How does stage1+ compare to stage 2? Which is more powerful?

But you do need the upgraded intercooler.

Is there a big difference between the two? cause now i want to sell my downpipes....which i JUST ordered!

Stage 2+fmic will be well worth what the downpipes cost. in my opinion.

Definitely glad to see that the stage 1+ MAPS are now available!!!

Don't sell the DPs. Stage 2+ is more powerful and definitely worth it. Plus going forward I guess maps with even more power will require DPs!

Spending $400-800 for ~10-15 whp is not very cost effective IMHO.

Well I think that ROB may have had the DPs on when he tested stage1+, may be he can clarify. So the 10-15whp he got when he flashed s2+ was due to the tune. DPs alone should yield 10 to 15whp.

My car is a whole new beast with stage 1+ I think I saw 17+ psi while data logging yesterday! Amazing upgrade Cobb!

when going WOT you saw 17+?

Rob@Cobb · 03-09-2012, 04:34 PM

There is power to be had in DP without cats when really starting to push the turbos on the race maps. Removing the cats helps with the excessive pressure between the head and turbos.

Rob

max · 03-09-2012, 05:03 PM

Understand what you are saying about pressure upstream of the turbo, However when comparing Stage 1+ to Stage 2+ the addition of DP nets only 10-15 whp from what you stated.
Us mere mortals do not have access to race maps.

Peace.

I would be very interested to see dynos of stage 1+ vs stage 2+. I was thinking the same thing, if stage 2+ only nets me 10-15 extra whp why mess with DP's at all? Now maybe the TQ area under curve is far superior w/ stg 2+, or other factors, but in terms of peak HP that is not enough reason to get DP's @ $600 or so.

enrita · 03-09-2012, 05:32 PM

just amazing... backpressure is bad when pushing boost to redline. you guys focus on peak power, there is so much more power to be had across the power band with stage 2plus all the way through redline....
the whole power band will benefit with downpipes and more boost/timings....

It's not uncommon to see that in mid-range. The turbo's are in the efficiency range. 17 PSI at redline,different story.

Correct, 10-15 HP on paper might sound boring, but when you stamp that across a large area in the powerband the results are quite fulfilling. The reduced back pressure also results in less knock tendency and lower EGT, all great for the recipe of a healthy engine and happy one to boot.

I should have some good fresh Stage 1+ to Stage 2+ dyno plots soon. A friend and customer will be stopping in next week.

That would be great, thanks.

Will be real interesting to see the delta of exactly how much whp downpipes add to this equation. Everything else is just speculation, show me some numbers folks.
Trying to justify spending the $400-800 on my next mod. Would like to see gaining 40-50 whp for the money spent. If it's only 10-15 whp then it's not worth it IMHO.

Mine looks very similar to lawwailok except I'm running the aggressive map.

i agree... very very similar... so by Aggressive map, we are looking at an extra 1-1.5psi more over Sport according to your data. good to know.. im planning to pump some 100 octane and run the Aggressive map for a few days =)

EastCoast335i · 03-12-2012, 11:54 AM

Installed Stg1 +FMIC and its a night and day difference from Stg1.
More power throughout the entire powerband. I'm loving it!

Cant wait til my DP's get delivered to bump up to Stg2 +FMIC...
I know an intake is recommended with Stg2 +FMIC but can I get away with just a drop in BMC filter?
