Did they do this test on Vinci's dyno? In the previous month's issue, they did rockers on that truck at Vinci's and the gains were very believable and respectable. I'd be curious to see how the numbers compare to last month's issue.

Did the article also say that the gains were at the same rpm everytime? I bet they did a little tuning in there somewhere.

 

I just did a little more reading and caught the part where they said the testing was done at Grantelli. I guess the guy at granatelli knows where the magic **** is on his dyno.

 

I made this same thread earlier yesterday and the mods moved mine to the general section. Good to see we are keeping up with the latest even if the facts may be a little skewed I would love to see some real dyno results on those wires. My guess would be 5 to 7 horse gain at best.

 

Grantelli parts + a truck tested on a Grantelli Dyno = Big HP gains. That's interesting.

 

All the mods listed are what pays for the bullshit they spew. Its all about the advertiseres in their mag!!!
I can't beleive they did not install a TORNADO in the article as well!!!!!

 

i gained 250rwhp when i swapped in a good spark plug for a broken one

 

Kinda reminds me of that episode of 2 Guy's Garage where they did a CAI and Hypertech programmer and got like 50 hp out of it, and it was a gas engine not a diesel. The bad thing is people go out and buy this stuff thinking they'll get similar gains. Hell, I was gonna get a Hypertech and was considering a Granatelli before I joined this site.

 

Most manufacturer's claims are inflated. From hp/tq to flow #'s etc.

 

The article in last mo. issue, they gained 21rwhp with a set of crane gold race 1.8 rockers. I think they also installed better push rods and tuned the truck just enough to accept the newly found power. I'm thinking 4 or 5 deg of timing and some a/f ratio adjustments...I don't know! I have the issue. I will read it again here in just a min. and give ya'll the skinny. If you want me to.

 

Yea i just saw this i cant believe it,

now maybe earlier in the mag i can beleive the 10hp and 13tq from a CAtback and K&N filter kit.
