Have not. GT2-3 cam is awesome though, feels like it won't ever stop pulling and MPG is unchanged. Idles and drives like stock. Not a lot gained below 3000rpm, but after that, it just starts pulling like crazy. You can probably pick one up on here or LS1tech for cheap used. I run mine with LS6 springs, as that is what lingenfelter recommends.

 

Ever had that tank at the track?? I wanna know the timeslip!!

 

Grocery getter hasn't seen the track yet, have to put wheelie bars it on first

 

Thank tx for response, what about did u gain with cam addition ? And no chop at all with cam ?

 

No chop at all while idling, exhaust sounds much nastier though when you are on the gas, especially at startup. I get lots of looks when I fire it up, it's a perplexed "did that sound just come from your SUV?" look.

Gains on boosted applications with the GT2-3 cam typically add 40-50rwhp and I don't doubt it. Haven't put it back on the rollers yet, soon hopefully.

 

Thank tx for replies it helps a lot.

 

Happy to help. Do a search on here and LS1tech for the GT2-3 cam. It has been a very popular boosted cam and there are lots of videos and threads about them.

 

I'm running a 2.8 pulley with a 216/224 .551 on a MAF sensor tune.

Here's a sound clip with my first start up:
GMC Sierra MP112 - YouTube

 

How are you still on a MAF tune? I'm at the cusp of blowing through mine with a 3.0" pulley. Also, what are your IAT's while cruising and at WOT and what's the outside temp?

 

No kidding, I had to go SD when I put the 3.0 pulley on mine, with the same cam. Maybe the 1.8 rockers were the difference?

Unless he's shifting at a lower rpm. I shift at 6400 rpm.
