This and more is certainly possible. I have heard of several street and strip Hondas that can rev over 12K with a properly build engine. I believe F1s are now over 19k rpm from similar displacement. The hardest part will be balancing street drive-ability and top speed capability.
Great aero and big boost and enough money, could reach this goal.
Good luck.

Get a Hayabusa and be done with it.

I have a friend with a speed3. I have driven the car quite a lot. I've even tracked it myself. You have loads of torque, be excited about that. Getting the car to breath above 5500 rpm is what you need to make higher speeds possible, but you'll end up losing that crazy torque the car has. Work on the aero as much as you can as you will see many benefits from it.

I have told my friend about this site within the last two months and he has now gotten the aero bug himself. For guys like us we can imagine making it just that much more fun beating on big motor cars in our turbos, especially our retarded looking aero mods at times. Makes it that much better when we reveal the fuel economy we are receiving. So good luck with your venture. One major issue I am always worried about it keeping my motor at an optimal temperature but creating less open space on the front of the car.

I am intrigued and I promise not to be a hater.

Not necessarily one over.
Some of us like to have our cake (FE) and eat it (fuel) too !!

While Basjoos would never condone such actions, his aerocivic will still pull good track numbers. Remember his goal is 100MPG @ 80 MPH. Its top speed is well over 100MPH and he still gets better FE at those speeds than half the cars in the garage do at 60MPH.

Eco doesn't mean only crawling to 55 MPH !!!

Do you have a fuel log? Even if it's a secondary goal, I'd be curious to see how certain mods initially intended for performance have effects on efficiency too.

Aerocivic - Honda Civic modifications for maximum gas mileage - aerocivic.com

he gets better gas mileage at 90 mph then 90% of the cars on the road get at 60 mph. Also a calculated top speed of 140 mph with 102 hp. That is damn impressive in both areas. -GW

Wow, stopped getting email notifications about updates to the thread; didn't realize so many posts had popped up since the last time I checked.

For those that are interested, I will be building a transmission *AFTER* the motor is built and tuned so I can perfectly match the ratios to the output of the motor.

I'm currently looking at going the EFR route from BorgWarner, and have roughly plotted out an engine on their Matchbot to see what I could hit; the link is below:

( Edit: post count not high enough for links; see attached image )

Obviously, ambient temps in the 100 and high altitude are not good for high speed anything; however when the time comes to run the Texas Mile, power will be over 500 horsepower according to Matchbot (assuming 70 ambient and local elevation of 200 feet).

As for the fuel log, I'll see about getting one today when I go into town to pick up fluids for the next set of mods to happen either this weekend or next. With that all in mind, sometime next month I'll likely start ordering bends for the full on custom 3" vband exhaust (with manifold) I'll be building to replace the restrictive stock parts.

Stay tuned!

I thought the same as you did when I first found this site, hence my name....


How crazy are you willing to go on modifying your car's appearance?

Lowering the roof, and tapering it down towards the back should help with the aero if you are willing/able to do so.

I'll have to get seats before I can even think about lowering the roof line; as it stands, there isn't any clearance for a helmet on my fat head. Tapering is already done on a stock car as it is; see the screenshot in the first post.
