380-440 ish depending on setup regards what you said above mark,but you will have low down torque so with short shifting might be more power available to use
Once I have rods car I will be able to comment how well that is putting down 700+ hp, from the videos I've seen though it looks like it needs to be caught just right or its wiggling it's bum alot lol
MarkV8. Not sure how well the Cosworth drive train will marry up to a 5litre V8. Rod's Cosworth seemed to be ok handling the huge power it had , maybe it's new owner will be able to let you know what was done to it's drive train to cope?
Will be aftermarket management, but it's a V8 engine so more low down power.
Do any of the after market systems tap into the ABS sensors (without buggering up the ABS) ?
It really depends how sensitive the ABS system is. Some will dislike any tampering, only way to find out really is to try..
Being an older system, it might be a little less fussy than some modern stuff though, or you can get VR to digital converters that really shouldnt appear any different to the ABS system that say a multimeter or scope hooked up so again, probably shouldnt pose a problem.
As for how much is usable...depends how you want to use it lol. I'd like to think that on a good dry day with good tyres etc, 4-500hp should be quite reasonable
Also interested in knowing people's thoughts and opinions, I unfortunately never got to do many miles in the three sapphires I had. Currently on the hunt for another for an engine conversion.

I've got a very similar set up, just with a different gearbox that might need an uprated input shaft as it's only rated to 450 ft lbs.
Don't know if the tyres will give up grip before the gearbox lets go though!
Hard to say....and think it'd struggle to get as low as 500hp, so it's never really been used at that level hard as such, other than a few short instances running it n/a.
But that would only have been a few straight line runs rather than anything else. Although when it was like that, it sounded bloody class, and did seem to grip very well.
But mine would also be near 1/2 ton heaver than most Sierras which doesnt help matters.
Despite the inadequacies etc I've used it at hillclimbs here which are road events and whilst it will never be superb, it's surprisingly usable, although being stupid I've never run it fully at as low boost as possible which would undoubtedly make it safer and maybe even faster lol. Just maybe not as much fun.
But the traction control on the Syvecs is very good, although I'd see it more as a safety addition than a real performance enhancer. Although I guess they're both sort of interlinked.
Really though...the last thing in my mind is making less power, I'm happy to tootle about most of the time on the road anyway, and most road surfaces here are crap for grip anyway.
Just let it make whatever power it makes, and enjoy it.
A clip from one in 2017. Didnt really do any last year. You can hear the traction control here. It's a good clip....but totally unintended ! Damn thing locked the diff up when I changed down coming into the bend and started to slide ! Around 1:15
With all your bits it should put its power down well but you may well need to phase the power in in the lower gears to help traction.

I assume I will need DBW throttle and switches to know what gear it's in?
Gearbox is T56 if that makes a difference.
Guy I'm in conversation with on engine spec said it should have 500 ft lbs by 3000 rpm naturally aspirated

Gear can be calculated from vehicle/driven speed and rpm, both of which the ecu should know. If your T56 already has a speed sender on the box, then that will make that aspect easy without the need to touch the ABS. Or it'd also be easy to add one to the propshaft or whatever.
And easiest and quickest way to reduce power would be via ignition timing. Of course yes you could also do DBW, but it really wouldnt be necessary.

put 4 wheel speed sensors on it and use traction control. It would probably be nice to have dbw to be able to pull out power in the lower gears so you dont rely on tc. As not a fan of heavy cutting rather lower power to have a small amount of cut on a ideal surface.

Maximum useable power in a 2WD Cosworth ?
