scannon Posted February 14, 2007 Share Posted February 14, 2007 I've been a horsepower junkie all my life. I've been fortunate to drive some very powerful cars on the track and I always want more. Like slngsht, I love to put my foot down and feel the Gs. Skip Link to comment Share on other sites More sharing options...
yellowss7 Posted February 14, 2007 Share Posted February 14, 2007 Speaking of G's, in a couple of autox's last season, my codriver and I found ourselves out of breath at the end of a 55 second run. We're still trying to figure out why? Was it the g's from the hard cornering/braking/accelaration? or were we just holding our breath to brace ourselves against the pull of the harnesses? I like to think it was the G's http://www.usa7s.com/aspnetforum/images/emoticons/ack2.gifhttp://www.usa7s.com/aspnetforum/images/emoticons/biggrin5.gif Tom Link to comment Share on other sites More sharing options...
slngsht Posted February 14, 2007 Share Posted February 14, 2007 Maybe it's because you let all the air out of your lungs to save weight on the run http://www.usa7s.com/aspnetforum/images/emoticons/rofl.gif Link to comment Share on other sites More sharing options...

spotcheck Posted February 15, 2007 Author Share Posted February 15, 2007 I was only trying to reply to the new guy's inquiry as to what to look for in a seven. Just didn't want to scare him off if he didn't go big I didn't mean I was scared off of the power requirements for an LSIS - the thought of a 600 HP Se7en strapped to my a** was scary. Some years ago, travelling in New Zealand, I met a former astronaut on his way to set up a radio telescope in Antarctica. In response to one of my quesitons, he said "Sitting on top of that rocket on the launch pad, there are no atheists". 600 HP sounds kind of the same.

andrew7 Posted February 15, 2007 Share Posted February 15, 2007 The rally in July should help you make a good choice because of the diversity. If I were to buy one it would be a used Caterham or a Westfield from Flyin Miata. To build a street legal Locost from the ground up becomes very difficult. There are many unforseen problems that must be solved and you start wishing it was finished already so you can start driving it. With that said, I own a BEC 7 Locost, approx. 1050lbs and 175hp. I'm still not sure what to think of all these web racers http://www.usa7s.com/aspnetforum/images/emoticons/smile5.gif The following is from The Magnificent 7 book. The Caterham JPE was developed with the help of EX-F1 racer Dr. Jonathan Palmer and then-current McLaren F1 test driver. It held the world record 0-60mph in 3.46sec. and 0-100-0 in 12.6sec - over 3 sec faster than a Ferrari F40.(These records have been beaten in the last couple of years by the Ultima GTR.) Palmer commented, "It's the nearest thing to a Formula 1 car on the road." The car weighs 1168lbs. and has only 250 hp. My opinion is any 7 with 150-250hp will be very fast for the road. Anything over 300hp save for the track. The only exception is Mazda with his Cobra in Sevens clothing http://www.usa7s.com/aspnetforum/images/emoticons/biggrin5.gif .

scannon Posted February 16, 2007 Share Posted February 16, 2007 Or 300 or 400. http://www.usa7s.com/aspnetforum/images/emoticons/hurray.gif Too much HP is just barely adequate! HP is like a drug, the more you use it, the more you need to keep the buzz going. I lust for a power to weight ratio of 3 lb/HP which means about 430 HP for my SV. I'll likely never see it but 4 lb/HP is doable. My first iteration will be around 5.4 lb/hp. I'm hoping that level will sustain my habit for a year or two, then another engine will be built and more boost applied. My Miata has 8.6 lb/hp and to me it feels slow. I take people for rides on the track and they are often overwhelmed by the acceleration, not to mention the cornering and braking. Skip Link to comment Share on other sites More sharing options...
slngsht Posted February 16, 2007 Share Posted February 16, 2007 I have to agree with that. When I got my C5, I said to myself "self, this is a fast car... you'll be happy for a long time." Then I added some more grip, and realized it's not much fun when you can't light 'em up on demand. So I bought the Rotus, and added power. I'm at 4.31 lbs/hp including driver weight. I'm about to add some major traction. Hope it doesn't become boring because the LSx engine family can do up to 600hp N/A, and more with forced induction http://www.usa7s.com/aspnetforum/images/emoticons/lol.gifslngsht2007-02-16 10:53:35 Link to comment Share on other sites More sharing options...
locostv8 Posted February 27, 2007 Share Posted February 27, 2007 Or 500+ Too much hp is almost enough. I'm shooting for 4.6 lb/hp with Put-Put to be followed shortly after with Shagnasty at 2.8 lb/hp or slightly better.locostv82007-02-26 23:55:34 Link to comment Share on other sites More sharing options...
