I seem to have come to a point where my engine isnt making any more reliable power. What I mean by that is that foremost my EGTs is getting to hot if we(me and my tuner) get the power any higher.
Some of you have followed my project and know pretty well what parts I have... My changes to this year is a new exhaust manifold, and stock intake manifold again. Looks like this:
With the same tune as last year, I got exactly the effect I was hoping to get, much better response and not so laggy turbo/spoolup meaning less smoke when changing gear etc. 28mmID pipes and almost as short as possible, not the best collector, but not that bad eather if you ask me Have no better pictures I'm afraid..
After some testing we can now make the car run very good, and also be pretty fast witout any problems, I had spoolup problems last year wich now is gone away with a correct working map sensor. So far so god.
My "problem" is that this car is going to be used on the circuit a few (hopefully many) times, and to have a big engine failure is not an option.
The chassis, tires, breaks is pretty fast on this car and a much stronger engine might fit good.
This makes it possible to take out maximum power almost all the time wich put STRESS on the engine, not even close to the stress that is possible to get on the street(Autobahn not included)
And... I can only have around 220hp(butt dyno) before EGT wants to reach 900deg pretty fast even on the street! 900deg.C seem to me as some kind of maximum EGT to be safe. Right/Wrong?
At this powerlevel my car is almost smoke free accept lowest gears and gear changes, I like that... But if we try a bit more fuel and so, 240-250 hp is no problem, and to make my Helix cluch(now sintered) slip is possible also! But the downside is mainly EGTs and the big black clowd behind the car.
So what do you guys think is the best for me to do? Both me and my tuner think my engine should perform better but something is limiting me. Or am I just to wimpy and should be harder to the engine? Water/meth injection? Better intercooler and piping? change back to D24 intake?
I'm realy glad if you could give me some advices what to do to get this wonderful power I can have, but with great reliability!
Just ask if something is unclear...
