man these numbers are makin me crazy while im waitin to get my fourth gen. You said these numbers are no a 3.5 swap? What exactly is that? I read that it is supposed to be the new 02 Altima engine?

 

nismo where can i find the headlights in the pic of the burgundy fourth gen.

 

UPDATE: The guy is going to plug the Consult II in the car tomorrow before I go to the track, and I'll bring him the 300zx ecu. He'll do the harness adaptor next week and I hope to have it tuned for next weekend (There's a HUGE event at the track on June 18-19).

I am going back to the track Tomorrow (Saturday). I'm not expecting anything great since it is incredibly hot and humid outside, but I hope to at least do better than last time (14.01@103). For one I went back to zip ties (I put about twice as many though) and will shut off the fan while running.

I ALWAYS forgot to shut off the fan while doing my runs, which may explain why I couldn't get low 104 mph trap speeds like two weeks ago. Got a few low and mid 103's.

I am thinking of removing the 2k2 IM butterfly valve bracket completely and replacing it by a plain metal plate just to seal the IM up. Should kill my low end and gain some top end. Only for the track though. Takes 2 minutes to remove and I driving around with no low end would just suck.

I still don't have slicks, still the all-season yokos

 

Awesome! So what made you think about a z32 ECU? There are several sensors that are different than your car. But if this guy knows he can get it to work, that's great. Why can't you alter your stock ECU?

The only reason I started messing with the ZEMulator with a z32 ECU is b/c it has a EPROM that can easily be emulated by the ZEMulator tuning system. I couldn't use my stock ECU just b/c it has no EPROM. I am still working on getting the ZEMulator to work in the VE Maxima. I have no idea when it might be up and running.

 

He's working on a older Supra this morning, I'll call him in about two hours, I have to remantle my front end anyway.

The z32 ecu is the easiest to work with for him. We're gonna take the signal for the maf and other sensors out of the 95 ecu and use them in the z32 ecu. We're basically "brainwashing" the z32 ecu.

We couldn't use the OBDII ecu for what I want (major ignition timing advance) because it will throw a code and retard the timing when we get past a certain point. The z32 OBDI ecu won't do that, and is muuuuch more flexible than the OBDII 95-96.

 

Yes it is!!! Please continue to update us on this project.

 

They weren't enough cars tonight in the street class so they put us in the Semi-Pro class (14.99 to 9.00, no delay box). Pretty f*cking hard when you're on street tires and got exactly two weeks of experience in drag racing.

My reaction times saved my @ss. I dialed super slow and played with the brakes on each run (street tires are too hard to be consistant). First run I cut a .008 and won against an 11-second malibu. Second round I was up against an all motor civic doing mid 12s@112-113 mph. He cut the worst light ever and had some problems - I won with a .085 R/T and a 15.29@71 mph lol.

Third round I was against a 5.0 mustang trailer queen dialed at 11.59. He actually ran very close to his time (11.63) but I had him on the reaction time (.063) and won by a very thin margin slamming on the brakes (.033 win margin).

I was back in the lanes for the semi-finals but it got cancelled due to the weather and we split the 500 bucks.

 

Way to go! Sounds like a good night! Whenever I win in my class in Vegas, I was lucky to get $100.

 

Good stuff, it seems that Aaron and I are the only bracket racers and good to see someone else get interested. There is a lot more to bracket racing than meets the eye.

When you see the pro's cut unbelievable lights and times within .002-004 every round it shows how much work it takes.

One guy I was parked beside in the pits last race was running a 10 sec chevy II and he did a .002 light and the guy beside him ran a .001 and won. Of course that was with a delay box but still crazy times.

Are you racing at Sanair?

 

Napierville for now, I hear it is slightly faster (even though Sanair is better built overall). The track got a makeover in 2002.

I like bracket racing (my dad raced for about a decade), but racing without slicks is a major pain in the @ss. My 60 foot could be a 2.1, or a 2.5, so I just dialed a mid 14 and drove like it like I had a 2 by 4 behind the gas pedal. I am trying to get a set of 22's for next weekend, so I should be able to run consistant mid 13s.

It was so hot, my first three runs I trapped at 99 mph, 4-5 mph slower than it should be. The best I managed was a 14.16@102 with a 2.16 60' when it got cooler. Other mph were 100 and 101 mostly. I hate being slow.

BTW, how much would going from 25-inch street tires to 22-inch slicks hurt my trap speeds? I don't floor it completely in first even when I get 103-104 mph.

 

Aaron can probably tell you better than me, I have only ran streets a couple of times last year.

Normally I don't pay much attention to trap speeds either, they are an indicator but the et is king.

 

I have never paid attention to my trap speeds. If I tell people I have a trap speed of 94mph, they will think I can only do 15 flat in the 1/4. Far from the truth. ET is the ONLY thing I pay attention to when bracket racing.

I did a quick CarTest for a near stock VQ 5spd and the traps didn't change at all by switching from a 25" OD tire to a 22" tire. If you are already shifting into 4th gear before the end of the 1/4 mile, then I don't see how 22" slicks will hurt your times. CarTest shows 22" tires are a half tenth faster and the trap is about the same. But, the drop in 60 foot will help your overall times. A rule of thumb is, for every tenth you can shave in the 60 foot due to a gain in traction, you shave 2 tenths in the 1/4 mile ET.

When I bracket race, my 60 foot times never vary by more than 2 hundredths. And my ETs usually only vary up to 5 hundreds from my dial in. But, there are a lot of guys in my Pro class that hit their numbers or are within a hundredth on a regular basis.

But I wouldn't be worried about your trap speeds. I would just get those 60 foots more consistant by getting those slicks. Even if you went with 22" MT, it shouldn't hurt your time at all since you are already shifting into 4th gear.

Also, maybe my CarTest gearing is off, but it shows that you can stretch 3rd to 107mph at 6600 rpm. Does that sound right? Everything I've ever heard of a 4th gen VQ 5spd, they are almost topping out 3rd gear at only 95mph when they are close to stock.

 

I tried to ride out third but it hits the rev limiter at 94-95 mph in 3rd gear. I ALWAYS have to shift into 4th.

Is it possible to check with Cartest what my 13.68 run would have been with 22" slicks instead? The 60 foot was a 2.13, say we assume a 1.88-1.93, that would mean 13.18-13.28 with the same 104 mph trap, right?

 

Can you get on AIM right now? I'm "adogg18". I have most other instant messengers also.

 

Aim doesn't work for me. Long story not worth telling. We can talk through PM, though.

 

Oh ok. Well, I did a quick cartest with a 1.9x 60' foot and you'd be around 13.2 with the same trap speed. My only concern is you having to shift into 5th gear with the 22" slicks, which should never be an option! My Cartest gearing is off, so I have to double check my numbers. Without the correct gearing, I can't tell for sure if the 22" slicks will hurt you or help you. I am guessing that they will help your ET and trap speed if you are able to stay in 4th gear.

Try not to PM me, especially during the work week since it's frowned upon to browse the org while at work. Send me an email anytime though! I don't have cartest at work though.

 

stocvk gearing and tires VQ 5 speed is 98 mph in 3rd @ 6500 rpm.

Thats why i love my ecu i will never have to shift to 4th gear in the 1/4 and actually never have been in 4th in the 1/4 ever. I would have to trap over 110 mph to have to shift into 4th

 

I pass the traps in 4th gear at 5000-5300 rpms at 103-104 mph on 25" street tires (with only 20 psi in them). So logic tells me that even with 22" slicks I would be nowhere close to 6550 in 4th. I would probably pass the traps at around 6 grand.

I doubt the 4th gear shift hurts me very much, given that I got nearly 105 with the stock 2k2 manifold, stock redline, no tuning, and a relatively heavy car (compared to you guys).

 

If I have time once I get home, I will do a quick CarTest and see if I can get your gearing right. For some reason, it's off. But if you were to rev 6K through the traps, that would be pretty nice!

 

Even if my math is off, I HIGHLY doubt I would pass the traps at higher than 6550.

 

6800 ish is about where you'd be in 3rd ... Be nice to see what you would do w/ extended limiter ...

What about 4th gear with the 22"?

 

yeah that 2k2 powerband is toatally diff than mine . My car doesnt come alive till 5000rpm and peak power is prob 6700-7000 rpm for my car. when i cross the line i will prob be in the 7k range.

 

Mine comes alive around 3500-3700 (since my 2k2 VIAS doesn't work) and pulls really strong till redline. Even shifting at 6500 I don't feel a drop off like 2k2+ owners seem to complain about.

 

Even with the VIAS is wouldn't come alive until about then as well ...

 

I just ordered two brand new M&H 23.0x8.5x15 Slicks

I should get them Friday. Will mount them on two sawblades to keep the car stock-looking

I am considering going back Friday night to practice a little (first time on slicks) for the event on Saturday.

They're expecting 700 cars and 10,000 people on site (judging by the 2003 and 2004 editions, that's not much of a stretch). 9 AM till dark.

The fastest class (all turbo 4 bangers) are expecting someone to break 9s. The all motor class is a bit too fast for me (low 13/high 12, sometimes mid 12s), so I will probably only do bracket racing.
