Forced Performance Buschur Racing HTA86 .82 turbo review 700awhp DLL @40psi stock ecu

I've had the pleasure of running the HTA35R with the .63 for some time and saw some nice 600awhp DLL's on the stock mas/ecu and 93 octane which propelled the full weight Mellon Tuning evo to 10.41 @ 135 as some of you may already know.

I've been very pleased with that setup. Then came along the HTA86 which promises similar spool and more power and an opportunity to go from the .63 to the .82 which I suspect becomes necessary as you get into the 40psi range. My carefully calibrated butt dyno sensed very little change in daily driving an WOT power. I ran some logs through DLL to see the difference and it agrees. I also noticed that to achieve 33.5ish psi on the HTA35R .63 I had my EBC set to 72% duty cycle and now with the HTA86 .82 it's only 66% duty cycle. I was seeing 10psi by 3500 on the HTA35R and now I'm seeing 7-8psi by 3500 on the HTA86. I plotted the boost curve in excel taken from measurements I saw in my video of the boost gauge vs RPM. Sorry I don't have an overlay with the HTA35R.63

here's the DLL from on of the 3rd gear pulls at 32psi on 93 octane




I later did a g-tech run to see where I'm at and with the tires blazing through first gear and lifting to shift:
60' 1.88
1/4 10.80
mph 136.9

I'm sure this could be improved with better traction and powershifting..also I only made on attempt

I went out on q16 and eased the boost up to 40psi...some pretty nice gains after 8 or so tuning pulls.

the first chart is the new one and the second is c16 @ 40psi vs 93 @ 33psi. Keep in mind I went 10.41 @ 135 when I had 600awhp in DLL with a 1.68 60' on the 17" BFG drag radials






here's a video on pump and race gas

Big thanks to Buschur/FP putting together a killer combination...I feel pretty confident about going 9's in 09 with the stock ecu/mas
