I got the car on the dyno, the tune isnt completely done but at 14 lbs it made 738 rwhp 756rwtq. When im done i would like to be up to at least 16 lbs so theres quite a bit more power left on the table.

Setup looks awesome man great job! A few questions, what size dp and exhaust under the car? How much timing were you running on the 14psi pull? Does the crossover under trans hang low? What size intercooler? Meth? Sorry for all the questions but I recently for mine running and its set on 5 Psi, I'd like to start turning up the boost but Im running the msd 6010 with just a base timing curve in it with 35° timing. I know its alot but its safe with just 5 Psi. It runs like a raped ape on 5 Psi but Ian feeling the itch to get it on the dyno soon! Car looks great man nice job!

Its a new log set up I made, same design as before I just upped the size of the log on the passenger side from 2.5" to 3". I would highly recomend this turbo. I was concerned about the turbo being laggy but this turbo spools quick. From a dead dig at a stop light I can get on it and be spooled up by the time I get to the other side of the intrersection. I have a tbrake and a 2step but havent even used it yet, on the foot brake alone I can build up about 5 lbs in just seconds.

That's excellent to hear. I'm using the tc78 just this year, 3 1/2" dp.. trying to go 10's on pump gas. In a gmc Sonoma. Weighs 3600ish ... next year bigger turbo , hopefully 140 mph traps...

Theres a descent amount of room but I also notched the inner frame rail about a 1/2" for clearance when I had the engine out.
