    5th gear isnt that weak, 30hp should be more than ok

    Garret gt 3788r drive pressure

    Ok yeah,could easily be. So u keep the ratio around 1 to 1 up to 60 psi? Wow, guess i should consider twins

    Garret gt 3788r drive pressure

    Got it from the tial sport stand at schied diesel.. so apparently they sell and modify garrets. Yeah the discharge fit the stock lb7 boost tube. Give tial a call, see what they say. Once ur big charger starts moving air, it d be ur exhaust wheel and housing restricting right?

    Garret gt 3788r drive pressure

    Ok yeah it works best if u dont push much over 30.. its great for a mild turbo upgrade but not if u shooting for 700 hp

    Garret gt 3788r drive pressure

    Yeah i know. Mine was worked over and fitted with that wheel, we measured it, yeah i wish it had the 4088 turbine, i think the compressor is that big that the turbine doesnt have enough power to turn it without making high back pressure, it spools pretty good tho

    Garret gt 3788r drive pressure

    Its the .99 a/r gated but it wasnt hooked up, with the gate operating it dropped boost to 28 lbs but drive was more like 45-50 psi, guess i was hoping for little more boost but it ll have to wait till i upgrade

    Garret gt 3788r drive pressure

    So the garret ball bearing turbo on my lb7 seems to have high drive pressure. 65-70 psi on 32-34 pounds of boost. It has 68mm compressor inducer on the 72 mm turbine, which i'm finding out is stock lly turbine size. Anybody else have drive/boost ratios on s366s, variable turbos, or s400s. Thanks

    biggest nozzles on stock injectors?

    I think to guys should be quicker to pull their injectors and screw bigger nozzles on.. not that expensive and pretty easy to do

    03 duramax lb7 smoming at idle. Looking for answers

    Yeah,and if the truck started hard u might have high return rates, but if it popped right off then its probably just nozzles.

    03 duramax lb7 smoming at idle. Looking for answers

    Run ur truck with the valve covers and return lines removed..obviously u have to put high pressure lines back on.. see which if any injector returns a lot of fuel, the return should just kinda bubble a little fuel, not a teaspoon per pulse lol.. if any leak alot, replace with bosch reman and...
