Just curious. I've dyno'd mine and was not happy.

 

....thats why i wont dyno my six...i do have a G-tech Pro SS meter tho and i love that for 1/4 mile times, 60 foot and gforces. The horsepower and torque measures are not right tho. It says i have a 140 horse and 180 ftlb of torque. I think thats way to high. Ya MAYBE the motor MIGHT be doing that at the flywheel but no way is that at the back wheels.

 

i dynoed mine

car only put down 268.0 rwhp and 367.6 ftlbs @ 10 psi
with a few issues, we couldnt make dyno pulls past 5,100 rpms

121/153 at the wheels.

 

Jensen, is your car modded?

 

Crate 3.4...



And since the speed sensors will still hooked up, it was backing off fuel and made loop-de-loops

 

Wow thats impressive. You've done some work to your motor. Mine was 117 rwhp and torque was 238 at 5500 rpms. i dint let him go any higher, my car had 142,000 miles on the original block at the time so I didnt push it.

 

Hypertech stage 1 chip, no cat, flowmasher 80, crank & alt pulleys.

So, not really.

 

Boost will do that

 

Yeah you have over 100 more horsepower than stock so I say your doing pretty good

 

The dyno graph I posted above is a customer's car shipped here to FL from VA, it's getting a top end swap, cam, porting, headers/exhaust and tuning. Expecting 225whp N/A...

 

Oh I was talkin about projects car anyways sorry my mistake

 

i didnt dyno my camaro, but i do have a 92 v6 automatic with cold air intake, flowmaster exhaust, gutted cat, msd ignition coil, dist cap and rotor, yand an under drive crank pulley. i didnt dyno it but i did take her to the track. it consistently ran 17.095 at 79.96 mph, now i weight 250 lb and i forget the weight of these cars but i did look it up and i put that in the formula. so when i got home i did the "HP" formula, the one with the ET time and the MPH, after crunching the numbers both formula came out to say that my camaro had 133 hp..not too shabby

 

I've gotten a 17.1 bone stock. I don't put much faith in those ET calculators, I know quite a few people in the low 13's and couple in the low 12's with 275whp or less

 

212hp\232tq with Nitrous but after that run a blown head gasket, i thank cylinder 1# and 3# are done and the motor is tapping but
its not bad for a 150 shot on a 17 year old engine

 

those number seem reli low for a 150 shot

 

well it wasn't a complete test since the motor just craped itself once i hit the button but this was the reading we got before the guy hit the stop button

 

How so? You won't see the full "HP" from the shot at the wheels, and these cars in stock form will dyno about 100whp. ~100whp increase should be expected from a 150 shot

 

I attempted to have mine dynoed last year, but they didn't like where the AFR was at so they shut it down before they got past 3/4 throttle. The dyno was showing 128hp and 192tq to that point though. That's running way lean, 3/4 throttle, and 20° total timing. I need to get a datalog set up so I can fine tune those and figure out the rest of the tune and bring it back for some real numbers. Then I can pull the engine for a rebuild.

 

Thats not bad. I'm not sure why my torque was so high, theres nothing really done to the motor but I havent seen others get anywhere near my torque reading.

 

Do you have the graphical printout that shows it? What I'm wondering is if it downshifted during that run, that would cause the torque to spike.

 

Yeah I'll have to go to my moms, I have it taped to my tool box. It would only down shift if it was auto tranny but I have a five speed.

 

Gearing will skew the dyno results. Stock rear?, and was the final drive ratio on the dyno 1:1?

 

The car is bone stock. I only put a custom intake, and changed the cat to magnaflow, added 9mm plug wires and thats it. Trannys stock, rearends,stock, motors stock with 142,000 miles on it. I run full senthetic but that shouldnt make a difference. Oh and a perf. clutch

 

Do you know what gear it was dyno'd in?

 

Yeah third gear. Is that why?

 

could be. the 1:1 ratio will be had in 4th gear on a manual trans car. youll have a little more torque multiplication in 3rd

 

oh ok, well they asked if I wanted third or fourth gear used I said third. I've never done a dyno test before so.
