weight versus power

[BeetleBug]

Its a combination between the engine hp and the gearbox

Indeed, you can`t have one without the other.

 

Actually, the trans is not really required, but you wouldn't get far without an engine.

Are you going to weld your engine in place behind there?

Direct drive baby. 10 mph @ 6000 rpms.

haha,

Well i found out the hard way when i build my first 1914 engine and broke the diff

[nicolas]

hmm weight is a big issue, but i think i am not talking about thenths but more seconds... 

they ran times between high 14's and mid to high 15's. i on the other hand have had a best off 16.79. so we are talking a full two seconds that i am slower; and i refuse to take blame myself for that 

Well... if you stop during your run to connect your throttle cable you will be loosing some valuable seconds.   

Or refit the airfilters  Looks like I am already beating you then dude as I have had a 16.02 at Santa pod 

I can't wait for next season - should be fun 

hmmm, i still have a chance at beating you if you do all the work on the engine yourself then. 

no seriously, it will be hard to get half a second off this time with 115 HP and a 1000kg car. Kalle can you calculate my ET with this? i would like to know what margain i am looking at here. thanks a lot.

Hi Nicolas,

Rear wheel hp or flywheel hp?

If rear wheel; 16.03 and 136 km/h
If flywheel; (115-8%) 16.47 and 132 km/h

OK - so let`s tune your engine;

150hp; 14.62 and 148 km/h
180hp; 13.81 and 156 km/h
200hp; 13.33 and 163 km/h

Or you lighten your car and have 115 rearwheel hp;

950 kg; 15.76 and 138 km/h
900 kg; 15.48 and 141 km/h
850 kg; 15.16 and 143 km/h

And last but not least - you get the race fever after SCC 2009;

850 kg and 220hp; 12.21 and 176 km/h

If rear wheel; 16.03 and 136 km/h

so with 170hp and 13.63 and 160km/h what did my old car weigh?

hmmm the last option is the one i really like 

so i got 0,3 seconds between my time and the calculated best ET. as i have 115 on the flywheel and can't remove the fan. going on a diet is a good option, but letting Jeff drive (12kg) might be better. maybe Storm (2kg 500grams) could opperate the pedals...

otherwise it will be very hard to achieve better times. i was wondering what that beautifull golden squarback with black roof had for engine? it was very fast and i liked it a lot at SCC.

many many thanks allready.

That squareback you`re refering to belongs to my friend Jørn Tangen. And yes, it is indeed a beatiful car. You can see more of his car here; http://www.vwnorge.no/index.php/topic,2705.0.html Only Norwegian but you do get the point from the pictures. This car is really heavy with water pipes, radiator, sound killer, full interior + + All you want from a true street car. And it is fast - very fast; 12.20 and 185 km/h using ordinary street tires.

He took it to a dyno day event recently and dynoed 343hp and 506nm.

PS; Storm is now 9kg and growing.

Damn what are you feeding that dog? deer? moose?

thanks for the link and you know i understand Norwegian  it is a very cool project, but a 66 in VW blue would have been awsome as well. i have a 67 and the more i look at that car the more i like the colour. from hate to love really. a very cool project and maybe in the future i can chat with the guy.

Strictly dog food and he is a bit skinny - good growing conditions here you know. Good luck with your project(s)
