Hi Went to the FOC UK picnic at prescott hill climb last weekend, where we could drive the hill, to cut a long story when pulling away the car accelerates very slowly until I hit the around 3000rpm mark,then she flies. I have read about a plugged cat on the forum, the take off at 3000rpm seems to correlate with the bypass opening, which made me think maybe this is the problem. can anyone offer any advice, before i take the cats out to check rob
I had my cats replaced with Hyperflows and my exhaust headers replaced with Fabspeeds and I still notice what you have described above. It almost feels like turbo lag. I am beginning to think that is acceptable behavior of our beloved 355s.
Not sure if there is a problem here as the 355 doesn't have an abundance of low end torque. If I was trying to launch an F355 from a dead stop quickly it would start at and never fall below 5k rpm.
I think if you had a plugged cat you would see some CELs or OBD codes. My 355 is 100% stock with no manifold/bypass/cat/etc. issues and below 3K it feels sluggish as well. In fact it (yes they do have "moods") feels very unhappy below 3K. 3K to 6K is the sweet spot and it pulls/sounds awesome and then above 6K to redline it is an otherworldly experience I can only rarely enjoy. Based on my "all stock" experience and the earlier post from the gentleman with properly-coordinated aftemarket components exhibiting the same bahavior I think it just the nature of the 355 being the first road car that can pull to 8600 RPM and not come apart Enjoy and keep it above 3K - Cheers
i agree. if you keep the rpms to low when letting out the clutch the car will bog then feel like turbo lag. feather it and get into it sooner mate.
