Supercharging an E16SE

[RobMarriott]

If it's been answered before, then I apologise, but I couldn't see an in depth reply.

Basically, I need to know what to do compression wise, does anyone sell low compression pistons, or would I have to use a spacer plate?

Also, using an Eaton M45, does the throttle body need to go between the charger and the engine, or between the charger and the air filter?

Cheers.

yes people sell low compression pistons dunno where tho not looked in to it but ive seem them about on the net, throttle body usually goes between charger and filter but i have seem them between charger n engine but usually in multi throttle configuration cant see it being good for the butterflies unless it has some for of bump valve or bypass which i dnt think the m45 has ?

mahle will do the pistons, dunno any suppliers tho

Hmmm, I think Mahle's head office is on an industrial estate near me, I know KKK have an office up there, but I'm sure Mahle are too.

I might give them a call.

If anyone else knows where else can do them though, that'd be great.

mvaux do them

Ok, next question.

Will the standard management system cope with a small amount of boost with larger injectors, or am I dreaming?

How do the turbo people normally do it?

theres a guy on here who had a c16se i think, he had some sort of swith??? with standard management. have you seen the replies in the 8v block 16v head thread?

The standard management is set for standard fuel pressure, so large injectors will just flood the engine over the entire rev range.

You need some way of upping fuel when on boost (i.e. aftermarket management which is mapped for positive pressure(boost))

You can "bodge" it with a dual rate fpr, or a switch to "trick" the ecu into just dumping fuel in randomly.

[RobMarriott]

I see.

Well, it's a budget build, and I guess the FPR way is cheaper than a chip/remap?

Where can I find a dual pressure FPR? Can't see any on ebay.

Probably best emailing someone like courtney etc and seeing if they sell them seperately.
