Risk Of High Psi

[byi]

I am currently in the process of sourcing a Ford Flash box but am unsure to the possible damage / stress that may occur to my vehicle with a higher level of boost. If running 10psi what are some areas that may become problematic and expensive with repairs later down the track?

I am aware that installing a set of performance valve springs and retainers can help reduce the risk of stress, are there any other percussions I should be aware of?

Cheers

Does a rod through the block sound expensive......? Cross my fingers hey

There are plenty of people on this forum who run standard motors and a lot more mods than a flash tuner and only problem they have seen is valve springs, I dont think you will have anything to worry about with the stock motor running a flash tune

Whats the price to change valve springs Fat man......$500?????Fitted

Are you going to create a ticking time bomb, that is the question.

My opinion for what it's worth, which is'nt much is it will all come down to how you drive it. Flog it and somthing will give sooner or later, even on standard boost. I've been running 10psi for about 3 months and I know one thing, you will tend to drive alot harder when you have the extra grunt. No problems for me so far.

Unless you are constantly going nuts with it, you should never see an issue due to a 10PSI boost level.

Well the potential is always there, however, provided you have a sensible tuner do the tuning for you, you should not have any trouble.

I have not head of anyone having engine trouble with 10psi generic tune from CAPA, so you should be OK.

Valve springs have nothing to do with the stress of the engine, but will only make it run rough at max boost if these are too weak, but again you will probably be OK at 10 psi.

there was aguy who put a rod thrugh the block even before the edit was available. he was a member on the other fordforums site... his car was stock... There was another member on the site who had bent rods on a stock motor running stock maps....

so go figure

the possibility of failure is always there... regardless of what you run.. Driving style comes into play as well... obviously the more you pump through it the more the risk increases

There are always risks, and it is a case of looking at and balancing these - you know how your drive - so this should be an answer...

Expect some higher maintenance as other stock parts wear out more quickly, but in general - most XR6T's have proven reasonably durable at boost levels above stock...

Cheers,

The 4 speed auto is a weak link at higher power levels, though I believe not as bad as the T5 manual box. As mentioned already it depends on how you drive.
