LSA Escalade

[Yukon_inferno]

Hello-
I am new to this forum, and am building an LSA Escalade setup. I am sure there are some on here but I am still trying to navigate. I have a few questions regarding the setup though- and I figured some of you guys have been down this road.
What I ordered from BoostDistrict:
The LSA kit with

• Lower LSA supercharger
• Supercharger Snout
• Solid Isolator
• Bypass Valve
• ZL1 SUPERCHARGER LID*
• OEM LSA fuel rails*
• Upgraded Heat exchanger
• Heat Exchanger pump
• Truck BELT DRIVE ADAPTER KIT
• 1/2" HEAD ADAPTER KIT (FROM SQUARE PORT TO STOCK CATHEDRAL HEADS)
• 850cc injectors

I plan to run E85, and about 8lbs of Boost.
What are you guys using for fuel pumps? I know my current stock pump is E85, so flows more than the gas setup, but I am pretty sure I need more fuel than it can deliver. And if you are using higher flow tank pumps is that adjustable through tuning? I’m not new to building go fast toys, but this setup is new to me. Any help would be appreciated! Thanks!

Welcome to the Forum from NH.

I have no experience in supercharging, and as such cannot help you, but you are correct in that some of the folks here do have that knowledge and experience. They will chime in with their experiences and perspectives.

Good luck on your LSA build!

Maybe these guys can help with some of your questions.

@Rocket Man is running a SC.

@randeez is running a turbo but has a pretty elaborate fuel system if I recall.

There are others that I can't think of right now but perhaps @swathdiver can post some other members that are boosted.

fuel systems....

fore warning - i left the stock flex pump in place didnt touch it, sumped the tank and threw in a magnafuel 750 (close to 1k hp itself) as a secondary pump. i did this so that i could still use remote start, use the stock pump cruising around and not have to hear the big boy all day, if one dies the other can just be turned on to get home, etc. and i also over kill everything

stock flex pump was good for about 400-450hp on e85, 600ish on 93oct i started having long term issues with running stock injectors over 90% duty cycle. best guess i have for stock pump is about 380lph

i believe the stock fpcm has no problem working with a single walbro 450, but iirc they'll do 550-600hp before theyre out on e85. i think at 8psi you'll be very near that area but its always good to have some buffer.

theres the "hellcat" pump out now, walbro 525lph, havent heard of anyone running one on a fpcm. they draw a lot more amps over the 450 and dont flow that much more.

I would AT MINIMUM do a single 450, and just plan on pretty much max'd out. if you want to come out of the gate over prepared a pair of 450s in the tank is a stout fuel pump set up.... likewise a stock flex pump and a 450 should feed over 800hp easily. i think the stock in tank basket will hold two 450s, run the second one off a hobbs switch (pressure switch)

injectors....850cc to me are right on the edge again, which sucks cause after that they get expensive. you have an inverse relationship for pump and injector. injectors flow more at higher psi but pump flows less at higher psi. 850cc will flow 700hp@ 70psi but a single 450 isnt going to get you there \/ thats walbros pump curve for a 450lph

My single 450 in the stock bucket on -6AN line worked perfect up to 800hp (14psi) or so. I didn't add my second 450 on a hobbs switch till I switched to E85 and now closer to 900-1,000hp. Use a RaceTronix wiring harness to supply the pump with enough power and it will be fine for 8psi. If the OP wants, I have stock LSA injectors that should be good up to 650hp or so but will be stretched on E85 if pushed hard. Do yourself a favor and get 1,000cc right off the bat and pay attention to injector ratings at certain PSI. You want to run 58psi at the rail and make sure the injector is rated for 1,000cc @ 58psi, not 45 psi.

What year is your truck? Mine is an 07 and doesn't have a FPCM so it was very simple... Do yourself a favor and keep it as simple as possible. If you're not running bigger cubes or a ported blower/heads then a single Walbro 450 should be just fine. Very easy to drop in place of the stock pump and very reliable . Pump won't be tunable, you would set the pressure at the rail with a regulator and a return line going back to the tank. Use the factory feed as the return line and drill for a bulkhead fitting as the new feed. Set rail pressure to 55-58 psi and forget about it. 8psi on an LSA is very mild so I wouldn't worry too much.

Go look up FasterProms on youtube...he has an LSA setup on his wife's escalade. It pulls tires on stickies on the track. Full build video is on there for ya

He did put it in the 07-14 tho.

Who are you referring to? Which member?

OP--@Yukon_inferno

 

[Yukon_inferno]

What year Escalade? NNBS or nbs

2013 (I hear NNBS and Nbs) and I don’t actually know what the acronyms are. I assume new new body style, and then just new body style?
Either way, 2013. Lol

Yea, I would like to keep it fairly simple. I was looking as of the last few days at a Walbro 450, and the hellcat 525. I will use HPtuners to bypass the FPCM and set the regulator up as you Guys have mentioned. I am feeling more comfortable with the setups than when I initially started looking at these setups. I’m still not positive on what to run as far as AN sizes, line lengths, etc. I had considered doing the twin pump setup on a HOBBS, because I like to be ahead of the game and have plenty rather than cutting it close.. so I’m still not sure which is the best route.

Yes--NBS=New Body Style

Thank you for this information! So, the only way to continue using the remote start is to us the FPCM? I live in Indiana and remote start is a nice bonus to have in the winter.
Seems to be a lot of options. I tend to overkill most projects, but this one I would like to keep fairly simple. But a twin pump setup, and running the second off a Hobbs- that would allow me to use the FPCM or no?

 

[Yukon_inferno]

Also, thank you guys for the information and help. I apologize for not getting back on here in a few days, I had two sick little guys and it’s been hectic. I also didn’t get any alerts that I had received responses or I would have been reminded of this thread. But anyhow, thank you

what style heads come on the 2013 NNBS?

 

[lt1z350]

My 2007 Tahoe with lsa 1000cc injectors 14 psi a few bolt ons ran 11.7@114 mph 6l80 swapped also. And I was on a Delphi flex pump and a msd bap. I ran that combo 7 years until the Delphi pump crapped out. Now that same combo on the lsa injectors and 93 I ran it no bap and was just fine. I had to add the bap when I did the injectors and e70 a good 100whp gain. My first day out I beat a 2018 bmw m4 to 100 mph. Lol truck was moving out for a stock 5.3 combo. Now on a .060 6.0 ls3 heads a cam combo I did a 450 in the factory fuel pump bucket with a lsa zl1 regulator and still using that 7 year old msd bap it’s fine so far. I know many say they do not last but mine has been fine for all these years and the only thing that failed was the Delphi ethanol pump I threw in it at 80k miles when I did the blower. I took the 5.3 out at 210k the pump finally crapped out at 18.5 volts after all these years right before I did the engine swap. So did the 450 knowing I was going to need more. And on this year no return line setup with I don’t have a pressure issue with it running away at idle still stays around 58 psi and wot I see 80 psi with the bap. So like others have said your 8 psi combo the flex pump will be enough most likely. Worst case will need a bap on it. I didn’t see if your a 5.3 or 6.2. If 6.2 most likely will need that bap on it running e85. It is worth leaving it alone and putting a mechanical gauge on the rail up to window and see what it does before go out and buy a bap. I would not mess with the pump at that point. Just throw 18v at it and it will be just fine. That’s what 90 percent of the boosted c6z guys are doing or guys on nitrous as the c6 tank is such a ***** to drop it so a bap is very popular on those combos.
