Keith, are you talking about the extension pictured in the red square?

[911st]

That looks like it.

[WERK I]

Its not really needed unless Steve is planning on using the air pump drive. This is discussed earlier in the thread. The camshaft will still need to be modified, tapped, to support mounting of the extension to the cam.
The extension is mentioned in Bruce Anderson's 911 Performance Handbook, Third Edition. Its a Porsche Racing Part Number: 911.105.171.02

I thought he wanted it for a turbo savaging pump.

[sjf911]

I would need to add it to run the Clewett combined scavenge pump and cam sensor or to retrofit an air pump drive to make my own cam sensor. I would like to convert to a mechanical scavenge pump at some point to get rid of the Tilton. I already have a stock 930 pump set aside but I currently have the Clewett cam sensor installed on my driver side cam am awaiting MS3 for sequential injection.

LOL, still available and only $440 according to PP. I'll have to think of something else.

ROTFLMAO!! And I thought $200 was laughable!


Steve,
Why do you think you need the camshaft drive extension?

[911st]

I did this years ago and it was about $150. Web Cam I think makes there own and included the extension in the price from what I recall.

The factory piece for an MFI conversion is to expensive to use and may not be the same as the 930 uses for its oil pump.

A lot of guys buy SC or C2 factory cams and have this extension added. Just check with any good Porsche cam grinder and they will probably be able to convert your cam for a reasonable cost.

[sjf911]

Thanks for the info. It is a future project. I will stick with the Tilton for now and await MS3 for sequential injection and direct coil control. After MS3, when circumstances allow, I can consider my options for converting to mechanical scavenge but retaining cam sync.

[911st]

OK,

I called Web Cams. Cost is $165 to convert an SC cam to drive a 930 oil pump. No factory spacer needs to be purchased.

Great info, thank you.

Currently I have an Accel dual sync distributor (includes cam and crank...), but am having a hard time figuring out how to configure it within the Haltech and neither Haltech or Accel want to give me a solid answer about how to set it up. So now I need to set up a hall effect crank signal and an hall effect cam trigger. The crank trigger I pretty much got figured out- My real question is:
What are the distributorless guys running for a cam sync/signal? I have already seen the clewett offerings and neither are very viable for me (although they are cool...)

Hello All, i came accross this and honestly wondered about your problems. First let me say that its possible you have probably not called the Haltech US office, if you have, you probably may have not talked to me. I have actually done a few Porsches in my time and i must say i love them to death, especially the old ones.

Having said this, i am here to answer your questions about triggers. The simple answer is that virtually any option is possible, its just a matter of prioritizing your needs. If you want to maintain originality, sticking with the distributor triggers is fine, if you want all out performance, a crank+cam setup is needed. We have single channel and dual channel hall sensors in stock that can let you do just that, we dont sell trigger wheels but we do sell the rare earth magnets that can let you build a custom flying magnet trigger, either inside the distributor (as ive seen some pics on this thread, or on the crank pulley.

Motronic, missing tooth, trigger wheels work very well, especially the 36-1 using a hall effect sensor, this only provides for half cycle, wasted spark/semi sequential, operation, but if you modify your 6 tooth/slot wheel inside the dissy leaving only just one tooth, this can double as your sync/cam sensor with no problems.

Haltechs can read Hall or Reluctor style setups and with the new Platinum ECUs you can properly configure your reluctor triggers to permit perfect triggering all the time using the trigger/home voltage threshold tables, filter levels and proper wiring and configuration of the trigger setup page.

I have never met an engine that could not be run given the appropriate trigger installation.

If you have any questions, please feel free to call me at the US office, just ask for Claudio.

Have a good one boys. I dont know if i will monitor this forum much, but my contact info is bellow.

Just got off the phone with Claudio^^^^- It looks like I am going to keep the accel distributor as at can work with the computer. It turns out that I was not contacting Haltech direct, I was contacting dealers and they were the ones who didnt want to help me with my problem. Ten minutes on the phone with Claudio took care of all my concerns with the distributor and more. Thank you Claudio!!!

Bravo I am glad at least one of the companies involved jumped up to the plate.

[drmatera]

thats a great resource....

Thanks for coming on here Claudio

[HaltechClaudio]

You're all welcomed guys! I can honestly tell you that anything is possible when using these units, pretty much all possible angles can be covered.

Let me give you a quick run down, you can run the stock dissy from an old air cooledmotor, you can use the 60-2 trigger sometimes found on a few more modern years, you can build your own custom setup as ive described in the previous post, you can customize your existing hardware, or add some more.

These cars are loads of fun, power potential from what ive seen is incredible, all it takes is a little information, which we can provide!

Here are the sensors we have, this is the "GT101", its a single channel hall effect sensor that is similar to some bosch units as far as dimensions and installation style.



Here are the rest, from left to right, "Red Hall Sensor", "S4 (dual channel)", "S3 (dual channel)". The S3 and S4 are the ones that use "rare earth magnets".



And of course, Haltechs are perfectly capable of reading of most reluctor style sensors. All it takes is a little patience and the right settings.

[gsmith660]

Hope you got permission to sell your wares though, Wayne is a little particular about that.

Seems to be a problem as of late. Everyone with a buisness license are becomming dealers now but don't know jack **** about providing 'support' for the product. Anyway I contacted Claudio after stumbling on this thread so you're in good hands now.
Another option for you would be to just use the ACCel distributor for the cam/sync and use a Clewett crank trigger kit.
With the above setup you got many combinations available for both ignition and injection setup. You can run full sequential injection with a direct fire coil on plug or a wasted spark setup.

So for a Carrera conversion we can use the Motronics Flywheel sensor and can we put something in the stock EFI dist to indicate motor/cam phasing?
