so.. in a few weeks... :) |
was out for a ride yesterday for the first time.. boosting 22psi and it hits you pretty damn good... i had to add ~5% of fuel on top now with the 4" exhaust and new ic piping.
a big package is waiting for me at the postal office... will pick it up tomorrow... thanks enzo :) |
Sure.. NP..
Make sure you have a good breakfast that's a heavy box.. :) |
Carnage!
YES!
have been running the car on the street for a couple of weeks with NO issues at all at 22psi.... got the car to the dyno tonight and did a reference pull to see where i was at.. didn't pay that much attention to boost since i was running the same setup as before, no changes.. all of a sudden boost is at 40psi at 5500rpm :dunno::dunno: the wastegates just didn't want to open!!!! :shocking::wallbash::burn::greenchai:Kill2: now i got a big crack in my front iron and i lost 4 litres of oil that is now lying all over my engine bay.. :icon_no2::icon_no2: saturday im taking everything apart to see if theres anything i can reuse.. :lol: ill throw in some pictures for ya when i got them.. no track for me this sunday.... http://transport.molnsatra.se/bil/graph.jpg |
Ahh that sucks. What happened with the wastegate???? What kind is it...looks like the valve maybe stuck on the gate. I assume this is still the unit you got from my buddies at F.I.?? Are you sure you had the wastegate referenced to the bottom port and not the top port only??
|
sorry to hear that Gus hope you get it sorted.

it's funny you can lose attention just for one second and that is what it takes to blow everything to pieces. Im not giving up... i think ill upgrade a few things :rolleyes: im actually pretty excited to see how she looks inside right now :lol: |
So, you put down 770 hp before it cracked? Did the seals even break?

344hp at 5335rpm. The motor still ran on both rotors but no oil pressure.. and no water left.. |

nah thats the boost curve:lol:

This helps me though, since it's a somber reminder for me to establish an ignition/fuel cut above my target boost pressure... What kind of apex seals are you running? I'd love to find out if they stayed intact... |
Thats kinda wierd. I was at the drag strip last weekend. Got home swaped maps and fuels. Went for a ride the next day and the gate was not opening at all. I hit 1.38 bars! Thanks god a had a mix of fuel in the tank. I may go back to a proven Tial.... Sorry to here about the motor..

damn... never seen a motor plate broke in half!
|
Gus that front plate looks like it was counter-bored for 5 studs. In the pictures the crack runs through bored steps. :scratch:
What is the history of that plate? Barry

Gus were you using the dowels on this build?
You have the housings reversed in the picture of the loose stack. The bores in the housings are hard to see in that area and you have regular bolts pictured in the rear plate. Also were the apex seals flattened at all on the center of their faces where they cross the spark plug holes? Barry

Gus, your English is perfect! I can only imagine speaking as many languages as you speak.
