Re: It's a loud boy !!

It's a true chimney. Big enough for the Santa to pop by
The whole exhaust pipe looks like a huge overkill in this one but if it works I don't mind. Would rather look at a smaller oval shaped taipape tough. Like I used to have.

Sorting the issues.

Some update.

Things are looking up again. As I told earlier the wiring problem is sorted as is the propeller shaft issue.
I now have an evolution 2 cam belt tensioner. Older style in the matter of fact. Which I test fitted on a project engine today. Fits nicely and I'm quite happy with the lining too. It is only a mm or so off. I hope it'll do.
I have to say Thank you for Mr. Owlcastle for providing me the back plate for the tensioner pulley. And after going trough the INA cataloque for hours I finally found a tensioner pulley I was happy with. And it even came with the right logo on it
Can't see it in the pics though.

Glad to be of help, I hope it roars!

Let's hope the tensioner pulley stays silent this time around though.

Re: Sorting the issues.

Changed the tensioner, water pump and the cam belt today. Did not realise to take pics though.
Need to check the timing again on saturday and do a little modification to the front cam belt cover.

Re: Sorting the issues.

That look to be a super solution to the cam belt tensioner... what's it off of ?

It is a Cosworth tensioner pulley. Mounted "face down" for better alignement on a bespoke back plate.
If you think of doing one you propably should get a Reyland billet pulley for Cosworth YB. I found out too late.. as usual... I had allready purchased the more expensive OE item. Not sure are the dimensions 100% identical though. So be warned.
I was told there has been some issues with the OE pulleys one can avoid with the Reyland pulley.
Or by modifying the OE unit.

And to be fair and not to take the credit, It's not my idea. I ripped it off from Mr. Owlcastle who posted pics of hes tensioner further back in this thread. He supplied me he's spare back plate.

Re: Sorting the issues.

I remember him offering the plate . My project has stalled at the moment.. so gathering info.

[Roadsport]

Re: Sorting the issues.

Yes he did. But back then I did not know I'd need it...live and learn I guess.
Why stalled?

Re: Sorting the issues.

Got some work done on the car today. Now it's basically ready again for the mapping.
I modified and fitted the timing belt tensioner today. The pulley did not fit under the front belt cover so I made a hole in the cover for the tensioner bolt head to come trough. Now the cover fits and I can easily check that the bolt has not come loose.
We've also been working on an air box for the engine.
Today I got to trial fit it and it seems to do the job. Just needs a coat of paint and an alloy plate lid. Now I finally can have the air filter in the engine. And a place for the IAT sensor.

Re: Sorting the issues.

Here are the pics. Hoping to find a carbon fiber plate to make the lid for the air box.
The wrinkle finish coating has not cured yet so could not bolt it on yet.

Keep at it you know it will be all be worth it in the end when you got a silly big grin on your face while driving it

Re: It's a loud boy !!

Thanks mate. I'll book a new mapping sesson tomorrow. Hope nothing fails this time and I do not need to cancell on the rr session. I feel confident though.

Re: It's a loud boy !!

Made some progress with the air box today. Re-did the coating. The old make shift wrinkle finish did not cure as hard as I would have liked so I cleaned it and re-sprayed with VHT wrikle finish. I was a bit nervous doing it since its oly meant to used for metals.
Also orderd a carbon fibre plate and cut out a lid for the box. Now I only need brackets for the lid and some holes for the the screws.
This needs to go on the engine this weekend. I'm booked for the rollers next tuesday.
