To be perfectly honest no one has ever mentioned that Lucas stuff to me as any good. The 3 that have always been recommended are Torco, octanium and boostane. I think you think it’s working but you’re just not seeing any knock because the 93 in your area is decent.
But it's low compression, higher boost. It's in the bag
Just curious, what is your current combo? Not trying to discredit your efforts, experience or be condescending in any way. Just want to know what you roll with.
Currently I am running a 2018 mustang GT A10 with a stage 2 Whipple. I’ve swapped to the stage 1 pulley (and considered larger) to ensure reliability because the supplied pulley doesn’t leave much room for error.
piggy backing on that ive seen a few logs from guys running at or close to 1.00 lambda at 130+ on pump e85 close to 850whp and not blow. Man did it like 3 times in 2 weeks, first pullied down on DW400 and BAP and went lean up top. Then installed a fuel system, put down 880whp and did 2 back to back 40-140 pulls on a single Ti-274 pump, the secondary 285 pump's power supply wire fell off the FC3 controller, went to almost 1.00 lambda both times and its still running. Stock Gen 3, 12:1 comp, 15psi.
more cubic inches, turbo less parasitic loss, @146 weight dependent prob made 900ish crank horse. OP wants 900 RWHP, with a centri blower, with 30% less displacement.
We're unclear. You tell us. Is your position that someone should run 8.8:1 and E85 with a zillion psi on a pulley the size of a bottle cap?
I have been completely clear. I tend to think you folks are either using the straw man tactic or you’re arguing with what you think i think. I haven’t stated or implied anywhere that low compression is ideal for E85 or that pump gas is a superior fuel for racing.
Correct on cid and turbo losses. But as compared to the turbo LT1, our cylinder heads and engine controls are vastly superior, we have 25% more rpm available, and the 18+ has DI. The old LT1 didn’t make power past 6000 rpm. 900 rwhp is a tall order on pump gas but very far from impossible. Palm Beach Dyno made 890 rwhp on 93 with a GT500 so I would suggest learning and applying as much as can be from that. I can predict what compression it would take to achieve 900 rwhp on 93 and be OEM-reliable but you guys wouldn’t like that answer. But consider for a second that a current Mercury Racing inboard V8 runs on 93 with port injection and has a BMEP of over 24 bar. The motor will run reliably at WOT for hundreds of hours. It has 7.8/1 compression. 24 bar BMEP in a coyote would put about 810 hp/640 ftlb to the wheels and be rock-solid reliable on 93.
