2g gsx put down a 14.075 on t-25

[Spyke169]

That is my slip from the other night, mods are intake, cat-delete dp, catback, bov, mbc is turned all the way down and boost is about 13psi. Should I be faster? or is that about as good so i'm going to do with those mods? I'm getting upper intercooler pipe. I kinda wanna see how far I can go on the stock fuel set up. I'm thinking about getting motor mounts, would they improve my time? what else can I get besides fuel mods?

The UICP will help you some, but try turning the boost to 15 psi. Does Injen intake = pipe and filter or just pipe? What are your shift points? Your 60' time is respectable, but with a slightly lower one in the 1.6 range you'll be in the 13's. Hell, with your mods now and a 1.6 60' you'll be in the 13s.

thanks man, the intake is the pipe and filter. Launch at 5000 shift at 6500 every gear. What would help to bring my 60 down besides a clutch? i'm 17 and am still in school so i'm on a some what limited budget, would motor mounts help my 60'?

FWIW, I picked up 5 tenths and 5 mph on the T25 just by adding race gas and setting boost to around 20 (dropping to ~15 of course). I was running consistent 14.2s on pump gas. My mods were similar. Filter, exhaust, MBC, UICP/1gBOV, 2600.

Thanks, I may throw some in next time I go down, it is like $6 at the track, But i'm looking for a place locally that I can get it for less. Whould I be safe running 20 psi on race gas with the stock pump and injectors?

Thats pretty good ...I have achieved only a 14.3 @ 97 with the mods I have.

Thats exactly what I did. Let me try to sum it up quick. Just an exhaust, ran 13.6. K&N filter, dropped to 14.3 (must have been more from better driving since I was still learning). BOV, UICP, profec B, logger, 2600, ran 14.2 Thats teh best I could do on pump gas with no fuel control on the t25. Raising boost didnt help power, and it didnt help timing. Adding race gas just gets rid of the knock I was seeing allowing full timing even on the higher boost, and that dropped me to 13.7 and added 5 mph. IT cant hurt, I would give it a shot. If there is a big change, odds are you were getting knock. Its not exactly ideal, running race gas with no fuel control (to lean out), but it still adds power and safety. Good luck.

ahhh... question?? what kind of Race gas specifically? and where could I get it? how much is the cost? and could I put in a full tank of this stuff? Im askin cause I run 20psi (drops to 15) on the street, and I would love to pick up a little more speed on the t25.. So if I dont jam on the throttle all the time will it still be safe? mods are in info... and I have no fuel control.

14.0 on a t25 at 13psi on pump gas is pretty scary. u must have a freak car from the factory.

I would use 100 octane, anything more than that tends to have lead in it, not only will that plug your cat (if you still have one) but it will shorten the life of your O2 sensor. At the local track it costs about 5 to 6 bucks/ gallon. Some people do a tank of only race gas, some mix race with regular. I have been thinking about using race gas for a while now, but havn't yet, I like to run at the track what I run on the street. I might throw some race gas in this next season, not sure yet.

 

[Spyke169]

95GSXracer, how did your 60' change from b4 and after the clutch install? I'm hoping to get into the 13s this next season with a new clutch and the safc I just installed. I really doubt the safc will do anything since I only have it leaned out high throttle 4-500 1% and 6-8000 3%

Thats what I'm thinking
