Opinions on TurboMaster Device?

[TStinson]

Has anyone tried this thing on a 24V?

The model24 is for 98. 5-02 model 24V engines.



Looks like a little extra boost (6-8psi) may be attainable over the boost elbow to allow burning more of the fuel available with larger injectors.

They have one seat-of-the-pants test done with a 24V 3500 5-spd pulling a load uphill that seems to show some real help in keeping EGT's down.

Turbo Master

I have one on my race truck that I intend to experiment with.



My concern is to set it up so it controls the primary turbo waste gate. The adjustibility is neat. I will be able to run one spring for straight fuel and a different spring when we use the Nos.

Does the Turbo Master replace the existing waste gate mechanical stuff (arm, etc)?



I have a used HX40 from a Volvo. It has the waste gate arm going in the wrong direction, and will need to be replaced. Would the Turbo Master do this?

I think all the HX40 16 cm housings are orientated this way. You need to grind the arm off and rotate it 90 degrees and weld it back on. This is what PDR does.

I will be sending the HX40 to Piers for mods. I spoke to him briefly, and unless my memory fails me, he said it would cost about $150 to replace the arm.



This HX40 has a 18 cm exhaust housing. I'm hoping it will not have too much lag.

Yup

The turbo master replaces the stock wastegate control. It's got oodles of adjustibility. Testing is now completed and they are tooling the new model 40. The production controller will be configured for single turbo applications.



I think you won't like that 18cm.

Here It Is

This is the 24v version

Here is the 12v version.

HVAC - Thanks for the pictures and the info. It appears it would be cheaper and more efficient to use the turbo master than modifying the stock unit.



As for the 16cm, I think you are right about my not liking it. Piers said he modifies them to make them more efficient. How much more efficient, I don't know. Probably have time to drink a cup of coffee while it spools up.



I am open for suggestions on the turbo. I am chasing EGT's. Obviously, one option is to try the 18cm simply because I already have it.



What would I be looking at to replace it?

Are you saying the TurboMaster products are better than a bleed elbow.

 

[Jetpilot]

The Turbo Master is better than a bleed elbow as it allows the user to adjust the boost levels for the individuality and best overall performance.

Reddog1, your welcome. Happy I am able to help. I do think the TM would be a good way for you to control the wastegate in liu of the stock wastegate.



Reddog1, if you double check you'll see my concern is over the 18cm housing. I ran the 16 and liked it.



JohnE, what Jet said. The TM has adjustibility which I like. I intend to run one spring for fuel only runs and a different spring for Nos runs. I expect the Nos to increase my boost pressure higher then I would prefer and I expect the TM to provide a nice way to compensate for this.

How does it compare to the adjustable elbows?

I've got the elbow that came with my TST plate and I can adjust the boost from 20 something psi to 40+ psi.

Does the TurboMaster do something different than the adjustable elbow?

Bleed elbows dump overboard don't they?

HVAC, A "Turbo's for Dummies" question: Why would you want to control the amount of boost? I thought more boost meant cooler temps.



I'm running DD2's and a Comp box. How is (and would) the TM adjustability (be) an advantage to a typical set up?



Thanks for any info.

Walker,

The wastegate on your truck is set to open and bypass air around the turbine at 20psi of boost. Wastegating allows the use of a smaller turbine wheel to aid spool up (dreaded turbo lag) but a smaller turbine wheel will overspeed at higher boost pressure/flow rates so the wastegate maintains is used to control this situation. By altering the pressure at which the wastegate opens you can increase the pressure & density of the incoming air and thus introduce more fuel for more power. With your set-up aren't you smoking like a madman? On the 24V trucks you have to do two things to increase boost. 1. Install a boost elbow/turbomaster/turnbuckle/regulator or something else to physically change the point at which the wastegate opens. 2. Install a boost fooler of some sort to 'trick' the MAP sensor from setting an overboost code and defueling at/above 20psi. Most of the boost foolers are a simple circuit that 'clips' the voltage from the MAP sensor at the 20psi value.



Hope that helps,

Brian

 

[Walker]

NVR, Thanks for the schoolin'. I think I understand it a little better.



I do have the boost elbow with the box (which has the boost fooler in it). And I really don't smoke to bad until I romp on it at level 3x5 or above.



So, is the TM product something I would benefit from 1. Power wise. 2. Smoke wise. 3. EGT wise. ???



Always lookin for another pony or two.

Other than adjustability with different springs for the use of "drugs" on the truck, is there any benefit of the Turbo Master over the TST Boost elbow on the 12v trucks?



Would the spring "wear" over time needing readjustment? Not that it is a big deal, but it seems that it is entirely possible.
