Hi man great achievement!!!! I have the same one, however having trouble with valve stem seals. Running cat cams 1002448 13.25/12.45 lift on valves. There's 2 mm seal clearance but the seals don't last, any advice?
500whp.net I only have a schim 0.5 mm thick under the springs. Guides are standard which pressed deep into the head. Base of the seals are flush with the spring seat. New seals leak within the first warm up cycle.
That's mental! boost seems to came soon! could you explain the exhaust system? big exit behing the front fender, but there's still an exit one the bumper?
i've seen plenty of cars with dump or screamer pipes. But that one is so big that i though that it was the exit from the turbine, not the bypass/wastegate exit
maybe that's not the screamer pipe itself coz that's moving like the engine and can hit the fender. stock 44mm's enough around 600hp and that's 5 times bigger there :D
That's a 4,5" exit for the downpipe. There's a plneumatically controlled butterfly flap that opens at around 0,3bar boost. The single 60mm wastegate goes under the car with a screamer pipe. There's also a full 2,5" stainless exhaust parting from the downpipe which is used on normal driving. The 4,5" pipe has some flex joints in it, so the exit is stationary to the car while the engine can still move a bit, which it really doesn't that much as I have billet engine mounts with very hard rubber dampers.
+500whp.net very nice, that will be my next upgrade. I now run stock 7a cams. What turbo are you running? Im thinking of upgrading my tb60 to a 70 or 80mm turbo.
can't wait for more videos...such an epic car
Its an animal
Hi, what turbo? Holset HX 52 pro? Thanks, great numbers

I dont know, I hven't had any problems with valve stem seals! What do you have under the springs? Which valve guides do you have?

nice, how many rmp comes this turbo pressure?
You can see the RPM in the screen. It's the middle number. Turbo spools at around 6000rpm.
Hi man, i just bought myself an Audi S4, could you please tell me all the engine mods you did. Thanks
Everything.
Hey cameron, just checking in to see if you have done "Everything" as well?
Impressive! High Flow head and good cams? Usually more boost is required to achive those figures :)
310hp intake and 250hp exhaust flow. Cams are 13,25mm/11,45mm / 289/279deg 0,1mm / 255/238deg 1,0mm.

I run a custom 72mm billet holset.
