The hr is the same motor as the vhr? That doesn't sound right at all. In addition to the displacement increase, its a lot stouter internally. Not to mention VVEL.

My bone stock motor 370Z, with a Stillen SC kit, cat back exhaust and tuning does 453/337@ the wheels.
It's step by step well documented in DSPORT magazine.

Sorry to say but that's where you will be stuck at for the lifetime of that kit, no matter what you do. In my opinion, if you are limited due to the configuration of the kit and there is no room for growth, then its terrible.

I didn't mean the EXACT same. I know the differences between the two. But should those differences cause that low of a put out? Nope. Not at all.

I very well know the kit limitations and the stock engine limitations too.
If I want more power I built the motor, then I'm going TT, not a brainer there and can easily attain 700/800RWHP.
However that's not my interest at this point.
All I did was answer your post about the 400HP with a Stillen kit with built motor, however you'd been talking about a 350 motor.

So? My point is that it's still making horrible numbers for what's done to it. It's not making the advertised numbers it should be now is it?

Could we have a link?

So my dealer here offered me the info gauge by Greddy. It cost about as much after customs as the AFR gauge from gtm. The info gauge connects directly to the OBD and you have the ability to connect to the info gauge external sensors as well. A couple questions: 1. What can be checked through the OBD? 2. AFR, oil pressure, AT temp, etc. 3. If so are these readings accurate? 4. Does the car have a wide band?

thanks

Bart

Oh sorry. When you said it was the same motor, i assumed that's what you meant. I didn't realize you meant "It's the same other than all of the differences."

I wouldn't trust the factory O2 sensors. I have a separate wideband. And boost won't be picked up through the OBD port. By the time you add the additional sensors to the Greddy, it's likely you're over the cost of the standalone gauges.

Shamrock · 11-19-2013, 07:57 AM

Could someone explain to me what the wideband means

thanks

Bart

Chuck33079 · 11-19-2013, 08:03 AM

A wideband oxygen sensor is a type of O2 sensor. You use it with AFR gauges because it is accurate enough to give you meaningful readings.

Sure, it means you probably should never buy aftermarket forced induction for your car.

OP, before you do this to yourself and your car, it may be really helpful to order Corky Bell's book on supercharging. It's called Supercharged!.

His book on turbos is good reading too.

This guy has clearly not done his homework.

Thanks for all your informative info so far "elperuanal?" Everyone else has been awesome. I guess there always has to be the first poker.

Guys,
Is the band on the car a narrow-band or a wide-band?

thanks

Bart
