Development Blog : F90 M5 Sedan
The program: CarBahn Concept Cars are being tested on a race track prior to development and then retested afterwards to quantify the results. Every high end, high-performance car regardless of brand is evaluated for what its best intended use is and then it is placed into Category 1 or 2. After its category is selected,
2WD vs AWD – Which one is better?
In years past, I have always preferred 2WD over AWD. This is because older cars with naturally aspirated engines didn’t make anywhere near as much torque as those with modern turbocharged engines. 2WD could easily handle the power and accelerate out of the corners well, plus 2WD cars were lighter and had a better balance
How Much Should I Lower My Street Car?
The most common mistake I see when modifying a car is lowering the car too much. We all agree that cars look better lowered, but if they are lowered too much, it adversely affects the handling of the car which is the reason we lowered it in the first place. Many bad things happen when
How To Make More HP On A Turbocharged Car Without Breaking It
Modern turbocharged cars are capable of making much more torque than HP. This is because the turbochargers are small sized to reduce turbo lag. In addition, the exhaust manifolds are also very small to further reduce turbo lag. The engine is designed around the lower boost and smaller turbochargers so the compression is too. The
Too Much Torque 2
My last post was on the performance issues you might run into when your car is creating too much torque. The issues don’t end on the racetrack though, they continue in the shop. Increasing torque heightens the likelihood of mechanical problems throughout the car. Torque increases wear and can eventually break both the engine and
Too Much Torque
I was recently looking at the specs on the new Porsche GT2 RS. Really cool car. 700hp and 500 lb/ft torque. It reminded me of a tech tip Tuesday video I made when I owned Dinan about why more torque is not always better. (link to video) You see, more torque does not always make
Deferred Maintenance
Having been in the car repair business for 39 years it still surprises me how many customers defer important repairs that will cost them many times more down the road. For example, water hoses dry out and fatigue over time and have a usable life of around 8 years or 80,000 miles. Changing a set
Comparing the Cost of a New and Used Car
When customers bring out-of-warranty cars in and get a large estimate for repair, they often talk about selling instead of paying to fix the problem. That first out of pocket bill can be a shock. But while repair costs are not always as predictable as a car payment, they are usually 66% to 75% less
