Fuel Cutout while spooling
#1
![Question](https://www.miataturbo.net/images/icons/icon5.gif)
I have just finished my project of adding a GT2860RS Turbo and a custom 3in exhaust on the car. I have added a BOV right before the manifold. I started the car and it runs fine, but on a road test the car seems to lug a little and at about 5250rpm it falls on its face and cuts out. I dont know if this is a tuning problem, vacuum issue or what. Any help in this matter would be great. The car dyno'd at 248.7hp and 220 ft/lbs even though it huccups at 5250rpms. I cannot get the car to pull through the rpms correctly. Please advise. Thanks!

So far I'm running off the stock ECU, no piggy back yet. I am in the process of adding 550cc injectors and a fuel pressure regulator to cut the injectors back some. I dont know if the car is leaning out too much while building boost from low rpm's or what. I know im going to need some type of fuel managment, but I dont know what is the best for the money. Im new to this game. The car will run fine through 1st 2nd and 3rd, but it will cut out in 4-6th. It doesnt really matter what boost levels im running, ive tired it all the way from about 11psi to 22. Still cuts out. I also cannot get my BOV to work, my stock diffuser valve is too weak and leaks at idle, but the BOV doesnt function and I have some bad compressor surge.
Any help would be awesome.
A few minor tweaks and this car will have 300+ whp easy.
With that hiccup at 5250 it still had 248.7 whp at 8psi

Holy **** guys, Im sorry I know how to make a car perform without spending thousands on fuel managment. Yes, I have documentation of the car running 250whp without fuel managment or bigger injectors. Give me a break here, Im no idiot, and dont be jealous to say its BS. Get over yourselves, im looking for help here. I trial ran the car at 22psi, Im driving it at 8, read and understand before you jump in, how about that? Go ahead and think what you want, Im the one driving the car.
Thanks for the help, wait, no one offered any. Ha.
I build cars, I moved from 302's to a miata. I was thinking over 500 hp in a heavy car wouldnt be as fun as a light car wth a little over half that. Obviously big numbers scare you.
I'll just stick with my previous intuition and get bigger injectors and a fuel pressure regulator.
See you Ladies on the road. Actually, I hope not for your sake

Oh, so you think you know how a car runs?
Last time I check a turbo is always making boost, and at idle the BOV or Diverter valve is either releasing to the atmosphere or recirculation. And if it leaks at idle the car will stall out, or run like crap.
Maybe you should know what you are talking about before you jump on the bandwagon of these other criticizers

Real world building and testing experience guys.
Im new to building tuning a turbo car, thought this website was all about helping each other but I guess its all about who thinks they are cooler. Welcome back to highschool for some of you. Maybe you were the kid I used to make fun of, or the ones that were jealous of me because I know what I am talking about and know how to perform.

oh smart guy you have a MSM, that changes things a bit. You have an ECU designed for boost....It also has a thing called a boost cut, where you can only run X amount of psi. IIRC, it's 13psi....

Is your car a 04-05 MSM?
<edit> by the time I was able to hit submit, the answer was already given
In that case, there still is not 250 whp worth of fuel in those injectors. What was your correction factor?

04-05: so the pic suggests. and now his sig states it too. < edit, by the time i finished posting this ben edited his reply >
oh and 250 is not a big number, especially in a bloated MSM.
anyway, you can't just throw 550s in, your ecu won't be able to idle them. So you better come up with a better plan. So far people have failed on the MSM with the E-manage blue and ultimate. I've only heard of one person who has done a Megasquirt in an MSM, and yes it was successful.
Hope you have $2k to drop on a hydra or you are gonna need a lot more to replace the engine too.
I suggest starting the apologies now or find a new forum to get **** on by. You've already admitted you know **** about turboing a car, well there is no better forum to learn.
