Does a turbo add low-end torque?
Differing the compressor wheel size and turbine will lead to completely different torque characteristics. Large turbos will bring on high top-end power, but smaller turbos will provide better low-end grunt as they spool faster.
How big should a cam be for a cylinder head?
The cam’s airflow capabilities should closely match those of the cylinder head to produce maximum torque. “If a cam is capable of flowing up to 700 cfm of air, but the heads peak out at 600 cfm, the cam is too big.” The variables that must be considered when choosing a cam or having a custom cam ground include all of the following:
How much torque does a truck CAM add?
As indicated previously, the cam offered gains as high as 59 hp at 6,400 rpm, but for truck owners, the real story is the extra 20 ft.-lbs. of torque offered from 2,500-4,500 rpm. Combine that with an idle vacuum of 21 inches, and you have a winning combination for real truck owners. …
What kind of camshaft do I need for a small engine?
• Engine Displacement – A smaller displacement engine usually needs a shorter duration camshaft for good low end torque and throttle response. A large displacement stroker motor, on the other hand, can usually handle more cam duration without sacrificing low end torque and throttle response.
How much torque does a BTR CAM add?
After installing the BTR cam, the peak power numbers jumped to 385 hp at 5,500 rpm and 393 ft.-lbs. of torque at 4,700 rpm. As indicated previously, the cam offered gains as high as 59 hp at 6,400 rpm, but for truck owners, the real story is the extra 20 ft.-lbs. of torque offered from 2,500-4,500 rpm.
What kind of torque does a camshaft have?
Good high rpm range. Good low end torque and response in 1800-2600 rpm. Good mid range torque and response in 2400-3200 rpm range. Good mid range torque in 3000-4000 rpm range. Good mid to high rpm torque in 3800-5000 rpm range.
How to match cams and cylinder heads in small block Chevy?
You can copy and paste this link to share: https://www.chevydiy.com/how-to-match-cams-and-cylinder-heads-in-small-block-chevys/ While building a high-output race engine is very complex and expensive, engine builders face a much less challenging requirement than street engine builders.
Why is it important to match cams and cylinder heads?
This deserves no more emphasis than in this chapter on matching camshafts and cylinder heads, since the integration of camshaft valve timing with the cylinder head is critical if your goal is optimal power.
Can a tappet cam be used as a cylinder head?
For street engines that see more street cruise time than passes down the quarter-mile, a flat tappet hydraulic cam with conservative duration figures matched to a medium-size aftermarket head not only makes great horsepower, but also deliver excellent torque that can make a street engine a ton of fun to drive.
