KA-T vs WRX vs SRT4

[illspace]

what is your turbo setup? The WRX sprayed, b/c no other way it will pull in 4th, I know this. The WRX also must of had an aftermarket turbo, b/c the stocker is out of efficiency a lil over 15 psi. Stock boost on both cars is roughly 1 bar, normally a lil less.

[lessthanjakejohn]

wrx and srt probaly have less power at 21 psi than they do at 14

[stilesg57]

Well, there's no way the WRX was running at 21psi on the stock turbo - it just won't do it. ECU sees something like that and goes into limp mode after the first det. event and also cuts fuel at anything more than 19psi (20.5psi if he also had the FCD).

Also, if he pulled on anything faster than the highschool track team in 4th, he had to be spraying. 4th is actually an overdrive (.97something) on the WRX and it SUCKS. Are you sure fourth? WRX's hit fourth around 85 mph, is that where you were when he started really pulling?

Good to hear the 9psi KAT did so well, but those fools were lying to you really bad.

[andrave]

yeah I don't think srt or wrx stock turbos would run at 21 psi... and I think that would prolly blow the engines if they were stock anyway.

[Kadath128]

So... what your saying is around 12psi and I should be able to peek ahead on them?

[tl1000sga]

Isn't 1 bar about the same as 15 psi?

[tl1000sga]

98KA24DET, What kind of times and hp are you pulling with that set up?

[s13conv]

1bar = 14.22psi

[cnichols]

I thought,

1 bar = 14.5038 psi

and is more often quoted as 14.7.

[s13conv]

I got the 14.22psi from here: http://www.columbusdsm.com/res...n.htm

I have seen from 14.22 - 14.7

For my HK$ boost gauge and EVC IV I usually go by 14.7

I'd rather assume more than less.

[tl1000sga]

Safer that way.

[tl1000sga]

what kind of times do you think you could pull?

[BadMojo]

Now correct me if im wrong but the WRX and SRT4 do not run 21 psi on stock boost out of the factory... right..??

I've been doing a lot of research on the SRT-4, and I'm pretty sure a stock SRT-4 won't see more than 14 psi, depending on conditions. No way should it see 21 psi.

Dunno about the WRX.

[3rD GeAr]

i think the stock turbo on the srt-4 is efficient up to 19psi.

[Jookmasta]

my friends srt-4 is runnin 19-20 at idle and in first gear his gauge is reading 23-24. he has redid the exhaust but nuthing else to my knowledge so those boost levels are possible for the srt-4

It can't possibly be stock b/c the ECU won't let it go past the 16-17 PSi (and hold it) past 5000 RPM, let alone idle. At redline, the stock SRT4 bleeds off boost to a point where it's only at 11 PSi or so...

[S14Swap240sx]

im suprised the wrx didnt blow the welts off its intake manifold with that much boost!

haha what a load of crap.. u where lied too. =(

hey ur ka-t did great tho just keepin up with those 2!!!

are u sure they wrnt pintos with a wrx cover on em?!? i dont think they could lie to u much more then they did

I've never heard of an SRT-4 running anything close to that much boost. Either your friend has done more mods than you know of, or there's a problem with the car.

[jdmfreak]

Hahaha! A big *** lie indeed.

[Jookmasta]

well it was tuned at a shop, but as you know, every srt owner wants to retain the warranty so the ecu wasnt messed with. he does have a boost controller but i dont know. he might have other mods but the boost gauge was reading 19. but when ur driving around it stays in the 10-15 range. the high reading is at a standstill/idle. it does boost above 19 in first gear, but as you know, with a 6 grand redline, you never really see first gear........

[Nebraska240sx]

itsnt like 1 psi + to around 10hp??? then thats impossible for a srt or wrx in stock for anyways dont most turbo vars max out at like 10psi?

[JPRempe]

1 PSi is ususally +6% power over base (on the "average" for turbos)...

Riiiiiiiiiiight... news flash! You don't make any boost at idle... your friend is a dumbass.

[HolyShiznit]

^^ ROFLMAO

[Jookmasta]

officially declared dumb *** of the srt4s

[s13conv]

Uh...19psi at idle? maybe you were looking at a vacuum gauge and not a boost gauge. I don't even know that the MSD DIS would allow you to get that much boost standing still with the clutch in and the pedal floored. I know that my galant w/ the studder box maybe makes a psi or two standing still. But when it's moving runs about 18psi.

[Nebraska240sx]

i thought i smelt ****

[s86d]

ill have to go with s13conv on this you were looking at vacuum or the gauge is crap. I cant talk though I was'nt there but something is wrong...

[solarex]

Riiiiiiiiiiight... news flash! You don't make any boost at idle... your friend is a dumbass.

yup! no way you can get boost at idle; it's the vacuum.

[Thesil]

isn't 1 bar measured in mmHg where in that case, the amount of psi would vary with what sea level you are at...
