Harrop HTV 1320; Finally Installed (Pics and tuning vid)
Well ladies and gentlemen, I finally installed the HTV blower. Like discussed in the "First HTV blower" thread, there are a few things that need modified. I swapped the stock BPV onto the HTV to make use of ability to decrease boost in 1st gear. The supplied BPV only has one line running to the blower to recirculate. It's not needed to swap BPV's if you aren't going to use HPT to limit boost, but you'll need it to get traction 
The MAP needed dremeled for fitment and the fuel rail needs removed to access the top bolts. I was able to get away without grinding the bolts on one side to get them to fall into place. Let me tell you, if this blower was any bigger, it wouldn't fit. After making the needed adjustments, it fits flawlessly.
I took it out for a test drive and nearly wet myself. The sound is definitely unique, kinda like a whistle under light load reminded me of a turbo. The throttle response is quicker, pressure builds quicker and best of all my cruising IAT2's varied by only 10-15 degrees form IAT1!! Didn't get into it too hard as I didn't have time to tune it out tonight, but IAT2's never broke 130 with IAT1's of 88. Improvement to me!!! I'll be more in-depth tomorrow, but for the time be-ing, here you go!
