Ah, I'll get my car on the dyno to see if my butt is telling me the truth

 

It doesn't help you in the straightline though. In highspeed sweepers then it may help you, but I've never lite up my inside tire on a high speed turn. Maybe if I had the stock suspension and tires this would be a problem though.

 

I'm sorry, did you just say a LSD tranny does not help in straight line performance?

 

I'm sure he meant it doesn't help with the amount of power you N/A VE guys are putting out.

 

right

 

Well the RWD drag guys all use posi/lockers etc.. in their rear ends. And a LSD diffs are more suited to low speed tight turns where the weight of the car is dramaticly shifted to one side, unloading the inside tire(thus transfering more power to that inside tire *on a non-lsd equipped tranny*. ) Having a better suspension would help because the inside tire is less likely to lift off the ground or get as unweighted. But if it didn't help, why did Nissan go to the Helical lsd when they introduced the new 3.5 liter VQ in the maxima?

 

Hey Dave B I need 6 spark plugs and fuel filter for my VE

 

Sure did. LSD in a FWD car is more for turning acceleration, not straightline traction. When you've got over 60% of the weight resting on the front tires peg-leg launches aren't a problem assuming you understand how to launch. I've got over 185wtq and I never peg-leg off the line at the track and I don't hear other guys complaining about it. Also, the LSD in the Maxima is "limited" in that it only transfers a small amount of torque to the non-spinning wheel. I believe it's 30-40% to the non-spinning wheel. The limited label also means that it takes a 1+ seconds to work because the clutches must have some time to mesh and grab because the spinning is what warms up the clutch pack. Launching thru a 60' in FWD on street tires takes around 2.0-2.2 seconds in a Maxima. Waiting 1+ seconds for the LSD to start to work in that time is an eternity. The HLSD and LSD I30s show no better 60 foots than that of an open diff Maxima. For some reason, people think LSD means "locker" differential and that the torque is split perfectly between the drive wheels. Throw these cars on a road course and then you'll probably see some performance differences.

Agreed. I think the reason the HLSD is available is for 3.5 VQ is because all the torque. This car is a lot more suseptable to lighting up it's inside tire when the chassis is unloaded. It may also stop some of the strong torque steer when accelerating hard on uneven surfaces. It doesn't help for the straightline though.

 

I get some torque steer even in my VE now that I have the jwt ecu and mods. Most mags complain about torque steer in the 3.5 maximas not only in the turns but even in a straight line. What is torque steer? It's one wheel overtaking the other. So if you have enough power, LSDs are beneficial. It's also why all the 4-gen guys love to convert to the Canadian lsd. The reason why older maxima lsds probably don't do as much as they could is they are a viscous type. It only "locks" to about 25%. This is probably the reason why Nissan went helical in teh 3.5VQs. To get the "lock" up to about 30-35%. Better traction in the staight line launches/turns/etc....


What you saying about fwd/rwds don't make sense. Both need traction. Either both need it or not.

 

Having owned both LSD and non-LSD VE's and a non LSD VQ, having the LSD helps out alot. There is substanically less unwanted wheel spin and torque steer and much more stable in the rain/snow/ice. Maybe its the amsoil, but it takes less than a second to get both wheels putting power to the ground.

My first maxima didn't have one, and I thought no biggy, it's not so bad, but after owning my 5spd I would never go back.

 

I don't get any torque steer in the straightline, but I do get very mild torque steer if I'm on an uneven surface or in a turn at heavy throttle. It's pretty minimal compared to my old Hondas which would literally yank the wheel out of my hand.


I'd hope for their sake they don't do it because they believe they'll get better 60 foots. I think Neal and Mike have prove that over and over.

All cars need traction, I'm just trying to point out that LSDs aren't these holygrails of straightline traction in a FWD car. The data speaks for itself.

The 04 SRT4 with the LSD is no quicker in the 1/4 mile than the open diff 03 SRT4, but put these cars on a road course and the 04 is about 1.5 seconds quicker because it doesn't melt it's inside tire when boost comes online in the turn.

 

i am going to settle this once and for alll...
the 4th gen is better looking than the 3rd gen and that is what decided it.

 

man just asking for a few answers man mods should stickie this for future refrences

 

Find me a similarily modded VQ and I can settle this debate on video

True, but I'd venture to say that if I had the JWT ECU and/or a better condition engine, I believe my VE would put down 190-195ish whp as well.

I'm not sure what you 4th gen guys know about the VE 'heat soak' but when I dyno'd my car was exihibiting as bad 'heat soak' as I've ever felt in it. I almost wussed out of the dyno as this was at a H-T.com event and I figured I was about to make a fool of myself by putting down 115 whp or something.

I really do believe had I dyno'd under better conditions and/or ECU I could've put down 190ish whp, but then again that's speculation that I cant really hang my hat on

 

VQs heat soak just as bad. I see .2+ and 2mph swings in performance if I don't let my car cool down for 45+ minutes.

I haven't dynoed with my JWT ECU, but this is what I made with the MEVI, Y-pipe, intake, and muffler (81 degree intake temp):



The JWT ECU on average is good for about 8-10whp/wtq at peak. I imagine I should be in the 200-205whp range with 95 octane and my stock sawblades.

Have you ever run your VE at the track?

 

Well there is a simple end to this, that everyone can enjoy. I am heading up to New England Dragway on Friday afternoon. i know 1989MaxMan is a 5speed VE with some ligh modding. i am a 5 speed VQ with I/Y/E. i would live to invite him , if he is interested in showing me the diffrence first hand.

 

Them's fightin' words!

 

Too bad I have a chemistry lab until 6pm... DOH

How about a saturday or sunday test session time 23rd or 24th? It is only another $8.

I havent read the IHRA rules, does a bad muffler need to be fixed b4 racing?

I know a nice straight road in Quincy.... game?

Brian

 

Different strokes for different folks people. If everyone liked the same thing we would all have the same cars in our driveway. all of our houses would look alike etc. etc. Variety is the spice of life. {maximas rule }

 

Quincy, randolph Braintree. take your pic . i would love to see a VE in action

 

OO MEE OO MEE!!! can i go! i'll bring the saab and whoop both your sorry a$$es
i'm owned by inspection sticker on the max (or lack there of for ANOTHER FREAKIN' WEEK!)

 

the more the merrier

 

well just thought i would share that i did make it up to NE drageway last friday and was dissapointed that there were no third gen maximas. in any event i ran a 14.7@93MPH with a 2.2 60ft time. Also i have crappy sumitomo SRIXON4 all season tires. who needs a VLSD when you know how to launch. i also had a bunch of 14.9's and a 14.8@90MPH even thoughi missed 4th gear and rolled over the finish line.

 

Whoa look here, I took my boat out yesterday and look what I missed...

MrGone I live in SoCal: What is winter?

I own both now with almost the exact same mods, one car has more than 100k more miles than the other, so these arguments somewhat tell the truth now to me, but some people are still in denial.

 

I can't say much for the performance of the 3rd gen but the build quality is the best of all Maximas.

 

that bubble butt tree trunk suspension 4th gen?

 

i stand by my observation, the truth is exactly that, the truth.
My car has 110,XXX miles.
ps it has no top end and i don't even try i shifted at 6000rpm in every gear to achieve that 14.7 copies of some of my time slips can be found in the 1/4 mile forums.
have a nice day

 

what are you talking about?
you said 4th gen is better looking...i said not that bubble butt tree trunk in the back. damn you new guys get overly sensitive about your 4th gens.

 

They know more than us

 

what are you talking about lol
i am just bored at work.

 

Did you actually laugh out loud?

 

i do...all the time. mostly because i'm bored, cold and tired so that all makes me dilusional while at work.

 

o quite, you 3rd genners are just mad cause 4th gens look cooler

 

Or perhaps, even, quiet?

 

HUH??? 4th gen cooler?

NO WAY.... I would never buy a 4th gen based on looks, nor on handling.

Perhaps on reliability, but since we are tuning engines, that isnt a consideration for me.

Brian

 

.. but if I had to choose between a 3rd gen and a 4th gen, I'd choose a 4th gen.

 

jeez, everyone has to get his/her two cents into this crap....1st gen ownz all

 

sounds like an excuse to try and make up for one of many short comings.
