WASTING UR TIME Phil clearly they LOVE der NARROW POWER BANDS ON STOCK INTERNALS clearly!!
different FOLKS for different strokes
but clearly if we were to get all technical and maybe start breaking things down a bit like say the Pistons material composition and then get the specs on this and then work out its Limits,(stress limits , Heat ,friction) also the rings and then we could go and break down the HEADGASKET composition!! which clearly will not run 1.5bar boost end of story.
whos up for the Challenge???
Or will we just all go with the theory if u DONT BELIEVE ITS BECAUSE U HAVENT DONE IT???????????????????????even tho im building E-series engines for the last 8 years(forged and stock) to all specs required and working with them the last 10 years???????????
Hard FACTS dont lie.
U THROW HIGH BOOST ( 1.5 Bar) at a stock engine 4E that is its gonna let GO!!
Good lord man, all I'm doing is sharing some details of a car and trying to provoke some discussion a bit more interesting than which fpr you need to run 1bar on a ct9. As you say.. hard FACTS don't lie. Here's some more.
Yes, it's had headwork and raised the rev limit AFTER that graph. At the time of that 350bhp graph it was an UNOPENED MOTOR. e.g 140,000+ km stock standard untouched, standard head gasket, standard manifolds. Yes, in standard form this does give a very apparent narrow power band on the dyno sheet, however in practice it was quite usable. Unfortunately it never ran the 1/4 mile in this state, but it certainly would have done better than 14's with an experienced driver at the wheel.
It ran on the tune and spec from that graph for months, daily driven, running 1.5bar on pump fuel. I couldn't give you an exact timeline but I believe it would have been at least 6 months. Prior to that it was running a TD04L turbo and almost as much boost! All in all the car had a couple years of your mystical HIGH BOOST without so much as a single niggle with reliability up until it cracked a ring land due to fuel.
The car I posted a video of was running 1.5 bar on a stock headgasket and had been for many months, various other turbo setups in various states of tune for many months before that. It continued on reliably for another 18 months after that video before being sold.
Sponsor me the costs, I will do a heavily documented factory spec rebuild of a standard 4e-fte and then lay down 350bhp. Hell I'll even use second hand pistons if it makes you feel any better.
If you've been building E series motors for 8+ years and can say with conviction that the stock headgasket won't take more than 1bar, then I must conclude you don't know what the hell you're talking about.. it's been proven time and time again, here and in plenty of other places (that all run faster times than england) that it's not only possible, it's consistently possible and reliable.
