Re: USAC RPM Story
I am not an engine guy, just a crew chief & racer who runs an esslinger XT.
It seems that to me the issue of RPMs, with respect to an Esslinger is more about where you are in the RPM/power band getting off the corner? Not at the end of the straight for a brief moment. Given they are torque challenged on short tight tracks. How many guys really run IRP, Iowa or Phoenix? Why all the emphasis on HP developed? Yes its a means of measurement. However we found we turn up the RPM's when competing to get up on the cam or the torque curve to get off the corner better. So I have to ask doesnt any one think the R & D guys down there dont know what to do cam wise and phasing wise to shift the power band down in the range now allowed by this rule? Bet they do or they will find it this winter. Remember when NASCAR instituted RPM limits? Do those motors make any less HP? Nope.... theyre better than even before and all it took was lots money. So.... I think the big guys will send their motors in late winter to get those R & D benefits. Sorry if I didnt offer a solution but I dont think this new rule is the right one in this case. Maybe it will help the pushrod motors live longer but.....Wont save any money for guys who own the stuff already. Just my .02 cents worth. |

Other than the top national teams, I do not think the majority of midget racers have motors more than $20,000, there are ALOT of $10,000 to $15,000 motors being used and are competitive. (I took this from one of my previous posts because I am to lazy to type it all) The demise of midget racing is more of a preceived problem rather than reality. Given that midgets are a touring series and have no local weekly racers to drawn upon for their shows and yet they get 25 to 35 midgets in this economy is quite amazing. The WOO would only get about 15 cars if not for the local weekly racers to draw from for their shows. If tommorrow a $8,000 midget engine was available that produced 320 HP and did not need to be rebuilt for at least two seasons there still would be only a marginal increase in midget car counts over the next couple of years. Why, because ENGINES are not the MAIN issue and things such as tires, travel (because no weekly programs) testing, etc. |

We plan to be on the scene with an upgraded version of the RRE ECOtec as well. Our objective is, and always has been, to provide a modern, state of the art engine featuring improved fuel efficiency, longer duty cycle and better driveability at lower cost than conventional designs. Our current engine features a factory stock rotating assembly and sells for $11K, air filter to muffler. It has proven to be perhaps a little better than we expected vs. traditional Midgets even though that is not what it was designed for. Our ST2 engine will be intended to run competitively with the Esslinger EST and ST.
The ECOtec has tremendous potential. What we want to do, is bring something out that is competitive, durable and very affordable. We don't want to turn this into yet another very high powered, expensive, fragile Midget engine. What would be the point of that? So, our hope here is that somehow, some sanity will return to Midget racing and an engine capable of running with the 330HP ST/EST motor will be all you need to go have some fun and be competitive. If we can find a way to do that, I think the sport can start growing again. |

That crank, after polishing and rebalancing, is supporting over 400HP in several applications right now.
The MEFI 5A supports variable camshaft timing, multiple event sequential fuel injection, multiple event sequential ignition timing, fully interactive acceleration/deceleration enrichment/enleanment routines and many, MANY more highly sophisticated technologies. The problem with MEFI 5A has not been with the controller, it's been with the calibration software. We have that resolved. I have produced hundreds of engines using the Electromotive HPX. I know they guys at Electromotive well - they are great people and they produce an outstanding product. When I began the ECOtec project I fully expected to be doing it with the Electromotive system and the ONLY reason I'm not using it is that the MEFI 5A, as pertains to the ECOtec at least, is a FAR better controller. The fact that it also happens to costs a lot less was just icing on the cake. If there was a better controller on the market for this application, I would be using it. We certainly will need to change and/or modify a lot of stuff to catch up with the 'big boys', but the crank and the controller are actually a couple of the items that are good to go.
