2013 Black Diamond LSx376 Whipple charged

Just finished a neat project I know you guys will like.
Brand new (600miles odometer), loaded '13 Avalanche.

Originally had the 5.3L / 6L80e.

Now equipped with a GM crate LSx376-B15 and a 2.9L Whipple.
The engine is waaaay more than what's needed and the charger was chosen for it's larger displacement, vs the smaller 2300.

Engine: http://www.crateenginedepot.com/LSX3...06-P50811.aspx

The charger is Whipple's 2.9L, used on the new Camaro.

We also added ati crank pulley, longtube headers, 2800 yank converter, bm trans cooler, magnaflow muffler, 4" cold air tube, TruTrac posi, plx gauge and not that you can really tell, a leveling kit for the front.

TRUCK IS AWESOME!

As of now, the charger is barely working at 3-4 psi, but the truck is pretty damn quick. A new pulley is on the way to get things fun.

Goal: a reliable 600hp Avalanche. With an engine that is overdone, a charger that is barely working and staying cool, and absolutely no issues or leaks, this was definitely a success. By no means is this the fastest truck on the road, but it's probably one of my favorite builds. Considering it will never break, gets 16.5mpg and will smoke the tires thru 1st and 2nd. Idle and drivability is great. Steady at 700rpms; the yank converter helps keep the pull away at lights and really allows the engine to get into it's powerband immediately!
Obviously this combination has a ton left on the table and you're probably asking "why" didn't we want more power? Reliability!
I know I'm bench racing here, but I'd put this truck against any other and bet it could easily be the fastest Avalanche around; that is if we took advantage of the engine and chargers potential.
I know it's really hard for some of you gearheads to get over how tame this build is lol; but when you consider how reliable this setup will treat the customer, it was a good decision. However, I still think this engine should be in a race truck lol. It'll support over 1,000hp and the charger can feed the engine with about 15+psi, but it won't see it.

I've been driving the truck (customers request) for about a week to see if any issues come up; there's been zero!

Good oil pressure, engine and trans staying cool and the chargers iat's aren't worth mentioning (cool).

I'll post some dyno numbers later this week after the new pulley shows up.

I see they upgraded the rods in that motor to a forged set. ive had my eyes on that motor for yrs now and always thought it was a good bang for buck motor.

Freaking awesome build for sure. I would hope they would run minimum 6-8lbs however I understand the point of this build. Pretty awesome especially for a brand new truck.

ya, this engine is the B15, capable of 15psi per GM, which is a bunch of bs, lol. i'm sure 20psi is no problem.
replace the bolts with studs, it's got the components and block for 30psi.
i'd take this engine over all the engines i've had built by machine shops; ya bad experiences you could say.
plus we installed it (master cert) , so there's the 3 year warranty, i know it's gonna be perfect when i install it, oil pressure, quiet, everything just right!
cam seems very tame, idle is very nice as well.

i'd use this engine with new bolts on anything less than 1500hp, but i bet it could take more. it truely is the best bang for the buck.



i'd like to push it more, but everything after the engine was considered., yikes!

Nice build. That is something I would be happy with.

please post up more if you use this engine in other builds. Might just be something worth picking up then changing out to studs....

Allen nice build looking forward to the sub coming in for the set up. Keep up it up man!!

this has been one of my favorite builds this year. I think anyone would be happy with a reliable 600hp avalanche

Ray, nice work man. Ready to do it again, always easier the second time.

it will be easier second time around, considering that charger wasnt meant for a truck

Clean build this would be great for a DD and a tow truck for sure.

seeing a little belt slip on the topend, no chances:

I am sure you know this trick and have thought about it but.... Have you thought of adding an idler pulley to increase belt wrap? Something sorta like this?
http://i1142.photobucket.com/albums/...ps6ce0099d.jpg

It has two that are located under the charger pulley, has pretty good wrap.
it's a little disappointing that with a smaller pulley we're only see low boost and that we're already getting belt slip.

that's fine tho, next time it'll be mandatory 8 rib regardless of setup.

Dam nice build Allen....

which fuel pump? injectors?

Any updates?

I thought the warranty on this engine was 1 year 50,000 miles? How is that effected by the cam install? How long do you see the 6L80 standing up to this power level in something as heavy as an Avalanche? Any plans for a brake upgrade?

Not sure on the engine to be honest, rest of the vehicle is taken care of tho.

With the amount of power the customer is requiring, it'll hold just fine.

The cam is part of the engine purchase, complete long block.

8-rib setup is on and no more slipping, much better!

No brake upgrade, it's not a racer or highspeed, just good torque all around.

Sorry about that- I thought you had added an aftermarket camshaft. I double checked and warranty is 24 months/50000 miles. I would like your driving impression on the 210/230 factory camshaft on a 9:1 engine in something as heavy as an Avalanche.

Quit bogartin the dyno sheets:hyper2:

I would of liked for gm to had come with this engine sooner, they only upgraded the heads for the 6 bolt lsx and the crankshaft for the lsa they left the same connecting rods as in my engine they just changed the description to forged powder metal still same part number.
is still a better motor n would of bought this at the time if it was available :thumb:
allen pm me with a ballpark of a tvs2300 install with a ls9 cam if you can, thanks

1500hp? You really think so?

Update?

I don't have any desire to put my truck on a dyno, but I know it's north of 1,000hp easily; and my setup isn't considered pricey or high end parts.

I'm not taking your comment the wrong way, but if gm mags can make over 1000hp with stock production blocks; I have no doubt a 2000hp capable lsx 6 bolt block, good flowing LS7 heads and intake, and forged components will support more.

ya, it was 580hp and lots of torque.

before anyone says they know of a 4.8L that can make more and these are low numbers, hahah, keep in mind what the truck is used for.
it was a brand new avalanche, nobody wants to be replacing parts and smelling fumes in a loaded av.
plus, i think 580 at the tire is doable for all those stock drivetrain parts.

obviously an lsx376 and 3.0L whipple can make some good power if pushed further.

thanks,

Awesome write up.....Thanks !!

Hey awesome build! I have a few questions with it. What water pump are you using? What alternator bracket? And are you using the factory power steering pump?

We are using the new camaro water pump. offset is the same as all the '07 truck engines.

alternator bracket is the one supplied by edelbrock i believe. sets it to the side as you can see.

yes, factory power steering stuff.

Do you recall what the part number for that bracket is?

sure don't, it's edelbrock tho. i think it was a spare or we got it from somewhere else, possibly a spare part we had here.

Wish I could see those mpgs out of my charged setup!!!
