2,4 type4 turbo 500hp -on gasoline- goal

[Wally]

Thanks! Yeah, the heads are THE best part of the engine. The twin spark makes it run so smooth too. The fact I put old rusty painted over valve covers on them tells you enough about me haha!

Even better, for initial checks I always do a test run to see if nothing leaks or interferes and it runs idle cold still really well too with the reinstalled 1000cc ID injectors
Airfilter and intake, plenum and intercooler follow later of course

Cool Wally, engine sounds sweet.
Haha cool how you got it running without the turbo connected to the inlet,
did not even no this was possible.
Shows I know nothing about turbo s.
Hope you get your goal, big thumbs up.

If you have exhaust running through it you need oil in and out of it. After that you're ok but don't be tempted to put your finger inside to stop the blades.........

[Wally]

Exactly! Oil in and out will do just fine for the turbo. Also start till you have oil pressure, only then reconnect the fuel pump relais again

Well, intake plenum and lots of other smalle things done. Dusted off the old intercooler and it installed pretty much as before. Fortunately.



Do you know the feeling where you can just sit behind the engine and can keep looking at it thinking: f*ck this is cool!

I think testdrive somewhere coming week when its dry seems possible

[Clonebug]

Awesome work Wally!!!
I love how it all .....just fits.......Lots of thought went into it to make it look good and function properly.

Did some editing for clarity.

Looks very good!

[Wally]

Thanks, that looks even (much) better indeed!

[Ol'fogasaurus]

Thanks Wally. Curious about some other things and wanted to look at them so I cropped tighter in and tried to clarify some of the other things.

This is about it for my editing program and keeping at least some of the clarity.

Always the innovator Walley, really a pleasure to see your work! One thing that I find very interesting is the expansion chambers immediately after the 1st 90* bend in the exhausts. Could you explain the theory and reason for these? Thanks for keeping us all in the loop my friend!

[Wally]

Interesting Hotel California theory Wally! Thanks for sharing and please keep those vidoes coming.

-K-

You mean this I think:

A few pages back I explained the idea about the headers Cobra: basically its an old Feuling patent I came across long time ago and wanted to realise it on an engine. Problem is to properly test it, you would have to hack it up and do it again with straight pipes... I really hate to do the latter thing.

Imo though, it should work as well boosted as N/A IF you have a comparable boost-backpressure ratio as you do N/A. I think I will realise that pretty closely with this turbo with 1,05 A/R turbine housing, so I left the N/A exhaust header system as is. Its also the plan and proces I had in mind long time ago already with the N/A 4-2-1 layout, now being 4-2-twinscroll turbine

Interesting Steve! I see that they place their anti-reversion chamber after the 4-1 location, whereas Feuling advises to place it right after the port, about as I have done. But its then 4 chambers, not one

I think (as the article also hints to) that it logically works better with large cams. Mine is 86c-ish, so thats why I wanted to try it on this engine even more.
Carbs hate large overlap at low RPM even more (as we all know), so you should see more gains on carbbed engines.

[Chip Birks]

Sounds pretty spicy!

[CobraJet]

So Wally, how much boost are you pushing in the video?
