ok so my standard turbo let go at 9psi sounding like a cop siren. got the boys at united fuel injection to have a look and found 1 of the impeller blades was chipped in the corner (attatched pic) caused by the internals failing (probably bearings) now before i put a new turbo in is that normal for a standard turbo to let go. usualy the turbo destroys itself or when it lets go its at 12+ psi so would there maybe be a problem in my oil lines or something? or is it just the turbo.

ok so to my original question. i rang up hypergear and im thinking of getting a standard highflow for $960 (240rwkw turbo using bush bearings)

-will it be safe to run this turbo on 9, 10 , 11 , or 12psi or however high i can go without the standard ecu hitting boost cut/rich and retard running an safc???

the car wasnt realy set up for an aftermarket turbo as ive still got the standard clutch, injectors, afm and ECU, the car made 192kw with the standard turbo before. ill be happy to run similar boost as before and make the same power (im not trying for 240 on my setup) just wanna make sure the ECU will be able to controll the slightly bigger turbo with steel wheels safely. cheers fellas

Aftermarket ECU all the way mate. Why do people try and cheap out on power increases in their vehicles? It only ends up costing you more down the track. Power = money and there's no way or loophole around that or everyone else would have done it already.

Yeah just run the same boost on the high flowed turbo. That should make 200-210rwkw, that should be fine on the standard ecu.

Then once you get some cash: injectors, fuel pump, nistune and clutch

Or you could just buy another stock turbo.

it depends what actuator is on the turbo

this spring is the minimum boost you can run on full load

if its got a 10psi spring you may find 10psi on a larger compressor wheel (as its a highflow) will be enough to trip out the ECU protection and cook the clutch

Good point, I forgot about the actuator. The hypergear hiflow i believe comes with a 14psi actuator so you definitely couldnt use that.

its the standard highflow for $960 not sure what he does with the wastegate ill ring tomorow and ask.

the reason i wanna stay with the safc is coz i dont have a spare $2000+ and i dont wanna make the maximum power possilble just wanna get it running safely will be happy with 180-200kw. just to get the car back running again im gna have to save every penny for 2 weeks and not go out at all lol.

im going for cheap and reliable, i can leave out fast for now haha

So just replace it with a R34 NEO turbo or something then?

Less than half the price of a hi-flow that you will never use.

i got the exact same as you, the high flowed turbo from hyper gear $960 one, im running 12psi fine before that, now that i got it in it spikes 14psi...and ever rarely cuts out...btw running a stock ecu also...but mind you i needed a fuel pump next day.

if i use a 34 turbo ill need a new dump pipe right? + i dont like to buy second hand parts about 80% of parts ive purchased have been dodgy in some way

as the person above this post said he was fine with it

-shudnt a boost controller stop it spiking? i dont really get what you were saying before about the spring being to tight and frying the clutch

yeh i forgot to add im running a 550hp walbro

The $960 high flow does not includes any actuators. We normally slot the factory actuator bracket 5mms down wards so you can add a little pre-load on it instead of 7psi, Depends on the pre-load that is on it. we normally sit them to around 10psi.

Other customers who bought 1KG, 1.2 KG or high pressure actuators will endup with higher boost readings. after all I would be expecting every one to run abit of boost through them.

Fuel pump, cooler, with high flowed turbo should have no issues running on 10psi with stock ECU. You can tab the CAS very slightly advanced on 98 fuel and get 200rwkws using factory map (do it on a dyno).

btw i was the guy who rang you yesterday, i sent the turbo your way earlier today.

so what your talking about with the wastegate having a preload of 10psi, does that mean 10psi is the minimum i can run ?

also wat do u mean by tab the HACS slightly ?

cheers

We don't have to pre-load it and leave it at 10psi. We can keep you bracket slotted so you can pre-load your self when needed. But once set it will be the lowest boost amount you can run. Also I meant CAS (Crank angle sensor). If you advance that by 2 degrees it using 98 fuel it will give abit more power, But test it on a dyno just in case engine pins.

    • Yeah, it's getting like that, my daughter is coming over on Thursday to help me remove the bonnet so I can install the Carbuilders underbonnet stuff,  I might get her to give me a hand and remove the hardtop, maybe, because on really hot days the detachable hardtop helps the aircon keep the interior cool, the heat just punches straight through to rag top I also don't have enough hair for the "wind in the hair" experience, so there is that....LOL
    • Could be falling edge/rising edge is set wrong. Are you getting sync errors?
    • On BMWs what I do because I'm more confident that I can't instantly crush the pinch welds and do thousands of USD in chassis damage is use a set of rubber jacking pads designed to protect the chassis/plastic adapter and raise a corner of the car, place the aforementioned 2x12 inch wooden planks under a tire, drop the car, then this normally gives me enough clearance to get to the front central jack point. If you don't need it to be a ramp it only needs to be 1-1.5 feet long. On my R33 I do not trust the pinch welds to tolerate any of this so I drive up on the ramps. Before then when I had to get a new floor jack that no longer cleared the front lip I removed it to get enough clearance to put the jack under it. Once you're on the ramps once you simply never let the car down to the ground. It lives on the ramps or on jack stands.
    • Nah. You need 2x taps for anything that you cannot pass the tap all the way through. And even then, there's a point in response to the above which I will come back to. The 2x taps are 1x tapered for starting, and 1x plug tap for working to the bottom of blind holes. That block's port is effectively a blind hole from the perspective of the tap. The tapered tap/tapered thread response. You don't ever leave a female hole tapered. They are supposed to be parallel, hence the wide section of a tapered tap being parallel, the existince of plug taps, etc. The male is tapered so that it will eventually get too fat for the female thread, and yes, there is some risk if the tapped length of the female hole doesn't offer enough threads, that it will not lock up very nicely. But you can always buzz off the extra length on the male thread, and the tape is very good at adding bulk to the joint.
    • Nice....looking forward to that update
