Is it worth it?? do they really gain power ?

 

Anyone

 

Depends on if your car is for track only. If not and you're stuck in traffic from time to time, then no way. Takes away the daily driverability in the car completely.

Gains power at different rpm bands depending on size of runners.

 

You want to make sure if you decide to purchase them, you have aftermarket camshafts, pistons, and internals mods already done to get the best performance from them. You should get both low-end torque and high-end power from ITBs.. I've heard that most people make between ~25-50 hp from ITBs, I guess dynoing would be the only proof for that...

 

I haven't heard that. I would have a hard time believing this no matter what other mods the car has.

 

ask turbopwr, he runs ITBs and knows alot about them if im not mistaken.

 

For the s2k... I personally think it is a waste of money...... there are no significant power gains.... the cars throttle response is excellent ( like a sports bike) however as I said before there was no significant power gains... this might have been due to the small runners and trumpets...... for now there is only one existing member that runs this setup and although the thing sounds like a beast, I would not invest my money on that route.....
Oh btw... it those look awesome......
And 25- 50 HP gain is bull.........
