I recently had my car in for some warranty work so reverted back to stock. After getting it back I went to the track last weekend and with slicks the best I could muster was a 14.6 @ 92 mph. I also tried the car stock with street tires and ran a 14.7 vs a 15.0 using a 2k4 rental with a 5 spd auto the previous weekend.

So this week I put the exhaust back on (HS headers & B-Pipe) as well as my intake. Today I ran a 13.6 @ 103 with absolutely no other changes and similar temps and humidity.

This week I will put my Tokico's back on with some new springs and try a couple of other minor mods before going back to the track next saturday.

After next weekend I am sending in my ECU to get the TS limited spec flash mainly to raise the RPM so I don't have to shift into 4th with my auto running spray. Presently I am nitrousless and am planning on finishing up the season N/A.

I did run a 13.5 earlier in the year and think that a 13.4 is achievable when I get my other mods completed.

BTW I am getting good at installing the headers, took me 6 hrs all alone, which is pretty good for a Grandpa working outside with no hoist.

 

Are those in Canadian seconds?

Just kidding.

Beautiful times. Hopefully it will show people the importance of a complete setup (intake and exhaust). What rear section are you using. Also if I may ask the the NX Maximizer allow you to moniter A/F real time?

 

Auto right?

 

1 second???

i havent been around maximas that long

but is this for real?

 

Damn Jim......lots of work for you. Good thing to know you're a leader not a follower. Good info.

 

Very much so. Good info.

 

Even though the maxima VQ35 is extremely powerful out of the factory, there is alot of untapped power available with just minor modifications like intake and exhaust, (and especially y pipe)

 

The Maximizer does not monitor A/F unless you have the FJO wideband which will connect to it. I currently have the Tech Edge wideband which does not work with the Maximizer, however I am going to sell it and get the FJO unit which is very expensive in comparison but it also comes with a new data analysis program which looks great. It will log in both armed and disarmed mode and will plot A/F, RPM, TPS, Nitrous %, Gear, Acceleration and time.

I have also tried different a/f's N/A ie 12.5, 13.0 and 13.5 with no appreciable difference in 1/4 times.

Oh ya the rear section is from Budget. 2.5" T-304 Mandrel bent. They installed it for me with a straight pipe and gave me both resonated and non resonated flanged sections. (I didn't run the non resonated section for very long, an old guy like me can't stand high noise levels.)

I mainly wanted to show folks what they can expect from limited mods, what I did cost approx $750 and can be duplicated by anyone. As you can see from my stock times this car is no factory freak.

PS In OCT there will be an feature in HCI Magazine on my Maximizer install. I was asked to take a bunch of pics and do a writeup which will hopefully net me a few brownie points with NX.

 

very impressed with the little comparison. Nice to know that if I added headers, it would basically be a sure entry to the 13's on street tires.

 

That's a little misleading IMO. 2K2 Autos have trapped and post quicker times stock. Your 92 mph trap speed is really low. It could have been conditions, bad gas, etc. I/E/H aren't going to add enough power to increase trap speed by 11 mph.

 

The low trap speed is due to the slicks, it traps higher with street tires.

 

Maybe the timing equipment malfunctioned. It does happen.

I saw a 6G Accord V6 w/ no mods post a mid-14 second ET w/upper 90mph traps on the board. But, we all know that's pretty much impossible!! (unless Honda mistakenly put a J32A2 motor in it).

 

Thats really not a fair comparison. I have watched Neal run slicks vs streets in his 4th gen and the mph is fairly consistent. The ET was different, but mph was within a couple of tenths. To gain 11 mph in the traps, you are going to need a lot of power. I/H/E doesn't add nearly enough to do that.

 

Neal doesn't run 22" slicks either, I usually trap 3 or 4 mph higher on streets which I rarely ever use at the track. Regardless the weather was comparable and those were the only changes made. I run 94 Sunoco always from the same station.

I guess there must be some magic in the air somewhere. I made 9 runs stock a week ago and 10 yesterday and all times each day were with .2 secs.

Also the 2k4 I tried out on the 15 Aug ran consistent 90-91 MPH traps over 13 passes I made so I don't see why you think the trap is low.

 

I'm still laughing that you took your rental to the track.

 

It is low for that 14.6 that you ran, most that run 14.6 trap high 93's to one guy that trapped 95 stock. Most that have trapped at 92 usually run 14.7's-9's. That rental you had was trapping pretty low as well.

 

There is no way you gained 11 mph from those mods. I think that the comparison is flawed and isn't valid.

 

Yeah I would have thought the 2k4 would have ran a better time.

 

Yeah Jime I mean come on!

Those are great times though, can't wait to get my car the headers and exhaust coupled with intake combo to see what I'm gonna be running. Whether I drop a second and 11mph remains to be seen but hell if you did, awesome for you man!

Hope everything keeps running smoothly.

better breathing = more top end horsepower? who woulda thought?!?

 

I just stated what I did and the results.

Your opinion is flawed and invalid.

 

This is exactly why I don't spend a lot of time on this forum. You are comparing apples to oranges. You wouldn't make a great scientist. A 92 mph trap is poor out of 3.5 Maxima. The 1/4 mile registry is down, so I couldn't do research. I am relying on memory and the fact that my friend ran her Alti 3.5 auto to consistent 96 mph traps her first time at the track. I don't think I have seen a 103 mph trap out of a 3.5 Auto Maxi. I really don't feel like arguing, but riddle me this, do you realize how much hp it takes to gain 11 mph in the traps?

 

Maybe one of us is missing something here. Jime is comparing his times at the track with similiar temps and humidity. The only significant difference between the track outings were the addition of intake and exhaust mods. Slicks were present for both days. So he is certainly comparing apple to apples. As far as the trap speeds, I don't know enough to add to that part of the discussion but the ET's seem very valid.

 

It takes a lot of power to add 11mph in the 1/4 mile. How much? I don't exactly know. I know this though, it took ~11 peak whp, an extended rev limiter, and an additional 20-45whp/wtq from 5700-7000rpms for me to go about .3 second quicker and 2.5mph faster in the 1/4 mile.

I know that a stock LT1 F-Body 6 speed makes about 260whp/290wtq and does 14.0s@102mph on average. The 80lb lighter LS1 F-Body with a significantly longer and stronger powerband makes about 305whp/310wtq and does 13.5@106mph on average.

My friend's 02 Mustang GT with 4.10s and exhaust work made 250whp and did 13.6s@101mph with 2.0 60 foots. With the addition of a Vortech SC, his GT now makes ~370whp does 12.3s@112mph with 2.0 60 foots.

Like Jime said, he's just reporting what he sees at the track. I can't dispute that.

On numerous occasions at my track I've seen differences of over 3mph between runs on seperate weeks. Nothing had changed with the car, the ETs were ***** on, but the ending 1/4 mile MPH was much slower. I attribute this to problems with the track equipment.

 

By definition, an opinion cant be invalid.
