everytime I race this 94' 3rd gen SE 5spd...I only walk on him....what is going on?

I am a 5spd as well...my clutch is slipping, but only @ shifts @ redline....so it's not that bad...I think my flywheel is warped as well....could that cause any performance loss or acceleration loss?

I have a y pipe, high flow cat, b pipe (all mandrel bent), high flow muffler....
new O2 sensors, new knock sensor, absolutely no codes!! new pcv valve, new tranny fluid, synthetic mobil 1 10W30 oil, my timing chain tensioner is going and my differential bearings are not the best....probably totally unrelated, TS ecu, and frankencar intake with apexi dry filter, new fuel filter....I even have the mevi and a short throw shifter...I know I will get flamed for this, but all the other 4th gens with 5 spds with these mods are running low 14's consistently if not 14 flat....I basically have everything but headers, cams, and flywheel...I have changed every fluid

the 94' SE only has a straight pipe in place of the cat and a CAI....
we never go off the line...we always go from a roll....and I only walk on him....impressive how fast a '94 5spd is!!! I do roll with about 100 lbs of stuff in my trunk...but that shouldn't matter that much...

maybe I just need to dyno and see what's up...lol...this is crazy...he has spent almost nothing on his car and he hangs with me...I have every NA mod concievable almost and struggle to pull away from him...

 

That's definately strange. Get to a track or on a dyno. Track preferably.

 

so I'm not crazy right? lol

 

by the way, I forgot to put in there that I have new spark plugs and my TB is as clean as it could get....oh yeah, and a udp...all of which the 3rd gen doesn't have!

 

I don't find this weird at all...the '94 SE, I assume with the VE30de?...has 190hp just like the VQ30de. The '94 is also lighter. Why is this so far-fetched?

:dunno:

 

If the 3-gen gets a Y pipe, then it will be even. I raced a stock 4-gen with my modded old 3-gen and I would walk HIM after mid-3rd gear. The VE30DE's VTCs and varible intake really let's that engine breath vs the 4-gen VQ.

 

D'oh...the VE30de...not VG. How do you keep those distinguished?

 

Easy. One is fast, the other is not. haha

VE = 190hp/190ft lbs
95 VQ 190hp/205ftlbs.

 

well...I have the MEVI...so that would negate the fact of his variable manifold...but I know for a fact the 95 maxima 5 spd is lighter than the 94 maxima 5 spd by a good 200 lbs or even a little more....but in shear mods that I have, and the two mods he has I would think would decide this battle....by the way, I am talking about racing from like a 3rd gear pull...so shifting is not a factor....cause we don't even go to 4th....

I guess I just need to go to the dyno to see if I am missing any major power....can't go to the track yet cause I know my time would suck b/c I have a slipping clutch...but mod wise, you name, I've got it as listed above....except for cams and headers and flywheel....he only has a straight pipe and CAI and STS....and like I said every fluid and sensor I can think of has been changed....lol....

 

MrEous miss the fact that he is fully modded with MEVI even, and the 94SE doesn't even have a Y-pipe? And no, a 3rd gen certainly does not weigh less than a 4th gen, it's quite the opposite really. A 4th gen SE weighs about 250lbs less than a 94 SE... something is certainly amiss. michaelnyden would be trapping at least 97mph assuming he's making the power he should be, whereas the 94 would probably be lucky to trap 93... something is definately up with michaelnydens car if you ask me.

 

so I guess I should dyno and also compression test my car to see what's up....cause I can't think of anything else that would be causing such a performance loss.....is there anything that won't trip a code besides poor compression that would cause a huge performance loss?

 

yeah nealoc, the 3rd gen doesn't even have a y pipe!!! just straight pipe, CAI, and STS....like I said earlier, I do have about 100lbs of stuff in my trunk, but that would mean I am still 150lbs lighter not to mention how much weight I have shedded from full aftermarket header-back exhaust from WSP...!

would coil packs make a huge difference? but those would trip a misfire code I would think if they were bad....I always use 91 octane.....I have to, I have advanced timing from the TS ecu....I think my injectors are fine....I use BG44K like once a year or so....

 

with my auterra obd scanner....on my pda when I put my foot to the floor, the throttle position says 92% as the max that it hits....don't know if that has to do with anything....I know when I have my friend put his foot to the floor in my car with the car off and the hood up, the butterfly valve in the TB is opening all the way...but I don't know what performance difference if any the TPS would make if it only goes to 92%

 

VE power!!! haha

Since you have the Auterra (how much did you pay? And those on ebay are a good deal?), you should be able to see what your timing is doing/air fuel ratio etc... Just have to compare it to the other guy's data and see. If yout timing is really ragged, your ks might be bag (again) etc.......

 

no...i have no codes at all....I just replaced my knock sensor a month or so ago with a brand new one and torqued it down with a snap on digital torque wrench to factory spec...infact on the lower torque spec of the allowable limit....

 

is there anything else that could rob power? EGR maybe? although that shuts down @ WOT I think so that wouldn't be an issue....anything else that wouldn't set off a code that can seriously degrade performance?

 

maybe the 94 just had a good day...... does this happen often?

 

Maybe it's has good day(s) as the first post said "everytime" as in more than once. The VE 5-sp is about a 6.7-7.1 0-60 and around a 15.0 1/4 miler stock

 

you still do not have VTC's

 

c'mon guys...look at my mods...and what I listed him as having!!! nealoc....even with what people are saying...does this make any sense?

 

maybe you cant drive?

 

we raced in only one gear, 3rd.....so there was no shifting involved....

 

maybe you should just accept the fact that VE 5spds are better than you.

 

even with full bolt-ons except for flywheel, headers, and cams?

I am talking UDP, STS, TS ECU, MEVI, Y pipe, B pipe, Cat, Muffler, no codes, 91 gas, new O2 sensors and new knock sensor, Intake, grounding kit....new spark plugs, new fuel filter, clean TB

I'm just gonna take it to a nissan master tech friend of mine and see what's up....I called him about it already....and he was dumbfounded!

 

Have you ever done a compression test on your engine. That would be procedure number 1 in my book.

 

good idea....I'll have to pick up a gauge after work today....wish me luck!!! if my #'s check out okay.....I will have no clue as to what it could be...

 

Also, what RPM do you have your MEVI switchover at.

 

5000rpm...

 

That's too low. That will make you a little slower but not enough to account for what's going on in this race. Something else is still going on, but change your switchover to 5200 or 5300.

 

i thought 5000 was the optimal switchover...didn't someone dyno and show that 5000 is the perfect changeover after dynoing with several different changeover points...??

 

nealoc..., how much slower would that different changeover make me in the 1/4?

 

5300 was optimal on my car. With my current RPM switch though I can only specify every 200rpm so mine is set at 5400. I have tried 5000 before and I don't recall the exact figures, but I think it was on the order of .1s and 1mph lost. So like I said it wouldn't make the difference in the race you describe, but it will make a little bit of difference.

 

Actually there is only about a 150lbs of difference between the '95 and '94...'94 being heavier, my bad. I wonder what both of your dyno plots look like...also wondering power output of both cars. You may only walk on him but the difference between a couple of tenths in the 1/4 is ~10-20hp.

I could be mistaken...but I don't think anything is too far off to be freaking out.

Also, what are the similiarities of gearing from 3rd to 4th gen Maximas?

 

well, I did have about 150lbs of stuff in my trunk which I know for a fact he didn't, so that would account for the weight difference, however, the 4th gen is more aerodynamic....lower drag coefficient, and the gearing is identical I believe.....with all my mods I should be putting down around 200whp on a dynapack....

 

I don't see why this is so odd. I think if you guys race off the line the VQ should be quicker. Even the VG guys "try" to harass the VE guys about being slow off the line. A couple of years ago here in Atlanta during one of our outings there was a VE 5spd with just an intake , myself and several others with I/Y watched the VE slowly pull away on the highway. (At this time no one was equipped with the VI) I think a few Mags (yeah I know mags times mean nothing) had a 92SE 5sp 0-60 in the 6.7 or 6.8 range. Not too shabby for 12 years ago.

 

You guys don't find it odd that a fully modded (including MEVI) 4th gen, which should be putting around 190hp and 190tq to the wheels, is barely pulling on a 3rd gen which is heavier, and probably putting 165hp and 170tq to the wheels? Wow.

 

maybe the 3rd gen is spraying and doesnt tell you

i agree with the the fact that you wshould be pulling pretty hard on the 3rd gen if its basicly stock

i made 170whp 185wtq and the closes race ive had comparible was an 01 5spd and i was just barly pulling on it

i also raced a 96 auto with i/y and i waxed it hardcore from a 60 roll

 

I know the driver...he's not spraying...I know my tranny is not in the best shape...and my engine has 132K miles on it so a compression test and dyno are in order!

 

when i had my 95 gle i took my brothers 92 se both only had intakes, and both were auto, and it was from a roll

 

I did race this same guy when we were both stock....I pulled on him pretty good!!! almost like with all this modding, I have lost power...LOL
