good luck with the sale
Thanks. I agree. The MP62 is some serious fun. And, the Coldside's response is sweet. If I thought I could get it to over 300whp, then I would keep it on (and I've thought a lot about this - no easy task).
I've been asked about what's different from my kit to the current FFS Coldside that Tom is selling. So, I'll just cover it here as well.
Here's my understanding of the major differences:
- eCool - Original BRP did not have eCool. I upgraded when Tom added it. The retrofit, however, is added through the Supercharger adapter plate. The current manifold has eCool threaded directly into manifold. Tom indicated that the retrofit location provides equivalent performance to it being in the manifold.
- Vacuum line's - Tom upgraded the vacuum line layout twice (as I recall) once to include the distribution block and again re-routing the IAC and valve cover hoses. I upgraded both times and I'm using the current configuration.
- IAC location - IAC was originally mounted on the supercharger but the mount experienced numerous failures. Current location is on the firewall next to the distribution block. I upgraded to that location when Tom made the change.
- Fuel Management - The BRP Coldside came with the JR PowerCard originally. They switched to the ELF and I upgraded at that time (at considerable cost because that blew my f@#%ing engine). FFS stuck with the JRPC and added the Split Second Additional Injector Controller to control the eCool injector. I upgraded again during this time. Currently, however, two PCPro's are used to manage fueling and eCool.
- Throttle Cable Adapter - The original BRP adapter was reshaped from the original bracket. The current version, I believe uses a machined piece. My mechanic upgraded this when he put in my built engine (this one I'm less sure of because I didn't install. Could be my mechanic designed the replacement - but I believe he got from Tom).
- Automatic Belt Tensioner - Originally, the BRP Coldside had BRP etched into the Belt Tensioner. When FFS was launched, they switched to "FFS" etched into the Belt Tensioner. Later upon getting CARB Approved, they added the EO sticker verbiage and number to the Belt Tensioner. My belt tensioner still says "BRP"
I believe that about covers it.
