My L99 Dynoed 405hp/410tq w/ TSP 1 7/8 and TSP CAI



2 runs on a dynomite, 397hp/410tq~ and 405hp/410tq~ SAE was about 396 I believe.

Mods:
Weathered 100,000 mile tsp 1 7/8 headers, offroad extensions
Magnaflow 2.5" resonated x pipe paired with a muffler delete that has crushed bends (not mandrel)
Tsp cold air intake (the black one) with a fresh k&n 4" cone
120,xxx miles
93 octane
Rickifast tuned from unlimited performance in Corpus Christi Texas
Stock pulley, tb, intake, heads, plugs, wires, trans, rotors, thermo.
78 degrees, unknown DA

Not bad for a car that was left for dead at the dealership when I bought it.
Car ran a 12.6.. On stock bald pirellis.. Leaving off idle with traction control before the magnaflow and muffler delete.

Very happy with the results.

That's why I posted up et's for comparison.

Numbers don't mean anything.

That's true. Most likely it's in the 370 range on a dynojet. 12.6 isn't bad with no tune.

318-323 on my Dynojet

Looks like the op did not pre Dyno for comparison sake.

I'm sure he is happy that's all that matters anyway.

Oh no that was with a tune, it was leaving off idle, not stalling up.

I trapped pretty good tho, I forgot what it was but it was like 112-114 ill have to get back to you on that (off the top of my head) The 60' was 2.0-2.1 spinning it's ass off.

I've got a dynomite 10 minutes from my house. I go 30-45 minutes down the road to use a dynocom and a dynojet. The last time I was on a dynomite was probably 2001 when it was installed.

I use a land n sea dynamite to tune my car on. I have never seen a graph as rough as yours. That spike isn't true peak. When a graph is wavy like that the numbers are skewed. I'd say you are 370-380. Any spark knock? That's what it looks like.

Also that graph is observed power. Have him open the file and change it to std or sae. It will probably drop.

I'll tell you that Dynomite dyno is pretty accurate maybe a little conservative. With a CAI inc intake, custom catback mine dynod at 325 SAE corrected. After tuning it pulled 348.2 sae corrected 366 uncorrected. Same exact dyno as the op.

I asked the same question, my tuner didn't hook up his hp tuners to observe the tables. It appears to be knock but I wouldn't know, my tuner only did a wot street tune

I need to get it looked at, but the 397 graph and the 405 are very identical. I'll upload that one later after the gym

I am the Tuner at Unlimited. We use a Dynomite Dyno and were having a Dyno Day this past Sat when the OP had his car dyno'd. Why the graph Spiked like that on his car Im not sure. Could have been knock or lost Communication with the Tach Signal. I'd say smoothed out the Car would make around 380 Which is still very impressive for a L99 Car. If the OP would like I will put the car back on the Dyno and monitor the Knock Sensors as well as check the plugs wires for the Tach Signal to see if we cant get a better looking graph/Pull. Let me know sir.

Typically on our dyno a L99 Stock puts down between 320-335. Manual LS3 Cars around 350-360. Usually we use SAE numbers but for the Dyno Day some people requested Observed numbers and some SAE.
