Fantastic! Cant wait to see it on the track and the look on peoples faces when it launches off

Didn't have torque on the dyno graph only HP and AFR so not sure on that one!

[vlad01]

Can easily work it out, just need rpm and hp from the graph. But I hardly look at torque, HP is work done and that's what matters, HP curve contains all the info you need anyway.

One thing I can tell you from past experience, once it hits full boost the torque stays pretty flat!

Torque reflects the efficiency of the engine. In simple terms Horsepower is the product of the engines torque by how well you can get the engine to rev . By using forced induction you increase torque and therefore can increase horsepower without increasing your engines max rpm.

I enjoyed watching these videos. Nice job https://youtu.be/6bkDKqoGSdU?si=on5DV93UpqGdb1jj

Yep, that's one of the reasons boost makes so much power as not only is torque increased, but it's held right up and past redline more than often. Most if not all NA engines drop torque far before redline, so HP is a lot less than it could be if the torque was maintained otherwise. RPM is the easiest way to make power, NA or boost, boost just makes it way easier to do that.

Installing a ‘hotter’ cam, e.g with a larger duration moves the torque curve higher up the rev range. The higher up the rev range you push that same torque curve the higher your potential horsepower will be. How many times you can hit that max rev range successfully without breaking something comes down to money and engine building skills, both things I lack. Using forced induction to increase an engines torque is a relatively cheap way of producing horsepower and one reason why it is so common.

Hey Wade thanks for the great video links. Just watched the first one and loved it.
