I was thinking.... STS says they dont use an intercooler as it gives a higher "pressure" drop. but wouldnt the pressure drop only really be from the cooler air temp, since as it cools down it gets denser and takes up less volume hince the lower "pressure" but wouldnt the actual amout of oxygen be entering the motor anyway so the power should be about the same even with the precived pressure drop. or im a just smoking to much crack?

Reason i was pondering is yest i would be a PITA to pipe in an inter cooler UPFRONT but not a straight throu type ( with say 2 8-9" fans for the airflow ) off of ebay for cheap and make more boost safer?

 

its a lot more complicated than that. If that guy thinks his idea is a better intercooler, he must know something race teams dont. Dont forget that you have pressure differentials and resistance and stuff playing into effect.

Pressure drops, flow, resistance, heat, density all need to be concidered.

less pressure means less flow. think of a garden hose.
even though he might have less of a pressure drop, i am willing to bet a front mounted intercooler will produce more power. you actually want the greatest pressure drop in the least amount of travel as far as i can tell. The longer the travel of the air the more velocity and momentuim it loses.

 

Less pressure doesnt nessasarly mean less flow, looking at a hose, have u ever tried to fill a bucked with the nozel on which would be considers high pressure then take the nozel off and fill the buck. now it looks like alot less pressure but the bucket fills faster because there is more water flow ( ok yeah less restriction i know )

When u have x amount of a gas (as in gas state of matter, not fuel ) v amount of space ( volume ) with h amount of heat ( or energy if you will ) you get p amount of pressure. if you increse v you would have same x but less pressure and if you decresed v you would have more pressure. how ever if you decresed heat ( aka energy ) the pressure also drops eventhough both x and v havent changed since x is now using "less space". therefore you could increse x to bring the pressure up to where it was but now you have MORE x with the SAME v and SAME p so you should beable to make MORE power

I understand that STS has done alot of testing and found that there way of doing it works . but the also say on there site that one plus of there system is you dont have the pain in trying to fit an intercooler up basicly since its a real PITA. which is one reason why they dont want to

Now true you dont want restriction in the way as it would reduce flow and the amount of x getting to the motor but honestly, how much resistance could somthing like this possible add if you mounted it in line with the current pipe ( read parallel to the frame ) not that wouldnt alow any realy airflow through to cool it down like in the front but you could strap somthing like these to take care of teh airflow problem.

Just a though of trying to get the most out of the system WITHOUT resorting to a parasible system ( like meth/water injection as u have to keep refillig ect ) same reason i dont like nos.

Disclamier: If I sound like a jerk i dont mean to. really trying to get this topic explained to me whyits a bad idea if it REALLY is or maybe open other ideas as to what more we could do for mods. again no disrespect to anyone...just im tired and low on bloodsugar ( hands are shaking as i type) i can sound cranky when that happends.

PS to STS, I really like the step up on the system as im going to probaly get one so please dont think im talking trash about you or the setup.

 

I talked to Rick and Dave at STS about this since I plan on running quite a bit of boost with this system once i rebuild my motor to handle it.

Their response is that it is totally doable but that the reason for not including one in their kit is that the length of piping from the turbo to the manifold works like an intercooler. Maybe not as good as a big core intercooler but it also has less pressure drop. If you were to add an intercooler inline you will see additional psi drop which means you would have to up the psi which creates more heat exponentially.

For me refilling the Alky tank isn't sucha big deal because you probably wouldn't need to fill it any more often than you would your gas tank since the Alk doesn't spray everytime you nail it unless you are running a ton of boost 24/7. My kit will prolly have a low setting of 5-7psi for daily driving and it wont activate the Meth kit until I flip to the high setting and start boosting over 8psi (just guessing at boost #s here till I get it on a dyno and check fuel and IATs). So in this example I may only have to fill my tank once a month depending on how many people wanna play with my lil 4x4

If you decide to fab something up and try out an intercooler please keep us informed. Maybe you can find something cheap or borrow a budies who's car is down and try it out. I was also concerned with adding additional lag into a system that is already border line laggy. I feel anything you add inline with this system is gonna increase lag and since i didn't ante up and get the ball bearing option I wasn't taking chances.

I should have my kit in soon and I'll let you know how it goes and if I think you could stand any extra lag. We have plenty of room for an intercooler so if it would be benificial I'd run one along with my Meth injection just like the GN guys do

 

you are comparing apples and oranges. if the cross section is constant; more pressure means more flow. you are changing the cross section to increase pressure.

 

The intercooler will work better for high boost levels OR for extended full throttle applications like towing uphill or other activities in which you will be boosted for longer than short 20sec bursts. The piping from the STS kit will whick away alot of heat when you first nail it but like every other system out there the longer you are at WOT the more your IATs are gonna rise due to heat soak.

Dave was saying there is a Toyota in Texas that added an intercooler to the system and was pushing some crazy 600+rwhp.

But yeah the intercooler will work on the system. They just say it isn't needed because the basic kit is so low in boost that the temps out of the turbo are not enough to overwhelm the cooling effect of the pipe unless you stay in it for long periods of time.

 

The STS system has the Turbo IN the under-truck air-flow too...so exit-tems are going to be lower to begin due to the turbo being cooler

 

I guess what i can do if someone doesnt beat me to it ( although its gonna be a WHILE ) is when ever the time comes I could dyno test, 1 with out intcooler stock pressure, 1 with intcooler stock pressure, 1 with out intcooler high pressure 1 with intcooler highpressure, and try to log everthing. dont suppose anyone wants to donate dyno time in so.cal lol.
