Race Proven Motorsports: Cam Testing At Hendrick Motorsports Last Tuesday-Friday I was out of the shop. I was delivering a TT C6Z to a customer in NC and i also had to go over to Hendrick Motorsports for some Cam Testing.
Hendrick had called us a few months ago to order our RPM B3 Cam for Rick Hendricks personal C6Z with a YSI. They just got finished building the engine when he called us so we could come down and compare a cam GM gave him to try. We get there and the engine is on the engine dyno already. They added a second fuel pump to the setup they had. One wasn't enough. They had their own tuner there that does alot of tuning for them. The first test was with the GM cam. It was making about 850ish the first day. Air intake temps were at about 185 degrees
. I brought a meth kit down with me because i figured they would need/want it. We switched over to speed density and installed the meth kit the second day. It brought AIT's down to about 50 degrees. The best pull the engine made 947hp and 792tq. The next morning we swapped in our cam. The B3 cam is 10 degrees smaller in duration on the intake and exh as the cam GM speced out.
The 3rd day we got the engine fired back up after checking pushrod length and piston to valve clearance. We had MORE than enough. I told all the guys i wanted to pick up 100 with our cam. They all laughed and looked at me like i was INSANE. Considering they fight for 3hp in their engines. First pull resulted 986hp and 815tq I was deff happy once i saw that with no tuning. We started to get AFR dialed in and power started picking up. Once we hit 1000 the shop went crazy. They said it has been at least 15 years since anything made 1000hp on a dyno there. It wouldn't surprise me since they only do nascar stuff which makes about 850. I told him i would have been happy with 1020 and 850 tq. The engine was responding very well. After we made 1000 it then made 1014 then 1015. We made another pull and had to back out early but it still made 1031hp and 855tq popped up on the screen. Everyone couldn't believe it. We saw fuel pressure drop so we backed out of it. We then figured out that one of the fuel pumps had died. I feel we could have made 1050 is we had a few more pulls to play with it and could add some timing. The GM cam didn't like anymore than 17 degrees with the meth and we have ran as much as 24 degrees with our cam on an VERY similar set up.
The green line is the GM Cam. The red and black are the 1014 and 1015hp pulls and the blue is the 1031 pull.

I was down there last year, they sure have a nice little shop down there. Thats really cool for you guys to go there, and then impress the **** out of them.
It`s hard to believe the size of the place and the money thats behind everything. That area is so cool, everything is racing!!!
I will be headed back down in May for the All Star race; I wish I had tickets for the 4 Wide-Nationals in a few weeks .
Nice job Fran, and thats a cool story/trip to have under your belt.
