Ohlins FSAE Dampers

[Mr2fastna]

All,

Do to the amount of interest we (Ohlins) have gotten lately about Dampers for the FSAE we have decided to put together some packages for university purchase. Please note that while our prices may be higher then what many teams are used to there is a good reason that we have more championships than any other damper manufacture. Also as an alum of FSAE I understand that in the past few years the cars have progressed to a point that quality dampers are a huge asset to most teams. On to the shocks.

First we have our budget offering of our 36mono damper that can be built with an eye-to-eye of 10"� and a 3"� stroke or spaced all the way down to 8.5"� with a 1.5"� stroke. These dampers can take either a, 1.875 or 2"� spring. The FSAE price is $290 and the damper is not externally adjustable, though it is user re-valvable.

Next, would be our ST44 damper. This is a 2-way externally adjustable shock with a piggyback reservoir, though we could also do a remote hose reservoir. The eye-to-eye is 10.85"� with a 2.76"� stroke and it can also be spaced to 9.67"� with a 1.57"� stroke. It can take either a 2"� or a 2.25"� spring. Pricing will be $490. This is a true racecar damper and is very easy to revalve.

Third, we have a short version of the standard ST44 with all of the same feature as above with a 9.58"� eye-to-eye and a 1.70"� stroke. Prices for FSAE teams will be $570.

Finally for teams that hold up 7-11's we can put you on the same equipment that we use in CART and the IRL, maybe even the Audi R8's if it's a big 7-11.

Please contact me directly for more information.

Very nice!

Its nice to see that suppliers are somewhat catering to FSAE needs.

We tried, 7-11 only has $30 on hand after dark.

[jack]

the ST44 is a pretty cool damper, thats great that your offering it on the cheap.

too late for this year, but i will deffinatley consider ohlins next year. (probably not the ST44, though http://fsae.com/groupee_common/emoticons/icon_wink.gif)

[Ben Beacock]

scott: could you post the mass for each those dampers? if not, can you fire me an email with the masses http://fsae.com/groupee_common/emoticons/icon_wink.gif bbeacock@uoguelph.ca

Ben

[Mr2fastna]

Ben, the weight of the ST44 is about 40oz and the 36mono is about 30oz. Also for any team that wants to make the trip to Indy we can do a quick damper clinic with some damper theory and go over re-valving our products, just call ahead. So what do you have in mind Jack?...

[Matthew Robinson]

290 per shock or per 4 shocks?

[IsheeM]

Scott,
I think it would be nice to schedule a shock clinic around PRI as I know several teams send a few members each year. I know I will be there.

Thanks,

[Mr2fastna]

Michael, we will be having 3 free seminars during the PRI show (one each day). I invite all teams to come and bombard us with questions.

Matt, all prices are per damper. http://fsae.com/groupee_common/emoticons/icon_wink.gif

Also to keep from answering some of the same questions twice, all of our dampers come valved to your (or our( or my, I have tire data, no you cant have it)) spec, there is no standard valving.

[95M3Racer]

I was helping a Stohr CSR at Limerock on saturday, and the Ohlins on it were spectacular. Highly recommend them...now if we could only afford them http://fsae.com/groupee_common/emoticons/icon_wink.gif

[Mr2fastna]

Thanks for the plug m3racer, you check is in the mail http://fsae.com/groupee_common/emoticons/icon_biggrin.gif. $290 for anything with the Ohlins logo on it is a steal. Along those same lines the actual retail price for the 36mono is $290, so you dont have to worrie about it blowing your whole cost report. The damper is built just for FSAE so no one will find any other price for it. Also, The mono-balls in the 36 take a 10mm bolt so you might have to turn out some spacers, I know most of you do this anyway.

Update: I've been doing some research today and I think we could do the 36 with a piggy back and one external compression adjuster for $400 to try to find some middle ground between the 36 mono and the ST44. Retail Prices for your cost report will be 36m-$300, 36p-$400, and ST44-$570.

Now if only we could get those deals on our personal street/auto-x cars. I assume the single adjuster on the 36 your talking about is rebound.

[Mr2fastna]

Actually its compression.

Scott

[Cement Legs]

And I assume when you say that the price is for each damper that springs are 'not' included?

Cheers

[Mr2fastna]

That is correct.

[Juan Andres]

Are you offering these shocks for 2006?

[Mr2fastna]

2005/2006 Update:

We will only be offering the ST44 dampers to teams this year as getting parts to build up the others have been near imposable, plus the ST44 is a much better damper to work with. Call for pricing but please understand I'm am only in the office 2 days a week this time of year and may be very hard to reach. The standard size will be 272mm eye to eye with a 67mm stroke. The damper can be spaced down to smaller sizes but doing so also directly effects the stroke, i.e. 270=65, 260=55, and so on. They will also only be offered in a hose mounted canister to make packaging easier for teams. The best time of year to get dampers would be during the late fall, early wintertime. If you wait till spring you will be SOL! Hope everyone had a great summer.

Hi Scott,

Ford GT brakes = junk.

[Mr2fastna]

Rob,

Glad to hear that project went well...

[TG]

Scott,

will anyone from Ohlins be at Phoenix International Raceway or Firebird Raceway anytime soon?

[Mr2fastna]

I will be at Phoenix for the Grand-Am race.

What day? PIR is offering us tickets to all of the days. I know I'm definately going on Thursday and Saturday, maybe Friday... don't know. I know a bunch of the other guys are taking advantage of this, too.

[95M3Racer]

I've been workking with Ohlins NA, and their other main distributor(other then mosotsportspares) to develop dampers forBMW race cars and now street cars.

I've also just discussed developing the ttx40 for a radical and some sports racer applications.

Ohlins are the best shocks available in my opinion...all they need is a marketing department, only place they are majorly lacking.

[Mr2fastna]

95M3RACER, I know, someone keeps calling me and asking what I did to the Turner cars and that they want to copy it.

TG, Thursday through Sunday.

What about the Cane Creek shocks that I believe based on the ST44?

http://www.canecreek.com/46.html

[CMURacing - Prometheus]

the link you posted says ttx40. and i'd buy them and equip them for our '06 car if not for price...damn.

[Mr2fastna]

The Crane Creek damper shares a tiny bit of technology with the TT44's, not much but a bit. They don't have anything in common with the TTX's other than the use of two tubes. The Double Barrel was designed by one of our Swedish engineers who happens to be a bike freak and is probably the best mountain bike damper made thus far. They are still very much a displacement sensitive damper designed for long stroke low frequency use and would provide very little hi-frequency short stroke control, like a race car needs. Like most mountain bike dampers the biggest problems is the slow (relative) damping force build-up and the excess amount of inherent hysteresis in the system. On another note I've finally been talked into doing some real SAE papers on dampers as there are very few correct ones floating about and many with bad information. So hopefully these will help FSAE teams select qualities that are important in a damper and selecting proper damping curves for their cars.

Cheers,

Scott

[Bentley58]

Interesting stuff. What design features contribute to a damper being displacement sensitive?

I want to investigate this more on some dampers. I was thinking of exciting a damper on a dyno to see how quickly it builds up the force seen at a certain velocity. This should also give you the hystersis in the damper. I wonder if I could put a shock and spring combo on the dyno and see what the spring lateral deflection does to the friction. I'm curious to see what shock internal design features allow a shock to build the desired force rapidly and so forth.
