Early 86-90 Hip hop at wrong speed?

Does anyone recognize this?
Sounds to me like Mantronix / T La Rock style production, the fact that I think it's played at 45 rather than 33 doesn't help. I've tried to slow down the sample half way through, nearer the possible original speed.
Fingers crossed!

Bump!

Found it at last
Raw Dope Posse - listen to my turbo - YouTube
I was right, it was the speeded up instrumental from 33 to 45
Thanks to all those that had a look for me. Hype used to bust this as a 'Turbo mix'.. clue was in the title!
