Why is my car making barely more power than before when I didn't have a cam, valvetrain and race port and polish?

Please check out that thread and let me know, thanks.

 

Please help me out, tell me what you think.

 

You have any idea what valve job was done or not done.

All the porting in the world is almost useless if the valve job is stock.

Stock Vavle Job = Stock Flow = Stock Power if compression is the same.

 

I got a radius valve job........ and as far as I know that is better than most, such as a 3-angle valve job.

My compression should've gone up half a point too because of the y8 head and y8 gasket and I have a feeling that is dropped because he reworked the combustion chambers on the head too.

Anyone have an idea why this happened so i can learn from it?

 

I would do a leak down to verify ring seal and valve seal.

 

Why all that work for a Stage 1 cam! I think that is your problem. You need a bigger cam to make use of the headwork.

Most Crower Stage 1 cams are designed for stock replacement, which means you wont make much over stock with them.

 

I'm just gonna take an educated stab here, wouldn't bigger cams be greatly complemented by upping compression because when compression is upped the cyinder and piston becomes a more efficient pump meaning there is more of a sucking and pushing effect by the piston. If this is so, then the greater "sucking"
effect would make excellent use of the bigger cam. Since I am new to this I'll say as I always do, correct me if I'm wrong, I would love to be enlightened.

On Crower's website they describe their stage 1 cam as "far more aggressive than stock yet has a stock idle". I got it cuz this is my daily driver and I need some low end power cuz I'm not redlining from stop light to stop light.

I think thats my problem in the first place, my cam is fine but my compression is low. I'm guessing that it's low because the guy ported out my combustion chambers too, not just the intake/exhaust ports.

I'm planning on going turbo soon so I think that's all the "compression" I'm gonna need........

Your exhaust manifold creates more suction on the intake than your pistons do!

Yes, I looked at the Crower website last night. If you compare specs then you will see that the stage one cam is only more aggressive on the intake valves, while the exhaust valves lobes didnt change very much.

Stock cams: I-218 E-204; Lift: .397/.367

Stage one: I-228 E-208; lift: .406/.385


I would have used the 63422Y(Stage 2)

Stage Two specs: I- 235 E- 223 ; Lift: .432/.436

So when comparing specs, you really didnt get a more aggresive cam.
