Due to family size I need to go to something bigger truck wise. I don't like keeping stuff stock so wondering if anyone has used a 2.9 Whipple on a 6.2 escalade or what would be needed to make it work?

I think the 2300 would need to be spun more and id rather have a 2.9 whipple spin at 8 psi on pump then a 2300 spinning 8 psi on pump gas

How about just installing a tvs1900 on it? That'll be more than enough!
It will make great power and instant response.

I on the other hand, I'm gonna do twins on my caddy .
Just for show tho.

I echo what Allen says. We put a TVS1900 on our 07 Denali shortly after we picked it up in August. We are VERY happy with the power output and acceleration! I have not Gteched it 0-60 but if I had to guess I would think low to mid 5s.

Damn can't wait to see how the Caddy runs with twins!

On a side note, selling the Escalade you checked out for me 4 years ago Allen.

Not sure if anyone has put a 2.9L on a truck yet. I looked into it a little based off the camaro kit, but never thought it over much on how to make it all work. The main thing is just the intake of the blower being on the opposite side from what my truck is normally. I'm sure if you called whipple they'd be able to go over a few options with you if you're clear about what you want versus what they currently offer.

If you want to do the math on rpm of the blower I can offer up the info that a 3.375" pulley on the 2.3L provides between 8 and 9 pounds of boost depending on ambient temps and when mounted on an otherwise stock L92 motor.

I installed a 2.9 Whipple in a 2003 Escalade. There were definitely a few tasks to overcome.

care to share your experiences?

you're not pushing a 2300 on 8psi on a 6.2 I can tell you that much, stock ZR1s run 10.5psi with the 2300 and modified ones have gone WAY UP.

I run a 2300 on my 427 and its all good, running 8psi.

I will try to give a cliff notes version. Whipple recomended the 2.9 for my 408 build as opposed to the 2.3 based on what i was doing. It started off a little rocky when i realized i was putting a square peg in a round hole but they were there to answer any question(s) i had as i uncovered new challenges. Unfortunately they don't make a kit for it so i had to do all the designing myself. Many hours of staring and thinking. I have a new found understanding why already made kits cost so much...R&D!

I don't know if the newer 6.2 Escalades come with the L92 heads, rectangle ports but in 2003 they came with Cathedral ports head and to my knowleage the 2.9 Whipple can only be used with L92 style heads.

The first challange i saw since i decided to go with the Camaro 90mm throttlebody was needing to move the alternator, plus to upgrade the TB on a truck you need a special adaptor to allow it to open past 80%, tripped over that one before i installed otherwise i would have never known. I could not find anyone that make a relocation bracket for trucks so I wound up designing my own alternator/power steering pump bracket to move the alt to the side to clear the throttle body accuator. I wound up taking a few parts from the new Camaro to make it work easier, plus having the Whipple Camaro installation manual in hand kinda leaned me that way.

I wound up using a Camaro water pump due to the postioning of the truck pump neck, only draw back i have to remove the radiator hose to change the serpentine belt, hopefully wont have to do that too often. I went with the Camaro EVAP purge solenoid and lines. Since the trucks fuel regulator was basically built into the intake plenum i went with a Aeromotive bypass regulator. Initially tried factory lines with a boost a pump and ran out of fuel pressure so i dropped the tank installed a sump to feed an A1000 pump feeding the rails with -8 an lines, plenty of fuel now when hitting 18lbs of boost.

I know there were a few more things but i just cant think of the right now, possibly blocking them out, this thing was like peeling an onion.

Once i finally got it running i had a hard time finding someone to try and tune it. No one around here has a AWD Dyno that can fit the ESV with a 120 inch wheelbase. Blew a full race built 4l60e in 4K miles and installed a 4L80e and tried 2wd, finally got it on a dyno 840 ftlbs of torque. No traction so i am in the process of converting it back to AWD.

Heres a couple of pics.

Hell yeah, it's damn nice!! 840 tq at the tires ain't too shabby either! I'd like to see the dyno sheet on that if you have it.
