Default the twin Magnum T-70 408 build

Car started off as just a H/C/I/E car. Was pretty quick and put down 464/398<-?? can't remember the exact tq number. but it was fast but not as fast as i wanted to go. Needless to say, I made the big dive into the world of boost. Car went down under the knife on June 20th 2011.

The build now consists of:
LQ9 6.0
TSP 408 Stroker assembly
ARP studded 317 heads (untouched)
Victor JR. w/ Aaron's elbow
FIC 103lb @ 58psi high imp. injectors
Fast 92 TB
Griffin radiator w Zirgo 16" single pusher 3,000 cfm
Treadstone TRTT9 intercooler
Dual Walbro intank, external FPR, Edelbrock rails, converted evap as a return
Twin Magnum T-70's T4 81 A/R w/ Q trim exhaust from Modular Turbo (thanks Rob)
JGS 500 BOV (50mm)
twin Tial MVR 44mm gates
Eboost Street
truck and ls2 exhaust manifolds
built t-56
stage 4 Monster clutch
mail order tune from Allan Futral

I did all of the work myself for the exception of the internals and my buddy Shawn aka: SUPERMAN_00TA on tech. He helped me with the welding of the turbo kit that I made out of random bends and straights. I will try to keep the pics in order according to build progression, but there are so many i really don't care lol.

Pics coming soon

for the n/a set-up or the boosted set-up? I haven't gotten the new set-up dyno tuned because it's not even driveable yet. I got the mail order tune so i can get it running and finish last minute issues (notorious)

really upset that some of my pics i had on my old phone was lost after my phone fell in the toilet. I don't even have the pics of the turbos I should say, i have never done anything but some oil changes before this. I am not a experienced guy in mechanics. I searched and asked for advice from seasoned guys on this site.

Worst idea ever, unless you have a wideband, experience, and tuning software on hand, Im sure Allan's tuning is great but please save yourself and your motor by allowing someone to tune it on site.

For real.

I sure will. I haven't cranked it since that day because my wideband is showing 18.6-20.0 at idle and about 17-17.5 AFR at 1500 rpm. Kinda scared the crap out of me. My fuel pressure sending unit isn't working so I want to get that issue resolved first so I can rule out lack of fuel pressure as a culprit.

Yes I agree, it is still a pain man. can't wait to get these last few issues resolved so i can break the block in. twins vs f1 is definitely a good attraction. two 408's similar boost level, both t-56, good drivers, different power adders... going to blow up youtube
