I’m just running walbro 450lph in tank n that’s it! I’m rhd so am needing to modify the outlets for more boost!

I’ve noticed he’s brought boost in slower in third now so it doesn’t keep knocking the tires off which is more controllable n 4th is back at 20psi!

Thanks for having a look, sometimes you miss stuff and always good to have a second opinion!

👍 You want boost to be dialed in progressively, otherwise too much torque low down will cause traction issues and you'll just blow the tires off, fun though it is,.

Look like a solid set of turbos, I'll probably be getting RB OEM Billets or 1's, when mine go.

They pull really well for how old they are n the constant abuse they take, no wastegate rattle either!
Will be heading to the dyno soon! Am hoping for around 500crank hp! My friend had the exact same setup n his dynod at almost 550hp at 19psi!

have been trying to grasp what is going on and understanding alot more now to the point where i help others,
would just like someone to have alook incase im missing something!
car is fbo and uk pump fuel + octane booster, rb turbos!

thanks all

Are these RB ones? The boost up top and wgdc are what i had in mind for my next set. Side note, your iats are going up.

Yeah rob beck turbos stage 2s at the time of manufacture 2014,
Iats are climbing as you can see, I have the Wagner 5”stepped intercooler, my tuner said I should start running meth to keep the iats down and spoke to rob about turning up the boost which he said to leave at 20psi till I modify the outlets!

Emailed Rob, these are closer to the RB Twos from his current line up and superior to the Ones. Good boost and wgdc.

Or you could get a good 7 inch FMIC,

Yeah mate they have been spot on to be honest! I mean I’m not pushing crazy boost through them just 20psi but that has been a hard 20psi for a very long time lol

I’ll probably get a vrsf 7” one in the future! I might also try n see if I can get somemore cold air into my afe air box!

Finally got some cooler weather (80F) and got a nice 3rd gear pull. Chasing intermittent timing corrections on random cylinders no matter the tune, so I'm banking on 50k mile coils being a little bit tired. Flex fuel stuff going in next week. Is LPFP fluctuation under full load like this normal? Is it still adapting to the 535 (less than a week installed)? Also getting some throttle closures. Thanks

LPFP looks fine, above 60psi+

I'd keep an eye on the HPFP, it goes down to about 1600psi initially and then picks up.

Since Cylinder 5 is the only one with timing correction, you could swap cylinder 5 coil with another coil from a different cylinder and log again to see if the correction follows.

Corrections could be due to coils/plugs, fuel octane level and even injectors.

Would start with cheapest to try eliminate or reduce them to minimum

Hey all,

Would someone be as kind as to have a quick look over these two for me? Both 3rd gear dsc off pulls. I only know to look for timings, which look good here, but is there anything that looks out of place?

IAT`s are high as I had the car sitting running in the heat for a long while before setting off to do this run.

You went WOT from about 1400rpm, would recommend you never do that mate, that's asking for trouble on a boosted engine.

Can you do another log, this time from 2500rpm with DSC fully off till over 6k let the transmission shift them back off after a few secs.

Yeah will try to!

Didn`t know just planting the foot and letting the car build could cause issues

No worries mate,

Yeah, at low rpm high load (WOT) puts excessive stress on the internals of the engine, can cause serious damage.

[Chapperss]

Hopefully got it this time

First link I shift to 4th and then let off the gas pretty much straight away

https://datazap.me/u/chapperss/log-1...og=0&data=3-21

and this second one I carry on going in 4th and shift (early) to 5th and then let off the gas.

https://datazap.me/u/chapperss/log-1...og=1&data=3-21

Input on what i`m seeing here and what it means greatly appreciated

HPFP fine, IAT's fine, boost is slightly off target, judging from WGDC doesn't look like you have a boost leak, Timing corrections are minimal and mostly post shift, which is normal. LPFP drops below 50psi to 49 initially but picks up soon., this is most likely because of the throttle closure so it's fine.

You tried V9 maps?

That all sounds very positive, which is good and what I wanted to hear. ty

Will do some research on the boost being off target, seeing as you say it`s slightly I won`t go mental on it though. Very happy with the way the car drives atm.

I tried V9 last year when I first got the car and found the power delivery not to my liking, V7 gelled much better with my style of driving. May give it another go now I`ve had the car a lot longer. Any particular reason you asked?

I found similar issue with boost off target with v7 but v9 was almost completely on target. Its not a major issue, yeah I agree v7 feels more aggressive according to the butt dyno lol.

Hi does this log look ok?

[cmcgonag]

Hey everyone,

I have a 1M, and I cant get the stupid thing over 11psi and was wondering if you could help out. Below are the Logs for Stock, Stage 1 and Stage 1+.

I cant tell if I have a boost leak somewhere or what. Curious yalls take. My timing looks horrendous on stock low rpm (dont know if that is just a bumpy road).

Car has FMIC, turbo inlets and outlets, and MHD. The N54 1M cats are also a little better than the normal ones FYI. (Ambient was 90F)

Any help would be greatly appreciated.

Had a look at the stage 1 v9 map, wgdc reaching 70% and off boost target throughout the pull indicates most likely a boost leak.

Also the I'd stick to v9 maps, stage 1+ was v8 map and it looks worse than the stage 1v9 map, probably made worse by your boost leak, but v9 should run better.

You may not have a 30FF code but still a good idea to follow the advice here to rule out boost leaks.

Smoke testing is also a good idea.
