Well, for the most part, this project is nearly complete. I will be plumbing the intercoolers this week. I have a Sureflo pump and I like to use a small a/c condensor as a heat exchanger (most are double pass). I have yet to tune the engine for high boost/high hp. I'd say it'* making about 300whp on ~10psi combined (5psi turbo, the remainder added by the */c). Running around in 3rd gear now, the turbo will spool up to 5psi as low as 2500rpm!!!! The dual BB and .96 a/r combine for a killer boost curve! I plan to try smaller */c pulleys, too. I am thinking a 3.4 pulley will really wake up the turbo and help it get to speed even quicker as I slowly raise the turbo boost pressure. Remember, my goal is 500whp on less than 24psi (I hear that'* when the stock h.g'* fail with ARP head studs).
I also need to "tune" the transmission. I ordered a chip adapter from Moates so I can realtime tune the tcm with my emulator and Tunercat RT software. Here are the latest pictures. Once I get the i/c system running, I'll have dyno numbers for you.
Turbo and charge-air pipe:
LS1 MAF (not being used, yet):
Good shot of 8-rib 3.8" pulley and wood intercooler.
Another angle on the 8-rib set-up, a prototype arrangement from SFPH Dial-Ur-Boost (DUB) Thanks, Terry!
Mess of wires for pcm/tcm, it'll be much cleaner once I get it all harnessed back together and build a box for them!
Larger trans cooler
Modified oil cap for breather duty, I want to run it into the air filter "lid" and will do so eventually.
Wastegate works flawlessly! Goes to 5psi and stays flat no matter the rpm!
K&N filter was a tight fit, had to cut away all the core support in front of it and still had to bend it a tad get it over the turbo flange!
BOV spring was too tight, no BO, but I found a lighter spring that starts to opn at about 22"hg, perfect for high rpm/high vacuum blow-off with no leakage at idle.
16x8" McLaren Turbo GP wheels have the perfect offset for the Bonne! It looks like a Nextel Cup car with it'* bulging fenders!
