thats about as valid of a question as saying "can I launch my Z into space?"

Matt

 

I'm sure it can be done.. dont get discouraged by the posts. People were saying 400whp wasn't reliable on the stock engine and now its 500whp.. it will take money and a LOT of practice. You can have a very powerful car but you need a driver that can get it down the track.

 

My first suggestion is sabotage! If that doesn't work...

Build your own turbo setup...

Get an SGP LONG Block + Darton Sleves ($+2200 is what I was quoted.)

If you only need to beat them once... don't bother with Cryo treating... But if you do there is an outfit in Austin texas, near SGP. (Checked on that myself)

The turbo setup would have to be custom because the larger turbos you would need to run, and you would probably need to model the placement similar to the 8 second one.

Start with a Base model, so you can go RaceLogic + Quaife. Cheaper...

Strip a lot of weight... Get a roll cage, you'll need it. Remove the stock ECU and use the AEM. To do that you'll have to remove the fly by wire, hook up your own throttle control. Run 1100cc injectors, with a custom fuel rail. You may want water/meth injection...

Upgrade the suspension a lot or they will kill you in the corners. Get a fuel cell... Oh the list goes on and on...

Or buy a GTM from factory five, drop an LS6 in it, and super charge it... 2250lbs same engine... That will beat them... and it would cost a LOT less.

*There is NO replacement for displacement.* The VQ35 will get to 1000 HP, but it will never be as easy as other methods...

 

AEM does not have an EMS out for the Z and has halted any plans on doing so in the foreseable future...

the guy never mentioned cornering, just going faster than 10 sec 1/4 mile

 

APS has a Z making 742whp.. is that good enough for a 10 second pass? possibly.. and that is without stroking the engine

 

It can be done. It will cost you around $60-70K on top of the car to do it properly and maintain some shred of reliability. And I still maintain that 400whp is unreliable on the stock motor. All depends on what percentage of failure you are willing to accept as "reliable".

 

Kinda hard to tell someone what they need to get to the 10's in their 350Z...since only one 350Z with a VQ35DE has done it, so far.

I'll try to recommend everything I can think of that you'll need though..

Drivetrain

If manual:
ATS Carbon LSD
ATS Triple-Plate Carbon Clutch & Flywheel
Driveshaft Shop Level 5 Rear Axles
B&M Short Shifter
350EVO 3.9 Gear Set

If automatic:
ATS Carbon LSD
Driveshaft Shop Level 5 Rear Axles
350EVO 3.9 Gear Set
SGP Racing-built 5AT (valve body upgrade, tq converter, etc.)

Engine
H-Beam Connecting Rods, I suggest Pauter.
Extreme-Duty Pistons, I suggest Arias (8.6:1 compression ratio, .040 overbore)
Darton M.I.D. Sleeves
KJR Performance Crankshaft Pulley
Ferrea 1mm oversize Valvetrain Kit (+port and polish)
Tomei 268 duration Camshafts
APS Intake Manifold (not out yet, this is not the upper plenum)
Koyo Radiator
NISMO low-temp. thermostat
Stillen oil cooler
Stillen power steering cooler

Turbocharger Kit
GReddy TT kit +FMIC + GReddy 20G wheel on the 18Gs.would work. You have a few options with this, it's pretty much up to you. Personally, i'd either do a GReddy tt kit + fmic + greddy 20g turbos or Speed Force Racing tt kit + fmic + garrett gt35 turbos.
MoTeC M600 standalone engine management from Nizpro
Return Fuel System (AAM works)
Walbro 255lph In-Tank Fuel Pump
RC-Engineering 750 or 850cc fuel injectors

That's pretty much it (yeah, not so much, eh? ).

A great tuner, great installations, and 295 or 305 rear tires also helps.

 

Which is why he said switch over to throttle-by-cable, which, in that case, an AEM EMS would work alot easier.

I agree, no need to include all of that.

 

for as much money you are going to spend on it just get a dif car

 

Not sure why everyone immediately recommends the AEBS stroker kit when wanting high horsepower...the 1400hp 8 second 350Z with a VQ35DE isn't even stroked.

 

Keep in mind that there is a 430rwhp APS TT 350Z, stock motor, few bolt-ons, that ran 11.60 with slicks.

10's are VERY possible with the right setup, and most of all, A GOOD DRIVER (practice, practice, practice!).

 

nis350ztt,

so you actually recommend the 3.9 gears for FI then? I guess cause the car will have some really wide slicks that those gears would work ok then?

 

Well, the 3.9 gears would help with acceleration, which is all he needs the car for.

If it is a daily driver, I don't recommend the 3.9 gears, I would stick to what is in the OEM rear end (3.3 if 5AT or 3.5 if 6mt).

 

So far people with big FI and even the 3.5 gears are having traction problems

A lot have been switching to 3.3 gears, not higher

One guy with over 440whp on the APS kit had the 3.9 gears and said they were horrible with that much power. That he spent more time spinning tires and shifting than when he went to the 3.5 gears.

So it seems that traction and a raised rev limiter is a big issue

 

Consider what you are basing these "traction problems" off of...2 350Zs?

None of them are going to be doing mainly drag racing either, though.

You shouldn't be spinning the tires any more with 3.9 gears than 3.5s.

Also keep in mind that none of them are using the axles + lsd. (and what size tires did they have?)

If that isn't enough, i'm sure RaceLogic's TCS would work. I'm strongly considering getting it.

 

I'm basing this off of I don't even know how many Z's - yeah most of them are set up more as a show car with bragging rights than a real performance oriented car, but still Almost everyone I've ever talked with high hp and most articles online or magazine with who has FI has said they have traction problems. Or there at least seems to be this 12.3 sec threshold where no one can get faster than 12.3 sec with street tires no matter how much more hp they have because the car just won't hook up and will spin out the tires in each gear all the way up until 4th gear in some cases

Doesn't it seem rediculous that the new Z06 with around 430 whp is able to do 11.6 1/4 mile in stock form but a 550whp 350Z can only be a little faster at 11.3 sec if it has racing tires? Otherwise it's doing like 12.1 or 12.2 on street tires

The ford GT does around 11.6 sec too

So does the viper

The GT is rear engine so it's just going to have traction. The viper has 345mm tires in the rear. The Z06 has the transmission in the rear and all sorts of carbon fiber parts up front to reduce the weight up front and orient it more towards the rear - along with 325mm tires

The Z has nothing like that going for it

 

IRS doesn't help the 350Z launch better either. Doesn't the Z06 have an IRS setup as well though?

I think in a few years the 350Z will be dominating the current fastest Supras, running 550rwhp, standalone, OEM engine. We'll see though, it's just a matter of time.

BTW, the Z has great TQ response, that is just one thing it has going for it.

Another BTW, don't put too much into these times...over time we'll see some drivers that are more focused on the drag track and we'll see what these 350Zs can really do. Alberto is one guy to watch, he's getting a Turbonetics ST, i'd check the drag forums for a thread with his times. He was near high 12's with only a few mods and drag radials while N/A. Very good driver, and he's just one of them. BriGuyMax is very good at driving, he's getting an APS TT installed. 90% of drag racing is driving and I feel like alot of the people that post their poor times seem to forget that and blame it on the car's traction. It's kind of like the blown motor threads...tons of people believe the 350Z can't take almost any boost because of all of these people that posted their threads and posted something about the VQ35DE rods being weak and etc. when there are so many other variables that come into play that they would rather not account for. (i'm not pointing any fingers...but if they were a little more educated on f/i they would realize this)

 

[QUOTE=nis350ztt]
I don't necessarily believe every magazine I read, but it does make you wonder when 90% of people beyond 450whp say their FI Z with good wide street tires and LSD can't get traction. Just like you said - JAson@MRC Motorsports doing a 11.60 with slicks and 430whp - there's the proof. Let's see him do that time WITHOUT slicks. The Z06 can do it in stock form without slicks.

I think Phunk did a 11.3 with around 550whp but my numbers might be slightly off. Talk to him though. He's raced the 1/4 mile with 522whp at one point.

The car just sucks at launching, plain and simple. It's fine from a roll (hence being better on a road course), but that's not how drag racing works

I'm sure the Z might eventually be capable of making high hp like the supra, but the supra I think has room in the back for bigger tires than the Z, it also has less aggressive gearing, comes from the factory with a turbo already on and still has a 53/47 weight distribution, and has an inline 6 cast iron engine instead of a V6 alluminum engine - big difference when it comes to making boost and not spending TONS of cash. Again a case where the Z can be made to be really fast, but is it worth it? A 300ZXtt would be the Z for that job, not the 350.

I agree though, the best stuff is yet to come. The 350 is just now starting to mature

 

[QUOTE=sentry65]For sure, prices will go down and will be similar to what MK4TT prices are now.

 

just for the record... my first and only time out on the built motor was at 522rwhp, 11psi... and i ran 11.6 with not very good driving, too low of a rev limiter making me have to shift into 5th just before end (costing me an easy .2-.3), and traction issues on 18" drag radials. the power was there to go 11.0-11.2 if you ask me... if i had slicks and coulda just DROPPED it and my rev limiter was at like 7400, and i was shifting without letting off, i dont see why not.

I think 550rwhp can put the 350z into the difficult 10s, and 650+ should be pretty easy 10s if you can just hook up. When driving around in my Z at 14 psi, seeing how it goes when i race other cars, and how it feels, there is no doubt in my mind its a 10 second car if someone put it down the track right.

BTW, you couldnt pay me to put a 3.9 in my Z.
