This past weekend I hit the dragstrip for an Import-Allstars-Meet. I have raced this particular track several times last season, and have always been .2x slower and my mile per hour about 2-3 mph lower. The elevation above sea level is the main reason e.t.'s and mph differ from the other tracks here.

Even though I beat my pb of 13.8, I will have to wait until March at my local track to see what I can squeeze out of the new setup. I can already predict it will be a 13.5, maybe a 13.4 from the times I got over the weekend.

00VI/Greddy EU vs. USIM/Technosquare ECU
Test Track: Lakeside in Taupo

New Setup: 13.734@99.56 Mph (00VI/EU)
Old Setup: 14.097@96.00mph (USIM/TS ECU)

At this track the 00VI/EU lowered my e.t. by .363 and bumped up my mph approx. 3.5 mph

I ran the car WOT about 4 runs before we started running the event which was a fixed index bracket. I selected to 13.90 bracket, with the sport being not to break out, which was quite tricky.

Timeslips

3 Best of the Day
13.734@99.56 - 60 ft 2.001
13.766@98.68 - 60 ft 2.064
13.882@98.25 - 60 ft 2.094

In fixed index both turbo and non turbo cars were racing together. I rarely race anything but all motor here in NZ. So starting the competition was kinda creepy looking at Rx7, WRX STI, an older EVO, rotary powered cars (ex. Mazda RX2), several Subaru Legacys (this is an AWD turbo car), nissan silvia, etc. hard to remember them all.

Results
97 Nissan Maxima takes 1st and $300 dollars. By far the most money I have won racing. And still dont know how I got out of all those dog fights on top. I believe what was key was reaction time against all the AWD cars. While most all the cars but a few could run faster than 13.9, I believe most had the same game plan, and with the AWD cars I think they were relying on 60 foots to get them ahead and stay ahead, so thats were the reaction played an important role.

I did gain experience in a different style drag race, and the tricky part was not breaking out at the end but getting there first. I found myself in several interesting scenerios that took some quick thinking on what I should do. Overall luck was on myside, as it would seem every guess or move I made turned out to be the right one. I won one race by .004, a bit to close for comfort aye? The maxima 9-0 on the day. Must have made a great show for all the people watching, lol !

I also love that a Nissan Maxima made it through the field as a huge underdog and came out on top, that in itself is priceless.

As always thanks to the crew here who helped me through the 00VI swap, and of course dandymax for working his magic with the EU. During the off season will go in for some dyno tuning !

I'm glad things worked out. I'm sure the ride feels like a totally new car. Excellent runs!

 

Great job . thats a tenth faster than my best with the 3.0.

Try getting some slicks and getting to the lower ELE track and you may be able to get close to 12's.

What is the ELE at this track and the other one?

 

kris the track i raced on this weekend is aprrox 1300 feet above sea level, where as my local track is maybe 300 feet above sea level. the other drag strip I dont go to much at all is around 16 feet above sea level, its about an 8 hour drive from here, which is one reason I dont get up that way much.

Using the NHRA elevation correction factor for this altieude above sea level for lakeside are as follows

13.734 * .9861 = 13.543

i believe this to be true as I have seen it in real life and it is dead on with the differences in time when i run at masterton, its the weirdest thing, but you can actually feel the car dragging along slower because its much higher.

with my same setup, i should easily hit 13.5 and for the very first time ever break into triple digits. in all honesty i would have never thought i could have beaten 13.8 on this track, but pulled it off. you know if we were just racing heads up i might have gotten a 13.6, was having a wee bit of trouble getting a 1.9 60 foot out there.

the oovi is so cool though, you literally run through the whole power band never struggling at any point, it just pulls all the way through the power band. even broke my 1/8th mile et and mph at this track.

if i can just get the chariot to hold on for one more race, my radiator is just about on the blink, with some leaks.

i think the key stat is the time difference on the same track, and same weather. back when i ran a 14.09 that was with a 1.9 60 foot and the new setup was able to best that with a slightly higher 2.00 60 ft.

the oovi was a wild project and i made it through it, but boy does it totally change the car overall. only a few weeks back i was experimenting with it with no activation for vias and on the good track and could only put up 14.1@96 mph

so the eu and the oovi are a killer combo ! thanks to you as well kris for the fuel rail fittings !!

 

your welcome.

i would say ceasar if your radiator is pooping out then that will affect your times. because if i dont let my car cool with ice for about a hour or so i run 2 tenths slower.

when you go to the good track let your car cool for over 1 hour and you will be suprised on how much more power you have.

take that 300 and get a decent radiator.

 

i hope i can buy one for that here, will start making some calls, im tried as hail having to keep cleaning up antifreeze and water outta my engine bay.

the stock nissan one is fine right ? NZ prices scare the crap out of me, i was under the impression our radiators are not that expensive, might need to get a quote from daveb the parts guy and then compare over here. i would like to just put a new one in as mine is what 9 years old

 

Outstanding job! Now, how about some nitrous for the Chariot ????

 

Wonder how much of that improvement was 00VI alone? I know I picked up .3 in the 1/4 going from USIM to VI on stock ECU. Not knocking the EU but curious as to what you would have run with the VI & TS ECU.
Good times regardless. Those runs are on street tires correct?
Can't wait to get my EU up & running

 

im running hoosier drag radials 225/50/16, very good buy at 180 bucks a tire i think you guys can get in the states on them. i had a very difficult time finding something better than a street tire for a 16 inch rim. they have gotten me several 1.9x and 2.0 is what I saw most of the day at the event.

again, this track is very tough, maybe nascars darlington (isnt that one the track thats to tough to tame?) lol !

as for as the EU, its got a rough street tune, and dan was not able to mess with the (air/fuel) i think it was so maybe still running rich, without a wideband I suppose it would have been risky to mess with that.

but considering the setup i have the max has got some grunt for sure now.

 

Nice dude! You got me 6 hundredths!!! I will be shortly behind you! I have more stuff planned! Hopefully, everything will be ready within the next month or so.

But congrats on the win!!!

 

When you go ahead and get it dialed in with the right A/F ratio your going to be very close to that 13.0 or even the 12's.

As far as widebands...I recently got the PLX R-300. The software is excellent when adjusting your A/F.

 

Great times man, you sure picked up some good power even without a clear A/F tune.

 

ha ! hey dude ! so our saga continues. i rang my wife from the track on the first 13.7 and asked her to look if i snuck ahead of you, lol ! then gave it one more shot and knocked it down to 13.73, just enough to squeak ahead of that beastly 3rd gen of yours ! thats another fun aspect of the maxima crew and the timeslips database. i suspect you are up to something and look forward to hearing about your next trip out. all in good fun of course !

 

what rpm is the intake opening at and I am guess it's rpm activated and not vacuum

 

Vacuum doesnt activate the VIAS, its activated by a preset RPM switch (EU in this case)

 

its set at 5000 rpms

 

Good to see everything worked out for you in the end, Ceasar. Hope to see you dip into the 12's with the help of some tuning and the EU's magic!

 

Nice work CC good to see you Beats the EVO4 and WRX!!
i told this guy it was N/A and he fought i was ball ****ting him lol!

BTW next time you should let me do a run in your car

 

Yeah. That is funny! You had to see if you squeaked ahead of me.

Lately, I've been working on dyno'ing my car on the street. I have it working flawlessly!! I am now able to make as many dyno runs as possible and it's every bit as accurate as a chasis dyno. In fact, it's more accurate b/c your car is actually accelerating on the street in the real world. So I will be making dyno runs for the best ram air intake piping setup for the track, optimal variable intake release point, best heat range spark plugs, best base timing with race fuel, best intake midpipe, and best way to lock up the torque converter while running through the gears.

I have already made about 50 dyno runs so far of various things that I've been working on. It's called Home Dyno. It took a lot of work getting the cable made and tapped in correctly on my car. It's not easy to get it to work with our coil-on-plug design. But now that I've figured it out, it's not too bad to made an inductive pickup cable for your laptop.

 

Aaron... you got a link for that Home Dyno by any chance?

Chris... I did tune your A/F a bit based on what I know about the setup you have, so you shouldn't be too far off but you might still be able to pick up a couple hp on the dyno. And BTW, I never got to the dyno either to fully tune my car last year but the street tune isn't all that "rough" I think...

 

sweet ! im not going to make you eat your shorts just yet, masterton will be the testing grounds. ha ! you dont have anything to worry about though, its heaps faster down there, versus up on the hill !

 

Yeah, http://www.charm.net/~mchaney/homedyno/dynokit.htm

You can make your own cable like I did, which is NOT as easy as it looks. Or you can just get Road Dyno and make your life a lot easier.

I had a lot of problems to overcome with my cables. It wasn't as easy as just following the directions. I spent months perfecting it on the VE. The VQ will be similar I'm sure b/c of the coil-on-plug design makes it a pain to get a good signal.
