and yea i'm a little buzzed right now cuz I just got back from all I can eat crablegs and had a huge *** drink that was served to me a pitcher

Point is, buschur knows what hes doing when hes tuning evos. No one except maybe ralliart is gonna tune evos in windtunnel possibly either, people can only do what they can do with whats available. If buschur didnt have to come on here and defend himself he could be making more better parts for the evo and other cars. Leave the man alone so he can build better parts and go faster in his evo which just happens to be the fastest evo in the world as far as I know

Theory meets reality


Great video

 

No need to respond - please spare us

I remember back in the day 4 years ago tuning on Buschur's old 2wd dyno with David and Tym and there was no fan what so ever and his cars still made the most power and were the fastest - and still are

Why not spend your energy on something more useful like solving global warming ?

 

Nice test! You should drive with it in hand out the window to see if it reads close to what your speedometer reads. This would of course prove the "redneck method" of determining wind speed

 

This test would only be valid if you had second meter held by an outside party, then the other outside party an "independent" if you will, could verify your readings.

His meter would of course have to be calibrated by a national laboratory.

Now of course after the velocity of the wind had been properly verified, you would need to calculate the wind resistance of the screen infront of the intercooler, as well as the paint covering the mesh because the paints co-effcient of drag could change the CFM flowing over the intercooler.

So the next logical step would be to have a sensor behind the intercooler to verify that a proper flow rate is achieved and this also would have to be verified by an independent party.

once this was established it would become nessary to create an identical parrellel situation in order to properly test, there fore you would need another evolution with the exact same specifications on a twin dyno next to this one, and a fan that had been rated to the same specifications and this one.

That way the test could be preformed on both intercoolers at the same instant in the exact same conditions.....


OR

Just stfu and realize that the ebay intercooler will never be as good as the buschur intercooler, and if you think for a second that you have a shred of proof make sure you can back it up with YOUR DYNO, YOUR TIME, YOUR MONEY...

IN short, put up....or shut up

 

It matters because in order for his fan to displace the same air that would be displaced at a 48mph driving speed his fan would need to have a flow rating of ~8500cfm and this assumes that ALL of the air coming from the fan is directed at the face of the core, which we know is not happening.

Even if the fan could generate 50mph worth of simulated flow this would not be representative of the flow you would see on a 600+hp car that is most likely traveling much faster when core efficiency becomes an issue.

Dave, make and model of your fan please.

 

Great video, great post.

 

All of your calculations don't mean jack when you take a second to use some common sense.

He tested an ebay core, and buschur core infront of the SAME fan, same conditions, same car settings, and got poor results from the ebay core keeping the test measurements the same . Both cores saw the same airflow, and the crap ebay garbage couldn't disperse the heat. Thats the bottom line. You can't dyno tune a car and make the same power ANYWHERE with the ebay core because no one is going to have a 9 trillion cfm fan the size of their ****ing wall to make your cheapass satisfied.

All conditions held constant the ebay core got wrecked. hands down.

Getting a better fan would only increase the results in favor of the buschur core.

Also, if the ebay core could hardly keep temps reasonable for one pull, imagine how bad it would have been in a much longer pull? Buschur would have handled it fine while the ebay core would be melting from sucking so bad.

 

Coming from someone that thinks Dave is an a$$hole. I have to defend him on this one. The argument was that the fan did not put out more than 10mph airflow. Well he sure proved it puts out over 40 mph.

As for cfm well thats a whole new ball of wax. Who cares if the fan puts out 15mph and 20cfm? If the same fan was used and was placed in the same position on both IC tests the control environment was the same, or should I say as close as possible.

240z you are correct cfm is important for flow over the IC. But that is not the original argument here. If you are going to bash Buschur on this one then get your own fan and IC's and do your own testing.

Like I said I think Dave is an a$$hole and I am not a Buschur fanboy, but this time I feel he is in the right and made a fair test. Keep up the work Dave.

Jarrod: Good filming skills love the angles and how David made love to the camera.. LMAO!

I don't know how long it's going to take these people realize that you know your ****, but I got to give it to the both of you's, your both are some funny a$$ people, can't wait to met you all!

Oh and 240Z TwinTurbo: You should be on Myth Busters!!! I mean damn your pretty good defining facts! You should just make a show and see how good you can "blow David" and make his test false! Or what ever you like!

 

This post was written to disprove my statements regarding the ability of a shop fan to simulate flow over the core while driving at any significant speed.


Let me quote Busher from his original post...

He clearly states that his fans "simulate about 40mph" worth of air, not that the fan blows air at 40mph. There is a big difference and my response was the same then as it is now...


Again, make and model please

 

What strikes me as funny in this thread is that no one except 240z even understands what they're arguing about. In that original thread, I made a post stating that although I agree that his intercooler would still outperform the ebay intercooler, the on-the-road results may not be as far apart due to the additional airflow cooling the intercooler. It doesn't matter if both intercoolers were tested under the same conditions, as all that test shows is that one performs better in those exact conditions. We don't do third gear pulls staying at 40 mph the whole time.

To sum up, there is value to the original test Dave did, but it DID NOT simulate real-world driving conditions.

damn i didn't know Buschur sell Windspeed meter too. lmao. maybe he should apply to work for Home shopping network. Redneck FTMFL

 

LOL! nice work.
