today was dyno day

[jackal2000]

a local shop was charging $40 for 3 pulls with a/f so i went ahead and did it. the car needs more fuel, but im not sure how much more i can squeeze out of the stock injectors.

[jackal2000]

i'll have the video link by tomorrow.

[Bad99Olds]

way to leave me out of the story, im gonna go cry now. told you to man up and upgrade the injectors. lol. ill have that video posted eventually.

[jackal2000]

oh yea. bad99olds tagged along with me. i was smoking him on the interstate on the way home and then he did a ricer fly by and weaved through traffic almost killing an old lady.

[Bad99Olds]

utterly untrue. my speed never exceeded 80 miles per hour on a highway, and there was no old lady or near killing. ur so dramatic. 185.

[Vinalero]

Im always mixed up, does a dyno shows wheel or crank power?

[Bad99Olds]

dyno is wheel. john should be dynoing higher but hes got some gremlins to work out.

Considering your mods, it seems about 20WHP low....but the graph is nice and smooth. I'm sure you know that you haven't enough fuel, so that'll go a long way to getting that extra power you're missing. Still, roughly 230HP/230lb-ft at the crank is nothing to sneeze at.

yeah it looks low, and your air-fuel ratio is WAY too lean, that's like scary lean, if they measured it correctly.

how did they measure the A/F ratio? the stupid clip on thing at the end of the exhaust which is totally inaccurate?

[Bad99Olds]

yep. thats exactly it. the v12 twin turbo merc actually caught the rag on fire that held the sensor in. pretty sweet.

[[ion] C2]

that is pretty sweet, and i can see why it would read lean. the kitty cat tends to get rid of the fuel before the end of the exhaust

[Bad99Olds]

yea, but hes having legit problems. he scanned it and it kicked a kr, and a low system voltage, and i think he said his spark tables are off. theres more hp in there yet. just a matter of tuning.

[cherrington17]

ok... i was gonna say... all that money and work and hes only running 185?? but hes still having issues. gotcha.

jon, when are you gonna have a proper running car, dude!?

[[ion] C2]

stock: 180bhp
jackal: 185whp ~~ 218bhp

but if the A/F ratio was anywhere near accurate those HP numbers will increase drastically with bigger injectors and a tune

[cherrington17]

so jon, you said you have the stage 2 milzy kit? anything else that you upgraded in the engine? (besides not having your injectors not keeping up)

[Bad99Olds]

hes at a barbeque right now, lol, but hes got a ported 62mm throttle body, cai, tog headers, high fow cat, magnaflow muffler, and i beleive thats about it. but yea , one he fixes the holes in the tune and gets those bigger injectors in, 12 more pounds per hour, he should be good.

[jackal2000]

alright, here's the mods:

-custom CAI
-62mm TCE TB
-upper intake is port matched to the TB
-lower intake is ported
-MMS stage 2 heads
-MMS chromoly pushrods (quite possibly the wrong length as there was much debate over this on gagt.com after i already had them installed)
-MMS stage 2 cam
-hypereutectic pistons
-block is bored .005" over
-FFP under drive crank pulley
-TOG headers, ceramic coated
-carsound high flow cat
-2.5" cat back exhaust pipe
-magnaflow straight through muffler
-DHP PowrTuner

a gagt with basically the same setup made 203whp and similar tq. granted, today it was 97* with around 90% humidty so that had an effect on power output. i have to do some math to see how much fuel i can add without going static.

[Bad99Olds]

nah, no math. just guess and check. lol.

depends on the dyno. A chassis dyno measures whp. An engine dyno measures chp. There's even a transmission dyno for testing transmissions.
