Well my first dyno was bad, i didnt get TQ reading, didnt even get a/f. Now i got an official dyno results. Previous dyno was at 5psi untuned and made 230whp, this dyno I am at 7.5psi tuned to 11's, and meth injection(on the last run).

1st 255.37whp and 264.25tq a/f was about exactly 12 flat

2nd 256.77whp and 263.41tq a/f was same as above

3rd 258.34whp and 263.55tq Used the Meth injection and a/f was about 11 flat, I can add more correction with the meth and get even more power out of it.

Nice. I can't wait to see 300+ numbers come out of this thing on 10 PSI with some good tuning.

nice results...makin me think harder about this too. wonder what numbers on a 3.5 would look like.

pretty good results.

Glad its all finally working out.

Looking forward to see 300hp+ from your setup

Thanx all. I just put up the boost to 10psi with the meth but i heard to much pinging. so i lowerd to 8.5psi and pulls very strong but I think i herd pinging as well just not as much. I am going to order a larger nozzle for the meth.

Your timing might be too advanced since you pulled so much fuel back.

are you still on the Z32 maf? I'm guessing maybe your on stock with -15 points of fuel correction.

NmexMAX

iTrader: (22)

Timing is advanced too much. That can be seen by the 'choppiness' of the curve. Also, why stop @ 6000?

streetzlegend

iTrader: (8)

MDeezy, i lowerd my fuel pressure so that now i have less corrections. my timing should be less advanced, the most correction i have now is -10, which should still be advancing a lil bit, for now im going to leave my boost at 8.5psi (put it up this morning) 10psi i was pinging too much. so hopefully next weekend i can install the emanage blue, and go for 10psi. also, i am using a VG maf which is the exact same as the z32 physically, and i dont seem to be maxing it out at all. so i guess that maf is the same as the z32.

MDeezy

iTrader: (27)

yea with less corrections you should not be as advanced as before. With the e-blue installed you'll be able to monitor a lot of what the car is doing and get a good idea of what exactly is going on.

the I'm not to sure on the VG Mafs. I was told the J30 Maf is identical to the Z32 maf.

looking forward to more info once you get the blue installed. Do you plan on connecting the WBo2 thru the eblue or datalog that seperately?

iTrader: (8)

MDeezy, I plan on hooking up my WB02 to the emanage blue so that i can log the a/f in relation to rpm instead of time how i have it now. also, the VG maf does infact have a different serial number than the z32 maf, but the body of it is exactly the same, even the plug is the same with the same wires, you can basically put a VG maf into a z32 without any problems or changes in wires. Maybe they are the same, i am not maxing it out either so thats good.

The choppiness is actually because of the methonal injection not because of the timing, my other two runs without the meth were VERY smooth. but either way, yea i still have to take back timing. and i didnt want him to take it to limiter, dont kno im just paranoid like that lol

Physical dimensions of the VG Max Maf and the Z32 Maf might be identical, doesnt mean the hot wires are "tuned" the same way. So yea they might flow the same amount of air, but not necessarily read the same output, you get me?

But w/e it seems that at YOUR boost level, that VG MAF is working just fine and its not being maxed out. So for someone that wants to keep their boost in the 5-8.5psi, it might not be necessary to get a $100+ Z32 MAF if a 3rd gen Maxima Maf seems to work just fine for that.

iTrader: (8)

I never said the VG maf hotwire is tuned the same way as the Z32. But w/e it is, its not maxing out compared to the 4th gen maf.

sorry, I meant to write that as a FYI for the n00bs, lol

When i still had my stock maf (3rd gen maf) it maxed out Right at 271 whp.. it was just maxing out when i dynoed that.

streetzlegend

iTrader: (8)

hmm interesting. I guess i'll have to see how it does when i put up the boost. How will I kno if it is maxed out? I already put up the boost about 1psi from the dyno day, at WOT the maf voltage reads 4.7 I assume it maxes out at 5.0v so i still got a lil more to go.

How would I know if it maxes out? Would I lean out all of a sudden?

MDeezy

iTrader: (27)

4th gen maf is said to max out at 450hp. but swapping in the z32 to get a richer fuel mixture is (i would think) is more the main reason to swap maf's

300-350

nismology

iTrader: (8)

A32 MAF is good for 350 BHP.

streetzlegend

iTrader: (8)

what about the 3rd gen maf? cuz im over 350, specially now at 10psi and not maxing out yet.

MDeezy

iTrader: (27)

i stand corrected

Kevlo911

iTrader: (36)

Most turd gens dont make that much power so we don't know

But it is prob around that. Cut up your 4th gen maf and put it in a bigger housing or get a z32/j30 maf

ok I was always told the z32 maf will help lean the car out with larger injectors so you would not have to make such larger corrections.

Ok I made about 260whp on my third gen and the stock maf was right before maxing out!
