Dyno Run!!!

[nacklas]

SO I put my L on the dyno for the first time since havin put on a few mods. 4lb lower, Big Mouth TB, CAI, upgraded MAF, Magnaflow cats and catbat exhaust and tuned by Terry. In the 1/8 I ran 8.3...Didnt do the quater. We measured rwph and this is where I think the dyno may need to be recalb....because it said max power was 467 to the wheel. And I find that kinda hard to believe. So what do yous guys think???:icon_question: Also after the runs my exhaust manifolds where bright red:icon_exclaim: The instructor said its cause my tune is making me run lean. Durning the run my A/F was bout 14.6 or so. Any feed back would be awesome:tu:

[slick-svt]

Well you a/f should be around 11.5, were did you have the dyno done? Yea it is lean.

[L8 APEX]

You may have at that lean! I would change your fuel filter and do a fuel pressure check. 11-12 is where you should be WOT. When wide band sensors go bad they read lean. I have never seen L manifolds glow you have fuel issues for sure if they did.

[tiffo60]

if its that lean consider yourself lucky to still be driving it:tu:

at the very least im suprised you still have the ground straps on all your spark plugs:icon_mrgreen:

[nacklas]

I changed my fuel filter bout this time last year...i had it dyno at school. they have dyno there..it a mustang dyno..they put a bullit and an mach 1 on it that today to. bullit 236 and he mach1 284. so after checking the fuel filter what else can i do to get wot into the 11 or 12's..terry would i need to come out and see you ?

[L8 APEX]

Read my post asshat, check your fuel pressure. I have tuned a hundred stock trucks with pulleys even on a stock tune they won't run over 12.5 a/f. You have a fuel or maf issue it is not the tune.

remember like Tiff says lean is mean until that shit blows up:D

You are not making 467HP with a 4lb lower.
ColorApproximate Temperature°F
Faint Red 930
Blood Red 1075
Dark Cherry 1175
Medium Cherry 1275
Cherry 1375
Bright Cherry 1450

My EGT runs around 1350 F on hard runs, so I wouldn't worry about the color, just the A/F, but I seriously doubt that was correct either.

Get a wide band O2 and see what that reads, a lot cheaper than a new motor.

[WA 2 FST]

An 8.3 in the 1/8th is going to = ~12.8-12.9 in the 1/4, so the truck is making more like 380rwhp, not 467.

Nevertheless, as others have said... assuming the wide-band at the dyno was correct (and it may not be), you need to do as Terry said... tonight.

Best of luck.

[nacklas]

Yeah I agree my L is not making that!!! Because last year the dyno got stuck by lightning. And they just got it back up and running. ATI is where i go! Thanks for the info.:tu:

[99WhiteBeast]

Why would you need an upgraded MAF for those mods? I don't understand that.

[Ohmsby]

get one of those tornado things it will make the truck faster for sure

that would be the vornado.. gave me 15 more HP and 10 more mpg.. :evil

because i have an '00 and it came with 80mm...so i put on an 90mm! those things really work!!!!

Just FYI, I dynoed my 00 with a 90MAF, KB blower up to 15 PSI and the stock computer handled it just fine.

We also know that your truck is a freak of nature from Ford and no one knows why it hasnt blown up yet either.. :evil:evil

Did you like it there? I heard alot of bad things bout it!!! Yeah I think this dyno here is way off... It cant read rwtq and the mph is off too! I would like to have someone come out that knows what there putting out and see how bad its off!

Simple Quick racing in Benbrook is around 75 an hour I'm going to try them out friday and I'll let yall know if they're good or not.
