camshafts

[wouter86]

i`m working on a project for school and want to show what different kind of camshaft can do for your car.everything is static except for the camshafts.what i mean is i am gonna put my original 4age on a dynobench and then I got a nice graph of power and torque development.

Next i`m gonna put in other camshafts with a longer duration and a higher lift and again put it on the dyno.Then I have 2 nice graphs which give me some inportant information and answers.So that`s what i wanna do.So you might think "what a waste to buy 2 camshafts for a project" but hey I wanted to tune that thing anyway.

The only difference between the setups are the camshafts,everything else stays the same (standard air filter,head,exhaust and so on).

When the project is over i probably have an engine with not so much extra horsepower because if you only change the camshafts you won`t get much extra power unless you upgrade all other systems(intake,compression ratio,exhaust and so on).so after that I want to install carburettors or ITB and raise the compression,that`s about it.

I read at Billzilla`s site that you need camshaft around 272 degrees for 150 hp, so I want to put those in the standard setup.

Well now that i think about it, we can have a little quiz.How much horsepower do you think the standard 4age will gain with only other 272 degrees camshaft?Or do you think it doesn`t run at all?

It`s a 1984 corolla gt coupe with an AFM (124 hp?)

Any tips and help are welcome!
