meh, long as u didnt do anything drastic you probably didnt lose anything short of a 1/2 psi. Im just tired of the fail misinformation that is being shown about porting the SC. There is a reason no one shows dynos because they are losing HP....not gaining.

Im not pissed at you as much as the morons on here telling you to do it and that you will get SUBSTANTIAL gains.

you get as much HP from porting your SC as you would by putting a NOS sticker on your fender

... lots of fail in this thread... and in only 2 pages... wow...

Too bad that no one ever read up on their compression, flow and thermal efficiency lately....

stop acting like you are gods gift to porting man. First off I dont have the dyno's anymore. They are with the dealer that owns my car now. Second search the site I know there are dynos of my car before and after somewhere on here as well as for the new era performance cobalt which had a ported and polished blower. Mine was ported on the intake side with the throttle body matched and the triangle was smoothed out not opened very much just enough to create a much smoother contour.

You act like your this god and the only thing you can do is hurt your car. Wrong. Again search the site there are dyno's somewhere. Or ask mike at new era to see what his gains were on thier cobalt. People do gain with a port and polish

the biggest gains I had on my car were the drop in iat's which was the main reason we did it.

by the way no where did i say I got substantial gains, i did say great gains, although in your opinion Im not sure what a substantial gain is.

Also the gains could be attributed to my other mods and that by porting and polishing, we were able to get more out of those other mods

If done correctly this is more of a supporting mod then anything

Even if his IATs did drop, he would have to tune to account for the change and advance some timing for these "great" gains.

And since people arent saying "god my car is running like crap" because they ported the SC, its not making this great difference you all make it out to be.

What did you lower IATs by? 1-5 degrees max? I can understand the drop just from a polish, but the port only freed up air that you were going to be stuffing in at ignition.

You guys are basicly arguing that you can stuff more air through a straw with a wider outlet and you are full of **** i dont care who you are. I call major b.s.

Hook up your HP Tuners and measure PSI at the intake mani with and without the port job.

You lost the compressed air in that intake mani. I could do the SAME thing by limiting the boost in my SC by 50% without using a dremel

unfortunately given that our engine has many nooks and bends, psi is created when forcing cfm in.

increase the openings, decrease psi and increase the potential for cfm.

or would u rather g/sec or kpa?

... CFM... IAT...

PSI is too much of a flexible number to reliably base anything off of...

I did... so far so good.
And I'm not the only one who's done it.... ask many of the past users of Eaton roots blowers... they agree that porting, if done right, is a great mod.

in reference to your last post too. When did I say I didnt tune. Ofcourse I tuned the car after we did it. Why wouldnt you its the only way you can track whats actually happening and get more out of it. Good thing you know everythign I did during my process.

that is a common ricer determination.

Unfortunatley, everyone fails here who ported their SC and says they even got 1 hp. Guaranteed it didnt happen.

PSI is produced because the cfm is walled off by the intake. When you drop psi by porting the SC you lose the potential CFM.

We all know the bottleneck is the intake manifold, not the SC. Your drop in IATs wasnt enough to do the work for this heaton.

Im calling out anyone who ported their SC as B.S. as far as ANY gains short of torque, and it would be barely noticeable. If you open HP tuners and your PSI dropped at the intake manifold then you just lowered the PSI before the intake.....
The intake doesnt change when you port the SC so the pressure would be greater to force the air in creating ..... dun dun dun PSI

WTF are you thinking if you gain power by pushing LESS air in to the intake?

I actually want to see more IDIOTS (yes im calling EVERYONE out) who think they gained even 1 HP porting their SC.

You lost HP...nuff said, you lowered IATs? great, i can do that by lowering my boost to 50% too
