RAZOR ,,caspers volt booster

[SNOWBIRD]

JULIO,,will caspers volt booster affect how your kit works.....it only supplys voltage gain to ignition and fuel system....

 

[1QuickGN]

You don't need a volt booster with a PAC kit. Or a second fuel pump just a good tune and you should see big gains with your car. I know I did.

 

[SNOWBIRD]

2GN what fuel pump are you running...what i meant,will a caspers vb cause the alky kit to pump to much alky and cause a rich condition

 

[1QuickGN]

I had ATR 2 pumps with a volt booster. With both in use I went real rich. Unhooked one pump and the volt booster and went faster than the car had gone before. Best bang for the buck in my book.

 

[pacecarta]

im still tuning on my 86 but i run 2- 340s in the tank and the reds vbooster so far i would say i am not having any real issues , i can control my fueling in the chipand if need be can go WB controlled so going rich isnt something thats going to happen


My VB kicks on at 10psi and i use the voltage to know when im above that and when the booster is active the voltage is dead stable with no fluctuations which makes tuning that much easier

i dont beleive mellissas car runs a VB and that went 10.10 on a single pump

anything added becomes something else that needs to be tuned around and julio has advised in the past to not run one with alky since it does increase the pump output and his advice to KISS applies here as well

 

[Grumpy]

No Melissa doesn't run one .. single 340 pump like pacecarta said ... KISS

Results will vary. on my car i was using atr double pumper and alky car ran very clean.
On Julio's car the volt booster caused a rich condition and was then removed.

 

[SNOWBIRD]

MR.GRUMP...have you done anything to the stock fuel line,are you running twin nozzles on the methanol.....I will get to the point ,what is your secret:wink: I know melissa only weighs 20 lbs:

 

[PhilM]

If you're fuel lines are not restrictive and the booster isn't actually boosting the V+ supply for the alky pump then there should be no reason it would cause a rich condition - if it's getting rich because of the booster, the return is likely too small and simply put the engine doesn't even need it then. I have 2 pumps, one enabled via. DFI at appx 8psi and there is NO change in FP from the 2nd pump turning on. This is with a 3/8" return.

stock lines and dual nozzles big secret is her right foot :biggrin:

The volt booster I used is the old style Red's. When it activated it raised voltage on the entire car. Doing so it made the alky pump also more aggressive cuasing a dip in air fuel ratio. Looking at wide band data confirmed what I was feeling.

You look at data, and make your decisions. Cant make decisions... without data.

My car runs on a single 340. Been over 132 MPH quite a few times with no sign of fuel pressure dropping. I think it will go easy 136-138 on a single given enough alky.

Can it hurt to have a double pumper.. nope. Its only money misdirected if not needed.

stock lines and dual nozzles big secret is her right foot :biggrin:

Dan, can you put up a picture of the dual nozzles or explain the plumbing. Do you simply have a "y" connector?

 

[pacecarta]

mine is a alkycontrol dual nozzle ,
T fitiing off the supply line to two short hoses to the two nozzles mounted vertical and opposing each other aprox 6-8" from the TB blade.
i wrapped mine in conduit but the lines are all braided steel jacketed and meth compatible
make a call to julio he can supply what you need

A volt booster increases voltage.
More voltage = faster pump speed.
Faster pump speed = more alky/fuel.
more alky/fuel = rich condition.

Yes or No??

just a T fitting .. give Julio a call and he can set you up

NO!

From the boosters i've installed (MSD, etc..) they only boost the fuel pump supply... I have no freaking clue why you'd want to boost the entire battery supply, not to mention the amperage rating $$$ for the converted unless it is some cheapo passive deal. The MSD boxes can generate over 20V, which is fine for the FP but I would get very wary about driving all of the car electronics at 20V... Hell, my alky controller has transient suppression at 18V to keep the line clean and the unit safe!!!

EDIT: just did some research... it seems the cheapie V boosters only increase the main supply by a few volts. You want a real booster, spend the 200 bux and get the MSD unit

For many many years the buick vendors were selling a "volt booster".
This was hooked to the back of the alt, and to a hobbs switch.
it would "full field" the alternator above 10psi or so. 14.4 volts or 14.8 on the whole system.this would speed any pump up a little.
thus ..... the rich condition...

 

[S2V6RACER]

I see 15.0 to 15.1 V consistently with the Reds volt booster.

 

[XxDarkSidexX]

well even if the volts booster increases voltage to the whole system, thus increasing pump speed, thus making a rich condition. This increase should, and would still always occur consistantly. So you would see it in your tune, when dialing in the car for WOT runs. But could cause funny idel tunning conditions i dont know, havn't had a amp or charge problem yet. Thus as someone mentioned earlier, through tunning it one could make changes based off this, adding it to the tuning map of their cars. but that just offthe top of my head. F.A.S.T. is the way to go for all the monitoring bussiness, it doesn't get anybetter......... Well it could, F.A.S.T. could have a hot chicks in panties as their DVD instructor instead of a retarded spark plug and some old men:smile: :smile: :smile: :smile: "F.A.S.T.DVD Xrated BABY!" haha. Watch how many people would 1.) Would instantly, i mean instanly go and buy a F.A.S.T. system 2.) THEN actually pay attention and learn to become F.A.S.T. experts and thus BECOME better racers and tunners. I should freaking open a private college, wouldn't you pay attention if your teacher was hot? :tongue:

Im excited to see what people have to say. about this VOLT BOOSTER subject. I just bought a volt booster myself, but am thinking of just upgrading my alternator so I could controll the voltage and not have to worry about amprage draw. Don WANG thanks again, as usal I WILL OBY DA DON and probably end up just spending the money and getting the powermaster alty, those are really nice units. Or go the cheap upgrade rought and get the lt1 alty which still has a 140amp to it. Well see what the old budget allows I'd like to also thank turbo39151 for giving everyone a good 140amp for $ solution as well! I still think the volts booster is good choice for most modified street cars, but not all "street cars" are the same, and not all cars draw the same amount of required amps/volts so, to his each own!

We told ya what happens in the posts above. Its not needed. And will hamper performance. Put your car on the track and let me know what happens.

Thats the ultimate truth.
