FAQ’s

Vehicle Maintenance

  • Question: My car has as on-board computer and doesn’t require maintenance–right?
    • Answer: Periodic engine maintenance is as important as ever, perhaps even more so because the computer is able to camouflage some problems.
  • Question: I don’t need to take my car in for a tune-up — right? My car’s electronic system will always let me know if there is a problem by turning ON the CHECK Engine light–right?
    • Answer: Engine performance symptoms are subtle even impossible to detect on today’s vehicles. Periodic diagnostic and maintenance checks help keep your vehicle running trouble-free for years.

B & G’s Shop

  • Question: Sometimes when we price shop your prices are higher than other shops. Why?
    • Answer: When our technicans our repairing your vehicle all factory tolerances and torque specs are followed, when was the last time you seen a techincian torque the bolts on your valve cover, believe it or not there is a torque spec for these bolts and at B&G we take pride in knowing that when a vehicle repair is performed on your vehicle the repair procedure is done correctly according to factory procedures and specs. We also price our jobs using Mopar Parts or in some cases high quality after market parts that our technicians feel confident installing. Are attitude is if we won’t use it on are own vehicles we sure won’t install that part on your vehicle. Sure we could cut corners not worry about torque specs, find ways to short cut factory repair procedures or install low quality after market parts to increase our shop profit margin. But the bottom line is that would be an injustice to you our valued customer and the reason why B&G has been around for over 25 years repairing your vehicle right the first time!

Vehicle Tuning

  • Question: What is detonation, and how can it be controlled?
    • Answer: Detonation is often referred to as engine knock. This condition occurs when fuel ignites early i.e. before the piston reaches the position where the spark ignition is scheduled. This means that the ignition explosion is trying to expand a cylinder chamber that is shrinking in size. When this firing pattern occurs it attempts to reverse the direction of the piston and the engine. When detonation occurs, the internal pneumatic forces of the piston can actually exceed 10x the normal forces acting upon a properly timed high performance engine. Early detonation is generally caused by excessive heat, extreme cylinder pressure, improper timing of the ignition system, inadequate fuel octane rating or a combination of these factors.
      The most common factor that causes engine knock is excessive heat. Additional heat is produced in an engine as it generates an increased quantity of power. Today’s pump gas only tolerates a finite amount of heat before it ignites. If this measure of heat is reached too early in the engine cycle it causes detonation. Although adding a supercharger to an engine rarely causes detonation it does create additional heat. A forced induction engine actually produces far less heat than a comparable normally aspirated high compression engine. To address the issue of increased heat an intercooler may be added to the supercharger system. An intercooler is a natural solution for forced induction and is included in many supercharger kits on the market today.
      For engines currently experiencing detonation problems, the addition of an ignition/timing retard system, the use of higher octane fuel, or the addition of an intercooling solution may be used to address the issue. Ignition retard systems can be helpful in certain situations, but can greatly reduce the horsepower output of an engine. Any reduction in timing reduces horsepower. Reduction in timing can save a motor from detonation, but the excessive heat which was causing the detonation is still present. Intercooling is a more desirable option in most cases because it actually removes the heat which causes detonation, and allows higher boost levels to be safely run with full timing on pump gas. This setup produces the maximum benefit in terms of horsepower gains and engine protection, many times without additional maintenance or hassles.
