There is usually an occurrence of minor boost creep with colder temperature. Ie 14psi at 30 degrees and 16psi at 10 degrees, I haven't see it going backwards. Perhaps tune or ignition related?

Look at the torque difference at 3k between your SS2 and the latest one.

You'd expect the Neo engine to produce a little more response anyway...I'd think? That latest run is an S2 R33.

That car had a bell mouth dump with a hi-flow cat. On the standard manifold, I was impressed.

The car equipped with the older version SS2 had a ebay exhaust manifold on it during the time. So that difference contributes to the larger exhaust manifold. The differences between those two turbos are minor, how ever the new SS2 has better ability in boost control for internally gated setups.

Definitely a good result, its a good bolton turbo.

I'm pretty sure the new SS1PU will follow the same league, that will be amazing.

Oh ok, lol fail.

There are 2 areas I am dubious of. One being a hose that is a PITA to get to which had cracked previously and I cut down. The other being the EGR port at the back of the IM. I made my own little block off plate for it but I have since sealed the actual EGR valve which I can put back on with an OEM gasket. That will likely be better than a silly piece of alloy.

I'll see if these are an issue :)

I had some issues with cuts and Nistune on the Stagea with load cut. I am not sure how why it can hit the set value while driving but not on the dyno but I lifted the values to the max as any cuts while driving on the road are a little risky.

Do you have the Nistune software to check where Yavuz set the load cut?

That I do not! And the car is unreg so I can't easily take it back to him to have a gander :(

Jez is also miles away so am stuck with very little help. I may need to lash out on some software.

Awesome result Scott. A 13 flat Is nothing to sneeze at on street tires.:) can't wait to see the times you pull when on a full tune. What are you hoping for?

Cheers!

Re ECU LOL Nah, can't.


I have spent just shy of $3,000 on the Nistune and tuning to get to this point.... Admittedly only half of which relates to the current tune and motor (last setup was a failure), but it is still a mega investment I would feel stupid to give up on.. Resale on the nistune would be next to nothing. I just need to go bark at the tuner about the couple of issues I have with the tune and get it fixed. I believe they relate to the weather on the day of the actual tune, limits were just set too low and a flat spot pre 3k rpm probably couldn't be felt on the dyno.

Am gonna think about investing a little more into better boost control and will simply get the tune tidied up.

Am expecting the final result to fall close to the 260rwkw mark and I think I will snatch a low 12 :) That will be enough for a car that doesn't cause a scene when it comes out to play. Simple car, simply good results.

Its best letting the tuner keep and drive the car for few days which allows him time to explore any minor imperfections. If he believes the ECU is fine and the car is welling behaved well within its command then there isn't much of a point replacing it.

If not invest into an adaptronic plugin ecu. They worth that 3G lose.

Got my 20psi actuator today off stao

Awesome service just ordered yesterday

Looks heavy duty the rod is a lot thicker where the std one is a 10mm locking nut this looks to be a 12 or 13mm

Can't wait to fit it and try to get it to hold 24psi flat and then ill take it to the wsid fingers crossed 11s

It drives so much better than before touch the throttle on 18psi powers there instantly if your cruising a 3krpm it's scary fast if there's no wheel spin where before I had nothing till 4krpm

Sounds awesome man. Glad you like it.

is yours an SS1PU like mine or a G2? Whats the actual spec, stao please confirm?

also Urs is VCT or S13 spec motor?

Here's a dyno sheet of a s14 with the same turbo but no fnt and not e85 it's not perfect comparison but same dyno

the fnt has shifted the powerband towards the left

Mine makes 20psi by 3600rpm his makes it by 4400rpm

S14 make 90kw a 4000rpm mine is making just over 200kw

The FNT makes a big difference for sure.

Mine saw 20psi at 4000, but I'm curious to see what it will do when I go back on a cooler day. I've got the S14 motor but its not running VCT. Just S13 spec Poncams and gears. Tuner didn't touch the gears though :(

Admittedly, the powerband is awesome at the moment... I don't need it any stronger and the torque I get at 4k is nonsense. Once I sort my tune I will have to organise a drag night with you. Not gonna go back till I fix this boost/load cut issue. Got to decide what to do about boost control first but.

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
