Any reason to go larger than 435's on a 12mm pump?

update -
Went back to the stock pin turned to the deepest setting.
Cut way back on smoke - no kidding !!
Still able to 44psi and can blow smoke on demand.

I think I'll stay here and drive this way for a while.


BTW - I watched my egt's carefully this time out and easily hit 1300 and went to 1500 in about 35 - 40 sec. so I'm pretty sure I've still got lots more fuel than I can burn comfortably. Smoke did thin out once boost hit 44.

My egts get 1500 plus too but much quicker due to it being a 60mm H1C.

Richie do you think my truck would be quicker with the fuel turned down and put a 60mm compressor on the H1C, i already did the 16cm exaust upgraid?

Quicker, I don't think so. Basically all the 60 mm upgrade does is give you a little more air at a cooler temp. I have read that some people put a egt gauge in there turbo outlet ( to measure temp of compressed air ) and have had numbers 450 plus degrees ( on stock turbos at way over recomended presure). So as far as I know, if you kept your fuel settings the same you might gain a little power but the key is how long you can use the power. The upgrade should let you stay on it a little longer due to the turbo being more efficient at producing air at a lower temp and a increased cfm. The 60mm upgrade is a band aid upgrade. Most likely it will not cure your egt problem, just give a couple more seconds of power. My egt is well over 1500. It will pin the gauge in 4th gear with 4.10's.

I have a Stage IV compressor with a 16cm housing, and I think my POD's are limiting me. Thinking about 6x.016's but they might privide way too much fuel at my altitude.

No such thing as too much fuel until you start to quench the fire...

Actually you probably could turn your power screw out thus limiting WOT fuel.
That's going to be my next trial. I'm still getting more WOT smoke than I'd like - at 70 I can go WOT and black out both lanes.
One is really enough

I already got turned in to the polution Nazi's and had to submit to a snap test. I don't want to do that again (at least by accident!)

If your worried about smoke don't get 6x16's.
