Dyno'd the LS Today...

2001 LS8 Sport

On a Mustang Dyno

190 HP @ 5900 RPM
190 TQ @ 4300 RPM

A 2002 Mustang GT with a few mods went before me and pulled a 202HP so I am not dissappointed at all.

Anyone else have any Dyno numbers they would like to Share?

numbers seem weak - most of us pre-03 LSes with exhaust and intake are running 218+hp and 243+ ft-lbs - without any power adders.

of course we are getting bigger numbers with NAWZ..

If you calculate 11.55% for HP and 12.95% for TQ increase for a Dynojet run, I was putting down 219HP & 246TQ but I did not request the dynojet pull I requested a Mustang Dyno pull (fully loaded) and made the 190.

There was a modded 1998 Mustang GT that only made 195HP. I won't complain.

Most People don't want their egos bruised by posting a Mustang Dyno number. They would much rather beat on their chests with a Dynojet number because it makes them feel better.

Mustang Dyno's simulate a full load and calculate in the weight of the car. This helps them decide how much friction to use on the brake attatched to the drum.

Dynojet uses inertia to simulate load and bases its numbers on how fast the engine will accelerate from 2000 RPM to redline.

To me, that is cheating and should only be used to make one feel better about their car.

Not one single Mustang owner there complained when they only hit 195 to 205 on modded 1998 to 2002 Mustang GT's because they know it is a more realistic number and not an inflated ego stroking number from a dynojet.

In other words, a dynojet will tell you what ishould be available to use at the wheels, a Mustang Dyno will show you what you are truly capable of using at the end of the day.

Take your car and strap it to a Mustang Dyno, it will almost break your heart the first time you see the numbers.

dude - we all understand the difference between absorption dynos (Mustang) and inertia dynos (Dynoject/Superflow). I agree with you that the Mustang is a better / more accurate number.

However - I have had my LS on both - several times - and your numbers still seem weak. the differences between my Mustang and Dynojet runs were - at best 5.3% different - at worst 7.9% different - not the 13% you are using........

Those were numbers that I found by searching the web...

I should know better than to trust numbers I have found from the web though...

After reading the some responses from the other guys who ran that day, they all seem to think there was something "odd" about all of their numbers.

One guy in particular with an 03 Cobra has pulled a consistant 445 on many other dyno's and yesterday it told him he only hit 424HP???

I think I will try another dyno and see what happens.

More later.

yep - the Mustang is the right dyno to use - and you sound knowledgable about your car - hope you can get it into 204 - 210 range!!!

I take my passion for cars very seriously as I know you do.

190 on an LS with a couple of Mods seemed week to me as well. I felt much better about those numbers when modded Mustang GT's were barely beating me out. But the more I look at my numbers and mods and from what I have read from people like yourself, I should have realized at least moderate gains from my mods.

That being said, if indeed I am only putting 190 to the wheels, then I am showing a loss of 35%.

Knowing that an AT will lose a great deal of power, I am not convinced that on even the worst day in history a 2001 Lincoln LS8 with 33,000 Miles will lose 35% through the drive train. 25% is conceivable to me, hell, I would even go as far as to say that I could possibly lose 30%, but I cannot conceivably believe that I could lose 35% through the drivetrain.

That being said, if I would have at least broken 200HP, I would probably not make a huge deal out of it. But I have read in other threads that an intake and exhaust on these cars can net roughly 14 HP. If this is true, than I am losing even more than 35% and it is actually closer to 40% to 42%.

Now, I know environmental conditions will adverly effect the outcome of any dyno pull, so I will tell you the conditions and you tell me if it should have had a negative impact on the outcome.

Elevation = 500'
Outside Temperature = 28 Degrees
Temp while on the Dyno = 32 according to the cars external thermometer
Humidity was 70 to 80%

All ACC were off
Texaco premium 92 Octane gas
A/F was 14.7 accross the entire run.

Any thoughts?

I have followed a lot of your posts and hold your opinion in high regard, I just feel that these numbers could possibly be inaccurate. Or perhaps my ego is feeling a little bruised at the moment.

If it did only pull 190, perhaps I should inquire at my local dealership as to why this could be.
