Wtf!!!!!
so im pissed here is the story. i dynoed the car a while back and put down 151whp with just a intake and catback. On sat at the midwest meet i dynoed it with everything in my sig done and the highest i put down was 140, WTF!!! i was so pissed. i was thinkin like at least 160-165. what could be the reason for such low numbers the only thing i can think of is the clutch is starting to go and the guy burned the **** out of it pulling it on the dyno. i just thought maybe it was slipping cause he burned it so bad. any ideas?

dont they only dyno in one gear? so your clutch prob has very little to do with the low numbers
likely what you have here is either:
1. different dyno (different kind, or calibrated differently then before)
2. different weather conditions (heat soak, higher humidity, high temp, etc all result in lower numbers)
Post up both graphs, I HIGHLY doubt the catback and intake reduced your whp

never said it was the same type dyno. i dont remember the first kind of dyno it was like 3 years ago the latest on was a dyno jet. it was really humid but even tho how can i add the 2.4 mani a throttle body header downpipe and a tune and lose 11 hp.
it was 93 octane on this one and i have no idea on the first

I dont think you have to worry about your car losing power. You cant really compare the two runs when your baseline was hundereds of miles away and 3 years ago.
Chalk it up to different conditions. If it really worries you that much, go back to the original dyno and see what happens.

If you're going to use a dyno as a measuring stick for your modifications, do it more scientifically - always use the same dyno and if you want a before/after estimate, then dyno as close to (if not immediately) before and after you put a mod on. THEN you'll really know what is going on with the car.

sounds like a different calibrated dyno as most of the people responded said...my buddy dynod his evo on a dynojet and got 291whp...the other week he had a proper tune and a couple supporting mods and the dyno read 278whp...owner of the dyno said his dyno read 25% lower than a dynojet so yeah...sounds like you were on a different calibrated dyno

An Engine does not run the same everytime you turn it on, somedays it runs better than others, I know there are times when I boost my cobalt it feels like it laggs and on others I feel an incredible pull lol

well you only have 160 at best so who cares lol j/k.... i was there and saw that run... nice car btw... i've heard that dynojets are usually 15-25 whp higher almost like the factory rating at the crank... no idea whats going on there, but if it helps any, i've had mine dynoed on a mustang dyno (stock) and had 243 whp, but on a dynojet it read 258whp. dont know how you're losing power though, doesnt make sense.

I heard that some speed shops tweek their dyno like a gym will do their scales as they want to make the customer happy.
Not sure if that is what happened here, but I agree that it has to be the two dynos are calibrated different.
I hear these are more for before and after result monitoring than really getting accurate output numbers, but I could have been told wrong info. Sounds about right.
But as such, I would go back to the original dyno you went to for an output comparison.
I would also wonder if a new mod shifted your output a little.
Does your car run better than before the new mods is what I would go off of.
