How Much Power with Stock Bottom End?

[Mr.Spool]

I enjoyed following this as I am also looking to turn up the wick.I have done research and experimenting with plug reading. The question that I have is how do you adjust your leanest cylinder and even out air flow?? I have my AFR pretty good on E85 Eric TT chip. it runs good when the boost first comes on but fatten up at the end. I would like to get it better across the total run. Can this be done with Eric Chip??

I have a stck block and turbo, IC, free flowing exhaust, DW 300 pump, hot wire ,adjustable fp reg, scanmaster 2.1.80 lb injectors E85 TT Chip, Powerlogger, AEM WB

Easiest way/cheapest way on a stock computer is to run the rjc plate and run enough fuel/timing to keep the lean cylinder happy,individual cylinder correction is also another way,but you need an aftermarket computer for that.there are other tricks but I'm not going to get into that at this point

You can go faster than most. If rpm is kept below 5500 it will last years. You start having over revs or have it hitting 5700+ out the back it will crack pistons. Low 10's for years. a couple of revs to 6000+ with 9 sec power and some worn wrist pin bores and the pistons will fail. They are just too heavy and the wrist pin bores are usually worn.

Thanks for the input Bison. Your advice is always appreciated!

Just for SnG:
If you are trying to "keep up" with the newer cars, the low RPM flat torque curve of the Buick shouldn't be taken for granted. That's why these cars are quick. Not the fastest, but quick enough to take money and still be respected on the street.

You still need rpm if you want to run with modern cars. Meaning it has to fill the cylinders well past 5500rpm if youre thinking of racing anything modern that has any steam. Hellcats, GTR's, corvettes and exotics. A Buick that traps 125mph in the quarter will get sent packing by these cars in very close to stock form.

You are correct as usual. I still believe most well tuned cars have a chance though, on the street, at a light, with DR's, in a 330' run, against a bad driver and radical tires. Lol.

Maybe, TR's are cool AF but fall way short these days. I took a brand new '15 Mustang GT and bolted on a hellion twin turbo kit, change oil pump gears, added and converter, fuel system (E85) and tires and that car went 150+ mph. That'll walk pretty much gap ANY random Buick.

Yeah, crazy easy and cheap power.
I am not talking about the track though, and not beating every car you line up against. These cars were never really the fastest, but one of the quickest. The street is still the equalizer, and was merely suggesting that there is a chance against the average modern car.

No they dont,with the right setup a gbody will hook harder than just about anything out there.

That's the problem with thinking like this, mph doesn't win races,and stock 15 chassis is not going to lay down the power.yes they can make power easy but will overwhelm the chassis at those power levels.i have seen less powerful cars win all the time because in real world on the street,everybody makes power,how you drive and get it down the road is the way you win races and a g body can get it on the road.

Cheap power?the modern cars can make power but have a very hard time getting them work on a real street without vht.there is no substitute for suspension,power mgmt and driving.a g body with a healthy combo and good driver has more than just a chance.

Agreed. "Cheap": I was being nice, but cheap is a relative measure.

Remember the when the 1K Supras were the craze but lost a lot of races at the track against lower HP cars? To your point: HP alone doesn't win races, but HIGH RPM HP is a lot more beneficial if someone only roll races from 70 mph.

Back to: How much HP on a stock bottom end? Enough to surprise and beat many.

GOT TORQUE ?

600 tq + 2004r + .342s + high boost at low rpm + 3300 lb mid-size gbody is hard to beat 0 to 125 which most races are won on the street will easily handle a 4000lb 1000 hp limited traction mustang

You guys are living in the past. My car ran 9.40’s at 154 (12 psi) on cheap E85 with zero suspension mods, 60’ in the 1.3’s all day long. I had that car hooking really good on the street using a boost leash.
A stock block TR isn’t hanging with that. On the street and definitely not at the track.
I’m as Buick or more that you guys, but come on. These cars are dinosaurs. They’re awesome but they can’t hang with modern cars.
As far as how much power on a stock engine....my car has a bone stock long block except springs....I’m going to see what the limits are on Ethanol. I’ll report the results.
Either way, there’s no way I’m pulling on side a blown/turbo coyote mustang. You guys need to venture out.

Actually we race every weekend,and I race a stock block buick in a wrung whatcha brung situation and a 9.4 car would barely be close enough to see my taillights.

If you think a 2015 mustang with just a boost leash and tt that goes mid 9s at the track can hang with a really fast purpose built stock block gn on a real road you need to venture out.

No doubt the gap closes on a prepped track , there are some fast stang's around my way but all these 900hp stang's and hellcats by me turn into 11 sec cars on the street, the street humble's alot of big mouths in my area. i always say this aint a dyno race or we arent on the bonneville salt flats , its who can get to that marker or parkway-under pass the quickest..
