but if I ever get the Blower done it will be annoying.

this view of the muffler is straight down from the top , looking at the large cut-a-way section at the front of the muffler to accomodate the oil filler tube .

a view from the left hand side . a 3" donut had to be cut to make the short / sharp turn into the muffler .

this view shows how large the muffler is . It is 24" long x 7" diameter . It is 3" straight through perforated tube and fibreglass packed . many thanks go to KEVIN @ HYPERFLOW ACTIVE EXHAUST SYSTEMS for the time and effort he put into manufacturing this custom made muffler to suit the oval .

That is awesome, Really neat install, just the ticket!
I guess some quietening could be attributed to the turbo.
I will have to visit your Exhaust Expert.nn[ Edited on 31-8-2005 by OvalGlen ]

The turbo didn't quieten it as much as I had expected for such a low compression engine . I think this was due to the 3" diameter system . With the hotdog type muffler that I ran at the drags the noise was checked by the engineer 102db @ idle and 111db @ 3000rpm . With the new muffler fitted it was rechecked 93db @ idle and 97db @ 3000rpm . I still firmly believe that the majority of the noise coming from this car is the engine noise and not the exhaust noise . Runs very quiet !!

Wayne, was speaking to my Mate the other day (you probably know which one) He gave me detailed account of Your Street Registered car - drives smooth and sweet
when dawdling behind other cars in traffic and then he
described the effect of mashing the throttle -:- Basically he
said that it has spoilt his conception of a fast VW, he has been in many Bugs that he thought were Fast " he was Wrong".
He said that your car accelerates really fast and just when he expected that it would run out of puff it Keeps on accelerating. Then More and then you change gear.
He thought that it would be good in the future if you took people to the shops with you that you have
Extra Heavy duty Grab handles.
So Got the BIG :thumb:thumb:thumb:thumb:thumb
for all round use and Fastest Street Registered VW he's ever seen.

So Wayne....after quite a few months of driving this setup, is it still tractable for daily use or a bit of a bitch? Just interested....it was a question I asked earlier, but now with a few more months use, would like to know your thoughts.

I find that I can jump into the oval at any time and just turn the key and drive it . No reliability problems as yet .
I found that the cam in the engine was far too large for slow driving ( 320degree duration and .534" lift ) was suited to a normally aspirated engine and worked best with a high compression ratio .
My engine is turbo , and low compression . So I designed and ordered a turbo grind cam that would suit my application much better and would eliminate the loss of boost out the exhaust due to large overlap . The cam has arrived and will be fitted shortly after christmas . I anticipate more boost in the cylinders and more power with the ability to drive much more sedately around town .
Will keep you posted on progress after cam change .
Merry Christmas to all .....................

Hi Wayne
just a question
how well would this muffler you got made work on a bridge port 13b as my mate just put one in his RX2 and as you would guess it's freakin loud 🤪
What would it cost to get one made up
cheers

the muffler that I had manufactured quieten' down the oval from 111db to 97db , and this is straight through 3" perforated tube . Kevin also makes them to order for South Coast Rotary , who fits them to rotors to quieten them down without losing performance . They will vary in cost depending on size, diameter, lenght etc ,but the one that I had made cost around $260-00 . Give me a call on 02-42725844 during business hours and I will give you his number direct .

Hi wayne,
I sent n email the other day about some type four heads i was seeking advice on, after reading your build up on this post. Did you per chance get it, as i have had heaps of trouble recieving other peoples e-mails lately...
Cheers Graeme

well after driving the oval for just over 12 months , including back and forth to work every day of the school holidays as my son Dean wanted to cruise in it , the oval has been put back in the shop to refreshen the engine . As I didn't fit new piston rings or refreshen the engine when I did the oval build-up . I just removed the engine from my sports sedan , decompressed it , and set up the blow-through EFI intercooled turbo system . It has been extremely reliable and streetable with the only problems being 1 spark plug oiling up after many short runs around town .
I have had a new turbo grind cam manufactured , new heavy-duty camfollowers , new piston rings and I am going to up the compression ratio from 6.1 to 8.5 . I will refreshen the tied old heads again as the hybrid end-port heads that I am working on are not ready as yet .
Monday night the engine was removed from the oval . Tonight my son Dean ( now 14yrs ) stayed back at work with me and stripped the engine whilst I worked on customers cars .

Dean strips the engine for me and I am very shocked to find a large crack in the top of the engine case inside the fan housing area .
After removing the heads and barrels an inspection of the inside of the case doesn't help me as to the reason why . I cant see the crack due to its location , but I will strip the bottom end tomorrow and all will be revealed .

well, I spose the case has lived a long hard life. so it had happen at some stage.
can I get a close shot of the cuting of the rear clip please Wayne .
cheers seagull
well I have disassembled the engine and split the case to remove the crank and cam , to find that the crack that is visible on the outside of the case is extremely small on the inside . Nothing has broken in the engine and there is no internal case damage . We have come to the conclusion that the crack is a stress fracture . I will be able to have the case rewelded and braced in this area .

not so healthy , I found that the piston ring end-gaps are between 3mm and 4mm on all of the top rings . The second rings are not much better .
Also number 4 cylinder has cracked the spigot on the barrel . This answers my suspisions regarding the pistons coming too far down the barrels , when using those large 8mm decompression shims . This will need to be rectified .

the Bernie Bergmann 82mm Full-circle counterweighted crankshaft with eagle chromemoly H-beam conrods .
the crank has been flexing as the centre main bearings are very worn .
last pic tonight is the new heavy-duty camfollowers that have a .024" oiling hole in the base to lubricate the cam lobe as it is running .
