The OFFICIAL Eddie Bello engine combination SPECULATION thread

Hope Eddie gets a kick out of this...

Figured since he will never let us know how he achieves so much power from a 2-valve, air-cooled engine, wanted to see what you guys think would be the recipe for such high power?

Here's mine:

1. >30 lbs of boost possibly over 40
2. 4.0L
3. 1 3/4" or 1 7/8" header primaries with T3 possibly T4 flanges
4. Heads welded to cam towers for extreme boost levels
5. 0.600+ lift cams with over 300 degrees duration
6. Xtreme heads or many hours porting 3.6 heads and flow bench testing them
7. E85, VP race fuel, or VP mixed with high octane pump gas
8. Methanol injection

What's your speculative recipe???

There already mentioned that he uses ethanol as fuel.

I would add excellent tuning, good turbos+intercooler also to the list.

IMHO the boost does not need to be so high, my bet would be ~30 psi.

Seeing how he can really drive the car on the street, the cams are not too wild also.

While I am not going to pretend to be really in the know, even though I am regarding his gearbox Eddie has shared bits and pieces with me because it is relevant to the gearbox, among other things.

A car like this has one cornerstone. Tune tune tune. It is why he can drive it on the street. It it why he can have such huge variances in trap speeds throughout the weekend of the recent invitational event. And why a car like this is so durable. he doesn't stress it anymore than what it takes to win. And while some of those other cars had hundreds more horsepower than he did, I suspect Eddie often had 200-300 more hp than they did at lower rpms because he has a tune with less peaky boost and more consistent power across the range.

He can change his power levels and tune in every gear and on the fly. And that is part of what blows my mind. The guy is covering 1/4 mi in less than 10 seconds, doing over 170mph at the end and is making adjustments 5 seconds into it!!! And people say straight line racing doesn't take skill. Hah!

I have always said that standaolne EFI is the only choice for extreme performance.

Gear based boost/ignition/fuel control is a feature that pretty much every decent ECU has, though not many people know how to tune it properly nor willing to spend time for this.

I would like to hear more about this and what adjustments can be made on the fly. Only thing that comes to mind is a boost controller. Any other detuning features of fully programmable EFI sounds impossible to detune on the fly unless I'm forgetting something????

He is good at what he does and I would agree a good tune can go a long way.

Technology exists allowing for multiple preset tunes to be chosen with the push of a button. Perhaps he can just push a button while on the move for a desired effect?

That's what I'm trying to figure out. I mean, you wouldn't lean out or richen to change power, maybe retard timing, but how would that be done on the fly?

Only thing that I think is a solid way to detune is a simple boost controller.

I bet Eddie has a good laugh when he reads all of the threads like this on all the forums, everyone tries to guess his perfect cocktail of an engine build.

Read my above post. Decent engine management systems all have gear dependant boost/timing etc controls. Which means that when driver changes gear, preprogrammed boost level, advance etc will be applied.
Gear is detected as a function of rpm vs road speed (non-driven wheel).
I have done this personally on several cars.

Matt is talking about "on the fly", you're talking about preprogrammed. I can program my boost levels per gear in TunerStudio, but i believe that's not what Matt was stating.

Ok, let's say the recipe I put is going over (spec wise) what Eddie has. Wonder what the hp/tq potential of my recipe would be??

This would explain how he can launch so well and then do roll on wheelies in 2nd.

I will make the example of the 9ff cars that have gotten a fair bit of press. They have a button on the steering wheel that the driver presses as he goes through the gears.
2nd gear limited at 600whp, 3rd limited at 750whp, 4th at 900whp, etc.
Do you think that with just more boost? Of course not. They have to adjust fuel and timing to match that increase in boost. More boost without more fuel is gonna go lean with huge egts, etc etc.

It is a system. If Eddie only dials back 5th gear boost once he is sure he beat the guy, wouldn't the car go stupid pig rich? Wouldn't it shoot flames or show some other external sign that the only change is 3-5 less psi of boost?

Now mind you Eddie has told me nothing of what his electronics are or exactly how he controls it. But I am pretty sure that he is controlling more than just boost when he makes changes on the fly.

Just changing boost is very 1986...

little known facts, makes it perrrrrfectly clear:

- Eddie's car burns refined mixtures of Chuck Norris' sweat
- Eddie's car spontaneously grows a beard 1/2way down the strip
- Eddie's car has a motor strung together with Lumberjack axes and chest hair
- Eddie's car has an intake which ingests Leprechaun fetuses and angel wings

it's all pretty simple really...
