2.4L Full-Race twinscroll 40R - 740 whp / 672tq Evil Built/UMS Tuned/Sparktech ign
this build has what I consider a psycho powerband for a true street car -- 200lbft @ ~3600rpm and 500 lbft @ 5000rpm, then 600lbft @ 5300rpm. 
red line = twinscroll 40R (new setup) compared to blue line = singlescroll 37R (old setup)
the thing to take away here is the big difference in "area under the curve" from his new round of mods (turbokit, head, ignition) The approximate gains with his new setup are
2000rpm +5hp, +20tq
3000rpm +20whp, +40tq
4000rpm +50whp, +65tq
5000rpm +150whp, +150tq
6000rpm +60whp, +60tq
7000rpm +30whp, +5tq

This was a result of A LOT of hard work and bad luck to finally output this setup... It's pretty amazing how much more torque the car makes now and how it hits so much earlier on a bigger setup. You def can't argue that twin scroll works. the dyno graph is an overlay of my old setup (peakboost 37R singlescroll). With the 40R we actually made 750hp but played around with the cam gears to mess with the tq and landed at 740hp. I will try and take some better pics soon. This car is just way too much fun to drive. I went thru 10 gal of q16 in 1 night. The torque is just stupid on the street. I HIGHLY recommend this setup! 
My setup:
Full-Race twin scroll 40r turbo 1.06ar
Evil Engineering built 2.4L 4g64 block
UMS tuned AEM EMS
Carrillo Rods / CP Pistons
Evil Engineering built AMS head 1 mm over Ferrera Valves/springs/Retainers
Tomei 280 Cams/Cam gears/fuel rail
Full blown twin walbro setup -10an inlet -8 return
1600cc injectors
HKS Kansai Intake Manifold & Q45 TB
Garett 24"x12"x3.5" Intercooler core 3" IC piping
Mishimoto evo7 radiator
Tial 50mm BOV
2 Tial 44mm WG (twinscroll)
Sparktech COP + M&W CDI
Aeromotive FPR
JIC Coil Overs
Greddy Ti Exhaust
Carbonetic triple plate clutch
I'm sure I'm forgetting a lot but that's all i can think of atm.
Gotta give props where its due:
Big John and crew @ Evil Engineering
Tony and crew @ UMS Tuning
Geoff and crew @ Full-Race
Craig @ Sparktech - Actually called me to check up on me, thanks again man!
it's extremely fun to drive on the street. Acceleration is just unreal, just crusing on the freeway and hitting it in 5th gear shoots it over 100mph almost instantly.
I'll probably go to the track once it starts to cool down out here. It's too hot to drive around much. Our highs have been 110F+ all week with no end in sight. my girl did come out and take a vid of me adjusting the anti lag. Heres a link to that if you're interested http://www.youtube.com/watch?v=R5K1TjUabsY

That's pretty impressive. 100whp/150tq increase at 5000k and it looks like the full boost is achieved with the ts 40r slight sooner than single scroll 37r. Good Work!

This is absolutely a SICK setup!! Looking for the same performance but with a 2.6L from BC but will settle with 2.4L after these results and I'm not even condsidering going over 700whp. that torque is INSANE. Geoff...I must say, what you and your crew have done with the TS development and the sure performance that it delievers is near god like. Great job.

thanks for the kind words! glad to see we are starting to make a couple believers. my friend saw him at the track on Friday, he was super excited about his new setup. It went something like "I'm a believer now, twinscroll is the ****!"
here is an updated dynoplot from UMS
i recommend keeping it simple -- the 2.4L is PLENTY of displacement to get the job done 
its 150whp/150tq 
and its not just slightly sooner, it hits 150wtq 1000rpm sooner and 200wtq 700rpm sooner this makes a HUGE difference behind the wheel, and even more noticeable at part throttle - which is precisely what you dont see on a WOT dynoplot
just PM antonio010 (the owner of the car) hes a really nice guy

Truly insane numbers!
Is there any way to reduce the degree in which the torque is falling off? I would think that the additional displacement would help with this, and it certainly helped with the huge torque numbers to a given point.
