Quote from: keith71 on February 21, 2024, 05:53:02 AMI bought new in 1999 a chevy S10 pickup truck 2wd 5 speed.. It had the 2.2 LN2 4cylinder engine with a whopping 120 HP @5000 rpm with peak TQ of 130 ft.lbs at something like 4200 rpm (cant remember the tq number exactly.
Anyway drove that truck 100 miles a day roundtrip.. It averaged 18-20 mpg whether my foot was to the floor(which it always was with the anemic 120 hp and 3900 weight of the truck) Or gently cruising down the highway @60-65mph..
So in 2009 with roughly 65-70 k on the odometer..
I Fabricated and built a turbo charger for this truck using a T3-T4 turbo, (little to big) At 75000 miles I promptly broke a ring land on the factory cast piston at only 6 lbs of boost. (had hoped to raise fuel pressure and add fuel the easy way) It was not enough.
Out came the engine Wiseco forged pistons, Eagle H-beam 4340 con rods and Mls head gasket were all installed..
Now the fun part.. I purchased efi live, (same as hp tuners) It is a tuning software that is used to change 90% of the 250-300 tune parameters that are stored in the factory ecm. I needed to use and be able to tune factory ecm due to emmission regulations in the great state of CT. An aftermarket ecm would have never passed emmissions.. These are obd2 ecm's that started in 1996.
I started slowly adding fuel to the tune and reducing ignition advance while closly watching my AFR gauge.. At 12 lbs of boost and 5200 rpm the injectors could not give anynore fuel(stock 17 lb/hr) So it started getting lean despite increasing the pulse width a ton. but the engine mechanically was okay with almost double the horsepower.
So I Added 30 lb injectors requiring another adjustment on the injector tables in the ecm to compensate. And a smaller T3 turbo with a smaller exhaust AR housing provided nearly instant boost at 2000 rpm. But would run out of airflow at 20-22lbs and 5700 rpm. (who needs to rev that high in a pickup truck anyway)
At 18lbs of boost and 12.6 AFR I had a little sleeper rocket as I called it At about 300 hp at the wheels it was fun to pick on unsuspecting stock camaro's and rice burners with those fart can type mufflers. They make alot of noise but dont really do anything.. I had 100% stock exhaust from turbo down pipe to the tailpipe. Very mild mannered and pleasant to drive with boost building slowly with rpm just driving normally. Zero lag from the turbo. The T3 was sized just right for a daily driver.
I also got a few more mpg's with the turbo believe it or not. If I was driving normally. I believe because I only need 1/4 throttle to cruise down the highway at 65-75 mph instead of my foot to the floor with stock engine just trying to keep up with traffic. I drove that truck until last year. It had over 200,000 miles on it with 140,000 miles of those with the turbocharger. She has finally started getting some blowby enough that the biggest catch can they make was 2 quarts to small.It will puke about 2 quarts right out into a catch can in about 6 seconds at 20 psi. lol. yep she is tired now.
Suppose I could bore it 1mm over new wisecos and drive her for another 100,000 ?? . I doubt it now, it is retired..
I know totally off topic but I was just reading about your adventures with your straight 6 and it brought back some memorys..
Quote from: keith71 on February 21, 2024, 04:51:43 AMLove to hear the condensed version of what your up to now with your Carbureted (yuck) (joking) lol 300 inline 6 .. I only remember the holley sniper efi, which I know was terrible for economy and performance to a stock holley 390 cfm carb?? Among other issues with the sniper.. I hope you go back to efi with another system instead of any holley type..
Iam sure you are aware of the late 80's early 90's GM ecm's.. People have been adapting those things to lawn mowers to trucks.
Their is also megasquirt, which is ok but getting $$$
Also there is now speeduino ecm, which is adaptable to anything 1 cylinder to 12 cylinder. Both of these would use all factory ford efi parts and the factory efi harness that came in the ford efi trucks with 300 6 cyl.
Speeduino is open source as well as gm ecm's from the 80's. using gm ecm bins with full open source data logging from tunerpro.. 7747 GM ecm from late 80's I believe is a good one. Have you checked out a forum called Gearheadefi ? these guys have been tuning and installing these ecms on everything for 30 years.. I could go on and on.. Was just wondering what you re doing with your inline 300 ford? I felt bad when I read all the trouble you had with holley sniper. So knew you were not to happy and did not want to piss you off anymore with any other suggestions cause I know you tried them all..

Thank you

What about Gary at DES in Kansas ? As of about 2 years ago he still had some 6/1 and a few 8/1. He is very well respected in the Lister clone and many other diesel engines.. Is also a fairly large parts stock for these engines.. Was not sure if you were aware of him or not? Good luck on your project.. Ha, my name is Keith as well..
