I have been seeing my voltage at higher rpm's drop down to the mid to high 11's. I know thats not what the actual voltage the battery is at but after it goes through everything and reaches the computer. I have seen many threads on this and no one i have seen had and answer. They tried replacing the battery, alternator, grounds, power cables and more and ended up with only a slight improvement if any. This product promises a voltage boost at 70% throttle. Summit has it for $79 so what do you think or if you have tried one how good was it? It sounds like the answer to our problem but i have seen many promises that are pipe dreams. It appears to be all plug and play so install would be easy.

Caspers Electronics V-Plus gives you hotter spark and increased fuel flow when you need it most.
Your alternator is designed to put out a specific voltage, generally 13.8 V. The only problem is that when there is a greater demand on the electrical system, such as a wide-open throttle blast, the alternator falls a little short. The V-Plus boosters are designed to overcome voltage taper at wide-open throttle by stepping up the alternator voltage by 2.2 V at 70 percent throttle. This provides more power to your fuel pump and ignition system. These V-Plus voltage boosters plug in, with no wires to cut or tap into, and include all hardware.

 

i think i read some ppl on ls1tech using that box in the forced induction section

 

Or you can just get one of the voltage boosters that works the fuel pump and increases the output by jacking up the voltage to 20 volts or so - Kenne-Bell Boost-a-Pump and I think MSD or someone else might make a similar one.

 

Please post on correct forum..... Moving to "Fuel and Ignition".

 

Sorry about putting it in the wrong place. I did a search in tech, lt1/lt4 and fuel and it came up with 200 in the first two and 4 in the fuel and ignition so i thought it would be more of a performance on the engine i was trying to fix. Does any other part of the electrical need a boost if the voltage drops at higher rpm's? I was wondering if the sensors would have reading that were lower since the voltage to them was lower.

 

I checked on the Kenne-Bell Boost-a-Pump and it was between $200 & $300 so price wise its not close. The only concern would be the extra voltage to the opti and the coil.
