I just checked out the run files and the gearing show 57-88. It look like they pulled in 2nd and 3rd gear probably trying to figure out what was going on with the rev limiter. Run 5, 4, and 1 was done in gearing ratio of 87 and the rest in 57.

Preng, our dyno definitely read low. There's no doubt about that. His highest torque is 216, and his highest hp is 249. LFX on a correct reading dyno should have pulled around 260 with ASE correction. When comparing dyno numbers you have to read it with the same correction factor as others, in this case it would be ASE correction since most other peoples stock dyno numbers seem to have SAE correction factors. The first line is my very first dyno there on the same exact dyno around the same time too when I had the obx long tube and tune only.

Coop, we definitely have to go see tim. Let me know when you trying to do that. I'm trying to go within the next 2-3 weeks

.

Ummm I think the guy doing it was Dennis but Mo was right there because they had to calibrate the machine because my rpms was idle at like 500 but it was showing like 200 on the monitor. I can go up Fredrick next weekend on the 31st if you down. I figured the rev limiter was hindering the numbers

Assuming they are just using a tailpipe sniffer... wondering if their sensors just aren't working right... Because no way should it be that lean at WOT...

agreed... we did pulls on mine in both 3rd and 4th gear... they were basically identical.. Only thing is 4th gear pulls just took longer! LOL

I'll definitely know sometime this spring/summer. We always have a dyno day through my website and I'll be dyno'ing my 5th gen. Unfortunately they always used tailpipe sniffers.

bmorecam · 03-22-2012, 09:08 AM

I know when I talk to Vince before about the LFX he did say that they run leaner than the LLT, now I don't know if it run that much leaner up in the 13's and14's on wot but that does look waaay too lean. What's crazy is that this is the same dyno shop that I been dealing with for a loooong time and their Sniffer always been on point compared to my wideband, sometimes the sniffers tend to read a little leaner but not by alot.

I have no idea what happened there yesterday coop since I was not there but it look like somebody was trying to setup the dyno rather than actually making runs. The gearing ratio 57 is around 4th gear and 87 is 2nd gear. So it look like they first tried in 2nd gear which explain the low torque number, than did 4th gear then went back to 2nd gear. Doesn't look like they used 3rd gear at all. Another thing I realized is that all of the run was done pass 4k rpm. The pulls should have started at 2k rpm.

Hmmmm you might have to get Mo to do another run for me then cause I swore they pulled it in 3rd and I had no idea he was starting the pulls that high either. I was non the wiser or i would have told him to pull it at 2k in 3rd.

apex2112 · 03-22-2012, 11:30 AM

The 2nd video looks like the AFR was around 13.5/13.8 when they got into the pull, above 5000rpm
There was a few seconds of delay before the PE kicked in, so if they are using tailpipe sniffer it may be reading .5 higher that what the wide band would see before the cats.

bmorecam · 03-22-2012, 11:55 AM

I'm going to see what I can do for you bro.. I first want to talk to mo and see what happened there yesterday. I had a chance to look at the run files a little more closely just now and the graph definitely look wacked out and their sniffer was bad, some pulls show a value of straight 10, but.... that does not mean you still didn't get the correct hp/tq results. Just look at tracy's dyno for the ice olator, almost the same crazy looking graph, but not only that, most auto box dynos tends to come out with a crazy looking graph if not done properly.

This is what I think it happened. First of all, It look like they was trying to find the right gearing so it won't get caught by the speed limiter. That explain the 2nd gear pulls. The only camaro they are familiar with is mine but I have a manual which is done in 4th gear, that explain the 4th gear pull. It's also ok to pull the auto in 4th but only if you have the speed limiter removed and if it doesn't affect the rpm signal in the high rpm. The difference in hp/tq is minimal, the lower in gear you go the higher the hp but lower the torque and vice versa. For your car, all of the pulls should of have been done in 3rd starting around 2k rpm. It definitely look like dennis didn't know WTH he was doing.

Regardless of what happened or how the dyno was performed, you was able to still get your peak hp numbers so it was not all bad. The correct result for yesterday's highest is 249hp and 219tq. Once again, this definitely prove that mo's dyno read on the "low" side. Your LFX should make around 260hp+ on a correctly reading dyno with correction factor put in, but like I told you before, a dyno is only a tool to measure mod to mod, not to measure how much exactly your car is putting down to the rear.

PM me and we can set something up for TnT. Maybe we can gather up some mid atlantic V6 guys and have a dyno day

Abstrak · 03-22-2012, 03:13 PM

You got to explain the correction and smoothing to me as I dont understand that at all lol. And I dont see how those numbers would be peak if it bottomed out at 6.5k rpms wouldnt it be higher if the engine was still able to put out power minus the rev limiter?

INTIMIDAT3R · 03-22-2012, 05:47 PM

I like my LFX and the mileage I get.

If I want performance, I'll drive my 2SS/RS.

smoothing basically correct spikes. There's two corrections or "industry standard" used mainly in US. STD and SAE. They are basically preset temperature and condition set by the society of automotive engineers to be able to compare hp/tq numbers correctly. For an example, if you dyno the same LFX in the high elevation, you are going to come out with a completely different number than a LFX dynoed over at the seaside. To make comparisons work accurately, society of automotive engineers created standard and SAE correction factors each defined by preset conditions. I have more info on the first page of dyno sticky up top if you want to know more.

LFX is rated to peak out at 6800 rpm, but I can almost guarantee you that you are not really going to see too much of a difference or any by missing out 300rpm. They say the LLT peak out at 6400 rpm, but usually we crap out around 6k rpm. If it was like 1k rpm short or more than I would say it's possible.

I have to get up with tim and see when we can get in. I will let you know as soon as I know something

fsusmithc2 · 03-23-2012, 08:27 AM

258rwhp/228tq on a Mustang MD-500 was the baseline for my LFX. Not sure if correction was added or not. I need to get back to the dyno now that I've modded a little and see what I get. If the claims from CAI and Ark are to be believed, I should be up in the 280 range. Then we'll have to think long and hard about a tune...

bmorecam · 03-23-2012, 08:58 AM

Mustang and dd used to be known as a heart breakers dyno. They are known to read lower than it should however, loaded dynos such as mustang and dd are the only one's that can be adjusted to read correctly also. Your number def look low considering you have a intake. The intake alone should be good for about 15 on a stock car, but again, dyno is only a tool to measure comparison. Mustang are ase corrected by default.
