mmmm tonooorque

altho defifitely baselined lower than i thnught it would.


just to clarify, i'm discing the baseline, not the gains. I like the gahns.

I've seen several baseline at that...
FS's stock PZEV only made 126whp too!

Those are some of the best gains from just an intake that I've ever seen. WOW!

mmm think we can get 60 more whp with mild cams? I'm startin to get worried here...
These cars have the potential to be serious little beasts. With an exhaust, intake, and headers the duratecs will be eating the svt's for breakfast. 200hp N/A should be very doable.
i'm worried about how much low-end we'll have to give up to get there is all.
I don't think we are going to lose too much in the low end, I think the exhaust setup is going to have an interesting effect and I am curious to see what happens once we get headers and exhaust going. I also think that proper tuning is going to make a big difference.
what's really got me interested is what the cam profiles are gonna look like. LIke i said earlier, i'm thinking/hoping that this engine is severely undercammed
I really wanted to leave this thing stock as long as I owned it but it's getting pretty tempting to toss on some bolt-ons with those numbers.
That is how I started too, but I am really enjoying the upgrade. You can't beat the gains and price for this intake.

Edited for spelling and grammar.
126 is exactly 15% loss to the wheels. Which would be the standard for FWD drivetrain loss. This engine is right where it's supposed to be.
good call, Andy. I didn't even bother to calculate drive train loss, i've just been thinking of the 160 hp mazda 3 version and then thinking 22% loss.
