Anything else for Hp gains?

Zoren 370

Hi Cell,

OP has already stated on his initial post that he doesn't consider FI which include turbo or supercharging.
But I do agree with you but not on longevity.

I just came upon this at Z1 website. I still wanting to know more about specific Hp gains with this mod.

If taken care of I don't see why it wouldn't last. There are Z within our community with 50K miles on the turbo kit and still running very strong.

I guess its relative to how you drive your Z but most people I know who went to FI they really push the car to its limits and have placed a lot of stress on their motor.
Unless you really change most of the internals of the motor to fit FI.

I mean it would not be so fun to have that huge purchase going FI if you dont drive the beast at redline right? Whats the point of doing FI if you normally drive it as a DD.
Sometimes I do understand to others its just a bragging rights to have one. No pun intended. I do not have any issues with that if anyone can afford it...why not go FI.

Trust me us force induction guys don't baby the car like that. We see redline probably more than the average n/a driver. Phunk is a perfect example from our community. 40k+ miles twin turbo with over 500whp and he beats his car. I believe he has pushed his car over 600 whp already and all on stock internals.

One of the boosted performance guys beat his single turbo car so hard I believe his clutch and flywheel welded together and his motor is still going.

I guess you are right and I would believe you. The people I know who blew their motors I guess has something to do with the tuner. We really don't know what happen. He blew his engine at 65k miles at the odometer.

Nitrous? Not really forced induction, but more of a power adder. Not constant, just when you want it.

Jordo!

Ehhh technically nitrous induction is FI... and doing it right still means a tune that includes extra fueling, colder plugs, reduced timing potentially, etc.

Playing with different fuels and fuel mixtures requires tuning (and possibly different hardware!) too, but a bit more wiggle room in terms of margin for error.

Have any madmen on here played with nitromethane mixtures...?

FWIW, I have two comments on undampened pulleys.

1. So far, I have seen no confirmed evidence of engine failures due to one on a VQ37HR (I know of one "rumored" failure, where the pulley had seized to the crankshaft... bad install? Who knows?). Of course, I am not omniscient.

2. That said, the physics of undampened harmonics correspond to real world additional force exerted on reciprocating engine components. Accordingly, no car manufacturer builds a production motor with an undampened crank pulley that I am aware of. They build the engine with a dampened crank pulley with the specific aim of minimizing the extra stress caused by those harmonics, and the associated torsional and vertical vibration.

Individual results may vary, and some motors may be more susceptible to failure than others with prolonged stress from those forces, but I would say use an undampened crank pulley at your own risk...

EDIT: Oh -- duh -- just the alternator pulley? I guess that's okay if you don't have a powerful amp, but underdriving the alternator on a DD also sounds like a questionable idea, and power gains should be negligible relative to the (more inherently risky) crank pulley replacement.

9 times out of 10, this is the reason. The other 1 time is someone didn't do their homework and cut corners somewhere.
