I'd pull it apart and check the clutch you have in it, the standard clutch can handle 250Bhp all day long, I suspect there must be something wrong with either the driven or pressure plate?

I've just read your post again, when you say it has the Manta box, is that mated to the Senny dual mass flywheel and standard clutch or something different?

Struggling to understand what is fitted where.... by donor car do you mean that the engine is still fitted in a vauxhall senator, or do you have an existing 24v manta from which the engine is to be removed.

Firstly, did you fit the new clutch yourself? Or have you taken someone's word for it...

Secondly, did you adjust the clutch properly to check that it is engaging and disengaging as it should?

Thirdly, Could you have accidentally contaminated the drive plate when fitting it?

More details would be useful if you want some help, i.e. the exact setup you are using (clutch, flywheel and release mechanism etc.)

If he is running a Manta 5 speed box, odds are that he is running a Manta 2,0 clutch as well, wich will not be enough for the power of the 24V. Its not the BHP thats the problem its the torque.

You need to fit a 4 plate clutch or similar, OMP makes them and so does ENEM. You need something that can handle the torque.

This leads me to a second observation. A 5 speed Manta gearbox will not survive long mounted on a 24V. You need to get the 265getrag from the Monza/Senator cars. This gearbox will take all the power you want, and fortunatly too it has a big clutch (normally handles the torque of a goldtop 3,0E)

www.enem.se they have a real old and not user-friendly website, but they are very good at tuning parts for the Opels and they know their stuff.

Dont know where to get them in the UK, im from Denmark ;)

Performance för 6-bultade 228mm svänghjul. Max. 455Nm med organisk lamell.

This will keep going to 455nm´s wich is about 150 more than the 24V engine makes. So it will hold. Order number 3082 999 618

If your flywheel isnt 228mm´s you can have some of it machined to comply with the new clutch
