Lets think bigger turbos!

[Mante]

What is the top speed you've acheived?

I keep getting it mixed up with another vehicle its either 186 or 183 mph.. done in a controlled environment.

[Nutter_John]

At what revs are you hitting that speed Mante ?

[Mante]

I have no idea, I do know I ran out of gear

[bradc]

Thats about 7800-8000rpm or so from memory.

Just a small update.

My "former" car was finally put on the dyno by its new owners... 455bhp at 1.4 bars. Still on stock internals. I think its still capable of more boost, but seen as some people were bending their rods due to knocking (at 507bhp level - car made by other vr-4.ru member) I guess the stock internals can hold the power fine for up to ~ 450-470bhp if everything esle is right (parts&tune)... the first thing to upgrade after that are rods.

[bradc]

Is that 450hp at the wheels?

[valmes]

No Brad, its crank power.

[zentac]

its not that standard rods wont make the power, its how long they will last at that power, mine lasted 12 months before it put a rod out the side of the block.

They only recommend standard EVO rods up to 400-450 flywheel, and they are a lot meatier than standard VR4 rods.

and you don't bend rods due to knock, you bend them due to excess pressure. There was no knock what so ever on my engine.

[bradc]

That is 100-115hp per rod in an evo though and 75hp or so in ours.

[Nutter_John]

The vr4 produces a lot more torque than an evo so your looking more like 370ft/lbs for the evo and Gowf made 500ft/lbs on his 450 bhp , so thats 83 ft/lbs for the vr4 versus 92 on the evo so it's very close
