car looks very tidy indeed mind you i'd be surprised to see a 1.8 16v on 40s making that sort of power but i think 170 is defo attainable
Theres so much more room for filters on a mk2 on carbs than there is on a mk1 [:^(] Sweet looking mk 2 m8. Any idea what jets and emulsion tubes your running? Nik
HI JUST SOLD THE CAMS AND CARBS AS THE ENGINE WENT POP, GOING BACK TO INJECTION NOW AS CARS TO THIRSTY AND NOISY FOR DAILY USE, WOULDNT ADVISE A CARB SWAP TO ANY ONE IN THE FUTURE AS ITS VERY ON OFF, THROTTLE ON THESE ENGINES Edited by: rob.dren.1981
Hmmm. Absolute bullsh[/i]it unless it's not tuned properly, which might also explain your poor fuel economy. What went wrong with the engine?
well ive got 2 engineering qualifications and it was tuned twice by d an b carburettors of nottingham, who funnily enough specialize in these. Edited by: rob.dren.1981
OK, point taken that came across as a bit rude and I apologise. It's hard see light-hearted banter on the internet. I'll try and explain my point. You say that the throttle's an on/off switch with these engines, which I know isn't true because I have them on my 2.0 16v. You didn't specifically mention the cams, which will obviously affect the peakiness of the power curve (which isn't quite the same as an on/off effect to the throttle pedal), but with this kind of setup it's 90% in the jetting of the carbs and you can get around the problem by setting the engine up for a road spec. If the carbs were set up to chase the peak power figure (like a race-spec setup) then the driveability will suffer as a result but there's no reason it shouldn't be possible to find a nice compromise between peak power, good torque spread and nice driveability for a road car. There are some weaknesses to carbs on these 16v engines but it should be quite possible to tune them to give more low down torque and a wider spread of power than on an equivalent K-Jet setup. This is my dyno plot (standard 9A with just KR cams and Dellorto 40s): <a href="http://img.photobucket.com/albums/v521/gs3333/rr.jpg" target="_blank">Link </a> The short inlet manifold shouldn't necessarily be a problem. You can fit a longer one or longer trumpets if you move the radiator a bit. Now can we be friends?
ok mate may have gone bit off the handle. to be honest i got fed up of the damn thing as well ive had carbs before and they worked well on that, as for this, maybe it was a tuning issue, maybe not, but the hassle involved in them outweighs the positive in my view. cheers for apology Edited by: rob.dren.1981
i never had one problem with the mk1 valver on 45's it always sat ticking over bang on 1k and it was only set up the once,i think most problems will come from old carbs being a bit tired and worn on the spindles etc? neil.
this idled at 1k too and the carbs were fully rebuilt. any ways putting new 16v in for now, if any one knows of a g60 engine and ancilliaries let me know, thanks
