Re: 4 Rotor Build in Sweden

Today I've used the cnc-lathe again. Fun to learn, but very time consuming.
These are for the 4-link, and fit the RERS-4 rubber protection. I made these in stainless.

Then I also turned a new mount for the rear coilovers.
Really fun to turn threads in a cnc. They always look so good.
M12x1.75 at one end, Ø12.75mm for the coilover, and then M20x1.5 in the other end.

Re: 4 Rotor Build in Sweden

Woh!! That is one serious RE Volvo build! Great job so far, I can't wait to see and hear it when it's done.

Re: 4 Rotor Build in Sweden

For you all, this isn't much, but for me, its epic...
After years in a fixture, now he is on his own wheels!

Re: 4 Rotor Build in Sweden

Loving it man! I owned a few 244's and know how stable and the chassis is and they are great cars actually. I used to frequent Turbo Bricks ; ).

Btw, are you producing 4 rotor ecentric shafts and parts for sale? Or are you only making parts for your build? I think you could create a new market for RE builders who wish they "knew a guy" that makes 4 rotor parts, or kits.

Re: 4 Rotor Build in Sweden

I only make the 4-rotor kit for myself at the moment. It would be fun to produce, but I see the 4-rotor pop up here and there, so I don't think it's an problem anymore...?

Have also bought me a set of rims that will come in handy in the future.
BBS 19x9.25" Centerlocked Magnesium.

Re: 4 Rotor Build in Sweden

Nice rim choice! Nothing but the best!

Re: 4 Rotor Build in Sweden

Nice! Super low center of gravity and placed perfect. Not to mention light as hell.

Re: 4 Rotor Build in Sweden

Bought a piece of SS2541-03 material. Ø220mm and 100mm "long".

Now I will get this to a man who will help me with wire cutting.
Will do some splines inside to fit the e-shaft. Will do with one spline loss, so it only can fit i one place. Will be better when its time for balancing.

Re: 4 Rotor Build in Sweden

It's the rear counterweight.

Re: 4 Rotor Build in Sweden

Me, my redneck brother on the picture and our dad pushed the wolvo out of the garage an up on the lift.

Re: 4 Rotor Build in Sweden

Some lack of motivation. Thought I would be going mad when the car dropped down on the floor, but thats not what happend.
Yesterday I drawed my new rims in SolidWorks. I really like to just sit there and relax and draw.
I also checked out the weight of the rims. 8.08kg/each aren't bad for 19" I think.

Attachment 15975

A little adapter as well. I want it as low as possible because the car isn't that wide. And I have long controller-arms. Maybe I will do some new wheelhubs as well :)

https://www.nopistons.com/attachment...ine=1365852958

This is the digitalized BBS's I did. All measurement are corrent and it turned out good!

Re: 4 Rotor Build in Sweden

Today I have continued on the rotors.
Did some roughing on the outer contour. Still 1.25mm left. Will be around 3.9kg when done.

Working on those rotors.
The differens of 0.01mm is the differens for GO, or NO GO :)

Re: 4 Rotor Build in Sweden

Have worked alot on these rotors this week. Totally 32 times on 4 rotors in the machine.

Re: 4 Rotor Build in Sweden

Are you going to cut a groove for the side seals, or will that center piece act as a side seal?

Re: 4 Rotor Build in Sweden

There is a sideseal-groove between the center part and the outer rotor-shell.

Re: 4 Rotor Build in Sweden

Ah, I see it now in this pic:

Re: 4 Rotor Build in Sweden

I bought a bunch of new rotors. How do I comfirm that they are 9.7:1-compression?
I have weight them, but all the newer rotors have the same weight. The 28cc in the comb-chamber are kind of tricky to check, or?

Re: 4 Rotor Build in Sweden

Keep up the good work!

Re: 4 Rotor Build in Sweden

Havn't done much lately, but have done some with the steering, the wattlink and finally some on the intermediate-plates.

This was a LEGO i designed :)

Re: 4 Rotor Build in Sweden

The build continues.
Bought standard lock rings, but couldn't let them be standard.
Grinded them from 2.5 and 3mm with friendly tolerance to 2.00mm
https://www.nopistons.com/attachment...ine=1385830236
The it was time for the grooves. Did them +0.03 to +0.05mm in height to get the right feeling. They are easy to install, and sits solid when released.

Re: 4 Rotor Build in Sweden

Bought some Ø10.0mm Chromemoly 4340-bars.
Cut them in correct lenght and cnc-turned M10x1 thread in both ends.
I use Grade 10-nuts and harderned washers to hold the engine in place.

Re: 4 Rotor Build in Sweden

Moment of truth, or point of no return for these housings...
https://www.nopistons.com/attachment...ine=1398013782

The original "oil-nozzle" must be removed before milling or else my tool, or my housing will be broken.
https://www.nopistons.com/attachment...ine=1398013782

Started with a M10-bolt and drilled a Ø4.2mm hole to allign the drill.
Threaded M5, and pulled it out with some washers and a M5-bolt.

https://www.nopistons.com/attachment...ine=1398013782
https://www.nopistons.com/attachment...ine=1398013782

Machined a Ø63mm hole for the thread, and then removed all stuff the pointed out form the housing.
https://www.nopistons.com/attachment...ine=1398013782
https://www.nopistons.com/attachment...ine=1398013782

All done. Next step is the inserts!
https://www.nopistons.com/attachment...ine=1398013782

Re: 4 Rotor Build in Sweden

Yesterday I continued with my Peripheral-inserts.
Because they are threaded into the housings there is imported to get the D-shape in the right angle to align with the pre-machined D-shape in the housings.
The D-shape closest to the housing are bigger than the round hole and the runners, so therefore I need to machine this with the inserts on the side.
I could have done a round hole in the center, and port the sleeves by hand. But I'm really not a "handyman" :) And CNC-port are in my opinion the coolest.
It worked out pretty well! I was really nervous when I mounted the first insert...
I very satisfied.
Next is to deside how to couple the inserts with the runners, and also how my runners will look like, size and lenght. Butterfly-throttles or slides.

Just because it's quiet, doesn't mean it's dead :)
My old teacher called, he had found my website, and wanted to show his friends my build in person. Really fun! Cleaned up and made some coffee.

Have been thinking about the intake, and have some ideas of how it will be.
I want thin throttlebodys with no injectors, and also buttefly model.
Something like this...

Started on a prototype of aluminium...

The P-Port-inserts will have V-band to connect the runners, but I wanted a personal touch also.
