2 ltr top end rev range...bit rough?
wiseoldub - May 31st, 2010 at 12:23 PM

just put a std 2 ltr into my 74 ute and she runs great, but seems a little inconsistant at the upper end of the rev range. around 100 km's it seems to hesitate just a tiny little bit. I have had a similar symptom with a previous 1600 untill i replaced the coil, but the coil on this one is new. I am running std carbs and an empi quiet pack exhaust. the next step is a set of 40 IDF Webers to see if it helps. I assume this will open up my top end a little and provide a little bit extra grunt? any thoughts?
all help appreciated

i have found thiming for a good top end is critical i was having trouble with a dead top end ws told it was fuel so i chased fuel for a week than timed it only a few deg's but what a differance

Josh I've now got a set of 45 drla dellortos have run 40 idfs and 44 idfs on my bus type 4 but still finishing bug bought a 57 splittie so money is going into that and trying to finalize bug just bought a set of throttle bodies to go fuel injection. So many little things to do to finish bug.

I got some header pipes that replace the heater boxes got them from sharpbuilt not the best but only used them to break In an engine and I mated a type 4 thunderbird to them work good I also have my set of 40 idfs with manifolds linkage and filters that Im about to put up for sale. As for 2nd hand type 1 shroud conversion I do not know of any sorry.

thanks mate, I am looking for 2nd hand to keep costs down and maintain the less than perfect rat condition of the rest of the car. I am very interested in those webers!!! please let me know how much to part with and how they went on your car!
cheers, josh

Your problem may also be fuel related Josh, a vague or hesitant response at 100 km/h can be a fuel delivery issue if the engine seems to pull through the lower gears ok, but has some issues when fuel demand is higher. Test fuel pump output pressure and volume when the engine is hot.

i am running a facet electric fuel pump that should be putting out up to 7 microns of fuel i think. I will check it out!

What about the strainer in the tank feeding your super dooper pump?
