My Never Ending Beetle project. (Lots of Pics)

[Wentzel]

Been a while since an update. Engine is coming along and will run soon.

Design changed and I decided to place intercooler where it was but with better bottom tank.

That's a lot of stuff to get under the lid. Does it fit, or are you going to have to reshape the stock one / go for a porsche-type whale tail?

Is the old engine going in your wife's car?

[Wentzel]

With the old engine it used to close but wanted more air to stay cool. The deck lid is open a little at the top now so I'm using the little extra space, it will close but with a small opening at the top.

The old engine is still running strong and the plan is to clean it up, paint the tins etc but probably not going into the wifes car.

So the 2.1 converted wbx is in and running. I am now busy with tuning and sorting out a few little things.

Currently the engine looks like this. Not 100% happy with exhaust sound as it is a little loud but dont have a lot of space and may change the silencer at some stage.

Some engine build photos attached.

Turn the boost

If the whole of Bronkhorstspruit doesnt know about it, then it cant be that loud

Congrats on getting it started! I am still impressed that it all fits in there!

I want to do a more detailed post from start but have a lot of pics and need to sort them and post in sequence with more info.

Tuning is going ok but slow due to time and fuel. Can't wait to turn up the boost...

Sjoe boet,.....those ponies !!!! Handful me thinks!!

Question,....changing plugs?......drop engine ?,...or are you coming in from wheel arch side ?

Next time on the road video when you get to VDO on speedo = Volksie Donner Om !

Hi with this setup I can actually change the plugs without issues. Not comfortable but possible with some funny angles haha

Hello Wentzel,

Can you provide an update on your experience with the Somender Singh cylinder head grooves?

I didn't say anything about the grooves because I can't remember all the details. But I will try to explain.

The grooves are "Somender Singh" grooves named after the person that developed it. Basically it is a cylinder head modification (Grooves) cut into the head creating turbulence in the direction of the spark plug. He claims that the knock resistance is improved and also the idle quality and driving on high load at low rpm's. The idea is that the fuel mixture is improved by the turbulence and a cleaner more complete burn results.

Tony and I discussed it when he was doing my heads and I asked him to add grooves to my heads to try it out. Unfortunately we didn't have a definite guide on size depth etc of the grooves so I asked Tony to use his discretion and give it a go. According to what I read with Turbo use you can boost a few more psi before getting into detonation.

You went for a ride in a bus with a set of simple singh grooves.
I havent done back to back testing (not many people have), but they do seem to work for my bus

Retrovan also asked me to add a set in his 1776 that I recently built. Maybe he will chime in?

Thanks Tony Z,

Just waiting to get the Hahn motor into the same spec as the Fleetline engine, to be able to do a comparison.

The Fleetline has a 1914 cc motor with out slots, and the new Hahn motor is a 1776 cc motor with slots.

To make the test more fair, I will fit 34 ICT's on it so as to be exactly the same as the Fleetline motor for the test.

So we will see in the next few weeks if they compare in power and / or performance. as both motors where installed into the same body.

will let you know.

Hi

The engine is a complete new setup so it is difficult for me to tell. The tune is still a work in progress but it does feel like it has a lot of torque down low and that might be partly because of the grooves or the new cam and bigger engine.

If I remember correctly the grooves should help for detonation too but no way to test that.
