Thanks Dave for this informative post...many can benefit from this!

 

An 03 ringer? Interesting theory.

In any case, this thread is exactly what I need to know about parts. Actual data consisting of facts and numbers. The more I read about Buschur Racing the more impressed I am. I wonder if any of the JDM manufacturers put up their numbers so candidly. Truth be told I'd rather buy parts with test data available to the general public than some mystical overseas magic part. The only thing to make this better would be a tuner face-off. Get the east coast guys vs. the west coast guys vs. the red states on the same dyno hardware on the same day on the same gas. Break down the results by price, whatever you can get on the car for under $1000, $2000, $5000, etc..

Cheers David, fight the good fight and you'll have customers coming back again and again.

 

I think o5s make more power stock then 03s on the dynos because of the 10.8housing.

 

Yup. Less restriction in the exhaust.

 

Awesome thread. Im subscribed to it. Im real curious as to what its gonna do because I just bought there stage one kit.

 

Thanks for all this information! The cars are certainly different. Sometimes tuners/shops get a bad rep when the real problem is that the customer got a weaksauce car. Interesting stuff, please keep it up!

 

The grass always looks greener on the other side of the fence. Great job thanks for the info.Will keep watching.

From what I know - David's RS is an '04 and the variation could be easily explained with normal car to car variance

At Pruven the weakest stock evo was 208 and the strongest 267

Its a lot more interesting for me to see where the car winds up than where it started !

This will be a great journey to follow

 

Wow!! That is one heck of a difference!

 

Maybe this explains the monday and friday car theory

 

Keep in mind that is over a sample pool of prob 40 totally stock ones - over 1 1/2 year and with varying air temps, humidity and most importantly FUEL

I am still convinced - BTW - that the guy with the 267 whp - which wound up making over 280 with his Dyno Flash must have beeb running race gas - although at the time he adamently denied having anything in the pump but 94 octane

What is very interesting for me is that 95% of the post tuned stock evos make within 10 whp of each other - usually between 255 - 260 on bone stock evos with the flash. Obviously proper tuning and adjustment to match the individual car is some what of a leveling influence on the power outputs.

 

IMHO - more of this variance is due to the fuel used and also the COOLANT temps which you run while on the dyno. Evos are very sensitive to coolant temps.

Also - to a lessor degree - we have found on some of the so called "ringer" evos that the wastegate actuator arm is usually adusted a bit tighter and the cars are able to make stronger boost

Timing, a/f and boost are the building blocks which set the power levels. These are the variables which change and which are the root of the whp variance.

Great test Dave. Thanks for taking the time to perform such a test. I'm not sure if you did a similar test with the 03. If you did, it would be interesting to compare the total HP gained (with airfilter, dp, axel back, boost controller, etc.) between both cars.
