rpm

  1. No power after 4 k RPM

    Alfa 147, 156 & GT
    Hi! I have a 156 2.0 ts 16v. I got it around 2 months ago. Everything was in pretty good condition for a 21 year old car. The thing is that it was driven 3000 km in the last 2 years so when I got it the engine was weak. I thought nothing about it since I know that happens when a car sits for a...
  2. 2.0 TS imperfect throttle control, slightly jerky at lower rpm.

    Alfa GTV & 916 Spider
    Since I have my car it never behaved right. Facts: - new Marelli AFM since yesterday - car became even worse ( I am not sure if it was necessary - the new unit reads very different values than MES gives as target, just like the original BOSCH unit did, it reads ca. the double amount of air . In...
  3. Smoke over 4K rpm

    Alfa Giulietta
    My Giulietta is remapped and I noticed that with dna on Normal, it is very hard to see any smoke coming out of the exhaust, which is a good thing, but I noticed something on a high rpm. There’s this road I do every day coming home from work where many times I pull a 4th gear up until the redline...
  4. A strange noise when engine running at about 1.5-1.9k rpm. 1.9 jtdm automatic

    Alfa 159, Brera & 946 Spider
    Hi, I have experienced a strange noise. It only appears when engine is running at about 1500-1900 rpm and even then its not always there, comes and goes. It kinda fades in and fades out. When this noise is annoying me, i step on the gas, car downshifts, rpm goes higher and the noise is gone...

    Alfa 147, 156 & GT
    Hi there! My 147 2.0 TS MY2001 hesitates between approx. 2500-4500 rpm. There's also some kind of noise from the engine at theese revs. It runs fine on all other rpm's. I've checked fault codes (WOW Snooper and Multiecuscan) but fault memory is empty. Ideas? //Thomas
  6. Odd noise at around 2k rpm

  7. 2000 rpm

    The Classic Alfa Romeos
    I have always had an issue with the engine not being happy around 2000 RPM, it coughs and splutters. That was never a big problem when I had the 41/9 diff, but now I have fitted a 41/10 axle 2000rpm sits right on 30mph in 4th, I have to change down to 3rd which put the revs up to 2500. Now I...
  8. Getting a 155hp T-jet to 8k rpm

    Tuning & Upgrades
    I'm slowly planning out my engine mods for my Mito. My goal is something about 250 hp maybe with an 8k rev limit. What will be needed to get it up that high? I'm guessing forged pistons, rods, cams, valve springs, what else? And probably a mechanical LSD to get that power down. I've seen people...

  10. Alfa GT JDTm Low RPM Manoeuvring Judder

    Alfa 147, 156 & GT
    Hi guys, Brand new Alfa owner here. Love my new car, it's a great drive! Only issue at the moment is when manoeuvring the car using the clutch only generates a massive amount of shuddering through the car. A couple garages thought it was the clutch assembly, but having being prompted by the...

    Alfa GTV & 916 Spider
    I have a loud squealing noise that starts at 4500 rpm, but only when the temperature is set to cold on the heater. It sounds like a leaking vacuum hose and initially, I thought it was coming from the passenger air vent, but after dropping the glove box, I discovered that it was coming from the...

  15. Gtv v6 rpm too high on tacho

    Alfa GTV & 916 Spider
    Hi just picked up my fixer upper for winter which is a 2002 gtv cup. One of the issues I’ve discovered is that the tacho doesn’t seem to read the rpm correctly. For example at idle it sits around 1100 and 70 on the motorway the revs are 4000 which I thought seemed high for a 6 speed v6 Anyone...

  17. Fluctuating RPM on startup - 147 1.9

    Alfa 147, 156 & GT
    In the above-mentioned video, you can see exactly what I'm talking about. It's a split second fluctuation around the 850-ish RPM mark. Once it's steady, it's not fluctuating - it keeps it steady till I turn off the car. It only happens on startup and the engine temp doesn't make a difference...
