Dyno Differences
What are the main differences between the Mustang dyno, the Dynojet, the Dynapack, and any other types of dynos I failed to mention.
I went to go get my car dynoed today at Advanced Motorsports and I was pretty disappointed.
I averaged about 162hp.....which I thought was what the TSX ran stock.
The thing is...I'm not stock at all.
I have the Injen CAI, Comptech header, and the Hondata reflash.
This dyno was done on a Dynojet.
The previous dyno I had was done about a year ago at J&D Performance (If I recall the name correctly) in Ontario on a Mustang dyno.
At the time, I only had my Injen intake in short ram mode and that was my only performance mod.
I averaged about a 174hp...which is what I expected the gains to be from stock after my intake.
I was actually expecting my numbers today to be around 185hp or so.....
Did my car lose power with all my mods or is it the difference in the dynos?
Which type of dyno is most accurate?
I hope you guys can explain to me why there is such a weird change in my HP numbers.
Thanks

Dynos are not comparable to eachother. Realistically you need to dyno on the same machine under similar conditions to get meaningful results. The dyno you got 162hp on may have said 150hp before your mods.

Hold up - I've always thought mustangs slightly UNDERrate power due to the simulation of wind resistance and other environmental factors, while dynojets are about right as they are NOT eddy current drums (they don't use water to load the resistance) and Dynapack dynos overrate actual power as they remove the rotational weight of the wheels.

for bragging rights - dynojets are the way to go.
for tuning, mustang dynos are the way to go

With a Mustang dyno I got higher HP with only my SRI
With a Dynojet dyno I got lower HP with CAI, Header, and Hondata

First thing you have to remember is that factory rated HP & TQ that appear in the owners manual and window sticker are crank rated. They are not what the car digs into the pavement through friction coefficient of oils, gears, drivetrain, transmission and rotational mass of the wheels.....A dyno measures the performance from either the wheels (dynojet, dynomite & mustand dynos) or hubs (dynopac).
See 2 previous posts.

I'm going to show my ignorance. Are chassis dyno's corrected to the same "new" SAE standard that hp is being figured with for the '06? (I.e., the 10-odd hp difference between the "old" 200 and the "new" 205.)
Also, is there a rule-of-thumb for converting the Mustang to flywheel hp? I'm about to make my first trip to the local dyno (they use a Mustang) and, since I didn't do a baseline before modifying my intake and hondata reflash, I'd at least like to guesstimate a comparison to the stock "200 hp" the '04 supposedly had under the "old" SAE standard.
See, told you I'd show my ignorance.

I had a dyno done on my TSX today -- the local shop was running a special 3 pulls for $35 total. In 4th gear, max was 163hp @ 7250 and 138lb-ft @ 4000, about what I expected given that my only mods are a home-made Icebox and Hondata reflash (which doesn't raise the peaks so much as broaden the curves). It was on a Mustang dyno, the guys running it said you'll lose about 20% on a manual tranny. So that would come to 204 hp and 173 tq at the crankshaft, about what I figured.
Anyway, it's great to have a baseline for future mods (planning on a header & high-flow cat, and maybe a CAI). The guys at this shop, who do a lot of tuning and engine building for local racers, said what I've read a lot here -- you can't really compare numbers on two different dynos, you have to tune using the same dyno and as close to the same conditions as possible.
