Demigod...The hopefull quest for more...

Thanks guys....Rome could be built 😀 faster if the builders were allowed to work 🙄

I orgenized some free time on saterday, got in the car, loaded the richer map with the voltage comp. It made one hell of a difference, the car idled sick because of the voltage compens....so I sat a bit sorting the idle....what do you know...it did not idle at over 2 ms any more....

After that was sort, I started to leave my home, was on my way to Charl to do some data logging and in one shot sommer see the Z32 the bugger got.

So I started to drive, I pretty soon saw that the richer map + the voltage compens. was heavy overfueling...did not want to boost and spitting dark clouds...so I stopped at a place and loaded the leaner map i had before and just added the voltage compensation...

All I can say is that the acceleration was scary, hesitation gone, it pulled like a demon, I can honestly say I had shivers.....then I turned on the datalogging and wanted to do a few 3rd gear pulles at different boost levels....and then.....

For one thing...the first...the computer frose up(laptop)....then I heard the sound I have heard before....the turbo hitting the engine mount on boost ( some time back the same thing happend and after investigating I found that the engine flexed so much under boost that the compression housing hit the engine mounting...so I took a piece of the mounting off) while I was busy I decided to make the mounting solid...so how it is hitting now I am still to investigate.

In anycase, it seems that this caused a leak between the turbo and manifold....it now leaks so bad that there is very little acceleration....it sounds like a tractor....

I at least now know 2 things, the voltage compensation makes one hell of a difference and that my fuel map is close to the ball park....

Could you see if its just the bolts that came loose?

Not really, just parked the car when i got home....but thats the only thing that makes sense....if the gasget just blew it could not leek as bad as it does...

My car did that once. It sounded like a tracktor them I keept on re tightning the turbo to the manifold and same shit . My problem was the studs keept comming lose so I had to tighten the studs then lock up the turbo.

Thanks...will have a look...but I think it's time I slap on the new manifold and turbo...

I asked Charl if I can have some of his time to make the wastegate pipe of the new mani because he has the tig welder on hand...but after considering that I still have to do intercooler pipes, get the exhaust at the right place and time constraints, I decided to take it to my local exhaust place, they are sommer going to remove the current turbo and mani and fit the new turbo and mani, from there manufacture all the pipes needed.

I have a 46mm wastegate that I think will be to big and don't want to waste time if it does not work, I ordered a xcell 38mm wastegate, should be here by tomorrow, my hope is to get the car dynod by friday so that i can be ready for sundays supatrax at Zwarties.... 😈

Not that I am going on the track or skidpan....

You in a hurry hey. 😀

Much 😂

sounds good Derek.
Cant imagine what it will go like with a bigger turbo.

Although I was sorta of opinion now that you didn't have the super shiniest of red SX you would attempt the skidpan. Its a ton of fun.

The old days.

😈 😈 😈 😢 😢 😢 😢 my most shyniest red beloved sx...why did I ever sell....

The progress and the new wastegate..

did you check the turbo if it was in good condition?

also yours sit so much lower than mine did its looking nice

I did, all looks ok, you did aswell when you sold it to me and said it looks good to go...

Thanks, yes it sits very low, I also thought it would sit higher...

I am sure I am still close to the ball park but with the T3 housing I might have to adjust here and there till I can get to the professionals.

Just for interest sake....the T28 also has a AR60 compressor housing...it looks the same size as the T4....

Looks good would like to see it in real live. Sunday.
