for many years I have not quite understood what they have in the water in Scandinavia. and I still don't.

amazing what comes out of these regions for over a couple of decades now. I love the attitude, I love the craftsmanship, I love the innovation, but I can not wrap my head around it.  Shocked

please explain:

these 1600 challenge engines with std valves (35.5x32) can give a little hp if you think about it a few times
JPM s gives around 178hp
JP s gives around 172hp (available on FB)
  With 40 valve
so you can watch this movie

Flow, light weight parts and healthy camshaft.

The first on is on pump fuel as well   Wink

Really amazing what these guys can pull out of these stock valve size heads. Truly shows there craftsmanship!
I've seen some pictures of the headwork, absolutely mindblowing!
My question is, how reliable are they on the street? Or are they purely for racing purpose with a narrow powerband and in need for specific short gear ratios?

It's racing
Cr is around 14.5-15
Flow is important (but it always is) about 160-170 cfm @ 25 "
The gearbox is not suitable for the street if you do not want high revs
One of the most important things on the strip is heavy flywheels with a heavy pulley if you want a good 60 foot
Just for info, the Brazilian has driven 5.88 with turbo engine (around 500hp) with standard 35.5x32
When you compete, it is only 1/8

As Micke noted, these are race engines. Period. If you start on a clean sheet of paper and want to build a high power stock valved 1600 engine that will be functional on the street, - and by that I mean that it should work as a commuter, on the Motorway and a grocery getter (Normally aspirated) there is a limit to everything. Peak power is not the problem. The challenge is to make a set up that has enough usable torque in the lower rpms to be easy to drive and at the same time roar at higher rpm. What is a good street engine (?) That is an individual definition, but my definition is: Easy to start, usable power from 1200 rpm in 3rd gear and a general power window of at least 3000 rpm.
With the things we know today I would say that the power range for a Super street" 1600 is around 135 hp with peak around 62-6300 and peak torque of approx 160 Nm around 4700 rpm. I would build a long tube 4-2-1 header with a custom chambered muffler for it to get the widest possible torque band.
Would it be financially feasable over a larger displacement (?) No, but its possible.

Speaking of 1600cc engines , I was wondering if anyone has heard from Johan Dryselius lately? He started the World 1600cc Challenge forum and it seems that itís pretty much dead . He hasnít posted or replied to any posts in awhile.      Thanks    Tom

I would think that no one writes anything as nothing happens
And people just read because it's dead
Here in Sweden, a lot of things happen at the 1600 challenge
a car was in the dyno a few weeks ago 510 hp
But you may not want to leave info what it is in it
EFI Ft 550
