Is LS2 intake better than LS6?
Is LS2 intake better than LS6?
As in the previous test, the manifold was equipped with a 78mm throttle body. Despite the 12mm handicap in throttle opening, the LS6 intake easily outperformed the larger LS2 unit, producing peak numbers of 489 hp and 481 lb-ft of torque.
How can you tell the difference between LS1 and LS6 manifold?
Corvette LS1 intakes did not come with the EGR provision, so it visually looks identical to the LS6 intake. The only sure way to tell if its an LS6 is to flip it over and see if there is a flat bottom, identifying it as such.
Whats better LS1 or LS6?
As earlier hinted, the LS6 is a modified LS1; thus, it has better features. Some of the features include an improved air intake and a higher compression boost output. Additionally, the LS6 has windows cast between the cylinder blocks. All the modifications make the LS6 more reliable than the LS1.
Are LS1 and LS6 injectors the same?
They are the same overall length as the stock LS1/LS6 injectors, and the injector connector is an LS2-style. However, all of the injectors do include a plug-and-play harness to adapt the fuel injectors to the factory LS1/6 (EV1) connector.
Are LS1 and LS6 blocks the same?
Registered. “While the LS1 block has some machined openings between bays, the LS6 block has larger “windows” at the base of each cylinder that better accommodate bay-to-bay breathing. The positive crankcase ventilation (PCV) system was also changed.
Is LS6 a cathedral port?
The LS6 was designed specifically by GM to surpass the LS1 as the best performance head, and it did such a good job that the “243” casting was recycled on the LS2. Aside from the LQ9, which is a copy of the LS6, these are the best performing of the OEM cathedral ports.
What is the difference between the fast LS and lsxrt manifold?
The LSXRT manifold (left) is visibly taller than the LSXR, offering more space inside for longer, straighter runners. Another noteworthy member of the FAST LS manifold family is the LSX RT, where the little “T” stands for “Truck.” For use in applications where hood or cowl clearance isn’t an issue, this manifold has a few new tricks up its sleeve.
What is the difference between LS3 and LS7 manifolds?
The geometry of the runners is actually very similar between LS3 and LS7, with the difference being related mostly to matching the head port location and shape.” One of the benefits of the modular design is that it’s easy to port and modify these manifolds internally.
Will an LS1/LS6 injector fit a 92mm intake manifold?
“The great thing about the 92mm intake is that LS1/LS6 injectors and fuel rails are direct fit parts,” Maxwell explains. During the time when the LSX was out of production, the LSX R was the only option from FAST. “This means the LS1/LS6 guys had to go out and buy new fuel rails to fit the new manifold.
What is the difference between the LS1 and LS6 intake?
Low man on the intake totem pole was the factory LS1, which was down by 14 hp and 13 lb-ft to the early truck intake. The LS6 bettered the early truck intake, but only above 5,500 rpm. The late-model truck intake offered the most power and torque of the factory manifolds, and even out-torqued the FAST LSXR up to 4,600 rpm.
