Ross Tuffbond Cas Replacement ?

Recommended Posts

A friend is putting one on his 2530 at the moment.

What we have found is the hall sensor when fitted with the supplied bracket fouls on the teeth on the balancer so we had to space the sensor down. (not ideal)

The supplied power steer pump pulley wont fit on the pump shaft 1mm to tight and it wont line up with the belt, we have tried Rb30,26 and 25 brackets.

The 26 one lines up but the shaft on the pump is splined not smooth like the 25 one.

Calling Ross or whoever now runs the company today to see why we have these issues.

I can assure these things work, it was designed on our car by Unigroup Engineering and Ross. I will admit that we only run the bottom half as its a 26 in an S14 and the CAS Sensor Ross designed wont fit in our car as its simply too bulky

We had around 500rpm worth of incorreect singnals in the upper rpm range and this fixed it straight away. It works a charm with the Link G4 that we run in the car.

I got one on my car as Ross has sponsored it to me. I can back them up they work a treat car now runs and tunes much smoother. More accurate at the higher rpm rev ranges around 10000+rpm, the car is punching out approx. 1200HP no dramas at all. I am running dual triggers one on Crankshaft and Camshaft with a Vipec V88 ECU, so far so good, I have only used it for one drag meet so far which was Brisbane Jamboree. So I haven't had much time to properly test it. But I did notice a fair few GTR's at WTAC where running these setup's so they must be doing something right.

I have a few graphs below taken off my own car.

Ross trigger kit. That's using the 34 - 2 timing wheel.

Wow, huge difference. Surely that would have to aid longevity to remove the torsional vibrations that would cause.

What is the whole kit worth? Anyone know if you can buy just the sensors and sensor wheel? As in upgrade an existing Ross balancer.

I got the balancer trigger wheel sensor and braket and convertor box to change the signal to Nissan for $2000, and didn't use the box as I changed the computer to one that reads directly off the sensor, I believe the balancer that has the trigger wheel is different to the normal/older style one, google trigger wheel rb26 there are heaps of different setups avalible, I'm currently looking for a 24-1 tooth wheel to replace the 36-2

Please write down ross's finding or yours. sound not so good by your review :(

Dont get me wrong, I know the system works. It just isnt fitting.

Ross have sent an adaptor for the power steering issue, should get here by the end of the week.

would this work with a haltech without the expensive 600$ blackbox? At this point, my car is well-moded.. I just want to make it run smoother/safer etc.

Indeed it will. If you have a Pro Plugin go with the 12 tooth crank wheel. No converter box required.

Yeah E11 will decode almost any trigger setup, as will the Platinum Sport range.

As the Pro Plugins are designed as a plug and play application, they were locked to the standard trigger on the designated vehicle unless you requested specific firmware from Haltech. 24+1 is now a user selectable option across almost all Pro Plugin ECU's where the trigger type is a popular modification for that vehicle.

Here's the option as found in the R34 GTT Pro Plugin setup screen....

Ross upgraded our balancer when they designed the kit so i believe it should be a simple upgrade. It was a current balancer and was yet to be fitted to the engine though so dont know if this changes things

I guess you would need to call Ross and ask if they are all able to be upgraded

Piggaz, that really does show how reliable and rock solid it can be. It makes a big difference to timing values when your signals are a lot cleaner and makes it that much safer to make decent power ;)
