Do it man!

I must agree thats A LOT of torque

I knew the #'s on llw boost would be in the 300range, but it looks like it might even push 400's on low boost with a bit more tuning! Simply amazing, nice work SSR!

 

Man .5 liters of displacement makes a big difference.

 

enough with the numbers I want to see a dyno graph!

 

The turbo might do a little bit too.

 

Duh, the average 3.0 liter max makes about 250-280 on stock boost around 6-7 psi. they are making almost 100 more hp from .5 liters.

 

VQ35's have higher compression ratio pistons too, right? That's probably another slight reason.

 

umm if so then why are supras runnin 8:1 and not higher compression. just a thought...

 

What has that got to do with the difference in compression between a 4th Gen and a 5th Gen?

And how many pounds of boost are those Supra's running?

IIRC, the stock CR on a 4th Gen is 10.0:1, and on the VQ35 it is 10.3:1, which would help to yield slightly higher HP numbers on the same comparable boost setting. Add the .5L of displacement difference, and I think it's quite easy to imagine the VQ35 powered vehicles making significantly more power per PSi boost than a 4th Gen (with the same overall setup).

 

The VQ35's compression ratio is 10.3:1
The VQ30's compression ratio is 10.1:1 (possibly 10.0 but same ****)

Thats does definetly effect it, but .2-.3 difference is compression ratio is not going to make a world of a difference.
I think whats making a bigger difference is the extra exhaust being pushed out due to the extra .5L , that combined with variable timing.

True, some supras do run a comp that low. Reason being is so they can run a stupid amount of boost (20+psi) w/o damaging the bottom end. Those blocks are obviously built but 20+psi is still 20+psi. Thats not just a "normal" 20psi either, a lot of those guys have converted over to a single T-60. Those things have a lot of lag, but once you hit 3800-4000rpms the boost comes on, and it comes on HARD. Im talking a jump of about 300-400whp within narrow band of the rpm range. It can be pushing 250who at 4K and be pushing 600whp at 4.5K
It will definetly get the blood flowing thats 4 damn sure.

Unless some1 is planning on running anything over 12psi (safley) on the 3.5 you would need to upgrade the internals. 5.5psi coming from a large turbo is definetly going to be putting out some big torque #'s. 400+whp should be seen with some more dailing in, Even with 5.5-6psi. Thats an impressive # regardless of what car your rolling in.

 

Nice Numbers!!

 

Wow, over 400+whp is insane, wasn't the SC'd Stillen Z pushing 5.5psi on that car?

It is amazing the difference in the Turbo pushing 5.5psi as opposed to an SC pushing the same amount.

Why is it such a difference in the wheel hp in the 2 (Turbo vs SC) when they are both pushing the same psi?

 

Well we knew this car had some midrange but 390 on 6 lbs of boost is just INSANE. I can't wait to see what it'll do on 10 lbs. This may be the ultimate sleeper of all time. Might need to run Mickey's on the street to keep from making a daily vist to the TireRack.

ZO6's be very afraid!

I hope there's enough lag in the turbo so you can drive it daily LOL

 

Becuase the impeller of the supercharger has to compress a higher volume of air to achieve 6 psi than the turbocharger. This is known as efficiency. When air is compressed it heats up, killing horsepower. So the cooler the charge air, the more hp you make, and the less an absent of an intercooler makes a differece....

oh wait I just realized I don't know whether or not this kit has an I/C. Does it?

 

 

Not bad. Have you guys got it tuned yet or are those the final # for 5.5psi? Still very impressive...just curious

 

It's not 5.5 PSI, it starts out at 5.5 then it tappers down to around 4.5 hence the fall off in the top end. We need to get a new wastegate spring

 

I don't have words to describe how fast my ride is now and it's not done yet.
Torque steering is not that bad, I thought it was going to be real bad but it's not.
Traction is the main problem; I just need to relearn how to keep my tires for not spinning. I might go with 255/40/18 or do some minor fender modification and fit wider tires to improve traction.

 

Wow, thats sick. Cant wait to see the final results.

 

why is this in mph instead of rpms? Ive dont think ive ever seen a dynograph like that.

 

Does anyone know what rpm 60 mph is in 4th gear, maximas with 5-speeds? That seems when they hit full boost.

 

i think about 3k rpm IIRC. I am usually in 5th by that speed

 

There was once a product I bought that also claimed to be life-time warranty. Then one day (14 months later) this product malfunctioned and I tried to get it fixed under warranty.... They said that it was life time as long as they made it... but they stoped making it so it voided my warranty. When you mean life time, do you mean forever, or as long as you make it?

sorry for the long question... thanks

 

As long as we are in business.

 

nice #'s..................

 

That still VERY impressive. Even if the peak #'s are at 4.5psi, that means at the crank its got well over 400hp...with less then 5psi being used to acheive that #. Thats nice, I still want to see the #'s with 5.5psi. Im guessing 365-370whp
Nice job guys, very nice.

SSR Im along with Oxidizer2k on this 1, not trying to be an @ss hole but that is a question that needs to be answered. Ive ran into problems like that in the past 2-3weeks with certain compaines while I was at work. I belive I already know the answer, but Im not going to jump the gun here.

edit: SSR I saw the post, that is what I was guessing

 

Nahhhh, you'd have my car up on a lift once a week trying to figure out what the hell I broke each time..... I have bad enough luck with the simple stuff, let alone boost.

 

We could just start stocking axles for you j/k

 

From what I've read the Z SC kit doesn't have an I/C, so it is possible to get more out of it than what they were getting stock.

 

When this kit is ready for the Maximas will you guys be doing installs in your shop? I live in Phx and am always up for a drive to Tucson.

 

We actually will be opening a retail front in Phoenix

Chandler BLVD and I-10ish is the ideal location as it is near one of my houses

 

Will you guys do installs there? When I buy this I want you guys to install it.

 

I can't wait for this to come out for the Maxima. Mustang, Corvette, STI etc. owners all over will be telling their friends, "I got smoked by a Maxima"

 

Very cool stuff...I can't stop following this thread...

 

Of course.

 

Is the boost spiking at the low end? Or could the VIS on the 3.5VQ be set lower? From just the graph it looks like you could lower the Xover another 500rpm or so.

TK

EDIT Ok I just looked at some NA 3.5VQ graphs and it looks about right. They could use the VI crossover a little lower, just that with the insane HP/TQ numbers from the turbo, that little drop before the crossover is made quite a bit larger.

 

Nice.......but automatics need not apply...........You will blow your tranny ! POS Nissan Tranny !

 

WOW,very nice #.

 

kloogy do 6 spd conversion & turbo at the same tims

 

Thats about $12,000 worth of mods right there. Do you think its worth it?
Btw-Id get the alitma 5spd tranny over the max's 6spd. Ite better suited for the power

 

so Guerrero.. hows carlsbad looking out for you? you still think theres a chance you can make it?
