[Yota4life]

The fun begins!

[Duffil [OP]]

I hope so.

I should probably explain myself, and my results.  I got the cam specs for just about every aftermarket cam made, and made a cam file in Desktop Dyno, where I have my exact engine setup saved.  I changed cams back and forth between what I am currently running, and all other options, finding that with my specific setup (according to the DD, mind you) that I could not get as much torque as low in the powerband as I currently have.  I could get more HP or more torque, but it always fell higher in the RPM range.  I did notice, however, that if I changed the cam timing (ie, adjustable cam gear) I could get a torque boost all the way from idle. So I went with an LC cam gear.

Damn your sh*ts gonna be fast! haha

Damn your sh*ts gonna be fast! haha

advance the cam for torque

[Jud]

advance the cam for torque

Would advancing my stock cam create more torque?

[Duffil [OP]]

Would advancing my stock cam create more torque?

yes.  for $135 you too can increase the performance of your Toyota R-Series engine.  maybe if I get bored tomorrow, I'll run a comparison on a stock 22R with the cam advanced and post it for you.

That would be sweet. I am planning on doin a timing chain, water pump and all that good stuff here pretty soon. Maybe I can soop it up a little while doing all that. haha

no, it is the bolt under the damn distibutor.  I was loosening it and it was one of those "...that didn't feel good...give it another twist. POP" type of breaks.

[skipnrocks]
