built h22 turbo, running 880cc's a aeromotive a1000, aem ems..... would a 7al be overkill or do i need it? i dont wanna get somethin too over the top.... im hoping to be in the 550-650 hp range, ive seen it with VERY similar set ups.... just lookin for some info...

 

oh yea small NOS Shot might be in the plans too... nothin crazy 50/75?

 

Either will work fine

7al's are not that much more though and have a tad more features.

 

6al, stock coil, stock plug wires made more than 600hp with no problems.

Show off.

 

If you plan on doing alot of street driving dont get the 7 series,not really meant for the street.They run too hot under regular stop and go driving and may burn itself out.MSD doesnt recommend it either.

btw..get the digital series of whatever one you go with

 

very helpful info D-man.... if what u say is correct looks like ill be goin with a 6al... i plan on drivin it on the street a few days a week i think not everyday but alil more than a weekend warrior

 

You should go with the digital-6,its alot better than the old 6al.

yup exactly what he said i got a couple fried boxes i went through threw the years 7al on street is a no.no

p.s try bigger injectors

 

u think bigger than 880cc even with the aeromotive pump?

on the digi 6 ! thanks Dman

 

your pushing it with 650 hp if you drive the car at nite with lites on and drawing lots of power from the pump that aeromotive draws a lot of amps,atleast thats what i noticed with my pump and 1000cc injectors

 

MSD 7AL-3 all the way

 

ok lets refresh.... i will be driving the car at night alot . . . im gonna try not to drive it any long distances.. ( over an hour? ) i do however have a small NRG_cell battery (heel-toe) i wont have any crazy sound system.. a deck and 2 door speakers.. thats it... i was also considering hooking the alternator to a switch, someone gave me the idea and it sounded pretty good but i havent looked into it... (shut the alt off during a quick drag, then switching it back on?) . .

 

turning alt off hmmm, i know that 7a needs constant 14 volts or it dont work......i said the same thing bout the 7al "ill only be driving short distance no wippers no system blah blah " long story short i spent a lot of money on 7a"s and towing

 

No alt and a TurboStart 16V battery? j/k, but that is the only way I would run without an alternator, and never on the street.

 

alt would only be off for under a minute, like i said just to get every ounce of power for the drag then switch it back on. . . idk just somethin someone was tellin me and they made it sound like id get decent power if the motor didnt need to power the alt

 

extremmly minimal i had acouple full race mustangs back in the day and had no alt. at all, strick track and one pass street runs and that was such a pain in the @$$ ya got to stay by the car each round with a battery charger so no one steals it and if the 7a didnt have full power .....nada car ran like ****

 

yea i doubt ill do that , but ill end up goin with the 6 series... and if i have EMS that will control 2step so do i even need the digital? ill prolly get the digi anyway. .
