Accelerated Performances car. Supposedly they were able to get rid of the torque dip in the dyno curve. They haven't posted up the dyno results yet. Still tuning.

results were posted, 215hp at 4psi. thats 50hp over stock. I'm sure they will be able to improve on that just a bit with more tuning

roadrunnergt

Should do great with 8 pounds

Yeah 4psi and preliminary tuning. Not to shabby. Powerband dip was eliminated.

cessblood

They're still playing around with the fuel.
They sent some data to EcuTek.

rhythmnsmoke

Car still has the stock catted header in for these dyno numbers also.

GenomeTuning

That is very impressive for initial tuning, cant wait to see more ecu tuning

dropzone

Powerband dip eliminated is good news for sure. In for more vids.

subaru is going to change the design, to minimize this next run. that's the pics they posted in another forum.

Yup, after changing the pistons.

rhythmnsmoke

They are going to push it to 8lbs without pistons. Don't see any reason why it can't handle 8 either.

The S2k has a 12:1 ratio if I recall correctly. Boosting that on a stock motor and they are pushing 500whp on them. There is only one way to find out what an Fa20 will hold power wise on stock internals. 8lbs should be around the 270+whp mark I'm guessing.

If there are signs of detonation, there are still easier ways to push 8lbs without changing pistons...i.e. Methanol Injection.

4psi vs Stock

cessblood

Some people need to know this.

cessblood

S2k Compression ratio is 11.0:1 but I get your point.

roadrunnergt

The frs is direct injection along with 12:1 compression should be able to push 300hp with 8psi and a stock motor

Well my friend, there is possible and then there is practical. I'm talking reliable DD here, not a weekend racer where a blown engine is simply an opportunity to build the engine and raise the boost.

Fixed that for you.


"The more the compressor flows the less pressure required to attain a given horsepower."

That is somewhat misleading. It's the air temp that makes the difference, not the flow. The assumption here is that a higher flowing compressor will heat the air less, resulting in a denser air charge at a given pressure. Obviously there are many other variables to consider besides compressor flow and boost PSI.
