How come every thread has to turn into a flame?

This dude made a bad *** manifold for his huge *** turbo why not give him props, not drops.......

Who's flaming???? The thing looks awsome. I just get pissed at GLHS sometimes. Which is really funny, cuz I've never meet him before. For all I know he's the cool guy to hang out with. I think the big debate is optimum length and diameter. He asked our opinions on the design and we'll tell him.

Is this a Dodge Daytona or a Dodge Caravan turbo that got dragged into this thread? Either way, Ew!

Now, as for what I said about optimum length for negation of exhaust pulse refraction backpressure- I did not state this like I knew what the hell I was talking about, I merely stated the common lengths seem to have more in common than coincidence would imply AND perhaps there is a point where the gains from negating refraction backpressure are greater than the gains from higher thermal energy!

I respect Paul Yaw's ideas and HPI design teams as well. It would be fun to calculate the speed of sound in 11.5 to 1 exhaust at whatever temperature and plot that against port timing and RPM to find out the harmonic optimum. Some one do that for me, OK :P

What makes it hard about calculating lengths for our engine's, is that they are rotaries. Like, I said before...the first design constraint is size and packaging..the next is optimum length. And yes, it was a dodge caravan turbo...how funny is that.


Think my boss would wonder why I was making something that looked like an exhaust manifold...but I should be working on brakes.

Ok....anyway....I am not a flow dynamics engineer nor do I have any collage text in front of me, In fact I am a high school drop out with almost no collage under my belt and none of that had anything to do with cad systems. However I am a CNC machinest and am quite proficient with MasterCam and some others. I also deal with quite a few parts from subcontractors for the Hanford Nuclear site in Richland Washington. I am sure you have heard of it. In fact If you were working out of this area I might have something to do with making your glove boxes.

I am not dissing on your profession at all. But I do deal with alot of draftsman and some engineers that don't know a part from a hole in the ground. They think of tolerances as nothing but one's and zero's and have no idea about the processes it takes to accually make the part they are drawing. You dont know how many times I run into something that is phisically impossible to make, and they just cannot seem to understand this.

On the other hand I would have no idea about the calculations or formulas it would take to design a glove box. I also dont have any clue about all those big words you were talking about but I have had my friend that is a Flow Dynamics Engineer at Batelle (if you work in the nuclear industry you should know who thay are) helping me out with the design of my manifold's. And I will check out paul's idea's on the subject. Like I said before I'm just looking for good information. Also since you work in the industry you should be the first to admit that not all engineers are created equal, and I think you should challenge GLHS with the same debates that you challenged me with.

I dont know why all you people have to start a bunch of **** on some website to feel better about yourself's.I guess it is probably from some childhood trama or just low self esteem.

Anyway I thank all you serious performance people for your input...I even thank all you **** talkers, cuz you have good points sometimes even though some of us dont like the way you get it out.

I sincerly apoligize for anyone that I may have rubbed the wrong way and I will not post any replys to anything that is a waste of my time.

I like my Dodge Daytona, kthxbye

Back on topic...

Very nice work man, I'm jealous. Not of the manifold, but your skill with the machine tools and welder and such. Makes me want to go take a few classes so I could produce some of my own stuff.

GLHS

I often do work for the E-boat division, working with geo-metric tolerant drawings..



92 R/T is it the DOHC turbo?

sorry off topic...

Bad2ndgen

Oh and yes I will probably be selling these once I am happy with the design. Im not sure what the cost will be yet, but if you are in a hurry to get one PM me and maybe we can work something out.

It was a dodge caravan that got dragged into this thread. You're right though, I've seem MANY engineers that only picked this profession because someone told them that they were good at math and science. These are the people that just go to work and don't have any fun. The reason I became an engineer, was because of my passion for automobiles. Going to school in Toledo gave me a foot in the door for the tier 1 suppliers (TRW, DANA..etc..etc) and some connections at Ford and GM. I love being up in the Detroit region (cept the weather) because it seems everyone has the same interests as me. Although this particular area, Livonia, seems to be Ford country. Good luck with your manifold, I'd love to see how it works out for you. Try to get some HP #'s too.
