Diesel Wastegate Creep

First of all, i´d like to congratulate your excellent magazine and articles, specially DIY Tech Features. I´d like to know what do you think of attempting the Killing Wastegate Creep project on a turbo diesel without electronic boost control.

Telmo Brandão


The speed with which a turbo diesel comes up on boost is often more related to fuelling than wastegate control. That said, it is certainly worth trying the ‘killing wastegate creep’ approach.

I like you site and have used it as referances for many of my experiments. Although no one told me about this one until after my very expensive manufacturing and mucking about with making my own... Cool Stuff - Manifold Insulators

Cheers ears...

Light-Weight HPV

I really liked your article covering the ultra light-weight car that the UniSA students are building (starts at Building an Ultra Light-Weight Car, Part 1). This kind of information is exactly what I like to get, so please keep up the good work.

The method of construction is very interesting. Your article tells me that using a honeycomb core material may actually be feasible for a backyard DIY person. Previously, I had considered this material to be (financially) out of my reach.

Now here is a challenge for you: Combine the honeycomb material and the basic design of your latest HPV trike to make build number 4. The result would be a vehicle that is (partially) enclosed and may give less wind resistance. I think that one of the most difficult parts would be keeping the overall weight as low as your current steel tube design.

Again, please keep up the great articles.

Number 4 trike is currently under construction – and it uses chrome moly tube. However, we are closely watching the development of an ultra lightweight fairing that would suit such vehicles.

Bonnet Lift

Just had a quick question about the effectiveness of using washers to raise the rear of the bonnet. Does it increase cooling in the engine bay or is it all nonsense?

To be sure you’d need to do some testing. Based on the tests of pressures above and below bonnets that we have done, we’d guess it wouldn’t work. See Undertrays, Spoiler & Bonnet Vents, Part 2


Great magazine. I gave up reading car magazines 20 years ago but since discovering yours I visit it often.
