I'm in the process of building a k-jet turbo mk1 & have been gathering part's over a period of time. The car already has a Volvo 240 fuel dizzy & airflap assembly. I've also added in a permanent fuel pressure tester incl. a tap to test both the control & system pressures.
So far, I've got a saab T3 turbo, Mitubishi Galant turbo intercooler, audi turbo warm up reg, dual port dizzy assembly & a few other bit's incl. a callaway boost gauge & other bit's & pieces & also waiting on the rest of the conversion part's to arrive incl. manifold & A/F meter etc.
While waiting for these part's I decided to play around with some item's & tested the dizzy advance/retard pot.
I modified the pot & drilled out the retard stop & tested it. Under 10-15psi it didn't retard the ignition at all. At 20psi it retarded the ignition only a few degrees. Vacuum advance operated as normal.
I also fitted the audi warm up reg & tested it too. At hot idle without the vacuum hose fitted it would read 45psi (normal). As soon as I put the hose from the warm up reg barbed fitting to the throttle body full vacuum port it would run like a bag of crap & pull it down to 20-25psi! Even on the throttle body ported vacuum it would idle fine at 45psi, but as soon as you crack the throttle open alittle bit to pull vacuum it would again run bad & pull it down to 20-25psi!
If someone could please help, where about's do you plug the warm up reg. vacuum/boost reference into. Eg. throttle body ports, intake manifold to get the boost enrichment?
Also has anyone actually tested there ignition boost retard, as I'm interested in your result's to see if they actually do work.
What would be the approx power output of a k-jet turbo setup like this running 10psi?
