first win with the turbo

I just got my car out of the shop, and decided to cruis around for a little while. I was sitting at a light and a probe gt pulled up next to me. He started revving so I said what the hell. I revved back keeping the turbo quiet, and when the light turned green I easily walked away in second gear. It wasn't much of a kill, but it isn't running perfect yet. It did put down 180 hp and 205 ftlb which is really good for a 2.0 gti.

Coolness

:thumbsup: I like it!

welcome, good kill with yr new car.

Finally a VW on this forum. :smile:

:(

it's because i don't have a damn turbo isn't it????? well, i have what no turbo will ever have...ummm a nice exhaust note :icon16:

hmmmm...why would you wanna keep ur turbo quiet? dont u wanna let him know that he messed with the wrong gti? i raced a supra and when i heard that turbo, i was like "oh shii!!!TT" http://www.automotiveforums.com/vbulletin/images/smilies/icon16.gif

you take off the damn BOV which just wastes power anyway. doing that will make the turbo car much quieter, and it'll be better in terms of power once you start modding. I can explain further, but i'm just lazy :iceslolan

Forced induction rocks! :grinyes:

By the way, removing the BOV is not a good idea. It is there to prevent compressor surge, which can kill a turbo really quick. :bigthumb:

too late, you have to.

The reason I was trying to keep the turbo quiet was because any other time I let them hear it they backed down. Even a WS6 which I figured would smoke me anyways. The only people that would mess with me were rockets and why waste 93 octane. Do you guys think 10 psi is too much boost if I have enough fuel? I hope not because I really like it. How much power does a stock srt-4 put down to the wheels?

ovbiously there is always the chance of a problem, but...


Think of the turbo system as a closed circuit. The car knows exactly how much air is in the system (from the maf). If you use a BOV, then the air is vented to atmosphere instead of back into the system (like stock). This is detrimental becuase the recirculation is after the air gets metered. If you vent the air that ECM thinks is there, you are making the car run rich.

The difference is probably negligable in a stock application and probably not enough to determine the outcome of this race, but gets propounded as the power levels go up.


just got that ^^^ from one of the guys on another forum. he's kinda the audi/vw turbo expert.

I think the SRT4 is supposed to put down 230hp.

sigh... would you not say oh shit when u realized it was a supra in the first place, considering u have a corolla?

How much does the srt-4 put to the wheels? I know a BOV hurts the 1.8t but every other car I've seen runs a BOV. This is not a 1.8t it is a 2.0.

:thumbsup:

putting a blow off valve that is vented to atmosphere hurts performance on 99% of air flor metered cars. so what most people who actually care about performance do is by a blow valve that also can double as a compressor bypass valve. this allows the the excess boost to route into the intake after the MAF when the throttle is closed so there will be little or no sign of running rich. that is why most DSM and 240sx guys runs the greddy type S.

BS!!! dat probe woulda put the biatch slap on you volkzwagen homie!! dem probes are maaad tyte!!








j/k...good kill....i drink too much of that caribou coffee stuff....gives me the snappies...

Remove the BOV.lol Great idea!!!http://www.automotiveforums.com/vbulletin/images/icons/icon14.gif

Like Tat said, recirculate it. Or depending on what kind of fuel tuning you use, there may be a function that will allow you to vent the air to atmosphere. The SAFC 1 and SAFC 2 both use a Dec. air setting that detects when you let off the throttle and automatically sends correct voltage to the ECU at 2k and 1k rpm. Requires a lil bit of tuning to perfect, but I think it works well.

O and for your "Keeping the turbo quiet,".... Get a bigger turbo.:p

Ehh i thought SRT-4's were rated 230hp at the flywheel and put down 215 at the wheels?

sigh... would you not say oh shit when u realized it was a supra in the first place, considering u have a corolla?

its kinda like a huge ass roller coaster, at first you see it, ur like..."shii!! dang".....then when ur up there freakin hundred of feet high, now ur like...."holy shi!!" get my point?

dont matter how fast this supra was if the driver didn't know how to drive, dont matter how fast ANY car is if the driver dont know how to drive the car

Ehh i thought SRT-4's were rated 230hp at the flywheel and put down 215 at the wheels?

I'd believe it. I didn't really know I just thought I remembered hearing 230 somewhere. I will go with 215 unless someone else corrects me again haha.

after the air gets metered. If you vent the air that ECM thinks is there, you are making the car run rich.


Which gives you a nice fireball if you have the proper exhaust set up...I think it needs to be decatted, right?

if theres no cat then yes a fireball would shoot out when you left off the throttle. also a Stock SRT-4 puts down anywhere from 230-240whp stock, and is rated at 215hp for the 03, and 230hp ( or something close to that ) for 04 and 05. the older 03's puts down 220whp stock.

aww ok n/m then

CORRECT, guys I actually just had this problem fixed on my sr20det, it had mad compressor surge pre-BOV that I mistook for a blow off valve blowing off in the first place. Now all that is fixed and my turbo is saved. The guys who put the bov on also explained to me that the sr20det is a fine engine to run a vented bov on and that running rich with a vented bov is mostly seen on DSM's. I'm sure it would require something like that for a KA-T as well, they need a bit of good tuning when they first get the transformation though anyway don't they?

Any MAFS EFI engine is subject to abnormal rich conditions when running a Vent To Atmosphere(VTA) BOV setup. The MAFS reads air entering the intake. When you let off the throttle, a bunch of that metered air is dumped into the atmosphere. So the computer dumps fuel for air that isn't there. AKA, rich condition.

But some cars are "Anomalies," that do not follow the rules of VTA BOV setups. Even some KA-T owners have run VTA setups and had zero issues, even with no SAFC or standalone. I didn't have it too bad when I ran VTA on stock ECU and FMU with no SAFC. A lil bogging but not that bad.

KA-Ts require more tuning on initial turboing than per say stock turbo engines. NA fuel adn timing maps are just not friendly with boost. Esp with our 9.5:1 static compression ratio. ECU tune is basically in order for anyone venturing past 250whp. Anomalies are present, yes. But for most, at 250whp, better timing control is needed.
