Alternator yes or no?

[HEAVY DUTY]

I like them. Dont have to ever put a charger on. If you kill the motor late in a race, it fires right back up without dragging.I use a small 1 wire unit that weighs about 7 lbs. Sometimes if I am not running it and forget to put the charger on with a yellow top Optima mounted in the rear next to the fuel cell ( with good Quickcar battery cable ) it doesnt crank over very good and I worry about not starting if I kill the motor. Just speaking from experience right or wrong.

i figure it like this,..we try to get all the air an all the fuel into the combustion chamber as we can,..so we want as strong a spark as we can get to ignite as much as possible to achieve the fastest, best possible burn of the air/fuel charge,..an that requires proper voltage.... now if you can maintain proper voltage without a alternator,..kudo's for you! if not,be sure you get right pulleys an good mounts,..took the alt off my car,belts coming off became a issue,...but if i find im losing to much voltage ill be putting it back on...

well maybe that his problem. he run a 2 barrel carb not much motor and not that much fuel. but there more to gain than there is to loose by running one.i build 400+ transmissions a year at my shop do not advertize all my work is by word off mouth so one would think i know that i am doing and they would be right. but i still make phone calls and have to go to the books from time to time.point is we are always learning when you think there is not a better way to do it and refuse to try something that may be better than you have lost the game before you get to play.

BRAD you are better with your words than i am and that is what i was saying. we use FRANKIE GOODS DYNO we run our alt off the back to keep it out of the way. still run a HEI very modified one that holds the record on the dyno for torque in a crate. frannkie is still trying to get me to go to MSD. but was sold on the alt when he showed me what we was loosing and as you know we try to keep every thing we can get with a crate. so do you think HEI pull more juice i would not think so but let my know if you can.

[twisterf5]

never said what i had!!! but if you must know it is a MSD HEI you are the one that said HEI used more. and like i said i hold the record on the dyno with it. but that is in a crate i seen no need for a box with a crate motor and still feel that way. but like BRAD said dropped to 10.8 with a charger on it now what if you are not running an alt and you forgot to charge the battery and it was a long race how far did it drop now. you just mad because you are wrong.the thing with you is that you think you are never wrong even when it is infront of you. now i have engines from 4 bangers to 400 + super engine crate is on HEI steel head and super are on a box and both turn over 8000 so i will just keep our alt and you will find something wrong with what some one is doing because that is all you know how to do at this point in your life.

is the ONLY thing we have used from 2001 to now and we still have the original one and it still works great. its k.i.s.s. and clean looking.

exactly!! closed eyes are as good as blind eyes...

Ego, bahaha. funny stuff right there, I dont car if you call me a liar about having a sponsor for six years, your irrelevant to me. Now clearly I am important to you!

Thanks for being a fan!

If I am so irrelevant to you why was I brought into this? You think that is me? Too Funny! If that is me I will GLADLY pay for your entire year of racing in any class you choose for the next 10 years. You must be full of yourself when someone thinks differently and you try to say that it is only one person, do you really think that you are so correct that there is only one person that knows differently? Funny Stuff right there.

This is really entertaining on a cold Jan. evening. Oh wait, i almost forgot the subject. I charge my battery betweet the heats and mains and it works for me. JMO.

[dirty white boy]

What dont I understand? I can clearly see now that f5, dirty white boy, and you. Are all 3 the same user. All 3 are blind to the FACT that Msd on their own site says what voltage is needed and there is no way there are 3 different people stupid enough to keep saying the same thing over and over and backing each other all the while all three of them keep making statements attacking me clearly with a agenda.


Like I said its clear you 3 have a agenda, pherhaps we found ANOTHER one of dyno mans names since he has had the same agenda.

As for your question, yes I can use the chassis dyno any time I want. They are a sponsor of mine and have been for over 6 years now.

wrong on so many levels...mr clew lives bout 2 hours west of me,...idk who snowapb is but it sure ant me,but he sure seems to have your number an calling you out on your communication skills,....T5 runs my home track some an we've actually meet a time or 3,...i admit i dont know half what ether of yall 3 do bout racing,..thats why im on here,TO LEARN!!! use to learn a lot on here,..but with jeff contradicting an harassing any an every body that dont worship his knowledge,..this forum has become pretty much useless,..just drop by now to see what crazy ramblings dynodummy been posting,..this board could be so full of wisdom an knowledge if peoples ego's were in check...

[twisterf5]

sorry guys had to work. got to pay for these race parts. but been some fun reading.

[powerball]

No instant reply from " rock star driver"?????

He must be hotlappin on one of the Dynos in his fleet......

The sound of his silence is wonderfully deafening! Hope it wasn't the new kid that got him to shut up for a while......He would never live down getting outwitted by a newbie,low Iq,new screen namer would he?

Please tell me he wouldn't just give up like that?

And for the record again, I have seen the f 5 run that twister chassis modified in and around the Carolina's from time to time and the car was pretty good when I saw it....

Rock star driver......don't discount what you don't understand....leads to a very narrow mind.

i dont care who you are THATS FUNNY ZHIT RIGHT THERE !!!!!!!

i think HIS screen name says it all! street stock driver lol what a joke!

oh ya i like to run alternators too

If you do a search one of the mags did a test on a low battery with an MSD and found that below XX voltage the MSD was not reliable. Also MSD shows on there web site and in the tech manuals 11-18 volts as operating voltage. That is voltage under load, If you are shutting the car off and getting out and checking the battery then you are not getting a true battery test.

Also something to think about, at what point does the voltage to the coil and tach start making the tach unreliable?

dont know were i read it but it said you have to be above 13.5 to keep it at optimal working volts. and would think that it take less to run a HEI. the reason they stay away from HEI is because they brake up at higher RPM'S the way i see it it takes more power to make more spark so would think that a box type system would take more power to run it.

Battery and Charging System

You can have the most powerful ignition available and tuned to perfection, but without a battery to fire things up, you’ll be going no where. The battery is the main source of power for a performance ignition system, and you need to be sure that it’s capable of having the juice you need get the engine fired up. Not to mention to supply the ignition with current and voltage created by the alternator.

There’s more relying on the battery than just the ignition system. The starter is also pulling huge amounts of current to crank over your engine. Adding compression and big strokes adds to this demand as well. Also, any other electrical devices such as fans, pumps, motors, and even fuel injection controls all tap into the battery for voltage.

When looking for a batter, certainly look at the cold cranking amps (CCA) racing. Also look at the cycling, or recovery capabilities of the battery.

Alternators are used on all street cars and even on the majority of race engines (except purpose built drag cars for the most part). The alternator is responsible for producing the electricity that a car draws from the battery while it is running. The alternator generates an alternating current (AC) when it is turned by a belt and pulley system connected to the crankshaft. Inside the alternator, a rotor spins to create a magnetic field. This field is induced into the windings of a stator (around the rotor), and eventually makes its way to the battery as direct current (DC).

If you run a battery without a charging system, it is important that it’s fully charged at the beginning of the race so it has the capacity to power all of your car’s electrical needs through the finish line.

this is off MSD side so not running one will work that all depending on how long you race how much engine you are firing up and what you are powering. but it is clear they recommend running an alt.
