Dynoed my car (revup with cams)
Regardless of the numbers you post, the increase with cams will be significantly more when you have a higher CR. That's what the JWT's are made for either f/i or high cr n/a.
Alberto may be a bit harsh with the words, but he's giving you some real world advice. I wouldn't have posted that either, especially on this forum where people are quick to judge.
Name calling is definitely a sign of immaturity, so lets try to keep it clean.

After we road tune im going back to the dyno in a week or two, then ill have actuall numbers on it. It should make power all the way too 7000rpms with no problem. It drops off because of the 11.9 afr.
I am waiting for a utec to tune it with, so no there is no engine managment right now. The car is running off of the stock ecu on the dyno and right now. It shoots flames out the exhaust when shifting at redline from it being so rich. Ill road tune the fuel settings then ill do the ignition timing on the dyno, im just intresed to see what i can get out of the cams NA, and it will be good for other people staying NA because they will see from my example that they can make more power with more compression, so its not a worthless endevor to me.

... so then this thread is even more useless than we all thought!? i didnt think that could be true!
lets sum this up.
we have
A. a broken dyno
B. no pre-mod dyno sheet
C. less brain cells than when we started this thread!

Glad you are going back to redyno on a properly set up machine. Only thing that makes any sence on this dyno is hopefully the power curve (ie: shape of the curve). That looks pretty good. Until you tune it so it's not pig rich and the dyno is right it's hard to comment on anything else in any meaningful way.
An unloaded Mustang dyno typically outputs higher numbers not lower... Its the entire principle behind the Dynojet vs All discussions. The Dynojet applies no real time load to the wheels and is essentially a fixed mass being rotated. A Mustang dyno that is not loaded does the same thing. You are spinning just the drum minus any load at all from the counterweights/brakes on the drum. The only way you should see higher numbers with the loaded Mustang is if the input weight for the vehicle is off as Mustang dynos apply load based on the input of vehicle weight or the operator changes the correction factor to skew the numbers..

I maybe wrong on this . But in a simulation mode , Wt. and all the other numbers play a part on the load that is put on the rollers , done for tuning . But in a power curve mode , more load is put on the rollers to keep the rpm ramp up to a set number of seconds.....600rpm every 6 seconds...something to that effect .

I had though the operator put in the Wt. and numbers for the weather conditions before every run we did in simulation mode [ tuning ] You really can tell when the dyno is in the power curve mode . Seems like the car does not gain rpms half as fast .
