98 cobra semi new numbers

[lit]

well finally finished with most of the car. It's breaking up at 6k and just falls flat on it's face. Hopefully I'll have that fixed this week. Ordered new coil packs and will regap the plugs again. I need my 7k shifting to keep me in the power band. Not sure on the boost yet since it's just dies at 6k.

so at 6k on 18* of timing, t trim, 2.95 pulley, w/ aftercooler, 93 octane

557/493

ok, put on the coil packs (weapon x) and put in some TR6's gapped at .028 and it still breaks up. Any other ideas?

 

[avmech]

did you have it on the dyno when it breaks up? that should show you if its fuel or spark related. with all the mods, what is done to your fuel system? making that kind of power you would need bigger injectors,fuel rail,fuel lines, at least the twin pumps from a cobra and a BAP or a big ass pump.

I have enough fuel, I'm running the glennsperformance 1000 hp system.

I think you are going to need atleast a boost-a-spark or an ignition box.

Lot's of guys have had good luck with the BAS, but I never used it since I wanted to have a 2 step. AEM makes a box w/o a 2step that people seem to be having good luck with.

If you want a box with a 2step then MSD DIS4 or the new Accel DIS8 are your only options. I just switched over to the Accel unit and was having some issues. Accel just sent it back after 'fixing' the issue and I have yet to be out testing again.
