For those that think you have to have a big block to make big power
I was riding my jet ski this weekend and it occurred to me....
My lil' ol' Seadoo has 1.5L (about 91 cubes) and makes 250 horsepower. Not bad....for an engine with less displacement than a 2liter of soda. It's not an apples/oranges comparison...... The PWC engines are water cooled and intercooled (so they can run more compression and more boost) and it revs to 8200 rpms....but still. |
1972 porsche 917-30. 5.4L, 1500hp @ 39psi.

http://www.youtube.com/watch?v=o_QyUD6V5_I Nothing like trumping your Champ Car with a little F1 power, the first time I was at the US GP...I thought my ears were going to bleed. I'm still in aw with 19000+ RPM shifts. |
:D
Our Cosworth F-1 Engine qualified at 21,000 RPM in 2006 in the Williams car. I believe it was the highest revving four stroke engine ever in F-1. An F-1 engine does utilize pnuematic valve springs though... Since I know the HP numbers from both the V-10's and V-8's in F-1 I can say the Champ Car engine made more power! The F-1's did however; make upwords of 1,500 HP in the late 80's with their Turbo engines. They wouldn't last much longer than a qualifiying session though.... Also forgot to add the the $ comment.... Add a zero to the Champ Car engine cost above and you'll have F-1 costs. |

I call bull on your daughters GN. I had one, and stock, they ran 13.90 in the 1/4. porsches and lambos don't run sub 10's out of the box. Check your stats again bud. |
Curtt Scott runs cobracountry.com he sells a DVD called "bitten by the snake" It is getting kind of old but it is still a great Cobra DVD. They talk to several cobra owners with "alternative power plants" A Dodge V10 and a Buick GN V6.

There's no doubt there are some low usage/race applications with wicked hp/volume ratios.
I was speaking more along the lines of viable "everyday" or high usage applications. My jet ski is supposed to last for a few hundred hours of operation. As for some of the other stuff, it's truly amazing just how much technology has advanced and just what some people can do with small engines. As a side note, the GN is one of the top 10 "tuner" cars of all time. It ranks up there with the 03 Mustang SVT Cobra and the SRT-4. All are cars you can drive off the lot, and with a small amount of cash and some minor modifications, you can surprise any number of folks with fully built street cars. |
