I keep trying to get the car to launch at least WOT by second so I can recreate for Lund the detonation ( audible and PCM) in a log that was wrecking my first 2 engines by being WOT full throttle in 2nd gear shifting to 3rd...( thats when the first 2 engines would detonate and blown up).
I cannot using traction control because this will pull timing more than even the trans tq protection to get them an apples to apples. In addition pulling timing to low especially on the shift with this blower at full boost but low rpm sends the cylinder pressure thru the roof and imho is a major contributor to blower its counter productive to the entire reason to go less boost and lund. I have gotten 3-6th so 3rd gear up to like 120mph but that was never the area that blew the engines..so the 2-3 is the last thing to wipe off our list and say ok we done it, as successfully addressed what was blowing my engines....
So the first time, I put it into sport and used the paddle for 2nd gear and slowed to a stop. I've done many second gear roll outs but had no put it in while rolling then STOP....as I was preparing log and self to handle this wild mofo...I didnt realize it had dropped itself to 1st and I should have that's on me entirely, imho the first mistake ever made by me that led or could lead to failures....it instantly went to 8k I gave it D and let off...BUT that pill that delays boost also delays the bypass opening, figured that out in this log....it was so fast to 8000 I cant even describe it like seemingly less than a second...
The additional time was doing same thing but being at a stop rolling out hard enough to transfer some weight in 2nd manually stabbed it at 45ish instantly got insane gave it D ( works faster than paddles and if it was a successful 2-3 at WOT i would have tried to stay in it for log) it tried to shift you see it change commanded in log but it was spinning SO hard it overshot the rpm and bumped it but not nuts like the first time......
I have no doubt the first one would have killed the engine had I not had OPGs it's the precise scenario that does break them....
Car is just nuts its actually making more power than it should and showing a little more air, load, boost than it should ( I'm using a 3.70 griptec pulley till my 3.75 Edelbrock comes in)....
I agonized over pulling a brand new engine apart to do the OPG/S, I thank god I did now....
Lund has sent me a 2nd gear leave tune.....and I may just have to put my drag pack on, I was trying to wait till right before racing because the 305 45 17 MT SS ( I've had about 10 sets since they come out ) seem to be best the first 8-12 hits...but I may go ahead......
Car is useless as is lol....
I blame others when it's their fault and Ford themselves this one I shoulder blame however I'm desperate to KNOW if the 2-3 shift blow up issue is gone and get closure to move on after 3 engines in 2k miles...this one has already received more load than first 2 combined...so if its popped then I'll use some drop in forged pistons and new block..I cant be mad this time......
I cant afford it right now but I have my second core which I caught early and plan to build it regardless how long this one holds our or not....
I inquired to Edelbrock if I could get a 10% over outer 8 rib for my fancy $910 2 piece harmonic balancer which comes with a 15 over so I can drop boost ( as I already have the slowest possible pulley on blower ) but they dont make it....contacted them Monday I think it was....
