Shouldn't I be running faster than this?

[95DSMTurbo]

I have a 95 FWD with the following:

T-25
3" intake pipe and cone filter
Dejon Tool upper IC pipe
TiAL 50mm BOV
2.5" o2 housing w/ dump tube
3" downpipe
3" cat-back
Walbro 255
MBC set at 16 psi

To date, the best times I can pull at the track on this set up are in the 14.7's. 1st and 2nd gear feel strong but the car craps out in 3rd. I have pressure tested my intake system and it holds 20 psi reliably. Some tell me that the combination of a 3" turbo-back and external dump tube is too little backpressure for such a small turbo. Others say that my slow times due to a lack of tuning equipment. (MAF translator coming soon!)

I plan to get a 20g soon...but I'd like to make sure something isn't majorly wrong before I make more modifications. Any advice would be greatly appreciated.

Assuming that you have a 5spd, yes your car could be faster than that with your mods. It may be true that you have "too little" back pressure for the small T25, but I have a feeling the main problem is that you are running really rich since you don't have a fuel controller for that 255lph pump. Either get an SAFC and tune it right or put the stock pump back in and I bet you'll be considerably faster.

 

[CBgst]

I agree that your probably running a little rich. An afc will not help because your over running the factory fpr so you need an afpr. There's also no such thing as not enough back pressure on a turbo car. The smaller turbo actually makes more back pressure so you want to open your exhaust as much as possible. You should be faster but alot of factors go into a time slip. What 60' and mph are you running.

 

[DSMJim]

The running rich factor goes on. By your list it says you have a Tial 50mm BOV. To the best of my knowledge you can not re-route that BOV either which is going to make your car further run rich because your BOV is installed incorrectly on your car.

the tial BOV is vented right? there could be some of your problems.. also my friends with t25s can only pull low 15s up here so dont feel bad.. are you awd? when do you shift at the track? how are your launches?

i can shead some light on what u should be running, but i dont know whats wrong with ur car that its not running that already
my friend has a 96 fwd with the stock t25 at 18 psi, 3" turbo back exhaust(stock o2 and manifold), injen intake, big front mount IC and IC piping with a 1g bov, and an MBC, no fuel mods what so ever
he is running mid 13s, u have a fuel pump so u should be running at least that fast, the front mount doesnt really add any power, ur stock sidemount should be good to run low 13s on if need be, ur problem might be the o2 housing, but u definatly should be running in the 13s with a decent 0-60 foot time

It's definitly not the o2 housing and what does a feul pump have to do with his time. How do you have a 3" turbo back with a stock 02 housing :laugh:. Also a fmic does help even if it's on a t-25. I also seriously dought your friend is running mid 13's with a fwd and those mods. If he is then i'd say he's one of the few and far between to that with a fwd. What exactly do you consider a decent 60' time?

 

[1994supertalon]

14.7 isn't bad for a fwd t-25. Those turbo's are junk, wait till you upgrade then you'll have no where to go but faster.

 

[awdfun]

Bein's how your FWD, I'd say those times are not bad. Gotta see your 60 ft times and 1/8th and 1/4 times and mph's to comment any further.

FWIW, I have AWD and similar mods. I have had my car to the strip once and ran a best of 14.3@92 mph (1.89 60 ft), and that was at 15psi and full weight. I'll move on to another turbo when I can run consistent 13's on the t-25...

 

[loreak]

ok what you really need to tell us is your trap speed and 60 foot, i mean 14.7 tells us either your not launching hard, or your trapping really crappy

if you can hit 13's on a t25 then thats impressive, but i would say 14.7 is about right, maybe low 14's with a killer launch, i ran a 15.3 at 94 on my t25 2g with a 2.4 60 foot.....stupid auto wouldnt launch hehe

 

[Syndicate13]

Buh, my friend matt has a 96 gst, we ran a 14.6 with an air filter and free mods, with the ram air mod, You should definately be running faster!!!definately 13's. Whats your 60' time?? cause his is a 2.2 on bald street tires. TIres, venting or not, and other things may be a variables in your time.

 

[95DSMTurbo]

my trap speed is usually around 94 mph and my 60 foot time is about 2.2 (due to fwd and stock clutch). as for shifting, i used to take it to the redline, but the car pulls better times when i shift between 5500 and 6000 rpm. i am also running on 17" wheels with low profile street tires, if that makes a difference.

also, the Tial BOV is vented, but i am switching to a GM MAF blow-thru setup soon. The MAF translator will allow me to tune my fuel system, just like an S-AFC.

what i gather from your guys' responses, is that my problem lies in something simple like fuel tuning and not something major. therefore, once i have my blow-thru setup installed, i'm going all out with the 20g!!

thanks guys!

 

[azteck2]

If you ever figure out why your running so slow, let me know! I also have a FWD but mines a first gen. I have a 20g 3inch O2 with external dump, 3inch exhaust, GM mass in blow through, afc, 660cc inject, fmic, web cams, feul pump, full tunable suspension, and Tial BOV. My quickest time at the track is a 13.5 at 105mph with a 2.4 60' time. I know part of the problem is wheel spin all of first, second, and top of third, but I thought my mph would be killer, but it's not? Sorry to jack your post but I'm looking for answers too....BTW i have a logger and running 105 race gas I have 1-3 knock sometimes and my O2 voltage is around .88 most of the time.

 

[Cirus_93TSI]

ok, as for my friends fwd tsi, i say mid 13s because of 2 things, we keep racing him against cars (from a roll and stop)whose times we know, only ones with consistant times from a stop
as for the 3" downpipe with the stock o2, i dont know how that works, u would have top ask extreme motorsports about that, they put it on and sold it to him, it is full 3", it came off the car of one of the guys that works there
i saw it run a 14.5 with my own eyes back when he got it, it had a 2.5" exhaust, was on 15 psi, had a smaller griffin fmic(it now has the biggest one greddy makes), didnt have the upgraded radiator(i forgot about that) , and had a slipping stock clutch that didnt allow for any kind of a launch
it now has a clutch masters stage 3 2500lb, is on 18 psi, has some prothane motor mounts, has the full 3", it smashed our friends civic that runs consistant 14.4 by at least 3 cars, so it has to run faster then that, and it feels much faster then when it ran 14.5, from what it runs with i say it runs 13.7, but we wolnt know for sure for about 2 weeks when we get t take it to the track, he has to break another 2500lb clutch in cause he blew the tranny to pieces racing a new lightning

 

[Cirus_93TSI]

of i forgot, it also had a stock intake when it ran 14.5, now has a nice injen, and it also has been on 17" rims with low profile tires since he got it
and i would suggest u shift at 6200, that works well for most of the people i know driving 2gs, u definitly need to invest in a clutch and i suggest some solid motor mounts to help with wheel hop, fwd can definitly be very fast, rob from extreme motorsports ran 10.70 in his 90 fwd a few weeks ago, im pretty sure its well under full weight, and it has lots of work done to it, but its impressive none the less to run 10s on fwd

 

[loreak]

ok first off, dont say he runs mid 13's because you raced some car that supposedly runs mid 13's.......a fwd t25 aint running anywhere NEAR that, a 14.7 at 94 is a tad bit slow for you, i would say you should be trapping 96-97 at most and you cant do a whole lot better then 2.2 60 foot

dont listen to what people are saying, your car is running slightly slower then it should

 

[WhipmastaFlex]

you suck at teh driving

 

[Cirus_93TSI]

i never said that guy was supposed top run in the 13s, he should be running like 14.3 on a stock clutch with the mods he has
and im talking about my friend running almost a dozen cars who have recent timeslips from within the month, it doggs our friends audi tt quatro off the line bad, i mean if we race it from a roll against a prelude that ran 13.8 a week before(we did this before the tranny blew) and its side by side, neither can pull away from the other, and it takes the prelude off the line by 1 car in first gear, then that tells u something, plus the g tech hks turbo timer says it runs a mid 13, but since that doesnt include any reaction time it isnt realy accurate, i will post a timeslip for it in about 2 weeks to dismiss ur doubts about it, if a clutch, intake, a half inch bigger exhaust, and an extra 3 psi doesnt drop from i4.5 to a 13 then theres someting seriously wrong
the point i was trying to make was he ran 14.5 with far less work then the topic creator has, and now their cars have almost the exact same set up except 95dsmturbo has a fuel pump and doesnt have a fmic, and they have different bovs, he is running about a half a second slow for what mods he has
and i strongly suggest u(95dsmturbo) invest in motor mounts and let off the gas if ur wheels ever hop, wheel hop blew my friends tranny and if u blow urs u will find 2g fwd trannies are pretty hard to come by and cost about twice as much as an awd trans, he got his for 950 used, ouch, cost him 2k after replacing everything that got hit and ruined by the gear that it shattered and threw(clutch, labor, ect)

 

[loreak]

actually some of those new g-techs are insanely accurate, the old ones sucked really bad, but my friend has some new one thats not really well known and he ran it at the track 3 times in 2 different cars, it was exactly on every time, off by like .5mph and almost exact on ET

but realistically i would think a 13.9 at best

Well that, or just get a FPR and lower the fuel pressure back to stock pressure...

That and a 14b upgread.. that would help a good bit.

 

[Ricardo]

Hey man don´t listen to the guys saying you are running slow, that´s bullshit! I think you are just about right... your problem is the piece of shit T-25 turbo, that turbo sucks ass, get a decent turbo and some injectors and you will be where you want to be.

2.2 is NOT a bad 60´ but 94mph is a little lower trap speed than it should be, but that´s because your turbo lacks top end. Who knows, the turbo might have a little shaft play or maybe your engine lost a little compression... but that´s nothing! My friend ran 15.6 on his gs-t with only a catback exhaust. It´s nearly impossible to have your vehicle running 100%... I SAY YOUR CAR IS FINE, DON´T WORRY.

 

[HoBoJoe]

What have we learned???? AWD is the best ever... i ran a 13.9 with a intake, uicp w/ 1g bov, centerforce clutch, plugs/wires, and a 2.5" test pipe.... stock cat back...

Shush, The 14.7 kid can take you from a roll.

 

[Frontwheeler]

Lots of people talk about how fast they are because of some car they raced on the street, but it all comes down to driver skill at the track.(and traction also for FWD) And anybody that's actually taken there car to the track will probably back me up on this. My friend and I both agree that my talon is faster than his mustang, but he still walks all over me on the track becuase he is a very experienced driver.
