I have recently purchased my first diesel, a 2001 cummins and have installed a power programmer stage 3.  I have since been looking for a quick and inexpensive fix for turbo lag.  Here is a product that I found and was wondering if this could or would be an option for me or anyone for that matter.  Thx for your time...

There is no such fix. That is the downfall to a turbo. You need RPMs to get the turbo to build boost.

i am in the same boat i just put on a 120hp chip and there is alot of turbo lag. i switched to a hx35 hybrid, that helped some but there is still lag. i am thinking about a small 30 or 50 shot of nitrous oxide to add air, lower egt and intake temp and reduce turbo lag. it is cheaper than a new turbo and you can turn it on or off with the filp of a switch. and last make sure your exhaust can flow freely a 4 inch turbo back exhaust will also help, but they say bigger is better. best of luck to you. keep that CTD rollin.

Have you guys thought you may be lowering your drive pressures because of to much fuel to quickly?

Piers and I had a nice long discussion about this a few years ago at the last Thunder in Muncie event.  If you haven't heard of Piers or TiM, it's a long story.

Regardless....Try not just flat footing it, try easing into the throttle.  Try counting; one thousand-one-one thousand, before your foot hits wide open.  You may be amaized at how much more quickly you build boost.

Turbo lag is part of the game. Two foot your rig to get some boost up, then nail it like a prom queen! With the exception of level 4 and 5, two footing it is the only way to get it spooled up without too much lag.

Two footing the turbo does help spool. But, keep an eye on your Tranz temp. It can sky rocket in a of seconds when you power break it. The best way to "limit" your spool. it to change turbine efficiency. On the Hx35's you are limited to about 3 or 4 turbine Hsg wile keeping the HX35 turbine wheel. The 12cm,14cm,16cm,18.5cm. The smaller the faster they spool.

    The 12cm will have the fastest spool and the highest boost level. But, it can make your EGT's go up too, with drive pressure. On a street truck its no to bad, with a good wastegate to bleed off the drive pressure.

I wouldn't recommend a 12cm with a hybrid though(hx35/40). You will probably run into compressor surge with the hx40 comp wheel. You may snap the quill shaft doing that.  You need to step up to the 14cm or even a 16cm. I have found when I clip the turbine wheels there is still better response then running a larger turbine Hsg.  It seems to be more effective in droping EGT's.

The full Hx40 is usually a dog with the limited turbine Hsg's availability. To solve all your problems just slap about 150hp injector with an S300G and a 4in exhaust.  It's a perfect street setup.  Hope that help guys.

A VGT turbo will cure all trace of turbo lag.

Hey a good cost effective way to reduce turbo lag and increase spool up time is to get a turbo wrap/cover. You can find them on ebay for under $50 this will help response time and improve heat transfer

A turbo wrap has zero effect on turbo lag. When the turbo is spooling there is low energy in the exhaust, its basically little more than a paddle wheel.

Wraps are only to reduce engine bay temperatures (radiant heat). They have no effect on engine operation.

Hey Matt,

You can fix it or minimize it in different way. First one can be to install lighter turbo parts. A lighter fan will spin up faster, making the extra horsepower available more quickly. You can replace any of the turbo's rotating parts with lighter ones to decrease turbo lag. Ceramic parts are usually a good choice.

Second one cab be Install a smaller turbo. Smaller turbos have lighter parts to begin with, so they don't take as long to spin up. A smaller turbo won't provide as much of a horsepower boost as a large one, but the power will be available quicker. You can also fix it by install sequential turbochargers & intercooler.

Also can be done by replace the turbo's turbine shaft bearings. Most turbos have fluid bearings, which support the turbine shaft with a layer of lubricant sealed between it and its housing. Replacing them wihe turbine shaft, reducing turbo lag. For more details please feel free to visit us at idaho falls diesel repair shop

"Ceramic parts are usually a good choice."
False. Ceramic turbos cannot handle the stress of diesel engines. Ask anyone with a Series 50 or 60 Detroit.

"You can also fix it by install sequential turbochargers"
Sequential turbos cannot be installed aftermerket. Sequential turbos require computer control to operate the changeover. Such complication is beyond any DIY modifier.
