A bit of tuning & maintenance

[911Jarle]

Hello guys!

Still having fun forth and back from work

I am however doing some maintenance to the car. One thing I notice, is that some times during engine braking or very light driving it shudders a bit. I've read some things about decel valve, could that be causing it? I am going to change, wires, plugs, oil & do a valve adjustment from the back anyway.

Then to a bit of tuning questions.. I think the sound is a little bit tame. I have a US 3.0 SC engine, with original exhaust in place. I am not intending to drop the CIS or anything, since I will drive the car all year, even wintertime. I'm just looking for a bit more sound and perhaps a few hp more...

Thinking exhaust, filter and maybe some timing changes... Good tips for nice parts to buy and stuff to do with a standard SC engine with CIS in place. What sort of power can one fetch this way?

Anyone swapped in a more modern EFI system on an SC engine? Like Motronic for instance? A lot of sensors has to be mounted and stuff? I have a bit of experience with EFI, since I mounted Haltech e11v2 in my garage on my Maserati single handedly.

Thanks!

In my opinion, most SC's need to be largely disassembled, then reassembled using some fresh parts. Engine mounts, suspension bushings, etc. This makes the car feel more solid.

I like my Triad exhaust.

Modern EFI systems are very popular.

My engine was out not long ago, a good workshop put it in again.
I have to assume they did what they where supposed to do then..
Anyone else have some tips on the issue I describe?

Thanks a million for the exhaust tip. Looks fab. Do you have SSI headers etc as well?

Cheers, Jarle

i just put a dansk pre-muffler on my SC in place of the cat and love it. it got a little deeper at idle and maybe up to 2k but after that it sounds like normal. i doubt it did much in the way of adding hp but the car has enough to thrill me already.
