Re: It's a loud boy !!

have you any silencers?

Re: It's a loud boy !!

I have one huge Martelius Exhaust silencer in the back. It has done the job nicely with the Pinto but now that the exhaust is 3" from the manifold to the muffler it seems quite loud.
Maybe it is just the long silence that has reingned in the garage.

Thanks Moggy! Now I'm strugling to find time to get the engine running propperly and need to book me a new time to get it set up. Three weeks to the first race.

Re: It's a loud boy !!

The cutting out / running issues are now sorted. The microphone in my pocket camera does no justice to the sounds.

Amazing work, well done

Re: It's a loud boy !!

Thanks Exboyracer! Seemed mighty fine. No leaks and smoke came from all the right places. And now that I've listended it for a while it does not sound all that loud. I'll try my luck with the scruteneers.
Still need to sort out the cam cover breather hose . Its a little bit in the way of the throttle linkage at the WOT position. And propably re-route the throttle cable, it seems quite reluctant to let the butterflys close. I guess the turns in the cable are too tight. Too bad I liked it there. Other than that I'm all ready for the rollers.

Re: It's a loud boy !!

A little update on this project. It has been a bit of a struggle after the last post.
We went to the rollers like we were scheduled. Had little failure in the wiring. We needed to temporarily re wire the fan and the fuel pumps to take their power directly from the battery to relieve the old wiring.
After we got the wiring done everything went fine untill the car released a huge cloud of smoke. The prop started acting up. Evidently the poropeller shaft was too short. Did not see this one coming. I've used this prop with identcal gear box in the identical position.Well almost, the box was raised about two centimeters. That seemed to be ebough. The prop was not far far enough in the gear box. The propeller shaft must have been vibrating badly alltough the roller operator mentioned nothing of that sort. Any how the the rear gasket from the box blew out and the yoke seized to the bushing in the tail of the gear box.
The good news was that the engine is running nicely and the mapping was almost done. So we re scheduled for last monday. A week before the first race.
We worked trought the weekend to get the car on the rollers again and sorted the wiring and the propeller issues.
We fired up the engine to see wheter the smoking issue was sorted. The new central electic rail/box did not warm up.
For a brief moment it seemed fine untill I noticed a worrying wining noice from the front cam belt cover. The Tensioner pulley had gone. The bearing was worn out and it had a lot of slack in it. This was a new pulley and the engine had not run more than one to two hours max! The belt tends to move away from the pulley. It was allready scrubbing against the flanges in the cranck pulley.
Evidently my lining was off or the water pump face is not solid enough for the added stress of the wilder cams and much stiffer valve springs.
Anyway I had to cancel the roller session and retire from the first race and get back to the drawing board.
I need to re think the tensioner set up. I need to loose the new style water pump and go with the older bits.

Re: It's a loud boy !!

This is how I felt for a long time with my car...........it's just development mate.......you are stretching everything to be the best......it will take time and there will be small setbacks like these.....but once it's right you will be glad you did it, I am certain!

Mine took a while and we had to try a few different things but the result was worth it.........actually every time I rally it, the sound becomes addictive and I want to do another event the day after............only problem I have is that the nice revvy Shawspeed engine is 15cm behind my head so I am always a bit deaf for a day or so after................or maybe I am just getting too old!

Stick with it............that's an order!

Re: It's a loud boy !!

Yeh I guess it is. And after all I'm GLAD I noticed the dodgy tensioner in time. So as far as the internals stay where their supposed to im not complaining.
Just a few teething problems like Jon said. And I feel confident I'm on the right track this time with the tensioner.
I'm planning an DIY airbox and a filter too.

Have no fear I simply can not give up anymore.
