Hi guys ,

i have an ls1 motor and i thinking about putting MAGNACHARGER but i want the best psi so that i decided to stroke my engine to 383 , after searching and researching about 383 stroker assemblies i saw 383 engine kit like this one ( http://www.summitracing.com/search/D...T/?keyword=383 ) but with dish pistons , then i got idea why not putting this kit and save my money !!!!! but i wondering which one is better and give me more psi without hurt my engine the engine kit or stroker kit ? how many psi can i get in both ? how many hp can i get in range of both ?

Note: am a daily drive , i have bolts on and H/C before.

Well they are the same as far as I know. Also the link doesn't work. A 383 Stroker Kit or Engine kit are the same except for the components that come in them. Built for boost I would do a 383 Rotating Assemble from Texas Speed, Callies Crank and Rods with Diamond Pistons, get it balanced also.

Nice but how many psi can i force if i have stroker assemble ? And how many hp ? Because i want it for street racing ! Ofcourse with safe side !?

Which Maggie? If the 112 I bet it'd be too small

In fact , am lookin for supercharger (procharger or magnacharger) but i prefer magna ! Any way am lookin for maximum hp i will get from 383 assemble not important magna charger exactly ! I want to know how many psi can i forced the 383 then i will look for the best charger can give me this psi ?

psi depends on the internals of the motor among other things, what is your hp goal, as i have heard before psi is a worthless gauge of power due to the variences in air output of different setups

ok if i put 383 stroker with dish piston because i want extra psi can 383 assemble afford ! what ps1 can i get ?? hp ? and waht is the best dish iston can i put on 383 stroker ?? thats all what i want !!

Slap a f1a on it an dont look back

al3flangy

exactly what i want is :

what the best piston can give me maximum boost that 383 can afford it ?

what is the maximum boost can i get if i but good procharger(intercoolerd) with good piston?

which procharger can give me the maximum boost can 383 afford it ?


!! of course in safe side and daily drive

With a set of aftermarket AFR,Trickflow or RHS heads, which have a thicker deck, you can safely run 19 to 20 psi of boost without lifting the heads. With a stock style head I wouldn't shoot for more than 16 psi of boost. So you need to decide how much boost you're going to want to run, and what cylinder heads you're going to use, and what compression ratio you're going to run, before deciding on the pistons. Bob

If you just want huge boost numbers to brag about... drop in some 7.1:1 pistons and run 40 lbs all day.......

But, that is a recipe for a very poorly performing street engine.

That won't work and will only confuse the op. I suggest shooting for a compression ratio in the 9.5/1 range, and the pistons can't be ordered until the cylinder heads are decided on, and it is verified that the block only needs to go .005 over. Bob

al3flangy

so its mean that stroker 383 can afford 20 psi but depending on my heads then my piston (compression ratio) ?

Bob@BruteSpeed

iTrader: (16)

Correct. With the proper fuel system and a good chassis dyno tune 20 psi can be had. Bob

ok what about procharger and his problems i heard somebody say procharger have belt slip problem if its right what can i do to solve this problem ??

Order the optional ASter bracket and the front mount intercooler. The Aster bracket takes care of any belt slippage. Bob

You're a dumbass. If you aren't contributing anything valid or helpful you're simply padding your post count. This is supposed to be an informative source, and you just sent that idea through a wood chipper

LS1 stock crank, scat rods 10.3 on the pistons ls6 heads little porting on the exhaust 224/230 581/590 comp cam with 9 psi 90mm tb, on the maggie will get you in the 530/550whp and 550 torque at 2500 rpms.
Maggies have a tough time with heat after 10 psi. You don't need to build the 383 with a maggie. Your torque is there the second you hit it.
If the most HP is what your after the A&A style of blower is the way to go. two cars with Maggies on both and would not change for anything but there street cars. Not track cars. Figure out that first and which one you want then worry about strokers and psi.

If you want a maggie stay above 10 :1. Dont bother running any less with the mp112. Depending on your motor, a stock block at 10#'s will get you close to 500 with headers. Run a 8 rib, mp112, with a 2.8 pulley, meth kit and 1 7/8 headers with a good true dual setup and your going to haul ***. I would run the stock block you already have. At the very least maybe a nw set of pistons off the shelf mahles or something like a -2 cc dish. If you dont need much block work in the cylinders you could just run the .005 pistons and new rings. The mp112 will not push much more then 10-12 lbs. And thats pushing it. But youll see over 400 ft lbs of torque at the wheels before 3000 rpms.
