Frequently Asked Questions (FAQs)
1. What is the difference between L19 and ARP 2000 rod bolts?
L19 rod bolts are made from a very high strength material and can deliver a clamp load at 260,000 psi. They are primarily used in short track and drag racing applications where the clamping capability of ARP 2000 bolts is exceeded.
2. Are LS connecting rod bolts reusable?
On a GM LS engine, the cylinder head bolts are not reusable, as they are torque-to-yield (TTY) fasteners. The connecting rod bolts are also TTY but can be tightened up to three times for bearing checking. However, it is important to note that the balancer bolt is also a TTY fastener, while the intake manifold, rocker arm, and rear cover bolts can be reused.
3. What is the difference between 1st and 2nd design rod bolts?
The first design rod bolts have a single dimple/mark on the head and do not have a retaining sleeve on the shank. The second design rod bolts have two dimples/marks on the head and have a retaining sleeve on the shank.
4. Are ARP bolts stronger than Grade 8?
Yes, ARP bolts are stronger than Grade 8 bolts. ARP's Custom 450 alloy has a higher yield strength compared to Grade 8 bolts. While a typical Grade 5 bolt has a tensile strength of around 120,000 psi and a Grade 8 bolt is in the 150,000 psi range, ARP fasteners have even higher yield strengths.
5. What is the HP rating of ARP L19 rod bolts?
Eagle H-Beam rods with 7/16" ARP 8740 bolts are recommended for use up to 800hp. With 7/16" ARP 2000 bolts, the recommendation is up to 1300hp (V8). If using L19 bolts, the recommendation is up to 1500hp.
6. What is stronger H-beam or I-beam connecting rods?
Both H-beam and I-beam connecting rods can be strong, depending on factors like material, weight, and cross-section. However, all other variables being equal, H-beam rods are considered the strongest design.
7. Do longer connecting rods make more power?
Changing the length of the connecting rods with respect to the stroke of the crankshaft can have advantages in certain situations. It may allow the same number of cubic inches to deliver a little more power or a little longer ring life.
8. What happens if you reuse torque to yield bolts?
Torque-to-yield (TTY) bolts are designed to stretch during installation and should not be reused. Reusing TTY bolts compromises their integrity and can lead to failure due to the stress caused during the initial installation.
9. Does connecting rods increase horsepower?
Connecting rods play a role in handling engine power. Most stock connecting rods can handle up to 25 to 40 percent more horsepower than an unmodified engine was originally designed to produce. However, to handle higher horsepower levels, aftermarket connecting rods may be required.
10. How much horsepower can I-Beam rods handle?
Stock I-beam connecting rods in a V8 engine can handle upward of 400 horsepower and 6,500 rpm. Beyond those performance levels, aftermarket connecting rods should be considered.
