Hey guys, if you recall I had a dyno session a while back and was disappointed in the numbers realized, but I saw a lot of room for improvement. Leaning out the AF ratio and the motordyne spacer did wonders! I had TS tune the car some more and the results were staggering!

All dynos were performed at the same dyno facility and is a dynapack system. I know that some will argue that a dynojet is better than a dynapack, but the main reason that I am posting this is to show gains as no one can really argue this. I personally prefer dynapack for more accurate hp readings for gains and tuning.

Here are the results

AF Ratio (AF readings on the graph are 1.0 higher than actual readings)

Dyno Mean Numbers

Rick
you have some good numbers there

 

Carerra's need to look out for you brotha..

 

your old mod has two leak, and now you have one left
are u going to fix it? What different do you expect it to be?

 

what year is your car? what would you say are the best bang for the buck mods. i mean MD obviously, but what else do you feel like really justified its price?

 

Why did you decide to go with one step colder plugs?

 

I have a leak on one of my test pipes I will get it welded up for the next dyno session. I am going to try to break the 300hp mark with a new ignition gadget that Sun Automobile came out with and I am going to build a custom velocity stack for the ARC intake

Hands down the Test pipes and plenum spacer from Motordyne was the best bang for buck. The TS reflash brought it all together nicely

Here is an excerpt of a post I made on another forum for my NA picks:

"My picks for basic NA bolt-ons without going internal:

Intakes: Stillen, Gruppe-M, ARC for high end power or Cold Air units for mid-range power. Stay away from short ram intakes that are not enclosed.
Headers: Crawfords if you want to extract max power. Strup, DC, etc if you want cheap hp and only looking for bang for buck.
Cats: Crawford High flow cats or Test pipes
Engine Management: Technosquare reflash, Utec for those in high altitude, or Full standalone Motec for full tuning
Throttle Body: 350evo, proflow, crawford
Plenum Mods: Motordyne 5/16" spacer with Iso thermal system for 287 HP motor and MREV mod for Revup motor, or Crawford Cast plenum
Exhaust: JIC single exit ti for max weight savings, Power Amuse Ti
Gears: 350evo 3.917, Central 20 3.917
LSD: Nismo, Quaife, Kaaz, etc
Underdrive: UR Crank Pulley
Cooling: Koyo Radiator, Motordyne Coolant Control Valve or Motordyne Copper thing."

 

I went with one step colder because I used to run a 75 shot of nitrous a few months back. I kept them in place since I road race anyways and it adds some extra insurance

 

Will the one step colder add any power?

 

thats awesome bro

 

Doubtful. Just extra protection especially when I had n20

 

I dont think dynopak are more accurate bc u take off your wheels and measure hp without the extra variables. Most accurate would be your mustang and most common dyno readings come from dynojet. Try dynoing it on a dynojet and I'm sure it will be around the 260s.

 

More accurate as in what terms? Probably to see what your actual whp is with the tire/wheel/camber/toe combo you have, but if you are comparing HP from each car that particular day and comparing gains from mods, a dynapack is more accurate. The only other method that would be even more accurate is an engine dyno with the motor completely removed from the car. There is a reason why many tuners use dynapack systems such as Turbonetics and Jim Wolf. If I dyno'd a dynojet, it would be around mid 270's possibly high with my track 17 with r compounds.

 

where can you get an ARC intake...never seen one before...you have any pics?
