I just spent over 2 1/2 hours playing with this thing on the dyno. I still have to scan, upload and html-ize the dyno sheets, so bear with me.
I'd also like to extend a big THANKS! to Stu Krum (
http://www.schatzandkrum.com) for his patience, ideas and after-hours work he did on this; nothing like working a full day and then spending almost 3 hours working the dyno for someone...
Anyway...
The E-Ram does work. I'm still crunching the numbers, etc, but it looks like a 2-3 HP gain and a 10-12lb/ft gain in torque. While these tests were not conducted under NASA-grad lab conditions, they were somewhat consistent. If you wanna get super-anal about the way the dyno tests are conducted, I invite you to rent one and go wild. This dyno run was bordering on a 'favor' - I paid for it, but I got a lot more roller time than normal.
One fly in the ointment was the oil cooler fan which kicked in at inopportune times - inhindsight I should have disconnected it before we got started. I'd also left the stereo on for the whole test - d'oh! A small draw, but a draw nonetheless.
One interesting observation was the difference in HP and torque, and how HP went down when the oil cooler fan kicked on, but torque stayed up.
My "baseline" run was 234.7/399 - almost where it was (234.3) when I dyno'd it on 12/18/2001. This was with my homemade setup - not the e-ram or e-ram turned off.
The best torque figure was 233/412.1 (cooler fan on), the best HP figure was 236.4/410.7 (cooler fan off)
Lemme finish scanning and get back to y'all - talk amongst yourselves...
