So does anyone make an alloy one with bov/breather return that isn't $300 ?

[Trozzle]

hahahaha my suggestion was in no way serious I'd hate to think what kind of distorted readings the AFM would get when placed directly in front of the turbo inlet anyway.

Does anyone make an alloy one with bov/breather return that is good? I didnt know there were any at all, at any cost.

[SimonR32]

I just made one up myself... Just get a 3" 90 deg bend and weld on a few plugs then use radiator hose to connect between original return pipe and the custom intake

[Harey]

Yup I am gathering parts at the moment to do just this.

Thats exactly what i did. $10 scrap exhaust bend from an exahust shop. cut the bov return and oil breather metal return pipes off (about 30mm cut off) turned them around and welded them onto the exhaust bend, then 2 small hoses (about 80mm) long to join up the now cut bov return and oil breather.

Chasers made mine because, as other people have found, the rev210 mod does have it's limits. 2 x 45 degree bends were used in the end i think, they wanted it as straight as possible.

They did say it was tricky to get it to work, which must be what all of you guys are talking about.

I have the standard airbox and standard BOV, plum-backed.

Wasn't cheap, $300+, but still let me run everything as it was and in it's most standard configuration, whilst being the straightest possible pipe.

that should all be past tense, as i no longer have the car

Thats the next level of complexity again as you have to connect it up to the standard airbox. I am just talking about a pod filter so it doesnt have to be as precise.

I made THIS for the same reasons as above.

All you need is some alloy pipes and a welder.

I made this one 2.5" on the turbo end and 3" on the AFM end so no need for silicone reducers (ugly)

Good to see another way of doing it!

However, for the guys with larger turbos I am sure it would be beneficial to go straight to 3" as quickly as possible from the turbo. I know its the not exactly the same but its sort of like a bellmouth if it goes straight to the largest diameter. Thats my theory anyway.

Had car retuned today after I had a few issues fixed up...I'll be providing Stao with the dyno sheet to post up first once I pick the car up, but all I can say is that I'm very happy with the figure. Considering I asked the tuner to be as conservative as he could and very safe up top, it still made stupid power. He was skeptical of the turbo since he'd never heard of them before, but was pleasantly surprised (or astounded moreso) with the power it made.

Since it was running without any boost control, boost came up to ~17psi initially and bled down to ~15.9psi. Tuner took out as much timing up top as he could before it would begin having a negative affect, and it finished up with 11.5AFR. Not sure of the rpm yet, but at 15.9psi it made 294rwkw.

Safe to say I'm stoked with this result.

[Randon_I_Am]

Thats awesome, can't wait to see the dyno graph.

Mine's going back on the dyno on monday too! last tank of fuel before i switch to E85

You're a prick. I want some ethanol action

Who's tuning it for Ethanol?

Sounds good! Keen to see your boost graph so don't forget to get a print out while you are there

Also try and get the runs printed in rpm if you can

[Randon_I_Am]

Not sure mate. I'll go back to Ed on monday to get a "before" and base tune.

Then I'll tune the AFR's myself and up the timing a bit. Then bepending on how Ed goes with the before tune i might go back to him.

Otherwise i dunno

[Trozzle]

Fair enough

[hypergear]

As some already seen the ceramic ball bearing high flow results. This is based on a stock Rb25det with factory head, cams and cam gears with forged bottom. Turbo did have some unexpected boost creep issues due to a newer designed waste gating system.

Tuning video footage of 4x consecutive runs. with consistent 321rwkws:

Turbo has been pulled apart, we are analyzing its bearing components and modifying its turbine wheel refer to some skeptics for faster torque gain.

Also we will be testing some cage less air craft ceramic bearings for even faster spool time.

Also for people whom's interested in sleeving stock rubber pipe with metal and hopping for great HP. Below is a dyno comparison to show you it doesn't work. and please don't waste time trying. (The drop at 6500RPMs was from operator back off per discussion earlier)

I would highly recommend going fora 4inch metal intake pipe with pod. All ATR43G3/4 units will be now built with a .70 comp housing with a 4inch inlet unless special request.

[Trozzle]

Since I got no idea if Stao is gonna chuck these up or not, here's the dyno charts from my tune this arvo. I don't get a torque chart tho

One shows power+boost, one shows power+AFR. They've been overlayed onto the graph from my first tune when I was having boost issues. The RED line is from today (though I dare say that will be obvious lol)

Big thanks again to Stao and his great work, another happy customer here

[hypergear]

Thanks for uploading. I was about to re-size them first. Unfortunately above turbo had some shipping damaged to the actuator lever which caused it not been able to shut in the earlier run. Great to see thing's back in working order. Hopping to see more power at 20psi

[kwickr33]

Looks like your tuner's trying to stop it from going over 300rwkws. Never less good result
