You cannot build pressure by turning the engine over with the starter on a modular engine. It's a Gerotor oil pump. Doesn't turn fast enough, ford even says this in the engine docs. It's not like the old style engines and oil pumps. You can pre-lube it with a pump
They don't make any low end power and the gearing of the manual is too long. Sure, all you have to do is downshift but the Whipple changes the powerband way more.
A10 with the centri is fine. You'll still be a lot lower in rpm with every shift in the manual.
Neither of them make boost at low throttle inputs
I personally wouldn't want a centri with a manual, but you should try to drive both setups before you buy.
3" is a waste IMO if you're going to just put a 2.5" on the end of it, but again there's only one way to see the actual numbers. and guys are making big power through the factory 2.5" mufflers
Getting rid of that 2-1/4" section has to be a good size gain but again...
Where are the Engine...
I just want to see what the difference is on the dyno is. Is it 10? 20? 50? As i said people are flying with the stock active exhaust so it can't be that big of a restriction.
I'd be interested in seeing the power difference on a dyno of the stock pipes with the active exhaust vs 3" before the active exhaust...
Guys are out there making over 900rwhp and running 9.0's with a full 2.5" exhaust (including factory mufflers) after the headers
Can you buy from Amazon, Partsgeek, etc?
Most stuff from Rock Auto is half of what the parts stores charge. And some things like brake rotors might be 25% of the retail price!
It would suck to lose the ability to buy cheap parts like that.
90% of the people out there just want loud. That's why there's so much shit like muffler deletes out there.
I put a pair of these Jegs bullet mufflers on my car, basically smaller resonators. Other brands are bigger and have more packing but for the price and size I figured what the hell.
They...
Walmart has the deals on oil. Hard to beat Supertech full synth for $18, Castrol Edge for $23, Mobil 1 (on sale) for $25, Pennzoil Platinum for $24, and Royal Purple for $33 if that's your choice...Plus they have Motorcraft filters
