Wow, right place at the right time. Good to hear. The stock map does not add more fuel as the boost goes up, its the same as stock boost fuel so it does lean up when you change the pulley size. It's a good idea to have the ECM modified for just a touch more fuel at the higher boost. For whatever reason, mercury did not even extrapolate the map. No problem other than that. Normally, I touch the boost fuel table a touch and bump the rpm limit to 5600rpm.
Thanks,
Dustin

Motor ran great with the new thermistat and pulley. One thing has me worried...cruising @ 3800rpm, rpm momentarily dropped 500 rpm for a second then came back. This happened twice on the last run of the weekend. It also happend after I switched totally to my port tank (which had contained 2/3rds last years gas). Was the ECM pulling timing because of detonation? Water was @ approx 60* and my water temp hovered around 130*. I need to get an AF meter on this and do it right.
Thanks,
Dustin

You blower guys...help a virgin blower guy out here. Did I do right or what?I have a 250 Blower shop unit with a dominator on top. The fuel pump is an Aeromotive A1000 with an Aeromotive bypass regulator that allows a 1 to 1 increase. If I understand it correctly...1 pound of boost increases the fuel pressure 1 pound, with the idle pressure set at 7 PSI. I set the timing at 28* total on a MSD distributor. All the fuel lines are stainless steel JIC fittings at -8 (1/2).
I really dont need a blower...just wanted one. Love to here that blower whine when cruising.
Thanks for any and all info and or suggestions.

Dustin??
Hey Dustin,
I have destroyed (2) both Idler pulley bearings since I added your intercoolers (within 10 hours run time since install). If you remember the belts in the kit were too short (could not get them on). The replacement belts you sent me put the idler bracket about halfway through it's stroke. The blowers were just gone through at 100 hours but Idler bearings were not replaced. Any thoughts? Just coincedence?
Thanks

Found a SKF Double Row Ball Bearing with same dimensions.
P/N 5203A-2RS1TN9, rated to 10,000 rpm. Will this work?
$39 at local bearing distributer. Merc (BAM) wants almost $280 for pulley and bearing......
