V6 Dyno's

What I'm planning to do is to de-solder the pot from the board and re-connect it on a short flying lead so that I can adjust it with all the instruments in place

I've done this bob, with a nice small preset pot and a bit of heatshrink it looks pretty cool. Going to set mine using a oscilloscope.

Great stuff Jim, we will have to compare the resistances we come up with. I'm hopefully going to get mine done this weekend :)

yeah theres probably an NA/turbo difference as johnny says,or maybe not who knows..... ah well 750 rpm out,we are getting closer! at least it is now adjustable so getting it perfect will be easy.

Putting the potentiometer on extension leads is a great idea,why didnt i think of that....

For owner's cars having a straight conversion how about taking note of the exact rpm indicated at say 70 mph in 5th before the swap and then Paul can adjust the conversion to that after the swap.

Another dyno run is the only way to step forward.

It's not conclusive but it'd certainly help.

Went out today and did some adjusting of the potentiometer today...previously when the GE was in the car, the speed rpm ratio was the following checked by GPS:

70mph.....3250rpm
75mph.....3500rpm
80mph.....3750rpm
85mph.....4000rpm

To achieve this using Sengt's method I have had to set the potentiometer to 1.8K Ohms.

All is now good....and the rev limiter cuts in @ exactly 7000rpm

Hmmm, rev limiter should be 7,100rpm IIRC.

What's a hundred revs give or take lol....previously the needle was burying itself in the red before hitting the rev limit so it's close enough :)

Very true chief, was only pointing out what the cut actually is.

Good to know we have a new value for the potentiometer that's damn close.

This on N/A or Turbo clocks?

N/A clocks
