Thanks Rockland for the insight on the previous post regarding con rods-it is appreciated. Piston slap, offset crank pins-where do these guys come up with this stuff? I can remember when the light clicked on for me, the day that I realized that I didn't know everything and in fact knew very little. That is the day I officially started learning. Unfortunately, people put forth much more effort convincing others of their knowledge than actually obtaining it. For the record-Rod failure is caused by tension loads (rpm), extreme compression loads (detonation or extremely high power levels) or fatigue cycle life (extended operation near fatigue). Since none of the other situations were present-we must suspect detonation as the culprit, but will perform a post mortem to see if there is any evidence. The 1NZFE rods do not fail by design, neither did the Honda rods or small block Ford rods or any of the many powdered metal production rods-the culprit has almost always been a tuning error. There is a limit to the power production with the production rods, but since (in the case of this yaris) we were nowhere near that absolute power limit

so explain this:
on a stock engine, stock ecu, intake, exhaust, bone dry day (so dont' even say it was hydrolock) at 85mph (over 4300rpm) about 80F ambient temperature, engine had 47,000 miles on it. the 1NZ is not designed to rev above 4000rpm for extended periods of time. |

a video of a car that could rape you in its sleep, on tires 50mm wider than you'll ever be able to run, with twice the power you'll ever see is worse than spaghetti and bendy ends.. that you could build from home depot or hrpworld.com for around $12... at least it's shiney with a cool sticker on it (no offense to you Garm) |

No worries about the intake situation--and I respect people having and voicing their opinion(this is what makes America great). I just wish they would not be so quick to draw absolute conclusions from such small samples (the equivalent of automotive bigotry). One or even two damaged con rods does not mean all NZFE rods are bad. Honda guys thought this too, but since I ran stock B16s in endurance racing where we ran 8200 rpm for 24 hours, not to mention producing over 500 hp in turbo form, I'd say the weak con rod theory was just that. FYI-Engine testing at the OEM level includes running the motor for 24 hour periods and ranging the engine speed from peak torque to peak horsepower. This is done at 1/4 throttle, 1/2 throttle, 3/4 throttle and then at WOT to endurance test the reciprocating assembly. I personally have run my Yaris in 4th gear from Vegas to So Cal and back (mileage testing for my book) and run it flat out 114 mph for almost 9 straight miles. This combined with the hundreds of dyno tests run to the rev limiter under WOT shows me that (as has been their history) Toyota over and not underbuilds their vehicles.

With previous dyno runs with bigger intake manifolds and throttle bodys without more displaement, more cam, or forced induction a higher flowing intake will offer very little gain and may loose h.p /torque until very high rpm.
What calculations are you using for runner diameter and length. |

can't wait for my manifold!

The only way I could see a great manifold not being continued is if it costs more to make than what the market is willing to pay.
