Detonation.

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

Ouch!

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

You might want to install a wideband O2 sensor on that new motor. Shes way leanin out.

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

Lol, ok.

You mean this here wideband?

http://i44.tinypic.com/2eapeg0.jpg

Trust me when I say, it was most certainly not too lean.

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

Lol. I think perhaps it might be a question of the owner not wanting to loose in some of those exhibitions of speed in "Mexico" ?? Haha you have to enjoy the giggle factor. .. even if it costs an ls motor.

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

This guy. This guy gets it! haha :metal::lol:

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

LOL Next short block please....maybe we should dial the boost back..... NAH more is always better :devil:

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

So whats your CR and boost level?

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

Hey, what can I say....I'm greedy ;)

CR before or after the kustom connecting rods mod? :lol:

Compression is 9.6:1, boost level was 15-16 psi with some spikes to 18 psi at the shifts....
I mentioned it in another thread, but "boost level" means nothing. 20 psi from a china ebay 60mm turbo is not the same as 20 psi from a PT106.

I'll probably start piecing together a forged shortblock for it, but for now, in goes another junkyard 6.0. :chevy:

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

As you probably know, predetonation has nothing to do with the strength of your bottom end and everything to do with CR, boost level and fuel delivery. Thats a relatively high CR and alot of boost. You need proper Fuel delivery and timing or it will be quick curtains all over again... pronto. An air to air intercooler would make a big difference as well. Or...How about a methanol injection system?
Even if you dont care about grenading the motor, you will get a Huge performance increase if you take care of the predetonation.

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

Tom, I appreciate the advice, however I've already got most of it covered.

Fuel delivery is up to the task. I have a Fuelab 41402 160 gph pump, fed by a -10 sumped tank, which splits to two -8 lines before the fuel rail, and 80 lb/hr injectors. It never...never...went lean. I have lots of logs showing that the fuel system is capable of supplying the correct fuel pressure and AFR even at 16 psi and 7000 rpm.

I don't have room for an A2A intercooler, with my AC stuff in the way. I do already have a dual nozzle meth injection setup on it.
I circled one nozzle, and there is another one on the back side of the pipe that you can't see. I am also running E85.

I plan to upgrade the bottom end, since high cylinder pressure, whether from big hp, or detonation, bends rods. The stock cast pistons also don't give much room for error if you get a little too greedy or get some bad gas or something.

I've built and ran two other big turbo LS motors in the past, and never broke anything with them. Once I hurt this one early on, I didn't really care about it anymore, so I just kept turning up the wick on it to see what it would take before it came unglued...which it never truly did. Call it a science experiment :lol:

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

I am still betting on predetonation. Mighty surprising with E85 Ill admit. Do you have a custom tune on it? If you dont, Id get one. There should be someone close enough to you with a dyno and flash capabilities.. not cheap, but thats what I did with my Mustang and that did the trick for me.

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

I own a commercial version of EFI Live, and have always tuned my own stuff on the street and on the track.

The Blazer however, has a Megasquirt ecu on it, and does not need to be "flashed" in the traditional sense. I can tweak fueling, timing, boost values on the fly and it changes immediately.

Just a friendly heads up, but there is no such thing as "predetonation". I think you're combining two different things.....pre-ignition, and detonation.

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

Lots of NMCA and NMRA racers running 12-1 plus compression with high boost levels(30psi+)
With the stock bottom end there could have been any number of contributing factors.
I am sure you will have one hell of a beast when you are done!

Hmmm, wintertime upgrades??

Stay tuned.

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

tease....:sexy:

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

Those stands are a really simple cool idea.

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

They'd be great for changing body bushings. Damn, that reminds me... :(

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

I have a friend that uses the same ones, and he explained that you get to see/work on the vehical at ride height. For those of us that have low ride heights these stands work great.

"Cribbing blocks"

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

Yea, needed a way to get under it and work comfortably. Plus I hate jackstands.

The other project truck is hogging my lift... #firstworldproblems

That's sweet! I think you are going to have to redo the cold side, ;)

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

Nice.:metal:
Please post up some more video of this thing when your done.Really liked your last ones from "mexico".
Such a cool blazer.

WOW! That could very well be my fav. mill. Very,very nice

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

What is the intake on that engine from?

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

WOW Clean!

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

Too funny!! #firstworldproblems hilarious!!!

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

Haha, you guys are killing me...I don't know how I missed all these responses :lol:

Thanks man.

It's a Holley Hi-Ram

Thanks.

;)

Got the bullet back between the framerails.

Hey...look at that, another upgrade for 2014 :metal:

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

I've been looking at the Dominator ECU for an upcoming project, I am eager to hear your impression of it.

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

Motor looks great sitting in place. .... For the last time? Lol what are the specs on this one? I think the Giggle factor has been turned up a few notches. You have to love Holley for their Ls stuff

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

That's bad a$$ Bro! I'm getting ready to drop some $$$ on a this for mine:

GM 265mm Pro III 6L80E Torque Converter
http://circledspecialties.com/p-107-...converter.aspx

Thougts?

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

Yeah, I'll report back. I've tuned lots with the stock ECU, cut my teeth on Megasquirt, and now I really like the software and capability of the Dominator. Looking forward to trying it out. Definitely a little more pricey than using the stock 0411 ECU. lol.

Yeah, they are on top of it. Probably not the last time. Another stock shortblock for now...gonna sneak up on the tune a little slower this year, while I'm planning what I want to build for a forged shortblock.

I like it. I have a Yank now, but Circle D is definitely on my radar...but the Yank works really well for me.

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

Nice parts, looks like fun.

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

Impressed as usual.

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

Bumpin' for an update! Curious to see your thoughts on the Holley Dominator! Awesome build man...super classy and really well executed!

Re: Project Family Truckster: 2wd Conversion Turbo LSx Blazer Build
 

Not much new....balls deep in wiring. I could have had it up and running in a day or two, but I'm pretty anal about the planning and execution of the wiring. It will be super clean when done though. Also been splitting time with the blue truck project.

Thanks for the compliments.
