so ive still got some money left over and im still looking to do some stuff to my car. and i was thinking of advancing my timing. from what ive read 12 BTDC will not cause a knock as long as i use a higher octane gas.
i was thinking about purchasing a pair of these http://www.aempower.com/product_cam.asp my questions are. one how much horsepower will i gain from advancing my timing? also i was just want to confrm that our cars run at 10 BTDC stock. any advice or tips would be much appreciated.

I agree with you about the 7a motor as it would not be worth trying to squeeze the extra power out of it but the 5s doesnt get enough credit i dont think. I am currently working on porting a 5s head and I see alot of room for improvement. With a good port, polish and valve job A big web cam would definatly Pull harder in the upper RPM's. I dont see that motor wanting to rev to 7k+ rpms all the time though atleast on a stock valve train. I would/will use a adj cam gear to bring that powerband back down to a useable area. This is my firtst Toyota motor build and a turbo 5s is in the projects list over the winter. I've read alot and have found alot more speculation that hard evidence that the 5s "sucks". But who knows i might be proven wrong and maby it does suck...... As for ignition timing i have read of people pushing as far as 18BTDC on 93 octane. Never tried but when i get to that point i'll let ya know. |
