Boost controller questions

[Cuppa]

From another thread:


Hi Nev, I can highly recommend Chris Dalton from Dalton Engineering in Wood St South Geelong to tune your TD42T, he is a great guy and will get a great result for you. tell him what you want and he will get it for you. Very well priced and an honest Tune. Make sure you have fitted you manual Boost COntroller before you go there and he will sort it out for you.

This is advice I intend to follow, Geelong is much closer & easier to access than Lilydale.
I’ve had a squiz on eBay & see that manual boost controllers vary in price from around $25 up to around $300. I note MR’s recommendation that one be fitted before going to Chris Dalton but never having come across these things before I have some questions.

1. What is a good boost controller to buy for the TD42i? Recommendations please.

2. Why the huge variation in price. What does paying more get you?

3. How do they work. I can see how they could restrict boost, but how can they increase it? Is there some sort of factory ‘controller’which it replaces?

4. Where would you fit one on a TD42i? (Pics?)

5. Would it be best for me to fit it, or take it to Chris Dalton & him to fit it as part of the tune. If I were to fit it can I do damage by not having the boost set correctly. How would I ensure the motor retained it’s current boost prior to getting it tuned in Geelong?

Ill have a crack at this but please correct me if I'm wrong anyone...

1) turbo smart

2) reliability and better control?

3) they increase boost by holding back the pressure before it releases to the wastegate.

4) connection to the pipe that goes to the wastegate and the control is usually just zip tied up higher on the engine bay wall usually to another hose or component.

5) very easy to install but just get him to do it whilst getting the tune.

1. I like the turbosmart manual controllers. They are easy to fit and easy to adjust. They are normally aroud the $100 mark. They are very well made.

2. Some will do their job better than others, ease of adjustment etc etc all comes into the cost side of it. The turbosmart ones are Australian made.

3. The alter the pressure the waste gate sees this in turn regulates your boost.

4. You will need some hose. The controller goes in the hose that is on the compressor of your turbo.

5. No damage can be done. As far as I'm aware the waste gate will determine your base setting the controller can only increase this.

Cuppa I sell a boost controller thats about in the middle price wise. They are made from the same bloke who makes the Dawes valves for the 3Ltrs, Darren Dawes in the USA. Except this unit is designed for the TD's and alike. I have sold few valves to Chris Dalton so he does know his stuff. So you will be going to the right person.....Just putting it out there.
