Are our engines for the most part, indestructible, or has someone had the ***** to intentionally abuse these motors to the point of destruction?

 

HlH blew his intake manifold, I just can't remember which peak #'s he put down though, IIRC 500fwhp/550fwtq? or was it more? Did he have a UDSM or MEVI?

The block itself is very strong, the internals are doing alot better than what people have originally though years ago when they just started to boost.

 

he had a MEVI.

 

indestructible? not hardly. no one has found a big breaking point yet. Just stay posted. Hal will.

 

I know Matthel has tanked a few motors and so has Hal, no motor is indestructable.

 

I know trannys are very easily destructible.
As far as the motor...it was built very well. But who knows how much power it can handle...

 

krismax did a number on his with his 8k red line (and like 200K miles). I dont know the details but i believe the oil pump could not support revs that high.

 

What are you guys talking about? Go over to the boosted forums. Someone posts about a blown motor almost every week. Turbo95Max has blown 4 motors in 4 years. Hal blew at least one. Yes, they push the limits, but there a tons of other people here who have blown motors one way or another.

 

It's all in tuning.

No motor is indestructible.

I have blown multiple VQ30's, but largely due to stock timing and starving them of fuel.

Now with that fixed and I can't seem to blow it up (knock on wood), even at 20psi.
It dynoed over 500whp and 600wtq at 13-14psi.

The VQ35 I believe has weaker rods? It seems as though the Z guys are having problems even in the 4xx's with claimed "good tunes"

 

I sure wish it was indestructable, mine is still running strong and hope it does when I put it under 9lbs of boost, nothing too fancing, just enough to embarass that stupid pony on the front.

I guess since were all pretty knowlegeble on here and take good care of our cars we catch signs early and get them repaired.

Now I dont know how you guys are holding up 500fwhp but thats justs sick, I would be deathly affraid of spinning the planet the other way.

 

I've gone through 2 motors - first one due to hydrolocking

The second - i believe I had a weak ring land in cylinder 6 to begin with. 16 lbs of boost took its toll eventually.

I'm on my 3rd motor now. I've added injectors, a wideband and will soon be installing equipment to adjust timing. I'm running 16 lbs boost on the street and plan on cranking it up a tad more at the track....

 

Thank you for taking the word right out of my mouth

If the A/F ratio isnt balanced out, doesnt matter what motor you got, its not going to last too long if your making any kind or power.

 

It will pop next week after I post this, but I'm still on my original stock motor

 

If I'm not mistaken his motor was on its way out before that.

 

It's a piece of machinery and over time, all machines without proper maintenance and care will fail.

 

Does anyone know if the vq30de can go 600whp on the stock bottom end without blowing up? I'm pretty sure Hal is almost there....but anyone else wanna input on this?

 

drop it in second hard at 100 mph and see what breaks.

 

sounds like some of you guys really push your VQ's to the limits. About the VQ35, and hlh mentioned the rods being weaker on this engine, did Nissan cut some more corners when designing the VQ35?

 

bigdogjonx knows but he's moved on to real cars soooo....

 

if you drop it in 2nd only transmission going to break

 

I did that once.... Forgot that 4th was straight down from 3rd. As soon as I heard the revs go up I looked at the tac and pushed in the clutch. I saw 8000 RPM.

30 000 miles later all is still well. (though I know that my anecdote is not representative of continual abuse / boost.)

 

Nissan didn't cut CORNERS they cut WEIGHT! They trimmed a huge amount of "fat" from the engine internals. The result is a much lighter, rev-happy engine. The consequence, however, is that it can't handle the abuses of boost as well. But a 350Z would be fast enough for my liking, especially with a few minor mods, so I wouldn't be complaining!

 

Prove it. Have you had this experience before? I know of several people who have ****ed up their motors this way and their transmissions run strong.

 

Along with the engine, once you let out the clutch


Try it... it's great! (not speaking from experience of course )

 

Vq30 rods and pistons are lighter than 3.5

 

I never seen tranny break but ummmm
