I Can Feel the Tension!

Posted by superchargedcamira on October 28, 2007

On Saturday, Craig and his old man spent the better half of 12 hours creating the supercharger tensioner. It looks like an ingenious little design. As seen in the pictures below, it has a plate that slides up and down with two securing bolts and a perpendicular securing bolt. We have realised we need to get a tighter fitting belt though. Im sure Craig will add more information re the makings of the tensioner in due course..

Today (Sunday) we spent most of the day with the Camira over the pit. I hadnt really used the pit since id dug it out many months ago. We wanted to secure a few exhaust rubber mounts that were annoying to get to and also check for anything loose suspension and mounting wise. We did find a few things that were loose and driveability has somewhat improved but there are still some interesting knocking noises that can be heard sometimes under certain conditions – namely coming off acceleration, and some undulated corners. This doesnt affect driveability hugely however it would be nice if the car was a bit smoother on the road. Perhaps we will take it to Mikey (my local mechanic friend) and get him to point us in the right direction.

Just a quick update..

Posted by superchargedcamira on October 12, 2007

Despite the lack of updates to the blog over the last month and a half, things have actually been happening. The cars running fine since the rebuild, we spent a day going over everything, doing some runs and monitoring the ECU to make sure all was well.

The supercharger mount has now been welded to the bracket we attached to the chassis. We got the SC pulley aligned as close as we could to the crank pulley and proceeded to weld the base backet into place.

The car has been completely put back together now, front bumper and lights etc. We ended up having to cut a section out of the bottom of the front bumper as it was hitting the intercooler.

The most important thing we have done since the last post, is aquire the one way and PCV valves for the vacuum hoses. For those who dont know, these valves are used to stop positive pressure from passing through the vacuum hoses, for example a cars brake booster uses manifold vacuum, however its not designed to handle positive pressure such as is generated by a supercharger. For the brake booster we used a one-way valve from a GT4 Celica that was kindly donated to us by Tony Flood. We picked up another valve from a wreckers and a PCV valve (same sort of thing, but for crank case ventilation) from a local car parts store. The camiras crank case ventilation hoses are quite large (19mm diameter) so we had to get some converters to make it fit. The other one-way valve we got from the wreckers is for the hose between the throttle body and the charcoal canister. The charcoal canister is used by the car to absorb and store the gases that build up in the fuel tank. When the car is running, the vacuum generated in the manifold sucks the stored gases out of the charcoal canister and into the inlet manifold via the throttle body. The same thing happens with the crank case ventilation hoses, any gas build up in the crank case is sucked into the inlet manifold and combusted.

The next step is to build a bracket for the supercharger belt pulley tensioner to mount on and also finalise the intercooler piping now that the SC has a fixed mounting point. 

Thats it for now, until next time.
