realistic performance

[foamypirate]

our hondas are pretty aerodynamic. i have my turbo cb doing 130 and didnt feel it.

130mph is a FAR cry from 180mph. The co-efficient of drag goes up with the square of your speed, basically. It takes a great deal more power to do 180 than it does to do 130. Hell, my stock F22A1 auto Accord did 118mph easy. That same car is NOT going to do 180. Ever.

CBs are also not even close to being "pretty aerodynamic."

I never said I'd did 180. I did 130 in fifth and shut down. I wasn't trying to go real fast. I could of done 140-150 easy, 155 is pushing it. My next setup imma try to do 160+

btw I meant ek, sry not good with civics

Everyone should be able to do 180 in their cars.... my a1 stock could do that....

180kph that is.... or about 112mph.

Realistically, an h22 swap in an accord, I would guestimate that your top speed be around 145-150. To do 155 in the Bugatti Veyron needs a pettling 270hp. To reach its top speed of 253mph, it needs another 730hp.

The Drag coefficient of a cb7 is actually pretty on par with ferrari's and Vipers of the same era.

The biggest problem is as you increase speed it takes more power to move from 145-150 then it did to go from 135-140. The power needed to get up to 200 mph withing a reasonable distance for our vehicle wieght is substantially higher than a lightly modded' h22.

wow, I didn't think I would get so many replies. The top speed thing is cool, but I never see a need for ever going over 100, and that would be on the interstate and late to a wedding.

I was more interested in 0-60 and mpg. Whereas few members have the time or place to top out there cars it would be simple for anyone to find and empty road and floor ti with a stop watch. Actually that is one of the things I intend to do after I complete my swap.

[cloudasc]

0-60 in an h22 accord? 7 seconds or less. My a1 converted a6, does 0-60 in less then 9 seconds, and thats on an auto without preloading the suspension, and the iabs always open. Video is in MRT. As for MPG on the h swap? Better then the F22, probably about 2-4mpg more for both city/highway compared to an F22. Thats mainly due to the higher compression = higher efficiency = it takes less to do more.

[Zmatt]

I hope it gets better than 9 seconds. My manual says that My LX did 0-60 in 9 seconds new. With prelude engine I was hoping for more like 6. I mean the H22 gives you more torque and horsepower and less weight than a new si and it does 0-60 in 6.3 seconds.

Maybe somebody will tak a CB and build the hell out of it and take it to the salt flats. I want to but don't have the money nor knowledge on what has to be done to be safe to go 180+. My goal in life is to be in 200mph club.

I'm being realistic with my numbers, there are also alot of different factors that affect the performance of the vehicle. Driver weight & ambient air temperature, how much gas is in the tank, auto or manual, the size & weight of the rims & tires, and the list goes on.

My 86-88 15" Legend Alloys are lighter then the 14" Steelies for example. Also your source that claims our cars new are 0-60 in 9 seconds most likely doesn't list the test conditions which makes their claim hard to precisely compare with (and they usually use do the tests in "optimal" conditions)

If you want to find out the answer your either going to have to find out at your own expense, do some research, or just keep asking around, eventually someone will be able to provide the information your looking for.

Dude u smoke the finest rocks made. I got 88 legend alloys, bafuckinlieve me they are no where near lighter than steelies

[93F22A6]

Even if they are lighter it's more of where the mass of the wheel is. Weight matter but where it's at in the wheel does to.

Well I'm saving for the engine swap. I plan on doing it next June. So I'll find out sooner or later. As for the numbers they came from my manual. I don't know what Honda did to get 9 seconds 0-60 but that's the official numbers.

Just by looking at the specs an H22 swap cb7 should do close to 6 seconds 0-60 considering the specs in the current civic si. The K20 has no torque compared to the H22 and the cb7 weighs a bit less, not to mention the slight Hp advantage the H22 has.

At any rate when I get mine swapped one of the things I intend to do is get some solid numbers on performance. I think it would be valuable to the cb7 community if the owners knew what they could expect form certain upgrades.

ok.

i did ask this question once.

something along the lines of "how fast should my car be" i believe was the thread title.

i got what i thought was about correct ET"s.

most were saying mid fifteens based on my setup and estimated power.

at the track i was running an h22a with an intake and lsd auto trans, stock ecu no tune.

my 1/4 was 15.63@90mph

not fast by any means but 2 secs better than a stock cb and well with in the range of estimated times for my setup.

With a 5spd and a tune you could be in the low to mid 14s. Or at least that the usual range for the H swap.

im so aware of this its killing me.

i bought the car with the current drivetrain. and i have a p28 ready to chip n tune.

as soon as the proper 5spd comes my way im jumpin on it.

nor-cal folks be aware!!
i need 5speed!!!
