i have a 97 hatchback with intake and catback apexi n1 exhaust. i just bought the holley complete annihilator ignition system and i have been told that it will add up to 30 hp? i want to find out if that is true or not. will it add hp and if it does how much will it add really?

 

You justed wasted money. The stock ignition was fine for the setup you listed.

Are you being serious (as in, you believe it) about the 30hp gain? (I hope not)

 

i dont even know about 10hp but my car ran much better! smoother idle and much smoother accelration. and i am using stock igntion coil! i will recomend the msd6a to everyone, only $135 and just use you stock igntion coil really easy to install. works good!!

 

mutiple spark ignitions are dope for any car cuz they insure more complete combustion, firing many times in the span that the stock ignition would fire once. themore modifcations you have, the more horsepwoer gain you wil see because as the cylinder environment becomes harder to ignite (cold air w/ n20, boost, or na high compression) this is where a multiple spark discharge ignition shines, making the most of the mixture and explosion in the cc.

another benefit to these ignitions is cd, "capacitive discharge" as opposed to inductive stock ignition. A conventional induction ignition creates a spark by applying 12v to the primary side of the coil. The coil steps the primary potential up to as much as 10,000 volts and delivers this high voltage to the spark plugs. However, this "step up" process is relatively slow compared to the mechanical capabilities of a modern engine--and as crank speed (rpm) increases, the secondary voltage declines dramatically. a cd igniton like the holley or crane or msd works this. Instead of applying 12 volts to the coil, a CD ignition increases the primary current by storing it in a kind of miniature battery called a capacitor. When this higher primary current is applied to the coil, the secondary voltage is dramatically increased. The MSD ca deliver i believe up to 55k volts, but im not sure. And with a properly designed coil, the step up process is very fast (compared to a conventional 12-volt induction). This assures a more consistent spark delivery across the plug gap, even at high *** rpm

 

does it increase hp? yes and no
basically if you have a very basic setup and you add a new ignition setup, you will see very little gains in hp
now, if you have crazy cams, c/r, etc...and have the stock ignition, then yes, adding a new ignition setup will give you back some of the hp that you lost with the stock setup

 

hey builthatch what did ur car run w/o the nos on the y7?

 

the y7 ran off bottle a best of 15.2 @ 90...it was not fast and was severly limited by the head, it really shined on nitrous sorta, when it was not blowin up. if i was n charge like i was n charge of my new y8 build, it would have made alot more power off juice. the built y8 is as fast as the y7 on juice. BUT ifyou need info on how to make a y7 fasti know all the trix now, i just was rather reserved and took a bak seat in that build, i let the shop do what they want and never was really satisfied wth the power output. i mean, itwas like 3 years ago almost, so i was young and did not know all that much. now i think i could make even a y7 fast. i mean the y7 made 40 more hp than what it makes stock to the wheels (88 vs 125 to the wheels) all motor but...i dunno...just its that not that fast compred to what i have now or what i think can be done to that engine with the right parts and headwork.

The Crane Cams Fireball ignitions are the ****. And they stand behind there product, as opposed to MSD.... Wait till your MSD gets a little wet... they won't do anything for you b/c it was due to an "installation error"

crane will ship you a replacement next day air.

 

the BEST place for your ignition box is in the passenger compartment... on the firewall out of the way. That is where my Crane will be in a short time. No chance of water/moisture damage there.

i have msd whit coil and no it will not give you hp over stock ignition i didint feel nothing at all!!
the real benifit is when i use NOS and turbo therefore you will see a huge difference in less timing retard so less detonation and maybe an increase in hp
