I'm guessing this is an easy one for most in this area but I've been out of school for too long to remember how to do this correctly so I'm looking for some help. I have a donut shaped part with a high tolerance hole in it in 380 aluminum. The part is about 5" OD and the ID is 1.5". Using...
I disagree that weight reduction is not an issue. Pullers are always trying to reduce weight of the engine, frame and other places in order to put the weight where they need it to hook better. We used to build a lot of pulling engines at a shop that I used to work at, we even built billet AL...
Centifical/inertia dyno's are the same thing, that's just what they were called where I worked. Interesting, me and Ron have the same last name, the storie that I've been told is that there were 5 brothers that came over from Germany together and 1 of them got lost in New York (the rest ended...
Back in the day when I used to be an engine builder we used a water break dyno by DTS for our circle track programs (from my experience this is what most engine shops have and all nascar shops do have a dyno that build engines). The centrifical dynos as you are talking about we used on our...
I actually figured it out with some help from our tooling supplier. For my application (M2 X .4) the standard pitch is a D3, so I ordered a D5 and a D7 pitch tolerance taps and sent them off to the plater.

The holes need to be plated for conductivity. Thanks though. It helps to have others look at it that have not been working on it before. Keep the ideas coming.

I produce a part that has a tapped hole and is then plated as the last op. I thought I might be able to get by with using a standard tap since it is a small hole but we are getting plating build up in the hole and the threads are coming in undersized. Does anyone out there have a contact that...
Marquis is heading in the direction I was looking for (too many engineering classes and not enough english make it difficult for me to communicate my ideas). I understand stand that the CFM is advertised but I also verified it with my flow bench. Since the numbers are correct is there a way to...
Thanks for the replys so far. Dragula, I have the formulas set up in an excel spread sheet for HP and Torque using the CSA as you have stated. My thought was that using the minimum CSA would give me max potential numbers. You may not always be able to achieve this depending on the design of...
In the past when building an engine I have always had the cubes determined by sanctions such as IHRA, NHRA, NTPA, etc. For this engine cubes are unlimited and are being restricted by the heads that I have (I don't want to spend the money for bigger heads since I have these around). I want to...
I am building a motor starting with the heads. I have a set of Brodix BB2-plus heads and would like to run 540 cubes or more. Brodix says that these heads are good up to 522 cubes if ported and flow about 370 CFM @ 28". The BB3 heads flow the same but have a larger intake runner volume so...
rust bullet is the same as POR-15 but has 1 advantage that it does not break down under UV light like POR-15. I was wondering if anyone had used either and if they had seccess with it.
Michael
Does anyone have any experience with these products and good/bad opinions on either. I have a couple rust bubbles starting to form that I wanted to sand down and treat before winter on the car. Any suggestions or opinions would be helpful. Thank You.
Michael
This topic is an all day discussion, there are just so many variables here. Here are a couple things I watch for when flowing heads, one thing is to listen for turbulence and eliminate that, another thing to try is to make a clear extension tube for your bench and use some colored liquid and...
no 200 is not too low for the temp. It's going to be running at whatever your engine water temp is set for (or close to it). I would give a better explanation but I'm not fully awake yet. Are you having problems with water in the oil? Is there something wrong that you feel the need to change...
