600 rwhp (possible w/ported Eaton on)E85??`

[Posi]

I'll bench race with a bone stock longblock from SVT.......

My car made we'll say between 540-550hp the way it was setup with the 6spd in it. The car has every mod to get more out of the Eaton that's made on it.

so

Add cams which might be worth 30hp TOPS and it's probably more like 20hp unless someone tested, tested, and tested again to find a cam that's perfect. Up until now there isn't one.

so 540-550 + 20hp (better use 20 here) = 560 to 570 hp

now E-85 which can be 20-30hp

560-570 + 20-30hp = a very Bench racing friendly total of 580-600 hp corrected

I'll say it again also if you're not using a Dragon you won't make those numbers.

It's interesting reading some of these posts in this thread without substantiating the claims. Some people should stick to reading and learning instead of trying to educate people with misleading information or incorrect info.

For the record, I am shooting for 600 with the eaton, no nitrous, e85 or meth. I will be using race gas for those pulls and I will have another tune for street/pump gas.

Why just go TS to make 600? Seriously? Its too damn easy and everyone does it.

I don't like taking the easy route and doing what everyone else does. I like to do things that make you say damn, he really did that? I get that a lot when people realize I went 10's with the eaton with 3.31 gears and going through the traps in 3rd gear.

Yep there's nothing there. Tried what you're saying pretty much and even made a Dragon plenum to feed it. Car showed no gains compared to a regular Race Port. Same day testing and car stayed strapped down on the dyno.




What tb/plenum combo are you running? Has to be a Dragon on the Eaton if you're wanting the most hp/tq you can get out of it.




I'd love to see pictures of the blower you ported to see what all was done. Porting these things isn't Rocket Science but you gotta spend a ton of time on some very crucial areas or the car won't make max power and it'll hit its peak earlier in the rpm range and drop hp right after it without carrying it out. How much work did you do where the air enters the rotors? Did you work on the roofs transition or the rotor lead-ins on the floor? Did you drop the entire floor because you mentioned you would like to try it? By the way it doesn't do anything.

What tb/plenum combo was on the car and was it ported as well?

Plenty of people are unique and hope for even more than 550hp but typically they fall short. It takes every single mod known and a very thought out setup to get more hp out of an Eaton than everyone else gets.

To begin with, a majority of the work was around the area where the air enters the rotors. I basically put my head porting skills to use in reworking the inlet. This blower was poorly ported by the previous owner. So a majority of the work performed was to straighten out the crap, and improve what was already there. Supposedly, the previous owner made around 520 on it. I don't know how, because he had ground through the inlet in some areas and repaired it with JB Weld. Whenever, I got a hold of it, I removed the JB Weld, and had the holes welded. The port looks similar to yours, but has my own little touches, and unique features. I rework all the areas you mention, but I don't pull the lead in areas around the rotor bearings down nearly as far as you do in your ports. As far as the floor is concerned, no I did not straighten the floor out. I don't believe there is enough material to make it completely flat. So the floor had a slight uphill taper leading into the rotors, and I radius the sharp edge where the rotors meet the inlet on the roof.

The car has a Billetflow throttle body and plenum. I didn't port the plenum at all, I only gasket matched the plenum to the supercharger housing, and made sure the plenum was to size on the throttle body side.

Some information on the car. The dyno graph shows 520+ horsepower from 4750 RPM to 6200 RPM. 6200 RPM being the end of the dyno pull. It makes a slight peak horsepower of 548 at 5800 RPM. It makes over 550 foot pounds at 3100 RPM. Peak torque is 581 at 4500 RPM, and torque doesn't fall below 550 foot pounds until 5200 RPM.

600

We will find out. I have stage 3 crower cams springs. 60 lb injectors bassani headers. well actually bassani allthe way.stage 6 steggy. just got it back friday. accufab s/b tghrottle body and plenium.2.81 on top 4lb on the bottem sct 3000 maf. bbk cold air. 3.73 gears. kb boost a pump.the steggy is going on this week.the stock eaton is not a good match 4 big cams.kb mammath coming soon.

I like your thinking. A lot of people on here say, just go twin screw and make 600 hp. Where's the fun and sense of accomplishment in that? Not many people want to put the time and effort into making something do what other people say can't be done. Go luck to you, I hope you make their jaws drop!

 

[89slowgt331]

Jason, will have a very well running ported eaton combo, regardless of a piece of paper with a number it will show it's potential at the track I'm shure.
Good luck jason!
I will be getting my eaton, TB,Plenum back from my porter wednesday or thursday. it was a steg stage4 but I had a friend at roush open it up some, I will have before and after pictures.

 

[04gtstang]

I think the first "600RWHP" cars we will see are going to be from high elevation areas...and thats simply due to the correction factor used to make it sea level and the fact that blown engines do not loose nearly as much power as N/A engines...soooo inflated numbers. I remember seeing someone with like a non ported eaton making mid-low 500s....he was @ 5500' lol.

Personally I have established a goal of hitting 600RWHP SAE with the eaton (everyone else has only done it STD)...and im only 400-500' above sea level so shouldnt be too much difference in numbers. MAJOR portwork revison to come soon...Im going after it with a stock long block as well, just to push myself even harder. I dont expect to hit the numbers on my first attempt, but my gears are always turning and as said, failure will force me to succeed.

Since you didn't say Eaton M112 I will say yes

COBRA ENGINEERING

Guy made 613rwhp with a Posi Port, with E85 I'm sure you could make more.

Nice try, we knocked that out a while ago. Of course that link refers to an M122, which you are actually referring to.

Well, I'd love to give this a shot But, I got the Kenne Bell 2.2 I might be throwing on later this year for the rest of my build this year, However...Lets just say you used my car for pure testing purposes, Without cams I don't think I'd make it. I'd come up pretty short I'd reckon. But with say a 2.65 / 4lb With my Ported Eaton + Ported Dragon + Full E85 I would hit around 570 or 580 Range with timing of 25+ I know that sounds like some pretty aggressive timing but I do believe its doable.


Now if you Really want 600+ RWHP on a Eaton without Cams and you are already on the corn burning route you always can bump up to E89 or E98 or even your custom blend of Ethanol and gas. That should also give you more room for timing advance, Even 27+ Perhaps. I do believe its temporarily cheaper then shelling out money for high stage Comp cams, Installation, Etc.

But thats my views on it. I'm saying it would probably get you there, Just not sure your car would live all too long.


Edit: I'm curious if you could run 100% E100 Blend, I would not know, I'm curious however.

I have heard of 540 rwhp on e85 upper only no port.

Got a graph and where was it dyno'd? How much timing and what was the a/f ratio?

Here's a link to the graph. Air Fuel ratio is right at 12.0. Don't know what the timing is set at.

Well we all know that guy knows how to tune 03/04's that's for sure. See if he knows the corrected numbers because it says standard on that sheet. Either way the port works and someone did a great job.:beer:

I'll see if he can find out. Don't know if he will or not. All I know is, when we took up the street after the tuning, and my friend got on it; I couldn't believe it. I told him it wasn't safe for the street anymore. If he just blips the throttle the car just bucks from the weight transfer. I told him if he's not careful, he'll break something that way. And if he was going to get on it in first gear, he's going to have to commit to it and put it on the floor. None of this part throttle mess. To be honest, I'm more impressed with the torque than the power it made.

Ah the infamous "STD" numbers. Heck mine put down almost 530 STD.
BTW Posi, "STD" is considered a corrected number. DIN, EEC, JIS, SAE, and STD are all established correction factors...they just use different "standard day conditions" per sey and thus the amount of correction to the number differes.

Oddly enough STD is atleast IMHO (coming from an aviation background) the CORRECT one we should be using. 59*F, 29.92 inHG, 0RH (sea level) is the assumption...thats exactly what all aviation performance is based on and what we consider a standard day.

SAE is newer and comes from the auto manufactures...they decided to base it off a standard day in DETROIT where the cars um used to be made... 77*F, 29.235 inHg, 0% RH

Dont know if you wanted to know all that lol, but I used to be hard core SAE...but now im not sure. I dont care what my car could do in detroit, id rather know how it would perform @ sea level at the average global surface temperature of around 59*s. :beer:

BTW going to shoot you a PM on the dragon inlet setup...thinking about getting one.

 

[jalock87]

Im currently doing a build and planning on trying to hit the 600hp mark with an eaton....eventually. For now im building a teksid that is going to be in the 10.5-11 :1 compression range. The blower is a posi port with a ported tb/pl. I will be limited on fuel for now running dual fpdm/GT pump, BAP, 60# inj, and on E85. My boost levels will probably be moderate for now at 14-15 lbs. I also plan on running the snow stage II MAF kit pre blower to keep the IATs to a minimum. I have seen a posi port based eaton car in Texas that made 575hp with the ported dragon, same fuel, boost at 16-17 lbs, and 25* timing on stock compression. My goal is with the higher compression to be able to spin the eaton still at a somewhat normal speed and reach the compression needed in the cylinders to make this kind of power. Of course I know there will need to be some more supporting mods, but I think this will be a realistic goal if I can get the cooling I need to run a decent amount of timing. Anyone else think this is realistic?

your going to need more fuel for e85, even with an eaton. That is alot of compression. I say you'll need 80# injectors, and I would for sure do a return fuel system with at least -8 feed/return lines and 2 or 3 255lph pumps.

I understand but SAE or Corrected is what everyone goes off of in the automotive community. STD numbers are higher and show more hp to help sell parts or to say hey look at these big numbers. Most people on this site don't care about STD numbers and I'm sure it will stay that way.

Got your pm and replied.

I agree thats what people use it for unfortunatly. It would take a global change and yea no way thats going to happen...I just dont view STD as a crap correction like I used to, it was the original and most accurate in terms of world averages and still in use by the strictest group out there, FAA/aviation.

BTW thanks for the quick reply :rockon:
