What kind of top speed would, say, an 88-91 ITA Civic/CRX see in the 1/4 mile?

Have any of you IT CRXen drivers actually run the 1/4?

Scott, researching.

 

Do I smell a 2005 Challenge car?

14.5 - 15 seconds, would be my guess.

 

<90mph i guesh?

10 ... with NaWS.

 

isn't there a known calculation for this sorta thing?

 

Ahem. WRONG forum. Go back to the "we don't need a stinking steering wheel" forum.

Stop wasting our time.

 

Naws. 2 of the big ones. Talk to harry.... he can hook it up overnight from Japan.

If you are not granny shiftin and double clutchin, you'll have a 10 second car.

But if you even lose by an inch, you lost and you never had your car and you're definately not a real racer.

 

I'd guess 14.5 at 91 ish.

 

Funny you should ask...Larry Webster has a write up of what it takes to build an ITA CRX in the spring issue of <u>Car and Driver's Boost</u>.

http://www.caranddriver.com/boost

Here's a rundown of the test results (car has a 4.71 FD):

0-30: 2.7sec
0-60: 7.1sec
0-100: 21.0
1/4mi: 15.6 @ 89mph

If any of you would like, I have a PDF of the article. I just haven't posted it due to copyright concerns.

 

No 1/4 miles here, mang. Stock final drive or what a real ITA CRX should have?

 

My guess was "about 90mph."
So I'll give myself a prize later.

Thats a powerful nose you got up there. You can smell that? Even over the smells of New Jersey?

Scott, who already has everything but the chassis.

Get some thin mints and set the Paula Abul collection on "repeat"

I believe a former ARRC winner, the #60 OPM car, ran a 15.3 @ 92 (or 93) mph in the 1/4 at Atlanta dragway (Commerce) on dirt stockers a few years ago. This is with an lsd and a 4.7 FD if I'm not mistaken. I think that's pretty impressive.

 

I'm not sure how much faster an IT preped motor will be but my sts civic ran a 15.9 at commerce. That strip is supposed to be a good 3 tenths or so slower than most. I just added some lighter wheels and a crank pulley so hopefully I'll be going back when I get some time to see if it got any faster.

 

bolt some slicks on the lude and you will see 12s...

As someone who has worked the Challange the last 2 years... if you want to do well, you better at least be in the 12s at the strip. The points system is biased towards the drag race rather than the autocross.

That's a lot of NAWZ starting from ~15...

 

i will bet money scott's car will not see 14's with a tail wind.....try 15 mid to high....maybe low....

Not really trying to win. More of an exercise in seeing if I can build a fun autocross car out of spares and junk lying around from the ITC car with a few ebay purchases peppered in here and there.

It appears that actually winning that event takes far more manhours and fabrication ability than what I have to work with. But I think I can put together something respectable. IF I can find a chassis that is somewhere in the neighborhood of *free.*
I have to claim a reasonable value for the stuff I already have, which shouldn't take me over budget, but I can't really spend much on the chassis.

11th motor?

 

My CRX, set up with basic bolt ons for CSP ran a 15.0 at 90 mph. That of course is with a stock FD.

 

These cars were high 15's in the high 80's stock, so I'm suprised thay ain't that much faster all race-riced up. Might have something to do with tire choice, despite short gears and a slip.

 

Actually, they were low 16 stock. 16.3 was about the average. It did not take much to get them into the 15's though.

My 15.0 was before I had a LSD though. I am betting the car now is capable of a high 14.

 

Going back to the article, they've nicely listed test results from back in '88 as well.

Again, I've got the article if anyone wants to see it.

 

Well, I based my reference timewise from the 86 Civic Si's I've had, both which ran 16.2-3's at 83-84. Weighed around 1950-1975. 91hp. A next gen CRX Si, with a little more power, but not much more weight should have been just a little bit faster both in time and trap speed.
