Stock Boost [Merged 5-7]

[Gs-tHaVoC]

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

 

[herostar]

Like everyone says, it all really depends on the quality of the gas, ambient air temperature, IC efficiency, quality of the tune, etc. etc. etc..... I have seen stock 2g turbo engines take 30+ psi though tuned very very well (on a 50-trim)

Hey guys went again to the track and pulled a 13.7 at 97 will have the timeslip up once I get my scanner working. Stock boost with 1gbov and some other lil things but what should be some mods I should get that will get me to that low 13 sec slip.

 

[BacknBlack92ESi]

I have got to see that slip. Damn good times. Too good to be true.

 

[CanadianTSi]

but what should be some mods I should get that will get me to that low 13 sec slip.

A bigger Turbo ! but seriously it's amazing that you went that fast on the T-25 with all the other bolt on's in the worls there's probably only 1 or 2 more tenths to be gained.

 

[Gleason]

how can you possibly be trapping 97mph on 'stock boost' ? most people with exhuast, intake pipe, MBC and race gas cant even trap that high maxing out the T25.

good times none the less.

Anything above 15psi on the T25 will not give you performance gain, so just set your boost to that. Boosting above that amount will just be over working the turbo and shortening its life. You should do some searching before you post a question to see if your question has already been answered. If you want more performance out of your car then read http://www.dsmtuners.com/tuning-guide/2gturbo/ That link has a general upgrade list of what you need for more hp.

well im going to get a big t28 soon. i was wondering if its okay to run the t28 at stock boost until i can get a new fuel pump and injectors?

after i get the supporting mod, which are fuel pump and injectors, is 17psi to high for it?

T28 will be fine with stock fuel and boost.

It will take 17psi with pump and injectors, but some sort of fuel control/injector compensation is recommended(SAFC,DSMlink,keydiver chip, etc.) .

 

[OneFastEclipse]

You should be good on stock fuel at 10-15psi. You could sneak by to 17psi with a fuel pump. Injectors will allow you a little more but you will be reaching the limit of your SMIC. On race fuel, you can get by without a FMIC but it is just a band aid. You will need some type of fuel control whether it be a SAFC or MAFT and a way to log your fuel trims. Anyway you go, your gonna love the new turbo over the T25. Even at stock boost, the T28 will feel a hundred times better than the T25 at 16psi.

 

[SinEclipse]

thanks for the help. i'll be running stock setting with the t28 for about 4-6 months. then i will get an safc, fuel pump, injectors, fmic, fuel regular and tune it for 17 psi

 

[98FWDSM]

I have a ported Big T28 and I am running 17 pounds and all that I have done fuel wise is a rewired stock fuel pump. I have never hit fuel cut but I am imagining that my injectors are running 100%. But yeah, you will be AMAZED that the same turbo in appearance is soooo much better in performance.

Good Luck

 

[Black95TSIawd]

because he drops the exhaust after the o2 housing causing the boost to go up to 15psi. Why else would he put on a 1g bov.

 

[1fstSS]

how much boost can i push through my motor? it still has the 1g manifold and stock exhaust for now, but its disconected at the over the axel pipe, im just curious how much the head gasket, rods pistons ect... will take thanx

 

[griff]

With the right fuel mods, and the right tuning, i've seen 2g's handle well over 400 hp. Stock 1g's can handle even more since they came with stronger rods.

 

[red4G63T]

Great runs

 

[THE_ARTIST_]

AWD sux nice run though can u post the slip?

 

[missouri_dsm]

Talk to hsr98gst he ran an [email protected]. Look at his profile.

You need to rewrite your post to say stock turbo and your time.Stock boost 2gs don't get anywhere near your times. If you are dropping the exhuast you are getting way higher numbers even without a boost controller.

My bone stock 97 ran best of 15.5 at 90mph with a 2.18 or something 60ft. I can see 14s at stock boost with a better 60ft but not sure how much better 60ft you can get out of the stock clutch at stock boost levels.I was thinking maybe a 2.0 flat.

I am at 1900 feet so you can correct that time a bit to 15.2 or so at 93mph but my testing instrument a tazzo vpc reads about 3mph higher than track mph so that 93 corrected is 90mph at the track. I have taken it to local track and checked it against track timers.The et was within a tenth ,the 60ft is right on.

Anyway you are not at stock boost.So quit posting it and making it sound like bone stock 2gs can run your times.As soon as you raise boost by however means the car is not stock.STock turbo yes.but not stock boost.!

Oh sorry sir. Not my fault my car read 10 psi. An yes I didn't even fully drop it it was still coneccted throwing air out the exhaust . And for your information the car ran BONE BONE BONE BONE stock at 14.5 at 94mph got a slip and vid to that. Yes, the car did spike about 12-14psi but shot down to 10 in redline. Anyways your times are decent you need a better 60ft thanks and don't be such a hater. Q

 

[AL92]

Your times are excellent for a t 25 no arguement there. And your 60ft is likely the best a stock clutch can get. Again you have a great 60ft.

My entire arguement is you keep posting it as stock boost.So reconnect your downpipe and run again and see what you get. Then if you still have a very low 14 or high 13 your car is some type of factory freak or you have lightened it,you weigh 120 pounds or
you have negative density air .What is the altitude of your track? Altitude does help.

And I don't hate you for getting good time. I had a 50 trim on my 1g so no a bit about going fast in these cars. Its great a t25 can get to 13s pretty easily.But I bet there isn't 1 other car that ran a 13 bone 100% stock boost on a t25 on the boards.And talking stock weight of car also.

Is your car stripped down,seats out etc?

My bad true well best run with exhaust on is 14.2 thats completely on. The car is full weight and I weigh about 140 AMAZING POUNDS haha. Anyways, sorry for taking it the wrong way nice car your self 97=hot! I am going to the track friday with a MBC set at 18psi with the downpipe a lil open again hopefully i can run a mid 13 sec slip wish me luck
Q

 

[AL92]

I am sure you can hit a mid 13 if you do what you said.You don't now the altitude of your track do you? That makes a big difference. And also curious where you shift at?

My car is currently dead anyway with a few problems.Picking up a 6 bolt core tonite to start rebuilding.Not having much luck with my new 7 bolt.

 

[Kyle2k1]

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
