1385 supercharged engine

[samotorsport]

So it is time to build a new engine for my 67 Herbie


It was my first aircooled project , some things i wouldn’t do nowadays anymore. For example the engine lid is a 65 now , one day it is going to be all 67 again , but thats not the point right now
It needs a new engine for next year as the one installed right now is almost done.
The base is a 1200 cc industrial engine.
Going to be a big bore 1385 cc engine



Stock 64 mm crank and con rods . 83 mm Pistons

Case is already prepared for full flow



And the fuelpump place is prepared to support the supercharger bracket



The charger is going to be an AMR500 , fed by a 40 DCOE , but my idea is to only use it as a cool looking throttle body and the fuel is going to be injected by a free programable EFI .


The heads are going to be 1300 DP , they need a full rebuild , seats guides out , wekding up cracks and so on , so plenty to do






Camshaft remains stock
EFI most probably a Speeduino .
My goal is to have a oldschool looking supercharger setup



But running just like a stock modern engine .

nice, what are your plans for charge cooling? are you injecting before or after the SC?

[samotorsport]

My plan is to inject as close to the inlet valve as possible .
I plan on modifying stock inlet elbows by welding on aluminium adapters to put nozzles on them .
No cooling is planned , max boost will be 15 psi / 1 bar .
I hope to be around 90 hp and good torque , max 5000 rpm

if you don't fancy making them the injected VW manifolds are exactly as you mention but then i think you may need to look at what injectors they take?

Thats gonna be a really nice drive!

have you seen this?  https://www.shoptalkforums.com/viewtopic.php?f=3&t=151261&start=195 its a 1300 with AMR500

Yes i know about the original injected ones , they may be hard to find around here.
But i got elbows , aluminium and a welding machine .
Will see which way to go .
No i didn t know that built , but will have a closer look to it for sure .
Thanks a lot

Valve seats are out , now comes the tricky part to weld them all up

Nice.
Are you going to keep stock sizes?
