Most hp on stock ignition?
 

What's the most anyone has put down on the stock ignition? I've never had any problems with ignition break up so we're going to shoot for 22-25psi or more. Aug 7th is the date. Jeff48 will be helping out on the dyno so this should be interesting.

Only thing I have done is ngk 10 plugs.

Your going to have break up at that PSI range, I believe. Not sure what the highest HP number is but I bet you can hit 400 HP on the stock ignition.

I needed a larger leading coil and an amp in mine and I only run 18psi on pump gas. Plus my A/F ratios are very rich which makes it harder to burn.

Good Luck, don't blow your motor.

I've already ran 21psi with alcohol injection with no break up. I'll be running 114 to keep the detonation to a minimum.

Oh, alcohol, thats another story. I run 93 pump gas. Nevermind.

I don't run that anymore. I run 93 on the street. I'll be running 114 on the 7th.

didnt someone get about 550rwhp wiht stock ignition?

Who?

I have heard of 500 or more on the stock ign. before too. I just forget who and the exact HP number. Didn't want to step too far out on that limb.

right now i cant think of who it is for the life of me but its a fairly popular guy on this board. crap, some one should know it is... where are all the other oldtimers on this board???

what's the car being used for? Are you always gonig to be running 114 octane or are you just shooting for a big number?

Tim

straight line......i don't have a problem with running big $$ fuel.

Anyone know who has the most hp on the stock ignition?

Ive done 470 to the wheels at 20 psi on stock ignition and ngk 10.5 race plugs.

This is the type of info I like. Why did you stop at 470? Break up or just happy with that number?

I was there on that dyno day. It was on KDR's dyno, coupla years ago. As I recall, Mr. Ihor Huk wanted to go for 500, but his injectors were maxxed out. The ignition was fine. Dave doesnt like to push cars too much on the dyno. Ihor was running a gt35/40, the car would spin the tires at highway speeds......

gonna try for 22+ psi on sat....on the dizzno

Jeez Eric, I thought you were already making about a bazillion horsepower and your car only weighs 800 lbs. with you in it, so why are you worried about how much power you can make with the stock ignition? Isn't that T-51R Kai the next best thing to magic?

actually the new weight is 3375 and I've went back to my stock irs. I've since ditched the turbo and went with a eaton supercharger. Hopefully we'll be able to see a 25hp increase with enough boost.

got tuned for 18psi on 93 octane..... tosses 114 in with race plugs for the dyno and on the second run my manual boost controller popped off causing me to boost 23psi then my turbo sucked in my boost controller...... new wheel will be here tommorow......

until next time..

I took some automotive classes at school and my elc. teacher said that all that ign. stuff doesnt do much. the way he explained it was you have a 12 volt system runnig though the car how are you going to get more spark with the same amount of power? its like getting more horse power without more fuel or air. he is an old mussle car guy and he teaches auto elc. so i trust what he said was true. i mean it makes sence

no it doesn't.

To a point, you'll make more power with less fuel, FYI.

And you can increase voltage seen at the spark plugs with a higher powered ignition. This will make the spark less suseptable to being "blown out" by the high combustion chamber pressures.

Put a HKS twin power/AEM on a stock car and the gains will be negligible. Put it on a car running 25psi+/500hp with ignition breakup, and you will notice gains.
