Morpheus Posted January 15, 2012 Share Posted January 15, 2012 TIG Stig has to go and visit his mother-in-law today, Mrs Stig has spoken, so no welding today then. I can't get access to the workshop lathe either. Looks like the Supra play will have to wait till next weekend. Bad Mrs. Stig! Quote Link to comment Share on other sites More sharing options...
David P Posted January 16, 2012 Author Share Posted January 16, 2012 (edited) Good news is; I managed to get access to Bob's lathe today and reduced the weight of the steel water-pump idler down to the same as the alloy pulley.

I've heard about that special weight reducing paint. Quote Link to comment Share on other sites More sharing options...
David P Posted January 16, 2012 Author Share Posted January 16, 2012 (edited) Here's the back, both sides have had a good pruning and a waft of paint, it now weighs less than the PAS pulley. I am pleased with how it's turned out. Edited January 19, 2012 by David P (see edit history) Quote Link to comment Share on other sites More sharing options...
David P Posted January 21, 2012 Author Share Posted January 21, 2012 I have been let down with the TIG welding again-again. I really want to get on, so I will MIG the bracket myself tomorrow. Quote Link to comment Share on other sites More sharing options...

David P Posted January 22, 2012 Author Share Posted January 22, 2012 (edited) After yesterdays wind-up, today yesterdays job was jobbed. It was late in the daylight and with a gale blowing, so I stopped whilst I was winning and will have the test spin next session. The PAS support bearing is MIG welded, ground, tweaked, painted and fitted with Loctite on threads, splines and bearing seats. Fabricated using the standard bearing and tweaked about until the pulley rotated smoothly with no tight spots then fitted with the self centring bearing. DEFCON 3 declared. True faced OE PAS pulley Mk3 Adaptor Mk5 The finished bracket Fitted Edited January 22, 2012 by David P (see edit history) Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted January 22, 2012 Share Posted January 22, 2012 If this machine works the other thing you could consider is to modify the back alloy housing of the PAS pump to take a ball race and make a custom shaft that's supported both ends in a ball race. I hope the support you have done works, but there's a lot of flex because the support itself isn't very rigid, and it mounts to the block, while the pump itself is slightly flexibly mounted by dint of it being in its own stock cradle, (due to the flex of the stock cradle itself) cradle. If there was room I think I would have tried to mount the support back to the pump body itself, but maybe there isn't room behind the pulley? This belt drive is the one part of the setup that gives me the jitters, if the SC works well I can see you having to rethink this aspect completely. Great project, love this sort of thing, very best of luck, nice to see new things being patiently developed on a sensible budget. BTW. Thanks for reminding me about that postage, you are a gent Quote Link to comment Share on other sites More sharing options...
David P Posted January 23, 2012 Author Share Posted January 23, 2012 (edited) To get the supercharger onto a working engine, I temporarily fitted a sawn-off throttle-body . It needs a longer belt, but using the slightly smaller diameter alloy water-pump pulley, I managed to persuade the belt to go on for a maiden spin. The top idler needs minor shimming to run true and the HT lead is not long enough, but all else appears happy.

Morpheus Posted January 23, 2012 Share Posted January 23, 2012 What's it like with the cover on? Quote Link to comment Share on other sites More sharing options...
David P Posted January 23, 2012 Author Share Posted January 23, 2012 (edited) The supercharger was open at both ends for the test spin, which allowed the noises to escape. I could have assembled the suck side of things, but that would have been wasted effort, all is good with those components. It's not possible to include the charge cooler and run it until I fit the 550 injectors, AEM ECU and treat it to a day on the rollers. The test fit was to discover what belt length is required and to check pulleys for run-out. Mission accomplished and the Supra was retuned to running order before it rained or became dark.

Guigsy Posted January 23, 2012 Share Posted January 23, 2012 Bet that's going to sound mean going down the road good luck with the rest of the project mate. What's left to do? Quote Link to comment Share on other sites More sharing options...
David P Posted January 23, 2012 Author Share Posted January 23, 2012 (edited) Other than what's listed in my signature countdown. I need to order a longer belt, make a reverse function throttle ramp mechanism, order a shorter cable and tidy up a few odds & ends.

Morpheus Posted January 24, 2012 Share Posted January 24, 2012 Two Gatorback 4061030 belts are winging their way for $35 inc P&P. That's quite cheap; who from? I'll need another one for the Typhoon at some point. Quote Link to comment Share on other sites More sharing options...

You can have the redundant 4061020 if it's the one you need? Looking good David. So far so good. Planning to fit the gas-flowed runners and remove the vacuum components next, whilst at it, I can plonk the charge-cooler on and mark the spare bonnet for cutting.

I bought one 3 years ago from Summit but it's going to be too long I think. I won't know the final length until the engine is rebuilt but the bare block is still in the kitchen!

David P Posted January 29, 2012 Author Share Posted January 29, 2012 (edited) I have spliced an N/A Supra throttle cam @ 180o onto a 1UZ-FE ramp mechanism and fabricated a cable bracket. It was a fiddly job and finished too late to fit and test. This throttle ramp reversion conversion will enable me to use the shorter N/A cable and achieve smoother throttle operation.

David P Posted February 2, 2012 Author Share Posted February 2, 2012 (edited) The reversed ramp was a perfect fit, I have final fitted the cable mount bracket and the longer belts have arrived. Reversed ramp fitted It's a snug fit but easily getatable Edited February 2, 2012 by David P (see edit history) Quote Link to comment Share on other sites More sharing options...
