STAGE 2??

[topher]

if you have a good turbo and no leaks you should see more than 240lbft with stage 2 really

imo the entire stock exhaust system is a restriction, but if you're being picky about things the standard exhaust manifold is even worse.

i love my fmic in this weather, i did 250 miles today and heatsoak wasn't an issue once!

..i realise that probably hasn't helped the original question i would say you need to do everything, doesn't have to be all at once but what's the point in going stage 2 if you can't use the power all the time?

Up to you if you think it's worth it though, save a grand by not fitting a turbo back? Maybe just get a custom down pipe as that's apparently where the restriction is. 240bhp from a ko3s at 16 psi, how did you get that figure, dyno machine?  A ma on the Audi forum was running mega high boost of 24psi with 230bhp, but 290lb torque, he did turn it down for his turbos sake, most agreed real figures for stage two are around 225bhp with 240lb.

Downpipe will aid in spool, biggest restriction will be the cat itself more than the actual exhuast or downpipe.

Plus all the IC talk, a tall IC like the rad unit itself will probably be best for maximum airflow even in traffic especially when the fan kicks in on the rad, but if you hav AC pushing the rad back will be harder, due to the space under that bonnet. I know toyosport do a A4 IC which is only 50mm deep and a nice size if you want to push the rad back to fit it in, that's my plan.

runs aftermarket ecu and have two dyno prints out.

have you logged it ? to see what airflow your getting? Dynos arn't accurate now are they.

dont have evidence of the boost levels, just what the engineering company that tuned the ecu told me it is running at. Will be fitting a boost gauge soon to keep an eye on it.

cant log it as i dont have the software or cable yet.
