I was wondering if I put a intercooler on my car would it be good or bad for the engine? Another words will the cooler intercooled air put more stress on my engine and result in advanced engine wear? I know that if I get a intercooler it will lower my boost levels particularly at higher speeds so I was thinking if the intercooler lowered the boost to say 5 PSI or so I could then put a 3.25 dia. pulley on and bring the boost back up to 6.5 or so. If I did this would my engine be getting pushed harder or the same? I know I would get a lot more HP out of this set up but I don't want to beat on the car any more then I am now. Thanks for your thoughts!

3.25 and your expecting 6.5? you know what i'd do.. get some better rims 1st then swap the pullie u can run i'd say 8.5-9.5psi on the internals you have with out intercooler or nos cooling.. from there.. get a nice intercooler setup.. and raise boost to about a 2.87 pullie and then thats about 12psi which should be more than enough.. but i'd say upgrade that tranny before going there

I don't plan on doing this until next spring probably. I just want to make sure I want to do it first. How much boost are you running Phil? And do you have a intercooler? I wish you would tell me all your mods but ayy. Ohh yeah you don't think 8.5 psi would be more damaging to my engine then what I have now? Thanks

Phil02E46

i know of a few running the 3.33 pullie with minimal mods and its not doing any harm to them.. the main goal u want is more fuel.. since the boost increases the air.. so might wanna upgrade to the 300z fuel system.. the one stillen gave u only upgrades half the ****.. you still need the injectors and that stuff.. intercooler is in the works.. at the time im cooling my intake temp a diff way.. i just can't see putting two 90deg turns in my intake piping as being good.. but who knows..

Please elaborate, Phillip. How are you cooling your car down and how many lbs. of boost are you running? Also, what is the fastest E.T. your car has witnessed?

Phil02E46

what was the question again?? im all about stock, stock is good, stock is grand, stock is what i have

OK, Phillip... your secret is safe with me, Batman!

I re read your post and it kind of sounds like I should put 300XZ fuel injectors on now. Is this true? Would I gain more HP with them? How much are the 300ZX injectors? Thanks a lot Phil.

Phil02E46

with the stock boost i don't think its needed.. but when you start running higherboost you need more fuel so as you don't run lean and blow up your engine check around at parts.com and other places.. i believe they're 3something size.. hehe or you can get some custom setup depending on what you want.. but with your 6psi stock i wouldn't see the need

You car will run like **** if you just put only the Z injectors on.

Maximamike

Heh.. I know part of the story

Phil02E46

yeah.. tony's right.. no way did i mean just the injectors but i don't think he really needs to go taht way for a while..

mikey.. what do you know

A good intercooler will lower your IAT(intake air temps) which will allow you to get more air into the cylinder thus will the addition of proper fuel equates to more power.

A good efficient intercooler will loose very little boost. I lost approximatley 1 to 1.5 lbs. of boost with my intercooler.

I was running about 8 to 8.5lbs. of boost with the 3.48 pulley without my intercooler. No extra fuel is needed with that pulley as I even was able to lean the A/F out with the Fields fuel controller on a dyno/air fuel meter for 10 extra hp.

If your interested in my 3.48 pulley let me know.

I'm now running the 3.25 pulley with an FMIC(front mount intercooler) @ 9.5 to 10lbs. of boost.

I'm going to the track next week!!!

If I were you, I would strap the car onto a dyno first. Find out what kind of power you are making and at what A/F ratio. I believe the Stillen kit runs really rich out of the box. You might able to get a leaner FMU from Vortech. Squeeze more power out of what you have. ~25hp. It's all about tuning. If you start to play the game of throwing bunch of parts at the car, you will have a car with tons of money into it that runs slow.

Why do you think Loren's SC car puts out so much power with stock psi? He knows the importance of tuning. He makes more trip to the dyno than most people.

Phil02E46

now just imagine what a properly tuned and higher psi max could do

SteveChicagoSC

tuning is the name of the game. I did lean out my fuel curve with the fields fuel controller.

Loren is running the 3.33 pulley not the stock 3.66.

See...if Steve have to lean out his fuel mixture, it means you have plenty of fuel. Until the point where you OEM injectors locks, you are just wasting money on the Z injectors.

I know that I still got "it". Hehehehehe..

man my car is still slow. i put in 38psi at the wheels and still pull 15's crap..

Ive been searching about S/C issues and came across this.

I think its a great thread.

Wow, I am getting flash backs over here from when I was 20 .

I guess it's a good time to update! I never got a intercooler and the SC has found a new home.

max'n out

I din't realize intercoolers decrease boost. How come? Why would cooling down the air decrease the boost of that air? Shoun't it go through just as fast? I was thinking of getting one 2. Thinking of a nice intercooler with the 3.33 pulley with the stock fuel system (stillen kit and nissan). What do you guys think. And what intercoolers would you suggest.

SithMax

How much does a basic dyno run cost? How much does a dyno run and tuning cost? A little help?

SithMax

Why? Why, Basic Chemistry my friend! *break into song now* As the temperature of a system decreases so does it's pressure. Cold air is more dense, like Fog condensing on a cool Fall night as opposed to sweltering humid summer nights. SO if a specific volume of air at a high temperature then has it's temperature lowered, it will take up less "space," but being a gas conforming to the space that surrounds it, that less space equates to less pressure. *begin spoken word break in singing* Think of trying to fit three crack addicts in your trunk. It's hard! They're all bouncing around getting rowdy. Now take four stoners. They barely move at all and will comply with anything you say so long as you give them that bag of chips. You can practically pour there blazed butts in the trunk. THAT'S the intercooler difference. *end spoken word break and now more singing* You lose pressure, but gain air. So force more air and keep your pressure with even more air, providing for some real increases in power, so long as your air/fuel mixture is right!!! *end song* And now you know why you lose boost pressure by adding an intercooler.
