ordered a set of the solid wire connectors. Summit sent the wrong thing. GRRR!!!!
Just call GMS direct - they will take care of you - ask for Chris

Not very good without them being a vendor here or a vendor that sells the stuff doing it .Whats chances of a group buy or forum discount?

I know that but some of our vendors carry the GMS line so I was asking if JR would cut them some slack so they could do something for us.Not very good without them being a vendor here or a vendor that sells the stuff doing it .
How about a group buy on the wire upgrade?

That would be nice.I know that but some of our vendors carry the GMS line so I was asking if JR would cut them some slack so they could do something for us.

whats going on??Speaking of.....he is over installing the Silent Scope fan shroud, stop on by!
So...did you use the coils or just the wire assys???So I ordered the wire kit. The factory wires are a couple of springs with a slug of metal inside. The Granatelli are stainless cable with crimped on connectors. The kit comes with new boots.
Somehow this got past qc. It still works fine.
I put them in. I don't believe I'm writing this but they made a difference in driveability. There was a little stumble when warmed up that's gone. There was alot bigger stumble when it wasn't all the way warmed up thats alot better. I didn't change plug gap, just the wires. Hmmm....
Thanks for the info!! What part ## cops did you get?I posted this in another thread, but thought it would be a nice recap here of my experience with Granatelli (GMS) Coil on Plugs....
So, here is a summary of this year's racing data from my timeslips with the only power variables being spark plug gap and coils...
- .045 gap and stock 20K volt coils. Average trap speeds of 112 to 113 mph.
- .028 gap and stock 20K volt coils. Average trap speeds of 107 to 109 mph. So, with stock coils, just gapping down from .045 to .028 (absolutely no other changes) cost me 4-5 mph through the traps (ouch!).
- .028 gap and GMS 42K volt coils. Average trap speeds of 111 to 112 mph. The GMS coils got back 3-4 mph of the loss from the tighter gap (nice!).
- .045 gap and GMS 42K volt coils. Average trap speeds of 113.5 to 114 mph. Widening the gap netted me another 2 mph roughly.
In summary, I am 100% certain that a .045 gap with aftermarket coils is worth about 20-30 rwhp (maybe more) in my car vs .028 gap with stock coils. Looking at my recap above, we're talking about a 5-6 mph improvement in trap speeds between those 2 scenarios. That's very significant no matter how you disect it. And for those who hate GMS for whatever reason, please note that my car went faster through the traps with the GMS coils regardless of which gap you compare. As always, your results may vary, but I feel the GMS coils were money very well spent ($249).
