Yeah me too. Got to wait for my car to come back from Stealth before I can play!

Gavin, yes it's dead easy for woolly headed mitten wearers! Quite a few people find the engine is nicer with these coils. Idles better, better economy and better general drivability. I just like the fact the coils are cheap and easy to replace. £25 for a blown MSD coil once in a while, compared with £180+VAT for the VW one. It's a no brainer really.

Just need to wait for Tom's coil amplifier.

Yeah this is him ->

Thing is though, the 8870 is fed by the DIS 2 digital ignition box, so the modules themselves probably don't do the amplifying....they just hold the coils. Can get a bit pricey if you get the DIS 2 aswell :-)

I have emailed MSD to get an idea from them what current the amplifier needs to give and the best coil-on-time duration in microseconds.

Unfortunately I need to move on this and Tom isn't on here often enough to answer our queries.

Just a thought guys - as soon as this is worked out would it be possible to orgasnise a group buy. It would be nice to get some answers from MSD as they should know the best setup with their own products. It'd be great to have a group buy for the whole kit. Mainly as everything could be ordered in one go and save people chasing up different components. I reckon there could be a fair bit of interest too.

I think the main problem with the MSDs run from the VW amplifier is you can't adjust the coil on time. If it's too long for the MSD coils, they'll eventually burn out. The advantage of standalone ECUs is you can reduce the coil on time because with a stronger spark across a bigger gap, you can get away with a shorter spark duration.

But in terms of a GB, once Tom has signed off his amplifier, I'm sure he will then be in a position to sell complete MSD coilpack kits.

In the meantime, it's pretty easy to get the coils and HEI lead ends from Summit and the bracket from Gruvenparts and then add Tom's amp on when it's ready.
