First up Unique Autosports is cool. :P

Took the car to them today to do a dyno run, and encountered some problems (weird curve) and not much power gain. Anyway, out came the console (sp?) and timing gun, which revealed that the base timing was retarded,...so they advanced it. The car was then run up again, and there was a significant increase in the power throughout the rev range. Whoo! Cheers UAS!!

The last time the car was run on the UAS dyno it managed 166.9rwkw @10psi. Today it made 184.2rwkw @ 11psi with the new hybrid FMIC. (The red lines are from the last run, blue's new.)

I can definently feel it in the seat of the pants dyno too! Put it this way, I just got home 30mins ago from a quick drive and I'm still smiling.

There's some weird stuff going on high in the rev range still. A power FC will fix all that up, and should net me...ummm...lets hope for 200+rwkw. :)

(dyno sheets attached AFR, and PSI)

Wilch - well done mate :P

Nice results.

UAS have a really great team and facilities :)

I was gonna come down to UAS today, but had to get a new turbo water hose

Once again - good effort and well done to UAS.

Go Adam and Ben :)

There's no torque line there at all dude.

The first graph shows AFR's, the second graph shows PSI. Have a look again.

The blue lines are the new ones (w/ intercooler), the red lines are the old ones (from the run without the intercooler).

Wil - have you got SAFC or anything ? Or are you just using standard ECU ??

 

PFC will make a big difference :P

Heya B-man,

Nup no SAFC. Just the stock ECU, full exhaust (except w/ stock cat), pod in cold air box w/ cold air feed, and the profec b2.

I will eventually get a PFC. I just need to wait for next months pay packet. So within 2 months and I'll be cheering even more so :)

I had my car dyno at unigroup. I got pretty much the same results as yours but i got a bigger dip at top.

Had Hybrid front mount running 12psi with avcr, exhaust and pod filter

Dam thats a huge Dip, u gotta feel that lol

1 thing i dont understand why my line is a curve when i dont even have a boost controller, just running a cheap Bleed Valve. Would expect the boost controller to atleast not have any Dips in it.

The dips in my power line are due to the stock ECU going, "Hmmm, there's a lot more air than normal, oh s#!t, time to retard the timing...wait...things are ok, advance the timing...oh s#!t, retard again....etc etc etc"

I'm guessing you're either running an after market computer, or piggy backs. You'd never make 249rwkw with the stock computer, nor would the power line be a nice curve. I'm assuming your turbo is high flowed too, or you have some schmick bigger turbo in there.

hehehe...cause if you don't, i wanna run my car on the dyno you ran yours on! LOL :P

Hard to tell....... Do a dyno run where they chart your psi.

I know of another that runs a bleed valve, and the boost runs up smoothly, then falls off significantly higher in the rev range (ie. doesn't peak, and hold... the ebc's tend to peak and hold if set properly, or like mine, spike right at the start then hold. LOL).

      S1 headlights?

      By Duncan · Posted

      It might be worth having a good look at the chassis behind the bumper then; most people prefer the series 2 look so it might have been changed to cheaper parts as part of an earlier repair

      By Celticsfan03 · Posted

      The car itself a series 2. I was just curious about the headlights and just wanted to confirm that they were series 1. Good to know the rest of the front end is series 1. It’ll be easier for me to find parts on the aftermarket side of things lol

      R34 engine swap Rb25de neo to s1 Rb25det

      By WMDC35 · Posted

      If you've wired up the coils & injectors properly, & have the neo CAS loom for the trigger, it should all work. The VCT works the same way so just different plugs between s1 & neo. Assuming DBW if no IAC. Don't bother with the stock boost solenoid with g4x.

      THERE IS NO IAT SENSOR ON ANY SINGLE TURBO RB. And the one on an RB26 is not for "engine control" - it's really too big and too slow and is only used for over-temp alarming (as far as I can tell). Anyway, you don't have one. You want/need one for the Link, then you need to buy one, find a spot for it, and wire it in. You do know that the stock boost solenoid is not capable of "control", right? It is merely on or off, for the low boost (5 psi) and high boost (7psi), which the ECU enforces mostly based on gear. The stock solenoid is not for PWM control and is not plumbed up in a way to provide it. If you want to control boost properly, then you need a proper MAC valve. And yes, you can wire either of them direct to the ECU. Well, I assume you can - I don't know what the boost solenoid pins on the plug and play Link are capable of. They really should be as capable as any normal Link - but seeing as it is plg and play, it might be limited to stock functionality. Read the doco.   You really do just want to plug stuff together without understanding how it works, right? I can't help you there. I don't know the plug types or pinning on half the stuff you're asking about. If I had to do it I would sit down with the wiring diagrams, the car/looms and a multimeter and work out what is what.
