1/4 Mile Run Times - 1994 2.3 / Automatic

[The Bandit]

Finnaly ran my miserable little truck tonight.

1994 2.3/Auto Regular Cab, Stepside. Splash. 125,000 granny miles.
225/70/R15s. 3.73 Open Differential. (Thought it was a 3.23)

2 1/4" exhaust from header with cat delete and 2005 Trailblazer resonator dumped at rear wheel. All slack eliminated from throttle cable. Air intake relocated from coresupport to outside wheel well, beside frame. Intake baffle removed, tubing painted reflective silver to prevent heat soak. Hood weatherstrip removed to aid in ventilation. New timing belt, new paper air filter.

My truck needs to be aligned badly, has 20 pounds of bondo in the hood, fullsize spare, hedgetrimmer, drill, extension cord, and some other assorted tools in the truck chest.

I made all these runs off idle with the truck in (D) for the sake of consistency.

Run #1

20.659 @ 66.864 mph.

Drove the truck 40 miles down there and ran it just like it was.

Run #2

20.682 @ 66.965 mph

About 5 minutes after the first run.

Turned the truck off and put the intake silencer back in, helped my friend with his destroyed ball joint and let the truck cool down for about 30 minutes.

Run #3

20.124 @ 68.134 mph

Five tenths of a second and 1mph improvement. I'm still undecided if this was from the silencer (which actually made it feel more bogged down past 45-50mph) or letting the thing cool off.

Run #4

20.251 @ 67.301 mph

Right after the above run

Run #5

22.462 @ 64.513

Sat and idled through the lanes after it got crowded, and all the motorcycle guys had their runs for about half an hour. Ran the A/C most of the time. Bogged out at about 20mph and struggled to recover.

----

I never took the intake silencer out and let the truck cool down. I think with smaller tires (too much unsprung weight) a electric fan (I think the static fan bogs it down high in the RPM's), and 180* thermostat (this truck may hit high 19's at most. i did think that the gear ratio was too high, but I looked at the tag more closely and its a 3.73 out back. Not a 4.11, but not too high either.

I made this post mostly because I have searched for it many times to get an idea of what my truck would run in the 1/4 mile. When I did it was just a post or two of speculation or someone who had ran theirs with a stop watch and a section of road marked off. I know these times are not fast, but they are accurate.

If I make any more modifications or passes, I will post them as well.

try a lower rear end gear,got a 90 ranger2.3,5sp,3.73 open diff,ran it through the 1/4 mile 4 months ago and got---18.68/73.129mph,bone stock.

 

[The Bandit]

Haha, that is a hell of a improvement over my time.

Anyone else feel welcome to post their 1/4 mile times as well. I've got a 3.73 Explorer rear end at the moment, but its going in my '54 F-100 in the next couple of months.

I may go ahead and pull the intake manifold off when I put 8 new plugs in the motor and port it. From what I understand, they weren't port matched to the head very well. It probably has some carbon build-up in there too.

i beat a g5 today in a quarter mile haha. A standars tranny would help you also. take the hood off and get more cool air to it. lighten that thing up. my 3rd gear is my bread winne most cars cant get up to the speeds that these rangers run in third gear wit the 3.45 rear end i have. i made up bout 5 car lengths wit 3rd. get rid off that ac crap too that has a lot of drag that will rob you of power. i am as unrestricted as i can get with out getn crazy wit emmissions and all that. These things dont hook up well of the line so posi is the way to go also. that intake idea probly wont be worth the hassle for what you are going for.

 

[flaminranger]

you need to look at the 60ft times as well to see where your power difference was made.
whether at 2000 rpm or 5000rpm that can help you figure out when in the powerband a change made a difference

 

[steve63]

well i must admit i kinda cheated when i did my run,i popped out the air filter cartridge,lowered the tire pressure in the rear to 15 pounds and did a burn out (uh somewhat of a burnout),port matching the head,intake,exaust would help,and also running an electric fan to take some drag off the engine,that might get you another 5-8 horsepower on the 2.3.

my parent's 98' Infiniti Q45 can do 4seconds flat (stock) on a 0-60.

Large v8 lol

My best was 10.15 at 145mph with a 1277cc Suzuki 4 cyl. Of course it's on a bike so that may help.


Seriously though, run brackets. Consistency is where it's at. That takes all of the vehicle out of it and makes the contest about the driver. I won a bracket racing night once in a 300M loaner from the Chrysler/Jeep dealership my Cherokee was being serviced at.

 

[The Bandit]

Just saw a 2.3 turbo manifold and complete turbo set-up on ebay for under $100.

If I only had the time to do the swap I'd be whistling my way to a high 18, haha.

Using my super secret program you are running about how you should be. The mph is the telling thing, and the gear ratio doesn't matter much for that.

98hp is stock. If you couldn't get it to shift at redline with the auto then that would cost you some power and top end speed. My program puts your curb weight at 3300#, which is too heavy. It should be around 3,000 and you should be running 71mph.

I think it's not making 98hp. You are down 10 and it might be the shift rpm, or some of the stuff you illegally removed is wrecking the fueling from the computer.

Not a chance. Hell, dropping it out of a plane it wouldn't do it that fast.

[The Bandit]

Neat program. By putting in 85hp and 3300 curb weight, it brings up the correct 0-60 time and runs a 20.4 in the 1/4 mile. Probably close to what it would run.

The factory cat was clogged, and the OEM exhaust only had a pre-converter o2 sensor on the header collector. The stock stamped steel muffler was full of rust and other garbage. I fully intend to put a converter back on it as well (No smog laws here, but there is no need in polluting the air) and probably switch mufflers again. I'm starting to suspect the Trailblazer resonator may have some kind've restrictive suprise inside.

Ummmmm, no. that would beat a lamborghini diablo awd 6.0L.

 

[Ranger Kip]

they dont have the 98 Q45 on that list

Anyways, yeah, looks like your times are not too bad, needs some work though, as is, it beats my truck after you start use the brakes!

There you go. You are still WAY off. Of course, you think a 4.1 liter is a LARGE v-8 so....

Another benefit of the newer engine is that it is lighter, which takes some load off the front wheels. This gives the big sedan a more nimble feel and improves its handling on twisty roads. Although peak torque is at a relatively high 4000 rpm, there is usable torque low in the power range and that means better low-speed acceleration. There's lots of power here and Infiniti says the Q45 accelerates from 0-60 mph in about 7.8 seconds.
