Sleeper Turbo Setup Help

[TurboKA37]

if ur looking for a stock looking exhaust but want some performance out of it i suggest the RS*R exmag exhaust. i think its about 2.5" in diameter and sounds pretty quite from what i hear.

[SloS13]

Ive got a starion intercooler painted black. I tucked it up high and had the bumper support cut for good airflow. its virtually invisible

Hey, detforme, how do you like your blow through setup? Are you running and atmos. BOV? Did the blow through solve the stumble? How did the more accurate temp. readings effect your fuel maps?

[detforme]

i like it a lot. the idle is pretty good, except that i put the vaccum line for the iac in front of the mafs. it should go behind it. but the car still runs fine most of the time. stumble isnt to bad because i picked up the idle to about 800rpm. yes i have an open atmos. bov. my high throtle fuel map is stock. the low throtle doesnt really need adjusting either. but i have it set a little rich just to be safe. ill have it at the track in a few days to let everyone no my times. i did learn that the mafs reading at 6.53lbs on my setup is at 99.3% of measureable air.

Thanks, I'm thinking about running mine that way.

so does anyone know what the flow in CFM on a stock sr20 exhaust is? nobody really talks about anything other than the front clip. does it use the same exhaust? maybe someone can get me a part number from an FSM or something...

[aleph1]

haha. why even bother, its obviously very restricting as if you even move up to 2.5" you gain HP...

Youd notice better power from a 2.5" system with an added resonator from a muffler shop, than wasting time with a stock SR system...

"nobody really talks about anything other than the front clip. does it use the same exhaust?"

Uhm its a stock front clip, I would imagine it used the stock muffler?? What kinda of question is that?

[tfj]

i meant does it use the same muffler on the SR as the KA...

[red240ne]

i meant does it use the same muffler on the SR as the KA...

They don't give you the stock exhaust with a front clip, if that's what you're asking. I bet it's just as restrictive as the stock exhaust on U.S. 240's.

[aleph1]

it looks to be the same dual tip one...

[MarkEmark]

You don't need to run a BOV, unless you just want the sound...I think it'd get annoying after a while. i'm running a compressor bypass valve, otherwise known as a diverter valve, from an Audi TT...works fine, sounds like a BOV under hard acceleration, plumbs right back into the intake...I think I'm replacing it with a CNC'd aluminum unit from Forge motorsports soon, however, just for a crisper sound.I was checking out DSM side mount intercoolers, and I think the first generation DSM aluminum ones would work perfectly for my setup, anyhow...theres 2 holes going into the driver side wheelwell, one is the inlet for the intercooler, one the outlet Less piping than going front mount, anyhow...

[TopStreet240]

OR you could mount the intercooler, perpendicular to and on top of the radiator...like this:

{=====} <---Intercooler /\|||| <---Radiator||||\/

Then have like a scoop or something for the air to go in where the grill is (a la a Starions intercooler setup) and then maybe a vent on the hood to let the air out. This is the setup on Signal Autos "Drifter XL" car. This would probably be more effective if you have a Silvia front.

the problem with the top mount intercooler is that you loose a ton of efficency. air does not flow as well to the intercooler like that, so he is better off running a side mount, or a air to water set up

[TopStreet240]

the exhaust i would use would be a 3inch exhaust with a (either greddy HKS or Blitz) twin tip muffler (looks close to stock) people would never know what hit them.

what if u used some type of upside-down scoop to force the air into the intercooler. that would help out

[TopStreet240]

The problem with the top mount is that the air does not flow evenly across the whole intercooler. a up scoop might work, but you will still not make as much power as a front mount. Take the subaru wrx for example. The top mount intercooler is okay but it is taking engine heat and having to work twice as hard to cool the air being forced in. In a study done on the rx7 (also top mount) the removal of the intercooler gained something like 30hp.

[aleph1]

Why would Signal use this setup in BOTH professional D1 drift S13s, Drifter X and Drifter XL? If this was truly a bad idea, there was plenty of time/room for improvement. Remember they are a major tuning company and both of those cars are 99% the same, they must know something.

BTW- You are mistaking the setup I am talking about, NOT TOP MOUNT. The IC would be on top of the radiator, betwen the front of the car and start of the block. NOT ABOVE THE BLOCK, like a WRX or FC turboII.

[TurboKA37]

but...... the signal cars are rarely going in a forward motion so there is much less of a decrease in performance

[fritts]

Signal from the shots I have seen, does not run a front mount radiator and directs the air directly from the front bumper opening up and to the intercooler. Ihave no Idea how they are cooling the engine. But I am sure their setup cools a whole hell of alot better than a top mount on a car with a regular radiator would.

[WongFeiHung]

I'm thinking they went with this setup for good throttle response and to reduce turbo lag....

[WongFeiHung]

and

[aleph1]

I believe Wong is correct. Although I never said this was the most efficient way to use an IC, if any of you thought that. The original plan was to have the IC out of sight, and I figure this would be an interesting setup, as you would gain faster response at a cost of less IC efficiency....

[Projex240]

I like the way that looks....that is freakin sweet.Even the dsm bov would give ya away, and the turbo will make the typical ssssssssssss sound when riding next to someone at high rpms.

[SloS13]

sorry for the crappy pics, but why not just paint the IC black. makes it basically invisible

[float_6969]

Cuz black absorbs heat. I dont know how much difference it would make, but I still think it would make a difference. (prob negligable, but it sounded smart ;D)

[illspace]

First of all, yes please use the stock exhaust, most of the fast cars around here do, but they use something called an E-cutout, when you hit the button it creates a dump right after the downpipe. They are slowly gaining popularity around the country, and it all it cost is about $150 and you get the to keep the stock exhaust. On top of that, it flows better than ALL aftermarket exhuasts. Also I advise using the black starion IC, but if not, I would attempt doing the top mounted IC, becuase its so trick. Also I would do the Hacked MAF.

[SloS13]

Black absorbs heat if it's in the form of light. its pretty dark down there, plus it gets plenty of cooling. Mr Wizard! :pface

[float_6969]

I told you I was pulling **** out of my azz!

[erich]

Quantum mechanics says that a perfect absorber is also a perfect emitter. Black is the best color for absorbtion therefor the best for emitting. The only problem is that paint is an insulator :-( Perhaps the guys a swaintech coatings have an ideal coating for this application.

[SloS13]

i put just enough paint to color the intercooler and no more. i figure it'd hurt my efficiency by like 1%-2%
