Has anyone hit 1000+ WHP on any EJ motor?

[700hp]

I'm sure by this point that their new 3.3 litre drag car has hit over 1k hp. They are in the 7's with it and it is the same car that they used to run 8's with only rwd and big slicks etc. As far as the weight of the old drag car I'll bet it wasn't much at all below 2500lb. It started out from the factory at around 2600lb and yes it was gutted out but dont forget about the cage, monster turbo, intercooler, dry sump system, ford 9" rear end, etc. these mods could easily add back hundreds of pounds. Regardless they do an awesome job, and have helped me quite a bit with my current build.

bump for a 4 banger boxer 1000 whp!!!

well darton says someone has done it...or so they said at pri without dropping a name...said it was a 1048 iirc...but being no credible evidence and them trying to sell a product, well I'll leave that up to youl.

You know I understand it takes power to go fast. What I dont understand is why you want to make XX power. I can understand if you want to run you know a mid 6 or 10 flat. You have to focus on the entire car. Your gear ratios, suspension, and all supporting mods all work together to make the car run your goal times. Making XX power doesnt mean you will run Y time with just power.

Maybe someone can enlighten me.

[700hp]

^^ True. I believed with my sti that I just needed to make big power and it would make my car fast and it did but it didn't make it that quick because I did nothing with suspension, tires, tranny, etc. 678 hp & 10.9 @ 138 is just retarded. If everything else had been done the car could have run low 10's. With my new build I have tried to focus on the car as a whole taking weight into concideration heavily and I modified suspension went with an auto tranny and slicks etc. The car has only dyno'd 620hp so far (but with an auto this should be more like 7xx at the crank) but maybe this is all the power I need to run the times I am shooting for. This time around I am trying not to focus so hard on a big power # but just trying to get down the track fast. First time out she ran a 10.8 with only 18 psi so I'm already faster than the last car I built. And to stay on track with this thread I don't think My car will ever see 1k hp. It would be nice - but is it necessary?

I think it is more because people have been watching a few too many single turbo Supra videos

People will have a very difficult time hitting this mark until someone redesigns the head castings to remove the dog-leg exhaust runners. You simply cannot hope to make comparable power to Hondas & 4G63s without comparable equipment. Sad thing is that this is probably up to Subaru alone and they haven't been very good lately in giving the hardcore community what they want. This is the biggest stumbling block to me because it is the hardest to fix.

Right behind this in #2 position is the oiling problems mentioned by others. You need 9500RPM to make that kind of power on a 4cyl, and this is something that seems to be escaping most builders at this point. Some have done it, but hold their cards close.

well, just to inform you, I know that myself and one individual have out dogleg ports outflowing out straight exhuast ports

just to let you know, that is B.S.
2.0L motors have been doing it at 9k

Its the exhaust side. That is not nearly as important as the intake side.

So what if you can make 1kHP from a 4g63 or a honda. What times are they running. There are street DSMs running what mid 6s now. They have to make alot more power than a suby. There drive loss is horrible. Power goes to the center than the front so it sucks about 5% more power. Then you have a FWD honda. That is its only purpose. It cant be street driven unlike the DSM. Both are also very expensive.

My point is that subaru doesnt make a inferior product. It takes alot to make it to that point. Mostly alot of money, time and experimenting. Dont think that these motors last for 200K miles either. They might go 10-20k before being torn down.

If you want to go fast the EJ isnt it. Way too expensive when a EG33 fits with little trouble. You can build that motor with just pistons and rods for the most part without anything super special or expensive. That would easily take 1kHP with much less work and be much more streetable. This exact thing has been done to make some of the fastest subys in Oz. That is something you cant do with a 4G63 car or a honda without remaking the basic car.

the exhaust side is very portant...if you can't exhale, you can't inhale

I also definately would remove that easy...you can make it more easily because you have 50% more holes to fire on but do run into a head port/cam limitation.

[kay95]

Well I say it isnt as important because you will loss less power with a open exhaust. The piston will push out what ever is in there. However on the intake stroke even with boost you might not fill the cylinder to the fullest.

My point is even if you opened the exhaust you will only make so much more power. If you open the intake side up you will make more power til you stop flowing more on the intake port.


You have 50% more displacement. When I said easy I mean you wouldnt have to spin it to 9K, have a special expensive custom piston with a thick crown and titanium rods. You wouldnt have to run a dry sump or use dart liners.

What limits you on the heads and cams? The head arent bad and neither are the cams. Though you can get the cams welded up and work the heads some. Though it isnt as important to get the ports to flow what a cosworth or cobb head because you have two more cylinders to breath through. If you can make 615whp on stock WRX heads and cams I dont see why you couldnt make 1000whp on a worked over EG33.

[shvrdavid]

The biggest problem I have found in the Subaru heads is not what most people would think of...
Take a stock or a ported head... Put it on a flow bench and simulate the piston and the valves at equal overlap for the cams you are running...
Now Wet flow it both directions...
It flows better the wrong direction... And the pressures that is will see during operation only make it worse...

One thing that always bothered me about porting, is that many people who do it, never ask what cam you are going to run...
If they don't know the cam, how it is degreed, and application pressures...
How can the effectively port the head???
Many people port heads on a flow bench and forget to check the ports in reverse (the should flow far less in reverse) and most have never even thought to check overlap flow at the pressure ratios that they will see in operation...

I hear people saying that dogleg ports don't flow...
Tell that to any V8 with splayed valve heads...
Mark IV Big Block Chevys have 2 dogleg, and 2 strait intake runners in each head... And the doglegs outflow the strait ones most of the time...

There are other engines that have the similar setups on the exhaust, and the doglegs outflow the strait ones... I can think of 2 and 4 valve examples of this...

Doglegs have the potential to outflow strait ports for many reasons...

The reason that the Subaru dogleg doesn't flow well has to due with the port turning too early, not the fact that it turns...
This sets up turbulence in the runners that restrict flow thru one of the exhaust valves due to incorrect merge timing in the main port...

And there is a way around both of these problems on the Subaru head...

It just requires a lot of experimenting...

These engines just need more time for the kinks to be worked out to get more power out of them, and it will happen...

All it takes are guys like us who try new things...

Think outside the box, and you will be surprised what you come up with...

1000 whp isn't asking a lot, all it takes is time...

Heck, I remember when people said that top fuel would never break 2000 hp...
And now they are knocking on 8000's door...

It's only a matter of time.

The way things are going I'm not sure IC engines making this power are going to be around much longer... regulation is coming guys! For the street anyways. I have seen an electric mustang with 2000 lb ft which was pretty cool in it's own right

[03whitegsr]

What RPM was that 2000 lb-ft at though???

Electric motors don't have a problem with torque. Stall the motor and you have all kinds of torque. That back EMF is a beotch though...

[sperry7]

No idea what rpm. Does it matter? 600 hp + 2000 lb/ft = ridiculous fast. I'm speaking of the ronaele cars. (Eleanor backwards- kinda stupid)

yeah, it matters a lot where the 2000 lb-ft occurs as electric motors have max torque at 0 rpm and max hp at max rpm....so think about it.

anyhow, I'm sure that the 1000whp mark will get broken and publically posted not too far from now as I know of several rediculous builds that are happening. Only a matter of time until the tweaks get worked out.

[Sinister redlines]

I too have made my dogleg ports flow better on my flowbench. In fact thats where started (after installing bigger valves and seats) and then balanced the two ports out. Then balance all the ports to the same flow.

Have you check the flow of the ports both directions???

And have you checked the overlap flow in both directions???

how are you going to spool entirely to get the 1000 hp froma 20 mph roll?? itd just redline before 10 psi lol.. and thats going up a hill

-Could you list and explain some exhaust examples (and flowtest pressure) to show us what you have come with there?

-are you flowtesting the exhaust with or without anything attached to the head?

innovative tuning was bending the chassis on their bc legacy with a gt35r on it and spinnin teh tires from a 2nd gear roll

but his setup was non intercooled so i think he had alotta `torque on tap

[kasra007]

This is pointless.. when it gets to the point where daily driving the car is not possible.. its a waste of time and money. I would want to daily drive the car ^_^
