I'll be getting DP Engine parts conrods for my 07k when I do my mild build. The worlds fastest 2.5l 5 cyl uses their engine parts.
How much are the parts you're getting from them?
I read that you might be able to tell whether you have a forged crank if the flywheel mating surface has a number that looks like 07k101e. Hank Iroz over at Iroz Motorsport knows a ton of information about the 07k and other VAG motors. There are others on 07k Facebook group that have valuable info as well. I’m still gathering parts, researching, & learning as I go. I’m planning a motor build with upgraded block & head internals. Some have said it isn’t necessary to upgrade internals unless your goals are above 400whp. My goals aren’t above 400whp but I figured just to be safe & do it now as I could always change that goal. Apparently cast cranks have no problem supporting up to 500whp.
When i was getting my UM tune on my car, the boost reference line to the wastegate melted and the engine spiked to 14psi. Fred at United Motorsports said that it was starting to pull timing due to knock and that is bad for stock internals. It was a super hot day that day and they were road logging then letting it heatsoak instead of a cooldown drive.
Apparently these pistons dont like knock at all and are prone to failure if they do. Although, i've seen some guys on instagram running UM tunes to 20psi on stock internals and not blowing anything up.
I guess the real question is who has found the limits? Boost pressure is only one aspect as turbo sizing plays into how it hits and how the engine holds the pressures.
I plan on running run it to 12psi and put 94 in and log it to see what the timing pull is if any. That should net me about 350ish which is enough until i find a wrecker engine to drop rods in. It'd be nice to have a mild 500hp build with safe internals.
