They will tune/Dyno with the existing 2.3" & 9.45", then pop the 9.6" lower on and tune/Dyno and see which works best out of the two combos. Mike will let me know the results and then we'll decide which combo to leave on the car!

So, after Jax Wax Street Madness drag racing this Saturday. I'll be taking the car up to Katech mid/end of October/first part of November. I got some really good feed back form Joshinator99, radz28, RobZL1, Gabe, King and many others. I realize this build could push the car to the edge of street driving and enjoyability. But, I mostly drive to/from Car's and Coffee, Car Shows, and racing. My car was and never will be a daily, so I think being on the edge will be ok. Maybe after I get the car back and start driving and enjoying it for next summer, fall may be the time I add the Maggie if I feel something needs to change with the build etc. !!!

Build as planned:

Katech Track Day CAM
BTR Dual Value Spring Kit
Katech/Johnson Drop in Lifters
GM Lifter Trays
Trend 3/8 Chromoly Pushrods
Katech VVT Delete Front Cover
CNC Port Cylinder Heads
Competition Valve Job
Hand Blending
Competition Cylinder Head Assembly
GM LT4 Head Gaskets
ARP Head Studs
DSX 9.60" Lower Pulley
Gates HD Green Belt to Proper Length
Katech AFM Delete Valley Cover
GM LS Style Front Crankshaft Seal
GM Crankshaft Bolt
Katech C5-R Timing Chain
Katech Timing Chain Guide
Katech Oil Pump / Billet Wet Sump
DSX Aux Pump Kit
Fragola Fuel Tank Fitting
Brisk Racing Plugs
Coolant, Brake Fluid, Oil & Filter
Gen-V Dyno Tuning including TCU Tuning and Street Tuning
Installation / Build
Build looks great! I have one complaint if I may: the DSX Aux pump does not belong on any car, period. Puncturing the fuel tank below the fuel line is a bad idea and not safe. Furthermore that tank was never designed to be tapped and threaded, and is not thick enough to properly seal an NPT thread. But OEMs never puncture a tank below the fuel lines for fire safety reasons so I’d highly suggest you do something different on a nice build. Both Katech and DSX make proper in tank solutions as does Fore so I’d recommend going with one of those options.

Good point. Should I request replacing the current Katech Dual Drop-in fuel pump be replaced with a pump capable for handling over the 900rwhp their dual pump is rated for? What pump would that be?

Thanks!

Ask them to put an additional bulkhead in the existing dual drop-in pump's hat, and run a hose down to the bottom with some holley hydramat and magnets on the outside of the tank to hold it in place.

Scroll through the pics here for an example of this.

This could be a nice option for their in-tank pump, in general, for higher hp builds if they aren't going to run the bigger Ti 285 or 295 Hellcat pumps.

Congrats on pulling the trigger, can’t wait to see the results! Super excited for you man! Gonna be a blast once Katech is done with it. I did notice the Fragola fuel tank fitting on your parts list, so it looks like they might be using a proper bulkhead fitting instead of tapping directly into the thin plastic wall of the tank. That setup should be a lot cleaner and safer.

Still below the tank fuel level FYI… so it does fix one problem but not the main one.

Cam or no cam, 2650 or 1740, meth or no meth, chiller or no chiller, it's all good in my book. Many people have had success with all manner of combinations of parts. So I say, choose what makes sense to you (that Katech also says will work), stroke the check, and watch your grin get bigger when you get the car back.
Well said my friend, well said!

Sure their a good shop but their looking at their invoice.....and your card number....as are all businesses as they should....before they are YOUR end goals!

clg82 - Good points I agree and I get it I feel that Katech advises me well. They also listen well, to what I keep saying I want, I want ot change and what end result I'm looking for. In fact I've run Mike through the ringer, I just courted up the build quotes he's sent me since May and I'm on #9 for how many times I've changed my mind of things! I know Katech is a big price tag, but, I'm ok with that. Also, I realize the factory blower is being pushed to it's max effort. But, yep, how loud the whine is, it's crazy loud! But, also CRAZY AWESOME! I love it, I love that people can hear me driving down the street, and know that must be "Scott"! It's kind of something I actually prefer. But, to be clear, Katech originally suggested the Maggie for my build, but, like Gabe, I really like the factory blower being max out and the with the x-ported and the lid and the whine. I'll update if I change the build obviously! Thanks again !!!
You forgot, the smile you get every time we are on the phone while your driving a you hear me say.... "holy sh*t that think is loud" ... it is literally impossible to have a conversation with how loud that damn blower is
