for example to Ford 460 was mid 300's in 1970 (D0VE) and dropped to 200 a couple years later But on the bright side we don’t die of asphyxiation when stuck in traffic. Lol. |
Yep. When I built the 440 six pack for my Super Bee, the carbs had mechanical choke and I wouldn’t drill the firewall to run the cable. That lead to the 10 min ritual of starting, keeping motor running while sitting in car. Purred like a kitten once warm but didn’t like being woken up 😉 |
BigSilverCat. I agree. 1.6-1.65 attainable on 93. Very reasonable.... pretty funny about some other claims...when we lowered rpm to 7000rpm reliability went up mainly due to stabizing valvetrain issues..Never really had a bottom end failure. |
Love those numbers.
Being a 2 stroke O/B guy I regularly hear that we need to turn a Hyabusa (etc) motor on end and we'd have something. My reply is always the same. Stop your Busa at a light, base of a hill, put a fat passenger on back, jamb it in 6th gear, let the clutch out then call me ;) Before they banned the 500cc 2 strokes (20 yrs ago) from motorcycle road racing they were making 200 HP's or 6.66 per cu in. But thats w/a multi speed gear box. 800 HP's from 509's, @ 7K pushing that big of boat..........for that long........, wow! Thats impressive. I cant even wrap my head around a valve train staying together at that limit. I read that the Pro Stock car guys run titanium valve springs (approx 1400 HPs, 500 cu in @ 12K), only material that lasts. I think I also read, $1500 per set and last a weekend. How heavy is your class and how long (75 miles??) is the average race?? I am a huge fan of the "Engine Masters Challenge" that one of the car mags has done for yrs. They set rules on cu in, compression, heads, octane, etc then let teams build their answer to those parameters then put it on a dyno. They average #'s based on RPM targets per the rules. The rules change each yr. I love seeing some of the ideas the teams come up with/try.

Our Super cat engines are 509 cuin and in theory make 800 HP (unless your NZ-1, AMH, WHM, performance, ect. there's probably make 2000 hp) So around 1.6 hp per cuin but that is on 93 octane fuel and ours lived a whole season of testing and running.
I do have a 2 stroke that makes close to 6 hp cuin n/a and a rotary that makes close to 7 hp cuin. And a diesel that makes 4 hp cuin but on lots of boost. |

Interesting. And yeah, F-1 is in another world. Too bad they’re freagin hybrids now. Frankly, it is unreal - none of us could run our engines WFO for 100 straight hours, under the stress they are put under with no issues..... |
Eric, my son Dylan and I try to catch the F1 races every weekend when he's not at his mom's. He's a diehard Scuderia Ferrar fan... Vettel is his absolute favorite driver, period, though he's pretty interested in Leclerc. The cars are incredible! And personally, I love the sound.
|
Hey Tom.. Hope you're doing well! That's cool your son is a fan (even though he roots for the enemy)!! Leclerc is a special talent and I genuinely like him.... Going to be a star of the Future. |

The wife's car is 2009 Gen 4 viper, For the 2008 Dodge Viper, the engine's output was increased to 600 bhp (608 PS; 447 kW) @ 6100 rpm and 560 lb⋅ft (759 N⋅m) @ 5000 rpm of torque via a slight displacement increase to 8,382 cc (8.4 L; 511.5 cu in) and the use of variable valve timing, among the first utilized in a pushrod engine. The bore was now 4.055 in (103.0 mm), If you have ever been a Gen 4 or Gen 5, you can attest to the CRAZY amount of torque the engine puts down, the torque is just incredible, and it's N/A all the way baby! |
Watching Brazil qualifying now. I prefer engines over electric motors but I get it. Give me a 24,000 rpm V-10 any day 😎 I wish they would let us see them though. I miss the old crew too. Steve Matchet used to show some of mfg processes for some of the parts. Mind boggling! I want to see those engines! Even the header work is jaw dropping. I could spend hrs watching old YouTube videos. Cars on track, Sennas magical qualifying lap at Monaco , and engines on dynos. They have dynos that simulate tracks, corners and gear shifts. Incredible. The engine playing “God Save the Queen” is a favorite. Dean, I had a dock mate that had one. He owned several rockets including my favorite of a turbo Carrera. I asked his favorite and it was the Viper. Said they were all great cars but you had to be in the right gear for them to be fun. Said the Vioer had so much grunt it didn’t matter which gear you were in. |
