I've read big turbo, tubular exhaust manifold (header) and NOS.

Yes, this is it.

Anything else? Pistons, rods, crankshaft, camshafts...

Try checking zatzy.com. Many of the Swedish/Norwegian top dogs hang out there. Most of the discussion is in Swedish. For engine photos you could browse through the "Projekt" (=projects) section on zatzy's forum.

Some remarks, the head flow about the same as 034motorsport ? , 2x044 fuel pumps, nos is small shot, for lag, the gearbox, has a long ratio it reaches, over 250kmh in fourth gear , i have emailed to Snarskogen about prices, i can send it to you if you want . After all the reading bottom lines, is that he does not uses ultra expensive stuff, like titanium conrods and so on, but still gets over 1000hp HOW? 034motorsport, with higher budgets did not get over 800 American Horses?

OT: There are several more with much higher dyno outputs than 034.... Here are some of them:

Åhlman: 965hp (at wheels) (Also from Sweden)

Kai Bakken: 1033hp (From Norway)

Jonus: 1065hp in the Green 90Q and 1255hp in the S2. (1255 with Nos and 1008 without)

I dont know Åhlmans budget but I think Kai Bakkens are quite high. Jonus is in the same budget range as Eklund, no fancy titanium parts or similar.

Because there is a difference in tuning methods, US cars in general seem to focus on high revving stuff.

I've found a lot of them haters for anything that doesn't rev to 8-9k and they hate stroker conversions.

The big power I5 in Europe are generally ( I say generally ) 2.5 Strokers.

Forgot Zatzy is an amazing site, the do have an english section http://www.zatzy.com/zatzy-com-international-section/

[vcosmin]

zatzy.com is great, but english section is low in informationa a better alternative is the translated google version
http://translate.google.com/translat...-8&sl=sv&tl=en

not 100% accurate, but i last i can understand 50%

[Jamo]

Cheers never know google could translate swedish, bookmarked!

[repo]

when you combine the methods, you get 1k hp with 2.2l w/o nos, like paavola did. Without titanium rods or liquid gold as fuel.

What we need to remember is that dyno figures are not fully comparable between each other, when not done on same dyno.

Maybe anyone know what is the weight of Jens Audi? Yesterday I close looked to his S4 and it looks great. Car is finished even in the smallest detail. Engine, interior, body - everything is magnific.
