Contour Enthusiasts Group Archives Forums General Dyno and Drag Latest dyno results

A little background, car has had an extremely difficult time starting when cold lately.
Like, EXTREMELY difficult. I'd swear the crank was broke or something...
Anyway, I get the cash together and call up Keyser at Streetflight (thanks man!), give him my codes and order a chip. Get chip, install 24pph injectors and chip. Clear codes and fire up - NICE! Runs so much smoother. Almost all low end stumbling is eliminated. They did an excellent job with a mail order chip. I highly recommend Chris and Streetflight.
Problem is, car still has a hard time starting when cold so I'm like, hmmm, maybe I need a dyno tune.
As it turns out a friend of mine was following some threads in the SHO forums about an upcoming dyno day. She sends me the link and it's for a website called Dynoperformance and the speed shop is Xotic Motorsports.
So, I sign up for both website and dyno day. Three pulls for $40. More for tuning purposes than bragging rights because I knew something was definitely not right.
Well, results? 185 hp and 179 ft/lbs of torque. I'm down almost 20hp from my dyno last year and now I have a means for tuning this thing. WTF^^ mate?
In the mean time (i.e., between installing chip and dyno runs) my car had CEL's return so I had those read at the same time.
My car is running lean (?), at least the computer thinks it is, but my dyno is way past 10:1? WTF^^?!?!!
So I drop it off at my uncles shop yesterday to have a look at that and the oil leak (not even going there) and he thinks that there is a pretty massive air/vacuum leak fooling the computer into thinking it's running lean and causing the front bank to misfire.
Here's a link to my dyno graph and list of codes on that day: WTF^^?

So at this point I'm thinking saving up for a full 3.0L swap with a newer transmission (My synchros are SHOT - 122k miles on the original tranny) and pretty much kinda following in "King Demons" footsteps.
Ok, a lot like.

And for those of you too lazy to click on the link:

(I know there's a lot of you out there. I'm one of them usually. )

Anybody with any (helpful) input would be appreciated.

John-

You have PM.

Dyno deffinitely shows a very rich system. Maybe your car is running lean somewhere and your computer is pulling timing creating it to run on the richer side.

On the bright side, you've got the makings of some good low end tq.

It's sad to see an engine w/ so much potential...not performing as it should. Hope it works out well.

Me too. Just got a call from my uncle and she's all done. There WAS a vacuum leak - idles much nicer now.
Going to try to get a dyno set up for this weekend as I'm doing Mid-Ohio next weekend.

Schweet!
Let's see what that chip does for you now!

[/Flounder voice]Oh, BOY! This is gonna be GREAT!![Flounder voice]

Thanks guys, I appreciate the enthusiasm.

Anyway, since I updated my website and I can't edit my original post:



Dyno is on for 12:30 on this Saturday. Anyone up for a trip?

Still not happy.

There definitely was an air leak present.
Did not clear the codes.
Did not pull the chip.
Definitely not happy.
I feel it may be having a problem with the ignition at this point...
