Top RB20 Club... do you have over 260rwkw?

[Dale FZ1]

On a 2 litre, yes.  Listen to Roy.

TD06H offers a fair bit more turbine flow than the TDO6S or TD06SL2.  Impeller sizes are roughly 67, 64, 61mm.  The bigger impellers will require more gas flow to get them accelerating.

I know the longer runners on the standard manifold work great for a street car with torque lower down being better, But I was hoping for slightly better response from shorter ic piping and lower temps as it is a track only car.

and it makes everything so much easier to work on.

I assume the TD06H is a no go due to response?

What DaleFZ1 said. With a small pot 6 cylinder you dont need the TD06H turbine flow to max out the 20G compressor.

 

I hear you re ther inlet manifold, I ran a Plazmaman and it made more power longer up top but that was over 7,000rpm or something. So is a little disingeinous for me to say it 40rwkws more at 8,000rpm. But it did....but also cost 25-30rwks through the mid

 

Strangely the car lost top speed down the straight at PI as it smply didnt have the pull in top of 5th even though i was raping it hard into 8,000rpm in 4th before shifting. I was frustrated as the car struggled to pass a 135i with exhaust as according to data i lost a bit on the straight and a few corner exits but gained at a few others. If I had my time again I would go std...which funnily enough my current motor has RB20 architecture and I now run std inlet
