Alright, finally got the video made and uploaded. This video is the first start of today. It was 40* outside and the truck had been sitting for about 12 hours since the last time it ran. It was not plugged in overnight and I did not touch the manual glow plug over ride during this video. This...

Regular old Bosch's, not marine's or different pop pressures..... Plain Jane Bosch's.

Hey all, been awhile since I posted or even been on the forums. I've been busy moving from GA to KY, but I am finally getting settled in a little. I am having a problem with the 94 in my signature. It isn't starting so well lately. It is colder here in KY, about 40 or so the last couple...

When you're going up the grade and it loses power..... does the check engine light come on? What I am thinking is this..... If it really is getting to 12 psi boost with a stock program, the ECM is going to defuel and set a code for over boost, in other words you are definately going to lose...

Random acts of kindness will come back around to you some day.

My 4-wheel drive burb weighs 6,880 lbs. Leroy's is the same year as mine but a 2WD, so his is a little lighter.

6.2 N/A engines came stock in suburbans and blazers (and of course pickups) during the 80's and possibly very early 90's. Once the 6.5 came out in 93 or so, the 6.2 was gone in the civilian GMC / Chevy trucks. Anything Chevy / GMC diesel after 93 was a 6.5.

Search on youtube. Lots of exhaust videos on there, you can hear several different brands and make up your mind on what you like.

I think you just asked.....

Ok, here are the new calculations based on a 4L80E, 235/70R16 tires (which are 28.95" tall), and 4.10 gears. 3rd gear at 60 mph would be 2,855 RPM 4th gear at 60 mph would be 2,141 RPM 3rd gear at 65 mph would be 3,093 RPM 4th gear at 65 mph would be 2,319 RPM Switching to 235/85R16...

Bill, It looks like your truck might not be shifting into 4th gear......If you are turning 2500-2600 to go 60mph. These are the RPM's you should be seeing at 60, assuming that you have a 4.10 rear axle and tires that are 30.5" tall. 3rd gear at 60 mph would be 2,713 RPM 4th gear at 60...

You will find post #8 helpful: http://www.pirate4x4.com/forum/showthread.php?t=79854 Here is a little info on the turbo.... http://www.4btswaps.com/forum/showthread.php?907-4BD1T-amp-4BD2T-Turbos.

Peak efficency is at or very near/slightly higher (200 RPM) than PEAK TORQUE RPM on diesel engines, and follow's true no matter what size or # of cylinders......... At least that's what I have always been taught and always read......However the peak torque RPM is going to change for different...

Ok.....Now I get it. I was under the impression that you were reusing the 4L80 and old suburban rear, so I couldn't understand why you guys were discussing gear ratio changes in order to get the new engine to cruise at the same rpm that the 6.5 did......

Yea, I wish I would have known that you had these or looked at your site again before I ordered my S&B on Friday...... Sorry about that.

Leroy, you said you are reusing the 4L80E and the current rear end in the suburban right? The only thing you are changing is the engine?

I like the idea a lot. ......... I think other "big truck" stuff on it woul help offset the look of the huge hood and front fenders. West coast style, or at least bigger than stock, mirrors, stacks, 19.5 alcoa's, etc. Fix the license plate in your photoshop pic :D

I just ordered a S&B intake a few minutes ago. It's going to replace my factory flat panel setup with a dirty paper filter in it, so I SHOULD notice a pretty big difference.

Just ordered the S&B intake..... More to follow once it arrives.

Yea, that isn't hard to believe..... Our Heavy Equipment Transporters have electronically controlled 8V92's in them that are rated at 500 HP from the factory. They aren't "maxed out" programming or injector size wise either, so more power wouldn't be difficult.
