To be fair though. At least here in Aus I do know of tuners who blow up car after car after car. Hell with one guy they blew his stock engine and 2 built ones. At a measily 220kw. Due to bad tuning. There's only one tuner on earth I'd let tune my car and to be honest, I don't know if he's had one pop yet. Period.

No doubt a good tune is a necessary component to engine longevity.

No argument from me, the factory rods are shit for FI. At the same time were doubling the rwhp and crank hp.

SUB-FT86 · 12-14-2015, 09:00 AM

I couldn't care less about 300+hp on a 2800 lb RWD coupe. The fastest street car I've driven was a automatic 335i which makes 265whp/300wtq in a 3550 lb behemoth of a body and I was blown away by the straight line acceleration. I would be happy at 235-250 whp-200-210wtq so a low psi turbo sounds like a plan in the future.

Oh man good read so far I have learned nothing yet

RichardsFRS · 12-14-2015, 09:39 AM

Agree with Sub. 300whp would be crazy. I would love 200 at the wheels after loss. Can you do that without turbo or blower? Can you buy a small displacement blower or turbo that won't wreck the engines? 300 would be fun but a lil dangerous for the engine

Everyone loves how I like to harp on about Cosworth. I'd put lots money on them having done the most extensive R&D of any of the FI kits avaliable for the FA20. So here we go, they have tested the rods. Snapped rods. Done materials analysis on the rods. Done engine simulations using some cleaver software. Done enduracne testing on an in house engine dyno. Done a number of trackdays all over europe in sub zero to 35C temperatures.

Their engineers determined 250WHP was the absolute max they could stretch from the stock block and maintain 100k mile levels of reliability.

I know of a centrifugal charged car (not naming anyone or any kit) recently blew a rod at about 300WHP. The other 3 rods were showing signs of high cycle fatique too...

I feel for guys like Delicious as they always get blamed. Just because one car survives 350WHP for 3 years while being thrashed, doesnt mean that is a safe power level for every engine.

RichardsFRS · 12-14-2015, 09:41 AM

All that being said I still think my car is outrageous fun in its stock form for a DD

Exactly why I have the Cosworth 2.3 kit! Pretty long history of building racing engines for Porsche and many, many others...

Not to mention Formula one engines!

GD everyone saying "300 HP would be crazy" or "250 is enough" is getting old on this board.

Some people think the 170WHP is enough.

Horses for courses.

Sure, but it is like every time any one says "I want more power" there are a million people saying that stock is enough. Or when someone wants to push more power with a turbo kit or something.... it just gets old.
