What boost or psi are you running
 

Hi all

Want to get some clear figures and numbers .
List your engines and mods too.
Really want newage sti 2 litre and what boost it can take on standard engine as ive herd of ones running over 500 hp on standard internals and don't hear any of letting go ?
Obviously if the thread takes off all engines etc welcome as will help others
So I want a list of facts please
Thanks Mick

I'm in a classic but running a JDM STI V9 bottom end. Mixed with a TD05 20G at 1.6 bar boost max. Touching 400 with no problems, yet...lol.
Very strong engine the newage STI lumps, just ask Banny. Sure he's at over 2 bar on his standard engine and huge turbo.

500 bhp on standard internals??!!!! I don't know if that is safe but I have a good friend of mine that owns a subaru sti MY05 2lt engine and is currently at 415bhp and everything is perfectly safe. He is using a FP68HTA turbo with appropriate supporting mods (injectors/radiators etc)

Broken the car now but it was 523bhp @ 2bar boost for about 10 months :D

2.33 Bar (MAP)

2003 sti ppp.
panel filter
Fitted H&S straight through in place of resonator.
300hp

2.5 litre sti decat, panel filter,safe map, 1.4 bar, 340 bhp,360 torque, makes a very nice smooth fast road car, 62000 miles no engine problems and can achieve 30 mpg.

Banny did it break or have you just broke your car ie in bits and sold as wanna no how far I can push it
Dave 2.3 bar and 300 hp ? How come

this makes me laugh. 500 hp on standard internals. on a 2 litre as well.

Why do you laugh ? Read replys above
The spelling?

2.3 bar map is 1.3 bar actual which is about right for 300hp

Broke the whole car for bits, engine was still going strong. Was running a rotated GT30R 0.82 housing and on the road boost did peak at 2.09bar

there is not one car quoted above running over 500hp on a 2.0 litre. have you even any idea how much it costs to build a genuine 500hp car? 500 hp on standard subaru internals, that will last all of 5 minutes.

Sinky mine was a standard newage 2 litre with sti heads, I used 15% meth to get my final figures.......

oh, ok sorry about that i thought your were running a 2.33. and you kept it together for 10 months. did you drive it like a granny banny?

That is the reason I broke it, new car is a version 5 sti type r with a 2.33 and a billet 35r :thumb:

Hammered **** out of it at every opportunity, sometimes didnt even wait for it to warm up lol

Thanks Banny for the info I asked for in this thread :-)

I am running a too sensible 1 bar. My car is old and I need to look after it :(

But I do have a Greddy manual boost controller on my steering colomn :Suspiciou lol

https://www.scoobynet.com/projects-4...ly-driver.html :wonder:

at over 2bar im amazed it ran for ten months, makes you wonder how long oit would last at 1.8 instead, bet would be in the years.

A bit of a warning to all, don't get hung up too much on what boost, mapper will optimise it for best power/reliability. Too high boost and you will break the engine eventualy, be it 10 days or 10 months it will let go.

try that on 10 cars and a high number will let go. I doubt any tuner will advise you it being safe to run anywhere near that.

but you pays your money you makes your choice.

Banny's car didn't break after 10 months. He broke it for bits...
If a car is setup properly by the mapper then you'll be amazed at what you can run safely.

That's the whole point of the thread guys
The facts only
No slagging off etc please
No need .

ahh sorry misred that lol

but as said i don't think you'll find many folks who build high volumes of engines who will go that far without a very big warning and refusing any comback if it goes wrong.

um, i dont think there was any slagging off was there?

its a pretty common discussion this. If there were easy answers it would be answered lol :lol1:

1.8bar for me, any less than that is pretty ghey tbh ... forged bits in a 2.0 litre, md321t, 740 injectors etc.

TX.

Fact is it's ALL in the mapping. A 300bhp badly mapped newage lump will go pop, whereas a car mapped by one of the best (Paul at Zen for me) will run 400 quite safely. And in some cases 500+ as many have proved.
Ofcourse they need to be cared for too but that's a given.

STD 2002 STI + AET-Turbos, std. fit GT3076 hybrid @ 2+ bar for the last year or so...

Last time JGM checked her over he said there was no knock...

GRD made over 500 bhp on a std. STI lump, IIRC.

dunx

P.S. Had some issues with the ecu claiming BCS failure in 6th gear Wu ha ha !

Brill info guys thanks and keep it coming

In reply to some of the posts above I'm @ 1.55 bar 420/450 hp on 20% meth
