Engine Stage 3
Too many people still to this day only look at peak figures….. believe me, this means nothing in the real world and the quicker people realise this the better. Personally I would rather have a better power band and the utmost reliability for the sake of a couple of BHP less.
People also carry on about Rolling Road tuning compared to Road Mapping. As an end user I don’t care about the intricacies of the benefits of one over the other. The Spec C has always been mapped on a rolling road (with tweaks made based on road driving feedback), but ultimately the car delivered and stayed in one piece….. this is what is important to me as a customer, so is all I need to know. What ever it takes to get the job done me thinks!
Initially we made the concious decision to look at what could be done, that was effective (i.e. actually works) and within a reasonable budget. What was achieved during Stage 1 and 2 met those requirements quite nicely.
Car modifications you can always take that one step too far and ruin an already brilliant car. With this in mind the original thoughts were along the lines of "Stage 2 - Thats it!".... unfortunately we were kidding ourselves to think that further development would not take place!
We were already thinking about what could be done with Stage 3 prior to finishng Stage 2, and we alluded to what some of these options could be.
Those areas of interest were:
1) Big BHP – Totally new engine (either 2.33 or 2.5ltr) normal position turbo
2) Big BHP – Totally new engine (either 2.33 or 2.5ltr) rotated position turbo
3) Keep with the staged approach, trying other various modifications in specific areas
Where do we start!!!!
Let's make this simple.......
a) 2.5ltr was the weapon of choice since PowerStation / Litchfield Imports had already ploughed endless hours of development with Cosworth in to a reliable and powerful engine. This made the interest value of the 2.5 more, especially since the UK market would only be getting 2.5 engines in current and future STi's.
