel?

[Nuno Cristiano]

Probably just in their development that was possible.

As we are talking about a community with more in the culture I Audi I decided to open this topic to learn more.

I think rev isn´t important.

Can be normaly 200/220/250hp at 6300/6500 or 6800rpm..

Probably work with more octain, camshaft with more timing and lift.. FSE..

Revs are everything...

What are you talking about ?
These were full race spec engines and ran this power for the hole race seasons .
As Pri says they make power by revving to 9000 rpm + and having very good flow , its all about the head work and maintaining high flow at high rpm that's how you make power . F1 engines make 800 HP at 18000rpm from 2.4 litres for another example

You dropped a zero there mate

18 000rpm..

Tricked into a zero. Calm because I as well.

Revs isn´t all. It´s my opinion.

psst: you DO have the 2,3( 7a marked) OETTINGER verson NA.. 220hp i think....BUT they do have the 83,00 bore and some have a custom audi/ vw crank with 94,5 stroke...2555ccm... i have one of theese at home... with ported head an IM (1cm bigger holes)

[prj]

Power = Torque*RPM/5252.
So yes, if you want to make power, you have to have as high as possible torque at the highest possible RPM.

If you increase displacement, then obviously you will make more power, but then it is no longer a 2.3L engine.
