: Garrett AVNT 37 Upgrade
Brayden 09-19-2008, 09:01 AM Garrett's decided to come out with a high performance VNT for the performance crowd. I am stocking these turbo's as are a few other dealers. We have 5 in stock and are ready to ship.
The specs ....
The turbine is of stock diameter yet is changed to a 10 blade design (higher flow) which produces the whistling sound similar to a cheetah.
The vanes are unchanged in profile and are the same dimension as an LLY.
The compressor is 65mm in the inducer but 94mm on the exducer.
We're installing one now to test but I'm thinking this turbo will most likely run out of steam before our cheetah's do because of the smaller stock size turbine.
For the 500hp guy or anybody who tows this should be a good turbo.
We'll be offering these turbo's with an upgraded turbine and compressor just as we have with our Cheetah lineup.
Thanks,
Brayden
Brayden 09-19-2008, 09:07 AM BTW.. The turbo is NOT stock appearing. The cover looks different for those of you who are sled pullers. ;)

Exactly...:D
jrad12381 09-19-2008, 11:45 AM You will have too keep us posted on how they compare. Like you said above it sounds like it will fall short for the performance guys.
fire0021 09-19-2008, 11:49 AM with the upgraded wheels does tht basicly make it like a current cheetha ?
jrad12381 09-19-2008, 12:29 PM with the upgraded wheels does tht basicly make it like a current cheetha ?
And how much does the upgraded wheel cost. Can you put the 71MM in there.
gasuout 09-19-2008, 03:48 PM Thanks for the descriptions of whats in it , and cant wait to hear how the testing goes .
Keep us informed on it , and Im still loving the lbz cheetah 68 on the kodiak .
It works great . No complaints what so ever .

Brayden 09-22-2008, 08:59 AM Yes...
I can take that charger and modify it to make it like the current cheetah.
It won't be stock appearing though.

Brayden
would there be any benefit in useing this new charger with bigger wheels or basicly be the same. Thanks also give me a ring today if you have a chance thanks
Brayden 09-22-2008, 09:41 PM No benefit that I see.. I have an LBZ Cheetah owner swapping over to this charger to do a comparo... He'll provide feedback this week.

gasuout 09-23-2008, 11:10 AM If the exhaust housing is larger wouldnt it have a slower spool ?
irish yankee 09-23-2008, 11:29 AM I thought 500hp was possible with a bone stock charger?
fire0021 09-23-2008, 11:37 AM If the exhaust housing is larger wouldnt it have a slower spool ?
not if the vanes compensate for tht
01Duramax6spd 09-23-2008, 01:30 PM It is easily with EFI. I'm pretty certain I'm over 550rwhp on my stocker. Dyno will prove one way or another soon I hope :D.

HeavyHD 09-23-2008, 06:28 PM Be tough to get over 550 on a stock charger and if you did the drive pressures have to be crazy. Let us know what your results are when you get it dyno'd.
irish yankee 09-23-2008, 06:58 PM If you can't beat them join them yea:rolleyes:
AGGAR 09-23-2008, 07:23 PM I thought 500hp was possible with a bone stock charger?
It is, I've done it.
z79outlaw 09-23-2008, 07:40 PM Is the compressor housing going to be more efficent on this than your 64mm Cheetahs, say if you used the Garrett AVNT 37 and your turbine and exhaust housing like you say is possible, would this be beneficial for say 2.5 or 2.6"?
Brayden 09-23-2008, 09:41 PM Compressor housing is not any larger than stock. They did incorporate the scroll into the comp cover instead of the backplate but that doesn't really change anything.
The exhaust housing is pretty much an LLY housing for all practical purposes.
Brayden
Brayden 09-23-2008, 09:42 PM I would say that you'll be close to 500hp and I hope you can hit higher but I'm not thinking so. Most will just tickle 500hp.

01Duramax6spd 09-23-2008, 11:39 PM The tune has proven 552/1135rw already in a stock turbo'd Ally truck.Just a tune,FASS pump,fuel pickup,exhaust,ect.
I guess we'll see how mine does. You know numbers pretty well but I think you'll be suprized,or I will be :(.

gasuout 09-24-2008, 12:12 PM Thats higher #'s than any Ive seen hear on dyno's . More like low 500's with that set up . And thats getting every last drop out of them .
Dont know where your getting 50 more hp from .
jdugie123 09-24-2008, 02:52 PM so just to be clear if you were to upgrade this turbo with a new compressor you are getting a cheetah that is just not stock appearing really right
Brayden 09-25-2008, 06:21 AM No.. Not at all. That's what I'm trying to convey really..
It's more like a stock LLY turbo with a compressor upgrade only than a Cheetah.

x2, most I have ever dynoed was 545 out of an LBZ and it was Ratlover's and it had all the little goodies but had the stock charger still and his tune. Average i see out of the stock charger on LB7 475-530 LLy 455-510 LBZ 475-520 this is largerly impart the the condition of the truck and how much stuff has been done to it with the stock charger. You might prove us all wrong though, but I have personally dynoed alot of trucks and I don't see it happening.
fire0021 09-25-2008, 09:55 PM my truck dynoed at 536 with stock charger
01Duramax6spd 09-25-2008, 10:05 PM Not to keep steering this off topic but mine made 475rwhp over 2yrs ago with just a old VA 200. No other mods at all other than a clutch. Stock exhaust and intake. As far as the way it feels driving it,I'd say I easily have another 50rwhp,maybe more.
On topic this new Garrett good for 600rwhp?? Maybe I missed it but is it a 2.6 charger?
jrad12381 09-30-2008, 05:39 PM sooo whats the good word. Hows this turbo compare to the cheetha Brayden?
irish yankee 09-30-2008, 05:55 PM If this new charger will hit in the 600hp range then I would think Brayden has some work to do;) Still love the cheetah whistle though
fire0021 09-30-2008, 06:22 PM cheethas will make 600-650 all day long
MarkBroviak 09-30-2008, 07:20 PM If this new charger will hit in the 600hp range then I would think Brayden has some work to do;) Still love the cheetah whistle though
It takes more than just the charger to make power, got to have the proper fueling to make that power level. I am more apt to agree with Brayden that his chargers are capable of making more power than this one but time and a dyno will tell the story. I think that the tuning almost plays a bigger role in the power that is produced than the charger itself does. I am pretty sure I was able to prove that point this year with Gainer's truck as it has a little ol' DP GT3888R on it and it did great agianst much larger chargers this year.
SteveFord 09-30-2008, 08:00 PM All these claims of dyno numbers means nothing in my opinion. Take it to the track and see. Pulling has alot of variables to see what works better but the same truck running at the strip is a better comparison. Say you have an lbz and your running mid 12's. Dropping $3000 for 2 tenths to me isn't worth it. Just my opinion.

I see your point but there are alot of guys that think 5ft is worth $1,500...
SteveFord 09-30-2008, 08:53 PM I see your point but there are alot of guys that think 5ft is worth $1,500...
Very true and a good point for pulling.
Brayden 09-30-2008, 09:39 PM I have an LBZ with 45% nozzles running this turbo now and he's already missing his cheetah :( I can't print his exact words though
He's pretty disappointed in it.
The turbine is too small for the performance crowd. I'd say it's going to be difficult to get this one over 600hp.

Or more!
MarkBroviak 10-01-2008, 01:53 PM Or more!
Yeah, depending on which 5ft you are after!:D

Got talked into trying one glad I did now Im putting a cheetah back on. Same tuning netted 7 psi less boost and 200 degrees of egt more. Have not dynoed and will not because the cheetah is going back on tuesday. The turbo has a stock soud to it I and that might be good for some but I miss the whistle of the cheetah. The cheetah cleaned up the availible fuel and this turbo still leaves a haze of smoke. Probably great for the average joe but who wants to spend that kinda money and be average. We worked hard to get this turbo on my truck the first was shipped with damage to the vane control senor and the v band ring the second had a damaged vane control sensor. Garrett needs to rethink their packaging. Many thanks to Brayden for his shipping and reshipping to get my truck on the road. After all he talked me in to this trial. He wanted some one who has run the cheetah and could make an honest comparison and I did and now Im ready to go back. It reminds me of the bd I had on my lb7 a good turbo just not a great turbo.
SteveFord 10-01-2008, 09:59 PM Wouldn' this turbo need some custom tuning done to reach it's potential also since it's different?? We need to see one with it's own tuning done to see where it stands. I'm not trying to start anything here but what a comparison thats is more fair. Just my opinion.
Brayden 10-01-2008, 10:02 PM Adding more vane position is going to increase drive pressure. Apples to apples this turbo makes less boost on the same tuning. If you tune for more vane position backpressure goes up and hp will go down.
SteveFord 10-01-2008, 10:07 PM I get that I just thought this turbo had different vanes as a more high flow style. Atleast I thought thats what Dan said. Thats why I figured it would need different tuning.
