anyone recognize these motors trying to find out the history/ build info on them

thanks. By looking at the paint I’d say they may have been in a gladiator

I don’t remember Zul building 700 with blowers but I can be wrong

There was a purple gladiator for sale recently with supercharged zuls.

Yea I think all the zul 700s were tunnel ram na motors.

That's what I was thinking. 700 seems to small for Zul blowers. Never seen that.

i agree. With the paint on the flame arrestor it leads me to believe they came out of a gladiator, just trying to track where these motors came from and if they are actually zuls, or were they 700 tunnel rams and someone put a blower on them ect

I've seen SC900's but even an old thread has tunnels on everything 700hp and under

Richie had a few diff combos for hitting his hp numbers, his tunnel rams were all higher compressions, but most of his blown motors for longevity were a little higher compression and lower 4-5 lb boost.. made them very reliable and still hit the numbers he wanted

yea i just never seen a 700 supercharged
