spitfire multispark
went to a kit car show at detling in kent on saturday and bought a spitfire multispark lead. it's basically a lead that replaces the existing one from the coil to the distributor which instead of providing one spark to each of the plugs, has a small device with ceramic discs inline which turns 1 pulse into 5.
i fitted it to my mac1 (www.mac1motorsports.co.uk) on saturday afternoon and couldn't believe the difference in acceleration. has anyone else used one of these on a longer term basis?
my neighbour has a tiger super six in bits at the moment and after driving my little car, he can't wait to get back on the road and give it a try!

thought there had to be a downside. i don;t tend to do that many miles anyway so will accept the cost of replacing the plugs more frequently in return for the additional power!

In tuning circles, things like this are usually dismissed.
You only have one mixture, and that mixture burns from one spark - multi sparks dont do anything really as you cant make the mixture burn 5 times as quickly.
Usually an expensive placebo effect, just the same as those multi electrode spark plugs.

with regards to plug wear, single elecrode plugs last for only a finite number of sparks. You need to divide at number by five, or probably more (because your plug is now heating up five times between each cooling bath of fuel) to get an idea of how short a time they will last.
PS: despite all the b0ll0cks talked by dubious tuners about multi electrode plugs giving you better performance, all they actually do is what they were designed to do, which is allow manufacturers to increase service intervals.
