New Nozzles in the Tdi.....

Re: New Nozzles in the Tdi.....

Actually both would be best. The nitrous part of nitrous oxide is useless but the oxygen helps to burn the fuel cleaner etc, it really helps keep the smoke down with propane. Bart is right about the air part but there are ways to get around it by adjusting the IQ so there is less fuel. I think it is a little hard to measure nozel holes accuritly without special tools. I am sure if you bought them from Kerma that they will be .216's. You can find VNT-17 turbos on german ebay all the time for about $500 used of course. There is even a guy on the TID club that will recieve your package for you and reship it if the seller will not ship overseas.

Might want to wait and see if anyone can actually program an ECU to work with the higher boost from the VNT-17. Since the turbo is so similar to the stock TDI turbo (trust me there is not a huge difference) I think that only by increasing pressure quite a bit (and using an intercooler to keep the heat down) will you see big gains. Running a VNT-17 at the same pressure or even just a 1-2 PSI higher will probably not do anything. However, Bart tells me it is much heartier... if thats true then you can crank up the pressure to the limits of your internals, then put on a FMIC to drop the pressure a bit and increase the density.

.216"
Got them installed yesterday by Dave at DnF Motors... check him out on the board.
All I can say is Damn..... what a difference ...
Little Diesel rocket ...woooweee

Great work Dave
Thanks

Upsolute already has a map for it or *psst* rocketchip (sorry Simon).

yes for sure they are
offers?

Re: New Nozzles in the Tdi.....

Steve if you like we can play with the IQ. I bumped it up a slight bit it was running @ 3.0 mg/G I thought it was a tad lean. There really isn't too much to play with, it's a trial and error thing. Anyhoo, Let me know if you need anything else done. I'm swamped this week but next week is up for grabs.
