Sort of IKEYA formula shifters (google it), but more tight!
Then again, it's not for everybody :P
The mechanical maps for the 6 speeds F40 Saab gearbox are just now being developed. It won't be long to the first try-out.
Will keep you posted, anyway!
updates?

Gmalma Hi Lucian and everybody else! Just a short debut. My name is Zoltan and I have a Maptun stage 6+ biopower 9-3 and I am from Hungary. (not far from you Lucian ) I also would like to develop the weakest point of our car,the chassis and brakes to. Of course I am using powerflex bushes and lower springs with Koni adjustable shocks and I have 8pot D2 racing brake with 330mm disk..ect, but all these things not enough to get the car in best shape. After many years searching,now I found this thread about the Sellholm control arm,which sounds great! I am asking you Lucian and everybody else who uses this control arm,is it so good how looks and sounds? I already spent lots of money on the car,but this part is very sensitive for the car and I do not want to spend more money,if this product is simply not amazing! Waiting for your experiences and recommendations. Thanks!

bogan Have you tried the shifter out yet?

Does it work?

Only the movement of the shifter lever is up-down, instead of the H-pattern. The gearbox internals, even the shifting bows are the stock ones. The translation from linear to H-pattern movement is done by the machanical maps on the lower side of the shiftet assembly.

aeroauto Do you have a working shifter in the car? I'd like to see a video if you have one.


Oh yeah, will be available for purchase???

seq shifter kit

thought to post a preview of the seq shifter kit...all, including display for the current gear
I am quite anxious...

bogan Hooray, he is back !

I like your shifter

sequential shifter FTW

Also, I will roll the dices and try to modify the gears shifter from the H pattern to sequential: push the lever straight forward clank-clank-clank: 1-2-3, pull it to downshift.
Feel free to chime in on this
One step closer in developing a shifter that converts the H-pattern to sequential

i think you have to search the td04 hybrids. i see them make 360bhp on pump gas. uk saabs has great info on these.

your going off ancient data where t28 is better than td04 housing not anymore maybe 2008 not 2011. people swap internals from td05 housing into td04 making a td04 flow damn close to td05. which is better than the .49a/r t28. the 6cm stock unmodded is around .42a/r if you clip it you can get .49a/r+ off td04 6cm. the 7cm is 50a/r and its still td04. clipped wheel with 7cm housig and youll have even more exhaust flow which is more hp at the cost of shifting power up in rpm.

i can agree the t25/t28 has a bigger a/r than a unmoded tdo4 5cm and 6cm but not the 7cm or clipped 6cm. but im comparing the best td04 to the best t28 so clipping and other things are involved.

and im sure the compressor wheels on mhi are lighter than t25/28 and they are bigger. not positive tho
To be fair, I have never contended that NO TD04 framed turbo could outflow the T28. Just that the typical SAAB TD04 19t with a 6CM housing couldn't. As I said before, I stand by that.

As far as taking a TD04 to the max like you are suggesting, the cost becomes comparable to Garrett GT series turbos so it's seems a moot point to me.

mike9000aero I believe power numbers aside that a td04 is a better investment then a t25 as you said mike they are worthless. I have seen countless cars with 150+ miles on them with a td04 most t25 are long dead by 100k. In 4a years working on Saab's I've replaced three td04 and I can't even count how many t25's. That's one reason I lime the td04 though I don't know for sure what Turbo is most capable power wise.
Seems each side to this has a good argument. I mean as to what mike d says most 19t setups are running 300+ to the wheels and it seems to me that if your running the Turbo where its safe then both turbos run about the same power output.. I know as david has said his car is at its limits with its hardware.

I'm not trying to say which is better but from everything I have read generally speaking they both run around the same peak power when on a modest tune. Which Turbo Can make more area under the curve I don't think has been proven for sure. But it does seem as though Davids car has the best dyno graph out of the two with the most peak.
