Actual Dyno CHARTS.

wow, the torque peaked at 2600...isn't the factory torque peak supposed to be at 4000? it is nothing short of impressive... for an l82(smirk)

That's not where it peaked, those numbers are skewed from the torque converter being unlocked(read the first page or two in this same thread about *this*). You can see where the converter locks ~3600rpms or so and then the torque peaks right around 4000rpms(look at the number readouts). 144.8 ft-lbs @ 4,000rpms w/ 20% drivetrain loss correction = 181 ft-lbs. Factory rating is 185 ft-lbs @ 4,000rpms, so it's pretty much spot on...

that makes more sense now.

so he's either got a really tight drivetrain or he has the most well maintained motor in america.

I vote the later....LOL

 

i've taken great care of it...

 

 

if you know me personally, you'd know i'm anal about maintenance.

I'll get my dyno scan up next week. I did 134whp and 165 TQ on my 95 3100.

62mm TB from rsm but my plenum was still stock at 52mm so at best this caused a loss in HP cause of turbulance.

FFP UD pulley

2.5" crushbent exhaust with high flow cat

plugs/wires

Wrapped short ram intake

16.2 best 1/4 n/a.

15.4 with 55 shot nitrous. no dyno results

15.01 with 75 shot nitrous no dyno results

[adam_murphy]

04 Comp G, L26, Cartuning Turbo T-66 3" DP kit(intercooled), 12.5 psi, XP cam, Ported heads (Stock vavles), 79# Racetronix injectors, Racetronix Fuel pump rewire. NO meth, 20+ psi in the spring.

 

Car is in winter mode.

 

This version of the Dynapack reads typically - 10% of a Dynojet.

[ismellrealbad]

 

was this with the rockers and valve springs? because if not you have my exact same mods. do u know any other variables like baro, ambient and intake temps?

[pwmin]

bump

[dbtk2]

I was just thinking while looking at this thread, that maybe at the beginning we could list each members results, just like their name, the car, and the whp/wtq numbers? Make it easier to find out what someone made without looking through 10+ pages of dynos just to find it.

 

Just a thought...would probably be a bit of work so I dunno how realistic it is.

[GTPrix]

As of last week (nice and flat ):

 

 

[adam_murphy]

why doesnt your AFR go right down to 11.8? it instead goes down gradually. i think theres more in your car with more tuning. Also do you have a graph that shows rpms and torque?

[AWeb80]

yeah....that done on a mustang dyno?

[Series8217]

1993 3.4 DOHC in an 88 Fiero with a Getrag 282 5-speed.

The graph says "Flywheel horsepower" but we set the correction factor to "1.0" which means no correction, so this is at the wheels.

 

 

The 10ft-lb torque dip corresponds to a bad AFR there; I still have to tune it.

 

Engine details:

1993 3.4 DOHC, balanced and blueprinted...

Ok, more details:

91 Beretta iron flywheel (16 lbs), Sealed Power hypereutectic pistons with coated skirts, balanced rotating assembly, .030" overbore, honed with a torque plate, exhaust valve guides tightened up a bit, opened the bottom ring gaps to prevent flutter, gasket matched the lower intake manifold, custom upper intake manifold (shorter runners, direct shot from the TB to the runners), stock throttle body, stock ECM, stock injectors, stock cam timing, 3" cold air intake with K&N cone filter, 2.5" exhaust with Magnaflow cat and Spintech muffler.

Pic so you can see the intake setup:

Dude, your engine is beautiful.....and that plenum is sweet

 

 

more pics of the build? PLEASE!!!

 

post them in "other cars"

275 WHP and around 250 WTQ (the dyno's wideband was out of calibration, don't pay attention to it)

 

 

 

[jake91]

thats one hell of a cavalier

[Brian P]

that torque curve!!!

[Guest GrandPrixlover1]

does anyone have any idea what my motor would put out? I don't have the money for a dyno run... :-(

 

and I know some of you would tell me it's pointless, but this way I could get at least a "rough" estimate of my engines performance.

 

I'm just running a bone stock 3100 with K&N highflow panel filter and new spark plugs, and wires. Just had a tune up this past summer, and an oil change this past weekend.

[AWeb80]

same as mine

 

~124whp

[Guest GrandPrixlover1]

not bad then I guess...wish I could find an inexpensive way to grab a little more HP though
