Dyno'd the Z yesterday.. almost stock motor, just have Longtubes, free flowing exhaust, Tune, Underdrive pullies, k&n cold air, 4.10 gears.

293 max HP and 323 Max TQ.
Peak HP was at about 5700-5800 RPM
What you guys think? Not bad I geus, I gotta get my 388 done!!

 

Not bad. How many miles are on it? I had the same thing minus the pullies with 200k and mine put down 298 hp and 340 tq

 

147k on the clock!

 

Nice numbers! Down here in FL, I put the numbers down that are in my sig. Very respectable for your setup and 147k!

 

not bad mine maid 290/330 with longtubes, k&n fipk and catback....curious what it makes now with 1.6s and tune

 

I must have been on a generous dyno. Mine dynod 293/323 as well, no long tubes. Stock manifolds 3" magnaflow y pipe, high flow cat, lm1. tb bypass and the ram air.

 

Different areas of the country
Different dynos
Different results
It would be much easier to run at the track get a baseline by running 3-5 passes, avg. your MPH and race weight..

 

dynojet queens all of you!!!

 

I dynoed too yesterday! Got 296hp and 317tq with 134k on the clock!!

 

Have not dyno'ed or tuned mine yet to see what shes doing. We'll see how she does at the track and I'll decide if I'm happy

 

M6 basterds too lol

 

I dyno'd 286/340 with bolt on's, stock heads and cam with 1.6 rockers and shortie headers and a dyno tune.

 

Dynos are gay. Go to the track and post your times if you want to think your car is making power

 

amen

my dyno numbers r in my sig but what are my track times

 

I made 295/323 on a dyno-dynamics dyno through an A-4 w/3.23's

 

Just came back from dyno again with the added 1.6s and baseline tune(which is still rich) as you will see when I post the graph tonight...
But made 310/343 up 20/13 from last time

 

Dynos are great for tuning purposes
When a dyno can give me a TIME SLIPi will shut up!

The Track is the only way to see if that power is working. Get the car weighed then get the MPH that will give you your most accurate reading...

 

^^^ amen

 

Last time I dyno'd (2000'ish ?) the LT1 made 323rwhp/343rwtq; on one occasion I made 330/350, but don't typically choose to state that as the real dyno numbers. Full bolt-on, everything you can possibly do that I'm aware of on LT1's? My ET is in the sig and that was also 2000ish when I made that run. I believe my car to be a full weight WS6 T/A, my guess is somewhere in the 3500 ish range. At the time I ran the 12.61 @ 109 I was missing a few minor bolt-ons, but I think the car could go 110+ on a good day with bolt-ons. I don't know if my ET will go much lower than the 12.40'ish range at my current weight (still 3500'ish).


OP: nice numbers on your Z

 

Im still missing: TB, AIRFOIL, EWP, UD Pullies, and a good catback lol still have the American BLunder flowstopper
