I thought that perhaps that was the cause of pressure build up in my fuel tank.
No that's a different line to the fuel tank

Just plug the line and make it disappear as though it goes somewhere

I took the alt back and they checked it outIt was working, just wasnt exciting cos the little globe i use as the exciter had popped, newbie error by meAnyway they opened it up and it had heat damage pretty bad which means it was working too hardSo i bought a new bosch alt 120A which produces less at low revs so i will need to turn this one a bit faster (changing to serpentine at last...)Below is the output of the 2 alts as tested while i watchedOutback Jack reacted to this -
Mmmmmm I think im stuffed then. I used a 9mm bit and the m10 tap. So that explains why stripped again.
Mmm wonder how a dyna bolt would fix it now :-(
As i said, not as easy as it seems to do a good tap job
Firstly as said need to use the right drill bit
Also you need to use cutting oil (not any lube) and need to know when to pull the tap out to clean and go again
Sharpness of the tap is another variable
Its a bit of an art form which im not good at myself
Helicoil seems to be the last resort

Ok a bit more history...
First alt was a chrome AC delco (had no idea of which alts were any good)
I made custom brackets with the p/s and alt on the same belt
The problem was not enough belt touching the alt pulley (approx 30%) so when revved the belt would fry
To overcome that I put a bigger pulley on the alt which solved the belt issue
Output was poor so went to buy a new alt
Was a bit of mucking around to change to Bosch, so after being told AC delco is ok I stuck with them
Got a new one that needed an exciter, so hooked up a little light to do that
The guts was moving and was pushing the bearing out the back so got given a new one (the current one)
Now this one has held together for a while
I can't remember what output was when it was new but I needed a good battery for the car to last a whole day
I put it down to the bigger pulley not turning the alt fast enough
Having a fresh battery would get me through the day until I got back to a trickle charger
It time I sorted this out so did the test and added up the draw to work out what I need
Ive always wanted to change to serpentine belt so I can turn an alt faster
-
Charging system help
Ive got an AC Delco alternator that is a 80-120 amp (variable)
I put the voltmeter on the back of it and it showed 12.2 volts at idle (not enough)
Its turning twice as fast as the crank so the alt is doing 2000-13000 revs
This is not enough for what the car is drawing
Water pump, fuel pump, fans and ignition have a max draw of 65A
It would seem the alt should do the job guessing total draw from everything is say 100A
How much minimum output from the alternator do I need to run my car?
Do I need to turn it faster?
Could it be a poor alternator?
-
My top drivers side water pump bolt keeps stripping the thread. I have drilled and tapped it twice already and its up to a m10 size now.
Is there anything available like a dyna bolt to use on the hole to hold water pump and alt bracket in?
I think the metal will keep stripping
No offence but how good do you think you are tapping?
Its easy to do a bad job, not as easy as people think
-
I havn't yet but will be switching to a BIG relay and basic on/off switch for mine and deleting the controller.
Did that too, just make sure you dont forget to flick it on lol
That switch always stays on in my car, id rather a slower warm up with all the water at an even temp
I prefer to just leave the fans off for a quicker warm up

^^^ yes good point gerg about timing, very true
My big block can run a bit over 40 deg total (with 98 fuel and not very hot weather)
Learning what detonation sounds like is very important for car enthusiasts
That way you can find where your motor wants the timing
slydog reacted to this -
It will be the fan, poor airflow
Clutch fans were put on from factory for a reason
So to replicate that volume of air, good elec fan/s are needed eg el, au fans or aftermarket fan/s with WIDE BLADES

I know it would be a pain in the arse but to make sure there are no bits floating around I would open it up

Must go to an engineer first to do this in this car
You will need to pass emissions, lane change and torsion test
Will cost 2.5 to 4 depending on the engineer
Edit: You might need cats depending if its an '85 car or '86

Looks awesome James
Those return springs look very heavy? Too heavy?
Personally i would only use 1 unless at the drags where 2 are required

we've just finished changing my old mans 393 clevo from a solid roller to a hydraulic roller, in 30,000ks it's ruined 2 sets of lifters,one cam and 5 rockers, clevo's and big block Chevy's seem to have a habit of causing excessive wear and tear on solid rollers from some of the stories I've heard, if it's going to see plenty of street miles go for a hydraulic roller, essentially set and forget (in saying that comp and lunati are both doing extreme duty solid roller lifters now so they may have overcome the issue now)
Any motor with solid roller and lots of idling/street miles = sore lifters
But now they have the bushed lifters (well Isky has been making bushed for a long time)
These bushed lifters (rather than the needle pin bearing) last a long long time

Yes with the laptop, just choose the fuel or manually choose which stoich fuel ratio you wantI do understand that. Is there a switch on the guage itself to change between unleaded / LPG / ethanol?
(It comes with software)
-
Is that compatible with e85?
Yep
Only leaded fuels stuff the sensor
-
expect to keep frying top gear whether you go c4 or c6
A stock one yes but not if its built right
I'd recommend a well built C4
As xdwagooon said, shifter is personal
If the trans is set up for "chuck it in D and drive" standard shifter is fine
If you get a manual valve body, a hurst or B&M is more user friendly (lots to chose from)

Ive got this kit and very happy with it
http://www.dynotunenitrous.com/store/scripts/prodview.asp?idproduct=150
I liked this one cos the display is very small
I plug in a lap top at the drags and log my run
Too hard to watch the guage at WOT lol
Thom and Clevo120Y reacted to this -
No one makes them
Just need to keep looking for a good one, the xf ones fit too i think
-
Engine out, dont learn the hard way
It will always leak if you do it in the car
slydog reacted to this -
I agree Thom
Im using Mcdonald adjustable uppers and standard lower with rock hard bushes
Good enough for getting the pinion angle how i want it
-
Could be the alt
Get under bonnet and have a good listen while giving it a few revs at the carby

ill ask my mate where he got his for his roller ronny, what size do you need?
Cheers, 2.5" oval they call it which is actually 1 3/4" x 3"

Thats an engineer job, as long as all the other v8 gear and suspension goes on its not a prob to pass
Only catch is you need to pay the money to get it done...
Then your rego papers will have the v8 number recorded
Good idea to get it done cos if anyone with a car with major mods (and not passed) is in a prang (especially a big one with lawyers) insurance may be void
