F1 engine technology

"Take a look at the intake ports in post #62. There's no way you can match the efficiency of those with a production-based engine."

This is the best I've found to date, SHO V6 Yamaha piece.

Gotta say doesn´t impress me yet...
A Yamaha designed 5-valve head you can see the tops of the pistons when the valves are open.
Yes I had a Superbike with that engine...

That 917-30 was an umbelievable car. It weighed 1800 and change. The engine set to endurance-racing boost was 1200 hp. He could dial up the wastegate from the cockpit and get 1500+ out of it. Which he did if he had trouble getting past someone. He won every race in '73. Since canAm was set up basically to be a no-rules class, they imposed fuel consumption rules in '74 so that everyone else wouldn't give up and go home.

A Friend and a good friends dad and Icon to me raced the last Interseries race with a 917-30 Martini car after he run out of money in F1 as an own team and lapped everybody and put some serious hurt on his competitors...

Well he had won the series 3 times in a row 71-73 so didn´t come as a surprise and did the 1970 season for John Wyer in a Gulf Porsche 917K with a mexican...
Tried to save the mexicans life 1971 from a burning Ferrari 512S at Norisring but could only watch his former teammate burn in the seat from a few yards...

the 917´s...whatta program I still have original receipts and stuff of one of the teams involved in the development.

The former team owner and the driver both live less than 20 miles from me and all the crew members.

By the way, Emerson Fittipaldi ran one of our cars up to 252 mph with the 1994 pushrod engine. On the track at Indy without a 3-mile run-up.

Chuck, I know I could look it up, but in the interest of keeping the conversation up, didn't DeFerran set some sort of speed record in one of your cars at Cal Speedway in 1998ish?

And not to kissass, but Pat, man you've always go the coolest photos! Keep 'em coming bud!

Well I´ve had a better flowing head in my hands and I´m not talking about ladies..

from a production based engine but they are multivalved...

Are we talking pushrods only or production engines in general ?

Enter Honda...

I was referring to any 2-valve pushrod engine. Multivalve engines are inherently better: more breathing area.

Dude - Yes. Gil ran 240+ for the lap at California Speedway, a much faster track than Indy (and on far better tires than we had in 1994...). That (final) version of the turbocharged CART Honda engine was right at 1,000 hp, but it made the power by turning 15,000 rpm.

The impressive thing about Emmo's 252 trap speed is that he came off of Turn 2 at less than 220, and gained 30+ mph in about 6 seconds.

I could transmit 1000hp through my pencil if I could turn it fast enough... but that 1000hp wouldn't get a boat on the plane

You just need to call Pat and get him to make a transmission for your pencil... Then it'll plane. :sifone:

I finally took the Museum track tour at Indy last year. Chuck, I know that you're all too familiar with how narrow that track is, but for any of the guys on here who've never been there, all I can say is Holy Sh*t is that place a death trap. The guys who run that fast at that place have nuts the size of grapefruit. Standing on the track made the hair on my neck stand on end...

We had our xmas party last night and the Big man, Mario Illien, came over to party with us! Its cool to hang with him.

I was there 1984 and IMO it´s not that narrow compared to other tracks around the world. True deathtraps are Targa Florio, Nurburgring, Monza, Imola etc etc...

Did he share any stories of his days as a tank commander in the Swiss Army?

 

[shifter]

Dude, I am glad you like them.

We used the same engine in a supercar in 1989 also......One off the second one had a Judd v10.

We can always use an Offy for old time sake. This one ran 258 at bonneville.:sifone: 1500hp......:sifone:

Only a few more weeks 'til Bahrain! I'm excited to see how the new teams will fall into place. Hopefully they'll let the Serbian team on the grid.

Has anyone been catching the DTM,BTCC and Aussie V8 Supercars on the Speed Channel?
