Need help picking a turbo plz - 04/30/14 08:57 PM
Ok i want to put a pair of Turbos on a 318, about 7.25:1 actual comp. trying to figure out the right AR and Trim so it works right or better lol. I'd like to end up around 500hp but i'll take what i can get. Thanks

Re: Need help picking a turbo plz - 04/30/14 09:41 PM
I have a twin 66mm gt35s turbo 318. this is what I run for turbos
compressor side a/r .70 trim 55 66mm inducer
turbine side a/r .82 trim .82 64mm inducer thay work great there good for 550hp each

Re: Need help picking a turbo plz - 04/30/14 10:35 PM
500hp total?!
I'm not sure if you can put two turbo's on a V8 and only make 500hp... lol
All kidding aside...I'd try two Mitsubishi 14B turbo's off the DSM stuff (Eclipse/Talon). Small enough that they'll spool, and they will support 500hp on a 318 with no issue. They are internally wastegated too, so it'll save you that expense.
Also why 7.25:1 compression? Are you trying to run non-intercooled 87 octane?
The low compression will hurt the spool up time as much/worse then the A/R will.
Unless you have a good reason to go twins, I would just put a cheap single GT45 turbo on it ($300). It will support 500hp without issue.

Stock lower end so i figured i'd be nice to it, 500 will be plenty for a 2900 pound street car...for now. I have a 360 block waiting but money is tight and i figured i'd get the bugs worked out first, new to boost don't need to scatter a good block. I want the twins for the cool factor nothing else, i'm doing a twin carb draw through. I already have 2 complete turbo units from a couple old Buicks to get the carb manifolds(liquid cooled). Blow through is not an option please don't beat that Horse

I thought the turbine side needed a smaller AR and Trim, how fast do they spool? I'm afraid the already low compression i have might be an issue, just askin thanks!

Not to burst you bubble but that car will weight at least 3300 w/o driver.

Re: Need help picking a turbo plz - 05/01/14 01:32 PM
Yeah, I think it's a bit heavier than 2,900 pounds. Our '70 Dart weighs 3,400 without driver.
Turbo project sounds interesting, keep us posted on it.

Re: Need help picking a turbo plz - 05/01/14 01:57 PM
What year 318? It probably has a steel crank. I'm not sure the bottom end is the limit here.
Draw through? I'll just say compressing air is a lot easier than air/fuel. Plus increased charge cooling with blow through.
GT45. will make plenty of power, and be straight forward and easier to tune.
Not 2900. maybe if you have a 7.25 rear and no interior. My dart was fairly light for a street car. ~3200 with full bench interior, iron headed small block, alum rad, alum MC, alum wheels, manual steering, glass hood.

The low compression will hurt the spool up time as much/worse then the A/R will.
On my turbo car, everytime I dropped compression the spool got better and it made more power everywhere.
I am in the process of dropping from 8.5 to 7.8.
It seems counterintuitive but on a boosted car the lower the CR the better.

I'll let you weigh it when you're done... but you're right 500hp is safe on the stock lower end as long as you’re careful with the tuneup (boost/timing/fuel).

Nothing wrong with the 318. It will require just a little bit more RPM then the 360, but it will make plenty of power. Lots of 302/331 mustangs out there making 1000+ hp. The only benefit of the 360 block is the bigger main if you're going to run a cast crank. And it will spool slightly better because of the bigger engine size. But nothing to worry about.

Nothing wrong with that. Just know you're in for more fab, more money, etc... You can easily meet your goals with one small turbo and less work, but I get it. My motor would be a lot faster in an A-body too… different is ok.

I am more than happy to beat this dead horse to save you despite yourself... lol
Think about this REAL hard for a second. If you're already defending this because EVERYBODY is telling you not to do it...you should have a DAMN good reason not to go blowthru. And "cool factor" is certainly not a good enough reason. Drivability, power, difficulty to tune, and most importantly the ability to get help from people, all outweigh whatever reason you think you should do drawthrough!!!!!
If this is your first turbo project, and you’re still asking simple questions about A/R and sizing, you’re probably not in a position to try something extremely difficult, and outside the mainstream.
Do yourself a favor and build it blow through. The project will be complicated enough as it is, and you will have a steep learning curve just to make a conventional turbo deal work. There is no good reason that you would want to make this 10x harder on yourself. You’ll end up frustrated with a pile of broken parts.
Isn’t a twin turbo 318” cool enough? LOL

I wonder how much of that perceived better spool was because the engine was already working so much harder just to run that it was already on the threshold of building boost?
Was that on a V8 engine?

Draw through really??? Don't know why anyone would make a conscious decision to pursue something that is sure to be extremely frustrating and time consuming. It's challenging enough to do with blow through! Might want to switch to points ignition, bias ply tires, and 4 corner manual mechanical brakes to keep moving forward with the latest and greatest cutting edge technology!

I think he has a pair of OLD manifolds and carbs from
the early set up... there is a reason they dropped
that set up... I worked on a buddies old V6 with that
draw through set up... what a PITA to get it right

Re: Need help picking a turbo plz - 05/01/14 05:37 PM
If i go blow through i have to change the regulator,pump,add a return line to the cell, pay to have the carb modded.
From what i've read blow through has it's fair share of problems on the street with it's tuning.
So really, why shouldn't i do draw through?
I have a friend that ran a draw through setup on a 350 nova back in the day and it was very streetableand fun to drive.
I was a metal fabricator, i am now a carpenter of 26 years and my Dad was a mopar mechanic for 36 years i know a little bit about building things from nothing.
Just needed some help picking turbo sizes.
You guy's need to broaden your horizons

You can't say, "I am ok with the cost of two turbos, two carbs, and two intakes, and I am a 26 year fabricator." And then in the same breath that adding a new pump, and running one return line as being reasons against going to the better carb system.

Compared to EFI maybe. But other then that, not at all. I have made one high speed air bleed change, and jetting changes... that's IT. Also, if you think putting two separate carbs WAY upstream, in a home made intake manifold is going to work better at idle/cruise then setting a carb on a regular intake... you're in for a surprise.
Quote:

If you are honestly asking that question, you have clearly not looked into the reasons yourself.
-Cold starts can be awful... and considering you are in Michigan it's a real concern around here?
-Draw through severely limits your turbo choices because you'll need a carbon seal type to keep it from sucking oil at anything but WOT.
-There are VERY few people to help you when this doesn't work or has issues (since the rest of the world has abandoned this technology decades ago).
-Can't use an intercooler.
-No BOV system to protect the turbo/carb from backfire.
Etc...

I don't think anyone questioned your fabrication skills. But since you've NEVER built or tuned a turbo mopar, you'd think you would be a little more open minded to those that HAVE done it.

Pretty gutsy comment to make to a bunch of people with a LOT more experience then you who are trying to help.
So you never answered the question. Aside from being stubborn...why WOULD you want to do a draw through.

Well the internet is probably the wrong place to be looking then. I suggest you try books... preferably dusty ones with black and white pictures. Only those will have the encouragement that you're looking for doing the right thing with cutting edge technology.
Good luck.

That a 68 GT? No way it's 2900 unless you've got lots of fiberglass and gutted. Close to 3300 if it hasn't been thoroughly lightened!

Thanks, i havn't weighed it and don't care all i know is the piece of crap in it now ain't no fun anymore. Even with all the go fast parts it probably only makes 225 at the crank, not acceptable. And when i go the 360 route it will be costly cause it's getting a stroker kit so i'm just looking to have some fun at my expense before it get's expensive lol. Just planning on picking up some cheap turbos and learning a few things, my reading retention sucks so i learn hands on.

Good luck on your project!
Although, after playing with turbo stuff for awhile - your pain threshold must be pretty high - or will need to be to see it to the end and call it tuned to your expectations. There's a reason people don't do things that way anymore, which I'm betting you will find out for yourself. Just remember - everybody TRIED to help! LOL
But honestly, good luck with your project and take lots of pics!

Can anybody plot the range and trajectory of a carburetor after it goes thru the hood under a 10 PSI of boost backfire?
20 PSI?
What would the effect be steel vs 'glass hood, right vs left carb?
Seriously, quickd100 has had some success blowing up a 318 with a draw thru running a single Thermoquad and making the numbers you are looking for and then some.

But fine i get it and i like my bulg hood.

Seems like cost is a huge factor. Don't know how low buck you could complete a hack job turbo setup because it's not how I operate, but I can tell you if you choose a cast 4.000 crank from Ohio, Scat I beams, and KB hyper pistons that stroker project for the 360 block wouldn't be too pricey granted you've got heads that could support it. By the mention of go fast parts I'm guessing you've got decent cylinder heads, and if you do why did you put them on a short block so low in compression?

Seriously, quickd100 has had some success blowing up a 318 with a draw thru running a single Thermoquad and making the numbers you are looking for and then some.

I found if you use the Mopar factory accelerator cable will keep it from going very far.

Thats cheating you got one of them fancy intakes thats made to blow apart.
But fine i get it and i like my bulg hood.
Any suggestions on a decent affordable pump, regulator and any any other stuff i'll need to go Blowthrough? You guys nag more than my wife.
Seems like cost is a huge factor. Don't know how low buck you could complete a hack job turbo setup because it's not how I operate, but I can tell you if you choose a cast 4.000 crank from Ohio, Scat I beams, and KB hyper pistons that stroker project for the 360 block wouldn't be too pricey granted you've got heads that could support it. By the mention of go fast parts I'm guessing you've got decent cylinder heads, and if you do why did you put them on a short block so low in compression?
Bought it that way. I was told it had 10.1:1 ross pistons in it, wrong. Pistons are .092 in the hole with 72cc chambers in the heads and a .056 thick head gasket 4.060 bore. I've got a whopping .017 piston to valve clearance on the intakes, the heads are 360 j's with 2.02 intake and stock exhaust. They never even swapped out the exhaust seats, they were hammered and the original reason it came apart. The .528 solid cam is the only reason it lives, i shift at 6800 and i've beat the crap outta it with no issues yet....

I forgot about the OEM carb tether system.
Does that pass NHRA tech or do you require an additional "approved" one?

A very good choice... with that set up you can/will
have help from people that have or are running the same
style package... plus you get a larger choice of turbos

Its always best to match the supply line or go larger
so you dont make too much pressure in the return...
just get a boost reference regulator... I have a Mallory
thats boost referenced on my NA set up already for

Ok on the regulator, now i was looking at 140 gph pumps but what pressure will it need to be? Or Can i hook 2 holley blue's together to get 28 psi

It should in the 2800#-2900# range... no you cant
parallel 2 holleys to get 28#...when you do that you
gain flow.. not pressure... since your going to run
a carb you need flow but maintain the 7-71/2 psi..
if you go injected you need in the 50# range

Re: Need help picking a turbo plz - 05/03/14 12:32 AM
for the pump u need 6 psi at idle and 1 psi for each pound of boost so 10 pounds of boost is a min 16 psi fuel pressure and a boost reference fuel pressure regulator with return min - 8an line

On my turbo car, everytime I dropped compression the spool got better and it made more power everywhere.
I am in the process of dropping from 8.5 to 7.8.
It seems counterintuitive but on a boosted car the lower the CR the better.
I wonder how much of that perceived better spool was because the engine was already working so much harder just to run that it was already on the threshold of building boost?
Was that on a V8 engine?
I'd like to dig into this further when I have more time but I will add this:
I have had my own dynos for almost 10 years so I test every change I make to my car. The power curve started higher and earlier with nothing more than an comp change, it was 400 rpm earlier and 28 rwhp or so higher , same turbo, same tune, same boost controller.
The car was a rotary, but its still a 4 stroke motor. The comp change makes the total volume of the cylinder or chamber larger.
Dave Vizard wrote a lot about this in his books, and was the deciding factor for me to take the motor apart to go down to 8.5:1 from 9:1. I put his theories to the test and its proven itself. The interesting thing is the 8.5:1 rotors are actually heavier than the the 9:1 rotors, and the engine still made more power with the 8.5's.
When he says on the cover, speed secrets for any engine , he isn't kidding.

I'm an idiot, the T i have that splits the carb line has the gauge in it, for some reason i thought the gauge screwed into the regulator.....

It could be marginal... as you add pressure you reduce

To be honest you dont need that pressure but you want

pressure so you need a good return(big)

if your looking for 500 hp u need a 83 gph gallons per hour to make 500 hp. the expert blow thr carb guys say fuel pressure 7 psi at idle; say 10 psi boost, 6 psi for line loses for bends turns ext in your fuel line system to carb. so for 10 psi of boost you should be able to have 23 psi fuel pressure and 83 gph.. I donot know on your 318 but I think u whould need about 10 pounds of boost to make 500 hp

I've been using the 255 walbro and mallory 4309 reg. for years, -8 feed and return with no pressure creep problems. You are going to want a gauge to read while driving to verify the pressure is increasing with boost.

Nobody is born "all knowing." People learn by doing - and either learn from their own mistakes or mistakes made by others. It's FAR easier to learn from other's mistakes. It doesn't cost time or money. Unfortunately this previously learned knowledge from learning from other's mistakes does come with a price. Nobody likes criticism, constructive or otherwise. The price is swallowing your pride enough to understand what and why they are saying what they say to help you.
If you don't want to "pay" that price - you are ALWAYS free to learn from your own mistakes like most of us have before the internet became such a good tool for disseminating information. We all learned the hard way. We are certainly willing to help people learn the easier way - but we may not all be the best "teachers." We put things in terms that we understand and I guess we don't sugarcoat it as much as some would like. We're sorry we're so gruff and to the point. After all, we're gear heads, not teachers. We're here to try and help - even IF it doesn't seem like it to you right now.
You're headed in the right direction. Grow thicker skin and soak up the knowledge that's trying to be passed to you…. even if it's not worded as nicely as you would like. The price really isn't that high.

I have not built myself a turbo car (yet), but I am helping a buddy with a 5.3/GT45 combo in a fox body, and I do this stuff every day for a living.
As far as the $350 pump...a Walbro 255 is $90, unfortunately all of the regulators are pricey...check forums for used parts...
