My "mild state of tune" opinions please.

[JAP63]

i want opinions on how feasible and reliable this set up would be,as this is what i am soon aiming to have.
Highlight me any shortfalls or dangers etc...
and what power u rekon its worth.

MOTOR MODIFICATION
-K&N pod and custom 3 inch inlet pipe.
-16 G E3 Turbo on standard vr4 manifold
-2.5 Inch dump and rest of exhaust in 3 inch (wastegate merged in at 300mm and a "very highflow cat")
-Evo zero cooler
-Evo zero cooler piping.(bigger-57mm I.D)
-Custom 60mm inlet pipe (to plenum) and throttle body elbow.
-Stainless 60mm cooler pipe off compressor outlet across manifold
-550' injectors
-Stock computer and AFM with an SAFC2 piggybacked on.
-K&N pod and custom 3 inch inlet pipe.
-A bigger fuel pump..(walbro 255??)
-Boost manually set at 12 to 13 pound.
-Then a dyno tune.....for hopefully around 160-180Kw @ all 4

So thats it..basically an Evo zero with better induction piping and the exhaust plus a few fuel modifications.

What everyone rekon about the tuneability of the SAFC2 for the given modifications? and the power i think it will make.?
Im not keen on doing any more or really goin to an aftermarket computer.

Don't be offended Jamie but if you plan to have the boost set at 12-13 psi you would be better off leaving the 14b in there.

With the 550's and better cooler/exhaust setup i'd be running that puppy closer to 20psi

-K&N pod and custom 3 inch inlet pipe.
-Stock computer and AFM

STD VR4's mani's turbo hole is smaller then the turbo inlet, i believe you can port it out, but VR4's mani's are **** :evil: (my s16g is on a std VR4 mani - hole is to small for it, so losing performance :cry: ENTARAN :roll: )

Also better off with a 2G AFM (don't cost much) straight intanke pipe and CAI

What about if i got a standard evo manifold?

Thats a good point,
but what about the E 0's that come out with a 16G though only on 10 pound?

I would never be able to run 18-20 pound with an SAFC2 piggybacked onto Stock AFM an Computer though.

would the car be slower than a 14B equiped car?

Why not :shock: Better not tell me it carnt be done :roll: (AFM is a 2g unit)

 

[brisvr4]

Jamie, if you get a set of Evo 560 injectors I have a chip here that you can have for it.
It will get you a LOT closer to a good tune than with the SAFC alone.

At 18-20psi on the stock comp you will be hitting fuel-cut all over the place too!

Hmmm, not too sure about the E0's Troy??

I Have a chip+SAFC+550's+std FuelPump - no cuts anywhere

 

[matress]

i'd expect around 150-160 with that amount of boost...

you really need a chip to remove the boost cut so u can wind some more boost into it.

bigger air flow meter might be a good idea too

why not?
i ran 25psi through a stock computer

 

[Skuz]

u running the standard zorst mani? alot of people are getting good results out of the gtpumps mani. also go for the bigger AFM. dont cost alot these days.

[GVR40]

sorry to go off topic but is the 609 afm or the 055 afm better, tim i will pm you about that chip

 

[tharaka]

they are the same

 

[VR-4Squid]

Use the evo manifold - the metal is slightly different so their not as prone to cracking as vr4 ones.

walbro pump is a good idea.

chipped ecu > safc

Evo afm is a must.

I'd not bother with the evo0 piping and go full 2.5" with the cooler inlet/outlet enlarged to suit.

no reason you can't run 18-20psi on that.

 

[rob323]

I can vouch that 12-13 psi on an e3 turbo is slower than with the 14b turbo, but bump that even up to 15psi and there is a noticable change in power.

 

[brisvr4]

sorry to go off topic but is the 609 afm or the 055 afm better, tim i will pm you about that chip

I'll let you know which flows better once I have tried them both out Craig.
Should be done by the weekend

I can vouch for the 14B turbo.... 16psi with 14B came onto boost much quicker than my big 16G. However, the VR4 manis arent much good. Mine cracked and changed the whole turbo setup for an EVO2 item..... If I did it all again, EVO mani and 14B turbo. This would make an ideal setup for a person not chasing big power figures....

With a 16G you can run some boost that can potential damage your engine after time. But with the 14B you cant run much more 16 or 17 pounds efficiently.....With the 14B the temptation isnt there to wind up the wick so to speak.

Bottom line, if your 14B is in good shape, stay with it.

I like your train of thought..

So you rekon i should get an E2 manifold ?
It would be a good step up?

why not?
i ran 25psi through a stock computer

Ok so im not a genius on this stuff (tim is) but il have a go an explain why i cant do it.
Firstly..

I have the stock computer...no chips.
The stock computer has a boost cut,it sees a pre determined volume of air and says "no",too much..and gives a cut.

What i did was go from 450cc to 550 cc
13% bigger
In order to be in accordance with the difference,i would now set my SAFC2 to -13% on the maps and it will run the 550's as it would the same amount as 450's.In essence my 550's would act just like stock 450's on a stock car.
So if i then go to my maps and change them to -5% i am actually on +8%
Im actually getting +8% fuel but the computer sees an air figure of negative 5..because it sees less air it cuts later.It thinks it hasnt reached that predetermined value yet.

The more fuel i wind into it,the more air it sees,or thinks it sees (as im telling it) and of course it will think its getting too much air..then cuts.So if i run higher boost,of course i need more fuel,so i wind up the fuel,as i do so i make it cut...remember it htinks its still running 450's and the only reason im not pinging is because im actually firing 550's


The problem with the SAFC2 is..if you go huge on injectors and low on maps to try and confuse it even more and get the boost cut to come in even later,yeah it will work,but what it will also do is give heaps of timing,youre telling it.."no air",i guess it wonders why at 5K theres f*ck all air being pumped through the motor,so it bumps the timing up..when in fact you have 18-20 pound of air there,and the last thing you want is a hit of forward timing...the quickest way to detonate the motor to bits...

In fact i suspect the thing would spend most of its time talking to the knock sensor and pulling the timing all over the place like a mad dogs ****....and of course run like shift.


Howd i do Tim?

 

[brisvr4]

You did pretty well there Jamie

With the 550's you should be able to pop in a 055 maf and not have to adjust the safc at all!!

I'm pulling my 055 off tomorrow, you can try it out if you like.

Come up to Craigs on the 4th of Feb and we can log it too.
