Electronic Boost Controllers

[MrFlibbles]

Whats all that about then?

I presume they up the boost giving more happy power, but how do they actually work?

I was under the impression that the turbo controlled the boost?

Does an FCD need to be fitted at the same time?

How much would this little lot cost (fitted) and what kind of gains could I expect?

Gaz?

p.s. I've decided I need 300bhp by the end of the summer! (Nothing to do with my mate getting his Z3 turbocharged! )

hmmm...

all this talk has got me thinking about an MRT again...

Damn you all!!!!

Are we going to have the FCD debate again.

I really thing fitting a FCD and winding the boost up is 'chip it and hope' tuning, and asking for #3 piston to detonate......

[Mr E]

And you need to have fuel maps for the boost you intend to run....

[Mr E]

3rd gen 3s-GTE has maps for 17.5psi.

Fuel cut is at 17.5 psi. That's why it exists.

If you're having to bypass it, where is the ECU getting it's fuelling information from?

Turbo's are nt as responsive for adjustability, but the limits are too high for most road use anyway- you'll crash n die if you cock it up, the MX5 is far more forgiving. Also, the n/a is gutless compared to most turbo's, as they dont have the midrange. If all else fails have a go in mine.

Gutless - Yes.

Sod all below 4k rpm, but after that they go quite nicely. You have to keep them on the boil, but that's part of the fun.

They are still fast cars, the NAs, despite the lack of a turbo - Overtaking is dead easy.

Ah, in that case, carry on.

Gazboy,your 'A' spec(iirc) head gasket,is it much thicker than a standard gasket(i.e. 0.2mm or< )? If so,lower compression ratio is achieved & higher(not huge tho) levels of boost are safely possible(so long as the I/C can cool enough air).Lowered compr can also help to negate increased boost/detonation probs & therefore save melting holes in your pistons

[Mr E]

Mmmm. But the one thing the Deuce isn't good at is cooling. Engine is in a silly place.....



WI could well help, but I wouldn't push a 3S-GTE much past 300bhp on stock internals...
