With Nitrous he is putting down 529 hp and 615 Ft/torque but the car is not providing enough spark right near 5500 RPM's...it was suggested to upgrade the ignition system...I need help with what to go with...any ideads???

I think most people would recommend an aftermarket ignition box when using a power adder, including nitrous.

I don't have a power adder, but have been running a MSD 6A for a few years without any problem.

Finding a place to put it is the hardest part. Buy a MSD plug-in harness so you won't have to cut any wires and you can go back to stock in a matter of minutes. Pretty much plug and play.

FYI: I have 30lb injectors and my stroker is NA and not putting out anywhere near the hp of your friends. I am at the upper limit of the 30 pounders. I think her should do a little math and upgrade the injectors and fuel pump system before he actually lights a real fuse under it or a lean condition will result.

Yeah we were all suprised. Could not believe it and what is even more amazing is that the computer has never been reprogrammed

a friend of mine is selling a Crane Hi6TRC ignition box which is perfect for ur buddy's nitrous useage ..

it was originally mine (ran 100 shot on it many times) then i upgraded my ignition to a digital 6 .. and sold my crane box to him (he has a 2nd gen) and it doesnt work on his car and he's trying to sell it

he'll tkae $190 for the Crane Hi6 and the TRC timing control box ($315 new from summit) .. if interested email me

its a VERY good box btw.. i only upgraded from it because i wanted a 2 step limiter
