question about my 1/4 time

[GsxEcutioner]

Hi guys, last Sunday I had ran at the track. I don't have a scanner so I'll post the time slip how it is seen on it.

Car:262 Left Lane
Dial-in: .00
Reaction:.472(i went on green instead of on the last yellow)
I1 60":2.025
I2 120":6.089
I3 180":9.544
MPH(I3):blank
I4:blank
E.T: 14.948
MPH:88.849



Car:262 Right Lane
Dial-in: .00
Reaction:.333(i went on yellow-ish)
I1 60":2.171(i bogged launch)
I2 120":6.265
I3 180":9.725
MPH(I3):blank
I4:12.626
E.T: 15.155
MPH:89.715

my mods are :
mbc 15psi, 14b turbo ported, ported exhaust mani and ported o2 housing, act 2100, KnN filter, high flow at, and greddy cat back, hard uicp, and 1g bov,..............i have no idea why i cant pull better 0_o, my car sounds like its missing, but it isn't, idk, kinda dissapointed.



I'm planning on getting Evo VIII injectors and fuel pump on sat for cheap, and I seen that it is compatible with my car.Then after I am going to get a tune with my SAFC which is not installed until after the injectors and pump. Please feel free to express your thoughts on this topic.

your 60's are not that great as you stated above. What plugs are you running and what gap are they? at least your mph's are close, maybe you should try building some boost off the line and letting the car go at a higher rpm

Your 60' could drop some more. Is the car sputtering under boost? How is it misfiring? Try some new plugs... that's what fixed my problems.

Damn, you beat me to it.

Practice your launch technique, that will take off a chunk in the 60 foot time.

Im running stock NGK, the gap was done by my homie's brother who is a mechanic because I dont have the tool. What do you mean my mph is close? and how would I build boost?

Its not missing, it just sounded like a stutter, but it doesn't stutter under boost.

I'd say working on launches is definitely the best (and cheapest) way to improve. If you could log your runs it would provide us with a lot more information. Make sure you're not bogging during the launch and that the 1-2 shift is nice and clean. I would drop the 60' time down before you did any more modifications. Additional power will only make learning how to launch correctly more difficult.

yha, the 14.9 run i had spun tires 0_o because of the water, the 15.1 i bogged pretty pad.

Agreed. Learn how to launch your car and cut some 1.8's, you'll see a nice drop in ET as result of that. In terms of gapping, you can get a ramp tool for a dollar at the car store or get a feeler gauge (IMO more accurate) for less than 10 dollars. Take the plugs out and measure the gap. Chances are, if they were "dropped in" or gapped incorrectly, it can stand to hurt your performance. Also do a boost leak test to see how your system is sealing.

As it has been said several times before...Change your plugs, and check for boost leaks. What RPM were you launching at? Also, next time try driving around the waterbox and tell them not to spray the box when you are pulling up.

I am launching at 4-5!? maybe close to 6 , I really am not paying attention at it. Also I am going to change the plugs again and boost leaks also. Yes that waterbox got me messed up a bit.

 

[dantingle74]

first of all with the mods and stuff u have u should be running atleast a low 14 so im gonna go ahead and say that u have a lil boost leak.

 

[TrAb]

Probably the way you are launching, i know that the first time at the track in my BPU stealth i ran a damn 15.6? After two more runs i was pulling 13.8's... I was bogging the launches at first, took me a while to get used to it.

 

[GsxEcutioner]

thanks, and sorry for the late reply

 

[chavez408]

Launching from 4k to 6k is a big difference.
Don't drive through the water pit!

I launched my 16g setup at 4750rpm and got consistent 1.70 60 ft times. Its all about engagement and how bad you want to smash 2nd gear.

Considering your trap speed is about as low as a stock GSX, I'd say you definitely have some mechanical issues.
