Hello.
i just got my dual plug Viperhead to use on my 91 C-Spec.
what im wondering is :

1. the instructions call for 2 shims - either .008 and .004 or two .008 ? which combo are you guys running ? i will be running a Cline \ MP2 \ CP30.

2. which glow plug combo are you guys running ? will running two OS 8's do the job or am i better with one OS8 and one A5 like the manual recommends?

thanks.

I'm running one .008 shim and two Enya #3s, seems to work great.

I followed the directions for the outside temp. I cant remember the shim thickness. If I recall corectly it was the .008 and the .004 for above 70 degrees. I am presently running an OS8 and an A5 and wouldn't say there is any problems with it however I have read that two 8's will work fine also. I don't know what the benifits would be. I think next time I have the fan shroud off I will pull the A5 and see what the diffrence is. Any particular reason you went to the dual plug head on the Cspec? I am in the middle of building a Vigor CS with the Cspec in it. I left the single plug hyper head.

The dual plug is designed to add power among other features, thats my main reason, i also went for the Cline regulator, as they say this combination is a winner ! certainly not cheap, but a winner !
when i get the chance to try it i will post my results.

in the mean while, any other setups from people ?

What would the benefit be of using both #8 plugs rather than a #8 and A5?

There isn't much of a difference in running different plugs. You can run two OS-8s, and 8&5, 8&4 etc.... any combo will work...

Installation question

I just purchased the Viperhead for the C-spec. When I install it, do I have to use the original head gasked and the provided shim, or just the shim? Don't want to screw it up, so I thought I would ask.

Thanks,
Angelo

Use the original and one shim. 8+4 for higher nitro. Lower nitro may work with one shim.
