when you tune you always start with a stock bin file. cause what works for my engine 75% of the time will not work for your engine. they all have their own needs. why canned tunes suck so much. its not tuned to your car, its a tune that has worked on other cars from a in car tune.
never did the back brake up grade, but iirc you need 17 inch wheels for it.
ported stock manifold flow no where near as well as any set of headers you buy.
you cat back is good to 300 + hp, your not even close to that yet. if you do go full 3 inch tho, it sounds damn good. better then slapping after market mufflers on the stock cat back.
hp tuners you need to buy credits to unlock your year car. cheaper to just unlock "your" car. not the whole years worth. this is on top of the cost to buy the interface. so it gets up to 500 easy.
and your in IN, you got e85 all over dont ya? your best bang for the buck is a high vol fuel pump, fuel pump rewire some 60# injectors and a 3.0 pulley. enjoy the free HP. add cam and then a tranny with some hardened parts cause bye bye tranny.
Yeah, I totally understood the "stock bin", just have read many articles on here of a "starting point" bin file. You recommend nixing this idea, back up my stock file and go from there then?
As for E85, it is cheaper, but I also have access to 93 octane at several locations. Not so different from 92, but the many companies that offer are said to be decent.
As for HP, it's "estimated at about 280, but this was GPS for now, have yet to hit dyno, but will just prior to serious mods. There is a tuner group in Noblesville, just a couple miles away that have a dyno, and price is reasonable. Since Kenny Brown performance moved away from Clermont Indiana (near Raceway Park Drag strip), I don't know many others. Shame my older brothers income went to his head, we aren't at all as close as used to be, but I respect him all the same, being self made in his industry and knowing (cars top to bottom, as well a foremost suspension expert) I was hoping to get input/help from him since we both think similar in the "clean smooth" no bling concept, but he isn't fond of the Regal. So, screw him, in fact, once I get things sorted, I've a standing bet with him and his new Ferarri powered Astin, which he dubbed a "low 13 sec car". He claims I'll never see better than low 14's, but I've already blown this theory.
I've read many a article on trannys, and it's nice to have friends like those at Coan in Kokomo, where I grew up. Did a lot of work on previous muscle cars for me and my Father-in-Law worked there as a CNC operator.
Although, I am seeing a few things I can do myself, as well, Paul the tranny guy listed on here is in Ft Wayne (my birth city), just a bit over an hour away. I have the HD trany, was going to do axle shaft upgrade as I know one is showing wear (as my usual mechanic named it 40mph wobble) especially in a right hand curve at that speed. Tells me it is right shaft. With just over 200k, it's time soon enough. I've also a retired fireman school buddy that did trannys in his off time, he is pretty good as well.
Long term goal is anything over 300Whp and possible very low 13's and even high 12's which I am told can be done, especially with the right parts, Gen V S/C, good tune and some semi sticky tires. The tires will be a no brainer as we have tested for Hoosier tire for over 20 years, from way back in the SCCA days, as well, run them on our Duster. (pic) it's a single carb, no power adder 528 cu.in. just over 900hp and 925 ft. lb. torque at wheels. Not bad for a dated ladder bar car.
I can build anything, but will admit, the computer tuning age is still a "learn in progress".
So, headers? any brand/brands preference? 3" exhaust is definite, and parts are waiting once brakes done. Brake upgrade? F-Body seems popular, but is it much better than a Impala SS upgrade? Seems the Impala bolts right up, no need for sleeves or any drill and tap. Many different opinions here.
As for rear, was looking for that "one touch extra", even though the majority of stopping is front, a little more as I am into it, can't hurt. So many different opinions there as well. I am hoping once the suspension is complete, I can at least hit a road course for a little fun, not so worried about being that competitive, but that would be an extra if it comes, as back in the day, when my brother and I did have a better relationship, we were well known in the Porsche arena, now he is more vintage. A 64-1/2 427 AC cobra from Superformance that has been tweeked with some SVT help and kills most of their cars on track. A Donovan prepared factory "re-certified" 64 Jag E type, a little over 450hp from a inline 4.0 liter 6.
Then there was the GT 911, 625 Bhp with a lot of development and our own proprietary engine being a 3.67 liter normally aspirated. Started in 1992, and retired it "for now" in 2008. It will receive a face lift back to the slant nose body and be back on track in historical events, along with the Jag.
Back to the Buick, subtle body effects, rims/tires, and duals wil be the only "give away" aesthetically, but the performance I am hoping will be the show stopper. Not looking for any records, just a good daily driver (fair weather) and quick enough for some bragging rights and a few "damn that thing is faster than I expected", as I already get from many Mustang GT owners I know.
I've soooo many questions, I am sure I can find lots of answers, just looking for good ones, that aren't going to "break the bank" totally along the way. That and from any who "know, cause they been there"
As for pulley size, I wasn't planning quite that aggressive, as I've read manny posts that with a GenV, if no cam, 3.4 to 3.5 was smallest recommended. I think I found this info on either SLP or ZZP.
Looking at their stage packages, I am setting the goal between stage 3 and 4, really didn't want to pull motor to do cam. Felt 1.8 rockers with throttle body upgrade and slightly larger injectors might fit my needs.
I've read many things on Michael Daugherty's mods and setup, but my Florida guy, Robert (also member here) claims he gets over 300Whp without quite as much work and cash outlay.
