SOHC Times/power??

[sbutler]

With everyone spending big bucks on the boss motors:eg: bolt ons, edits etc.etc,to get into the mid 13s. Has enyone had a go at the SOHC BAs yet??
We stuck the Gtech in the Young fella's car the other day, & ran a few 14.5 to 14.3,
That was the best I could do. Since then, we've done a full twin 2.1/2 cat back, exhaust system & put some 18X8 wheels & tyres on.
So is there any reason this thing should'nt get into the high 13s???
Iv'e had a bit of a look at the stats, & the XT V8 is a bit lighter than the GT/XR8s so thats gotta help, although not having the top end of the DOHC motors. The rev limit is a bit of a problem too 5200rpm is a bit soon I think, the motor pulls well to the limit but you get to it to fast.
Is there any reason the limit is so low on the 3V compaired to the 4V motors? there basiclly the same bottem end.. :
