Are ITBs worth it?
Aside from a snappier throttle response, one of the main benefits of running ITBs is the additional horsepower that can be gained with them as more air is able to enter the engine at a quicker rate due to the air inlets being placed on each cylinder.
How do I choose my ITB size?
As a rule of thump if the flow capacity of the head is known then the ITB should be in the range of 120-140% of the head flow. But this all depends heavily on the assumption that the intake runner/port of the original engine is the optimum size in the first place!
What are the advantages of ITBs?
In an engine with ITBs, atmospheric pressure builds outside each cylinder, so when you open the throttle, air enters instantaneously. ITBs also help reduce pumping losses at partial throttle.
Do individual throttle bodies add power?
In high horsepower engines, individual throttle bodies also tend to flow air more efficiently, freeing up power and complimenting high lift cams or high levels of boost.
Can you put ITBs on a turbo car?
From what I know ITB’s are an N/A only application. This being due to the fact that ITB’s are usually accompanied by intake “trumpets” which would not allow for a seal between the turbocharger compressor outlet and the intake ports of the engine. This would not allow you to build boost.
How much horsepower do throttle bodies add?
A bigger throttle body means more air And since the engine is basically a large air pump, increasing the air intake level will increase the engine’s power output as well, in some cases by up to 15 to 25 hp.
How do you calculate CFM for throttle body?
CFM = (350 x 6,500) ÷ 3,456 = 658 cfm at the power peak These are the engine’s theoretical air requirements if we didn’t have all sorts of interference and restriction from carburetor venturis and throttle plates, manifold runners, intake ports, valves, and so on.
Can you put ITBS on a turbo car?
Why are ITBS expensive?
ITB’s tend to be very expensive because of the precision and machining required. On average, they can cost 3-6x more than a single throttle body upgrade. Besides high costs, there are a few other concerns and disadvantages when it comes to ITB’s.
Can you boost ITB?
What happens if you put a bigger throttle body?
Do you need a tune after throttle body?
For pre-2005 vehicles, a tune is not required with the addition of a new throttle body. For 2005+ vehicles, a tune is recommended for throttle body changes & updates.
How much CFM does a 90mm throttle body flow?
1,147 cfm
According to testing performed at Kenne Bell, the stock ’10-up Camaro SS 90mm throttle body flows 1,147 cfm.
Can you do ITBs and a turbo?
Yes it can be done.

What is the function of the ITB?
The ITB, being a tendinous extension of the tensor fascia lata (TFL), shares the same arterial supply: Function. The action of the muscles associated with the ITB (TFL and some fibers of Gluteus Maximus) flex, extend, abduct, and laterally and medially rotate the hip. The ITB contributes to lateral knee stabilization.
What is the difference between a 2T-G and a 2T-GR?
The 2T-G has a compression ratio rating of 9.8:1, the 2T-GR has 8.8:1. The pistons are each fitted with two compression rings and a single oil ring.
What does the ITB and TfL have in common?
The ITB shares the innervation of the TFL and gluteus maximus via the superior gluteal nerve (SGN) and inferior gluteal nerve (IGN) The ITB, being a tendinous extension of the tensor fascia lata (TFL), shares the same arterial supply: Function.
What is the bore and stroke of a 2TG engine?
Bore and stroke are 85.0 mm (3.35 in) and 70.0 mm (2.76 in), respectively. The 2T-G engine has a twin sidedraft 40 mm (1.6 in) Mikuni-Solex PHH carburetors and produced 115.6 PS (85 kW; 114 HP) at 6,400 rpm of horsepower and 142 Nm (14.5 kg·m; 104.8 ft·lb) at 5,200 rpm of peak torque. Compression ratio rating is 9.8:1.
