Xflow distributor removal

[tikijose]

Hey, does anyone know if the Lucas distributor on a crossflow can be removed without removing the intake manifold? I have twin DCOE40s.

 

I'm wondering if I need to add an intake gasket to my Pegasus order.

 

Thanks!

Yes it can. Take the leads out first.

Thanks for the help. Hopefully, this will be a simple upgrade.

The distributor and coil upgrade were very successful. My suspicions were confirmed and the old Lucas coil just wasn't advancing properly. The car is running really well. The problem now is that the tach is really flaky. It bounces around and seems to bounce more as the RPMs increase. I ended up disconnecting the tach so I wouldn't damage it.

 

The new coil is a Pertronix Flamethrower II (0.6ohm primary). Is the coil overpowering the tach? Has anyone seen this? Is there a solution out there?

I had the same Petronix set up on my X-Flow and the tach never worked right, especially under hard acceleration to redline-constant tach needle bouncing.

Thanks, Good to know it's not just me then. May have to experiment with some resistors on the tach input. I have a tech request in to Pertronix. Maybe they've seen this before.

 

I can't give up the new ignition though. It's made such a difference in the car. Either my old coil was giving out, or the advance curve was way off. It's so much better now.

Yes, stick w/Petronix. The bouncing tach has been the subject of posts here in the past and, as I recall, replacement with something more high quality than the standard Caterham tach is the preferred solution.

 

Ditto the laughable oil pressure guage that Caterham supplied on its X-Flow cars..

Thanks for the advice. Dave Bean recommended a Smith's gauge for the tach. It's a bit pricey, but it works with the Pertronics and it's British. I keep hearing everyone say the oil pressure gauge is an issue. Currently, it's my most reliable gauge. Fuel sender unit is dying and doesn't read above 1/4 tank, temperature sender is dead with a new one on the way, tach is flaky because of the ignition, and the speedometer is way out of calibration. It's so good to be back in a British car.
