Track Time, maybe.
 

Might be heading to the track tomorrow (Wednesday) if the weather permits.

I want to see what I can get out of the car on 93 octane pump gas first. Then I'll try c16 on my next trip to the track. We should have temps in the 60's tomorrow night which would be really good for pump gas running.

I've done some logging and tuning with DSMLink and feel really good about my results so far.

If anybody has DSMLink I can email you the last .dat file I have.

A couple if quick things from the .dat log;

18 psi (will be taking it into the low-mid 20's on pump gas)
46 lb/min (or 350 gm/sec) of air flow @ 7900 rpm
24.1 deg max timing with only .7 deg knock retard (I will bring this down for higher pump gas boosting)
a/f ratio of 11.00-11.45:1 average (calculated based on airflow vs injector duty, O2 showing .96v, I'm trying to buy a wideband O2 as we speak)
coolant temp 169-171 deg
EGT @ 850 deg C

I will be tuning for higher boost, but I wanted a good base line for mixture and timing and I will adjust from there.

I hope it's not raining. :rolleyes:

Re: Track Time, maybe.
 

13.7@113

That's my guess on the first pass. ;)

Re: Track Time, maybe.
 

1/8th mile? :p

Re: Track Time, maybe.
 

Man, I can feel the LOVE all the way down here in Louisiana. :o

Oh wait, it must be heartburn or gas. :eek:

Re: Track Time, maybe.
 

LOL, I'm just given ya shit, call it envy or SPS (JDM knows what that is).

Re: Track Time, maybe.
 

Good luck!!!

Re: Track Time, maybe.
 

Good luck Mike!

Re: Track Time, maybe.
 

Good God...i hope he runs better than a 13.7. 46lbs/min. Must be running what? About a 50trim turbo???

Re: Track Time, maybe.
 

Hit 49+ lb/min at lunch today, 20-21 psi @ 7950 rpm. GT3056 turbo.

Re: Track Time, maybe.
 

You suck.

Re: Track Time, maybe.
 

Well that's a nice "how-do-you-do?" :p

Re: Track Time, maybe.
 

Now get that thing to the track!

Re: Track Time, maybe.
 

Leaving to go shortly.

Re: Track Time, maybe.
 

The Good, the Bad and the UEGO.

The Good
Best pass of the evening
12.48 @ 110.82
1.84 60-foot
18 psi on a rich mix (820 deg EGT)

My last run was a 12.96 @ 111.33
2.26 60-foot (bogged the engine on launch which sucked)

The Bad
72 deg outside air temps (didn't get as cool as we all hoped)
87% humidity (yuk)
93 octane unleaded

The UEGO
Not what I really hoped for, I know there is more power to be made. Just need more tuning. Wideband O2 is my next purchase. I don't trust my stock o2 sensor. Although it's almost new, for the same fuel settings, psi and airflow it could read from run to run, .94v to 1.02v. Probably being effected by heat.

I'm not all that dissappointed though. It's only .3 seconds and 4.5 mph slower than my best time on my 2g 2.0L running c16 @ 25 psi with more timing.

Oddly enough, I did try adding boost (up to 23 psi while reducing the timing, logged .7 to 1.1 deg of knock retard). Didn't have any real effect on the power. I was only able to get 5 runs in, but my mph was from 110.09 to 111.33 from all of them. The increase in mph could have been from me getting closer to getting it right or possibly a little cooler air coming in to play.

Re: Track Time, maybe.
 

I am sure you will gain a lot of power from tuning. I ran 120 mph on pump gas with my 2.0 and 50 trim (12.02 since it was crank walked). I did all of that tuning with just me and Craig out tuning on back roads with the AEM and WB02, it never got on the dyno. Once you get the WB02 you are going to wonder what the hell you were thinking before! I know I will never tune again without one.

Looks like some good shake down runs though Mike, gratz!

Re: Track Time, maybe.
 

AEM UEGO on the way thanks to Shane (ecoli). I'm ready to do some more tuning and get this thing moving.

Re: Track Time, maybe.
 

Sounds great! I can't wait to see what she can do. I really do agree about the WB too. No real reason to use stock crap.

Re: Track Time, maybe.
 

What made u decide to go with the Uego?

Re: Track Time, maybe.
 

I would have gotten the Yugo instead.

Re: Track Time, maybe.
 

It was either the AEM UEGO or the FJO system. The FJO system would have been about $150-200 more. Both claim to be with-in .1% accurate. The AEM uses the slightly cheaper sensor, and since I will be using race fuel at times, that will be a benefit. Also, if I decide to ever go with the AEM EMS, there are no compatability issues. Also the AEM (and the FJO) has a narrow-band simulator so I can run it into my DSMLink ecu without any CEL or drivability problems. I plan to leave the wideband sensor in all the time. DSMLink can log the wide-band output from the AEM UEGO at the rear O2 sensor input of the car.

The Yugo was not an option :p

Re: Track Time, maybe.
 

Basically all WB02's have a narrow band output. The AEM sensor is WAY cheaper than the FJO. You can get them for under $50 a pop. I have 5 sitting at home :D

Re: Track Time, maybe.
 

So when's the next track visit Mike? Or roadtrip to the Elite dyno? :D

Re: Track Time, maybe.
 

Possibly tomorrow night. There will be some cool weather at the track and low humidity (well low for Louisiana anyway ;) ). I think the 19 hour drive might be a little too far to dyno. Now if Shane wants to pack the Dyno-jet down here, I'd be on board all the way. :p

Still waiting on the wide-band to come in. Hint, hint Shane. :D

Re: Track Time, maybe.
 

What exactly is cool weather ;) Tommorows high here is 0 haha. Goodluck, get her tuned.

Re: Track Time, maybe.
 

High tomorrow in the mid 50's. Turbo cars love cold air. :D

Re: Track Time, maybe.
 

Ha, mid 50s. If it was that warm here I would be at the damn beach. Yeah just checked here and it was 28 below with the wind chill.

Re: Track Time, maybe.
 

That's true, but I don't have to use a metal detector to locate my car and dig it out of a snow bank to go cruising either. :D

Call me Jethro
 

I may not be yo daddy yet, but I might be turning into your crazy cousin Jethro :eek: .

New best as of tonight.

93 octane
24 psi
.046 r/t
1.74 60 ft
11.88 @ 116.20

Yes the car still weighs 3400 + lbs w/driver
Yes that was on my 18 inch street tires and wheels.
Still waiting for my wide-band set-up.

Re: Track Time, maybe.
 

Nice job!! Getting closer to 10s!

And we dont have to dig our cars out becuase we havent gotten any snow here yet haha. Our 1st 1" fell a couple days ago. Didnt the south get some snow a couple weeks ago?

Re: Track Time, maybe.
 

That's what they tell me, but I didn't see any. :rolleyes:

Re: Call me Jethro
 

Awesome job bro congradulations.

Re: Track Time, maybe.
 

Thats a pretty good ET for the MPH you ran considering the weight of the car. You can tell by the trap speed the car isn't tuned right yet. Running 24 psi I would say the car should be trapping over 120 even on pump gas. Even with them 18s, but they aren't helping any.

Good run though. Now just get a tune with 30+lbs and some C16.

Re: Track Time, maybe.
 

I had a couple of friends of mine out there, one of which, Charlie, was running his twin t-61 turbo Camaro with a 355 cid sbc. He never could make a full pass with it, kept getting loose and loosing traction once the boost came on (18 psi), especially once it got past the 1/8th mile marker. This is a full race chassis Camaro, fiberglass front cap, tubbed rear, big slicks, etc. He had to let out of his best pass, but it still went 9.65 @ 121.xx mph. The car has gone 8.56 @ 164.xx on his old engine, so we are all waiting to see what the new engine does.

So anyway, none of them are really into DSM's or know anything about them all that much. They are all v8 guys. So on my second pass at 21 psi I hit an 12.224 @ 115.22 on a 1.92 60 ft they thought that was all I was going to see out of pump gas. I told them there was an 11 second pass in there and they were about to see it. Well once I got back to the staging lanes with that 11.88 time slip they were really impressed. I could see a couple of them getting that look in their eyes that this little 4 banger might put a hurt on a couple of their v8 race cars with some c16. Isn't life great?!?!? :p

Re: Track Time, maybe.
 

I'm going to wait until my wide-band is installed. I really don't want to push it that hard yet, not knowing where exactly my a/f ratio is at.

Re: Track Time, maybe.
 

Yeah thats a good idea. Just curious how much timing your are seeing running 24lbs on pump gas? And if you are seeing any knock?

CRAIG

Re: Track Time, maybe.
 

It was a really clean run for timing, except for 4th gear.

1st gear, no knock
2nd gear, 1.1 deg knock in 2 spots
3rd gear, .4 deg knock in 1 spot
4th gear, 3.5 deg knock retard towards the end, probably due to heat build-up in the cylinders.

That was on 18.1 total timing @ 7000+ rpm. 820 deg C EGT.
I plan to take the timing down a little more to be on the safe side. Other than 4th gear, the engine seemed to do good.

If anybody is running DSMLink v2.5, I can send a copy of the run.

Re: Track Time, maybe.
 

Yeah I figured there was some knock retard since your trap speed was a little low for your setup and boost level. But better safe than sorry with no wideband tuning.
