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

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?

thanks to both Lagos and Hurley for the props,

i finally figured out what my oil leak problem was, turns out that the vavle cover gasket was leaking from the top where that semi-circular plug goes. So after all the time in taking the belts and timing covers off, i re torqued the oil pump bolts and found them all properly tightened.

So i was a little fast with my conclusions and placing the blame on the machine shop, they in fact did a great job.

A little update:

Motor now has about 800 miles on it, runs strong, and pulls even stronger up top, cant wait to get the miles on it to have it tuned and give you guys a new dyno chart

After i fixed my oil leak, i have not had one problem since, the only thing that i am unsure of is that the valve train makes a funny noise, and its very hard to explain but here goes anyways.

It is most definetly NOT a valve tick from too big of clearances, but it almost sounds like it is a sound of the entire valve train being slightly too tight?... that is the only way i can describe the noise, i will try to take a video and post it up, maybe all the genuises on this site could give me some insight.

Despite that noise, the engine runs extremely smoothly, and it pulls like never before...i am overjoyed with the way things turned out.

Check back for another update in a few weeks to possibly see new dyno charts..and possibly one of the most powerful NA 7AFE motors around.. i hope *crosses fingers*
