300hp 8v NA redblock. Fantastic! Looking forward to what it gets put into.

Some people just have a gift man. this is amazing to see. As much as I love a Turbo engine, the naturally aspirated sound just gets me everytime!
Its not always about the power. Its also how the engine feels when you drive it around and sounds.
Balance, the way it rev's up etc.

ha! i visited you once in your workshop in arvika maybe 10 years ago.. back then i was like.. man.. this guy is insane! you are still! keep it up! :)

[juihmi]

Nice power 👍What kind of camshaft do you use?

[klr]

Awesome job, very cool! It looks like it can make even more power as the HP was still climbing when you stopped the dyno run? 😎

[matthewanderson]

[ericewert]

Very impressive! Are you using Alpha-N tuning or did you use a map sensor? Also is there any need for an idle air valve with the Fajs itbs?

[tejdz]

[polarborealis]

Very nice. Can you give this engine spec, what is inside of this beast?

Why not use a 16v head as a starting point?

[MBBillion]

My 2006 xc90 2.5 Turbo 5 Cylinder only makes 208 HP if I'm Lucky at the Crank 😂😔

[Tomimanty]

[JakeSkellington]

How is this possible?! What was done to the motor to make it so strong?!

[brianklamer]

How did they get 2.6 liters out of that block? Has it been bored and stroked or a typo?

[Turbotalkin]

If only my aq151c would rev that high... maybe I need a smaller prop! 😂😂

[phuneralfriends]

What’s the secret! I want to build one of these and keep in NA!

[roberttaylor]
