today was the first night out with the blower.. im launching at about 3100.. kinda feathering the clutch.. i hit rev limiter towards the finish line.. dunno if i should leave it in 4th or shift to 5th.. my last 3 runs, i shifted to 5th.. all my traps were higher, although et's were slightly worse..

id really like to try and hit 13s without slicks for now.. any ideas/suggestions would be great

hehe your worst 60ft gave u ur best time
Well you cant really do much to improve your time unless you invest in more parts. I'm sure your driving is fine so I wont even say anything about working the clutch/gas.

You'll have to take out that passenger seat too (reduce weight behind firewall = better weight transfer resulting in better 60ft)... Got stiff suspension in back? Recommend Adjustable struts unless u have the money and time to get plain jane stiff struts (non adjustatble) with drag springs... then u can just switch every nite b4 u go to track...

What are your goals? To show yourself what you can run on street setup? If so, forget what i said about the drag springs hehe unless u plan to only race in a straight line...

Invest in camber kit if not done so already... after installation, go to local shop that can adjust camber (even if u kno how, it's best to have the right equipment to measure)... after that have them check your tow... | | = Good / \ & \ / = uh oh (those pix go for tow and camber, you'll need em as perfect as possible for dragging)....

After that done 60ft should improve.... otherwise invest in drag radials (hey they're still street tires )

Edit: Yes becuz the drag radials will certainly knock off at least 2 tenths giving you your 13 sec run for sure... unless you didnt use the 16" tires u listed above (im sure those arent drag radials right hehe..)

and about what to do near end... that must be gsr tran? shifting into 5th already hehe... but yes hmm just go 4th all the way and when u near redline dont let it hit rev limiter, hit the clutch right before fuel cutoff so you can coast thru in neutral, that should help u not lose mph and keep et lower... this really depends on how far away you are from 1/4mile line when end of 4th...

Goodluck

 

Ya, my goal is to run 13s on street setup.. id really like to get there with some tinkering with the current setup if that’s possible.. i was thinking about advancing my timing to help a bit..

Suspension is really lacking.. car isnt that stiff to begin with.. aftermarket shocks are probably next on my list..

Im actually usually the LS tranny.. i know many ppl find that weird b/c of the long gearing.. one guy I know actually said I hit rev limiter after I cross the finish line but its a fairly close call.. ill keep it in mind to kick it outta gear before hitting the limiter..

Thanks for your help

 

Hey man howz it goin. When you said you hit your rev limiter I thought you hit it earlier thats why I said shift into fifth. Those times look good, to bad your rev limiter didn't go a little higher. I'm SURE with a better suspension set up and better tires you'll be in the 13's no problem.Take it easy.

Something is extremely wrong how in earth are you hitting the revlimiter in 4th gear at 94mph on a ls tranny..

What do you rev out to??

 

Keep into consideration that he will hit rev limiter at 6500 on an ls motor.

 

very true.. redline for the ls is really low..
and with the sc, the first couple gears, redline comes super fast

 

is this the m45 or the m62 jrsc?

 

M45

 

You can do it wo=ith those 60 foots but not that ET&gt; Get the smaller blower pulley and go 13s. That 45 wont like it much though on the street if you drive a lot in hot weather.

 

if you got some smaller lighter rims with sticky tires you'd be in the 13s with ease,
with my gear ratio i am also at the very end of 4th gear by the end of the track and was having to shift into 5th at times, when i went with a slightly taller tire i was able to stay in 4th and thus ran better times, 5th gear is hard to shift fast and seems to cost a tenth if you have to,

so the decision you have to make is whether to get slightly taller tires which will keep you from shifting into fifth or get smaller lighter rims but then you will have to go into fifth.....either way should help you shave off a few tenths

 

i dont know if everyone is gonna agree but from what i was told by other peaple and have expirenced is that a light fly wheel will actually slow u down a lil in drag racing instead of making u quicker it will alow your revs to come up and stay up and could be the reason u had to go to 5th.another thing they said if your turbod sc or nos on street tires the stock fly wheel will help out being heavier off the line it will bog a lil helping to leave better this is what i was told dont take my word for it

a couple ppl mentioned possibly going to 17" rims, but id rather not mess around with the rubber as my 60fts are pretty good so far..

the ls 5th gear is so long.. im sure some ppl could shift two gears by the time i throw it into 5th

 

everything looks pretty good but traps are fairly low. id buy a CRV crank pulley and underdrive that charger for 2psi more boost.

 

any1 think a beefyer clutch would break him into the 13s?

I think it would break more axles then 13s. The 60 foot time looks decent, its the MPH I am worried about, either the car is heavy or has too much drag or both. Top end is the main issue here not launch.

Thats what Im wondering too. My 94LS revs to 7200rpm, and I hit rev limit as im passing finish line at 1/4 mile. Im confused???

Do some headwork, and extend the redline. You'll be in the 13's for sure.... I found from my experience that the JRSC loves a higher redline.

Are you running slicks now or were those runs on street tires?

 

I agree with TurboChrgd_Civic.
Some headwork (the jrsc loves big, clean exhaust ports), a larger TB, and some tuning, and 13's are no problem.

I don't recommend changing the static timing, as the jrsc system will knock in some areas, and not in others. If you're serious about performance, go with a Hondata system and tune timing based on load and rpm on a dyno. Same goes with the fuel.

Another option that may take you into the 13's is to run a slick, or Drag radial. A slick or Drag tire should allow you to kick off the line quicker, although your 60' time isn't too bad to start with. Combine this with a bit more weight removal, and you'll see a 13 second timeslip.

FYI, going from 14's to 13's was tougher than going from 16's to the 14's. It's going to take a combination of great driving, with either more power, or better traction.

its on street tires.. fm901s @ 20psi
hoping to hit 13s without slicks first.. then just work from there.. with slicks, ill probably need to pick up some spare axles hahah

im not sure if my motor can withstand that higher redline

 

The motor will handle a bit more rpm before it blows up. For the most part the B18 bottom end can spin well, it just doesn't make power in stock form over 6800 rpm. If you're blowing air, you should be able to get to 7200 while still making good power, which should allow you to finish without hitting the rev limiter.

We have spun LS/VTECs to 7800+ rpm in relatively stock form with no issues.

 

You are about as fast as your mph is going to get you to go without a PERFECT run. Personally, I'd think you're due for some tuning. 40psi on a blown motor seems like you might be running lean. Go get that thing on a dyno. At the very least you can see if you are leaning out like crazy top end.

Slicks will definetly get that 60ft. down, and a better 1/4 mile!
