95 civic drag race car project
 

So after many tries to stay competitive with all the faster car, I started to look at what I may be doing wrong.

Horse power was about the same at others and im not a bad driver either.

So my 2000 honda civic that I been racing the last 5-6 years, I decided to put it aside for now and get a 95 civic h/b.

The new car came with cage and race ready, but I want to take it a step further and make it more aerodynamic so hopefully I can get ahead of the competition.

I looked in the drag coefficient and compared the two cars to see how much power it looses at different speeds. The best I could get my 2000 civic is as low CD as the 95 civic.

Cant' post pics yet, so I have to wait until after the next few posts.

Taken in consideration the cars CD and frontal area I made a graph of how much hp a car looses at different mph.

Next step and thats where hopefully everyone here comes in, is to help me decide what mods are the best improving CD in the 95 civic.

Front bumper block off
Rear kammback
Under body full flat panels

Here is what I been testing on my homemade wind tunnel.

Does the car have a smooth belly pan? That would be a very important upgrade to make. You could even secure it with hood pins or something for easy removal.

Just how fast is this car? I noticed the ITB's sticking out of the hood so im guessing its pretty well built.

Car is built, motor makes about 350 whp all motor. In the 2000 civic I ran a 10.7 sec 1/4 mile @ 126 mph. All other cars are running about 130 mph.

Car will have a belly pan all the way, working of the right angle and length of the kamm back. Also thinking of a scoop above the itb's so it will get air from in front of the bumper where there is more air pressure.

Damn, nice work on the sub 11 sec.

Kammback here ya go :)

from the pic it looks like you got some interior you can still remove. and remover the door glass and replace it with the netting. also what class are you running in so i can look up those rules....

I would also get that front end lower or go get some type of chin spoiler put on like some garden edging.

The way they are now the TBs look like they are in the low pressure area.
