Took it out and it made no difference what so ever. Leave it in, it's there for a reason.
Look I'm new to this sight but I am a mechanic don't take your bellmouth put if u do be prepared to Reco your moter as it will burn out your rear cylinders and your valves as they put it there becals the rear cylinders weren't firing correctly u can modify it bye cuting a small portion of the top of the bellmouth off but uther than that you are crazy to compleatly remove it
Vn S1s never had em mine cops a hard time with 100hp of gas jammed down it's throat and I've never had an issue
took it out , next day blew a hole in my muffler dnt know how and my fuel gauge is dropping twice as fast , runs rougher , ive been staring at it and it actually stopped for a milly sec like it missfired
I remember you saying you did the inlet manifold gaskets at the same time.
Did you torque the inlet manifold bolts correctly (e.g with a torque wrench), if you do them up with a standard wrench or spanner chances are you will over tighten them and damage the gasket, the car will then run rough as you have created a giant vacuum leak.....I see it far too often with V6's, terrible design those plastic gaskets.
Removing the bellmouth shouldn't cause the issues you are describing.
I took mine out a while back and observed the results....
Prior to removal the rear 2 plugs were getting a little foul (not sure why) so i thought if the rear cylinders lean out a bit like people say it should be good.
So i took it out and then drove about as usual for a few weeks. Engine idles fairly rough but got slight increase in low end torque. I like to rev the crap out of it and it sounds good up high, maybe better than before.
Then i took out all spark plugs and did a check. They're all spot on. Fouling gone on rear 2 they look tan like all the others.
I searched a bit on here too and i remember a post by greenfoam (i think, could even be inside this thread) where he says the bellmouth gives good air distribution at idle but suboptimal at high revs. With it removed you get good distribution up high, but suboptimal at idle. I can see why Holden decided to fit one now.
yea had 2 go buy a 3/8 torqe wrench jst 4 the job did everythg right, tho i shouldnt put sealent around the gaskets ( coolant passes ) , i did put it in the four corners tho, how do i cheack 4 vacum leak? 2 my understanding u get a piece of hose (my garden hose do? ) and put it 2 ur ear and cheack around?
probs gona cut the bellmouth it and put it back in,
Make sure you take note of the dates on these threads - it's considered poor forum etiquette to dig up old threads. Especially for no good reason.
Considering the post you quoted was quoting vehicles from the U.S., and the fact that there are only small differences in the quoted power I'd say the difference is because of setup and tune in the American models.
^^ What he said!
I thought shovels were banned now?
Na just locked in the shed...they are need sometimes to dig through the .................
but there are still plenty of spoons who can dig , just takes a bit longer .
