I agree Dave. My oil temp gauge doesn't even begin to move until 3-4 miles. |

I have been told by Ferrari techs that the motor's clearances, etc. were designed to perform best when fully warmed and it takes a while to get a Ferrari motor with 10 qts. of oil really warm, especially in cooler weather. If you take your car out for a 3-4 mile ride, you never reach full opertating temp.

I also have an '89... like most of you, it runs great when it warms up. I've never had any problems with poor throttle response except during the first couple of warm-up minutes. |

Thanks for the responses, and varied they are! I sure wish you guys could have all just agreed with me so I can rest in peace!
Karl, I do run an Ansa straight pipe unless I'm attending a show or the bi-annual smog. It makes a reasonable difference, but nothing major.
Yes Scott, I am running the K&N- Hey! That's my problem! It's all that crap on my mass flow meter! Oh, that was another post...
Anyway, I guess I'm going to have to compare apples to apples at the next event and make some comparisons before digging into the car further- for possibly nothing. (I've done that before!)
Thanks everyone for your kind comments! |

If you really want to feel a difference put a bypass pipe in. I made one for my buudy's and my 86 328s. We didn't realize the huge difference until it was inspection time(every 2 years for emissions).With the cats on it was a slow rev-up.After they are removed....instantaneous rev-up!!!Night and day! |

If your car is equipped with oxygen sensors it ideally should run close to the same cold or hot. If it runs too good when cold it is probably too rich and needs to be leaned out some. In some cases the 02 sensor can be out of calibration and be lying to the computer. This could make the car run worse warmed up. This one will make you pull your hair out. The best way is to install a new 02 sensor if you suspect it to be lying. Keep in mind that when cold the 02 sensor has no effect on the engine operation. |

The big thing is the later cars started lightening up all the internals. The 308 and 328 engines are very sleepy compared to say a 355 because of this. The new engines are like big motorcyles when it comes to free revving. Timing also plays a significant role in this. The best way to make a 308/328 rev quicker is a lighter flywheel and clutch, this often entails a different ignition system though because the lighter flywheel usually doesn't have pickups like the stock one does. Kind of in the middle is swapping for a electronic ignition and keeping the engine stock, this would rev a bit quicker and wouldn't entail nearly as much work or $. |

The 348 throttle response will always be better than a 328 regardless of how it is running. The 348 engine is more powerful and has a better fuel injection, ignition and ECU system. |

my mondial - same engine - runs about 10 times better after about 30 minutes. It is like a diff car |

I have an '86 Euro with much less smog equipment and mine is similar. Not so much slow to get up to a higher RPM but it drifts down too slow for my liking. I would rather have that instantaneous response at throttle blips like a race car. I had other cars which were certainly better at this. |

Jim: Mine runs much better warm. Wonder how it will run with that K&N? |

My 89 defintiely runs better when fully warmed up. It is all stock.

OK you 328 masters, here is a question for you that's been bugging me for some time. As my '89 328 is warming up, a slight push on the gas will allow for a brisk and impressive rev of the engine. Once the temp is high enough, and the oxygen loop "kicks-in", that same push will cause a fairly slow raise in RPM (both while in neutral.) When on the road, performance is better during warm-up, even though I typically don't drive the car during this period.
I've driven other 328's, and noticed the same thing. I have to tell you that the throttle response of some of the more modern cars after warm-up, even the 348's, makes me jeolous.
Is there any way around this situation, or is it simply the good 'ol slow feedback loop and slightly lean (normal)condition that causes this? By the way, no cat's, stock exhaust, clean filters, and good fuel. |
