Default The quest for 850rwhp. Stay blown or go single turbo??

Well, im waiting on a quote from AES and for a 390. My goal is to make 850rwhp, on somewhat of a budget. Just a small break down for you guys. I want some opinions on this. I plan on ordering the motor in december, but that all depends on work. theres some rumors running around about lay offs, but rumors are like *** holes... so just a quick run down..

AES 390
Ported/Polished 317 heads
Custom Blower cam from AES
Head/main studs
LS7 lifters

Going to use off my motor..
BBK intake
Stock ported/polished throttle body
Covers, sensors, rockers...ect..
LS6 ported oil pump

Fuel..
Lonnies DP (or add another racetronix and wire myself)
80lb Injectors
-8an feed, -6return
Aeromotive FPR
BBK fuel rails
Snows Meth kit

cant decide to...
Keep my D1 w/ 3.4pulley
or...
pick up an F1A...
Aster bracket of course...or modify my stock J-bracket.

add the kurt urban steam vent.

How it look?

EDIT: Opinions on turbo setup. Would it be cheaper to sell my D1 setup and go with like a single 88mm turbo vs selling my D1 and spending anther $1000 to get the F1A... ?

I would go with the F1A. I have 370ci D1SC with the 3.4 pulley and the blower is maxed out. I put down 785 rwhp so far. I wish i would have just went with and f1, that is next on my list. Go with the Aster bracket, works great!

i wonder if having 20 more ci would make that big of a difference... id like to have some power under 3000rpm to...my car now is a screamer as soon as it hits 3000...under that its kind of doggy.. Im leaning toward the aster bracket, but i dont wanna have to wait 4-6months on one... What kind of torque did you put down?

Yup, 93+meth. Ya thats what i keep leaning on is the F1A, or even an F1C. just gotta find a good deal on one when the time comes..priorities would be.. Engine>blower>fuel

My torque is 708 @ 5500.
There is no traction on the street until 3 gear at wot. The Aster bracket is worth the wait.

402+worked LS3 heads+my custom cam(232/244-118+2, for the wife and to drive like stock)=850rwhp/797rwtq. Did 825-850rwhp on 4 different dyno's. Blower used was a Novi 1500(T-trim), a lot smaller than a D1SC. Did it on a 6 rib belt and beat the crap out of it at the track and street. In full street trim, my best trap was 149mph with no skinnies, weight removed, etc the way I drove the car daily. 3600 pounds with 6 point rollbar, banging gears.

Chris is building all the asters brackets for the GP right now, and he is going to have two extra brackets when it is all said and done. Now would be a good time to buy one, as the wait won't be as long.

You're going to need an F-1A to see the kind of power you're looking to make. Bob

An F-1A on my 408 with AFR 225 heads and our blower cam made 18-20 psi with the 8 rib serpentine system with a 3.90 pulley at 6500 rpm. I'd check psi before and after the intercooler, something doesn't sound right. Bob

damn, i wont be ready to buy until im ready to sell my D1...i fiugred itd be easier to sell my D1 if i had the bracket with it...and vice versa.. i wont b ready to sell mine until about jan-feb. i wanna get the motor built/paid for before i tear mine out. just incase something happens financially, ill still have a car to drive....how long is the usual wait on one?

and i keep leaning toward the F1A...ill even take an F1C if i can find one. i can do something custom with the radiator if need be. Ill probably get rid of the A/C as well since i dont use it. i wonder if a single turbo set up would be cheaper? ill have to look into that option as well.

I was thinking the same damn thing. missing about 175-200rwhp. it may have a restriction inside. its happened before. as far as going turbo. J$..... you will be able to hit the number of course, however its at the cost of chunking everything you already have and starting over which to me does not sound cheaper. You seem to like quality man. You'd possibly needed a special k member. i mean all you need right now is the new blower and bracket to have the setup you want. vs needing a ton of ****. ill prob turbo the next TA i get. 91mm 408 and take my time vs going all out each month.

I'M making the switch for this reason. I did the math and the cost of getting a bigger blower (brand new) was not worth it. What's a new f1a cost 3-3400$ ?? I got a brand new pt7675 which can do 850-900 and brand-new complete turbo kit for 3200 bucks. Not including WG or bov. Also add few bucks for fasteners fiulds and other stuff. Was a no brainer or me. Yes I lost my
Ac!! Big deal don't brother me. DoNt get me wrong I loved my procharger and def will buy another one day but.. I want to try something different and get to my goals easier! This is just my .02 cents

im not really starting over. id need a hot side, turbo, bov/wg, boost controller...i already have the cold side setup, just modify the tube going to the intercooler for placement of the turbo. i could prolly get $3500 for all my stuff.even if i had to throw in my cold side, the IC setup is only $250... the motor would be new and would be easy to cut the oil pan for the drain...i dunno. on the other hand, the procharger sounds bad ***.... and is a more simple setup.. i have a few months to figure it out i guess...
