My 1.6TD Compound Turbo is up and running, 30psi of boost in neutral!

Anyone seen the movie "The Pinchcliffe Grand Prix"?

Short video from me. Not from the track, but som testing in the middle of the event

This is awesome Scaring the sheit out of drivers behind you because they cannot see through smoke
and when it clears- you are gone   

I find it interesting that you even have smoke at such boost levels   
Your injectors are stock GTD I quess?
What is your max EGT you saw on this setup?
I always wondered what is the limit with IDI diesel with your headwork, valves and everything..
I believe you achieved it 

What is you tire brand and tire size? I plan on federal rsr 195/50 but your look like more ''meat'' and different profile...
Almost drag racing-fat haha loving it!

Keep up great work!

185/60-13 Yokohama A048  track/competition tires Wanted to keep the 80s look on the car. Pump delievers a ***load of fuel, will up the boost soon

[Alcaid]

Fratelli Bosio GTD nozzles on AAZ two stage injectors. Didn't have time to hook up the EGT gauge so will have to check that in the dyno. But it's easy to cool down the EGT with addee boost if needed since I am running compounds.

Holy crap, that's awesome. 

Fantastic job, Petter. 

[RabbitJockey]

it is truly impressive, if it can dyno the 300whp that is like a 5.9L cummins turbo diesel making well over 1000hp

Wow I never knew they let freight trains run on the track, because that thing HAULS!!  What an amazing setup.  I've never seen an IDI this massively built before.  I've seen some great high-flow single turbos (shout-out to theman53!), but no one runs compound around here outside of trucks.

On another note, Rudskogen looks like a very fun track!  I've heard it from mentions of the motorsport event Gatebil.  How is driving on it?

That's nuts Alcaid - I didn't know a turbo could even boost at idle.
Still loving my Holset

Rudskogen is a demanding track for both car and driver. You need lots of HP to drive fast, lots of guts to brake late even approaching blind turns and a challenging track, but it is very fun! I am more comfortable in my Golf 4Motion PD130 (now 191awhp) on tracks so need to drive more with this Jetta to get comfortable with FWD, lower weight, no power steering, poor brake assist etc. etc.

What's better than a Holset, right? (The answer is TWO Holsets!)

Long time no update on this project as I got really sick and tired of it....

I initially had some head studs made from the Finnish guy that calls himself AKI-76. They stretched and all came loose on initial test driving... Tried to re-torque and they started stretching  real bad and one broke.... Tried saving the head gasket by changing out one and one stud with ARP but gasked was blown. Later I changed the head gasket but was still blowing coolant out of the expansion tank (running 60psi of boost on the last tests with great power and low back pressure!). Took a long break from the project as I was really sick and tired of it....

Finally got the interest to continue the project and took the head of again to pressure test it and resurface if necessary. Head was warped on cylinder #2 and #3 so really in need of a resurfacing. Will get the engine back together again soon and do further testing on 60psi of boost.

Pic showing the head after the first pass, easy to see why I had coolant blowing out of the expansion tank!



finally head is flat again!

 Do you line bore the cam when you surface the block?
Center journals are going to be high and make the cam teeter totter.

Not done anything to them, not had to do that before either when surfacing a head...

[RabbitJockey]

any opinion about resurfacing with the prechambers still in place?

[ORCoaster]

I thought it weird.  But apparently it didn't do they any harm.  Just a few thousands less for wear.   I wouldn't expect a problem unless they were loosened in the process and not tapped tight to prevent being blown out now.
