Stiegemeier porting before/after dynos

[littlejohn]

Had a Stieg ported stock Eaton installed and dynoed today up here in Canada; the temp was cool, however altitude of the city is around 3000 ft. Pulls with the stock blower were 580 sae initial and 574 back up, only 5 min. later.

The ported blower ran 601 sae on both tests, again only 5 min. apart; it seemed the port def. runs a bit cooler as there was no heat soak drop like the stock blower.

Mods are: Stieg ported 2.1 Eaton, 2.6, I.W. lower, Whipple monoblade, C&L cai, Kook's LT's and o/r pipe, and JBA 3" exhaust, Truforged reservoir. Stock gears.

I'll post the dyno sheet as soon as I figure out how to attach.

Hopefully more guys will start to maximize their stock blowers! I just installed my lower pulley, CJ TB, and ported my blower as well. Throw a shot of n2o on top of your combo, i promise you wont be disapointed lol.Thanks for posting up your results!!!
