Thats a great result, and not too uncommon either. But I highly doubt his quad-turbo setup will have the same results.

 

no but its gonna be fun for some bench racing. but either way why won 4 small ones work it will spool real fast wont it

 

I just think that you will have problems making sufficient boost that way. But i freely admit, i am no turbo expert.

 

Just the idea of all that piping turns me off. LOL Twin turbos is all you need to look good and have performance. Yeah its cool to be different and to take up a challenge, but different and just plain silly are two different things. JMO, so do what you want. I am a performance guy so unless quad turbos would benefit me, i wont do it.

There has been a quad turbo race motor built that puts out over 2500hp up to 3000hp depends on how its set up. John Meaney had something to do with this. he went quads because its different and wanted to try it. It seems to work so good that they arent allowed to use it in competition. LOL

 

im from the school where more is better and to much is just enuff

 

thats sounds like a good school. maybe i should transfer and leave Pitt. LOL

More power to ya! Best of luck!

 

Hmmm, I didnt notice you in class with me! Must be because I took the N/A curriculum :lala:

 

They might spool up really fast,but even though they are small, you are still cutting your flow down to a quarter of the total for each turbo. Plus, the larger the turbo is, the more effecient. So here you are messing around with four inefficient turbos and no intercooler.

 

intercooler just cools the air right. how much pwr does it add. with the 4 turbos wont it equal the amt of flow as one big one or two bigger ones

 

An intercooler doesn't technically ADD any horsepower at all. Think of it as a lightweight pully x 10. It allows you to make closer to the full potential of your power. You will get more power using an intercooler because it cools the air which helps you make more power, and reduces the chances of detontation, which will destroy any motor (not matter how built) in a matter of seconds if it's bad enough. Except for diesels, which run off of detonation, which is why they are so badass.

It sounds to me like you are getting way over your head here.

1) If your motor is built up for N/A, you can go ahead and cancel your turbo project right now.

2) If you'd like to go ahead anyway, I strongly suggest that you go buy at LEAST two good turbo books. Two that I recommend are "Maximum Boost" by Corky Bell, and "Turbocharges" by Hugh McInnes. Also start spending a lot of time in the Power adder section on this board. You are in a world of pain, frustration, and trouble if you go into this as clueless about turbos as I think you are.

 

It's hard to say if they will equal the flow of a larger turbo because they will be less effecient. So even though they'll be compressing air, they'll be doing a worse job of it, so the air will be hotter and less dense. Think of it in the same respect that one 4" pipe flows more than two 2" pipes.

 

WOW did they guess the times in that list?


I was going down the list and man. some of those times are way off.. GTZ? do they mean the gtu 2.8? because the gtz is deep in the 15's

The camaro l98 was already caught and mentioned above.

a low 14.0 89 TTA???? ouch maybe they passed out while running the 1/4

if you take a good look the times they are all over the place

 

intercoolers make it possible to run more boost I hear cuz they lower the temperature like you said of the incoming gasses and thus reduces detonation and lower air intake charge means more power.

Why do procharger kits have an intercooler? The blower doesnt run off of hot exhaust so why does it need an intercooler. They say it makes more power with the intercooler than non intercooler centrifigual kits so whats the deal?

 

because the heat made by compressing air (makes heat very rapidly) and I am sure the open cone filter over the header on out thirdgens makes it that much worse

 

yea but this is going in my a body elco i got lots of room

 

As of this point in time, I've yet to see any evidence that shows that the difference in a cone filter right on the compressor, compared to a cold air intake makes a significant difference to justify even the small amount of work it takes to build a cooler intake.

In fact, since the turbo is controlled by boost pressure and not heat, I'd think that the only benefit to starting out with cooler air is that the turbo doesn't have to work as hard to compress the air. Then again, I doubt that the difference between underhood temps and ambient air even makes a noticable difference in work to compress said air to the turbo anyway.

 

stu, it's a supercharger

 

yea a centi just looks like a turbo but its really belt driven instead of exhaust. i think it goes like this cone filter to intercooler to sc because it gets pulled through the intercooler first it is compressed more but i dont get how it would keep up enough volume to keep it filled with cold enough air i would assume after awhile it would just pull in ambient temp as it is pulled through the intercooler and not shoved through.

 

What's a supercharger?

You guys do realize why it is both pointless and stupid to put an intercooler before the power adder right?

 

yea thats why we dont get why thats why he was asking

 

of course putting a intercooler before it is compressed is like
