Too much to list really, you should browse through the thread...
A short version of my project: 2007 Yukon Denali, Built/Forged 402" Iron Block, Lunati crank/rods, Wiseco Pistons, BTR Stage 3 PDS Cam, Brodix 6 Bolt CNC Heads, Fully ported LSA Blower, ZL1 Lid reinforced, 2.5" Upper/10% 9.1" ATI Lower (14.5-15psi), Kooks 1 7/8" Headers, Gutted Kooks Y Pipe, 1000cc FIC Injectors (I have ID1300x2 injectors going on in the next week or two), running pump E85, Mishimoto Radiator, HD2500 truck fans, Custom Blower Chiller, QA1 Double Adjustable Coil Overs front and QA1 Double Adjustable shocks in the rear, Front Drop Spindles, Rear 4-6" Drop springs with bags. Transfer case was original and just rebuilt a few weeks ago along with another fresh transmission build (broke an input shaft). Running a Circle D 3k Stall Triple Disc convertor. Self tuned with HP Tuners. Front diff is rebuilt to OEM spec, rear 10 bolt Diff has a TruTrac. Best ET was an 11.77 @ 124mph and that was in November here in Michigan on SNOW TIRES spinning all 4. Planning on stepping down to a 20" light weight wheel and running drag radials on all 4. I have 16" Wilwood brakes waiting to go on sometime this month. Full 5" intake and MAF only tune right now.
Honestly, probably forgetting a lot... Probably making just over 1,000hp but I will get it on the dyno for a solid number.
My IAT cruising around has gone up slightly since I removed my heat exchanger fans. I'm also running a very thick exchanger that doesn't allow a lot of air flow at low speeds. Without the chiller, I see 30* above ambient right now. Usually only 15* when it's warmer out. With the A/C Chiller turned on, I see temps right at ambient or 15-20* below typically. Temps don't go above 115* after a 1/4 mile run and quickly recover to 15-20* below. Before my chiller, I would see 160-200 degrees on a long hard freeway pull. No longer an issue and the chiller will be working better when I get my A/C problems worked out (currently have a blockage or bad compressor).
I'm running MAF only because it works really well for me. I don't have any drivability issues and I don't need to make big changes when the temp changes or for altitude. I have considered getting my speed density dialed in so I can run a blend but I do not plan on getting rid of my MAF, no reason.
I use a Granatelli 103mm TB now and LOVE it... No issues like I had with my NW 102mm unit. You will notice more power/performance if you upgrade, ANY restriction before the TB is lost power on these blowers. Get the biggest intake you can fit and get a Granatelli 103mm on there. They are cheaper than the NW units.
