Which means the intercooler is doing its job. The same volume at cooler temp is going to have less pressure. I read on a site sometime ago, that porting heads was not recommended on a turbo'd engine since it causes a loss of boost. Simple terms is boost is what is not making into the cylinder.
I would love to read that article because their theory to me sounds wrong. Feel free to pm me a link to it.
You're correct. While you can't say decreasing boost will increase power, you could actually decrease boost pressure by porting heads, increasing flow and creating more power. Any time you can increase the air + fuel mixture you increase power. So you have to look at it all together, not just a boost number.
I did that very thing with my '93 Super Coupe. I ported the heads, ported the living crap out of the exhaust manifolds, and even after adding a 5% jackshaft pulley I was still down almost 2 lbs of boost over stock. But, even though I never dynoed the car or ran it on the track, the seat of pants acceleration was improved a lot. Even though boost was lower, airflow was increased allowing it to make more power.
OK well I have an email from the stating just the opposite. The email is definitely all the legal proof I need but wouldn't help anyone else. That's why I said it would be best to reach out to them on your own and in writing. The fact that I have something in writing from them is binding. If it was just a phone call, I couldn't just say well they said so...
Thanks for the update... good info.
This is FP covering their butts. As stated above, the car utilizes speed density instead of a MAF setup. Using another high-flowing intake shouldn't present any problems.
Ford sells colder plugs on their website. They're Denso ITV24 plugs (two ranges colder). I'm not completely sure why they recommend two ranges colder, as one range colder seems to be about right for a mildly modded stock turbo car, but nevertheless, that's what they sell for use with tuned 2.0EB and 2.3EB cars.
