How long have you been boosted?

Just curious how many miles you guys have put on your Max's supercharged or Turbocharged. Please include mileage, psi you run, and supporting mods (fuel, etc) your running. Seeing a couple 300-400 HP maxima's w/ stock internals on the board. Dunno how long your motor will like that kind of power. Although I got an Eclipse I have put 10K miles on my car w/ my turbo kit at around 8 psi. Blew one motor already on the dyno when I spiked to 10 1/2 psi.

Re: How long have you been boosted?

I have about 1500 miles on mine - bout 2 months. I'm at 74k on my motor, hitting 11 psi. Vortech FMU, Walbro pump and 8:1 disc with a sard fpr @ 32 psi idle is my fuel setup. At peak boost, EGT's are still slightly rich The maxima is no eclipse, it can take a beating.

Been blown for about 6500 miles on the original 135,000 mile motor with the 3.33 pulley (9psi), stock fuel pump and injectors, greddy bov, and full exhaust (y-pipe, rt cat, greddy cat-back). I've been getting a few lean codes like every other week. I just received my s-afc and planning on going for a dyno tune.

Juiced it from 15k-25k, boosted 10psi from 25k-35k, 15psi from 35k to now 51k. Compression is holding up fine, oil reports are great. Check my web page for mods.

Impressive guys, especially MardiGrasMax w/ almost 50 K miles of forced induction. Good to hear your engines last longer then mine. Although I expected that since you guys got an extra 2 cylinder. BTW seximagtr "The maxima is no eclipse, it can take a beating", might be true for my NT Eclipse w/ a turbo kit but definately dont start me about the 4g63. I know about crankwalk but the 1G's can take a beating and are so fast w/ barely any mods. Also your turbo kits cost 4G's and mine was 2G's so I got a little extra $ lying around to rebuild and then what. Dont wanna start flaming but Im asking a simple question so I can learn more about Maxima's to see if I want one. No need to put down my car.

Re: How long have you been boosted?

Supercharged at 3000miles and I am currently at 72,000 boosting between 8-9.5psi (3.125") on 6:1 still and haven't had any major problems besides needing a new clutch at around 15K. I think I need another clutch again..

~33K miles to ~63K miles with SC with different pulleys (3.25, 3.125, 3.0, 2.87). Boost varied from 10-11 psi. Fuel management was 8:1 Vortech FMU and A'PEXi S-AFC. 288 whp in auto form (w/3.125 pulley... tuned) and 301 in manual form (w/2.87 pulley... untuned).

~400 miles with TC. Highest boost seen was 5.6 psi at about 4300. Fuel management is Cartech FMU and A'PEXi S-AFC.

35k to 42k. V2 SC with 3.33. so far I see 7psi at 6000rpm.

with the 2.87 pulley, I see 8psi at 5000 rpm. Havent take her up near the red line yet.

no fancy electronic accessories for me. I just have a stillen y pipe and gauges to support it so far.
