Anyone know? I googled and searched the board and there really isn't a consensus on what the '09, '10, and '11 ZR1 are putting to the wheels.

YWZ08

I've seen 505-530 RWHP don't remember the torque though.

Thats probably mustang dyno numbers or very conservitaive most dynojets are more in the 540-560 range if you go to LPE site they have a baseline (and I would figure they would want baseline as low as possible so their mod's look better) compared to a stage 1 and their baseling pull was 558.48 rwhp and 532.96 rwtq.

Looking at my dyno# from last week 541.31--------525.37t

Guy's, I forgot I have a filter in mine!

427500

I have seen 517 hp. 500 tq. in an article in Vette magazine, seems low to me.

VegasZR1

Mine was 547 HP and 535 Torque and after the LPE stage II it was 600 HP and 602 Torque. These numbers where on a Dynojet.

DoctorV8

Mine made 541/530 on a Land and Sea dyno at England Green. Their dyno puts out numbers virtually identical to a dynojet.

540-550rwhp and 530ish rwtq sounds reasonable, but that's still an 90hp loss from the crank to the wheels. The Z06 only seems to be losing 45 or so and the LS3 about 50.

What's the 30 additional loss of ponies on the ZR1 between crank and wheel caused by? Anyone know? Is it the beefier diff, driveshaft, gears, wheels/tires?!?!

Kyle Lemish

Most stock Z06's that I have personally seen on dynos are in the low 440 range and 412-417 on torque. I have personally had 2 different stock Z's dynoed and thats where they fell on 2 different dyno jets.

I will have my ZR1 done here in a few weeks.

So the Z06 may have a tiny loss advantage: Could mainly be the ZR1 clutch

505x.85= 429.25
638x.85= 542.30

1 BAD ZR1

On a Dynojet my stock HP number was 535rwhp at 50 degree ambiant temp. I don't recall what the torque was though.

I have a stock ZR1 dyno graph displayed in my article here:

540 rwhp and 529 tq.

I have seen any where from a low of 505 rwhp to a high of 565 rwhp stock. I am sure the real power output difference per engine is only a few %. The ZR1 has some disavantages on a chassis dyno. You don't get the proper air flow for the intercooler heat exchanger and the SAE correction factor can sometimes over correct for high barometric pressure for a supercharged engine. The SAE correction factors were developed for NA engines.

On our Mustang dyno we typically see 515-520rwhp and 490-495rwtq
as a baseline and about 565-570rwhp and 520-525 rwtq. after tuning.

04_Z06_CE

Its cause Zr1 is overrated...Meaning the HP numbers..should be like 600 crank hp

1 BAD ZR1

638 crank HP is correct. If you do the math (638-15% for driveline) you get 542 rwhp.

Kyle Lemish

yea cause these over rated cars are running 133++ traps all day long in the 1/4

3 Z06ZR1

Tune only making 50 rwhp?

DebRedZR1

Feel better? Now please take your AV attitude back over to Z06

Must be one h**l of a tune because LPE only getting that with a pulley and tune?

0Steve@Vector

I've tuned a car for a member here, I guess ask him.

Our tune maximizes the factory pulley configuration, In doing this we've seen another 1.5 lbs of boost. I believe this car had some miles on it so I'm sure he knows how it felt before I tuned it
