How hard is it to get more hp?

One thing ive alwayts wondered ever since i got into street racing was how hard is it to make a slow car fast? And how expensive it is. so if you would add something that might help answer my question.

That's a pretty vague question, you are gonna need to be more specific than that...

ok, well then what would i need to make some thing into like a 12 sec car, would i need more than like cold air intake and turbo or would i need some spray?

you can get into the 12s easy with a turbo, not using nitrous, you just gotta find the right car/engine setup to do it with...hell you can get into the 12's with a foxbody mustang 5.0 if you know the right mods to put on it.
Edit: and is it cheap to get a foxbody 5.0 into the 12s?...let me put it this way...it's aeons cheaper than trying to get a maxima into the 12s.

To make some thing into a 12 sec car? What kind of question is that? Could you be more vague?


For an Enzo you would have to add a parachute and for a tercel you would have to pour thousands upon thousands of dollars.

I understand im being vague... sorry. ok how hard would it be for the cars in my profile?( mitubishi evo Vlll, subaru wrx, toyota celica, toyota mr2 spyder, toyota supra, Mazda Mx-5 miata)

evo? basic bolt on stuff, hell some can do it stock
WRX? reflash the ecu to put out more boost, then basic bolt ons like cat back exhaust, turbo down pipe, maybe a bigger intercooler
Celica? jesus, lots
MR2 spyder? you mean the new ones? lots as well
Supra TT? hardly anything
Mustang? Already answered that question, but it takes less than a celica, and more that a twin turbo supra.

That's what i thought for the celica 'cause hp is low and doesnt have turbo.

$4,000 will put a 99+ GT mustang into the low 12s. Foxbodys can run 12s for $1,000 if you know how to do your own work.

My car needs DR's to get into the 12's.

DR's?

DR's?
Drag Radials.

whoops

you know speed demon... i noticed your picture of the naked vehicle. it's off topic i know, but i was thinking "if i was him, i'd look at that and go "what the hell do i do next?" cause that looks so confusing and so very depressing, i would never be able to strip a car that much down...

well those cars are alot easier, because it still uses the old style body on frame chassis. they're very weak against twisting though. modern style cars that are light to middle weight and even really modern heavy weigh full size cars uses a unibody. i think unibody is waaay better. however if we strip our cars down, it will very be a naked rolling chassis like that. you would still see the passenger cage, with the roof, and the engine bay.

Its as hard as getting more air in and out of the engine, getting the right amount of fuel into the CC with that air, compressing it more, having a more complete combustion sequence, igniting the Air/Fuel mixture at the exact right time, lightening everything and anything, improving driver skill, getting power to the ground or traction, and being able to control this new found forward motion.

But to answer your first question, generally every 1lb/min of airflow is equal to 10hp. So to get more HP, you must get more air in and out of the engine along with the right amount of fuel and ignited at the right time. Its not rocket science, but it is. Same basic principles of accelerated particles applying force to an object thus making it move and turning that movement into work. Its energy converted to work. You are basically harnessing something powerful enough to destroy your engine and having it power your engine. Don't you think the right amount of supplies and punctuality are important?

Luckily companies have made parts that do most of this for us. But a simple saying can simplify what is to come.

Speed is all a quesion of how much you want to spend.

Never really thought of it that way but makes TONS of since
