Depending on which system you get, They sometime do diff. things. MSD 5 
and 6 series i believe produce multiple sparks only until 2 or 3k rpm, 
and then return to just one spark. Jacobs on the other hand, senses each 
cyl. and adjusts for load and mixture and produces one hell of a fat blue 
spark! On my race car (VW) I ran msd and a red coil for years with great 
luck. I installed the entire Jacobs system in front of the MSD, which is 
now just a back-up, and i actually noticed better starts and better 
performance, although I think thats due in part to allowing me to run a 
richer mixture without fouling plugs. MSD is nice and cheap, and Jacobs 
is nice and expensive. Jacobs is a bit more street oriented and I think 
their R&D is far more superior to MSD. I'd be more inclined to call 
Jacobs first, because MSD rather talk with american car 1/4 mile car owners.
Techtonics, with whom I do business, and are a great bunch of guys, says 
leave the bosch alone! I agree with them to an extent. Bosch makes a 
reliable system. Techt. claims that Bosch is the best you can get, they 
run it on their alcohol dragster! I disagree with them on that point. 
Maybe alcohol doesn't need allot of spark, i don't know for sure. 

If you call Jacobs, ask for Anita. She was telling me about the R&D they 
were doing on Bosch replacement parts and computer for German cars. See 
if they came up with anything.
