Local track opened this weekend so I spent Saturday there! It was hot (for this time of year), about 75-80* with little to no humidity.

I only got 4 runs in, a few 14.0's and 14.1's and a 13.9:

I was planning on a 13.9, but didn't think it would be that tough. Racing this car is totally different now with the supercharger. Haven't figured out how to launch yet. I'm just using the stock tires on my SE wheels, so I only expect 2.2 60's (I was getting 2.1 on DR's last year). I couldn't get below a 2.3, which bothered me.

I also took my time on each shift making sure not to miss. Its not worth busting a tranny to gain a half a tenth...yet.

I'm gonna race her a few more times, then install a SC CAI, ACT clutch. After that I'm gonna start dropping pully sizes!!

For reference, I ran a 14.54@95ish NA and a 14.07@99ish with a 70 shot of nitrous (which of course wasn't used this time).

 

Are you running the stock pulley?

 

if thats stock pulley thats excellent!

even though no one has beaten delos run of 13.3@ 103 on stock pulley

 

Sorry, stock pully.

13.3? Wow. Even with a killer 60' time I can't see bettering a 13.7 with the stock pully.

Was he intercooled at that point?

 

Also forgot to mention, the track was GREEN. New pavement, no rubber. Times will get better later into the season.

 

nope.. just stock pulley.. i think matt said delos was power shifting. All he had at the time was a stillen body kit, wasn't even lowered. I think it was on street tires too.

must be the power of the white maxima's

 

No exhaust work?

That's nuts, I can't imagine how he did that...

 

i think he had a greddy catback and a cattman y pipe, but only he can tell, i can't really assume.

he needs to get back to the track now, seems like he is all pimp with his nitrous setup and 19's lowered and all

 

Good Job!

 

Nice runs. How is the traction in 2nd?

 

Traction in 2nd is just fine. Launching shouldn't be more difficult because I'm not making any more power than NA under 3500 RPM. So I get off the line ok, but once I hit 4000 RPM or so in first I have to feather the gas to prevent spin/hop.

Like I said, I took my time shifting and didn't hammer it into any gear. I bearly was chirping 2nd. I'm sure I could pick up close to a tenth with more agressive shifting, but its not worth its yet.

In addition, I ran with a full interior, only taking out the spare.

 

Nice times on stock pulley. Sprint a 13.3 @ 103 on street tires???Thats a 1.8 60' or better to achieve that time on street tires

 

Now we'll see what a stock pully and MEVI can do.

 

get the jwt ecu and you will be smokin. I think to fully benefit from the mevi you need a higher rev limiter. Good luck

 

Not when boosted. SC + MEVI = lots-o-power.

NA guys need the ECU, yes.

 

Whoa! Congrats!

 

 

 

Just 2 little seconds behind you.

 

sweet lets see it

 

Yep, you are right. Delos was still on a stock pulley. He had a full exhaust and the usualy bolt-ons. He had a pic of his timeslip in his sig (back in the day).

 

Wow. I can't even imagine how I'd get 3mph higher trap speed. What track was this at? eTown?

Realistically speaking, I think I can get a 13.8@101 out of the current setup.

 

I am not sure of his trap speed but I just think he has a freak car. hehe. I know he is also on the bottle but has yet to squeeze.

I', pretty sure it was at E-Town. A lot of us run our best times at E-Town. I guess its the fact that its so well kept (NHRA track) and its @ sea-level.

I'm sure you could muster better then a 13.8. If you perfect your launch, figure the given shift points, and run some D/Rs I personally think you have a 13.7 - 13.6 run with traps around 103mph or so. If you consider running a full 3" exhaust, that would yield about another 1/10th or so. If you want to get into the finer grain of things, tiem for a S-AFC for you.

Either way, a 13.9 is VERY good for a S/Ced Max with a stock pulley.

 

Well, we'll see. DR's suck, and I can't imagine they'd help. I have of 15X7 RX-7 wheels sitting in my garage waiting for some slicks, but I don't think I need them until I have a much smaller pully on there.

I know I'm way rich (1350* EGT at the end of the 1/4), but again, I don't think I'm going to invest in tuning it until I up the boost, otherwise I'll be re-tuning/dynoing more than I'd like. I plan on going through several different pullies over the course of the summer. I'm interested in actcually SEEING the gains of each. My plan right now is 3.33 next then a 3.25....and who knows after that. Although, I plan to stop there.

By the end of the summer I want to be running a 13.5 on street tires and who knows on slicks. Between the MEVI, ACT clutch, and (I plan on) a 3.25" pully, that should be more than obtainable.

Didn't help that I had close to a half a tank of gas either.

 

I'm surprised to your MPH is only in the 100mph range. Your 1/8 MPH is a strong 80.5mph and then it lays down at the far end at 100mph which means you're only gaining 19.5mph in the last 1/8. Even before my VI, I was gaining 21mph in the last 1/8. Like you said, you must be running really rich especially in the top of 3rd and 4th. The VI should help out a bit, but if you got JWT SC ECU program with the 7000rpm limiter, you'd be seriously hauling. I'd think you'd gain 4 mph and drop .3 with the ECU/VI.


Dave

 

Well, I was really careful not to f-up the 3->4 shift, as that's the one I tend to miss. That combined with the richness can't help.

I did have one trap of 101.X, but due to the launch it was a 14.1. The 13.9 came with by far my best launch of the day (which is really sad).

Next time I go to the track I'm gonna use my 17's. I figure I can launch WORSE than I did on the 16's, and I should have a little better top end.

 

Doesn't work in a 99, does it?

I think the MEVI alone will make a world of difference in the top end of the track.

 

matt's got a 98 with an aftermarket ECU i say it should work

 

Good point. One mod at a time though...

 

Great stuff Eric, glad you got it all together and working. No where to go but up from here.

Hope to meet up with you some time this summer. Going to try and get to Cayuga on sunday for a run.

 

I forgot you have a 99 now. Unfortunately the JWT ECU won't work in the 99. The MEVI should help out a slight bit in the 1/4 mile, more so than an NA Maxima. Too bad you can't run the ECU though, you'd be a lot quicker with that 7000rpm limiter because you would be able to stay in the 3rd the whole way.


Dave

 

JWT ecu in a 99

 

you sure about that buddy?

 

The question is has he driven the car since getting the ECU? From what I've heard about this car, it's in peices right now. It's been my understanding that the 97-98 can run the 96 JWT ECU, but the 99s are SOL because they share they're box with the 00+. I think the ECUs look completely different two.


Dave

 

no

the 97 can use the 95/96 ECU..

the 98 - 99 cannot due to digital odometer and other knicks and knacks.

However..

Matt has a 95/96 ECU in his 98 Maxima so that kills that theory.

my cousin's 99 SE has a 4th Gen ECU. How do i know? 5th Gen ECU's don't have screw's on them, however i pulled my cousin's codes.

 

99 is kinda a 4.5 gen ECU. They are physically a little different...I may try to use my mom's 97 ECU (stock of course) in my 99 to see what it does. That would clear things up.

 

nice times!

 

Ferhan's car isn't put together yet. Who knows. I'll call or email him.
