Just a couple of questions: -

1) Mandrel bent intake - who would be able to make these for me in perth?

2) Fuel pressure regulator - my car runs pretty rich especially at idle (Cam+Chip) - could I buy an adjustable fuel pressure reg to pull some fuel out of the mix? Opinions/Advice appreciated.

3) Leads - I have a pretty big cam with chip and all the rest, would getting thicker leads make a difference to spark etc also what about spark plugs. Is there anything else you can do to get a better burn?

4) Head shave - How much can I take off my AU head safely i've been told you can take 0.20thou off easily enough which will up the compression quite a lot.

Hope some of you's can help, just need to know before I spend the money

thanks guys

1) dunno i am not in perth
2) yes, it will enable you a more acurate fue/air ratio and tune
3) bigger leads = better spark, i got 9mm on mine even bofore i put my crow S3 in, dunno about diff, but never had it misfire, definately wont be a step back
4) i took 40 thou off mine

where would I get the pressure regulator from? how much? what type should I get?

cheers

For the mandrel bent intake, speak to JMM or di filippo. Because they both post, and their pipes are fairly identical, and similar prices. ~$370 + shipping.

Waste of money really look good but my vinidex drain pipe works the same and made no difference.

2) Fuel pressure regulator - my car runs pretty rich especially at idle (Cam+Chip) - could I buy an adjustable fuel pressure reg to pull some fuel out of the mix? Opinions/Advice appreciated. This is a good thought. You need to get it adjusted on a dyno ( usually lower pressure works better) Go to Auto One about $90 with guage I think. The Malapasi stuff is good but exxy!

3) Leads - I have a pretty big cam with chip and all the rest, would getting thicker leads make a difference to spark etc also what about spark plugs. Is there anything else you can do to get a better burn?
Good new stock leads are fine. Maybe a set of (JMM Dev spark plugs) Autolite 985's for fun. I didn't think they really worked but was surprised they worked at all as they were very different.

4) Head shave - How much can I take off my AU head safely i've been told you can take 0.20thou off easily enough which will up the compression quite a lot.
Compression on the AU head is high enough unless you've ported it and removed a lot. Compression isn't that bad on the AU I6. waste of money again.

Ithink the Di-Fillipo racing one is stainless-----JMM one is mild steel or coated.

jonbays:
i have to disagree in point 4 with you - 9.6:1 is a great starting point, but i have found further increase of compression ratio is very easily handled, even by the ECU and for 50 bucks decking i'd say it comes pretty close to bang for buck .. especially when u replace the HG anyway

ftr_el · 11-08-2004, 21:34

any probs with idle and things like that when you deck the head

EvilChief · 11-08-2004, 21:42

no probs ... ecu has a little hard time with my cam thou .. tends to idle at 1100 these days
