Sliding Performance Highflow For Rb25det

[Slide]

Now you just need the auto box built up to handle the power and head to the drags Joe

Great to see all the results popping up out of the woodwork.

im sure the auto will be up to it. have faith brother!

the map isnt closed loop, your fuel map is determined by the amount of air passing though your AFM.

your larger turbine will come in later and suck more air later, so until it comes on boost, the ECU will add the correct amount amount of fuel for manifold vacuum.

when it does come on boost, it will see more air going through the AFM and compensate with more fuel

i've got an safc2 which was tuned. from my knowledge about them they correct fuel at SET rpm points, not 'when the turbo kicks in'. someone correct me if im wrong.

You're not wrong

do you plan to turn the car off after a few hot runs to see if the bearings fail?

thats a serious question

Why would you want to do that? Seems stupid to me...

One of the important things about journal-bearing turbos is that oil flow must be maintained. Why would you want to risk farking the turbo by shutting the engine off when the turbo is red hot, just to see if it fails or not? Maybe it won't fail, but you may have caused minor damage which later compounds and causes a bearing to let go???

[Slide]

I would not encourage hot shutdown's, Even with ball bearing turbo's damage can be caused.

It is now common knowledge that doing hot shutdown's not only can damage your turbocharger but damage your engine.

The topic has been covered many times before and logic always prevails.

GTR's have nearly all journal bearing turbo's from factory and very rarely fail unless overboosted.

The failure is because they have ceramic turbines not because they are journal bearing.

Silvia's Journal bearing from factory.

Toyota Supras, Surf's, Celicas.... Journal bearing.

In some cases these are still all going after 100.000km.

So saying that journal bearing turbo's previously have shorter life spans then ball bearing is a little hillarious.

These at the end of the day have been driven like normal cars for many years and nothing has happened in most cases.

There are always a very few amount of people that like to start the debate up every time with the same outcome.

Sometimes hot shutdowns are unavoidable and i have had it occur many times due to something as little as an atmospheric blow off valve making the car stall.

I have pulled apart many turbo's after this instance and bearings have been fine.

There is this huge halo around ball bering turbo's and thoughts that they dont fail.

This is not true and i have had pallot loads of ball bearing turbo's taken away as they do not have the versatility that journal bearing turbo's do and ease of repair.

[SECURITY]

yeah you know what, that makes sence. why risk farking my turbo? if it fails in the line of duty then so be it, but if it fails from me running it in a way where i wouldnt usually, then whats the point?

[Husky33]

exactly.

There are just some haters out there that can't hack people buying $800 hiflows that are comparable to $1600 hiflows.

I won't raise the argument again, but just leave each to their own. I know what i'd rather spend the extra money on

[SECURITY]

i thought an update was needed after so damn long.

the turbo is going strong. VERY strong. im running it on 14psi daily. might hit 18psi a bit later but i havent been bothered opening up my bonnet for a few weeks after all the time ive spent under it lately!

i've sold my SAFC and was getting around 380/tank with the tune i had. on the standard computer im getting 430km/tank which im finding strange.

anyways, the reason for the long reply was i had a few oil problems. i did my valve stem seals, fixed up the pcv and its all running sweet.

also because of the n1 oil pump im using which pumps 25% more oil ive been told, ive made the reducer 4mm as to not flood the turbo.

im going for the greddy ultimate so ill be back with results after im finished with all of my uni work and exams are over (i know ill spend too much time on the car if i get it before!).

[Trav33]

What sort of power are you getting out of your beast?

I had my powerfc installed after running my sliding performance high flow on the stock ECU for about a year. It's now putting out 190rwkw on stock boost (7psi), but i cant boost any more at the moment, cause my clutch is slipping!

Time for a new clutch, and then aiming for 230-240kw on slides awesome turbo!

[SECURITY]

i havent dyno'd it yet mate. ill post results once i have.

[PM-R33]

Hey mate, just wondering how its all coming along?

I'll be getting my highflow in a couple of weeks off of slide and this thread is a great read

Cheers mate

Interested to see what piggy back your gona put into that car, since its an auto

its going well. comes on boost nice and hard, even with the standard computer.

i can use a pfc if i wanted to champ. dont believe everything you read

but i've decided to go with the emanage ultimate (also off slide). its got everything i need + more. i'd probably even go for it if i had a manual.

Hmm i think the emanage provide fuel control and ignitition, but i have read somewhere that the ignigtion control 'retard' is handled by the ecu for shifting.. So i think that you would only benefit from the fuel control.. lol dont qoute me on this but im sure i read it sumhere

it is true that the ignition retard is influenced by the auto ecu, but because you have control of ignition through the emanage you can turn that timing back to where its supposed to be at any particular rpm.

[ICER33]

this is very interesting because its nearly exactly the same setup as i am going to run..except for the e management (going pfc) and a avcr.

so i am keen to see the results as i am deciding which high flow to go with - the journal like this or the ball bearing., i am not sure that the dramatic increase in price is justified given the comparision of the results.

get it up and keep it posted mate

[adzR34]

Joe, that sounds like a plan then, if the emanage goes well for ya be sure to tell us about it,

lol thinking of throwing one on my auto GTT

[SECURITY]

im trying to get my car ready for the track so i dont think ill be getting an emanage just yet. after the track day ill be saving up for it + a tune. i'll also be getting the sensor so i dont need to run an AFM.

ill MAY be hitting the dyno before the track day to see where my AFRs are at so ill keep you all posted.
