I'm not trashing 3 cylinder turbo fiestas. But tbere are limits. How much hp and tq gain do you guys think could be had for $1,200 bucks in bolt ons? My original reference was regarding potential gains from bolt ons. Not stock output. I Prob should have been clearer.
Well see here is the deal. First off Ford UK who builds Fiesta ST engines and Fiesta engines is not new to the 3 cylinder deal. They have had time to figure things out. The 1 liters are very relaible engines even if they are small.
Second off you guys get hung up on the idea that if its a 3 cylinder is must be weaker throwing out all logical analyis of the concept. The engine is only 100cc's smaller than our current engines. Therefore output and theorotical output should not be adversely effected provided you use properly strong components.
They key to power with turbo charging is proper air fuel ratio combined with good flow amd components to handle the increased pressure of forced induction. Most factory forced induction engines are purposely boosted below their full capabilities by the factory for the sake of longevity.
Now we saw that back in the day with Nissan's famed SR20DET, their RB25DET, CA18DET, RB26DET, all of which were quite capable of much higher horsepower . Our current FiST engines are the same as well as the other Ford Ecoboost engines.
So why would it be different all of sudden when Ford UK is known for building stout little Turbo engines?
It's your disbelief about a 3 cylinder that automatically makes you think it could not be possible. If you stick a larger Turbo than stock on that 1.5 it stands to reason you will get more HP and if they could extract what they have in a production engine than it stands to reason its got room for more. As the factory always goes conservative in the name of reliability.
When People ar getting 500hp out of Mustang Ecoboost 2.3's. People are getting 300+ HP on stock internal FiST 1.6's, there is no reason why the 1.5 would not also be strong enough to handle a bigger turbo ( around $1200 a little more or less) .
To build the engine at the peak of its capabilities like some of you are trying to claim for daily driving cars is ludicrous.
Everyone knows the minute you build an engine to the peak of its capabilities that reliability goes down drastically. Race engines are not torn apart and rebuilt often just for giggles. Its because they are at the peak of their capabilities and when that is done longevitity i.e. Reliability suffers.
Hmm automobile manufacturer going to sell a engine at the peak of its output capabilities and offer warranty. Knowing that it will not last long? Lol
