Are there any 2.4 dyno sheets or any common knowledge of what they are at the wheels stock ( or with minor mods)

 

ill let you know what mine does in march when it goes to the dyno, but to the best of my knowledge they put down about 150whp stock

 

If you check out the performance technical section on solsticeforum.com there is a sticky thread with dyno numbers. Those values of course are going to be lower then what you get on a Cobalt due to the Solstice being RWD. The Solstice sees about a 21% loss in flywheel verse wheel HP netting on average 140HP to the wheels.

I'd really like to see some non-Solstice graphs though because we have a really nasty dip in torque about 3500 RPM that we're trying to determine the cause of on all the cars.

 

im dynoing mine in march as well...will post info afterwards.

 

what day in march? i should be getting mine done on the 25th with my I/E mods to see how the 2.4 likes the bolt ons

 

I thought that since the 2.0 S/C was underrated that the 2.2 and 2.4 might be as well.

 

its possible but we will have to find out by hitting the dyno

 

ONLY the 2.0L is underated. That's also due to the nature of forced induction as well. Forced induction motors are able to work much more efficiently then a NA engine which looses a lot more power under load.

 

I thought someone on ************* has their car dyno'd. It was between 150hp-160

 

ims still waiting to see a graph.

 

injen has a sheet posted before (stock) and after there intake instalation

 

Right here guys. 2006 2.4L dyno results. I have full magnaflow 2.25inch and injen sri. https://www.cobaltss.net/forums/2-4l-le5-performance-tech-46/dyno-results-2-4l-13327/

 

I will attach to you Dyno test from Chevrolet

what

 

i thought they put down 171 stock

 

thats the power at the engine and it could possibly be more than that but they sre getting like 150-160 to the wheels

 

I think he was trying to attach this.

The GM official engine dyno. Which since people seemed to be confused by flywheel adn wheel horsepower, this is the engines rated flywheel power which is the value before drivetrain loss which becomes the wheel horse power.

 

cool then i see now

 

how much whp and torque will a auto probably have?

 

youll find out when i post my dyno up later this month but im not stock if that matters
