Curious what engine this is going in? The thread is in the MK1 section and the only hydraulic MK1s that I know of are cabriolets, the very last ones. All the rest are solid lifter.

I common engine transplant for mk1s is a mk3 1.8. These later model engines have hydraulic lifters, as do many of the other large block 4 cylinders from 1985 onwards.
LOL I know the transplants, I have done a few in my time. You hadn't mentioned in this thread what motor and I was going to point out that solid and hydraulic cams are very different. Which you know, but others who might read in the future don't.
I had a 282 in a 2litre MK1 GTI tears ago, which also had a BV head. That didn't rev to 8000 even before the 2 litre conversion. So I am not seeing yours go that high tbh.

I had no intention of being condescending, as you certainly seem to know your stuff. I too am doubting its potential of getting to 8k and have revised my goals accordingly.
The specific engine is a later model 1.6 oversquare engine, code AFT. It has more potential for top end power than low end torque, hence the question was asked lol.
What was the power delivery like on the high duration 2 liter? Just incase I wanted to track down a cam around the 280 mark [emoji6]
It was very driveable as an 1800. The torque was great as a 2 litre but it lost a lot of top end reviness, partly as I had to take the 4 branch off though.
The head work was the major thing with both of those motors. Vernier pulley essential.!
Back in the 90's I used to hillclimb my MK1 and the fastest car in class (and 2 seconds over 40 seconds faster than me) was a 1.6 1982 Passat driven by a woman. Her husband was a mechanical engineer and built the engine. I spoke to him about how fast the Passat was and his benchmark was Holden V8s. If it was slower than the V8 he would give it a tune.
I also spoke to his wife and she told me she could go at least a second faster but didn't want to embarrass her husband by being too fast.
And don't diss the 1.6, they were used in Formula 2 for many a year and produced some big hp numbers.
