Hi we are rebuilding our SR8 2600 Gen 1 engine and would like to see if anyone can assist with-
Cylinder orientation
Firing order
Cam timing specs
@jwb Hi Josh, I've converted my SR8 to a MoTeC M150 ECU. I can help with that information. Facing forward, the cylinders are numbered 1-4 on the left side starting at the back (nearest the gearbox) and 5-8 on the right. Firing order is NOT what Radical have published. I've got that too, but I'll have to look it up within the MoTeC config. Cam timing specs is stock, AFAIK. A Suzuki shop should be able to provide that.
@parsonsj Hi thanks very much - I just found a previous post of yours listing thus information
I appreciate the help
@jwb I'd give Schnitz Racing a call. If they don't know the specs, they will probably know someone who does. Schnitz Racing - Contact Us
@jwb Firing order from my MoTeC config: 1 fires at 0*, 2 at 180*, 3 at 540*, 4 at 360*, 5 at 288*, 6 at 468*, 7 at 108*, and 8 at 648*. The SR8 engine is a 72* banked V8, which is why the right side seems odd. Firing order is 1-7-2-5-4-6-3-8. It uses a single plane crank, so the engine can be thought of as two 4 cylinders joined by a common crank with 1-2-4-3, and 5-6-8-7 firing orders on the respective banks (though the right bank is shifted by one cylinder to a 7-5-6-8 as part of joining the V8).
Hope this is useful. I spent several weeks verifying this and getting it to work with the MoTeC!
