TALON Goes to Dyno

[Silver_2000]

A couple of the TALON guys go to the dyno on a drizzling 55 degree day...

Here is scan of my 1st pull.... It is on the Race side of a JDM superchip running VERY SAFE A/F and timing... The consitency between the runs ~5 min apart and the A/F cushion combined with the fact that I joined the 400 - 500 club makes me VERY happy.. 402 HP - 510 TQ

The last pull was on the street side and only dropped 15 HP... There was only 3 min between the 2nd and third run.... So the motor was really hot and was running A/F that accordingto thier sniffer was almost off the scale rich ( SAFE ) and I still pulled 384 HP and 496 TQ
My old truck with 49,000 miles is still going strong.... Stronger an stronger actually
:) :D

A couple new members of the 400-500 club
The other guys will chime in soon

Member of the 400/500 club too.:)

If I count the converter spikes 426 HP and 522ft-lbs, but really about the same as Doug's.

went but no dynos for me, had to leave early today because I had to go to school. What did they do with the slotang that broke. Nice dyno fellas.

[Logan]

Sorry I missed it. I forgot... Was installing a custom gauge panel in the Cougar... Dammit.

[TxBolt]

I posted on the events asking if yall were going to reschedule the dyno day. I read where it was raining and cancealed. Whats up can we have another one? I need my truck on a dyno bad. Just waiting on a tranny. Oh Doug I will call you Monday. Is that cool? About 4pm?

[OneRedTXBolt]

Great numbers! :tu:

This is how you get to be a member of the 400/500 club with just 4 pounds of boost, single blade throttle body, and an 80mm Pro-M. Run your A/F ratio dangerously lean. I've got some other issues to deal with as well. Probably have a few torched plugs. Go_rila also burped and shut completely off on the second run. Same thing happened at FFW Ennis in September. Wondering if now would be a good time to get a little more conservative with the tune since we are staring at 58K miles by the end of the month. :cool:

[Mark #2]

6er,
Almost stock for me too. :)

[Crawford]

On the first pull I got 386hp and 505tq on the Swanson street chip.
Second pull was 388.4hp and 495.2tq on the JDM street prg.
Third pull was 381.2hp and 495.3tq back on Swanson chip after a computer reset.

The A/F on the Swanson was a full point richer than the JDM. I was hoping to pull off a 400hp run but I am not at all disappointed being that my only mods are chip, filter, #6 pulley, and Denso IT-24 plugs (line mod doesnt count here). Once I get a electric fan kit and throttle body I will probably be there. I got the torque I was after and was only 14hp away from 400 so I am close to my bench racing goal.

I cant way to hit Hallsville and let the rubber meet the road! Hopefully we can come up with a date soon!

I guess the "little things" do add up. :p What were your A/F ratios. Sam? That is where the horsepower is. :cool:

[Ripster]

I was under the impression that it was off due to the rain. Oh well I guess i will have to read the mail more offten.

1st run A/F was about 10.8 (Swanson)
2nd run about 11.7 (JDM)
3rd run about 11.1 (Swanson)

This concerns me. My stock A/F was just about 12.8:1 and with my chip and other goodies I'm looking at about 13.2:1 (which looks pretty close to Sixpipes' curve). Since they were pretty close before and after I thought nothing of it. What is ideal for an A/F number? Does anyone recommend a reburn due to this?

Here's a linky to my last dyno; take a peek: http://www.fordtruckworld.com/showownerpic.asp?u=540&n=77436&pos=1

TRY THIS LINKY!!

Tom

[L8 APEX]

Linky no worky. I like to see the daily drivers/occasional racers no more than 12.1-3 A/F at full boost & RPM. For road racing or constant high speed I like a high of 11.1. If this reading was from Speedowrks or other credible A/F monitor I would recommend a reburn to bring that 13.X A/F down. At least you have the chip with free reburns:tu:

[Silver_2000]

Since I intend to drive mine for some time to come AND I am NOT lookingfor the TOP dyno numbers on the club - I prefer my A/F under 12. When my truck was road tested in July with Horriba A/F meter the A/F was higher than what the dyno sniffer read.. I was runnning right about 11.7-12. So eithere the weather changes affected the tune OR the dyno sniffer being after the cats my be reading a little richer than an o2 sensor in the headers...

I wonder what the Cobra owner with the powerdyne would say about A/F and tunes ??? You know the one that they used a diablo chip to get him 110+ extra horses and 10 min later on the street he blew up ?

Swanson street program dyno run. Down 12 horsepower and a full A/F point from the race program.

[Mark #2]

FYI,
My JDM street program was 10 and the race was the same at Doug's curve. Bottom line= safe.
Mark

[tliss]

I fixed the linky....try it now.

Well, it looks like it's back to Sal for a reburn. I'll have to try to give him a call to discuss.

Here's a thought though...based on the comments here it seems like my stock A/F numbers were too lean. 4/10 difference doesn't seem like much, but it might be. I'll make the changes to be safe.

Terry, I'll give you a buzz tomorrow sometime.

Sorry, I had a brain fart. Didn't mean to be an alarmist. I will talk to Danny Swanson tomorrow about my A/F numbers and post. The more I read, the better I feel about the situation. Here's some pretty good stuff if you can sort through the crap. :cool:

Everything in that thread flew right over my head! I knew I should have stayed awake in chemistry....:mad:

Tom

[Silver_2000]

The D/R competition is ONLY open to Chipped trucks making more than 390 hp ... - See I told you I would change the rules...

In reading that thread it says that more timing can reduce A/F. And that less than 13 is likely better.

Sixpipes, Your truck is clearly NOT running well. Is it plugs or tune or luck or karma ? Not sure. The race gas likely helped keep it together. BUT I would feel more comfortable with a richer reading AND a truck that ran a little smoother.

There is a significant SPIKE in ventilated motors in this cool weather. I don't want to see that happen to ANYONE here.

I DON'T think anyone ( with or without Chemistry Degree ) would argue that higher A/F is safer. And that if you can make decent power with FAT A/F and safe timing you have the best chance of wearing out the floor mats and seat bolster before needing a new motor..

Doug

[Mark #2]

"if you had a misfiring cylinder, you wouldn't have a richer A/F from unburned fuel, you'd have a leaner A/F, from unburned O2."

6er,
This may be your situation based on what I witnessed.

[Badcarma]

I had nothen to do with it!!!:rolleyes:

[Mark #2]

"I DON'T think anyone ( with or without Chemistry Degree ) would argue that higher A/F is safer"

I will dispute :),

13>10

higher=Leaner=unsafer

Talked with Danny today about my A/F and at this point I am convinced there is something wrong with my truck set up.

I have had a number of comments over the past couple of years about my Pro_M 80. 100% of the comments have been, "I've never seen a Pro-M like that before". Come to think of it, I haven't either. I'm going to do a little research and see if somehow I picked up a Pro-M that wasn't calibrated for a Lightning. It doesn't make sense that one of our TALON guys was running a Swanson chip and a "safe" A/F on his street program while I'm running an A/F of 12+ on my Swanson street program, same dyno, same technician.

This is the piece in question.

Aluminum
Serial# 00A2300
Calibration# 966724
99-00 Lightning

Any information on this unit would be greatly appreciated.

[Logan]

Hmmm... Why not try sticking your stock 80mm back on there and see what happens?

[MadMax]

Dennis. This is the same type of Pro-M that I have. I returned it back in 2000 due to the fact that it was not properly calibrated.

They did perform the "recal" for no charge....

[Mark #2]

FYI,
Doug and I made the same HP, he has an 80 MAF and I have a 90 MAF. Doesn't appear that the MAF makes much of a performance difference.

no problemo...e-mail sent <hints enclosed> \


:beer:

[Sixpipes]

Sending the chip back to Danny for a little more fuel. Based on my previous dyno information, he should be able to get pretty close to the target A/F. I'll be going back to the dyno to confirm as soon as I get the chip back. I decided to stay with my current (collector's item) 80mm MAF and tune to it instead of recalibrating or going back to stock MAF. :cool:

[tliss]

Dennis, Let me know when you go to dyno and I'll head out with you. My chip is on it's way to New York for a little more fuel and tinkering as well, and I want to see what happens when it gets back.

Tom

[L8 APEX]

Dennis, maybe you could autotap MAF readings at idle etc.. To give Danny an idea of what it is "seeing" for airflow at a known RPM. I am worried tuning for WOT A/F will not nail the part throttle tuning:confused:
