Went to track again: PB 15.995

[GrandPrix34]

Still don't know why in the heck I'm in the 16's...here my time slips:

Run#1
Reaction: .363
I1: 2.375
I2: 6.790
I3: 10.395
MPH (I3): 68.489

E.T.: 16.051
MPH: 87.756

Run #2

Reaction: .498
I1: 2.350
I2: 6.753
I3: 10.356
MPH (I3): 68.514

E.T.: 15.995

MPH: 87.979

The rest of the runs were consistent 16.1's with a 60 footer of 2.4XX and a PB MPH of 87.979MPH and a PB Reaction time of -.0289 (ALMOST PERFECT!!!)

So what do you guys think? Am i still not launching right or is my car just a slow 16second piece of shit? Lol

ONe thing that is wrong with the car but I doubt has any bearing on the runs is that my 2 rear struts are shot. The one on the driver side rattles over bumps and on the road itself. After we left the track I thought my mufflers hit the bottom of the street on a dip i took too fast, but my friends in the backseat said it was the struts bottoming out.

I can literally put my hand on the trunk of the car and make the car shake by pressing down repeadetly and it makes the car stay bouncing for about 1 sec.

Can bad shocks have anything to do with my 16's!?!? Please say yes!

Based on the time of the year (temperature), I say your 3.4 is within the average. I mean hell, Motor trand tested a '95 Monte Z34 and ran a 16.8.

[Canada]

Your 60' times aren't THAT bad considering its a 3.4 DOHC automatic.....

What exactly are your simply bolt-ons?

How are you launching? What shift points are you using?

[GrandPrix34]

one thing i want to mention is that by the end of the track (passing the time towers) my car's rear starts bouncing like it wants to loose control...

Mods are FFP Pulley, chip, dogbone, warm-air intake, no cat, 2 flowmasters, 2 glasspacks, and thats it...wow, my mods suck!

Oh yeah, and gasket matched lower and upper intake. (Mild porting, runners not cleaned up, just gasketmatched ports)

[acar]

those are some not bad times but i have a car with a 3400 but i bet it would beat that time not trying to be cocky or nothing but i have raced cars with 3400 dohc and smoke them.

[GrandPrix34]

In my defense, qouting Vegeta (Ben)...


Public schools have failed you
:D

Don't take it personal, just busting your chops newbie. I have raced lots and lots of cars with the 3400. heck at the track I raced a modded 3400 and the only thing he had on me was torque at the beginning...still not enough.

But if you feel you got a good 3400 on your hands, badass! Take it to the track and let us know how you do.

By the way, its 3.4L DOHC not 3400 DOHC.

[acar]

what all u have done to ur car tho?

[Aaron]

those are some not bad times but i have a car with a 3400 but i bet it would beat that time not trying to be cocky or nothing but i have raced cars with 3400 dohc and smoke them.

Why don't you tell me what cars you have raced with a 3400 dohc?

[acar]

its a 3.4 dohc i fucked up on the typing i was thing about my car witch is just a 3400 i have raced the monte carlo z34

[Aaron]

And that MCZ34 could have amde it a very different race had it not been a 96-97.

[RacerX]

Based on the time of the year (temperature), I say your 3.4 is within the average. I mean hell, Motor trand tested a '95 Monte Z34 and ran a 16.8.

You sure that's not for an LS with the 3100? I've only ever seen 15.5 and 15.8 from Motor Trend for the 95 MC Z34, and 15.5 for the 96 MC Z34. Road & Track and Car & Driver tested them around 16.1. I've never seen a magazine tested time slower than low 16's for a 3.4 DOHC W-body.

[RacerX]

And that MCZ34 could have amde it a very different race had it not been a 96-97.


Do explain this gibberish, Sherlock.

[RacerX]

As for the rear struts, you're probably losing some initial torque in the suspension as a result of it, and possibly traction.

[GrandPrix34]

c'mon guys lets not get my Track Posts locked like my last one

And yes, the MC had the 3400 I seen the hood popped open and spoke to the guy. The damn headlight comes off easy too!! :evil:

[BIGBULS]

Your trap speed is still a touch slow for those mods, but it's ALSO a little high for a 16.0 if you understand what I'm saying.........

Lets start with the first thing:

How EXACTLY did you launch?

Then:

What was you EXACT shift strategy?

After we get this out of the way, we can THEN start looking into whether something may or may not be messed up with your car.



ONe other thing..........as close as you can tell, what is your track's elevation, what was the wind like, temp and humidity. If you don't have a clue, don't guess..........just tell us what track it was (a lot of the time you can find out elevation and stuff online...or by looking for nearby towns).

[BIGBULS]

And acar..........bear in mind that these cars you are talking about have to haul around an extra 350-400lbs than you do (your Alero is right around 3100-3150lbs vs a 3.4L DOHC W-Body at ~3500lbs)..........yet they are STILL fast enough to pretty much match you dead up.

The ONLY advantage I'd give your Alero is right out of the hole (the LQ1's launch is hampered by a complete lack of low rev torque), and maybe a slight one off the 1-2 shift (the LQ1 get screwed over by the short shifting 4T60-E.....and there is supposedly NO way to manually hold off the shift to a higher rpm)..........even then, in a full 1/4 mile I could only see you sitting around 1 car length (about a tenth) ahead of one.........plus, I bet it's be just starting to pull on you.

And from a roll...........I have every confidence that any of these LQ1 powered cars would start to walk away (not to mention they don't have a silly 106mph governor :D ).

[sonyman87]

its not your launching, your mph is .5mph to low. could be wind or just the track, or just the fact that you have a high milage vehicle.

how many miles do you have?
what motor oil and weight?
type of tires?
mods?

[Aaron]

And that MCZ34 could have amde it a very different race had it not been a 96-97.


Do explain this gibberish, Sherlock.

Well if the MCZ34 he raced was a 98 or 99, it would have been a lot easier to beat from a roll on start. Or if it was a 96-97, then he probly just ebat it to 40 or whatever.

[EurosportZ34]

Most definately...that time does seem quite slow for your car. Auto 3.4's have a 1/4 mile time of 15.8, and with your simple bolt-ons I think that it should be way below that time...maybe 15.5 depending one what you got done.

Milewise, I have 92240 on the clock.
Motor oil is DuraBlend 10w30 (about to change to MaxLife 10w30 *highmilage oil*)
Tires are FUTURA 755's (ugly ass tires, cheap though)
Mods are Pulley, chip, dogbone, flowmasters (x2), no cat, 2 glasspacks, warm-air intake, and thats it...wow my mods suxs...

I have a set of heads I'm working on but even if I dont do that great of a job at porting them, the new valve angle job and head decking should do some good in increasing compression some.

[BIGBULS]

Ok..........so I appear to be getting ignored here......... :wink:

How did you launch, and what was your exact shift strategy?

You can get your mph up by holding 2nd to just shy of the rev limiter (manually), and your 60ft times are still pretty slow..........so that's why I'm asking about the launch.

It seems to me that your car still has more in it, but may be being held back by technique (or lack thereof).

[GrandPrix34]

when i pull up to the staging lanes, i pass the waterbox and do 1 quick burnout out of the water to dry the tires...then i stage tripping both lights...then i brake torque to about 1800K and when the last yellow lights up i hit the hammer...the RPMS slowly climbs from 3-3.5K.

When staged i bring the shifter to 2nd then let the car shift out of 1st and let the car pass the final light in second almost redlining (chip removes RPM limiter). You think I should shift into 3rd?

Just wanna let you know there is no way around the waterbox! So i have to go through it

[Aaron]

I recently ran an auto 3.4 dohc at the track in Pueblo, Co where I ran my 16.85 so long ago. ANyways, the car would not burnout from a standstill, it'd barely chirp. SO I htought, it helps my car to spin the tires a bit, let's see if it does this. So I drove through the pit by choice, and didn't do a burnout. I went right to staging. It spun them for about 10-15ft, and my times dropped by over 2 tenths consistently.

SO try this if your car will not burnout regularly, drive throughthe pit to get them wet so they will spin.

The best launch in my car is to put it to 4k and drop it. They spin for a bit, but when they hook up, the think just bolts. And with a FWD, even if they are spinnign they are still pulling you forward.

[acar]

the monte i raced was a 96 around i belive and i raced it from a roll and yes that is right i do have alot less weight then those. that is why i do pretty good and my friend sl3196 has a gtp and as u guys can read on the race forum i kept up with it but how could that be a 3400 keep up with a 38sc hummm weight and how they drive the car i think anyways but the gtp will smoke me pretty bad off a dead stop i will keep up with it off a go tho.

[sl3196]

Lets try it from a 30 roll travis instead of a 40! :D

PUNCTUATION!!

You are doing the right thing holding 2nd gear............even though the power levels off around 5500 and starts to taper away past 6000rpm, you are still making more power up at 6500+ rpm than you are in the next gear (where you'll drop to not far over 4000rpm). So that explains the nice high trap speed..........

But as Aaron pointed out, it's much better if you can get wheelspin...........perhaps try brake torqueing the car to a slightly higher rpm (full stall is aroun 2K rpm IIRC).........just do whatever you can to GET wheelspin...for you, it is GOOD. Remember.......street tires grip best when just barely turning over, and since your powerband doesn't really start until ~3500rpm......... :D

The only other thing I can think of is to play with the gear selector a little to try and hold 1st gear to a higher rpm..........I was always told that LQ1 auto's shift 1-2 (under WOT) at ~6200rpm regardless of what position you put the selector in, but maybe your's will shift a touch higher in one than another........it's worth a try.

Your Alero isn't slow, but having taken a Grand Am SE (stock) to the track (it's IDENTICAL to your Alero mechanically and weight-wise), I can tell you that a GTP will eat you for lunch if driven by a competant driver. I've also messed with 3 seperate Grand Am GT's (an '00 [Intake/Shiftkit/Exhaust], an '01 [stock] and an '02 [Intake/Exhaust]) which have better gearing than your Alero (3.29 vs your 3.05), and in 2 cases, more mods............and NONE of them are as fast as another friend's GTP (which has a K&N drop-in)...........and said GTP owner is ALSO the owner of the stock GAGT I just mentioned.....

As for comparing your lightwieght 3400 to a heavyweight W Body 3.4L DOHC...........I'm sure you'd be able to win any stoplight to stoplight stuff (<50mph), but from a roll, or any race that goes to higher speeds, an LQ1 WILL get by you..........




BTW...........if you doubt me, I have some interesting video for you...........

[god910]

I doubt you, but just because I LOOOOOVE ME some video's. 8)

[sl3196]

So now I am not a competant driver bigbuls? Every car has its slow points and my GTP's is at 40. If we kept going no doubt I would pass him.

[BIGBULS]

Well..........did you manually select 2nd gear? That helps right there (no kickdown time).

Also, how far WAS your race? Something like 40-55mph is over so fast that it doesn't give you much time to pull at all (unless your car is just some monster). Add in the fact that he may have just outreacted you, and you see the problem.

Try going from 0-105mph (right before the Alero's governor calls it quits)...........if you can keep a lid on wheelspin (you want the tires squeeling but not actually spinning up to around 20mph...which is where you can finally be at WOT), you should put buslengths on the Alero..............I'd guess an easy 10 car lengths.

Just be sure you start with the gear slector in "2" and hold of the shift to "3" until *just* shy of 6000rpm for best results...........be aware that YOU have a governor at 108-110mph in "3"...........you have to go up to "D" for the car to keep pulling 3rd (and eventually shift to 4th) and hit the 2nd governor at 126-128mph.

Damn server is now being gay...........

I'll post them tommorow if Eric (the server owner) has it unfucked.

[acar]

i know the gtp would kick my ass dont know how much but i know for a fact the grand am gt wouldn't beat me raced a few there good races but i win. the gtp would kick my ass from the stop dont no about the 10 car lenths tho dude thats is alot i would be saying 4 or 5 but not 10.

THEY ATE ME ! A FUCKING SHARK ATE ME!!

[BIGBULS]

The discussion has been carried to the other thread.



I still think there may be another issue with GrandPrix34's car...........It SHOULD be capable of running 15.5-15.7 with no real problems.

*I* think the launch has a LOT to do with it, but there may be a tranny issue (?) or something else.............not sure.

Still, get those 60ft's down into the 2.2's before you give up........you HAVE a decent trap speed........now you just need to get the car moving quick.






Maybe your cam timing is a little off?

[GrandPrix34]

I posted a vid of a 1/4 run...its in the 5 speed 3.4 Vid thread in the general section.

If you see, I stall at 2K then floor it...it stalls about 1 sec from 2 to 3K then gains momentum...what can I do and at what RPM can i stall at to obtain a better run in the 60 footer? MPH is still around 87-88 as a trap speed so I know the car has potential for more like you all mentioned

[BIGBULS]

I would play with different stall speeds...........

Try stalling the car from right off idel all the way to full stall in 50-100rpm incremenets.............then see which gets you the most wheelspin.

Just ensure that you use the same pavement type for each launch, and give your tranny time to cool down between each attempt (in other words...drive for a bit :D).

My bet is 1800-200rpm will be it though..........
