I'm too lazy to run back through this whole thread again, what all is done to it again?

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.

Very nice build!

How has that throttle body been working? I've been running an LS2 90mm on my Magnusson for a few years without issues but I'm scared to upgrade to a Nick Williams.

Also what do you IATs look like with the chiller? I typically see 10-15* above ambient normal driving and have seen close to 140* after a 1-2-3 gear run.

Lastly why are you sticking with the MAF? I switched to speed density when I first put my blower on and have had no issues with it.

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.

That's awesome to hear about the Granatelli! And the interchiller sounds really badass! Not sure I'm ready to go that far since I don't race but that's the first I've seen done like that seriously nice job 30* below ambient is incredible without an ice box. Especially with an LSA which I've seen tend to get a little hotter than other TVS rotor setups. :waytogo:

If MAF works for you I'd stick with it too.

Seriously sweet build I will be watching!

I do have an Ice Box that acts as a reservoir for chilled fluid during a long pull. I don't actually fill it with ice. Thank you, it's been a ton of work to get it to this point but it's been worth every hour and dollar. I don't have a ton of money into this build and you couldn't buy a car or truck like this. It's become so much more than I anticipated and will be even more happy when I click off that 10 second pass here soon. This is still a full weight truck with a spare tire and my kids car seats in the back lol... It's gonna make a world of difference when I cut 15-20 lbs of rotating mass at each corner. Can't wait!

I've got a 2 gallon Icebox too but have only iced it one time for fun. A 10 would be absolutely nuts in such a big truck. I think my RCSB probably runs high 12s or low 11s if I put it on a real tire and its scary to drive lol.

I bet the guy in the Vette was surprised... lol

Friggin badass! You beat the vette too? I hope so :D

More shocked then surprised lol.

I most certainly beat the Corvette and it was on drag radials, definitely not stock either. A few guys came up to me after that race and said, “holy crap, is that thing on snow tires?” lol... sure was and the next day we got 8” of snow. Guess who had to park the race car and guess who was out playing in the snow lmao
