374 hp with 290cc injectors..???

 

pics

 

damn boost now...congrats, i can't wait to see what times you put down with this setup

 

thats what it says..want run files? pics of injectors?. i maxed out my injectors around 4.3k@ 305hp,the afr was at 13.0.

pics for what theyre's a video,or pix of the setup.
my afr was at 14.6 ish at 374hp

 

wait, aren't you supposed to dyno in 4th gear?

 

pics of the setup

 

i did 3rd. ill do 4th after the 440s

 

heck yeah, my favorite max just got even more favorite, didnt think it was possible...good stuff

 

any pics of the engine bay bro?

 

That is really lean. Don't get in boost too much before you get those injectors imo!

 

nicely done

 

omg u are going to blow the hell out of that motor if u dont get some decent injectors.

 

14.6 is lean for N/A....

 

You finally did it! Pictures of your turbo setup would be great. O and I have a set of 440cc injectors. You need them badly.

 

lol, well here's the fun part... i was enjoying it for about 4days like that before i found out it was that lean.. i had NO idea i was making that much power so didnt think they were maxed out. Got 440ccs in now and the car is between 10.5-11.0 WOT.. too rich now. i want around a 11.8-12.0.

Any who it keeps breaking up around 3500-5000 then clears up and burns thru 3rd and half of 4th gear.. was on the way home...cruising.. got onto a little bit...... MBC=FAIL, no tune=FAIL, oil leaking past cylinder 3 spark plug gourmet=FAIL.. eased on it in 3rd.. built up to about 6-7psi..coupler blows off..i hear a noise......connecting rod is doing a cha-cha-slide in my motor.....

im going with a EBC next.. my boost creeps TOOO much now with the MBC. i have the MBC alllll the way down. and the load screw 2turns from completely out of my WG and it still creeped to about 12-14psi... i guess the injectors helped with that or something.. Anywho. motor is under warranty.. should have the other DEK in by weds. then itll get a TUNE before my foot even touches the pedal.lol


i figure the car was between 400-440whp @ about 12-14psi before she pooped on the stock DEK
my words of wisdom.. EBC>MBC ..... too rich=FAIL as much as too lean.. TUNE is the key..

 

Sorry to hear that. Tuning is good.

 

ahh, dont worry, i actually laughed when it blew.. its been a few motors since i was upset when it blew.. i get angry at broken trannys now.. the only part ill dislike is the weather outside it suppppper cold.. but atleast i can wrap the feedpipe now and fab up some solid motor mounts..

+1 on the tuning but ill admit when i was wrong and will say, i just couldnt resist it.. it feels soooooo good.. i mean loosing track in 4th with 255.35.18s up front is amazing..when i dynod at the supra meet.. the BPUs were like lol

but now that i got my itch for boost out the way.. i can hold off for a tune

 

That motor blew faster than I thought. Sorry to hear about it but you need to learn more about tuning and how to treat a turbo car. Don't take my tone as getting on you, I'm not. Most people run a 38mm wg but if you get on it alot you might want to go with a bigger one. A smaller wg actually helps boost creep because it is not bleeding off the exhaust fast enough. Were you in 5th gear when it blew? I know on the 350z site some of the engines blew when they hit 5th-6th gear. I try not to maintain much boost in 5th gear, but I'm not a track man, just daily driving. You can still get boost creep with an ebc because they can malfunction, I noticed the quicker you get on the gas the quicker the spike, so I don't stomp it like a mad man, especially untuned.

 

no offense taken.. i know how important a tune is and how to treat a turbo car..just had to try it..been waiting on boost for 3years.lol.. motors are just a dime a dozen to me. The statement about going to a bigger WG ill consider though. i do play from time to time. and still am learning little but little about cfm's, and important ish that i never would give .2cents about when i was N/A.

it blew off in 3rd though.. but i noticed at about 75-80mph in 4th or 5th.. if i dont ease into it, and just got WOT, it creeps and blow couplers.lol

but with the EBC, i plan to set it about 2-3psi lower then i want so if it spikes, it wont rape the motor again. i also do slow shifts now now i have power and boost, no need for fast shifting. so i baby the throttle cracks but just need the tune.

 

When is the new engine going in? You need to get that car to a track after it's tuned!

 

if i have some good days at work, ill have it in 2-3days from now.. i dont have air or a lift.. just a gravel driveway, floor jack and hand tools but.. ill try to get it in and tuned so i can come with a few other locals to the NC track meet sunday and MAYBE run.lol iv still got to try out the new 2step module i got..check it out. was about $118, google N2MBperformance and its called a WOT BOX

 

That would be awesome! Yeah you can use some of those boxes to set an ignition rev limiter (instead of fuel cut) and no lift shifting with boosted cars.

Good luck getting it together in time, the track meet Sunday should be the biggest maxima track meet since maxus!

 

wow. pretty cool. minus the blow up. What kind of MBC are you using? lower end ones seem to boost spike. I never had a problem with TurboXS or Hallmans.

 

a Forge Motorsports.. supposedly pretty reputable...

 

wow crazy. well at least you work fast so i bet it'll be done by the weekend lol

 

where are you tapping your wastegate vac line @ ?

 

The red garage is available. And it has heat .

 

Hmmm. Bearing knock huh? Sounds like you may have detonated it a wee bit too much.

 

thats sucks, are you going with another dek or 3.5 this time

 

Ummm, isn`t 12-14 psi a bit much for a stock motor. Mines dynoed at 9.5 psi. Its been a rule of thumb anything over 10 psi, watch out (on a stock motor). But I could be wrong. Good luck new one thou.

 

It depends on what turbocharger you're making that 10psi with, more than the actual pressure. What killed this engine was lack of fuel. I'd also guess he could use some way to control timing before it starts getting warm out again as well.

 

well im goin with another dek until i finish my 3.5 build.. im also goin to use 2steps cold instead of one step, a EBC,EMU and j&s safeguard..will also bring the timing down.

 

"boost" line on wg gets "T"d into the sidr of the vontroller,the 3rd leg goes to the charge pipe.. vaccum line on wg goes yo yhe bottom of the controller

 

You live in Florida, right?

I bet you'd see huge benefits most of the year with water/meth injection. Set it up to only spray under boost and keep the tank topped off and you will be much less likely to detonate. Just throwing ideas for later!

 

hes part of the dc/md crew. Jaypees bro actually (right?)

i hope you get this thing running again soon. were u planning on coming down for the track meet?

 

correct and yes

 

yo aaron, how u gonna run the wot box.....b/c we are both 5spd swapped and we have no clutch button to have the clutch depressed to start it..how is the step going to work?

 

Vq35 and vq30 is the difference. More than likely it's always tuning but even still it seems like vq35s are more picky than the 30. They seem to blow left and right on the 350z forums. It's rare for a vq30 to blow.

 

you should have it and if not just add it

My max is a auto to 5-speed and it has the clutch button, cruise, etc
