I was thinking of building a 408 Ls1 with ET 265 heads, 9.0:1 compression, 244/240 .685/.685 114+4 solid roller, vic jr intake, 850 demon blow through carb, msd ignition, jesel shaft mounts,l19 head studs, main studs, all clevite bearings, twin aeromotive a1000 pumps with rising rate regulator, pt 91.5mm turbo, 50mm hks wastegate, 50mm tial bov, th 400 with 4000 stall and 2 step, I want to run 18-21 pounds of boost, and this is going in a 2400lb trunk lid mustang.

How much power might it make?
What kind of track times am I looking at?

In a 2400lb fox? Doubt it.

It might be a little hard to hold with 3.73 gears and a 28 by 10.50 but I'll figure something out!

2400 lbs???? is this a tube chassis car? if not Good luck getting it that light especially if you want it to have ANY type of creature comforts... heres an example:

My car

89 notch stang
No heat
No Stereo
No A/c
No back seat
No spare tire
No Power steering
no power brakes
Roll up windows
No sound deadening just a thin layer of carpet
mild steel 8 point roll bar
5.3 with plastic ls1 intake
single turbo kit with t76
full manual th400 with 10" 3600 converter
15 gallon aluminum fuel cell
single a1000 pump with -8 pushlock hose which is quite light
Racing seats
5 point belts
pin on 5" extended glass cowl hood
No inner front bumper
drag lites 15x3.5 front with 165r radials 15x10 rear with 275 drag radials
tubular control arms
8.8 with moser 31 spline axles/C-clip elims Strange 31 spline spool
stock 4 cyl brakes front stock 8.8 drums rear
Aluminum drive shaft
No inner wheel wells
Basically bare bones just the neccesities

2900 without me - Granted I didnt have the full tubular front end in it yet or the front coil overs which will put it around 2800 but you get the point .... trying to get another
4-500 lbs off of that with 1 more fuel pump way more roll cage a bigger turbo a heavier intake plus carb etc without going to a bunch of fiberglass parts etc might be pretty damn tough.

My 4 cyl fox weighed 3020 with me in it bone stock. I hope after full suspension, brakes, wheels, ect it wont be any heavier then before.

maybe it would weigh the same , but 2400 lbs???? thats a bit of a stretch for a motor thats way heavier a turbo kit etc etc

Did you have a few 100lb bags of cement in the car? One of my buddies notches (with full interior) weighed 2900 with him in it and didn't do anything for weight reductions.

Nope the car was on a very accurate scale(was your friends?) with a 1/2 tank of fuel ... I know I can get at least another 100-150 lbs out without the car being "gutted" Ive actually went back to stock seats and will be adding a stereo and stil lexpec tthe car to weigh in around 2850 which is pretty damn light still.

It was a certified truck scale. He only took out the front and rear bumpers, had tubular suspension, fiber glass hood, and drag lites. Had jug in it too.

BAD *** CAR by the way! Just watched the video. How fast has it gone? How many pounds of boost?

Thanks for the props , The car has so far ran 11.0@134 mph on 12psi and pump gas with a VERY mild tune up and a brutal 1.9 60 foot at our 2200 ft elevation... the addition of a transbrake and two step will hopefully get it closer to the single digit mark. I also have to put in my tubular front end,more boost and work more on the tune and it should be close.

You used truck manifolds didnt you?

Sure did ... they worked awesome only clearance issue was with the sway bar mounts but most guys have these cars set up for drag racing anyway and ditch the front bar .
