At 13psi and 2mmHG your effective compression ratio is only 18.5 or so. Based on that, your torque numbers down low seem to be correct. Right now my ECR is 18.6
Like it says above, you'll need to boost higher (like you are planning) and then hopefully there is enough of a flow gain to offset the extra heat due to adiabatic inefficiency.
It will be interesting to see what happens.

 

why not just do meth injection like s2kart? less money and less trouble.

just a thought.

 

Cant you upgrade to a 3071 thats internally gated on the greddy manifold? I know you can on the scion tc kit but Im not sure if thats possible on the s2k kit? If not what about a 20G? Is there a reason greddy made the dp so small, was it to mate to the stock exhaust ?

 

i think the DP is so small because greddy set out to make a carb certified kit, thus it had to mate to the cat..

there is a guy in the UK putting a 20G compressor wheel into the 18G housing; we'll see how it turns out..

do you think the 3071 would yield much benefit? i know my friend on stock compression and 7 lbs is getting about 360-375whp on a tubular manifold.. how much would you lose from going to a tubular to log manifold?

 

You would proably make like 295-310 on 7psi maybe

 

on the log manifold?

 

does greddy have any intentions to making any upgrades to the kit, such as a tubular manifold that doesn't crack, or possibly just a larger turbo/downpipe?

 

Doubtful, its a carb legal turbo kit. There is only so much you can do which is why, when you buy this kit, you must realize 300 IS the limit; nothing more.

 

well yes and no, they could offer upgrades with the explanation that it will void the "CARB Legalness" of the kit, can't they? Its not illegal to sell non-CARB legal products. I know you are going to say, "you'll end up spending as much money as if you went Inline Pro", but reality is with a larger Turbo/downpipe I would imagine its capable of close to 400WHP??????? again not stating this as a fact, more of a hypothetical/question.

Saying 300 is the ABSOLUTE LIMIT, well I would imagine its not, yeah its the limit "out of the box", however not with upgradeable parts...........

 

it's not ignorant; he's stating fact
