How much HP does a FAST 102 intake add?
14-16 hp
The big 102mm intake showed us a gain of only 4 rwhp-it didn’t respond to the CNC-ported heads and bigger cam we previously tested. When tested on stock LS3/L92/L99 engines, it has shown average gains of 14-16 hp.
How much horsepower does a FAST LSXR intake manifold have?
FAST® engineers teamed up with airflow specialists at RHS® to develop polymer intake manifolds for GM LS based engines. Testing on a near stock LS7 engine with a Big Mouth 102mm Throttle Body™ produced gains of 16+ horsepower, and 26+ rear wheel horsepower on a 500c. i.
How much horsepower does a 102mm throttle body add?
The 102mm throttle body upgrade dropped the vacuum present in the inlet tract by 0.29 inches and increased boost pressure by 0.3 psi which equated to an extra 8 hp. Testing at higher boost level (12.8 psi) resulted in and increase to 13.2 psi, a drop in vacuum of 0.31 inches and 26 additional horsepower.
How much HP does a FAST intake add?
FAST (Fuel Air Spark Technology) has a new LSX 92mm intake on the market made of stronger composite materials than the OE manifolds. FAST claims the new LSX 92mm intake will add 20-plus horsepower to the Gen-III LS1, LS2, LS6, and LS7 engines.
What size throttle body does a LS3 have?
But on the dyno, the LS3 intake ran like a champ. Prestige paired it with a Holley Sniper 90mm throttle body—the same size throttle body that the OEM manifold came with.
Does a bigger throttle body give you more power?
A bigger throttle body means more air Car ID reports that “packing more air into your engine allows more fuel to be burned, which creates more power.” Fortunately, there are sensors on your engine that monitor its air/fuel rate, so you car’s ECU should be able to compensate for the added air.
Is a fast intake worth it?
Without SIGNIFICANTLY increasing the engines BREATHING ability, The FAST Intake will NOT be worth the expense. You will need a bigger CAM, better heads to take the better air flow of the FAST Intake to its full capability.
Do intake spacers do anything?
One of the main benefits of a throttle body spacer is an increase in horsepower. Ultimately, the spacer increases the air velocity which causes an increase in atomization. Also, the spiral flow that results from a throttle body spacer offers much better combustion.
Are bigger throttle bodies worth it?
While that formula works for everyday driving, it’s not optimal for those seeking more performance out of their cars. So when you add a larger throttle body, you’ll feel a sharper increase in the engine’s responsiveness, especially at a higher RPM, since the engine’s airflow is increased.
Is bigger throttle body better?
A bigger throttle body can only suck so much air if restricted by your cold air intake. Other things that effect if the bigger throttle body will truly make more power is ported heads, cam selection along with exhaust setup.
What size is a stock LS3 throttle body?
See all 11 photos For the OEM intake test we used a Holley 90mm throttle body. It is the same size as the stock LS3 throttle body.
How much HP do throttle body spacers add?
With a throttle body spacer, it is possible to increase the torque by 25 ft lbs and add up to 18 more horsepower. Not all throttle body kits can be used for all engines. Ensure that you get a kit that will work for the make and model of your engine. These spacers mainly benefit older engines.
What size throttle body is on a Tbss intake?
90mm
The throttle body opening on the TBSS intake is 90mm.
How much HP does a Tbss intake add?
473 hp
Equipped with the TBSS intake, the power numbers increased to 473 hp at 6,800 rpm and 419 lb-ft at 5,300 rpm. The TBSS intake improved the power output from 4,500-7,000 rpm.
Is a throttle body spacer worth the money?
Ultimately, the spacer increases the air velocity which causes an increase in atomization. Also, the spiral flow that results from a throttle body spacer offers much better combustion. If the vehicle has a carburetor, then the spacer improves the vacuum response which increases the performance.
