Don Terrill’s Speed-Talk

Hello, I've bought an inline oil thermostat and 19lines cooler radiator next to it for my project car. Both are Mishimoto and -10AN fittings are included. After I bought it I made a flange for the car oil system disable oil/water heat exchanger. Because it has a terrible design and it often mix oil ...

Maybe the factory is using a small amount or poor quality lube and you can add some or replace it, or add a grease fitting. That or looking at other FWD cars(or Alfa models, do they make a truck) that have similar design with stronger ball joints that can be adapted to the Alfa without too much mod...

It is almost impossible for me to do an offset flange. I have to buy new calipers new disc + I don't know what else. I've thought that before. When my 330mm Front Disc are bad for me. I'll go 356mm Disc + 6 POT Caliper + 18" Wheel all around.  It Means I have to work more to earn money :D https...

I want to add more pictures...

Hello, Me again after for a long time. Mean while escaping from Covid19 I did some progress in Suspension geometry and design. 3D Scan of Upper Arm https://i.hizliresim.com/zwigyhd.jpg 3D Scan of Lower Arm https://i.hizliresim.com/hwi42er.jpg 3D Scan of Knuckle https://i.hizliresim.com/mykjpcb.jpg 3...

http://www.colemanracing.com/Ball-Joint-Mono-Ball-Lower-Mid-Size-GM-P4392.aspx If you have access to a lathe and mill, it should not be much trouble to fabricate something. I have CNCs and Lathe, no problem. Only problem I don't trust my self about the strength of the finish job. Maybe ball joint a...

With what parts specifically are you having problems? The big and small bushings can be replaced with spherical bearings. Is there a racing or otherwise more durable ball joint available? rod end of the arm is the weakest link. 10 USD part kills the whole arm. And Arm is expensive 360USD lower arm....

The billet arms pictured certainly look "nice", but I would have significant hesitation for any hard/street use based on just my eye. Alum has a finite fatigue life magnitudes less than steel. It's a non redundant part with catastrophic outcome in failure. 7075 costs a lot more to purchas...

What are the chances of machining the OEM part to accept replaceable aftermarket ends? It is impossible to make. Because there is no material on the edge of the arms. So I have to make them billet. Or Welded from 4340 maybe ? I'm looking all my options. I'm sorry I could not wrote. I could not ente...

Forged 6061T6 aluminum will be about 10% stronger than billet 6061T6 aluminum in yield strength. Unless someone actually witnessed the forging process, I'm doubtful that it is "cold-forged." Material needs to displace during the forging process and heated material displaces and leaves a m...

Hi I'm using Alfa Romeo 159, it's relatively heavy car. Front Wheel Drive and Front has double wishbone suspension. As you can see, it is cold formed forged aluminium, and it is very tough. But bushings and rod end is pain in the ass. Every time there is a problem, we need to buy whole assembly. And...

I've finished Intercooler Installation. https://i.postimg.cc/k6t3TBT6/Whats-App-Image-2019-06-28-at-15-41-24.jpg And did some tests. IAT = Ambient +17*C Max :shock: (After 4th gear WOT from 1500rpm to 4500rpm then 5th gear WOT until 4000rpm ) Ambient was 30*C. There is lag but I don't and won't mind...

What do you think about, If I have a stock head, and only bigger plenum, How will help me ? I've bought a second hand head, And new Manifold. My Euro-4 Head ports are 1mm small in diameter than Euro-3 Engines. I've learned that They put Euro3 Manifolds on Euro4 Heads and port match only. I will give...

I think I will first buy a second hand proper head. This is necessary. And leave it stock. Maybe I can redesign my billet manifold ports to match its size and dimensions to use the plenum. Or I can go all the way back to full stock. It will be a costly education #-o For the port shape as it is, you ...

Hi, I'm having problems with my IAT, and Air Flow in my Turbo Diesel Engine. I have a GTB2060VKLR Turbo, with 10+0 Billet Compressor Wheel. Bigger Intake Manifold ( Bigger plenum, and Bigger Inlet ports+runners ). I'm getting new tune for my car. And Yesterday, My Tuner said to me that my AirFlow da...
