Kw Bingo - Guess The Power Output

[exitSTAGEAright]

Ok, so my stag is FINALLY going on the dyno tomorrow for a tune. What's the guess of RwKW (getting done at UAS in Sydney who only have a 2WD dyno) ??

1997 RS Four V

Mods are:

BOS 3" split dump pipe

Catco Metal Cat

Trust Power Extreme 2 cat back zorst

K&N Panel filter

R34 Intercooler

GTR Fuel Pump

AFC Neo computer

SITC computer

Turbotech mechanical boost controller (expect set to 10psi)

Full service has been done with new filters for everthing, spark plugs, timing belt and water pump so running sweet as a nut.

The prize will be bragging rights for knowing your stagea power figures

I'm going to go for 190.4rwkw

At a guess, hmmm hope I get close GO THE STAG

[Tangles]

at 10psi you should see around 150rwkw, give or take 5rwk. say 155rwkw as my "jellybeansinthejar" guestimate

same sort of stuff, at 12psi, I was seeing 160awkw.

doesn't attessa play funny buggers on a 2wd dyno?? I thought it went haywire unless a 4wdyno was used...

[Stinky Rooster]

you can just undo 4 bolts and drop the front driveshaft, but you will lose about 10kw.

[stasis]

you running on 2wd or 4wd?

hmm roughly about 140-150kw, i should say it also depends how many kms has the engine done?

[exitSTAGEAright]

I am running 4wd, but Unique Auto Sports only have a 2wd Dyno so they will drop the driveshaft out. I am hoping for 150awkw, so would have to be 160 or so rwkw I guess.

Will be a big improvment over how it is now though, which is the main thing

[GoldZilla]

What time are you going there, Stu? I live just around the corner from UAS and have also just booked my car in for some work there (for early next week), so I might come along, meet you and see how your car runs...

[rb26stagea]

you can just undo 4 bolts and drop the front driveshaft, but you will lose about 10kw.

ok.... That being the case, I'll put my guess in at 164rwkw.

[rb26stagea]

sorry. Stupid laptop - posted twice. My bad.

Carry on

Less power transferred, is less power lost.

You will not loose power going to RWD, you would expect to gain a minor minor amount, being its not fulltime 4WD.

11-12psi you will get 190rwkw with that gear and a standard turbo.

thats more like it!

i thought all the other guestimates were fairly conservative..?

[wolverine]

i think the SITC will make it hard to crack 200rwkw with less load points but who knows maybe we can go around and drop the temp probe in to a nice hot cuppa and crack 220rwkw.

EGA4IT made just over 200rwkw with an RS4S and powerfc with similar mods on the same dyno as a comparison.

[jasevr4]

Does the Neo6 make much difference once you start modifying it?

[wolverine]

quite possibly/probably the neo stageas have an exhaust cam with only 7mm lift (vs 8.4mm in the GT-t) if so this will limit the power unless changed. other than that not much difference.

[MyStag260]

Hi exitstagearight, i will have a guess at your jelly beans.... hhmmmm lets say 203rwkw

Good luck

Cheers

OK, the results are in and the winner is .....

Max power 152.9Kw at the rears running just under 10psi. This is a Series 1, not neo motor by the way. And an auto

I will scan the printout at some stage but Andrew at UAS did a nice job on the tune. Power deliver is smooth all the way through with no dips and boost holds constant the whole way. Go the $30 Turbotech controller A/Fs are around 12 or just under too so nice and safe.

They did not tune the SITC this time as worried about detonation with the side-mount intercooler and I am driving to Brisbane this weekend so I think they are playing it safe. With a FMIC, exhaust cam gear and some more tweaking on the afc and sitc I would hope to see another 20Kw. All in all pretty close to what I was expecting so can't complain about that.

Goldzilla ... sorry I missed your post as my PC at home is dead and I went down there first thing this morning. Is yours the green one coming in for a 'trial fitting' next week ??

Speaking of fitting, the Power Extreme cat back zorst needed a fair bit of manipulation to line up unfortunately. I guess that is the price of mixing and matching local dump pipe and cat with jap exhaust. A word or warning for others I guess, the BOS dump and Catco cat may not line up exactly like factory

[jasevr4]

Wow. That's not much power!? Must be a very conservative tune..
