hehe kinda dumb question but whats stock boost on my car? just wondering if its worth it to install a boost controller and gauge without bov thats all. thanx

your 8th mile time and trap speed is amazing. I ran a 14.0 @ 95 with a 1.79 60ft but my 8th was 8.9 @ 76. Nice driving!!

btw, what rpm are u shifting at?

Hey thanks man

Hey Q i knew it was you once i saw that title,haha. Its kyle. Yea i have a piuc of his time slip,ill post it up, i also have a video of him running it but im too lazy to piost it up.


Its true that it really wasnt stick though,b\c the exuast was disconnected from the downpipe and a boost controller was put on and maxed out(even though woudlnt go past 15psi anyways) also headlight was taken out. And even though its not really an aftermarket clutch its a autozone clutch,so u cant say its stock.

otherwise though its a miracle this car ran in 13's! it looks like the biggest beater,if you ever lined up with this car at a lite u would prabably laugh if he wanted to race you, but he has good launches\shifting cant argue that.

THIS IS AT NORWALK RACETRACK IN OHIO,this might be a different run then he was talking about though because that was the second time he ran in 13.7's

Yea the day at norwalk I had a different set up and AUTOZONE Clutch is weak trust me my friend its a OEM shit replacement. Anyways thanks get the vid up lets see it haha. Anyways yea my last set up was different aight welll thanks and my car look like a beater that dya i got the new tails and a detail job looks nice

So if I take my testpipe off the car, that will leave enough room for the exhaust to escape?

-will that net any performance gains if I have the usual mods, intake mbc 1g bov uicp..

-also my father seems to think that running an open downpipe will fry the valves... he said thats what would happen if you let his camaro run around too long on open headers... he's cool about my car though because he tells all the local muscle heads that its quicker then they think.

any input guys

thanks!

This is the car that did it... haha Kyle its a beater that day I made it seem like one

Dropping the Exhaust will not hurt anything as the Turbo creates all the backpressure your ever gonna need.

pretty good times, i was only able to squeeze a 13.9 out of my stock t-25 stock boost but with intake/exhaust, but my car is auto, so i lose alot there, but my 1/8 mile was 8.8 at like 76, and the trap was around 96 for the full 1/4, but i had 1.8x 60 ft.'s in the stock auto tranny too

Nice, 13.9 with two mods sounds nice

To the orginal poster, keep up the good work, those are great times.


Gives me hope, I just have no traction

 

[96TurboAWD]

what rpm do you shift at?

I shift at 6500 or right between 6 and 6500

 

[Blazin632]

i seriously doubt u ran that on stock boost. specially if my friend ran 14.6 with just the free boost mod and gutted interior on his 97 gs-t. he was trapping around 96-97ish if i remember right. and his 60ft times were pitiful..about 2.4 if i remember right.

stock on stock GST vs a GSX.. would the AWD take over the FF!?? i would think so

 

[Blazin632]

my bad for not reading his sig and seeing he had an awd. but i still don't think he'd run 13 on stock boost. what all bolt-ons are on this car?

Ok the first time I ran 13.7 was with this setup.

Open Exhaust from the 02 letting it spike to 12-13
Aifilter
1gbov
and 60 degree temps

2nd time this set up

Open Exhaust from 02
MBC set at 15psi
1gbov
filter
and mid 60 temps but I had a problem I ran better with out the MBC

Your friend had a 2.4 60 ft., he had a 1.8x 60 ft. that is around 5-6 tenths already, that right there would put your friend down to a 14 flat or better, and the fact that 1/10 on the 60 ft. is like 2/10's off your quarter would put him into the 13's if he knew how to get out of the whole or could get traction. 13's on stock boost/turbo is very possible.

 

[GSXRACER20PSI]

the search is down so i figured i would just ask. what is my stock boost. i have a 1990 gsx 5spd

 

[mister2sw20]

10-11psi

 

[L8TR V8S]

Hey guys... i had a quick question i have a 95 awd talon with a evo III big 16g turbo and evo III manifold, maf translator with 3inch blow thru, 3 inch thermal exhaust turbo back with no cat, 680 cc injectors 255 walbro fuel pump... me and my buddy took it out and raised the boost, its boosting 22 psi is this 2 much for the stock internals... the car has 77,000 mile on it???? please let me know if i should lower it or not and possibly 2 what psi????

thanks

 

[95blackGsTurbo]

As long as you are running a good tune you would be alright. I don't see any form of fuel control on your list which would be a bad thing. I would suggest investing in DSMLink if you get a chance. 22psi might be a bit excessive for a EVO III. I would at least get a pocketlogger first to check for knock and see how much timing you are advancing/retarding. I would keep it down in the 17-18 range until you can get a good tune on it to ensure you aren't going to hurt anything. Other than that the only thing I would check would be that your timing belt its good and might consider replacing the headgasket just to be safe.

 

[L8TR V8S]

hey thanks... well i don't have any fuel managment but the headgasket i just replaced and the timing belt might have 1000 miles on it now so maybe ill knock it down a bit and i was thinking to 17 to 18 psi thanks for your help... another thing is i had my air to fuel ratio checked and i was in between 11.8 and 12.1 which i think is perfectly ok??? correct me if im wrong

 

[95blackGsTurbo]

Yea those numbers are fine. How did you test it for A:F and was it consistant throughout the RPM band or did it jump around. I usually tune for right at 12.5. The leaner you are the more power you make but you also run the risk of burning stuff up. I wouldn't go any leaner than 12.5. Other than that looks fine.

 

[L8TR V8S]

Well my buddy bought a a/f gauge i dont know if it was from AEM or something like that but that hooked up to the battery and then we ran the sniffer into the exhaust and it read it perfect from what i saw i was only pushing 10 psi at the time and we richened the car out at first and slowly raised the boost until it evened itself out... and full boost at like 90 - 100 mph, 5000 rpm the car felt solid and had no bog or anything....

 

[ddavisaf]

11.7:1 is "perfect" AFR. I wouldn't tune it to more than 12.3:1 personally.
If you still have a cat on your car then the sniffer test will not work.
You need a wideband O2 sensor and gauge.

 

[L8TR V8S]

yeah i know 2 do more tuning i would need something other then what i used to do that but i just wanted to make sure that, that boost would be ok to run... i will more then likly drop it down to 18 psi but i think its ok for now... thanks guys for the help!!!! i was wondering what can our stock internals handel horsepower wise and boost wise with 77000 miles, thats what i have now...
