^^^^ Holy crap

that is a huge gain over stock!
do you feel a significant difference?

oh and BTW thanks for all the HARD work your putting in!

370Ztune · 04-01-2009, 05:02 PM

Impressive gains.

wstar · 04-01-2009, 05:50 PM

Awesome

The ricer math just keeps on working against all odds. This car is like magic.

GeneralZod · 04-01-2009, 07:12 PM

Excellent job, it's awesome how stable the line is as well, there is no major dips in it and it looks like power delivery is staying really consistent.

RCZ · 04-01-2009, 07:30 PM

I dont want to say I told you so. Everything comes down to the calibration of the dyno. You will not be able to calculate results for this type of thing, not to mention heat soak makes a HUGE difference in this car. People haven't realized this yet, but I lost as much as 15hp due to a 30 degrees temp difference...

Regardless, those are excellent numbers, congrats on being the first Z on the forums over 300whp. That is simply amazing.

I am going to have the same setup + headers. Hopefully by next week. We will see if I end up making as much power at least.

Really really glad you are on these forums Ben, you are very helpful.

^^freaking awesome!!! these numbers are getting me excited for the route I want to take when I get mine....

Time to get some 1/4 miles times, see if that blue beast can crack a 13 flat with the extra mods...........@110-111 ish would be my guesstimate......

drisko · 04-02-2009, 12:02 AM

THIS IS INSANE!!!! That means (assuming a 15% drivetrain loss) the car is putting out about 380 hp at the flywheel!! And that is without a tune or headers. So, I definitely think 400 flywheel hp is attainable now. Before, I thought it would take some heavy-duty mods to pull that off.

Actually, I *might* already be making 400 hp at the flywheel. Don't forget that right before I did my first dyno, bullitt5897 dyno'd his bone stock 370Z on the exact same DD dyno, and he pulled 254whp. So assuming he has the stock 332hp at the flywheel (i.e., he didn't get a factory dud), getting 254whp on that dyno means we have a whopping 23.5% drivetrain loss on that particular dyno. In order to back-convert 254 to get 332, you have to multiply 254 by 1.307. So...if we apply that muliplier to the 306.4whp I got on that very same dyno yesterday, the math comes out to 400.46 hp at the flywheel!

But don't get too excited. As far as I'm concerned, these calculations make for some interesting conjecture, just some food for thought, nothing more. If someone were to ask me to estimate how much I'm making at the crank, I wouldn't actually feel comfortable telling them 400. I'd rather give a conservative estimate based on, say, 17% drivetrain loss. That'd work out to 369 hp at the flywheel.

Edit: I just realized that I'm being too conservative. If I'm only making 369 at the flywheel, then that means I've only gained 37 hp at the flywheel (from the stock 332). But there's just no way I've only gained 37 hp at the crank, not when I've already gained more than that at the wheels. That's when I remembered that the 17% rule of thumb is for DynoJet numbers, so I shouldn't be applying it to my Dyno Dynamics results. If I do the math against my DynoJet pull of 321.3 whp, it comes out to 387.1 hp at the flywheel. In all honesty, that's probably a lot more realistic, given my results at the wheels thus far.

By my ricer math and yours. the baseline for the other z was 254.2hp wich is a 23% loss from 332 on that dyno to the wheels. If i take 398x23% you get 306.46 Thats what i think your making at the engine/flywheel what ever its called. wich is VERY IMPRESSIVE!

tranceformer · 04-01-2009, 08:44 PM

Are you pulling an April Fools joke on that 306whp DD?

ssqpolo · 04-01-2009, 08:45 PM

OMG!! ricer math ftw with this car. congrats!!

RCZ · 04-01-2009, 08:45 PM

Very very good video. Car sounds amazing too.

How's your gas milage been with the mods added? So far no CES light? And... Have temps risen much quicker than stock in the oil?
