YACT finished intercooling my minivan today :)

Pics
If you have seen the old shots the ones starting with 1115 are what I did today.

HEHE this thing is fun. It is still only running 10psi becuase I ran out of light and forgot to bring a wrench to adjust the grainger with on the test run. I'll bump it up to 13-14psi tomorrow. The talon BOV is a hell of a lot louder than I though it would be. Eventually it will probably become annoying but for now I love being able to scare small children . I can't say how much power it added because I have been driving my mustang for the last 3 weeks but torque steer is worse.

Next up larger injectors and 17psi .

Cool!

 

[Quixfire]

Very nice job!

 

[NutBucket]

Got a shot of the intercooler mounted.

EDIT: Just checked out the old pictures

 

[0roo0roo]

lol thats awesome. ultimate sleeper

 

[CFster]

Why.

 

[Slickone]

Careful. That engine's known to blow head gaskets, as you may know. You're gonna replace those long rubber sections with metal aren't you? What kind of pressure drop did you get?
I was thinking of building an IC system for my car, but it's just too much work and I don't have enough time. And of course if not done correctly and it's too inefficient, you gotta turn the boost up even more to compensate, so more lag. I might buy a mfg'd system ($800-$1300).

 

[thedarkwolf]

Yeah I know it may blow a head gasket but its no big deal to replace them on these. They run 9psi from the factory unintercooled so I am not pushing it much rightnow anyway. Most of the rubber sections are intercooler hoses off probes or talons so they should hold up fine. The 90 degree upper bend is a radiator hose but it should still be fine. Lots of people use radiator hoses and run way more boost than I will and most radiators run 12-16psi anyway. The only part I am really worried about is the reducer on the throttle body since its just something I picked up in the plumbers stection of Lowes. Eventually I will have to replace that with something better. This is by no means the best intercooler setup there is but I have maybe $70 in it and thats including 2 talon BOVs, bought one for a back up or to sale if I don't need it.

The airbox is just rigged in there till I can get a K&N cone filter in there.

Forgot to ask what kind of car you have? There aren't to many mfg'd systems for caravans .

 

[Slickone]

Recognized that reducer. They're pretty thick though. Most people don't use them because of it's right angles, and they like the colored ones. I think vibrantperformance.com or driverfx.com has reducers for $6. 90 degree bends really cut down effeciency. Can you get metal head gaskets for those?
Can you give me more info on the extra BOV you have?

 

[thedarkwolf]

You can get metal headgaskets for them but I don't think very many people use them. Alot of the turbo dodge guys use the headgasket as the weak point so that if something blows it will be the cheap headgasket and not the pistons. Doesn't always work though .

Pics of both BOVs
Both of them are metal first gens but the one on the left still has its plastic cover on it and is also the one I am using. They are suppost to hold to around 17psi and if you crush them will hold even more. Not sure what I am going to do with it yet. I'll probably end up trading it for some other part over on turbododge.com.

WOW!! A sleeper family van. Hope it all works out well.
Please, a follow-up when it's fully sorted out.

A short story if I may. I met an engineer that developed turbos for BMW M/Cs. Turbo lag is dangerous on a m/c when turning. In order to cut lag by a significant amount this is what he did.

Between the intercooler and throttle body he put in a very lightly sprung door, sprung like a mass flow sensor. This door would open pulling air in through a small K&N. As the turbo boost came on the door would close. This made a real difference off the line and when coming back on throttle after a decelerating down shift.

At idle there is no boost and the engine has to pull air through the system. With the door deal it did not.....Hope that made some sense. Just a rambling mechanic.........:sun:

I needed something to replace my 93 nissan truck's hauling abililty, something fwd for winter, and something that seats more than 2 people comfortably. This can do all of those and its turbo charged . Besides with this I can drive backwards going the wrong way on a one way street dragging a dead hooker and cops won't even look twice at it .

I have my mustang when I want attention.

Isn't turbocharging something that you want to have good traction in the winter counterproductive? I mean, it's not AWD like a Subaru.

Well it doesn't help. When it snows I just pop my manual boost controller out and hook the wastegate up directly to the manifold presure and I only get 5psi and it spools real slow so its not bad. I need to setup a solenoid so I can just flip a switch and choose between low and high boost but I am lazy. I did install a phantom grip style LSD this summer when I rebuilt the trans so that should help some too.

 

[EyeMWing]

Ah, my comrade in arms. *non-gay Italian-style man-to-man hug*

These insignificant ATOTers will never fully comprehend the power of the turbovan. I just replaced the head gasket on mine yesterday (It got screwed in the radiator incident), and it's back to running like new. I still need to intercool it.

 

[thedarkwolf]

Nobody does and thats what makes them so much fun. If the 1/8 strip is still open this week I'll have to see what she can do. Should get some pretty cool reactions no matter what it runs it will be faster than people expect .

Did you end up getting a new radiator?

 

I don't hand out a lot of complements when it comes to vehicle mods, but that's a job well done on such a small budget.


Nice

 

[Slickone]

After looking around turbominivan.com...wow! How can they be that fast? The HP can't be that high and they have to be heavy. I think the dyno there said 200HP? And how much do those vans weigh stock? What about after modding? And they're beating lighter cars with more HP, and better traction? It doesn't add up.

TDW, don't sweat the headgasket problem, the TBI engines are known for them, but in turbo form a blown headgasket isn't all that common. Anyways - what kind of cooler is that, a saab cooler or something?

If I were you, I'd be saving for an NPR and a 89 TII turbo, then the small stuff like the SMEC and injectors... that's where the REAL fun will start or even go for The Powerstroke cooler! (I'm sure you're well aware of this monster of an IC)

I'll bump it up to 13-14psi tomorrow.

Are you still using the stock Mitsu turbo? Try not to go higher than 15psi for long if so - that $hitsubishi will crap out at higher boost levels. I have one on my project Shadow unfortunately I can't wait to either get an S60 or a TII depending on how much money I have by spring time

 

[thedarkwolf]

Yeah its still the shitsu but if it does crap out that just gives me an excuse to upgrade to a T3. Its a mazda 626 intercooler which or pretty much a probe intercooler with slightly different inlet/outlet. Its not all that great but it fits well and doesn't screw up my a/c which was important.

Slickone the ones running 12s make well over 200hp. They are probably more like 300ish hp. Mine is probably only making around 175hp as is and with 15psi around 200hp which isn't all that impressive but its probablyl making around 250ft-lbs of torque as is and 300ft-lbs at 15psi. Stock they make 150hp and 180ft-lbs. The heads are restrictive and with the little stock mitsu turbo its hard to make a lot of horsepower but they do make tons of torque. These vans don't weigh as much as you would think. I took mine to the dump last year and with the rear seats removed and a full tank of gas it wieghed around 3200lbs.

Haha!! Spoken like a true turbododger Pretty much my philosophy with my Mitsu'd Shadow...

 

[thedarkwolf]

Just tweaked it a little and am now up to 12psi by my gauge, think its off by a little bit. I might be able to squeeze a little more out of it if I keep playing with the grainger/manual boost controller but its hitting the 14.7psi cutout when I go higher than that. The roads are a little wet and my new found power is making it a little difficult to screw around with it. Now when I nail that gas at 15mph or lower and it hits 10+psi I just light up the driverside tire and thanks to the homemade shift kit I installed when I rebuilt the trans it gets pretty squirly shifting into 2nd too . Going to have to wait till the roads are dry to play with it much more.

Thats what we put in the 95 L in my sig was the PS intercooler.. it's a monster

Nice truck

I'd love to have one of those coolers in my van but to fit one and keep the a/c would be a lot of work. This is a minivan after all and I do use it as one sometimes so the a/c is still important .
