No, that one's in the Reef Blue car, "Grover", in the background. It has a Super Victor 363. Street manners are worse, but easy to work on and very clean looking.
The dark blue car, Father Time, is a 331, but both are pretty close to each other in build, aside from the intakes. Both have
- Dart Iron Eagle 8.2" decks
- AFR205 heads
- 220-230 duration HR street cams
- 76-80mm turbos
- Accufab 90mm TBs
- similar fuel systems with weldon pumps and 120 lbs fuel injectors
- T56s
- Big Stuff 3 computers
One key difference is static compression. When designing the Father Time build, I'd come across the idea that lower compression and higher boost allowed for more power before detonation, and it made sense to me. I've run as high as 18 psi with it on street gas. It made 761 rwhp at 15 psi. Thats wasn't too shabby back in 2008. I wanted it to make 1k rwhp, but the only time I really tried to push it, there was so much back pressure that it couldn't keep the wastegate closed. It made 881 rwhp with Torco on pump gas at, I think 20-21 psi. I think it could have made it to 1k, but we'll never know as I recently swapped to Forced Induction's 1500 hp advertised rating GT42-80. Goal is 1.1k on race gas to the tire now. Not sure the fuel system is up to task, but we'll see.
Anyways, if the box upper will fit in the engine bay, it's the better choice for most builds. I'm a little rusty on all of the details, but I seem to remember the long runner R struggling to compete with other long runners down low, and at mid range and up, it's dominated by the Box.
I pulled some stuff out of Richard Holdener's book when I was in Afghanistan researching what to do next and the article convinced me to upgrade from my 75mm TB to the current 90. In a combo not too different from the basics in mine, the Box-R with a 90mm TB picked up almost 40 rwhp over the long runner R. The 90mm TB picked up 14 rwhp IIRC. I know different combos will be different, but it's hard to argue with differences that big.
