everyone has to go with their own expeirience whether it be good or bad and not on someone else's as it may not be the same at any given time and situation.

 

As per the question of the 24# injectors and how they work IN MY CAR....my statement is one I will stand behind completely....but you have to realize that every other guys car may not be the same .  Generally speaking, though, the 24# injectors will, or should, be sufficent and will operate as well or better than the original 22#er's, especially if you do ANYTHING that increases the air flow into your combustion chambers !!  MY fuel milegage increased from 22-23 mpg with the 22# injectors and stock set up to 27-30 mpg with the 24# injectors with the modified setup I described and A LOT MORE torque and HP.....when I can get to a Dyno, I will let you know what the final increases are.

the "impressive numbers" as you call them are not all that "impressive".........LOL......my 87 Convertible is bone stock except for an air foil in the throttle body and the Hypertec ThermoMaster chip and a 160 degree Hypertec thermostat ( I personally like to run my engines cool) and I get 25 mpg around town and up to 30 on the highway if I drive it gingerly (which isn't too often!!!  The aluminum heads set up makes a difference in the 87 while the 85 has the cast iron heads and 10 HP less at production.  ANY engine runs better and performs better with COOL air and MORE of it.  If you increase the air intake into the combustion chamber and add a little more fuel , the compression at the point of ignition will all combine to burn more efficiently and create a better running, better performing engine.(assuming , of course, that you have the proper timing and spark plugs)...increasing fuel mileage and performance.  Of course, you can push a little too much and you start to go the other way as in the case of my 75 StingRay.....I built the motor up with a lot of goodies including aluminum/alloy roller rockers and solid lifters and a somewhat radical cam , blue-printed and balanced  heads with titanium/alloy valves and the rods and pistons balanced to within a dust speck of each other and the crank balanced and polished and a Melling hi-flow oil pump with a Moroso Pro oil pan, Edelbrock Performer intake and a Holly double-pumper carb and a whole lot more goodies that would take more than a page to cover.  Short story is that the motor put 418 WHP (at the wheels horse power on Dyno) with approx 450 Bhp (Base HP) and approx 460 pounds of tire shredding torque.  Needless to say I was estatic to get 15 mpg fuel milage around town with a built-up TH400 automatic transmission and beefed up 2:73 rear end. Would it be too much for you to believe that C5 and C6's (not Z06's) "fear" me???  Mustangs run and hide....

 

The 85-91 L98 TPI engine is the perfect testament to the great minds at Chevrolet.  It was an engine before its time and remains a perfect engine to play with and get good horsepower and fuel milage without going to extremes and without spending beaucou bucks.  It remains one easy to work on by DIY'ers yet has the computerized mechanisms that compliment for better performance levels.

 

Okay, here I go getting carried away. I'm an old gearhead that doesn't know when to shut up!!

 

 You all have a good evening.
