T4 @ 9psi
3" cut out right after the turbo
MEVI
550cc DeatschWerks injectors
Z32 MAF
Stock ECU
A few gallons of 101 octane
No weight reduction at all, not even the spare removed
Street tires

Wasn't expecting very good ET's being on street tires, they were actually pretty sad. Was mostly concerned with trap speed. I only had traction in 3rd and 4th gear. Still learning how to launch the car without going WOT.

The two best passes

60' 2.323
330 6.116
1/8 9.027
mph 86.72
1/4 13.57
mph 110.94

60' 2.249
330 6.033
1/8 8.987
mph 85.58
1/4 13.57
mph 109.99

So, 111mph traps on 9psi

Put my $600 JWT ECU in for a run and only trapped 105mph. What a piece of crap, and that was on more boost as well along with the 7200 rev cut. I also got twice as much knock with the JWT ECU.

Time for some slicks and some 12's


**Edit**

Almost forgot, put the hurt on an LS1 Trans Am and a Saleen at the track. On the way home a TT Dodge Stealth wanted to play.....put 5 car lengths on him.

Nice traps Mike, yup time for some rubber.

congrats on the times, you make me want to remove that POS JWT out of my I30!!!

Nice job man. 13.5 thats good keep it up, definetely need some new rubber...

Starchild2K2SE

Nice Times Man! I can't wait till im boosted and goto the track. Im aiming for 12's also, much respect mang!

MAX2000JP

Very Impressive Mike. Those trap speeds are good for low 12's. Once you get your tuning issues solved and some traction, your car is going to be a beast. You, Brian, and Neal are going to make me do something stupid and add forced induction to my Stang.

Thanks, but I don't know about low 12's. I do need to get the AF ratio out of the 10's. Since I am running stock timing I want it around 11:1-11.5:1. I probably won't pick up too much power from adjusting the AFR, most gains are seen when going from a mid 11 AFR to a mid 12 AFR, not from a mid 10 to a mid 11.

I think with some cooler weather, at least a 1.9 60', traction in 2nd gear, and another 1lb of boost I could see 12.4-12.5 @ 112-113 mph. I am going to pick up an EBC since I am not seeing the full 10psi from my 10lbs spring, it should help me spool faster as well.

Royal_T

Very nice times Mike, keep up the good work. I say mid 12's when you get every thing sorted out. And next time you go to the track make sure you video tape it, I would love to see your car in action.

Nice traps indeed. I'd also like to see a video if you manage to get one.

What are you going to do about the JWT?

Blu

iTrader: (63)

I was thinking about running my car this weekend also but when I try to shift somewhat fast it stutters from fuel being dumped. How are you shifting to avoid this? I've got 65 more cc injector so I dont think its too much of a difference.

pawnstar12

good work mike i dont belive in weight reduction either....i always end up racing with @least 3 people in the car. lol

I30tMikeD

iTrader: (8)

I have no hesitation or sputtering. The thing I am most amazed about is that I have had no cold start issues at all, not one. This is with my fuel pressure at 50psi!!! Me and my brother are trying to figure out what is the variable in my car that is letting me run this set up so successfully. We think it might be that I am running a different injector application than he usually uses. The ones I have he hardly ever uses just because he does not have much of them. We are doing some test to see if these injectors have some slightly different charectoristics.

When I was running the stock injectors and FMU I would have a sputter/hesitation during WOT shifts. What worked for me was not letting off the gas completely between shifts. It is probably an issue of the ECU going from full load, to no load, back to full load and the fuel response. I have seen several other turbo Maxima's complain about it.

Royal_T

I also don't believe in weight reduction, When it comes down to it on the road you always have something in your car.

I30tMikeD

iTrader: (8)

I did not do any weight reduction because I was lazy lol, I am certainly not too good to start ripping stuff out to get that extra 10th at the track. But I would never drive around with stripped interior on the street.

pawnstar12

i say we drive i30's damit! not some raggedy ek hatch that no one cares if it stripped out

JAY25

iTrader: (38)

Can you please get a video of you going down the track waxing these cars please?

subs1000w

nice trap for 9psi your making alot of power

Boosted Maxima

Awsome! What track did you end up going to? US41?
I'd like to set a friday up here in the near future where the Mamximas from the Chicago and anyone from somewhat close area can go down and have a good time.
US 41 is a good track and they stay open till 1am which is great for taking your time making changes... talking with out the stress of haveing to get 100runs in in 2hrs before dusk like most tracks.
Anyway... Great accomplishment in all areas.. now go get some slicks and break your tranny

Seriously Mike, those trap speeds are truly healthy. I almost ran a 13.2 and I barely had 103 mph. So 112-113 mph is LOW 12s if you can get out of the hole.

BTW, were you on DR's or real street tires?

If you want slicks, get 24.5X8.5 M&H like Mardi had. His best 60 foot was 1.71 I believe, and you will end the 1/4 mile above 6000 in 4th gear.

slimer

iTrader: (13)

I'd be down for that Scott. Just let me get everything working properly first.

Mike, those times are pretty good, how hard was it to get traction?

I30tMikeD

iTrader: (8)

True street tires. 245/50/15 Dunlop Sp8000's. Sold my DR's a while back and still have not picked up another set of track rims/tires.

The reason I don't think I am good for low 12's is that I don't have the low end torque that you 3.5 guys do. With this set up I will always be a 2nd 8th mile monster.

mad-max98

iTrader: (2)

you have enough torque to lose traction though so you're good for street tires as far as slicks maybe you need that 60 shot off the line

Congrats Mike, looks like you got a healthy car on your hands. Now get some sticky tires and get your I30 into the 12's I don't know what I30krab runs, but it looks like you will be the first I30 in the 12's. Way to go.

nice times man...BTW what is up w/ the JWT? did you get them to admit the programming is fuged up or what? thats got to be irritating!

I30tMikeD

iTrader: (8)

I will comment when the process is over

stephenlc

iTrader: (1)

there too conservative, thats what all the 240 guys say. Some guys have made 30 whp and 20 wtq by just changing from a JWT ecu to another ecu.

Blu

iTrader: (63)

them being too conservative is not Mikes or my problem with the ECU. To this point I dont know wth is going on with there program. Just remember besides Hal all the quickest and fastest Maximas have been running JWT ECU's. That doesn't mean **** to me now especially after the crap I've went through with them but it shows if its right there ECU works well with FI cars.

FYI I asked for the race gas tune for the timing in my car

JClaw

iTrader: (17)

Damn right. Your second 1/8 mile was done in 4.55s on your best run. On my best street tire run it was 4.79s for the 2nd.

Jason R

iTrader: (39)

wow, nice trap speeds.

Brad92SE

iTrader: (9)

Holy crap! Awesome trap speed, Mike!! Keep up the good work. Next summer I hope to be running a similar setup with the 550's and Z32 MAF. That is, after taking care of my tranny. Hopefully we can meet up sometime, I still haven't seen your car in person with the turbo.


^^Scott, let me know when you are planning on going down. Hopefully I can make it out too, depending on my schedule.

MAX2000JP

Your estimated trap is indicitive of low 12's with traction. Factor in some weight reduction and IMO you should be right there. Your car is quite the sleeper.

Fred Allen Burge

What are you using for fuel management? FMU, SAFC,etc? I reread your post but didn't see anything about how you are controlling the larger injectors.

allen

I30tMikeD

iTrader: (8)

Not using anything really, I do have some small S-AFC corrections. The Z32 MAF flows about 80% more air and the injectors flow a little less than 100% more fuel. So the stock computer that is programed for the A32 MAF is seeing about half the MAF voltage it normally would and adding half the fuel it normally would so it works out. Since the difference in the injector size is larger than the difference between the amount of air the two MAF's flow my AFR's are dropped to a low 10:1. Certainly not ideal but safe for a boosted car. I can now use my SAFC and an AFPR to play with the AFR to bring it up to 11:1. Kinda of a hack way of doing it but it is working very well.

Fred Allen Burge

I see, so basically a "hacked MAF" without the hacking. I first learned about that technique on the 240sx forums, never tried it myself. What PSI do you think your fuel setup would be safe for and are you using a larger fuel pump?

allen

I30tMikeD

iTrader: (8)

Using a Walbro 255hp.

I think the fuel set up would work fine for more boost then I will ever see. I don't see why it wouldn't be good till the MAF is maxed out.

The issue with the set up as it is now is timing. I won't run over 10psi on stock timing. I have had a little bit of a detonation issue at 9psi in the end of 3gear in the heat.

Dave B

A big congrats Mike. It's good to see that your I30 is running really strong. I think mid-12s will be easily attainable. Is the I30 still a sleeper?

JClaw

iTrader: (17)

I would call any I30 trapping 111 mph a sleeper, and I think he's still got his 15-inchers (i.e stock-ish looking).

I am interested in the rims, 22" diameter is pretty short.
