Thats cool man, I was just curious, I couldn't ever go over 7-7.5lbs with my 112. Trying to figure out what my next purchase needs to be.

 

On my '05 Silverado SS I was at 7.5lbs with a 3.0" pulley and 112. It also had headers but, that was it.

You could get an overdrive crank pulley, that would get you some more blower rpm.

 

h'mm..........mine wasn't happy floating wise around 5600 rpms from what they said...

My truck has a 2 bar map and the MAF connected but that definetely took some work, my VVT is disabled also, gave some major headaches first round of tuning...

 

When should you start worrying about valve float running that many rpms on a stock cam/springs?

 

You know I thought that was too much RPM as well, why it makes so much power up top and the engine has no issues with valve float.
So, I verified the RPM pickup on the dyno with hptuners and they very close, off a few rpms, but nothing to post about.

both the TVS Tahoe and this TVS Sub along with the 383 TVS we did, all pulled above 6500rpms with no problem, two of them with stock valves.

I know it's wierd.

 

I already sold my 112, I just need to take it out of my sig now lol.

 

Damn nice!! Can't wait to see the results of a lil bit of VVT tuning on one of these

 

Ouch, hopefully mine will turn out higher. I actually got more TQ and Power from a heads, cam and headers install. I'll be pretty disappointed if mines not 500rwhp or better with a 2.8 pulley on TVS 1900

 

this was on 5 psi of boost, thats nothing to shake a stick at.

 

I'm sure it will, all the TVS kits we've done have been impressive.

I'd like to see a 5.3L with some heads, cam and good exhaust make 500hp.
I wonder if 10psi would get it there.

Yours will have to be there!
