Jet size for 2010 Audi s4 3.0t engine direct port?

infinkc · #1 12-07-2013, 06:39 PM

I can't seem to find any info on what the stock injectors put out on this engine. Anyone have any idea what size jets to run for a direct port application (6 jets)?

I have an hfs6 that i will be using.

Hate to buy 6 valved jets @ ~$55ea and be the wrong ones.

Will be pusing about 13-15psi.

50/50 meth

Thanks!

After finding out more info on the tfsi engine, is it even possible to use an aquamist system since there really isn't a set idc?

Yes, we have setup many kits for the TFSI. Roughly you can say 1.5 x the HP for jetting, or for a 300hp engine, 450cc.

Jeff,
Will the hfs6 work for the DI engine? Or do I need a hfs4 for this car?

The HFS-6 is not setup to work with this injector setup. In the past it was modified to work, but the new systems do it much better. The 6 was discontinued a few years ago and other than spare parts supplies, is not supported in that manner.
