Are you guys goin for dyno queen or useable power?

Nick

 

I don't really like that term, as it means different things to different people. In general it would like to state that somehow you can get high numbers on a Dyno but not on the street, right?

I'm not sure how that can "actually" happen, if all the equipment involved is setup propertly, but that is why I want to get on a LOAD BASED dyno as well as a DynoJet.

All I know is that my reported HP from a DTS dyno is "real" power, under load.

I know it's usable, because I can "go" anytime. It's not as if only when I get into 4500+

I have another 60trq at right off the bat. You know torque is what gets the car moving.

I end up with with a total of 100ish something trq through the entire power band, plus another "real" 75/80 HP available all the time and up with about 120HP towards the upper end.

I find this to be "useable".

 

I think he meant are you going for a really high dyno number using 116octane fuel and no ignition retard?

Or are you going for 91 octane and something you can drive on the street safely.

You can add 50-100whp to a car by runnning 116fuel and no timing retard....safely.....that would be my definition of a dyno queen.


Personally, I dont believe in setting up a car to be a dyno queen. I want to max out my car with plane old 93 octane NC fuel.

 

You're right.

I'm hoping that he'll be honest and run pump fuel.

thanks for the note.

Nice kills Alpine. You keep the dream alive. I live vicariously until the APS single turbo arrives this spring. I am pure stock 04 enthusiast.

Man, I am ashamed to talk about my kills compared to yours. Other night, coming home from work, a POS old rusty domestic van keeps coming up and riding my bumper. So I got an opening and punched it and left him behind like a bad habit.

And I am not even remotely interested in him or a rematch…at all. So I finally break away into being all alone on a long straight away of highway. I ease on back down to a comfortable 70 in a 55 in the right lane of a divided 4 lane. Have to be real careful on those next two looooong straight aways cause they are some of the worst radar traps in this area of MD.

Wouldn't you know it. The dipsh*t van breaks away also and comes roarin' up behind me an gets on my bumper again. I don't want to race his rust bucket rag, but get tired of his tailgating and I actually slow down. He starts coming around. I let him get up beside me and notice that he has no hubcaps, natch! A real classy touch if I do say so. Ha. I consider just letting him go by, but I sorta get vibes from his attitude that if I let him pass me, he's gonna be a REAL jerk and pull in front, cut me off, and then slow down. They're real bad about doing this BS in MD. So I blow his dumba$$ into the tall grass again and hope he has learned his lesson and has the dignity to just kinda slink off into the night..

Hell no! Here comes the dipsh*t again! Rust and smoke from his tailpipe flyin’ everywhere. Like when Cool Hand Luke was fighting Drag Line in the movie of the same name, this dipstick, "Keeps comin' back... with nothin’…!" But in his case, nothing was NOT a pretty cool hand! I've nicknamed this guy "Double Wide" by this point, ha. So he comes up again along side and I blow ahead of him again so fast my shockwave probably blisters what scarce little white patches of the original paint that he has left amongst the mostly rust nightmare of his décor.

Well, guys, at this point, I know there is only one way to handle a dumba$$ like this... I punched it and shot out ahead of him and turned off on a hairpin curvy country road that I can optionally take on the last part of my trip home. A real curvy road with hills and a nasty decreasing radius curve that you can see your own tail lights as you go around it.

Now I know if Dudly Dumba$$ follows…his a$$ is grass and I’m gonna be a lawnmower. Ain’t no way he can catch up with pesky curves involved. And I know of many off roads and bifurcations just as curvy in case I run up on slow traffic. I just don’t want to see his eyesore and smoke anymore at this point. He doesn’t follow and I’m soooo glad just to be rid of him. This was not even fun, but there is a reason I’ve mentioned it. Read on…

So, for just such occasions, I have a “Red Neck Horn”. Any of you guys seen them? They featured one on Jay Lenno last Dec. just before Christmas as one of the coolest holiday gifts. You can’t really hear it outside the car unless you roll the windows down. It’s just a little rectangular box that you hold in your hand with a speaker and a BIG red button that you push. Battery powered box with speaker inside is all it really is. When you push the button, a loud mouthed redneck SCREAMS phrases with color metaphors and expletives about !!#@#$!! drivers that you encounter… like my would be racing van from the rusty rusty sewers somewhere underneath hell. You know it screams phrases like, “WHAT THE HELL WAS THAT MANEUVER!!!” “WHAT RACE ARE YOU IN, $HITHEAD” and much worse. My personal favorite is, “SON…OF…AAAAAA…BITCH!!!!!”. You’d have to hear the red neck’s subtle voice inflections to properly appreciate and love it, ha. Makes you feel better after an encounter with a pea brain like the above, anyway.

I kinda wish I’d been (temporarily) sporting that back bumper sticker that says, “If you can’t run with the big dogs…then stay on the porch”. Cause my back bumper and tail lights were all he ever saw. Sheesh. But I can’t exactly run with the big dogs myself yet, don’t want stuff like that on my Z anyway, and bumper stickers of that kind attract the wrong kind of attention from the police.

What can I say… about the van from rustbucket hell. You buy some of ‘em books, and send them off to school and what do they do?!?…They eat the teacher! He got his doors blown in and was too dumb to even realize it or know the difference. I've driven some rattle traps in my time as well. But I was not an obnoxious idiot about it. Anyway, I did what had to be done, but I am not proud of it… But I highly recommend the Red Neck Horn for just such emergencies! Ha Yeah, I feel much better now!! He he. I'll feel even better when I get APS boost!!!

 

Sorry for confusion. I was talking about hooking up since the Z is a relitivily light car. With that kind of power can you go full throttle in anything under 3rd gear and still have traction? Or do you have to go 3/4 throttle in 1st & 2nd.

Nick

 

Defintely wheel spin is a problem, 3/4 throttle at minimum at launch, once rolling, with my new kumho's, I can get through most of second, WOT before it starts slipping again, and all of 3rd, with good surface & warm tires seems to be doing ok.

The problem is at anything there is dirt or broken road surface, wheel spin is a serious problem.

I need wider tires, that's all there is to it.

 

Maybe a new LSD ( Nismo , Cusco etc. ) should help to prevent to much wheelspin

 

LSD won't really do anything about Wheel spin due to HIGH HP, yes it's great for cornering, and getting traction on surface, but 400HP is going to spin with or without LSD.

I believe it comes down more to tiree.

This is what I believe, I could be wrong.

 

I think it could improve traction , if it helps in corners it could help on keeping the wheels locked together when driving in a staight line.
From what I heard the stock viscous dif is pretty weak in keeping the the dif locked when spin occurs.

 

ok, thanks for the info, I may need to re-prioritize the LSD over some other items I was looking into.

 

The guys at Performance Motorsports strongly recomend a aftermarket LSD, they are running a nismo lsd on there silver drag car...

 

LSD's are great for road and drag racing. They help equalize the power between both tires.

The most promising one out there...and I am waiting for its release...is the Quaife gear driven LSD. No clutched or extra noise or clicking. It operates with the smoothness of the stock LSD, and a pefect transfer of power...everytime.

 

This sounds like the right way to go, I was looking for them on the net, I found various resellers, nothing about them directly, and of course the "application guides" don't mention anything about the 350's.

Know anything about pricing for this?

Anything grear driven sounds better than clutches/plates, and not having the nuisance of a locking lsd when you don't want it sounds even better.

 

The Quiafe LSD (I know I am spelling it wrong), is not yet ready for the 350Z. They are doing the R&D right now, and might be several more months before its ready for release. Price will probably be in the $1200-$1500 range. They are more expensive that clutch driven LSD's, but its a phenominal piece of equipment. They also have a lifetime warranty against failure or defects....EVEN IF YOU RACE THEM. I think that is unhead of in the aftermarket parts industry.

If I hear anything more, I will pass it along.

thanks for the thread link!

 

Quaifes are great for road racing and street driving, but they will not work for drag and drift. I know most people don't care about drift, but for a drag car a clutch diff will hold much more torque before breaking. I broke my Quaife with street tires and less than 250 ft/lbs of torques lauching my VW.

I'm speaking from my experience in my front wheel drive VW where I ran a Quaife for over 4 years. It is also less responsive than clutch type for tighter turns such as autocross. I now upgraded to a KAAZ LSD in the VW and it is a completely different feel!

On a side note, if you can order a Quaife from UK direct, it is much cheaper and you don't have to deal with the crappy customer service from Quaife North America (Autotech VW). They overcharged the VW market for years until a competitor (Peloquin) came out with an identical product for half the cost, and now they had to lower there retail price from $1400 to $700! Also they will not waranty many LSD's based on different circumstances... I couldn't get mine warrantied because I did not buy from an authorized dealer (even though the shop I bought it from bought from an authorized dealer). They always seem to find some random reason for voiding waranty's.

 

Lord we are getting off topic. But, hey, the APS kit is already and installed. So...I want a LSD that's good for drag and street, any suggestions?

 

Giovanni...you are wrong about the Quaife for drag racing. It's prefect for drag racing. What is better than a 50/50 split right to left on a start???
