Understand your point and I was answering the posts/questions about whether or not the OP had done the dyno work....I would have to go back and look at my dyno sheet to see what the AFR was.

I have said it before, there is only so much power that is going to be gained on a NA 4cyl 2.0L engine....the ST is a perfect example; gaining 90 hp with 19-20lbs of boost is not that impressive.

The heat soak discussion has been around since aftermarket companies have constructed intakes and I don't think there has been that much if any temperature differences between IAT's on plastic/metal intakes.

If I could afford it I would love to see an intake shootout via a dyno, same day, same conditions, etc....you see this in the mustang and larger markets but unfortunatley we will never see it on the Focus as it is just not that large of a market and will not get the exposure that the other brands/lines do.

That thing looks a lot better than the stock air box.

Actually in the case of the ST; gaining 90hp with 20lbs of boost running 87 octane is extremely impressive. It is a damn amazing trick. Clearly you've never seen a turbo'd engine blowup from insufficient octane.

The fact that its tuned to run 19-20lbs of boost on 87octane means that with some plumbing upgrades (like downpipe and catback) and tuned for 94 octane some truely impressive numbers are possible.

Maybe your just not easily impressed.

Sorry; I am in the mustang community as well and I am just not impressed with 20psi=90hp...guess we will agree to disagree on this....and if you use 87 you lose 9 hp so my ratio is even worse, 20 psi=83 hp.

83hp more hp and your engine still doesnt blowup on 87 octane.

I will concede that in terms of cost benifit ratio 20psi to get 83hp gives a feeling of something lacking.

Having said that; in your mustang community how many people with forced induction (turbo kit or supercharged) run 87 octane?

My experience with forced induction is from WRX's and STI's.

Properly tuned its reasonable to get roughtly 15hp per 1psi over factory boost with supporting upgrades (plumbing, FMIC) tuning and specific high octane fuel in a subaru. So yeah 20psi and 83HP sucks. BUT on 87 octane it is actually quite amazing.

If you wanna discuss forced induction at length and the HP wars go start another thread... This one is starting to veer off topic. Injen intake talk por favor

No one as that is just stupid....93 or above unless you are in CA where the max octane you can get is 91.

I understand why Ford has done this as they did it before on the 03/04 Cobra's to protect people from themselves as it has been proven time and time again how effin stupid people can be...have a 390hp car that clearly states 93 octane only yet Ford had to take into account the idiot who would put 87 in it, hop in the car and run 120 uphill in 5th gear.

I know people are impressed with the tune on the ST's but a lot of that is with using 93 octane which means you can add more timing which means a lot more power esp on a FI car.
