I am too tired to post all the details right now, but I got a personal best 1/8 mile, 1/8th mph, and 1/4 mile. My top end was off tonight for some reason so my 1/4 trap was lower than before even with more mods now. When I get that sorted out I think I can run a 14.0-14.1 @ 99+mph because there is still some left in the car. My best two slips were:

60ft: 2.195
1/8: 9.221
mph: 79.44
1/4: 14.287
mph 97.50

60ft: 2.208
1/8: 9.254
mph: ...
1/4: 14.261
mph: 96.90

Check out that 1/8th mile mph, I think it is the highest I have seen out of any N/A 4th gen , manual or automatic. My previous best was a 14.44@98.19mph. Tonight I was only gaining 18mph from 1/8th to 1/4 mile, which is a little lower than expected. I was gaining around 20mph before. I will post more details tomorrow.

Larger filter? Are you still using the JWT intake? I can't imagine the car needing a larger filter than what comes with the JWT Pop Charger. It's 6 inches in diameter damn it. =P Great times. I think my A/T solenoids are dead. I've never had great shifting with my Don's VB mod. The car shifts faster at part throttle than WOT.

where did you buy the lightweight battery ? was it an odyessy.. in looking right now for 1 !!

wow, is the pathfinder throttle body a good upgrade?

GOOD JOB BUD!!!


sweet ****....why did you swap your Gforce for JWT??? just curious....

96sleeper

iTrader: (4)

I got it on closeout, its a hawker battery. Same as a dyna-batt without the high price. It was pretty cheap, I will try to find the site that I bought it from and send you a pm.

7000rpm redline. The g-force was great but with the MEVI I needed more rpm to take full advantage of it.

That 1/8 mile trap is simply amazing. Maybe your VI was not activating in second or third??? Do the autos hit 3rd in the 1/4 mile? Anyhow, I used to have a harlan and it would open in 1st, 2nd, but not 3rd most of the time. I pick up 21mph sometimes 22mph in the second 1/8 with my JWT-ECU and VI. I am very impressed with that 1/8 trap!!!!

I have been racking my brain as to why my mph fell off on the top end. I am near redline in second right as I am crossing the 1/8th mile mark with my smaller tires. My VI just opens in third gear as I am crossing the 1/4 mile mark. I have a LED wired that lets me know when it is opening correctly. I had my VI set at 5000rpm and I trapped 97.xx 4 times in a row. I changed it to 5300rpm and my traps fell to high 96mph speeds. I think that my knock sensor may be pulling timing in 3rd gear and causing the mid range to suffer there. I also have the pathfinder TB and ran it for the first time. My A/F ratio could be screwed up because of it, or maybe the JWT ecu is just not as strong as the G-force besides the higher redline. I still have it in the car, I should have plugged it in to see if there was any difference. It is weird that 1st and 2nd gear are fine since my 60 ft and 1/8th mile were good, 3rd gear just seems to drop off. One other reason could be that is was pretty cold and tracton was no good. I was spinning most of the way through first and into the shift to second. I thought that spinning was usually good for mph, just not ET? I am still trying to figure it out. I plan to dyno soon and get my A/F ratio checked out. Any more ideas?

I don't brake torque at the line which is what most people will tell you what to do. I do a small burnout to clean off the tires. I stage and then on the 3rd yellow, I give it gas for a split second as I am still on the brake. It is almost like both feet are moving at the same time. gas pedal going down, brake pedal moving up. It is hard to explain, but it is called "flashing" the torque converter. Instead of brake torqueing you are trying to get the converter to catch right as the car is starting to move. When you "shock" the torque converter like this it lets you leave the line at a higher rpm faster. Hope this helps, it is hard to explain.

nice times... kinda brings up my faith in my auto

Congrats and wicked times as usual

Did you run octane higher than 93? The reason I ask is both Mike and myself have run higher octane and have gotten some good results. Overall, on the days I've ran race gas I've usually been my quickest. I did run my best without race gas, but my MPH seem to have suffered a bit in the topend. That day my best was almost 98mph. With race gas I've done as high as 99.5mph. Overall I usually gain high 20mph in the final 1/8th without race gas and high 21s with race gas. My highest is 22mph which is an incredibly strong for an NA motor.

Try a mix that brings octane up to around 95-96 and see how you do. I'm starting to believe that the JWT ECU may advance timing quite a bit and if you don't put some higher test gas in there, the longer gears may experience more detonation and knock retard. Many of us are running higher mileage motors which means our compression is probably more like 10.3-10.4:1 instead of the factory 10.1:1 because of carbon build-up in the compression chamber. Higher compression = more power, but also = more detonation.

I was going to go to the track tommorrow, but the station I get 100 octane from is closed on Sundays and tommorrow is the last race day of the season. It's going to be 55, sunny, low humidity, and good pressure

Sweet times Get a TC and slicks and stop mucking around in the 14s and run some 13s.

P.S. My fastest 1/8 mile trap speed doesn't begin with a 7

96sleeper

iTrader: (4)

Dave, I bought a bottle of octane booster that said it would boost up to 20 points in 10 gallons of fuel. 20 points=2 octane rating so I was possibly running 95 octane, especially since I put it in 4 gallons of fuel. Other than that I am still stumped about my trap speeds. I am not as happy as I should be about a new personal best because trap speed is more important to me than ET anyway. I honestly thought I would see some 99mph and maybe even eek out a 100.xx mph trap. Any other thoughts on the loss of speed?

Nealoc187

iTrader: (23)

The trap speed is always the first thing I look at on my timeslip too. ET just shows me whether or not I fcked up, trap speed shows me if my car is running right. What RPM switch are you using.

deezo

HEHEHE!!!! This is good stuff! Congrats!!!!!!!!!!!!1

Nismo87SE

In that case your going to have to go the toulene, xylene method. I hope you have access to some DR's or borrow some slicks, it would be nice to run that elusive 13.9 on the last race day

I am using the Harlan switch, but it has never given me problems since I got rid of the relay a long time ago. I have a LED rigged up in the cabin to let me know if the MEVI is opening and the light came on every time.

I30tMikeD

iTrader: (8)

I would bet it's the lack of race gas and the 70mm TB. I would not trust those octane boosters to give you much. The TB could very well be throwing your AF wacky. Is it possible that your LED would light up when your desired rpm is reached but the harlan still flaking out? If you think it is possible I suggest checking the switch after drive when the VI is activated a few times. If it flakes out it will be blinking at you. Don't turn the car off before you check it, it will reset if you do.

When I did not use race gas I was only gaining 18-19mph in the second 1/8 mile

96sleeper

iTrader: (4)

I guess that could be it. I never used race gas with my g-force ecu and I never had any problems, but maybe the JWT is different since it goes to 7000rpm. I am still going to try to dyno in the next few weeks and see if everything is normal.

SXN

I think its the new throttle body, not the new ECU

Nealoc187

iTrader: (23)

In what way is your MEVI LED hooked up. Is it just running off the RPM switch or is it physically hooked up to your MEVI so that when the bar swings open, the LED illuminates? My harlan though it was working fine, the switch was lighting up at the right RPM (which could be the same situation you are in). All indications were that the switch was opening fine, light was working, etc. Only way I knew it wasn't is that I was slow and when I popped the hood and tested it. The light will illuminate but my MEVI wouldn't open.

Dave B

Man, I must be the only guy with a MEVI that can hear his MEVI open in 2nd and 3rd gear. On my car there's a pretty substainial change in the intake tone at an indicated 5500rpms (5400rpm switchover).


Dave

Nealoc187

iTrader: (23)

I can't hear it open. At 7k rpm I can tell whether it is open or not because of the tone, but I can't detect a tone change right when it opens.
