so the idea of the holes is

to allow some air to bypass the compressor inlet/snout and enter directly into the compressor housing ?

As you can see from the picture of my turbo below, the holes (some turbos have slots) allow the air to enter further out on the compressor blades. This is an attempt to avoid the compressor surge problem that occurs when you have a large turbo on an engine that won't take the airflow at mid to low rpm's.

:) Cheers :P

without

i think it comes on about 3300 with nos and full at 4300 or so

when i get the ecu back

ill post two dyno sheets

one without nos and one with to compare

i have just finished reading this thread, and oh my, how fun it was... everyone seems to be in the same rb25 frame of mind, where it can only push 300 odd rwkws max.. kudos to you mate, your doing exactly what id be doing if i had a dyno on hand 24/7.... see you at the track.

Was the motor that you just blew up stock?

Just got my 2 speed box ordered

and stall converter

should be in next week

will post new dyno graph

and be going to the track to see how much quicker it will go

Video clips havent been uploaded but will be soon when i got time

Hello

I am new to this forum site.I would like to know what is the highest HP at the Rear Wheels produced by an Rb25 motor.

I currently have a GTST skyline and with the standard Rb25 motor and pumping out 498 Hp on 18 PSI.It is a manual skyline.I am running a Standard Motor,GT3540 turbo,Custom plenium,750cc Injectors,Hydra Computer,125 mm thick cooler with HKS style end tanks,3 " intercooler pipes, 3 "exhaust,Aftermarket coil packs.The engine has been run on the dyno about 150 times checking things and testing as i am trying to prove what the standard rb25 motor is capable of.

I am wanting to see who has made more hp.A dyno sheet is available and the dyno is on my own Dyno Dynamics Dyno running shootout mode.Intake Temps on the dyno sheet are 34 degrees and the room temp is 30 degrees.

Thanks

PS this is on Opitimax fuel.

I remember a customer of MazFix's did a comparison on shootout modes on the Dyno Dynamics dynos and it ads 25% more power over normal mode which would equal 373.5 hp on normal mode.

Interesting

but if you read off the dyno dynamics site

it states that it locks all variables in place not allowing them to be changed

the only way you get more hp out of shootout mode is putting your exhaust sensor near the Extractor manifold.Which is picked up then on the CORRECTIONS part of the dyno sheet.As well as tempertures of the day,Barametric pressure and Humidity.

If the dyno doesnt have shootout mode the variables such as ramp rates can be changed to suit different vehicles.

So i can say that your quote is wrong

373.5 hp doesnt = 130MPH

Yep Engine just got dynod

Made a total of 1231 HP

i was buying this for my Full chassis car but chose to use it in my STREET car

Don't kid yourself fool, you have no Full chasis car and your STREET car isn't registered or even driven to the strip and runs no exhaust, stop kidding yourself we're not idiots

Your lies don't impress anyone they just make you look like a DONKEY

and your STREET car isn't registered or even driven to the strip and runs no exhaust, stop kidding yourself we're not idiots

what makes you think its not rego`d

reason why it isnt drivin to the strip is that im from wollongong and if i break something it wil cost to much to get it back

As for the exhaust its dumped at the diff

and what makes you think i dont have a full chassis car im building

Edited by MR331307
Because your a DONKEY, its like your FULLY built spare RB25 that you post about but now your selling the stocker you post you can build it

Pretty easy to do a search and realise you don't remember your own lies from post to post

ive got the parts sitting there all ready

if you got such a big mouth and think you know everything come down to my shop and come check it out for yourself

or when i come back to the track

no need for silly remarks when you dont know me from a bar of soap

you might read this and that but i can assure you im using the standard motor and my other motor is ready for building machined and ready.

as for the race motor i have got it purchased and am awaiting arrival from it

it was assembled and dyno`d from another shop overseas

so many people on this forum can talk so much bad stuff about someone its not funny

to the people who have supported this thread thank you

to people who talk bad about the car and dont believe it

like i have stated the car is 80 % of the time at Wild 1 motorsport

go and view it

everyone is more then welcome

Edited by MR331307
ahhahahahhaahhahahahaha

yes i better anounce this

i borrowed my mates plates SCRMER

my plates are LNEMUP

im building his car

it has a Trust t88

Forged pistons,rods,crank,jun pump,Larger oil sump,GTR head,LARGE CAMS,custom cooler,Hydra ECU,1000cc injectors.

will be ready in 2 weeks

As for the rego why else would you need to borrow your mates plates? did you forget you posted that :):)

what your saying WAS true

but i was waiting on my engineers report before i could get the new Blue slip,Its rego`d now

all i gotta say is

later man

Before i go

shibby what car do you drive

Edited by MR331307
I ride a donkey

just asking

mate no need for silly remarks

See i wish to sponser or advertise on SAU

but people like you make me change my mind and lose interest

sometimes i think is it worth it to contribute and talk on these forums

they are well respected and alot of people use them for the right reasons i started off on the wrong foot but have learned to hold remarks in

    • I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!
    • Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.
    • The best part is when you own the car long enough that you look back and find your OWN ham fisted amateur shit!
    • The annoying part about neglect, is when you start to replace one thing, and find ten more broken things. Ham fisted monkey repairs you normally only find out about when trying to do something unrelated! Ha ha   Neglect you can kind of anticipate the huge costs to fix it all. Ham fistedness is normally a shock the first time your work on a new old car, as everything "looked" good before.
