Definitely swap that intake for an FSWerks unit. The k&n has been know to completely skew AFR and the piping is way too small to take advantage of the potent flow characteristics of the 2.3.
The 3inch intake with shrunk maf housing of the FSWerks is what gives proper velocity over a 2inch full diameter straw.
You did explain it, it's just not correct.
I meant 2.5inch not 2inch.
These engines like the breathe. And yes, the 'shrunk' MAF housing I was referring to was simply the same size piping as stock at the maf(which is what yours is, only everywhere).
It doesn't create velocity, it's a straw. It will gain power because it flows better than stock, you will, however, lose power over nearly every other intake available.
A 3inch intake(FSWerks for one piece like your K&N, CFM or a Cosworth) with factory sized MAF will create more power and torque everywhere.
No need to argue, your logic is just incorrect with this particular part. Everything else seems to be in check.
There is plenty of proof out there already of what I am discussing. This combination has been tested a few times over the last 11 years.
One of which I personally dealt with;
We had a local with a fully bolted on 2.3(stock intake manifold) stuck at 139whp/135wtq on a dynojet. Unhappy with the numbers, the owner asked for ideas, we swapped it's K&N intake for a Marcy Motorsports(4inch into stock MAF housing into 3inch throttle body pipe) another local had installed in his car and the next immediate dyno was 156whp/159wtq.
He bought his own the next business day. That was a car with programming btw.
I'll try and dig up the thread, it was about 8 years ago.
I look forward to your dynos. I hope you understand I'm just trying to help you make your car better. I really do love builds like this.
There is a reason why the people most familiar with the focus(not K&N) use larger piping.
when it comes down to it, the proof will be in the dyno charts.
Lots to catch up on, including the SCCA Solo Nationals and ProSolo Finale, but for now... a video of my time-attack run at Brainerd Int'l Raceway during last weekend's MAPerformance Proving Grounds event. Got a little "slideways" at Turn 3, (47-second mark.)
Thought I saw an SVT there. How'd it go for you? I was entered in the Triple Track Showdown (drag, autox, time attack) and it was a lot of fun!I was at this event with COSVT… saw your Focus sitting next to the auto-x event!
I can. I used to run a Schroth in my old car, but I've gotten a little crazy with weight-savings this year. Lots of improvements planned for the off-season. We'll see if a harness makes the cut.Looks like a ton of fun. Can u within your rules set run a 5 point harness or a schroth (sp) harness, u will go faster held better in the seat.
