Default Guess the RWHP!

My Z51 is going to get a kit installed at the masters (A&A home shop) themselves. 750 miles away!
My tuner is on a major build and has vacation for 2 weeks.
So it was a no brainer to let them do it!
Plus it sounds like they want photos of the install
for the install manual.

This coming week on the 16th-18th.

Stock Z51 7 speed with open NPP!
with complete A&A kit with V-3si blower.
I will post the dyno sheet when I get it. Likely
Friday!

No headers! I know what number the same car made there but that wouldn't be fair!

I will say 570 RWHP. Picking mine up today. I'm hoping for 570 to 600 for mine.
ECS
AR 1 7/8 headers

567 is my guess

Is there any reason everyone is going conservative on their boosted cars? I don't recall anyone having over 600 on their own personal car. I've seen shops way over that but none on a DD car. If I ever get mine installed I won't take anything less than 625.

so say its 570, what numbers are you at the flywheel 625? I guess my question is will these supercharge kits be equivalent to the new zo6/7 coming out or would the car require more work then headers, tune, SC to make it a sleeper and beat the new z06

Blower only these cars will do right at 600whp on 93 octane, no problem if you lean on it a little.

So that alone will be faster than the new Z.

Add headers and meth injection and you are well north of 700whp all day long.

It's a combo of bad gas concerns and limiting liability.

On reliable 93 gas, you can do 625 all day long on 8psi. The problem comes in when you get a bad tank.

It's critical to use Torco, or just jump to methanol if you're looking to go 600 or better. Tune/boost/engine isn't the problem, it's the crap gas with MTBE, etc.

Nice HP spike at the end. I'm wondering why your torque is so low. Nice numbers.

This only a 3.8 pulley also no headers on 91 octane. Showing the efficiency of the si trim! Can you post your sheet up?

Should say if those are SAE smoothing 5
if not they could be showing higher. That part is not showing on yours!
If it is smoothing 5 and SAE
It's the product of the smaller pulley and the restrictor plate.
It bringing's up the TQ while holding down the hp.
It seems it would have some cost somewhere. Seems looking your TQ past 5250 RWTQ at 6k has fallen off faster and is
below mine.
Way happy with the numbers I have even more with the way it screams.
The first few hundred miles I got to play some and it pulls hard.

Very glad you are happy with the results. I told Andy on Friday it should make between 575-600rwhp! Looks like we hit it right on the noise. Enjoy that sweet street car.
