I've been to the track now with just the header and at first the car felt like it had less than 85whp, so I adjusted the timing from about 20 degrees to about 30, I'm guessing at 30, (the timing mark was way off the scale, unless I'm off a tooth, sorry I've never had the distributor out before, so tooth or slot I don't know), anyway, this is where the car had the most power, then my e-bay fuel reg. seemed to be quite low around 23-24lbs. so in a quick ditch effort I swapped in the old stock reg. and that brought it back up to 26-27, in my opinion that' still low, but it ran way stronger, almost as strong as with the t25 the way it was. So I'm thinking if I would have had it all adjusted like this with the turbo, it just might have got away from me!
