I top out 3rd gear right at the end of the 1/4 mile, anyone think i'd be better off shifting into 4th around 6750 or should i keep ridding out 3rd to about 7200?

you might want to think about telling everyone what youre racing and what mods you have.

ok, sorry i didn't before, I have a 86 NA with no cats an rb catback with a 2.5 inch pipe where the cats were, and a cone filter with my aux ports tapped into the air pump. my best run was 15.277 @89.10 mph with a 2.136 60ft. And just started theTB mod

Dont shift into 4th. Just stay in 3rd, it will save you alittle time.

I agree, just stay in third, you may run into redline a little but its faster than taking the time to shift.

Yes, just ride out 3rd. While it may be out of your powerband slightly, it will still be much faster than shifting to 4th.

K thanks guys although i hope i need fourth soon i just did the tb mod and ported it, as well as ported the exhasut manifold, and added a posi and got 225 tires to replace trhe bald 205s i have my 15.2 on

my tii before the new turbo and 8:1 a/f after 4k was running a 14.1 at 96 if i kept it in 3rd and a 14.2 at 101 if i went into 4th....

i thought about that for a while and decided the answer was to get a bigger turbo and a safc. Now hopefully when i go back to the track ill be going fast enough to have to shift into 4th... and run a respectable time too.

That is the new answer to all questions ever. NA/TII it doesn't matter this is the answet to your problems

Umm, 8:1? Is that a guess? No lambda unit reads that low, so I don't know how you can accurately claim to have that number (let alone have the car run)

Jaared

yea its a guess.... the dyno sheet is posted. ill find a link in one sec. i have 680s in as sceondaries and nothing to tune with. silly me. at 4k the a/f goes right off the bottom of the chart. yes the chart ends at 10a/f.

Jesus... did it bog down running like that?
Wideband O2 sensors can only read down to 10.... you maxed the thing out!

3rd gear suckd... explains my 1/4 mile times. made my clothes smell of exhaust and tailgaters fall asleep at the wheel.

new turbo is in, fmic and safc are in the works.... i read the 1300cc.com nos setup guide thing you did and i am thinking of running about a 50 shot.... but thats another thread. when i get there i might ask for your opinion on my projected setup. ill paypal you a dollar!
