@@jeshkam And you have built how many engines? And less than 50% of electric motors have ball or roller bearings. Many two cycle engines use roller bearings. Friction robs 25% of power from the engine. Cooling system another 25%. Of bearing/ring friction only about 35% can be retrieved. But that is about 9% increase over all. In the 600 HP realm that equates to 54 HP increase, without increasing thermal load. Higher RPM means higher HP. Lighter PR's mean higher RPM.

That would be closely guarded specs owned by Penske and probably adapted by MB.

[@bloqk16]

Aside from the pros and cons of whether or not Penske used a "loophole" for the design and building of the 500i engine; I always admired the guy for his innovative work that could take non-competitive racing cars and make them competitive. If the Mark Donohue book is still available, "The Unfair Advantage," I highly recommend that book which gives insights into the early years of Penske Racing. Penske challenge in NASCAR was making the American Motors Matador sedan competitive. He succeeded to get a victory for American Motors at the Riverside 500 stock car road race . . . not from some magic with getting more horsepower out of the engine, but to install the largest disc brakes possible in the sedan . . . while all the other NASCAR regulars were still using drum brakes, the disc brakes were not subject to fade late in the race . . . so the Donohue driven Matador was still racing the last 25 laps at the same speeds as it was in the first 25 laps. Penske took the brakes one step further with installing a quick-change apparatus on the car so that all the brake pads could be changed in a minute. When I read that book some 40-plus years ago, it inspired me to approach challenges from "outside the box" to solving issues . . . where it served me well in various workplace projects; as I approached them to handle them in unique ways aside from the conventionally accepted methods. I was awarded a sizable financial bonus for one project as management was amazed with its innovativeness and how it did not disturb the workplace employees . . . where the approach was something never seen before by company management, nor by the coordinated outside vendor.

[@The_Lincoln_Penny]

I really wish people would stop saying that Penske used a “loophole” or found a way to “bend the rules”. I know it gets headlines to say that. But if you really think about it, Penske was under the exact same rules as EVERYBODY ELSE in 1994. The rulebook specifically allowed two distinct engine formulas to be used .... a “purebred”, overhead cam engine and a “stockblock” pushrod engine (with larger displacement of 209ci and more boost). The conventional wisdom was that the pushrod engine would never be able to be successful in a race (look at all of the Buick stock blocks that grenaded ).Just because the “conventional wisdom” used by the majority of teams that year was to use the “purebred ” doesn’t mean that Penske “bypassed” the rule book. All of the other teams had the EXACT same opportunity and chose not use it. PS 1. The engine had a single turbo, not twins 2. Penske did not have to convince ILMOR to take the project .... he was one of the owners 3. There was NO ... NO .... Mercedes Benz money involved in the project (read the excellent book by Jade Gurss titled “The Beast). It was all Penske money and he went to MB late in the project and offered them a “gift” of branding the engine (There were some big $$$$ benefits post-race as a result the “gift”. Mercedes would eventually acquire Detroit Diesel from Penske Corp for a very substantial sum). 3. The engine was not ever banned. USAC lowered the allowed boost levels immediately after the race. 4. Mercedes didn’t know the engine would be banned. In fact ILMOR had built blocks (valued in the millions ) in anticipation of large orders for 1995 stockblock engines. Then USAC unexpectedly lowered the boost levels again making the engine ineffective and turning those blocks into large paperweights.

Despite all this, it's undeniable that they made the better engine and won - Only to have their engine (effectively) banned from the competition. "Lowering the boost level to make it uncompetitive" is no different than telling them flat out they weren't allowed to use it. Rules or no rules, I still think it's a shitty decision on the part of the race organizers to put restrictions on what is supposed to be incredibly advanced engineering and racing. Telling me I can't use 4 wheel steering and high boost pressure to go faster is such a stupid tactic of allowing otherwise useless teams a chance at winning. Personally, I believe that if a company finds it worthy to dump millions of dollars into a specific engine, then there should be no stopping them.

[@jamesdeen8158]

@Peters6221 That's not my point - The fact is that they still changed the regulations to make this no longer a useful design.

[@andyharman3022]

There is a whole book about it by Jade Gurss, titled The Beast. He even posted in the comments below. And there is a couple of pages about it in Karl Ludvigsen's book "Classic Racing Engines." The engine made 1040 Hp at 9800 rpm according to Ludvigsen's book. The big trick that they pulled in the design of the valvetrain was the use of oscillating cam followers instead of the typical reciprocating followers. The engine's combustion chamber design was unique being sort of a Hemi with a rotated valve set.

Sounds suspiciously like a chevy indy engine smokey yunick built for indy. Same 209ci, also pushrod 2v but with twin turbo not a single turbo. Allegedly in one configuration it made 1300hp but it was before the days of electronic fuel injection and of course it had fueling issues so maybe didn't make as much of a splash as penske and mecedes. a similar rule was exploited by BMW in f1 who took a 1.5l i4 and turboed it up to 1400hp using a stock block rule. Sanctioning bodies should allow whatever mythical engine a team decides to build but regulate the air scoop and providing a restrictor plate. Sure you can have a 500ci v8 with a tunnel ram and 180degree headers... But you have to suck all your air through a straw! Power Specific air consumption doesn't really change much from engine to engine, the best teams would only be a few percent above in hp. The best way to cheat with a restrictor plate is to manipulate the incoming air so it forms a vena contracta in the right spot. If the sanctioning body wants to take it a step further they could use a venturi instead of a plate so the teams couldn't manipulate it too much.. No need for rules to be overly specific.

[@PistonAvatarGuy]

@@danieldimitri6133 I don't think that F1 had a rule requiring that a stock block be used, as Honda (who was dominating at the time) had a purpose-built V6 that was making around 1,400 hp. Also, BMW wasn't making 1,400 hp, 1,280 is what is claimed by the engine builders.

I believe this is an example of “gaming the rules.” What they needed was a general rule that could have removed the victory ad hoc, what is called in some rulebooks “failure to do right.”

[@MikeSmith-pq4wz]

I love when human ingenuity finds the loopholes in the rule book and and out-smarts those who wrote it. Rules placed on NASCAR to make all the cars basicly cookie cutter cars for all the drivers has ruined NASCAR. Personally, I would like it to go back to Stock car racing like in the 60's and 70's where the best driver in the fastest car took home the trophy or made love to the retaining wall trying to win.

[@Roy-ji7bg]

That's why I cannot watch Nascar anymore they've got 700 800 horsepower or more engines out there and restricting them with restrictor plates which I personally think they use to help people win that they want to win could be wrong the weather is Big Money there's cheating

Nothing "stock" about this stock block. Not even derived from a stock production engine.

[@rod928s4]

your information is incorrect,Tony...camshaft was located in the block as per regulations and a further change was made to allow pure race engines with cam-in-block as well for 1994. Read the Jade Gurss book "The Beast", its quite incredible!!

[@tonyradca1235]

@@rod928s4 If you follow the letter of the rule yes, but that was never the rules intent. This engine failed the smell test when it comes to the spirit of the rule. Plus unlike the Buick engine, the Mercedes was never sold in a production car in any form. Hence the name "stock block".

[@DennisMerwood-xk8wp]

@@tonyradca1235 Exactly right Tony! Of all the comments on this blog you are the only one to get it right! The Ilmor engine was a pure racing engine with a special bespoke block. In complete violation of the the intent of the rules. Menard's Buick V6 was based on a block in Buick family car as USAC intended. The Ilmor should have never been allowed to tun. It was only Penske's bribing and leaning on the rules committee that permitted the engine to be run in the race. Thank you.

[@rod928s4]

Gentlemen, I must respectfully disagree. Please remember that the rules allowed more displacement and boost for stock-block-based, 2-valve engines and this was still not helping Buick engines even though this rule was to help them specifically.The reg was changed specifically to encourage more variety and participation from other engine manufacturers but USAC did not expect llmor to build another type of engine.

[@tensecondbuickgn]

Buick's Turbo V6 pushrod engine (later Menard V6) was killing the field in time trials in the years prior. Too bad it suffered reliability issues. It's my understanding that there are still track records held by that engine

[@MegaScott]

Exactly how did they reduce Friction by shortening the Pushrods? Generally a pushrod engine needs a specific pushrod length to keep the geometry of the rocker arm correct, thus minimising side loading on the Valve. This is no secret, this is how it has always been done.

[@ragimundvonwallat8961]

the rocker arm geometry can be fixed...but massive piston friction to the cylinder wall due to agressive rod angle is not fixeable, the same for a very poor rod to stroke ration wich give a very sudden accelleration to the piston as the engibe rev

[@DeMZIrus]

Exactly my thouth after watching this video. Penske had a good engine. OK.

[@Al3xisAE]

They probably did the testing. They wouldn’t be able to teach Illmore or Mercedes much about engines

[@hannesgroesslinger]

In a very simplified way: There were basically 2 different engine regulations. On the one hand there were the "normal" racing engines that were used in all the races over the whole season. On the other hand there were the "stock block" engines which were only allowed at Indy. The idea here was that an engine manufacturer could build an engine that was derived from a road car engine block, which would make it a lot cheaper. In order to make these engines competitive they were allowed to have higher boost pressure. Penske figured out that the "stock block" rules did not actually specificly say the engine block had to be from a road car. It just had several regulations about engine configurations that would not normally apply to racing engines, like the pushrod configuration for example. Of course thats a massive simplification of what actually happened. But basically Ilmor built a bespoke racing engine that was perfectly designed for the stock block rules. Since it was a bespoke engine it had an advantage over the real stock blocks, and thanks to the higher boost pressure it had an advantage over the other bespoke engines.

They did 228 mph in 1990s and alosno in a mclaren did 227 mph . How would you expect to qualify for race?

[@weallfollowmanutd]

Those cars were faster back in 1994. Far less regulations. Those engines had 1000hp, or more for the Mercedes. The average speed per lap now is 230mph for P1 position at the Indy 500. They have around 700hp these days.

[@hannesgroesslinger]

Today the best cars do 230 mph average, with 240 mph top speed at the end of the straights. That Penske in '94 did 228 mph average, but with 255 mph top speed. That tells us some things about the difference in handling and corner speed...

[@weallfollowmanutd]

@@hannesgroesslinger I agree, which is why the average speeds are so close. Don't forget the tire technology these days has gone up several notches.

[@georgfriedrichhandel4390]

It must also be said that Penske Racing was not very competitive from 1995-1999 when it had lost much of its edge. After dominating the 1994 CART season with 12 wins out of 16 races, the won five races in 1995, no races the following year, three races in 1997 and then they went winless until 2000 when they won five races again and the following year they joined the rival IRL and the rest is history. During the latter half of the 90s, it looked as if Penske's dominance of open-wheel racing had ended.

[@csmith9684]

'He did say by candlelight...?

[@christophercripps7639]

I seem to recall that Penske owned (owns) Michigan intl Speedway. Always nice to have ones own oval for secret testing. USAC probably didn't think anyone would spend millions to develop an engine for one race. But Penske did. Just like in the late 60s Porsche built 25 "production" 5 liter sports cars to compete against 3 liter prototypes after FIA reduced the number needed for a production model from 50 to 25. That Porsche was the gr8 917 model. Indy 500 Penske Racing a model of excellence; endurance racing, Porsche often out front at 24 Hrs Le Mans.

[@X8X8X8X8X8X8X8X8X8X]

​@@jamesstewart1794 There is nothing "Mercedes" about this engine, it was developed by Ilmor for Penske. A similar deal was done with GM years before when the Ilmor engine was labelled "Chevrolet" until 1993. Pesnke offered Mercedes the naming rights to the Ilmor engine in exchange for investments in his companies, including the purchase of Detroit Diesel. Over the years, Mercedes bought increasing shares of Ilmor which produce the "Mercedes" F1 engines since 1995. Since then, the company has been renamed but still bears no technological connection to Mercedes itself. A part of the company split off and operates under the Ilmor name, having built Honda Indy engines until 2011 and building Chevrolet (!) Indy engines since 2012.

Someone should make a new Racing series called F0 0 car restrictions of course for safety all cars are driven remotely on closed courses. The goal get the fastest lap time possible. Just as in rally the team with the fastest lap time wins. Unlimited power unlimited Aero dynamics 0 restrictions. Let's truly test the boundaries of what is possible and push technology and engineering to its maximum extreme. With drivers in simulators and spectators far away from the action drivers they don't have to worry about dying or killing someone in a crash so they can push the car to its limit. Of course you will have drivers pushing beyond the limit which will end in some very spectacular crashes.

The only involvement that MB had was the choice of the font for the “i500” engine badge. Mercedes did not have any other involvement. Penske and ILMOR offered MB the branding rights late in the project as a gift. that “gift” had huge benefits for Penske and MB post-race. Like the billion dollar deal where MB purchased Detroit Diesel from Penske. And Penske started using mostly Freightliner trucks (a Daimler brand) in his rental/lease fleet. The book “The Beast” details MB”s involvement
