hello.. how can a car such as trick and manswetto's capri do 1/4's in the 7 something without being blown and you have door slammers not much quicker with blowers..
im having a blonde moment but any discussion is welcome as i am on my L's with engine stuff.. why not put trick and manswetto's engine in a door slammer and add a supercharger for 4 second passes? cheers.. |

when you're talking about 7's, there's 10's of thousands of dollars between fractions of a second. i don't know the car you're talking about, but i'd say that has something to do with it and N/A vs blown.

http://www.youtube.com/watch?v=TMiob2p0xng And an in car vid when it was running 7.9's in late 2007 http://www.youtube.com/watch?v=QVj4y...eature=related Same run from the passenger seat http://www.youtube.com/watch?v=gjev7...eature=related It doesn't really work like that. There are so many different engine configurations in the various drag-racing categories and the block, heads, induction, chassis set-up, etc etc is an artform in itself to piece together. The T&M Capri big-block is around the 1100 horsepower mark from memory and that motor probably cost upward of $70,000 to bolt together plus endless development time. Running mid sevens at around 190mph. Doorslammers and T/A run high and mid fives from 230 - 260 mph at 2500 - 3000 hp. Top Fuel (T/F) run down to mid fours at 330 mph and to do this need 5000 hp with engines costing into the multi-hundreds of thousands $. You have to put down a lot of power (torque) by the 60 foot mark to run those times and speeds and a Pro Street/ Pro Stock engine will never do that. In those top 2 or 3 Group 1 categories it costs something like $100,000 in development to chase a tenth of a second improvement. Last edited by Eleanor; 05-04-2009 at 04:29 AM. |

just to give you something else to think about - the fastest human being can run 400m in just under 44 sec. he has less than 1hp to do it(and hes alot quieter).

Different classes of cars have to conform to different sets of rules which in some cases can appear to hinder some performance these cars are capable of

law of diminishing returns - make a slow car 1 second faster costs less than $1000 with nos. To make a 6sec car run 0.1 sec faster will cost $100,000

trick and manswetto's capri is one of the fastest "street cars"

The law of diminishing returns.
Also traction probably plays a big part of it. Having a lot less power the T&M Capri can put its power down a lot easier than a doorslammer will with more than double or triple the power. A doorslammer would be a fair bit quicker again if it could put 100% of its power down the whole length of the track. With the multi stage clutches they use it may only be getting its full power down well after half track i'd imagine, but someone who understands it better may be able to explain it better than I can. |

A top fuel dragster has 8000hp and does 4.4 second 1/4. to go 4.3 you need 9000hp

lots of cubes, strong driveline and chassis.
Or lots of cubes (still) and boost. 8 second cars aren't fluffing about. a bit OT Does anyone know if some of the faster 10in tyred cars (i think there is even a class for untubbed cars that are pushing into the 9's and/or 8's) allowed chassis connectors? they'd have to or they wouldn't run straight.. Didn't nugget's old XA twist?
