DA = 900 - 1100 ft

2010 Touring 7AT
Mods are:
Empty trunk - 3450 lbs with 250 lb driver
Enkei 18 x 10.5 rear wheels w/ MT ET Str SS 285 tires @ 23 psi
MT skinny fronts on 18 factory spare wheels
Stillen G3 Intake
48 row cooler (ET penalty due to weight)
Mobile 1 10-30w oil
DIY ported upper and lower intake
Motordyne ART pipes
Ackrapovic CBE
No yaw or traction control
10 gal E85
GTR Injectors
Ecutec tune
3.69 Gear w/VLSD
Odessey 680 battery
Synolimit TBs
Z1 2 pc front rotors

Car runs good, but it is maxed out and is going about as fast as it can with the power available. Happy with the 12.89 but feel like the Ackrapovic exhaust may be holding it back? Scratching my head on what to do next...any suggestions are welcome.

Hmm IDK man we have very similar mods so you should be close to what I run. Only thing I can think of is you need better weather. I was running 12.6@111 in 900 DA this summer. I ran 12.45@113 yesterday in -700 DA. We are both on E85 and I think the biggest differences are that I'm on UPREV, have long tube headers and im on stock gears. Are you dyno tuned or street tuned?

Actually track tuned on about 12 full 1/4 mile runs.

Each one data logged, and tweaked.

I also have Ecutek racerom timing control on the cruise control button. So, i can advance or retard the timing +2.5 degrees or - 2.5 degrees from nominal WOT TIMING. So, I had advanced the timing until the MPH fell off. Then I backed up slightly from there and got the best ET 12.898 and MPH 108.38. So ignition timing is pretty well optimised.

Skip e85 & go for e90 :eek:

I've got some injectors already collecting dust, would just need the pump and tune, I just hate the pain in the arse trying to find consistent e85. We are supposed to have some good weather this weekend for IFO... And will have several vq out there for a showdown for the fastest N/A in Louisiana. If I can't break a 12.24 I will go ahead and do it, seeing all the pressure y'all are putting down

I didnt even install a pump.

Just some $120 GTR injectors from fleabay.

I didnt want to install admin intakes and 3” exhaust either.

Heck as well as you guys are going with Uprev, that may be next!

I doubt your exhaust is holding you back. I went from a dual 3" exhaust to a single 3" and think 2.5" duals would probably be fine

Be sure you have plenty of fuel available (injector sizing & pump size) as it will require nearly 2.5x as much fuel as an N/A engine at that boost level :ugh2:
