sure
i will find the sheet and post it. Last time i was on it was 377 to the wheels on 18psi this was done at pruven performance in conn. I'm shure they will remember me i dont think anyone in that area had a boosted max at the time.

The numbers seem horribly off turboquake. At 18psi if you are only putting down 377whp then you are probably looking to cause some serious damage cause it looks like its horribly untuned or just horribly built.
I put 15psi on the Maxima on the dyno and put out close to 450whp with no Nitrous. But I also spent in total over $15,000 on the turbo kit and crap. And that was done on a t3/t4 h3 trim turbo.

it sounds like he has a VG30E which is a SOHC 12v motor so it will not make as much power per psi of boost like a DOHC VE or VQ will make
i think the stock Z31 300zx made around 160-170whp @ 7psi (althought non intercooled)
so there not as efficient as the newer high compression nissan V6s

do you have the VG30ET or just a stock VG30E?
stock trans?
what clutch?
whats the fuel setup?
do you have water/acohol injection
who make the turbo system and installed it

this motor is only a vg30e engine 89-94 maxima "single over head cam" only started with 160hp. At the time of that dyno session i went along with a friend to pick up a turbo for his awd eclipse. Didn't plan on dynoing but i put it on to check the air fuel ratio. Six months after that i realized i had a problem with my turbonetics wastegate mark2 leaking, so i swaped it out for a tial car was much more powerful at same boost level. Then i swapped out my blitz electronic boost controll because it was only meant to controll 18psi and was maxed out, it could not hold the boost steady through the gears. Put in the new hks evc and a bigger spearco front mount my injectors are maxed out but i pushed it to 21psi and managed 420whp then i said f*** it and ran 26 but the air fuel dropped off so i called it quits will put in new injectors soon retune then post the new dyno sheet. The 377whp run was about a year after i put the turbo in it was a untuned run/ crude set up (no kit for a 3rd gen) 3 years pass,but now it's all good just need to update the fuel set up. I run 15-18psi on pump gas and 18-26 on race fuel could go with a bigger t3/t4 but i have full boost by 3400 rpm i like that, helps me stay ahead of challengers

i put this car together a few years ago, in my area there were no turbo maximas, so i did not want anyone to copy it so i never opened my hood at the local street races. But now theres turbo maximas everywhere so i guess it don't matter any more so i'll hook up with one of my friends and post pics but pics don't mean shi*** so i am about 1hr from boston any skeptics can send me a pm and i will take you for a ride nuf said.

street racing is 
...
pics may not mean **** to you, but all talk and nothing to back it up don't mean **** to us... would you believe me if i told you my car ran 12.7 @ 109 N/A? Of course you wouldn't; you would want to see proof that i have a slip showing the time...
Like Neal said, we don't need pics of the car (wouldn't hurt though
), just a dyno sheet would suffice most of us.

im calling major BS on this.
here is why
the vg30e-t's get goofy around 18-20 psi. why? even the turbo rods can't handle that. how do i know this? um, i have seen it in person.
you would have lifted the head a long time ago. even the rods in my z are beefier then a vg series and they get funky above 15 psi.
with the air that is moving in that motor as you said that you are. i think you're blowing smoke. vid, engine pics, dyno sheet.

have you heard of pruven performance? He's the guy in sport compact car ultimate street car challenge. He has a 10sec street car and 9sec shop car you can call information and get the # my car was there a couple of years ago, i'm shure he will remember. As for what the motor can take at one point i had 3blocks and 6 heads to play with i could blow the motor on a saturday and be driving sunday night. Yes i blew motors, yes i melted valves, but each time you learn. I didn't care because i could get motors for free or really cheap. As for boost a t3/t4 with a 60trim is not the same cfm as a t3/t4 with a 50trim at 10psi. So if you saw a motor blow up at 13-14 psi or what ever then you saw a motor not tuned well at 13-14psi blow up. The vg30et is 7:8:1 compression, mine is 9:1 so if i can run 15psi on pump fuel 93 octane and your friend can't then someone needs more tuning.

9's? screw that we went for 8's tuning was fine, it was the simple fact of rod tensile strength.
you have given no one ANY proof. i could say i have a 600 hp pathfinder. but you would want proof of that.
or a 300 hp all motor 280z {wait, that ones real too} damn the luck.
all im asking for is proof, not numbers of your turbo size, injectors, or what pruven has in their "shop"

da-max: what i did was get the msd fuel pump booster which raises fuel pressure as the boost rises. I used this as a temporary fix, once the mass air flow meter goes out of range it just uses the last known imput signal in a loop. So with the injectors wide open, my fuel pressure would rise and i could push more fuel with 370's. I did not post this cause it is dangerous if an injector stalls, there goes that cyl. Also since then i have removed the pump booster, it eats fuel pumps, they say it does not. It does i went through 3 pumps in one year. Now i have a nismo fpr with extra fuel pressure, for now i am limited to 17psi max. But i dont care i'll get the new injectors after christmas.

There is no way you were running 370cc injectors at 26psi let alone 17psi. You are way over the 100% DTC on the injectors. Do the simple math on fuel needed and you CANNOT accomplish it with 370s even at 120+psi of fuel pressure. I mean at that point you are straight locked open.

turning off the computer now. But wow you say 26psi and people come out of the wood work to say no. But thats the same thing they said around here when is said i wanted to turbo it in the first place. But i don't know how to post a pic of dyno sheet on the internet, i'll have my friend come over and show me. And i will also look into putting up a live dyno run with pic of my boost gague during the run after christmas. Till then you will have to wait, unless you live in the area and want to go for a ride. Then post yourself, help keep the skeptics at bay. I have one question though is this your way of telling me no maxima has hit 26psi yet..... I thought we had more faith in our cars than this.

big dog you just said it when it hit 100% duty cycle the injectors are wide open. So then my fuel pressure still increases=more fuel not safe but still more fuel!!! My afr on a wide band o2 sensor was 12.5 at 20psi. At 26 it droped off and started to really lean out this was a 4th gear blast with c-16 probly the only reason the engine didn't blow and the water injection running. This car has never gone down the street on more than 23psi. my egt's are at about 900C right so i keep it at 15psi, this past summer when the air is less dense they were about 850. I can hold 15-through 4th not good but i can.

15 psi?
you said 16 jack azz
now, the boost a pump does NOT increase fuel pressure. i have no clue what hole in the ground you pulled that from. but you better put it back.
we ALL have asked for one thing, you can not provide that

And at 120psi fuel pressure, 370cc-->615cc, at 100% duty cycle, 0.6 BSFC, and 15% driveline loss, that's enough to support 498whp. At 100psi fuel pressure, that's enough for 453whp.
Not saying I believe him, but doable with 370cc.

hey,
guys he is no joke he is well respected in rhode island anyone who races in ri knows quake just go into other ri forums and ask around he is well known .he does not lie he does not have to he is just giving information .so why call him a liar do some research and you will see just becouse you cant do it doesnt mean it cant be done .call jim wolf they know him on a first name basis
