hi,
do anyone know what is the limit in power for the stock turbos in non sec mode with pfc?
i am asking that because the seller of a car claims that has 360hp at the wheel on dyno.
the mods are:
removed cat and pre cat. greddy catback.
new intercooler.
i do not know about the injectors.
assume that he used the bigest ingectors he could .
pfc.

please note that the car is for street use. so i am asking the max hp for reliable and safe operation.

thanks

~360whp is the bleeding edge of reliability for the stock twins. Depending on the other mods the car has he's probably running about 14-16psi.

Did he say what kind of fuel he was using? That can make a big difference when you are that close to the edge.

360 on stock twins would be a pretty modded car. Exhaust, intake, intercooler, and injectors likely wouldn't do it. Engine needs porting etc. Typically those mods will get more like 300-320

without knowing the full mod list, it's hard to know if that number is real or not.

anyway, i made 380 to the wheels on the stockers...pretty modified though.

i've been running my twins at 1 bar for almost a year now. still boosting strong.

Right mods and a dynopack might get you there.

Ask at what boost level.

BoostCrzy

This largely depends on the dyno and settings tested...on a dynojet....you will be around 330-340whp.....on a Mustang dyno...300-315whp....Dynapack will get you 350-360hp...(measures at the hubs with wheels removed...) ....so take your pick...lol...but the true test is at the track...trap speed vs. weight doesnt lie...

I've only tried a mustang dyno and as you pointed out they will give the lowest rating. My car did 290whp @ 15psi. While I have not done the fuel pump mod I did hit 100% injector duty.

Without making some changes to the fuel system this is pretty close to my cars limits.

For what its worth with weather correction they said my car did 302whp.

quoting myself.

my 380 pull was on a Dynocom in-ground dyno.

Can you elaborate on what the RE-A power expander is? That appears to be a lot of power for just full exhaust and intercooler upgrade.

really!!!!!????

hello

Actually our Power Expander is very effective.
But Just replacing this downpipe cannot generate 400 HP + .
Today we set up one customer's cat with the same mods.
His car marks 402 HP and 47.6Kg.m torque.

Stock twins with standard bolt-ons making 408 whp at 14.5 psi?

That would be the highest number ever reported for stock twins. (And, if I recall, other ~400whp reports were running the twins at 18+ psi.)

Hello

I've received PM just about 400 HP+ and the Power Expander.

I have to say again, just replacing the Power Expander cannot generate 400+ HP.

But Our Power Expander is very effective.
With the stock downpipe, EX pressure is too high.
We have modified this downpipe some times.
Then, we can get the more power than before.

It appears to be a downpipe... albiet a very nice looking one. I'm sure it is very good, but I am curious to know how 400 whp was achieved with full exhaust and an intercooler upgrade. What sort of electronics/tuning was done?

What is your secret??!

Try giving a PM to GoodfellaFD3S.... he made somewhere around 421hp on non-seq

he might still remember all what he had.

weren't those B&R turbos?

yeah those were BNR stages III's, which aren't exactly stock turbos.
