572 twin turbo build? - 07/24/14 02:38 AM

hello ,

I`m picking up my first 572 cubic inch motor at the nats this year.

Its a used motor. I`m going to take it to my motor guy and go through it. the plan is to add some turbos to it. LOL

Is anyone running this type of set up?
if so what are your motor specs? compression ,cam , ect...

is it true that for every 15 psi of boost your compression go's up 1
point?

thanks,

Mike

Why turbo such a big motor? That makes no sense to me.

Based on your questions, and not to be mean, but you need to do a lot of research and get educated on turbo setups.

First and most importantly, what are your goals? Once we know that, we can suggest, cubic inch, heads, cam, compression, internal engine parts, turbo sizing, etc.

Kind of.

A twin turbo intercooled 572 C.I. pump gas wedge motor can make north of 2000 HP+

How much HP can your car handle

I hope your new used motor is in good shape, maybe needing a freshen only

How fast(actually) have you been in a car

Be careful, first and formost

Forget the turbos with that motor and 2900# Duster.

10.5 comp. and the MP 590 cam will get you your easy 9 sec. street ride.

Unless your goals have changed and you want 8,s with it now.

Like others have asked, how fast have you been. Id start with the 572 first and then decide whether or not you want to Bother with Turbos.

No reason to Twin Turbo a 572 with a 2900# car unless you want to run7,s or something.

thanks for the replies. LOL

I plan to have the motor freshened. I got a great deal on the motor thats why I am buying it. as for the turbos it was just a Idea. I have a line on two 88 mm turbos.

the duster should handle mid 8`s no problem.

If you are getting a good deal on the engine & turbo's then by all means build it.With the twin turbos I would run a tunnel ram,do it while you have the chance because you may never find another good deal to do it in the future.
You can start off running it mild & as you upgrade your car you can keep adding Boost to it.

PS if nothing else do it for the WOW factor!

Well I guess he got the information he was looking for...

Looking forward to seeing the progress on this!

Been running a turbo'd 572 for years in my street car. Don't need much boost to go fast and you don't wreck parts since your not running on the ragged edge.

What heads/compression etc does this 572 have?
I can give you some direction if your thinking of doing it. 7's aren't too hard to get at 3500lbs on pump gas.

Switching to bigger heads and twins now but you can do some amazing things on nothing special for parts.

Re: 572 twin turbo build? - 07/27/14 04:41 PM

thanks guys. I will keep you posted.

The heads are 572-13 and the compression 14-1

I`m thinking I`ll have to lower the compression
to 11-1 or 12-1.

What do you guys think?

your going to need a swimming pool shaped piston to get the right compression with those heads and that stroke

Much lower then that, for what your trying to do. More like 8.5 to 9.5 max.

On my Super-Charged engine(which makes over a 1,000 Streetable RWH) my CR is 10.7-1 and I'm almost positive on the Turbo engines they stay at 10.7-1 also.I would talk with what they now call Tuners that work on the Super-Charged & Turbo engines.The Turbo & Super-Charged engines have come a long way in the last few years.

Mid high 9's for comp if your sticking to a pump gas type engine and 50+cc dish, 9.7:1 here.

Made 1550RWHP on 17 LBS with edelbrock Victor 440's. Since you have bigger heads you could be 1500rwhp on 13-14 lbs on pump gas with A/W intercooler.

I can safely comment that turbo apps making 1,000 rwhp on pump 91-93 gas are not using 10.7:1 compression ratio unless they are adding meth or something like that.

Also, the OP, must decide what fuel he will want to run, to finalize compression, or be prepared to adjust things otherwise, like stated above.

thanks again for all the info. I`d like to run on pump gas (93)

Have you considered e-85? Blow thru or efi?

I can assure they are,while mine is Super-Charged with 10.7-1 CR with that being the stock CR on the all aluminum LS3 from the Factory I can Safely say that's what most of the Turbo engines are as well.And that is with a mild tune streetable tune up set up to run 93 that you can buy at most any place.A Turbo or Super-Charger does not know or care if its on a Mopar,chevy or ford engine what works on one works on the rest.
The Turbo & Super-Charged engines have made Big Progress in the last few years.That is all a lot of the whats now called Tuners do is install & tune Turbo & Super-Charged engines and they can advise and sell you everything needed or do it for you.

If you are going to the Turbo or Super-Charger on your engine,you can not go wrong by taking the time to find some of the Big Time Tuners in your area before you start the buying process.

PS Turbos & Super-Chargers are like NOS,if you do it right you make some unreal Horse-Power,but do it wrong and you will wish you had never done it.
