Dyno Session


Dyno session now done and what a session it was! My first time in the dyno and got lots of info and experience how the work is done. And of course got the report for the engine set up and performance.

But let´s go step by step and it was pretty interesting start…

First we needed to do some modifications for the exhaust headpipes:


Of course these will be welded back together after the session.

Ready for the take off:

Ready Ready2

But the spark was lost…


Reason found after checking the distributor wiring.

Then it was time for the first start:


There was some weird noise coming from the valve covers… seemed that the rocker arms were touching a bit to the valve covers:

Some_noise1 Some_noise2

and we needed some modifications and make some room for the rockers…


Then it was better:


After this, warm up pull and then the oil change:


and filter check up…

Filter check1 Filter check2 Filter check3

yes, it´s clean:

Filter check4

some additives (zddp) and new oil for the first pull:

We did the first pull but lambda curves are weird… something was wrong. Needed to check the fuel levels in carb bowls…


and needed to figure out what is causing the carbs floating? Probably the jets:

Probably_jets Probably_jets2 Probably_jets3
Probably_jets4 Probably_jets5

The jet plates were fixed and in the end everything is fine… no extra noise, shaking, floating or what so ever. Time for the serious pull:


And what a pull it was! 409 Horse Power and 628 NM torque with the cast iron manifolds:

410a 410b

Of course we needed to test with the headers as well and the result was naturally even better… 440 HP and 673 NM torque:


440a 440b

What can I say… very pleased with the results and many many thanks to Jykä and Sämpy for the excellent work!

Go Down On the Pedal and You´re Ready to Roll…

Some theme music for tomorrow´s dyno session… Remember this movie "Streets of Fire" from 1984. Lyrics for this song are pretty good for hobby cars and cruising…


Let´s Roll #5

Let´s Roll #3 and Some Theme Music…

Almost done with the right hand side sheet metal work…

Here´s also some good old music from the Finnish rock ´n´roll band called simply "The Rock ´N´Roll Band" back in 1974. Song is "I´m Gonna Roll" and in guitar there is Dave Lindholm and Janne Ödner, vocals and bass Pave Maijanen and drums Affe Forsman. This group was together only less than a year or so.
