What are some things I can add on to my car for better acceleration? I don't really know much about cars, or what all helps what

 

I hate D17. period. hahaha

 

crower stage 1 cam no tuning just drop in go from 95whp to 125 whp

 

Swap in a k series.

 

Is this verified from firsthand experience, or a guesstimation? I guess it doesn't really matter either way since the OP "don't really know much about cars" and swapping cams would likely be more than they can chew.

 

verified with dyno graphs just not on this forum

and Butt dyno'ed by a number of people CuriousG is rocking one right now it is a pretty nice upgrade

 

why do you doubt my Author-i-ty LMAO

 

I know you've had your hands dirty once or twice Paul, it's just that 30whp from a cam and absolutely nothing else seems a bit generous. That's all.

 

hahaha I know it seems like a lot but it's a pretty nice boost in power I helped george install his bryan had one that he got dyno'ed and with k-pro it feels even more powerful.

the cam perfectly offsets the stupid amount of fuel the stock ecu dumps for no reason and it works great and it makes your bolt on's seem more alive and for the increase in power and the ease for these cars it is almost a no brainier unless you are shooting big

 

Wow thats impressive, those cams are for vtec heads only right?

 

yep

 

can you please elaborate on this

 

the stock ecu dumps a lot of fuel a lot more than it needs to. could not stand my car when I had a stock ecu in it. it would dump so much fuel that it would smell like gas all the time. dumped so much gas that it actually clogged my cat. and it is not just my car every stock 01-05 civic that I have come across you can smell it when it starts up that it is dumping way too much fuel.

if your car is tuned right and setup you should not be able to smell anything with or without the cat.

but what the cam is doing since you don't have control over the fuel is it uses the larger lobes on the cam to open the valves up further and longer allowing more air into the combustion chamber and it evens out with the fuel that the ecu is telling the injectors to dump. so you end up with a better burn which will give you more power and it uses that excessive fuel that the car is already dumping and a lot of the guys that are running this cam have said they have also seen an improvement in gas mileage.

this is also one of the reasons you see an improvement in gas milage and power right of the bat with k-pro you can lean the mixture out cause stock if you put a wideband in you can see it is running a lot richer than it should.




edit: oh and part of the reason the stock ecu dumps so much fuel is cause in order for the cat to function properly it needs an extra amount of fuel to create the chemical reaction in it. this is part of the problem with emissions with a really good tuner you can make the car run stoich almost the entire time leaving your actual emission off put almost at zero the car will be better for the environment get better gas mileage and make more power. but the oil industry and the U.S. govt have different ideas. Ever wonder why the old insight that averaged 75 miles (and could be hyper mileaged to 100+ mpg) to the gallon never last more than a couple of years and the new one only gets like 40 something miles to the gallon at most.

 

You for forgot to mention w I/H/E.

 

I've never smelled gas when i start my car up.

 

so ur sayn stage 1 cam, k-pro, and tune you will see this kind of power? also including i/h/e??

 

no I am saying stage 1 cam and you will see this power there is no reason to tune for the stage 1 cam. the cam was already designed around the stock ecu



so NO TUNING
and I think bryan had the cat still on the car when he dyno'ed and he was running a really restrictive exhaust last I remembered


to other post have you walked around to the back of the car or been standing by the exhaust cause almost all of the stock ones I have dealt with dropped an exorbitant amount of fuel

 

Dollar for dollar the best mods you can make are a free flow intake system (hi-flow filter, larger throttle body, etc.) to replace the stock airbox, coupled with a performance exhaust system (header, hi-flow muffler, larger pipe). You should always try to do these two together. Remember, an engine is basically a pump. The less restrictive the intake and exhaust systems are, the lower the amount of energy it uses just moving air/fuel mixture, resulting in more "useable" power.

 

I do all the time

 

dollar for dollar the best mod you can do is the stage 1 cam or nitrous why don't you leave this one to the guys that actually know what works on these motors and keep the theory in the class room

 

How much did you get your cam for? Should I upgrade my cam gear as well, if I want to buy the stage 1 cam?

 

thats pretty nice numbers just for swapping the cam. so what if one were to build the head(valves, springs, etc.) and run the stage 2 cam and a k-pro tune. any idea on numbers? has anyone done this.

 

^^^^ agree thats pretty impresive for a d17

 

So you can't run this cam in an A1?

 

i know that the d17s are pretty hard to get na power out of. Im really curious about building the head(like i said pnp, valves, springs, etc) and running the stage 2 na cam and gettin a tune with k-pro. if anybody has done this please let me know if there were any good results. or if it was an epic failure.
