Max Power NA 7afe ????, Dyno Charts Posted Options

[94celicadude]

Hey all,
I am currently building up my 7afe, i have bought a separate head and have already had new valve guides installed, its been cleaned and i have brand new toyota valves, exhaust and intake, i have had the intake ones machined to have more of the performance "penny on a stick" figure, i will post pics soon but for now here is an example Valves.

I am also going to have the Extrude Hone process ( Extrude Hone ) done to the entire head. The current 7afe in my car has a custom 4-1 headers (Headers), full exhaust, intake, clutch, lightweight flywheel, Apexi S-AFC II, bumped timing to about 14 degrees static timing. If i can find a used GT throttle body i will try to make it work, they seem to be fairly similar. Its been tuned and it has over 225k miles on the original engine. The gear box has been rebuild to brand new, and at last dyno the car was putting just about exactly 100 WHP on a 95 F day.

So i figure its already a healthy working little motor. To make this short, i was wondering who has had the highest NA horsepower out of a 7-afe . I am hoping to be able to build my motor to about 120-130 WHP, that would be ideal but im not sure exactly if i will achieve that goal. The bottom end is going to get first O.S. pistons, the head will be decked for a slightly higher compression ratio, and the entire engine will be blue printed. Then the entire crank assembly will be dynamically balanced with the flywheel and all the accessories on either end of it. Then it will all be put back together and have another tuning session on the dyno.

Now i know that it seems like a lot of money to do everything i am, which it is for only 130 WHP, but im looking to make this a great motor for auto-x. And if i have 200 WHP then ill just create a smoke show, so thats why im not just swapping in something else.

**CLIFF NOTES**

Who has the highest NA power 7afe with dyno numbers to prove it?

Where are you getting an extrude hone job done and how much is that costing you. If it is done right you could outflow a 4AGE. I also think that you should look into getting your head flow tested. After you do that you can figure out your perfect lift from a cam and get your cams reground by any cam manufacturer.

i dont know if i will be able to get the head flow tested, my dad used to have a flow bench but he traded it for having his 76 BMW 90RS restored, but if i can find a place that can do that for me i will. I have also worked out that with the size valves in the 7-afe head, the lift on the cam is optimal, i would not gain much over the entire power band by having the cam reground, i know i could gain up top if i sacrificed low end torque, but the thing is like some said, i want to build a good auto-x motor, and i run mostly in the midrange during auto-x so that wouldnt be as advantageous for me. And yes if i swapped another motor in i would be out of my class. Thanks for edo's profile his motor is a piece of art! and thanks for the member that posted his dyno chart. Does anyone have any other ideas on what i could do to push more power out of this thing, i mean except for the obvious previously stated. Thanks for all your comments and support, i will try to take as many pics of my progress as possible and hopefully help you learn with my mistakes *praying for very few*. Any feedback and ideas are always welcome.
