Hey everyone, my first post here hope is helpful to some. Here is a great comparison from stock making 328whp to the 348whp with ETS Catless Downpipe and Exhaust system no tuning, then did MHD OTS Stage 2 93 pump map putting down 425WHP. Stock the car felt great and it ran a 12.3 at 114mp. with just the upgrades of the Catless Downpipe and exhaust system it sound amazing but I felt the performance was not what I was hoping for lol but I was happy. After the MHD map and my first street ride I was the happiest Supra owner in the world the difference was night and day! Now moving on to more upgrades, pure turbo, meth kit, intake, forge boost pipe and having Mickey (Michael Botti) Tune the car with ECUTEK next week. I will post the dyno numbers to have all four comparison.

MHD with parts no E85 just 93 pump. I dynod the car with just the parts first before doing the MHD so I can compare.

Yeh. I got the 93 part. You mention you're planning meth injection so I was just wondering if e85 is an option where you live.

So what is the consensus here on what might be the max HP this stock engine can handle?

we are up around 800whp right now, just gotta throgh back on the dyno for the 800whp verification. keeping torque around 700ft/lbs As above that around 760tq or so, the trans clutches (with stock TCM tune) cant hold anymore.

EDIT:

will i tell customers to run as much power as we are? probably not without them understanding what can happen. for the general masses, i would tell them to leave torque around 625-650ft/lb and power around 650whp for some kind of longevity

How much power can I expect to gain when I switch from your 91 octane tune that I am presently running to your E85 tune that I am awaiting? Stock downpipe.

Any idea how much the full exhaust increases #s vs downpipe only?
