prc 2.5 with magic stick dyno
but that's not the end of my story - i have unmilled cylinder heads - the machine shop was supposed to mill to 30,000ths & guess what--- he milled them to 50,000ths -which raised the compression - which screwed up the setup. i asked the machine shop to set things right - they won't =so i contacted a lawyer
-i can not wait for a settlement
- the need for speed is really burning because of the short dive time this season-so i had to start over......my new life story starts a little different - with a complete 408 long block from FFHP (
Brad is a great guy really KNOWS what he is doing!)here is the set up:
casted iron 408 block
PRC stg 3 6 liter heads (hand finished by FFHP)
Diamond pistons
TSP Texas giant cam
the car has been up and running for 2 weeks & i have 1,000 miles on it - parttime driving -
IT"S TIME TO DYNO!!!!!it is running so good that i can believe it -with a mail order tune
it is running a little rich - but running like nobodys business
i'm taking the car next friday to Wheel to Wheel for the fine tune - can wait to see my numbers now
as soon as i get back i'll share the info
What you guys think????

We can provide any correction you want. (STP/SAE or raw). Our numbers are exact as the dyno is calibrated frequently.
Again...
STP = Standard Temperature Pressure Correction. This is the standard used by the aftermarket performance industry.
SAE = Society of Automotive Enginers Correction. Used by the auto manufactures.
RAW = No correction applied. Invalid for any use other than at sea level, 32deg F and normal baro pressure.
Depending upon the day (In Lexington) STP Corrections vary from about 4 - 8 percent SAE from 3 to 6 percent.
DJ numbers seem to always be 1 to 2 percent higher. This is based upon industry write-ups, SF, our comparisons with NASA race dyno tests and information given to us from DJ. When we talked to them when were were checking on what dyno to purchase. They explained that "we would get more customers with a DJ, because it reads higher".
Pinch rollers are also much more inaccurate and several fudge factors have to be computed in the software. Tire size vs. rolling resistance etc. You often get what you pay for.
When we save our numbers from your results, we save all the data. SAE/STP, etc. So that later any comparisons can be made.
I think it is about 3% difference so subtract 3% and you will get an approx. SAE #
