Project Boosted

[72 sub]

Very Nice !!!!! Really cool that you made it up to the show in Qualicum (our neck of the woods). I missed it this year as we were down island .

[sandking]

Wow, thats nice!! Maybe I missed it, but what is the name and brand of the grey paint?

[Yukon Jack]

Very nice and congrats!

Are you going to bring the Blazer to the Greenwood show this weekend?

[SNEAKYPETE]

Been awhile since I posted, got the jimmy all done, still needs some final tune work but it hits about 10psi, almost no turbo lag. Dyno'd 419hp, 492tq, did it in fourth gear and pulled to about 5600rpm, hit a 150mph. Needs gears in a bad way, I haven't even used fifth or sixth. Have a narrowed up nine inch built and ready to be installed 4.56 gears, detroit, disc brakes and a set of mickeys 29x 18.5. Cant wait, this thing is a tire killer right now.I have been terrible about taking pictures but here are a few more. Ive got about 2500 hard miles on this rig and it is running amazing, puts smile on my face every gear.

Looks great to me .

I like that color - subtle and different.

Here is a pic of whats coming next.

[Yukon Jack]

How soon until you start on this portion of the project?

[SNEAKYPETE]

As soon as I finish collecting all the parts. I need to find some stock rally wheels to send in and get my 15x14s built, dont want to send mine in because I want to keep driving it. Just need ebrake cables, wheels, master cylinder swap, driveline and time.

I know it's been a while but any more updates? Get the rearend and stickies in that beast?

And, nice to see you are in the PNW.

[SNEAKYPETE]

The plan has changed a bit since I last posted, I put 4.10's and a posi in it for last summer, the narrowed up 9" is going in real soon I need to build my new trailing arms and do a c-notch but I sold the mickeys and am going to run a little more streetable tire. I love driving this thing so much that the pro street tire isn't a wise decision, I am going to do a 29-15.5-15 mickey thompson st, it will hold up alot better for all the street driving this thing sees. I am waiting on my new seats to arrive I ordered a set of sb bomber seats and a custom rear bench from Eddie Barrett seats, I recently had a baby boy and can't wait to get him out on the road with me, been a bit lonely driving around with no family so the seats are going to be my favorite upgrade

[SNEAKYPETE]

A few more things done on my jimmy, stripped and painted the complete underside with por 15, new front springs and balljoints, new front swaybar, built some new trailing arms, installed my narrowed up 9" with 4.56 gears and detroit and rear disc brakes and c-notch. Now all thats left to do before I can drive it is rear shock mounts and build my new seat mounts. I am super stoked to drive it, its been about 8 months since I drove it last. It has been quite the project the last 3 months.

[SNEAKYPETE]

a few more, finally I was able to wash it off from 3 months of grinding dust and dirt.

[SNEAKYPETE]

Looks sweet! How about some side shots?

[thor]

those deep dishes on ther rear look sweet!

What was the reason for the 4.56 gears with the turbo setup. Most turbo rigs that I've had experience with like a higher rear gear to load the engine and spool the turbo better. Granted with a T61, you should have NO problem getting it to spool.

[SNEAKYPETE]

The reason for the 4.56 is the double overdrive the t-56 has I wasn't even able to use 5th or 6th, when I went from 3.07 to 4.10s last summer that let me use 5th and I got a good deal on a third member with new 4.56 and detroit so that made the decision for me. The turbo has very little lag time and with the lower gears it really comes on strong and quick, makes it a real blast to drive.

[Wasted Income]

That makes sense to want to be able to use every bit of that T56.

Funny how every setup is different. I'm geared at 3.73 behind a 4L80E, and my truck felt lots stronger at highway speed when i went to a 28" M/T radial from a 26 M/T radial. Didn't really notice much additional lug at low speeds, and the turbo lit a little sooner.

Pretty sweet rig you got there.

[SNEAKYPETE]

Here are a few more progress pics, I am getting alot of body flex and squeeks with the new suspension mods so the plan is a full tube structure and removable rollcage to eliminate flex and make me legal at dragstrip, here a few pics, the plan is to cut out rockerboxes and tie all mounts to the frame, modify trailing arms into an adjustable 4link setup. There will be alot more triangulation in structure and another lower door bar, rollcage will be easily bolted in for a quick trip to the strip.

Im wanting to put the t56 in my blazer. what position is your shifer in? what did you use for a cross member? and any more info on your hydro clutch set up would be much appreciated. Sweet jimmy too!!

[SNEAKYPETE]

My shifter is in the rear location and i built my own crossmember bolted solid to trans and is bushing mounted at framerails. It has a stock internal slave cylinder and i installed a hydrualic master and a stock pedal mated to it.
