Hey guys it's been a while since I've been on here haven't been working on the truck much have been pretty busy traveling for work the last 2 years, I see I've missed a lot of cool ****!!! Nice going on everyone's builds! I remeber when we were all just starting to figure out how nitrous worked lol

Anyways getting back to my truck build and I'm going to change a couple things because we all need MORE POWER!!!

With that being said I was wondering if you guys could tell me what possible weak links you see with my setup my truck is pretty cave man now but it's not my DD anymore so I can fully devote some quality build time now. With that being said here is the truck as it sits currently and the build thread.

Engine:
5.3L
Thunder racing 220 cam
Chromeoly push rods
Patriot dual valve Springs
Titanium retainers
Edelbrock Super Vic intake manifold
60 lb bosch injectors
90mm TB
Stock heads and bottom end

Drive train:
4l80e stage 5
Circle D 3000 stall
3.73 gears (stock)
2 piece drive Shaft (stock)
Tru cool 40k

Turbo
Rear mount Master power 70mm
Tial wastegate 9 psi spring
Tial BOV
Alky Control methanol injection single nozzle

The truck seems slightly sluggish some times, it ran a 14.2 at 98 on 9lbs it weights 5280 with me in it (155lbs) and full of fuel I was expecting a little more seems mucho slow to me.

My Current goal is to get this truck to the low 12s maybe even 11.99

First thing I'm doing is going front mount with Tricks manifold and crossover I currently have a BW 75mm fresh in the box never used (don't know all the specs it's in my shop up north will get later) is this the best option or what would be a good turbo for my setup

So gentleman what are your thoughts????

intake /in my opinion. they look good under hood . but rob low end torque

Intake and the stock rear diff if it's still a G80. Not that it will make you slower but the G80 isn't very strong.

A truck manifold would make more torque in my eyes.

Find a TBSS cathedral port manifold and your 90mm will work and they make great power for a factory intake. What AFR and timing are you running at 9psi? Those times seem off, your mph isn't high so it's not that it is just struggling off the bottom. Is the tune really conservative?

Not sure what the timing is but at 9lbs I belive the Afr is around 12.3

Is that with the alky being sprayed? Add some fuel either way.

With running a 60/30 mix turned half way up on the selector it runs around 11.2 I belive

Tune, intake, gears unless you're running a really short tire. Truck just isn't making any power for your setup and you should be leaving on full boost if you're not. Iirc my 07 weighed 5050 with me.
