sr20 1/4 time

[hungryjoseph]

i'm just curious... can i run mid 12's on the 1/4 mile with 15psi? (s14 sr on a 89 s13) with a garet turbo manifold, front mount, bov, and 3inch turboback? if not then what else can i do bolt-on wise?

[boost_creep]

t25 or t28?

low 13s is very possible with a t25,so id say high 12s is possible with the t28.

[hungryjoseph]

its a t28. what can i do to get that extra .5 in? greddy inake manifold help that much?

[Rosco]

Get some TIRES......You can't beat traction..

[hungryjoseph]

haha anything else i can do besides tires? motor-wise sorry forgot to mention that

[adrianfromthecastle]

dont fill the tank to full

pulleys, lighter flywheel, drive shaft.

[wa-chiss]

make it so the only thing in the car is the driver seat, dash, and center console.

LSD, weight reduction (smaller battery, gas tank, YOU), some slicks, smaller pulleys, aluminum driveshaft, racing fuel. Practice on ur 1/4 mile .

haha. Yep that helps

I dont think you can predict 1/4 time with engine mods. Tires are realy important. When i went to the track the first time i did was 16.7 because i lost traction the next time i did a 16.1. (stoke ka)

[hungryjoseph]

ohhhhhhh... i have an aluminam driveshaft and lightened flywheel, but i never really payed attention to tires all that much...

let me know how that works out, I have a very similar setup (S14SR20DET powered S13 hatch). I'm running 13lbs of boost, putting down ~260hp to the wheels.

I did all the underdrive pulley's, S14 FMIC, S15 T28, greddy dump, 3inch all the way back exhaust, exedy stage 2 puck clutch..etc mods.

I have VLSD and 255 Toyo T1-R's keeping that to the ground in the rear.

Ive only been to the 1/4 mile track to watch, once I saw a redtop S13 do low 13's on 17lbs of boost (but his starts were slow).

[hungryjoseph]

right now, i AM a ****ty driver, but all this gives me something to look foward to when i CAN drive stick well...

[hungryjoseph]

since ur running around the same, if u ever go let me know how u do... i probably wont be at the 1/4 till spring break or so.... i need to get the car running again... might need a new long block cus the tip of the spark plug fel into the cylander... i dotn know if theres any piston damage but all the labor costs to chek that and get a new headgasket or w/e... might as well get a long block

Alright,

A friend of mine has a Redtop SR20 with FMIC, 550cc injectors, T28 GTI-R turbo, 14psi, and ran a 11.9 1/4 on drag radials, and a 12.3 on street tires..

[hungryjoseph]

wow... nice... s13? stripped?

Damn that's hella fast.

[hungryjoseph]

sigh... i'll dream of that... or dream of a running car... which one to dream of first? LOL

[hungryjoseph]

seems like im always dreaming with this car

I had that same problem; notice the plug on the right in this picture.

Honestly though, I don't think it did any damage. I knew the second it happend because the car ran like complete garbage as soon as it would reach boost, but after I swapped out plugs it ran fine.

[hungryjoseph]

omg.... you shine light into my world.... that plug looks EXACTLY like mine... i need a new hadgasket too.. but wut could cause the tip to fall of like that

Faulty spark plug or u driving the crap out of ur car

and by driving the crap out of the car he means knock.

15psi with T28. First off is making reliable power. 480 or 550 injectors, Z32 MAF and ECU tune. 256 or 264 cams will help. As for running 12's. Youll need some drag radials or slicks to achieve a 1.6-1.8 60ft. Its not too hard with practice.
