do you have the cam logs with target vs actual? be interesting to see what you are seeing.

Are you having the problem on both intake and exhaust cams?

SP never had a rev-up shop car. They dont do much VQ work to begin with either. GTM never has had shop cars either. Shops were bored with the VQ even before the rev-ups came out. Its just too much work in too little space. Thats why in less than 1 year support/track slips, etc for the GTR has eclipsed every VQ record.

Its the exact same shortblock. There is absolutely no reason a rev-up couldnt make 1000whp. JWT makes big cams and the rest is the same. There's probably less than 10 cars on all the Z/G forums that can make a legitimate 1000whp.

 

I'll get some more logs this weekend when I have a chance.

Just to let everyone know this is my personal car and I still have to pay for everything on it lol.

 

Your personal car is a foggin beast man!

More vids PLEAZE

How's it drive on the street?

 

This. Nice work. And thank you for not posting some bs speed based dyno with no tq curve because the flux capacitor wasn't working blah blah blah... Those numbers look really good down low compared to alot of the higher hp cars on here.

 

Exactly. There have been no RevUp at 1000hp only because nobody that was building for 1000hp happened to have a RevUp. There is no reason the revup cannot do it, adding VTC to the exhaust cams is hardly some sort of crippling of the engines power potential, even if it were you could easily remove it.

**My Personal Opinions** on why there are very few ultra high power 350z/G35;

1; Oil pumps that explode at high RPM. The higher the worse. Typically a 1000hp 6 cylinder is going to be revving to +/- 9000 rpm. VQs cannot do that without a $5,000 dry sump. If you do it anyway, its a time bomb and it risks total loss of every expensive component in the engine.

2; Packaging... its just a huge pain in the *** to do all the plumbing for that in this engine bay. It takes a lot more thought into the fabrication and packaging will still be an issue. Turbos of the proper size for that power dont exactly fit, a few have just happened to cram them in there anyway.

3; open deck aluminum block... nobody knows for sure what it can and cannot take but nobody wants to risk a very expensive build to find out. There is no ultra clear solution as only a few have had luck with sleeved blocks.

4; too many build screw ups... dont ask me why cause i havent had a problem. but for some reason a very high percentage of people assembling these engines just cannot get it right and people are stuck rebuilding more than one just to get the car to drive down the road let alone make high power.

If VQs had a oil pump solution that was $500 or less, and if the stock block/sleeves could handle 1000hp, there would be several more high power VQs out there. Theres probably a decent handful of guys out there that would have a 1000hp 350z right now if all the drama didnt push most people away from this platform within a couple years.

 

I think you hit the nail on the head.

I mean it's kinda sad to see people shy away from this platform for those reasons, but hey I understand it. Also add to the fact that nearly everything for these cars costs more (for the reasons you stated, mainly space confinements). Especially looking at the stock crank strength and the cd009's beefyness... Sad to see that the block is sh*t and oiling is a problem.

I really wish someone made custom iron block castings. I think everyone would be into it actually. I know for some motors forged aluminum blocks can be had for 5k. That's a lot, BUT seeing what most people put into their cars only to see failure again and again around that price would be acceptable. But then you run into issues with the main caps etc...
Or even a full aluminum block, but at least partially closed deck. I definitely investigated half filling my block, might still do that, and looked at possibly welding the top shut, but didn't want to risk it.
Another option is steel blocks, ala TVR speed 12. They get steel and weld it up together and then machine to spec. Kinda ghetto, but those speed 12's are nasty nasty nasty, and if it works for them, it should work for anyone else.

 

The block is fine when sleeved properly as proven by the fact that several 6sec VQ35de powered cars exist now, its just not a cheap platform to deal with. Making power require sacrificing more creature comforts then in other platforms as well.

 

That statement is kind of loaded. I'll agree with you that there are fast cars out there with 'reliable' sleeved blocks, you are proof yourself.
a couple of guys who have posted in this very thread would say the exact opposite about sleeves. I'll be honest I like the idea of darton sleeves, but there's a lot of conflicting evidence. And when you combo in the price, I can understand why a lot of people don't even consider fuxing with them. I mean if someone made a strong block that you could buy and just machine... I think that would give us all a truely bulletproof/fool proof solution.

I'm sure many of the shops who have installed sleeves weren't completely incompetent. One of my local shops is a darton dealer and all their guys (that i've met) know what they are doing. For someone to fock up a procedure given to them by the manufacturer (resulting in component failure) is one thing, but to have so many unrelated installations fail it is highly suspicious.

Nobody makes diapers for vq's, so when they sh*t themselves it's a real mess.

 

In all fairness the oil pump issue is resolved with the Nismo pump if power is to be made at 8k RPMs. And XKRs car is an open deck at 1000whp, not bhp. And in all fairness the N54 and N55 is a open deck even though it's a stock FI motor.

GTM from what I remember was going to attempt 1000whp with a stroked Revup. But that was abandoned?

 

Truth. Someone give me some injectors and I'll try it with 30psi.

Or better yet, someone buy my car and then try it.

 

The nismo pump is the same thing as a rev up pump. Both are 'fine' up to 8k

But as earlier stated most 6 cylinder engines are making power at 9k and up.

2jz can rev to 10k AND make power if you have the head done right. That's another 3k rpm than most people here and a good 2k above even the craziest of builds.
Sorry but GTM doesn't belong in any serious discussion.

Open decks inherently will have more issues than closed decks. Less structural rigidity likely allows for a lower individual cylinder resonance frequency contributing to failure. Also there is less sealing surface area, more prone to head lift...

 

i'd send you my ID2000s i have sitting around. I'd need more pump to make much over 800 on E85. twin walbros on a BAP wont cut it. Gotta go triple or external. Never gonna waste my money on a C16 tune again. Allows alot more power on smaller injectors but I'd neevr run that in the real world. So its not worth the tuners time or my 15$/gal to do it. I'm not even gonna tune 1kwhp for the time being. WOuld rather spend the money/effort to dump this 6 speed for a TH400 with a brake or a 4L80E with a brake. The 0.75 OD on the 4 speed would be great for hwy gas mileage.

 

I didn't know that. Any proof?

 

bc people (Fontana Nissan I think) have tried the nismo pumps and they still busted.

9000 rpm powerband can be replace by using big turbos and nitrous spool. twin 7175 in a STS mount with a 200 spool shot would make 1k easily at low boost on a V6 way under 8000 rpms. but no one has tried it

 

i think one of the FD cars last year actually did do something similar to that. he was running a big single set up with a 200 shoot low end to spool i think he was in the 900's low 1k's with the build. was the team from south africa that pays all out of pocket.

side note they went to a big lemans v8 this year

 

Unfair statements like resmarted pointed out. Comparing a shops drag car to our street cars isnt apples to apples. The differences between a race car and street car, shop car and customer car, shouldnt have to be pointed out.

And in all honesty, Id blow your car the fawk up in an oil change interval...just saying.

Enjoy your set up, every mile, because the other 90% of us sleeved guys arent.

 

How many people had a block or oil pump failure ?

And how many had a spun bearing?

Why would anyone want to run to 9k-10k? Chose you parts right (turbos - cams - stroker- FD) and you can get a really nice power band.

My .2

 

Besides a drysump those engines are more similar to mine and other sleeved setups then you would think.

Anyone can blow a motor up if you try.

 

Just depends on what you are doing with the car. People like Fontana have to abide by Grand Am rules so they make power NA by revving higher. People drag racing on serious setups need the extra rev range to spool bigger turbos and hold gears longer, etc... Everyone does what they need to do to make power with what they are using the car for.


The find the one setup that works in a stock rev limit and makes the most power mentality cant really be applied to everyone.
