Yeah, the next step regardless of hp/tq will be built motor and transmission upgrade. My future goal is to have 750-850whp .. Ill go the max before having to change all gear sets 1-6.
Glad you got some great numbers out of it. With 661 AWTQ on a stock block, I would be way paranoid but I'm overly conservative because I can't afford for my motor to self destruct. Best of luck with your future build.
661 wtq on a dynojet.. It would read much lower on a mustang, which i assume what most people refer to when saying 600/600 is max on stock motor/trans.. Am i right ?
Hahaha my car takes 2 tries sometimes to start... the beauty of E85 I would recommend Lucas Ethanol Fuel Conditioner for you majj, i use it all the time with E85 and it helps cold start and keeps IDC and STFT at good levels.
Your right about avg in the mid 600s on a Dyno jet, as most guys on mustang dyno fbo with out intercooler are at about 580hp-590/570-580 ft lbs readings from what I've known locally
Curious and worried. I know most say 600/650 is the limit on stock trans, I'm assuming those are mustang numbers. When on e85 I'm at 660wtq (dynojet), is that safe?
600/600 is the widely accepted limit on a stock motor - after that the rods are at risk of bending. I'm overly cautious and would be a little uncomfortable about being right at the edge and trusting it to a difference in dyno readings. But your results may vary. If your tuner is comfortable with your numbers on his dyno, then all is well I guess.
Majj, congrats and thanks for the post. Helpful for me because I'm doing similar mods on my 2015 in 1-2 weeks. I have to wait for the AMS downpipes that are on backorder.
I was unaware of the e85 start up glitch in the cold. Shouldn't be a big issue for me since I live 40-50 miles from the nearest e85 supply, but still want the option.
Also interested in the tq limit of the tranny.
I'd appreciate it if you'd let me know if there is anything you would have done differently.
Great numbers. I just went FBO e85 and even here in Florida on a cold start it sounds just like yours.. I was worried too but I guess it's normal.. I'll be looking for an intercooler myself!
