S465? That was THE turbo to have around here when it was the 2.5 class years ago. Of course then 2.6 & the stepped wheels showed up & you know the rest.

65mm = 2.559" Inducer = 2.584 Bore = NO GO! Not picking on ya, just stating it so its known. Gotta keep the bore under 2.55" to pass tech.

What pulls let you run a 2.5"?

BOB is going to it next year, others run it already. since we hurt the stocker we decided to step up, pull anywhere and everywhere we can and dial her in for next season. trucks still drove on the street and with the new found fuel she was impossible to keep cool to have a lot of fun without worry of severe damage.

I'm interested in this setup as well. I'm from the south central pa area where there are several pulling organizations present. I spoke with some guys from full pull productions earlier in the year and they mentioned they were interested in possibly putting together a 2.5 work stock class. Also went to an interstate pullers meeting the other night and they expressed the same interest and we suggested a 2.5 work stock class. They were very interested as well. It'd be nice to see several organizations in the area adopt the same rules (or similar enough to make some easy changes) so that we could get some good 2.5 trucks going!
