Mythbuster: continuing project thread of my 1303 '75

[wrenchnride247]

WOW! Love the sound of that motor, and the reaction of the spectators!

[dub_crazee]

the reaction of the spectators i comical! nice work again wally - everytime you post there seems to be some progression with this motor!!!

[Bruce.]

And that was without a proper airflow across the intercooler.

Nice work

Congrats Wally! 2.2 with 460HP,that´s awesome!

[Wally]

Tried to remove the diff, but after quite some work, the bl**dy tranny fork is still in the way, so no LSD this year



Will have to be done over winter time then when the engine gets out anyways to make room for the 1200T T1 project.

Great dyno numbers but too bad about the lsd. Are you going to do a full engine overhaul this winter or just pull it to get the tranny out?

Yeah, I was pretty depressed last night, but I think I'll try to lift the engine and trans by unbolting large bits of 'accessories'. If its too complicated, it will have to wait till winter.
Engine will not be opened then as there seems no need for overhaul. No smoke, no noise, no compression loss, no valve adjustments, it all seems just fine still..

I will however replace it over winter anyways with a 1200 type 1 turbo EFI I'am building as a project

[Wally]

Pulled my finger out of my.... and put some work into it and raised engine-tranny combo a bit.
That proved just enough to pull the diff out

Hi Wally

That doesn't look like much fun, I'm sure you will be pleased with the results.

I've just been offered a new Quaife for a G50 for about 1025 Euro or $1354 Au, I'm thinking that might get it.

Do you have any experience with Quaife as far a drivability is concerned?

Steve

[Wally]

No personal experience with Quaiffe, but usually when somebody says quaiffe, they mean their Torque biassing diff or TBD.
That is a whole other type of diff then a limited slip diff. Not better or worse by type, but it react different. I hesitated long, but think I prefer a LSD for my application.
I am sure you know, but I thought mentioning it anyways.

[spannermanager]

Less progression and no overrun locking with tor-sen types, they are either locked or they're not, plate types are more tunable, with different drive and overrun ramps available, but all at a price. Torsens good for drags.

[Sandeep]

Fantastic #'s Wally !

Really looking forward to your updates with the LSD installed. Judging by the pics, it looks like you'll be installing this yourself.

I'm at the cross roads as well right now ... body about to be installed but no LSD in the G50 and a 915 still sitting on the shop floor

I had quite a few email exchanges with Paul Gears and finally got some of the GT disks in my hands. They are such a difference, just feeling what their surface is with your fingers, that I would not want to ever run a original ZF diff without them.
So, either full GT diff or original and change out the disks for GT ones would be my advise.
I hope the diff measures out so I don't have to do more complicated stuff to install it properly...

[Sandeep]

I hear ya.

While that diff is out, do you happen to have the part # handy for the 100mm output flange ? I'm at odds with the local Porsche dealer and don't want to order something I cannot return.

Thanks

Sandeep

I'm very interested in how you get on with this as I have an LSD sitting on the shelf for my G50 too! Did you find any god reference material on rebuilding it and installing it with the correct tolerancing?
