Three pulls, completely stock:

1) 147.27 hp 145.89 torque
2) 147.87 hp 144.10 torque
3) 147.10 hp 144.84 torque

Ill try and get the sheet scanned and posted up when i get to work Monday.

 

Auto???

 

5-speed

 

seems a little low

 

ouch those are low

 

Not sure why.
It was a little cold though, about 52*

Had a 2.4 auto there also, it was at like 127hp and 115torque.
Brought an HHR SS, the Auto Turbo.. Only hit 212Hp, 188torque

 

What type of dyno was used?

 

"low" is a relative term and all based on the type and calibration of the dyno. If the car is totally stock then those numbers are spot on.

 

Those are pretty much what I layed down stock on a mustang dyno two years ago.

Not bad

 

He probably has 10 to 20 percent drivetrain loss. So those numbers arent bad for a stock car.

 

Still new to the whole dyno thing...
buddy just told me it was a dynojet.

What do you mean?

 

Thats good that you had it done on the dynojet. The mustang dyno would post higher numbers because it bolts onto your hubs. A dynojet has your wheels and tires on rollers simulating the road and it actually measures power to the wheels rather than the hubs.

Drivetrain loss is the horse power and torque lost due to the rotational masses of the engine and trans every car has this. Ways to lessen this would be to use a lighter weight flywheel, a lighter crank, and so on.

 

sorry but you are terrible wrong


And to the OP....numbers seem spot on.......they are slightly lower then mine w/ Inake, axleback

 

If you estimate 15% drivetrain loss, you get exactly 174 crank hp, which isnt very far off from the rated 173!

 

wait wtf r u saying what r u driving a 2.4 or a 2.2?

 

mustang dyno is more accurate acually it calculates alota other **** in dyno jets are usly on the higher end

 

Thanks for the explanation.


I really just wanted to try and get a 2.4 stockers dyno numbers. Havent found any looking around.

Posted in the 2.4

Im driving a 2.4

 

too bad its incorrect.....looks like he's spewing to much stuff he's read and doesn't fully understand

 

LSJAY is talking about a Dyno Dynamics style dyno where they run it off of the hub. A Mustang dyno just like a dyno jet has you rolling drums to get the numbers. But a mustang dyno will put a load on the engine just like real street driving does to get real world numbers. Where as a dynojet has just the weight of the drum you are spinning. For the most part. Only thing is with a dynojet they can use SAE calculations to get more consentient numbers no matter where you may be in the country.

 

^^Listen to this guy he knows what he's talkin bout not LSJAY.

 

You are describing Dynapack dynos that bolt to the hubs. Mustang dynos use rollers and also feature loading capabilities closer to real world than Dynojet.

Edit- Redfocz beat me to it, but I think Dyno Dynamics also uses rollers.

 

If you watched them do two auto cars -- how did they get the auto tranny to stay in 3rd gear for the tests?

 

those numbers are a lil off...maybe it was a 2.2 auto..no way in hell is at 2.4 auto that low..ur numbers should be a lil higher..

 

^^chalk it up to dynos being calibrated different. I know after i got my tune w/ Intake and exhaust i only pulled 159whp but still mustered up several 9.6 1/8th miles times @74 when folks that dynoed higher (some stock some moded) ran slower times.

 

thats so crazy to see that major number difference.
