I didn't add anything. The beauty of the dyno dynamics is that they've calibrated it for different cars and different dynos. If you have a 350z and you want to dyno it they can print out mustang dyno results, or dyno jet results, or dyna pack results. Since everyone quotes dynojet numbers they put in a factor for the dyno to spit out dynojet numbers. This factor was explained to me by "Under Pressure". It is a different factor for different cars. This has been discussed at length by Phunk, Under Pressure and Sharif on my350z.com.
Did you see the dyno sheet? I dynoed on a dyno dynamics and got 388rwhp. 2 days later I dynoed on a dynojet and got 364rwhp with a lose belt (hitting 1-2psi less than 2 days earlier). I think the two dynos would have been pretty even if I was hitting full boost on the second day, but as you now the GATES belt slips after the initial install and you have to tighten it to get full power out of your S/C. I drove ~550 miles and the belt stretched, thus the reason for my variances.
Randy, why are you going around questioning everyone's dyno numbers and 1/4 mile times? You were just questioning the guy with the Stillen S/C in the coupe forum, now me? What's the problem believing that with better headers, stock wheels and a smaller pulley that my numbers would be better than yours? What PSI are you running at? (gauges would tell you this)
Where's the love bro?

Here's the data... http://www.my350z.com/forum/showpost...4&postcount=15
Last graph was at ~7psi of boost and the lose belt.

So from now on you'll be known as "Man with green rock in Vortech".

Sorry Randy, I wasust bustin your *****. Sometimes that's hard to do over the internet, sorry bro if you were offended.
Well, I just took two xanax and all's well.
The dyno dynamics dyno is SAE corrected and it is a load based dyno. I'd also like to mention that the Crawford Headers are helping me tremendously with FI. I'm hitting 1.5 psi of boost less than G8tor20 and I'm getting over 15rwtq more than him too. Just imagine if I upped my boost to 10.5 psi with the 2.87 pulley and got my car a little more lean up top like his is!
Then we'd have the same boost, same A/F and we'd really be able to see the benefits of my breathing mods.
The 3.12 pulley adds about 30-35rwhp and 25-30rwtq according to pre/post dyno runs done at CP Racing when compared to the 3.33 pulley. If you got a good set of aftermarket headers AND the 3.12 pulley you would be good for another ~50rwhp and ~30rwtq (up top).
When you posted your dyna pack results about a year ago I knew they were WAY HIGH when compared to the dynojet results. When the CA guys had their dyno day I made a mathematical comparison (crude but effective) between 2 stock cars, one in FL on a dyno jet and one in CA on the dynapack. That dyno read more than 20% higher than the typical dynojet if I remember correctly.
When we had our last CFL Dyno Day this last May, I contacted dynapack and requested the closest dynapack operator. I was told that there wasn't one in the state of Florida. I really wanted to dyno on the same dyno as the CA guys did just for comparison purposes (plus I knew that we had 93 octane and our numbers might be 1-2% higher than theirs).

I might break something.
CPR tuned Vortech, 395 HP & 340 tq.

Also, don't forget to add a lightweight flywheel to the list above. That will definitely make things more interesting.
