Engine and Transmission / Re: 1.6 8v G65 ...

The 1,6L heads flow better than the G40 heads at high lift (over 9 mm), but remember that only the ports on the AEA/AEE is similar to the G40 head. The ABU have round ports

It would be hard to hit 200 with a G40 charger, a G45 or G60 would be better suited

yes it's normal for that reading to be constantly moving.

Engine and Transmission / Re: Boost issue???

doesn't sound far off to me too for a 1341 with a cam (although you don't say what cam, I'm assuming something like a 252/276) on a 65mm pulley.  There'll always be a bit of variance between different boost gauges though, they're not mega accurate.  If you've got another spare gauge around you could try it and see if it's any different.

Over bore + longer duration cam will both reduce back up of pressure  - it just means the engine is using more of the charge than a standard lump would.

Engine and Transmission / Boost issue???
« Last post by tomsuch on July 01, 2018, 09:32:35 pm »
Hi guys.
Just bought my 3rd G40 a week ago. My previous 2 had toothies and stage 4 charger plus a few little other bits. They both seemed to boost at around 15psi 1bar. My new one is also on toothies, stage 4, cam, 1341cc fmic and a few other bits but it seems to only boost at 10psi, doesn’t matter if I’m wot at 2000rpm or 7800rpm it’s still at 10psi. Could this be a faulty boost gauge? It seems to go very well.
It’s plumbed into the vacuum line from the fuel pressure regulator so the correct place. The pipe is fairly small though, could that be the issue?
What’s your thoughts?
Cheers
Tom

Electrical / Re: CO sensor part code?

FLIPPING HECK, CUPID STUNT... I don't need a sensor is the long-and short of it.. But it was "interesting"...
THE SENSOR IS OK!!! It's the (out of) fuelling!

I went out expecting to be taking the sensor off.... I wired in the scope to the sensor-output and initially I got the nice saw-wave I was expecting... Then there was the odd *spike*… I went to get the camera but then more and more spikes.... Then the engine cut out, !!! *AND* !!! the petrol pump went mad noise-wise when it was called to pump....

Maybe the 1/5th of a 5litre can that I put in last week has been used/is vapour...! No wonder it wouldn't rev, and constant bleeding of the injectors rail bubbles, probably was air out the tank... 4 foot snakes..

I've lost the most basic diagnostics skills when it comes to cars not driving for so long.. The carburetted Morris-Mini with-points will probably be my limit as an automotive engineer, it's a good job I don't do cars for a living! I'm a programmer, I can't help staying clean and knowing what I'm doing in reality!... :-P :-D (if you ever saw the winter-big-wheen in hyde park I did the lights!)

More my kind of project now I might look at when I get back from London:
I've been playing with PIC's a lot,
I can get a CanBus devkit to look at the ECU output, I bet MicroChip'll send me one if I put more videos of it on my tube-channel again.. I've got loads of kit like that!
I bet I could make one chip drive gauges/green/red-lights for everything important off the ECU and/or even have a little OLED display..

But it's gotta ask the question "is there petrol in the tank Neal?"
Cheers for the info, it's good to check first though init!!!!
Thanks! :-) NEAL

Cool, for that price I'll change it again in 10 years...
Cool, appreciate the easiness... You are a star
