Definately in for the flamefest when I read the title lol.. Way to back it up!
When my car was bone stock, with just dr's I would run neck and neck with mustangs timewise, (13.4-5) but they would trap higher. (06-08 mustangs)
As far as what people say regarding longevity, get a good tune and stay on top of maintenance, and your motor should last for quite a long time.
When I was thinkin about boosting my car 6 years ago, their was a few people that said, " don't do it, it'll blow up on the dyno" lol.. I just passed 110K boosted on 9-12psi, 140K on the engine. Although the car that rolled off the dyno 6 years ago would crush the car I'm driving today, thats besides the point
Good luck!!

 

Wow thanks for the input ^!

 

Starting to look like a car again, installed oil catch can, moved power steering cooler and made a bracket for it/ oil cooler.

Guess who forgot to drill and tap for their EGT gauge when the motor was out of the car..... **** me

 

Driver06-- so doesn't matter too much in mileage?? Boosting at most lower to mid 100k-ish miles is ok? I'm sure it's about tune for the most part but weakening the rods doesn't have an entire part of rods going, doest it? If they get weak , they get weak= snap. Then goes the VQ.

 

I wouldnt say mileage doesnt matter.
I guess think about your high mileage motor as a 90 year old guy. If hes been running 5 miles every day for his whole life, he could do it at 90 years old (just not as fast). Now take a different 90 year old guy that never ran, and ask him to run 5 miles.. I'm pretty sure that it woundnt work out for the poor bastard. Sorry, it was the best way to explain it
My motor has over 140k on it, but 100k of that was boosted.
Japanese cars are running for hundreds of thousands of miles today when properly maintained, so at 100k everything is broken it, sitting where its gonna sit. But if you have any parts that are getting weak or fatigued, your def. gonna see it faster if you boost it.

Cliffs notes: I wouldnt rec. boosting high mileage, but if it were my car I would absolutely do it!

 

Just need to look at it as loading. 100k miles is going to load rods. Our rods are tiny. Boost increases the load. So you're putting very high load (especially due to the rod stroke ratio on a stock vq35) on already thin and weak rods. High mileage stock rods are simply not going to handle it.


The only thing is most people think 400whp is 400whp. 400whp on one day on one dyno could be 350 on another and 425 on another. Also depending on how the tuner sets it up makes a huge difference... How quick boost comes in, how aggressive the timing is, how smooth the torque comes in etc.

 

Op--aweswome pic !! That's a huge *** oil cooler. How much oil does she have now-6ish quarts??

Driver--Ive known/understand totally what you're saying so doesn't friend. He didnt want it to happen but knew there was a risk for playing w boost from the get go. Just sucks so soon and it was his daily which makes it more of a bad ****-uation. But now it's just find another block and put some forged internals in her bottom end.

 

Tried to start her today, no powering getting to the fuel pump, doesn't prime or anything..


When turned one click my me would deck comes on no problem, once turned to acc position, the radio shuts on and off really fast... Must have a short somewhere. Any suggestions? Going to undo the doing tomorrow. Hopefully find out what's messing up. I installed defi boost/egt/oil temp. Aem a/f gauge. And a greddy turbo timer.

 

Meh, take the turbo timer off. Just don't go WOT 2 sec before shutting it off and you will have problems.

 

It's funny, I bet 100% of the people that saw this thread originally came here to flame lol

 

cant figure this **** out... undid everything i did in the interior, double checked wiring harness's on the engine, everything seemed to check out.. would swapping injectors cause this maybe??

 

Success!! A stupid mistake...


I'll post up pictures later

 

Sorry i've been a stranger guys, ill upload some more videos/pictures soon. Been working on the car more, got a new job position so lots of hours.




Question.... My aem uego is reading 10.0 flat under WOT (doesnt read lower ) Even since the day of my tune. Think its a bad sensor? ( purchased brand new ). Could a bad O2 sensor cause the car to run rich? I am going to take the car back over to Uprev next week or so to get everything checked, just curious on your opinions!

The video on the dyno was when the car was only at 273 hp, i wasnt able to get a video of the full effect .


VIDEOOOOO

VIDEOOOO

ANNDDD VIDDEOOOO
Good sound of the Tial





Shot of the gauges


Dyno sheet



398hp/335tq





I also picked up a new daily! My miata was toast after the hail storm we had here.

 

Because you are running Uprev, the AEM UEGO has no effect on your tune. You are still utilizing your factory O2 senors and MAF for fuel control (technically only the MAF at WOT). I would definitely get it checked out to make sure you aren't actually running that rich, though.

 

Came for the flaming. Good work OP, hope you get everything squared up so you can enjoy the new power.

 

I came to watch the flaming also, but I was pleasantly surprised.

Very nice job OP

On a side note I got input about adding boost when your over 100k, just by reading this thread.

 

I hooked up my cipher cable and monitored the car at idle and under WOT, 14.7-11.25..

Stupid *** uego is all over the place.

 

can see shiet bro

youtube those videos

 

^ I'll get on that boss.

 

Try these..
