AGU engine build for hybrid - The great rod debate!!!?

depending on how hard you push them... but the 300 number is pegged at that level for a reason

The k300 has been pushed to 362hp on the dyno.
Stupidly high exhaust back pressures and EGT's no doubt.

The boost was pulled back and the car left the dyno with a safer 320hp.
 
John cobleys car. 362 was with NOS. Not as shocking as it initially appeared......

316 without gas. Very highly developed spec.

300 is the realistic limit on these. Hence the name.

Discuss what
The evidence is clear

Dont fit rods when chasing bigger power RISK them bending/breaking

Bill, when you say bigger power you're not referring to a nice stage 1 map from yourself are you? Standard rods ok with that?
 
no rods should have been done steve!!!
have they not been????

and I pushed the lupos K03 hybrid to 344bhp ... and the point?
None at all.. to brag about the figure? lol
Unsafe egt's /End But to test where the limits are........ so the "safe" IMHO levels are

the rest of the package make a huge difference to the end result. The turbos just one component not a magical bung it on and expect 300bhp device

sorry couldnt resist a tease!
steve its not a known situation fella as previously stated. people have bent rods on stage one yet some have gone big turbo and been fine.
if i was going stage 1 only id forget rods
stage 2 probably still chance it.
but that is only my opninion
definately not factual.
 
Thanks for the tease Daz & your opinion as well :thumbs up:

Thats why I mentioned it tongue in cheek. Nick made a bit more than that 3 years ago on his ko4 001 turbine and ko4 023 compressor with nitrous and WMI, running 12.6s in the quarter mile but it did melt a piston when WMI failed though, lol.
Interesting for academic reasons though.

Also why I started a new thread asking for opinions on the XSpower ko3 manifold.

Quite a few people got it tuned to 300hp, 300ft lbs if the rest of the hardware supports that.

The actual 41mm hole is the choke point.
There's not enough meat in a ko3 mani to port it anymore. They are already prone to cracking out towards the bolt holes (the thinnest point).

You can port the collector and clean up casting imperfections in the runners. Which helps reduce EGT's and might give an extra 10hp on the dyno.

Dan already ports the wastegate flap in the turbo hotside so thats done already.

Yea, I've ported the HELL out of my mani already... May not be the neatest job in the world but I've freed up a lot of space that's for sure:


In fact it could probably be considered a weight saving mod...

The neck of the hot side is the first bit to start glowing when being pushed, so guessing it's also a main restriction point... When I've got the engine out I may consider sending it off for porting and maybe get em to neaten up my butchered mani as well! lol
 
Firstly I'm a noob when it comes to vag but I have built some very high performance bm engines in the past which made think the con rods made for the s42/44 which was a track/rally engine used the same size ( not 100% about audi size as there's so many variations) con rods if you have the ones that took heavier duty thicker bearings big end bore is 49mm and 144mm long. I personally have used these rod on a 4pot n/a 2.1 m44 running 275bhp and 280+ft/lb torque, I also used them on a 6pot turbo build which used t72 ( omg they are huge and wouldn't even fit in an a3 engine bay) and they never failed it would be interesting to see if they fit in the bottom of an aug you would never have an issue with bent rods.
 
Must.

Not.

Shoot.

Down.

In.

Flames.

...or just buy a set of aftermarket rods that affectively just drop in and don't fail

Ironically the 20mm pinned rods are legacy of the VAG 16 valve engines as VAG are quite lazy

As a side note you may want to use a few paragraphs when you post dude... the above is very difficult to read and make sense off... I nearly binned you off as a spammer!

are you a noob to the English language also?

Quite frankly I gave up trying to translate it - was the general jist of it to use BMW rods in the 1.8T engine?

perhaps overly keen to win at the internet that day to worry about readability
