Awesome news guys... 50lb. turbos (effectively a GT30R if I'm not mistaken) making this much power is insane. Just goes to show you that tuning over at GTM is top notch .

Congrats on the new benchmark. Now put another 1,000 miles on it so we can see what happens with another 4-6psi .

well obviously the 4.2 liter engine is way bigger than the supra's, and the Z's typical turbo graph does indeed look nicer but there's no way around it; If you're going to get monster power like 1000+whp, the dyno graph is going to look like a "classic" turbo curve. Even a 1400whp turbo viper's curve looks like a turbo curve where it looks normal for the first half of the powerband, then swooshes up big time all the sudden over a 1000 rpms interval - just look at that june 2006 motor trend article of all the extreme FI'd cars, all the extreme turbo cars have dyno charts that look something like that and they range from 800-1400hp LS2 to viper engine

^^^^
That is true. The curve at those number will always look like you have a turbo curve but of course the low end will be much more usable in the larger displacement motor of the VQ as compared to that of the 2JZ in the Supra.

Well do you really think 1000hp is far from 800? Is an 800HP supra not the same as all other laggy power-banded 1000hp cars? If this car can get a fantastic amount of HP and incredible amount of torque early on, im sure it can after just 200 more hp. And to the people saying you want the power more towards 8k rpm, why wait to have the car wind out to make the power when you can have it faster and earlier and smoother in the rpm scale. I bet this car could give all 900hp supras a run for their money, getting a hell of a jump on them with that kind of powerband. Same reason the new GTR will have a VQ over the highrevving smooth powerbanded RB. Early HP = Early dominance ehhhh if traction isnt a concern....and is this the same car you guys were making AWD or was that a different shop?

Your talking two different things though guys. From a stand still 800whp in a Z is prolly like 1000whp in a supre. But from a roll sometimes have the power up top is what you want. This again all depends on what you want. For a dail street driven car I personally would want the lag as it would make the car slightly more drivable as you would have a bit less trouble with wheel spin because of reduced responsiveness.

Remember that in some forms of racing lag can be your friend. Some racers use lag to their advantage in road racing in order to all them to mash the gas pedal prior to exiting a corner and not get wheel spin and time it just right so that when they straighten out they can hit full boost.

From a highway roll i would probably bet on the supra. The power band on this car starts to fall to much in the uper rpms.

just saying as the numbers get higher, the turbos spool up later and later in the powerband. Sam even commented to me saying he adjusts the gain of the turbos with high hp setups to spool later so that they don't overboost. Look at the 20 psi graph and look at the 18 psi graph. The 20psi starts much later. With 20 psi, the same TT kit is making 400tq at 4000 rpms while the 18psi map is making 400 tq at 3400 rpms. Sooner or later bigger turbos are going to be needed and that's going to move the boost response to happen even higher in the rpms

I'm not making this into a pissing match against supras. I don't care about supras. Just saying with more boost means the curve is going to become more like a classic turbo graph - that's just how it is

Thanks again everyone for the compliments and kinds words, it really means a lot to us and we do appreciate everyons support. We will try to get pics and a video for the next dyno sessions, we were focus on the car and it did not really cross our minds to take pics or video this time, especially at 4 am

At the FPR set to 3 bar ( base pressure with vacuum line disconnected. ) the injectors are at 94% duty cycle at 20psi. Granted we can run higher pressure and lower the duty cycle, also the car was a little on the rich side which would also explain the 94% duty cycle.
