30 lbs of boost

[DIXIELAND DIESELS]

Will 30 lbs of boost hurt my stock LBZ motor? I am running a smoke tune I got off of DP. It runs great I smoked a Ta, While I was at wot I looked at my boost gauge and it was at 30. I dont wont to hurt anything in the motor or tranny. I will be looking at the 7.1 conversion within the next year!!

Thanks Kyle

I dont think 30 lbs of boost will hurt anything in the motor but you might want to keep an eye on your stock turbo if your running a stocker. I dont think 30 should be a big worry but just in case.

Whos smoke tune are you running? Twisters? Like the smoke? :lol:
30psi isnt even where the turbo becomes inefficient. i run 36psi on a race tune without problems.

Stock charger is fine.

isnt the twins out here pushing 50psi on stock motors?
im sure your fine for the motor, the trans is questionable

My Stock Turbo hits 34 regularly.. thats PPE tuning.. No problems here:thumb:

[madmaxdmax]

My stock LB7 turbo hits 32 on a regular basis....so far...no problems !!

But those are very different then the VVT's.

[DIXIELAND DIESELS]

Yes it is twisters tune!!! I do like the smoke, I am in need of the trans go-jr to get the full effect of the smoke part. It smokes pretty good 1-4 gears, have the tranny locked in 4th. I still havent hit WOT with it until I upgrade the Tranny.

[big block 88]

30-35 pretty regularly no problems yet

[silverdmax]

i hit over 35lbs of boost with my ppe standard on setting #4.

[x Madmax Diesel]

I wish I could get 30 psi. Mine spikes at 28 on my big tune

[silverdmax]

i had to trade in my 35lb gauge in for a 60lbs because i would barey the neddle

[Royce]

isnt that twister smoke tune danger danger on the injectors???

[durafarmin]

Ive hit 50 lbs, most stay below 38 lbs to be safe

[MadMaxx61]

Stock LMM turbo Have hit 45lbs but that was not what I was trying for lol

I have been running about max of 38-40 for over a year now.

[silverdmax]

does anyone know if my truck is building too much boost for what im running. i have it set on ppe standard 4 and my ppe boost builder is off and i am making over 36lbs of boost and sometimes even 39lbs. i could use a little help:thumb:

[silverdmax]

any :(

[Mike]

What is your drive pressure?

[silverdmax]

im not sure

[Nemo]

I had 33ish on a PPE Hot+2 E.T

[silverdmax]

i know its awsome to have all that boost but other than detuning it how could i turn down the boost.

[tinman22]

I dont know about anyone else but I have ran 31 to 33 psi for atleast 75K miles. I have over 104K on the truck now. from what I have read anything over that is putting the turbo out of its map range and you are just making higher egts and not seeing anymore power from the turbo just heat. I have had mine hit 45 psi... once. that tune was then removed lol. as for getting the boost pressure down. perhaps you need to lower vane position and commanded boost levels with efi live or some tool like that.

[Mike]

don't put your foot in it so far ):h

[silverdmax]

i found the problem... or was it. the boost builder. i unplugged the boost builder and bingo the boost sat at 32 wot the whole time.

Whats a boost builder?

[silverdmax]

its a product from ppe that lets you build up your boost when towing with a dial and a toggle to turn it off so it only work when your over 18lbs of boost.

[x Madmax Diesel]

Ohh okay, gotcha. I was confused with the terminology. I'll have to hook my old one up and see if I can get 45 too.

[silverdmax]

i dont think you will get over 45 but i think you will like it if your over 35lbs. i have my ppe setting 4.

[silverdmax]

so i put my dmax back too stock and had p0299 dtc come up. just wonder why that would of happened.:(

[silverdmax]

what boost levels have any of the guys on here with race evolution hit

[OTHRGRL]

Most guys with the race evolution are going to be using it for gauges as well, which will mean they are reading boost off the stock sensor - which is normally off and/or limited to a certain amount.
