Hi,sure you can get big horse power from a 2 litre engine (2.2) on a dyno
for less than a second,but what's the point. I deeply suspect the 900 hp
test on the dyno, I sponsored several racing cars since the 80's . A Cosworth
RS500, a Subaru rally car,and in the BOSS league (old formula 1 cars).
The BOSS car was a Lola Beatrice which had an engine under 2 liter. It had a solid engine (non removable head) it had an enormous turbo and ran 5 bar
of boost to achieve around 950hp. So the dyno test with 2.7 bar is only going to give around 450-500 hp max. An ordinary Evo 8 with 350bhp is going to give you a hard time anyway because of power to weight and handling.
I sat at many a dyno with guys straining out the last hp, but the power has got to last a race or 2, so no good having extreme power for under a second.

 

Where you been?

 

No I understand what you are saying, but I'm sure a 900hp Evo isnt being set up for a road course. One second at 900hp in 3rd gear for a drag built evo is the difference between what 8-9seconds ET? I agree with you that its never worth trying to destroy your engine to bleed that last 3hp from your engine. My car isnt near that power, but I do have 400whp out of my STi at 19psi of boost with EGT's of only 1450. Although I know I can get more out of it with out it straining.. I like to have a long flat curve rather than just a peak number. I would guess most Evo's being driven have an excess of 350bhp... more like 350whp.

 

Dude do you know that 1bar of boost equals 14psi?

So in essence you r saying that your car ran 5bars which equals 70 psi to make 950hp?

Your whole story smells fishy, and by the way my mitsubishi at only 1.5 bar (21psi)on pump gas put down 413whp.
Please explain how 2.7bar(35psi) only 450hp?

 

I thunk'ed he was talking about the Boss rally car

 

I'm always here, the real question is..... where have YOU been. Hows the 63 doin?

 

Hi a standard Evo with 276 bhp is running around 1 bar, yes I know it's 14lbs.
The engine on the dyno producing over 900 hp is running 2.7 bar. So basically another 1.7 bar over standard, which is around another 28lbs boost.
Now 1 lb boost equates to approx 10hp in that size engine , so another 280bhp add to 276 is 556 bhp. Now cams and other things will increase it further
but not to 900 hp. My Formula 1 car ran at 5 bar of boost with race cams,
a much more special engine than the evo and that made around 900hp.
For all those STi drivers if your running more than 320bhp watch you pistons,
we use to change to Cosworth, but they are a little noisey but tough as old boots.

 

My Evo 6 running 1,5 bar had 330 bhp, where did you get your figure, was
it plucked out of the air, or did the guy who increased your boost embelish it.

 

Speaking of fishy.. That must be on race gas.

Ring lands are good to about 400whp. I have new short blocks being made for my car as we speak.

BTW my STi is on pump gas, 93 octane 377whp @19psi. Race gas 450whp @ 21psi.

 

Of course it ran on race gas, it was a Formula One car, not an Evo.
And in case you didn't realize it high octane or race gas is used for not necessarily incresing bhp it;s used to stop detination which will destroy
your engine. I will repeat, the only way to get big hp is to run more boost.
21 lbs of boost in a 2 litre engine will give a max of 330-350 bhp. And
for that to be reiable you will need steelcrank,rods and forged pistons.
You will have to upgrade your ecu to something like a Motec.
Big horse power is expensive.

 

The race gas comment was to project c55, not you. I'm aware of the use of race gas. If you are talking to me, you have me confused. I have a 2.5l engine and in a Subaru, 21lbs of boost will give you about 280-300WHP not bhp on a 2.0l engine(I had a VF34 on 2.0l WRX and had 285WHP with supporting mods. For the STi engines, you really are pretty safe in terms of reliability as long as you dont exceed 400whp.

The Cobb Engine management works well but has its limits, the Hydra Nemisis is the choice for most subaru tuners for high HP engines (600whp+)

 

No kidding!! Mr. Holden was quite anxious to race, wtf happened???

 

I guess he's ducking me? I saw his offer, pm'd cellio # we talked, he then tried to set up 1/4 mile run but I said "were NO where near a track plus you live 30min away, also I know of great spots to run multi-frwy rolls where the po-po don't frequent" he then said "ok. I'll call you soon...."

Nothing then he pops up here again stating your boy Sean wants to roll my 485 rwhp goat etc...I then repeat when? where? hmmmmm I still want to do this I'm 100% ready tmara?? you name the time WH

I wonder if he's done a lil' research & realized it'll be a close race, curb weight is in his favor @ around 3800 stk then add supercharger lbs he's prolly kissing 4000lbs & were close in rwhp but NOT RWTO Hell even if I loose I'd still love to run'em...

Edit: His last post above was posted 9/25 I just checked & he was on the boards 10/3 after midnite....

 

Sorry if I got you mixed up. I was only trying to get over the fact that to get
massive power figures you need to run very high boost pressure. Some people
think that changing the air filters and putting in high octane gas will give
much more hp without upping the boost.I ran a STi stroked to 2.2, with
steel crank, rods and cosworth pistons. It had a Motec ecu and I believe
ran 1.8 bar. One of the quickest cars I ever had, I also had Evo's but never
managed to get one as quick as the STi. What do you mean by WHP as apposed to BHP.

 

WHP is the "wheel horse power" I am assuming that it is an american term? That is how we measure power to the wheels.
BHP is usually "break horse power" which is the amount of HP that the car has before drivetrain loss. By US standards

 

Yes it is an American term. We just use BHP and on a rolling road the computer gives you a figure that would be at the flywheel.
However turbo cars on rolling roads need huge cooling fans to re-create
the air coming in at high speed.

 

Awesome, we use the same things its called a dynojet dynonometer. But does your BHP subtract for drive train loss?

Example:

Subaru says my 2.5l Sti has 300bhp, I can take it to get tested I will have about 240whp(power to the wheels after drivetrain loss.)

 

Yes I am sure our rolling roads allow for everything inc drive train etc, to give
a flywheel figure. But as I said turbo engines get VERY hot on rolling roads and you have to leave a big cooling time for each run otherwise the bhp figure starts to drop with heat.

 

It's on race gas. What's so fishy about that? Please tell me?

 

Because your post said it was on pump 410hp@21psi, which is fishy(unbelieveable).

 

A.D.D.: You can go to jail if the other car wrecks (for 10 years).



Whole story:

A jury Thursday found Lorin Franco, 23, guilty of gross vehicular manslaughter and felony hit and run in connection with the death of an Oxnard motorist two years ago.

Henry Chavez, 23, died while allegedly racing with the Ventura woman on Highway 101 in Oxnard on June 6, 2006.

Ventura County Superior Court Judge Edward Brodie set the sentencing for Nov. 12.

A witness testified that Chavez's Mustang struck a vehicle on the on-ramp at Rice Avenue, flew into the air, hit a tree, went over a fence, hit a steel plow and landed upside down in a strawberry field.

Prosecutor Tate McCallister said the two vehicles were traveling southbound at a high rate of speed in moderate traffic.

"Witnesses had them going as high as over a 100, maybe even 110, 115 miles an hour," he said.

"There were multiple witnesses who saw different parts of the race from Esplanade (shopping center) all the way to Rice Avenue."

Franco could be put on probation or sent to prison for up to 11 years.

"The judge has a wide range of discretion," McCallister said.

In an interview, Franco's lawyer, Tim Quinn, said he and his client were surprised by the jurors' verdicts.

Quinn had argued during closing arguments that his client's conduct didn't amount to gross negligence. He told jurors that she didn't know she had been in an accident, so she surmised that there was no reason to call police.

McCallister said street racing is "extremely dangerous" conduct, however it's all too common in Southern California.

"In this case, the victim was a willing participant in the street race, but we will go after everyone who is involved, and Lorin Franco was involved and was a significant cause of Henry Chavez's death," McCallister said. He said Franco and Chavez didn't know each other.

Franco continued south after the accident, authorities said. California Highway Patrol officers arrested her in Camarillo.:bomb:

You have pm...

 

Try 413 awhp @20lbs boost on 93 octane. Yes! Pump GAS!!! This is nothing for an EVO or DSM to do on pump gas. I can show you dynos and threads where some are making even more whp on pump gas. All based on mods and tuning.

It's not a Subaru dude.

 

How about comparing your mods vs my mods I think that would make more sense no?

 

Yes, what are your mods. Please state every last one. I'm very curious.
