Had a go in a 16v Mk1

Wouldn't we all love a force fed mk1,LSD,4wdisc :!: :!:
I go to sleep every night thinking about how cool that would be...if i won the lotto that is lol.
And i've got somewhere information telling me that the K-jet injection will max out at 220 hp as the pump might be able to feed the fuel but the air flow meter will top out when the air pressure builds to it's max cap.
There's a guy up here in QLD that had rebuilt the gti 8v that was in my mk1 when i bought it, I had got intouch with him and he seemed to know all the ins and outs of turboing a mk1 with k-jet said he had a secret but wouldn't tell me.
But i do know if you hook up your cold start injector with your full throttle switch you can add that little bit more fuel at full throttle suppose to add a little power apparently.

Yes many people say the K-jet has a theoretical limit and with smaller the airflow meters thats true, but they did use K-jet on turbo porsches and the old school euro racers, I think even F1 used it at one point. The beauty of the system is you can interchange parts from other cars with a little ingenuity, for example if you wanted to you could fit a 6 cylinder airflow meter and plumb in 2 extra injectors at the top of the inlet manifold etc., imagine using one of a V8 mercedes :twisted:.
As for the cold start injector on at full throttle, I think that might be possible on the KE-Jet cars that have lots of other electrical imputs(exhaust gas analyser etc.) to the computer that can adjust the fueling back to a safe level. But on a standard K-jet it would just waste fuel and give a bad mix, as they run a tiny bit too much fuel as standard, I know mine drops a little bit of black smoke(unburnt fuel) at high revs and is standard.
One trick when turboing a K-jet is to use a WUR(warm up regulator from a turbo car) from an Audi etc. as they have a boost input tube that u run off the manifold and it increased te fuel that way(one of many). Also a rising rate fuel pressure regulator would be good but haven't seen them on the market for K-jet(extemely high pressures compared to EFI) for ages.

G60JAY has a 16VG60 Syncro Corrado in Brisbane.

More than one G60

and a pretty special one at that.

A mate of mine has a 2.1 16V MK1 running Webers. 210 at the crank. He uses it for trackdays mainly, the acceleration is unbelieveable. At the track he sits on the back of the 911s until they give up trying to stay in front of him. From the side of the track you can see the Porsche drivers staring at the rearview mirror down the straights.

He has Yokohama 032Rs the barely legal road tyres, fantastic amount of grip.

A mk1 16V is a formidable car, for very little money, in Europe anyway.

FANTASTIC. I want my car back together. By Christmas hopefully.
I reckon itd be formidable in Oz too, you surprise people in a 1.8 Mk1 8v. 16v will be a lot of fun. Cant wait.
