89 K5 LS3/LSA blower build dyno results

for those of you that weren't following my original thread here is the link to that:http://67-72chevytrucks.com/vboard/s...d.php?t=655082

otherwise I was able to get it on the dyno this past wednesday,and after only 2 small issues-flex fuel sender not working and then dropping fuel pressure-both of which were simple fixes,the results were about what I had expected

All pulls were made in 3rd gear to reduce the overall tire speed-and on 33x12.50x15 all terrain tires,not speed rated obviously

On 93 octane it made 540/515 rwhp/tq and pulled to 6800 rpm
On E85 it made 576/523 rwhp/tq and the same rpm

saw 10 psi of boost total-all in all I'm pretty happy now in search of a 12 bolt for the rear end before I grenade the stock 10 bolt

the only vid I have was teken by a co-worker and is a snapchat format so it side ways...sorry
