blue printing..

I've read a fair amount of reports that blue printing the bottom end of your engine is a good way to increase power and strength.

Two questions then spring to mind:

What exactly is done when you blue print the engine?

How much would this cost?

Thanks

the way I understand it is that....

Blue printing is basically a map of your engine and tolerances in the existing internals, this allows you to take your blue print to any specialist who can machine forged internals for you to your exact tolerances and thus make you engine stronger and you can have confidence when turning the power up...

be prepared to pay around £1-2k for blu printing plus all your internal bits, fitting and alot of time..

worth doing if you have the money and want to get some serious power out of your car...

The way I've always understood it is a bit different. When the engine is designed all parts are given optimum sizes for best performance. However, when you get down to producing thousands of them there has to be some allowance as it would be far too costly (and unrealistic) to have everything to this exact standard so a tolerance is applied. The further you drift away from this "optimum" then the less your engine resembles what the designers originally came up with. Blue printing involves taking your engine, and machining everything back to the original design (or Blue Print).

I think realistically it's a lot of outlay for minimal gain - but it depends on what you want from your engine, what you've already done and what else you're planning to do.

Thats what I thought...... but I could not put it into words.
