Max Hp Out Of Standard Rb25

[paulr33]

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.

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.

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.

1200hp from a donkey?

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

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

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
