Don Terrill’s Speed-Talk

I use fusion 360. Couldnt afford inventor, i like it but i am still learning. It is pretty powerful for the price, even better if free. I havent used the Cam stuff. The sheet metal functions are really good. Im about to purchase turbocad basic just for the 2d drawing stuff. 360 doesnt really lend it...

Just can not afford a new truck, last new vehicle I bought was a 1977 Chevy Silverado. Vehicles are kind of like wine, they need to get a few years on them to see how good they are and what breaks down on them, so I buy low mileage used stuff. Don't know how you will use the truck, but my old dodge...

Are there Jones cams options available for the vg series nissan engines? Not many options available for naturally aspirated. Im setup for IR IDF webers at the moment. May go efi, hopefully not.

I have a heap of Bills docs and a hard copy of his porting book i can scan, if Bill is still around i can send it to him on PDF. Last i emailed him he was having problems with computers and had lost a lot of stuff. My last emails didnt go through?

I have used it a few times years ago, it is worth the money, it is really tough, make sure you get close to the finished level while it is soft, when i tried to flapper wheel out the bore on a throttle body it wouldnt easily grind down but the parent metal around it would. As mentioned the better th...

Some info here. Might be worth asking over there.

I have a set of Kieths emulsion tubes for my triple IDFs . Well made. I haven't got the engine running yet but like mentioned, if they dont work he will refund or make new ones that may work better. People are having good results on the DCOEs with them.

Racers who work-on and actually make things for what they need to support their racer are not the norm today ... almost everywhere, it seems to be, "I can probably buy whatever I want". It used to be the innovators were common racers ... those days are long past. It is a shame, really. Th...

Its the same as your spring thing, something had to make it move first, wether that is it being pulled down and let go or lifted up and dropped, at some stage it started to move, and accelerate to whatever is the max rate, before it reached its equilibrium point. Once at that point it is the same mo...

Maybe the question should be which duct will reach peak flow the fastest?

They can build up metal filings from the starter motor engagement which messes the signal up. Most diesel engines i work on now have a speed sensor on the fly wheel, but reference timing from another position sensor.

Is fuel denser than air?

Sorry double post

Harmonic oscillator. I think this makes the case that gravity does not change the energy required to accelerate up vs down. shm.gif I said i wouldnt post on this but my curiosity has over come that! What is the driving force of your oscillator? Gravity. It is then equalled in force by the spring te...
