I just said I was talking out of my arse.


Stock block can't take 600WHP for long

The arse speaks a lot

He said he was talking out his arse but I'm still uncertain if it's true or not... seemed like sarcasm to me.

Thick layer of sarcasm, I don't know who the owner is or what car it is.

600 is a lot, but E85 does help tremendously with pushing the limits. I could safely push my car further with it, but I drive my car everyday and don't want to depend on E85.

Where does everyone get this magical 550whp limit? I would not run my car at 600whp daily but I think it can take it as a hot tune.

I don't recall saying 550 anywhere.

600 is for SURE passing it's limits, also, you don't floor it enough to even overheat your car, so I'd hazard to guess that yes, YOU can get away with a tune like that running it at the limit sparingly, but most of us drive hard, especially those who went FI.


Btw, that 550-ish limit comes from experience. Although it's torque, not HP that kills the motor

This! ^^

Every time I took the Z out, it is going into boost. Have to enjoy it.

Torque is definitely to number. I won't feel comfortable with anything over 400ft-lbs on a dynojet

He's a cool dude he posted it on the 370Z FB page. Cars still going strong. But I also believe that it will only take time until something breaks and needs to be upgraded.

It's part of what we do we gain power. We break something cause of said power. We replace said something with a stronger/upgraded version. And then we add MOAR power! LOL

Just to correct some of you guys. HP is not what limits the longevity of the engine. Its the torque. 500 HP 550HP 600HP.. who cares.. Now say 500 Torque on wheel with stock block then kiss your engine good bye.

TQ was at 551. Just an FYI

Lol, yeah, that thing ain't gonna last E85 or not

Stop being negative Nancy;)

500-530 ft lb here...not one shred of metal. My bearings are surviving and my rods are straight. 2000 and counting, lets hope some of us can redefine the limits of the VQ.

Detonation will kill your engine ages before you over-stress internals. Throwing 11+ psi from anything in a pump gas is detonation inevitably, one hot day, poor components(IAT and fuel temps too high, poor boost control etc) and a bad batch of fuel will kill a 300ft lb car just as fast as a 500ft lb.

While torque is definitely the break limit, the tune can kill any build all the same. Get a great and efficient kit, get topshelf parts, handle the fuel problems and maybe **** wont break with shitty 350ft lb tunes. Just sayin.

But that's just how I think. I enjoy my >500ft lb...not one hitch yet. The oil doesn't lie friend.
