flyby Posted April 12, 2008 Share Posted April 12, 2008 Iv tested whit a G-tech computer. 0.6 bar(8,7psi) = 225HP 1.0 Bar(14,5psi) = 255hp/270HP (Max) Can that be true? Quote Link to comment Share on other sites More sharing options...
JohnA Posted April 12, 2008 Share Posted April 12, 2008 Why not? Did you think that the two have to move in perfect harmony? Quote Link to comment Share on other sites More sharing options...

johnny g Posted April 12, 2008 Share Posted April 12, 2008 Have you got it mounted correctly and input the vehicle weight correctly? That seems low. Quote Link to comment Share on other sites More sharing options...
Sharpie Posted April 12, 2008 Share Posted April 12, 2008 Sorry but, the G-Tech device just a toy IMO Get it on a dyno! Quote Link to comment Share on other sites More sharing options...
flyby Posted April 12, 2008 Author Share Posted April 12, 2008 Sorry but, the G-Tech device just a toy IMO Get it on a dyno! year I have to. as the car is very fast compar to others cars. I think i sale it. Quote Link to comment Share on other sites More sharing options...

JohnA Posted April 13, 2008 Share Posted April 13, 2008 The absolute power figures you'll get depend heavily on the parameters involved : car weight, friction, road levelness. But the *relative* power figures you've seen are not far off. 0.6 bar v 1.2 bar would not imply twice the power at 1.2 bar (I hope you understand that) 'bar' is static pressure (over atmospheric) at the intake, power is something else altogether (loosely related though). Even if you translate it to absolute pressure figures (adding 1 bar to each) you still won't see a linear relationship with power output. The more you move away from the stock setup, the more suboptimal it becomes (i.e. less extra power for each extra bar) Quote Link to comment Share on other sites More sharing options...

JohnA Posted April 13, 2008 Share Posted April 13, 2008 What I meant is that double the boost doesn't mean double the power. Under theoretically ideal conditions, double the absolute intake pressure could mean double the power - but conditions are often less than ideal, so diminishing returns kick in soon after boost is increased. On a UKSpec returns tail off sharply after 1 bar and even sharper after 1.2. Soon after you get just extra heat and less power (hot air registers as high boost, complicating things further) Quote Link to comment Share on other sites More sharing options...
