I have no doubt the Edelbrock will have a far more sustainable output.

You're absolutely right Mike. I just wanted to add that the E-Force kit utilizes .75" id intercooler hoses, whereas others are using .625" or smaller. Additionally, the waterpump flows double the amount at 8gpm v.s the older Bosch unit at 4gpm.
Based on images I have seen online, both Harrop and Cosworth are using Bosch pumps.
Lastly, fin density on both the charge-air-cooler and front heat-exchanger is key. It may be too early to find this info, but Edelbrock usually posts the performance specs of each in BTU's/hr. Basically, you can't tell how something will perform based on size alone.
