SWR ST180 Development complete

Postby SteveWyndhamRacing » Fri Aug 15, 2008 3:46 pm

Hi Everyone
Image

After 2 year of development of the Fiesta ST180 performance kit we have finally got there.

Sorry for the long wait guys, but development takes time.

Exhaust:

We started development of the Fiesta ST in 2006 with our race car which we ran in the SA production car championship. In those days we had to run pretty much a standard engine, only exhaust were free so we began playing with different performance exhaust manifolds. I first tried local manifolds but was not entirely happy with the results, and then decided to import a Miltek 4-2-1 manifold (which was expensive over R6000.00, but good quality and finish) which worked quite well. I was still not entirely happy. After trying lots of different options we have now come up with a 4-2-1 racing exhaust manifold which gives plenty power and torque from as low as 2000RPM all the way up to 7000RPM. It also fits in without having to drop engine and loosen gear box mounts etc.

Camshafts:

I also tried importing different camshafts (long and costly process, cams in and out of engine and dyno tuning) We have now come up with a SWR performance camshaft which works really well from 5000RPM up to 7000RPM and more, without losing any bottom and mid range power.

Mapping:

We used the Dastek Unichip Q.
I have been using Dastek Unichips on all our race and road cars since the early 90's without any problems whatsoever. Dastek Unichips are sold in almost every country around the world. Like any of the reprogrammable ECU's, it has to be mapped properly, giving the right amount of fuel and ignition timing that the engine requires. Also very important to map the engine at different throttle positions throughout the rev range, which take a lot of time, but this gives you very good throttle response and driveability. One must also remember that if you change any component eg. Induction, cams, exhaust etc the vehicle has to be remapped to get optimum performance and economy. I have tried all the different ECU's, Heltech, Motech etc which are all good. It depends on the person that is doing the tuning. We have some very good tuners in South Africa, and some not so good!!! :D With our performance kits one does not need to touch the mapping!!

Note: If i bring out any new mods, performance upgrades etc then i will make sure that i have Dastek Unichip exchange units mapped to optimize performance. Customers can send there Unichips ECU's and i will send them a replacement (ready mapped for a small fee +/- R200.00 plus postage costs)

Dyno Work:

We used Kosie Swanepoel's Dyno which is very conservative and accurate. Kosie and myself have come along way together (racing etc) and he does a great job!! Thanks Kosie..!!!

Induction:

We have fitted a K&N induction Kit which works well (good quality, tried and tested, used by many tuners world wide) they do proper development on there products before launching to the market.) I feel that there is more to be gained on the induction side and will be testing various diameters and lengths on the dyno in the near future.

Our aim was to develop a performance kit that is:
- AFFORDABLE
- IMPROVED ECONOMY WITH NORMAL DRIVING
- IDLE SMOOTHLY WITH AIR CON SWITCHED ON
- VEHICLE TO ACCELERATE FROM 0-100KMH IN UNDER 7 SECONDS AT THE COAST!
- IMPROVED LOW DOWN POWER AND TORQUE(+6kw/+30nm at 2500rpm)
- IMPROVED MID RANGE POWER AND TORQUE(+25kw/+45nm at 5500rpm)
- GIVE PLENTY OF EXTRA POWER AND TORQUE BETWEEN 5000RPM
AND STANDARD LIMITER AT 7000RPM (+34kw/+50nm at 6500rpm)

(NB: No need to rev higher than this as when changing to next gear, power and torque is still max at +/- 5300RPM.
(Revs shorten the life span of an engine!!)


We are extremely happy with the results!! We plan to come up to Joburg to visit you guys and to make sure the fuel and timing maps are perfect at altitude. I have ordered 40 sets of SWR performance cams, they are being manufactured in Europe at the moment, still waiting to get confirmation of when they will be shipped to me. I might fly a few sets in specially for those that cant wait.!! We have a waiting list of 37 customers wanting our SWR ST180 performance Kit.

Thanks to Mike97 For his patience and use of his car!!

Hopefully this will give you guys all the info you need!

Regards

Steve

Very nice, well done SWR.

KSD dyno is a very stingy load dyno. It is the lowest reading dyno in the cape period. For reference all the other dyno places I've been, KSD reads at least 8% under, thus 134kw would translate to 146kW on the other dynos'.

BTW, my RunX RSi was 134kw at KSD as well, between 144 and 146kw at other dynos'.

The Torque falls off quick, need some induction, exhaust improvement. Bigger intake manifold would help (new design) and 60+mm exhaust too. With some wave tuning one can extend the peak further up the rev range and gain some more power.

Nice cars at the garage. Is that one of the 4rotor Mazda's that were banned from competing?

Hi Abrahamr
Thanks !You are right Kosie's dyno is accurate,that is why i use his dyno.I don't want to be advertising power figures that are'nt true!!You are right it is a 4 rotor mazda that ran at Le MANS!
Sounds like your Runx is quite strong!
regards

Hi Steve

Would love to hear that Mazda in all its glory. Is the car permanent in SA and is there some event happening soon?
Coincidence that the Fiesta ST is based on the Mazda MZR engine.
Do Steve still have the Falcon XR8 race car? I like my V8s, busy with my Sierra XR8's 302ci engine. Ran a bearing or 8.

RunX is my everyday car, only has a decat, big enough for a family, light on fuel and a hooligan after 6000rpm.
Torque is only 180Nm @6900rpm, wish there were more. 218NM would be nice.
