Default Thinking Headers For My Dinan SC

I currently have the Dinan SC (non-aftercooled, but with ITBs, exhaust, etc). It seems like from here, there are 2 routes for more power: The aftercooler kit, which at a whopping $8500 adds the intercooler, fuel pump, oil cooler, extra pound of boost, and updated software - 40hp/10tq. OR, adding headers ($1500 for AP V2 with Euro200r).

On NA cars, headers like these should see gains of 20hp/20tq. With the Euro200r, software is not needed though recommended.

I am wondering what gains are expected on a blown set up? Same? More, less?
Will my software need updating? IIRC, Dinan runs very (too) rich. How will headers effect this?

I don't track my car so I don't think the oil cooler is necessary. I like the idea of not upping the boost, which means the fuel pump is a wash. The intercooler/aftercooler would be nice for cooler air, but won't justify the rest. $$/hp strongly favors the headers, just wondering if gains are comparable on blown cars and if my Dinan software will need to be adjusted.

Thanks!

ideally you would want to do both. but the headers depending on what set up you go with will get you anywhere between 10-20whp. This will depend on the header design, if you go catless or 400cell cats vs 200cell.

headers will not give you 20lb of torque FI or NA. it will be closer to 9lb of crank torque on a NA car and perhaps 12 on a FI.

If I were you,

I would run the 5.5psi pulley probably 2 size down from where you are at with a custom tune. You should also run meth for hot summer days.

Thanks for the reply!
Probably won't up boost anytime soon. Headers will be the next power mod, but not urgent. I just got a CPI RT v3 (section 1) so at some point I will replace it and either go Euro headers/1 or AP V2 headers and Euro200r (more likely). Was just curious if the headers would effect the tune at all since I think Dinan already runs pretty rich. Might do custom tune down the road if/when I up the boost at all, but since it's all calibrated together as it sits now, not worth tinkering and messing with some of that stuff.

Can't go wrong with headers. To give you an idea on power, back in the day when i had the Dinan kit on my car, i put down 360 whp with Jvt/ebay headers...

Sweet. Just ordered a CPI RT3 so I guess I will get some use out of that section 1 before going with headers. I will probably end up with Fabspeed/Euro200r down the road. Glad that no software update is needed; hope they lean it out if anything. Thanks for the #s!
