I am very interested in the ATS final and I was curious if anyone had installed or used it for an Auto-X/ Road racing applications (not streeting the car) if you would, please let me know if it is too aggresive or if it will balance out a setup?

Is there anyone out there with an opinion, or are you just not giving me opinions because I am newer than most

 

It's because you haven't bothered searching......

Your search for ATS final drive returned 101 results.

 

I searched, thanks for the help

they were all in archives.....I just wanted some recent opinions

 

bump..........for any useful comments

 

I know this doesn't address the original question, but I daily drive on an ats 4.9 FD and coming from the 4.4 FD it's just KRAZY.

I will be road racing/ auto-x-ing a little later down the road. It's like when your in 4th just rev's hella fast and bam when you hit 5th gear you'll still be in Vtec, so vtec doesn't fall off.

+ here you go, this is an interesting thread. go down a lil and read about the road racing w/ the final drive

cool cool thanks for the tips, I have heard great things about it....

 

Good for road racing/auto x/ canyons etc.. Not so good for 1/4 mile racing.

How so? Why wouldn't it be beneficial for quarter mile racing? I don't c that.

edit: A 4.9 fd would have a more consistent advantage over a stock fd in a 1/4 mile. Am I right here?

Cool thanks

This threw me off I guess, maybe I'm misinterpreting

This is why the stock FD can be a big advantage on tracks where you spend a lot of time near redline, but the shorter FD can be a big advantage on tracks where you don't. So theoretically, if you were on a track where you spent the entire track driving between 79 and 88 mph, or between 88 and 104 mph, you would have a clear cut winner between the two gearing setups. However, most tracks have enough of a mix of speeds that you're probably going to be spending some time in the same gear, and some time in the higher gear, and the gains in one set of stretches will largely offset the losses in others.

For example, tom91ita mentioned Grattan, and driving most of the track (in his 1st gen CRX) in third with the longer (stock?) FD, but spending some time in fourth with the shorter FD. That's a typical scenario. On the stretches where you are in third gear with either setup, the shorter FD is quicker. On the stretches where the shorter FD forces you into fourth gear, the stock FD is quicker.

FWIW, in my ITR, I find that I can do a lot of Grattan in second gear - including the off-camber turn 3, the fast-turning stretch from the braking zone after the jump to turn 7, and the toilet bowl. On those stretches, a shorter FD will require the use of third gear in those turns, and possibly fourth gear elsewhere, and it would be a disadvantage in those areas. In the areas where you would be in third gear in either setup, it would be an advantage.

Incidentally, on a dragstrip, the shorter FD is more consistently an advantage, because of the large amount of time you would be in first gear, and in second gear, with either setup. In our ITR example, from 0 to 55 mph, the shorter FD is a significant advantage most of the time; however, above 55 mph (where you spend road course time) the advantage swaps back and forth between the two setups, depending on the road speed.

nice write up......glad to know the majority of the people using this FD for road racing/Auto X are very pleased with there results

 

for autox, it's imperative.

for daily, it's fun.

for road racing, it depends on the track.

for drag, calculate your mph and power first - then decide.

i've run the 4.9 in two of my project cars and will be installing it in another one soon.

Everything ATS is

You will get a lot of "do a search" responses wrt the 4.9 or ATS type of questions - simply because the subject has been (quite frankly) beaten to a bloody pulp type of death..... Lots of valuable information is in the archives - regardless of whether it's recent or not, it still holds true..... Try the FAQ in the itr forum - the is a buttload of final drive links.
