Ok i came here in hope that guys that have decent knowledge can help me.
I drive a BMW and most of the guys there havent even taken apart an engine, much less know how one works. Im a big fan of anything Dodge related, or muscle cars for that matter. Im not bashing young guys like myself (im 21) but most people on the boards i go to are morons and have the ricer mentality.
So here is my question.
Generally speaking, im working with a 2.7 liter SOHC engine. It produces 174 foot pounds of torque, and about 132 HP stock.
Compression ratio: 8.5:1
Bore/stroke: 84x81 mm
Now this engine was meant for economy, it uses a bigger stroke than its 2.5 liter counterpart, they share the same inline 6 cylinder motor.
Now ok i get this bigger stroke increases displacement obviously...but im trying to work with direct bolt ons.
The stock compression is 8.5:1.
My goal is to make it a low RPM powerplant, and put a bigger gear ratio like a 2.93 or 3.25 instead of a 4.10 to make up for the loss of revs, because the engine will be a low revving high torque engine. Thats my goal at least.
Ok basically, im asking these things:
How much more torque do you think you can achieve with 10.5:1 compression, a bigger cam like 292 duration, the stock is like 260 or something weak..dynamically balancing EVERYTHING, basically blueprinting, performance bearings to withstand the heat and friction, decking the head as much as it will safely allow, you can deck it .020 until its too much.
People say this wont get you from 173 to around 200....they are joking right?
I dont get it, either they dont know what they are talking about or is something wrong?
I know that even doing a cam and rockers on a muscle car is at LEAST 30 torque at the very extreme. Like a 454 or whatnot. Is asking for 240 torque too much?
I dont understand how it cant produce that much power.
I mean if a 502 cubic inch can produce at least 502 torque, why not a BMW with newer technology? 1988 car by the way.
I know this doesnt belong here but i want peoples opinions that have decent experience racing, building engines, that are at least my parents age or understand cars at least!
thanks for your help/opinions.
My first car would have been a challenger if the previous owner didnt wreck it 3 days before i was supposed to buy it
