my 1m feels slow

Bad fuel? Maybe carbon build up? But you don't have many miles. I would throw in some new spark plugs and see how she drives. Maybe your clutch is slipping?

nostalgia is a strong thing. could be the car though haha

[cammula]

that porsche might have redefined your definition of fast.

Why don't you put it on a dynometer, and see for yourself exact power figures. If it is down on power the investigate why.

If its not down in power, you'll find yourself attempting to diagnose something that doesn't even exist.

Had an experience with power loss on mine but it was after I heard a pop when accelerating. When I first checked under the hood for the charge pipe, all seem ok. After a second look, it actually cracked near the clip. There were no codes at all. Took it to the dealer and told them about the charge pipe. First they said its fine, I told them where it cracked and they confirmed it. Perhaps, it cracked near the clip.

Differences in ROM versions? There have been revisions. When mine was updated from IKCOS to IKMOS even the dealer commented that the car sounded different. It's been a year, but I don't recall feeling a difference on the road.

Wallnut blast and new spark plugs should do the trick.

The car only has 4000 km on it...

i really don't think there is anything wrong with your car. It has such low mileage.

i think your mind has been destroyed by owning a 911 Turbo.

sorry, mate!

go rent a 120hp hatchback for 2 weeks, put the 1M away. Then return the rental hatchback and drive the 1M.

True... missed that part
Has the OP had it on the dyno?

By any chance one of these two yours?

It's worth noting that these engines do break in and loosen up after a while - perhaps you are just feeling the friction of a new engine?

I finally found a pristine white 1m with only 2,800 km on it. I now have driven 1,200 km on it, but I don't know why it feels much slower than my last car. The last 1m I had on 2 gear and 3 felt really strong even wheel letting go on the gas it had a sort of boost pressure sound and pulled really hard. (no bov installed or nothing as it was stock). this one feels sluggish.

I took it to the dealer to have its oil changed and told them about the "slow feel" but they found nothing wrong no loose charge pipe nothing, the car is not throwing any codes. I know dealers down here don't know much therefore I decided to ask around here.

Is there any other thing I could check??

right now Im having mad dad miss and akra slip on installed. I might buy a p3 gauge to check boost?


thanks

Will post pics when I get it back from the shop.

First off.. ALWAYS BET ON BLACK! Sounds like you did... and ya sold it (DOH! ) and now you've got a slower, white car..

1- Possible charge pipe issue - check connections - probably worth checking the dealer's work..

2- possible adaptation issue. The car has only 1200 Km in your hands right? Looks like you need to start it up and drive the crap out of it hard about 10x In a row and see if it begins to adapt and provide more power.

3- go to a dyno and check output.


If all three above check out, then it sounds like your "trade in " light has just came on again ( seems like a frequent issue for you! )
and perhaps it's time for you to pick up an M4.

I think the 1M always feels pretty fast, even after driving 911 turbos which I already did.

It sounds strange to me that you didn't pull from the SQ5, the 1M does ~10 secs 0-160 kph and ~16/17 secs 0-200 kph and the SQ5 takes ~14 secs and ~25 secs to reach the same speeds. Unless you only tested from 0 to 100 kph you should pull away quite easily.

[blackmist222777]

throw a tune on it and then update us.

[IEDEI]

i think you should have it painted Orange.....then it will certainly be much, much faster

haha just kidding. hope you figure out whatever is making it 'slow'...it should definitely be quicker than an SQ5, IMO.

I would add fuel injectors to your list of possible sources....mine were 'leaking' when i got my car and had them replaced....which freed up some lost power.

What was the mileage on your when you picked it up?

significantly higher than the mileage the original poster has, i suppose....around 35k miles when i picked it up. at 53k miles now.

[Jay-K]

with low km's like that I doubt there can be a problem (not impossible)

but i am pretty sure like some others,

its the 997.1, it redefined your definition of FAST.

anyways, congrats and hope everything works out well.!
