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).

      Definitely do-able haha. I will give it a try if the fuel pump hanger does not solve the issue. Just need to find some quiet time in the area, Malta is like a big city and I live right next to the main hospital so it is very busy during the day. I'll be installing it in about 2 weeks, found a garage that is pretty knowledgeable and has the necessary tools. This garage has worked on multiple builds, even for competitions. They even asked me to stay with, so I should be fine.

      Just to add, I found the r32 gtr ecu the most forgiving, the r33 one would get the shits.

      For what it’s worth I drove my gtr for over a decade with gt-ss as a true daily after I pulled off the -5s, I had it engineered and went with stock ecu etc.  never skipped a beat.    I would only worry if you can’t get good fuel all the time in a tropical paradise

      Engine model

      By Bwagz · Posted

      I bought an engine from a friend of a friend many years ago, it was sold to me as a RB25det Neo.    recently I started pulling it apart and noticed that the intake manifold was pretty different from others that I had seen on RB engines so did a bit of research and found that it was a non turbo manifold. So I’m sceptical now that it is a NEO DET and just thinking it’s a NEO DE (it does have a turbo strapped to it currently).    can you identify the engine model from the numbers on the block?

      Yeah you can. Cable tie the gauge to a windscreen wiper, or run it into the car and hold it with one hand, or have the neighbour's kid run alongside and tell you what it says.
