I decided against showing pictures of the completed project as its a prototype and doesn't really look all that good. in its completed form.

Driving the car around is a bit of a strange experience because in most situations the power isn't really noticed due to how the cams behave, but I can light the tires up with ease without a clutch dump, and hold it well into 2nd gear, but this has created a bit of a problem for me as I now am having trouble getting traction coming out of corners, the tires blow away at part throttle pretty easily.

I don't think I gained much top end if any, and I'm pretty sure I lost some at the bottom but in the middle it feels really really strong much stronger than a little 1.5 should feel. Again I don't want to post a video of this just yet until I figure out this interference issue.

Glad it's putting out some power :)

glad to see this is completed.

xnamerxx · 12-10-2012, 06:02 PM

Yeah :) I just can't wait to get it on the dyno. All in all this project has at least forced me to learn far more about engine dynamics than I ever expected to know.

G.I. JOOOOOOOOOOEEEEEEEEE.....

justjesus · 12-12-2012, 12:42 PM

LOL
I knew someone would get that!

Autocross72 · 12-24-2012, 06:38 PM

Any Dyno results yet?

xnamerxx · 12-25-2012, 05:46 AM

Not yet, I've been out of town. I should have it done some time in the next 2 weeks depending on my schedule.

xnamerxx · 12-27-2012, 03:07 PM

Well the car is going in for a dyno tomorrow, anyone want to guess how much power it'll make?

Stock was 120/121.

tooter · 12-27-2012, 03:34 PM

Take a video of the dyno run so we can hear how it sounds.

xnamerxx · 12-27-2012, 03:50 PM

Will do :)

Bluevitz-rs · 12-27-2012, 03:55 PM

I'm going to go with 130/122.

that is true if your using a low quality flex-joint. Ones like the premium Vibrant units feature a very smooth liner that is not restrictive at all.

Im glad you got it all done & i cannot wait to see the results!

To everyone that said I needed a resonator to fix my issue, you're dead on the money. I got bored today and decided to kludge the stock muffler than the stock mid pipe onto my short/light exhaust just to see what would happen. First I stuck the stock muffler on and the exhaust sound didn't really reduce pretty much none at all it was quite loud, than I stuck the mid pipe on there and while at idle was quieter it still wasn't all that quiet but during revving the it lost that annoying low pitched drone and sounded pretty nice. Looks like I need to add a resonator to this exhaust to fix the low pitched drone.

malibuguy · 12-28-2012, 10:03 AM

^ look into the Hushpower shorty. they work extremely well, and they tuck up well under our cars.

xnamerxx · 12-28-2012, 04:35 PM

Well the numbers are in, It gained 6.5 hp and 4.5tq over a DC Sport header. Not overly impressive but there was some decent gains in midrange torque.

A video of the dyno run.
