Merc Dr. Posted March 18, 2009 Report Share Posted March 18, 2009 (edited) Look to the bottom for mod updates! This weekend March 21-22 Spike is replaying the LS rebuild episode part 2. They dyno the motor after refreshing it. They also try a new cam and lifters to see what power it develops.

2006SilverSS Posted March 20, 2009 Report Share Posted March 20, 2009 Do you know what time and show it will be on? I know they have the powerblock, but a more specific time would be kinda nice. Quote Link to comment Share on other sites More sharing options...
Merc Dr. Posted March 23, 2009 Author Report Share Posted March 23, 2009 Sorry I didn't get back to the site before the show to answer your question. If you stillwant to see it there is a way to download it on iTunes. I found it on the "horsepowertv.com", but you can probaby find it on iTunes as well. Recap: Stock LQ4 out of a'05 GMC 2500 series truck Rebuilt(freshened) and installed a Sprectre intake, electric water pump, CAI, long tube headers, and a custom tune. 386HP/396trq. Installed SLP 1.85 rocker arms, new Comp Cams "beehive" valve springs, and new cam(240 Intake 224 exhaust 112 seperation) for 411HP/Torque not stated(looked like 390). They did say the torque dropped off which is a normal trade off for horsepower. Quote Link to comment Share on other sites More sharing options...
Merc Dr. Posted March 25, 2009 Author Report Share Posted March 25, 2009 Part 3 is this weekend 3/29 at 10am central. They are just installing a FAST intake and dynoing it to see if they can get more power. I'm sure they'll review the entire build for anyone that missed it.

Merc Dr. Posted March 30, 2009 Author Report Share Posted March 30, 2009 Part 3: Installed Fast intake, "Big Mouth" TB, 24lb./4hole taller injectors, bigger fuel rails, reprogram PCM for add-ons which included changing the timing 10*. It sounded like a shop vac with all the air it was sucking. It made 430hp/405trq. on first pull. As the computer adjusted itself after a few pulls it made 514hp/481trq! All of this with no cyl boring or head porting. Quote Link to comment Share on other sites More sharing options...
2006SilverSS Posted March 30, 2009 Report Share Posted March 30, 2009 I missed it again. Tried to find it on hulu.com but no luck. I'll check out horsepowertv.com one of these days Quote Link to comment Share on other sites More sharing options...
Fireman31 Posted March 30, 2009 Report Share Posted March 30, 2009 I saw it yesterday, I am impressed....that cam lift is only in the .530 range, and it made over 500hp! Quote Link to comment Share on other sites More sharing options...
delay18 Posted March 30, 2009 Report Share Posted March 30, 2009 I watched it as well. Did anyone notice that they didn't even mention anything about water pump interferance with that intake? How come, I thought that that was a major drawback to these intakes?? Quote Link to comment Share on other sites More sharing options...
vmaxman Posted March 30, 2009 Report Share Posted March 30, 2009 that 500hp was without and accessory drive also Quote Link to comment Share on other sites More sharing options...

They didn't mention it because there isn't an accessory drive on that motor....and they used an electric water pump for the dyno test.....

vmaxman Posted March 30, 2009 Report Share Posted March 30, 2009 yea i was just sayin that with power steering pump and alternator it would not have made quite that much power Quote Link to comment Share on other sites More sharing options...
delay18 Posted March 30, 2009 Report Share Posted March 30, 2009 They didn't mention it because there isn't an accessory drive on that motor....and they used an electric water pump for the dyno test..... Well I understand that. My point was that they do these show for to it your self guys and they show a budget build, yet they neglect to mention potential problems when doing the build in the real world.

vmaxman Posted March 31, 2009 Report Share Posted March 31, 2009 true when using the fast intake you have to custom fab some of the brackets or use the accessory drive of an f body Quote Link to comment Share on other sites More sharing options...
Merc Dr. Posted March 31, 2009 Author Report Share Posted March 31, 2009 Even if it drops the numders by 50hp/50trq, you're still looking at a 100/100 gain from stock with about a $2000-2500 investment. It costs $6k for a SC to get about 150hp. Quote Link to comment Share on other sites More sharing options...
