Re: To tweak the fuel pump and add intercooler or not??? Advice needed....

...which means if

the same fuel is burnt, the exhaust temperature is lower by a lot more than >the reduction in inlet temperature.

So I'm guessing that its almost an exponential relationship between air in and EGT when all other variables are kept constant.

This then explains why bigger / more efficient intercoolers are required to stop your head / valves burning away.

That poses another question...

If tweaking the fuel pump and boost combined with new intercooler will allow for more power whilst still keeping the EGT within tolerable levels, how do you know if youv'e over-egged it and taken the EGT outside of those tolerable levels, thus affecting the longevity of the engine???

Do the people like Twisted Performance, Allisport, Allard etc check EGT, Boost etc etc and setup correctly or simply assume that an engine is setup up in a standard way and adjust all vehicles the same? This must be the way they get DIY'ers to install them as most dont have spare boost or EGT gauges...do they?

In a nutshell, is a DIY option a realistic / reliable one. Can I really adjust my engine like one of the specialist companies can?
