You know whats irritating me

We spend all our time flow testing our cylinderheads, but the intake isn't.

Getting flow ratings for mufflers is damn near voodoo.

we really need an independant flow test of other parts in the car not just cylinderheads.

 

i've seen magazine articles where they flow and compare intakes.

 

really

 

You might check with Steve B..632C2.....he actually did take a bunch of mufflers to a flowbench and tested them THEN he *ported* them to get them better!!

What die hard!!

I think I need to get crazy with it like that.

 

I have 2 things that I think would be a fun time.

I would like to open an aftermarket parts testing and evaluation center for aftermarket chevy performance parts. It would sure beat my IT equipment testing and evaluation job.

1.) I would flow bench everything including cylinderheads, headers, mufflers, intakes, carbs, throttle bodies.

2.) I would dyno test cams, do the spintron thing.

3.) Dynotest everything I could

4.) Stress test crankshafts and connecting rods

5.) Publish independant data

The other thing I would like to do, is take a pontiac GTO and make a turbo V6 motor using something like the trailblazers straight 6 or the 3.5L in the CTS, and make a Buick grand national mule/prototype. I could do dyno testing and emissions testing. That could be fun.

Primarily I am irritated by the lack of real testing of product, except glamourized advertisements.

I just have no idea how to fund such an adventure. I doubt the magazines would do it, because it would **** off advertisers, and I doubt I would get a regular flow of customers to a website to support advertisements, nor would people donate enough to regularily support such an adventure.

 

You could be the ConsumerReports.org version of speed parts, funded through subscriptions.

 

One of my other hobbies is guns. There is a magazine called Gun Test that sells no advertising and tells it like it is. They seam to be doing OK.

Go for it.

I think the space and tooling requirements would be cost prohibitive for a low volume magazine. I wouldn't mind a web-zine.

 

Guru, in fact the whole damn mess could be done in your own garage, all you need for space is a 2 car garage and a driveway....

a air pressure meter, a sound pressure 'db' meter, and a scope to read the freq of loudest sound, and then simple calculations to tell the engine rpm.....

really any shop vac is used as a suction device for say cyl head testing...open the valve a set amount, apply so much suck through a rubber mat with hole in it for cyl head to rest on the bench, and measure the amount of suck, then convert to flow rate...

On exhause, I would measure just the opposite, air pressure....

any HVAC site will substantiate about bends in air flow tubes, every 90* bend reduces airflow by some stupid unbeleivable amount...like 50% or something....so no way to account for the specific bends and how they are executed under a car...mandrel, vs bender, vs diameter,...

but, yeh....good idea....

kinda like housing inspectors for closing....guy comes out and looks the house over for mechanical/maintenance/construction defects....

problem is, they do not want to kill too many deals OR their 'free advertising' through RE agents all of a sudden disappears....
