Possible Power Gain

[SKYrine_Dan]

Hey guys,

Im buying a boost controller and goin to run 12psi! Just wondering if anyone would roughly know how much extra rwkw i should probably make?

Lasy dyno run i made 180kW@ wheels on standard boost R33GTST + exhaust + FMIC and pod filter

Any thought appreciated in advance!!

What were the afrs? And whos dyno?

Thats almost too good power for your mods. Either:

1. The dyno was reading high

2. The fuel pump is on its way out and its running lean

3. Its a complete freak

Do make sure you wind the boost up on the dyno as something sounds suss. Wouldn't want it leaning out and going pop. :S

Done @ BOOSTWORX last year! Even Shaun said that was awesome to get that figure and as far as i know thats all the mods that has been done to it! From memory the AFR was around 10,11 or 12 cant quite remember coz i got the printout at my work. The guy who i bought it off of said in the for sale thread that the ecu was chipped in japan but i had a look and could see no evidence of this.

what do u mean "standard boost"?

with exhaust and FMIC the car will no longer running standard boost

and as you said in the other post the ECU is chipped (higher boost?)

When I bought my car the previous owner gave me a dyno sheet. Mods include 5Zigen catback 3 inch zorst, 7 inch muffler, K&N air filter and thats it, and it was running 6/7psi (stock boost) and doing 153kw @ the wheels, dynoed at boostworx.

Now I'm running 14psi off a Garrett GT3076R, Turbosmart boost controller, turbo back 3 inch exhaust with hiflow magnaflow cat and the same K&N filter, no missfiring plugs (iridiums) gapped at 0.7mm. How much more power over the stock figure do you think I'm making? because I tell you now its ULTRA noticable.

[Cubes]

If your still on the stock ecu your doing damn well and may have one of those 95 freak ecu's that tend not to experience R&R.

However...

14psi through a gt3037 usually is up around 230-240rwkw.

Your probably better off pushing boost down for safety sake as 230-240rwkw is beyond the stock injectors when running stock fuel pressure.

[chops]

If it's "ultra noticeable" it would be at least 20-30rwkw more - although with those mods I'd say probably more than that again.

You've probably picked up a heap in the mid range, and that's often what makes a car feel faster.

Who cares though, if you're loving the extra power, then numbers are far less significant.

[Pauly33GTS-t]

true dat! i dont give a f**k!.... unless your a stat whore who cares!... Although a dyno at boostworx would be interesting.

[Pauly33GTS-t]

Will take your word and put it into action Cubes. I'll lower it down to 0.70Bar?

[SKYrine_Dan]

I had a look at the ecu and if it was chipped id have to crack open the ecu to see wouldnt i?

The outside casing of the ecu had pink writing RB25 turbo manual, like what you would see if it was second hand. So if it was chipped im assuming it was replaced with a standard one for compliance. However i dont know what or if anything else has been done to this motor??

Maybe it has been stuffed full of goodies that i wont see until she goes pop!!!

And by the way its only running 7, 8psi when i did the dyno run!!

Paul.....

Winding boost down sucks...

Get it on the dyno for a cheap power run to see if all is ok, you might be able to keep it up there or at least have a good stab at where is safe.

Not a freak Cubes.

You may not remember that my R33 pulled 177RWKW on the SAU dyno day last year & that was WITHOUT an FMIC & just stock boost.....

I must admit the 3-inch exhaust system transformed the top end power of my car (2 stage boost control sucks), something Whiplash has witnessed fromt the passenger seat. Will be interested to see what it pulls when those mods are done to my car

Yes but its not all that common.

What were the other near stock r33's running? I remember around the 150-160rwkw mark. What were your afr's I don't remember?

Others were running those kinds of numbers yes, but none of them had a full turbo back exhaust system (should know I asked them all ). I actually had a power gain from 1 dump pipe to another too (1st one cracked & you could feel the difference with the second 1) as it was a different & much better design.

As far as I know the AFR's were good, but not sure on exact readings.

Biggest problem though is that it couldn't hold that power for long due to the pissy SMIC.

wat looks like an ECU and resides in the boot above the fuel pump cover?

[EnricoPalazzo]

Thats your HICAS computer mate.

Also I highly advise against running 14psi on your car until you get a decent FMIC mate, as ive told u, the standard intercooler is good for nothing. You will experience detontation, and may not hear it, good buy motor.

Also as you are still running stock injectors, and pump, once again, you are really risking things.

So get it on the dyno for a power run, make sure afrs are safe and no detonation.

Call me if u want any help with anythin.

speaking of weird dyno results... i had my safc2 tuned on my r33 gtst s2, it had fmic turbo back exh, 12psi boost (bleed valve) and that was about it as for power gaining.. oh and pod filter lol

214.9rwkw, dynod @ chasers in melb.. they sort of spun out aswell but i dunno... weird and everyone's said wtf to it aswell.. felt quicker but i've never driven a car over 200kw so i can't compare...

[EnricoPalazzo]

numbers are numbers. More interest is what gain you had from last time, or mph on dragstrip

Thanks Dean man, yer I got it runnin at 0.70 Bar now (lowest it will go???)... I'll organise a dyno run this week sometime or early next week, I should get my FMIC next week too.

[Cubes]

Who did u end up getting the fmic from?

JJ, GKTech etc?
