does this setup has a chance to do mid 9sec. using t67 and b16 tranny in 95 civic h.b. 1900lb. dynoed in 3rd and at 6-7K it made 360whp-470whp(something like that...close enough..hehe). then at 9500 it made it's peak power 550whp. Remember this was a 3rd gear pull on a 00 b16a tranny. Motor GSR 1.8L@25psi.

What are your guy's thoughts???

If the car is shifted at 9.8-10k rpms from 2nd to 3rd what rpms will it fall too??? Any clues guys???

what about from 3rd to 4th gear...any clues????

I know at 9.8-10K rpms in the b16a tranny in 4th gear with 26" slicks the car hit a topspeed of 150mph.

any comments will be appreciate!!!

anyone please

 

well it seems you have the power but is your suspension set up right, there to many possibilities. if ever thing is perfect and dialed in yes you should hit 9's.
trany wise you did not give enough info to determine the shift drop off points.

 

i think your RPM's will go to 4000 to 4500 in your gear shifts. if your power is constant and suspension is correct, where weight transfer doesn't effect traction,it is very possible. oh yeah and dyno horsepower is nothing because most dyno's are off anyways.1

 

that is the same power level that I am at right now. I have been breaking some driveline parts the last few times that Ive been out, so I dont have any difinitive answers for you.
but I can tell you that after making a few passes we sat and calculated the "potential" run if everything went well, and we came up with a 10.38 @ 140....
Now keeping in mind that these are just calculations based on a few partial runs, taking the best portions of them and compiling in into an average run.
Having said that, I think that a high 9 is possible if everything goes well, but I intend to re tune the car to get some more power out of it so that I can ensure a 9 sec pass...

I dont know if this helps you any, but I though that I would share my experience since we are talking about such similar setups...

 

In general with around that power level we normally do not run 26" slicks, a straight GSR tranny and 25's has always worked well for us in the past. But as you are using a B16 tranny, in order to keep your mph up it may be wise to go with 26's. It really just depends how high you'll be trapping, etc. I have played with this gearing in the past so I have the drop calculated. Assuming also that you can get your ground speed up (traction/weight of the car), shifting at 10K each gear: 1st-2nd will drop you to ~6500rpm, 2nd-3rd ~6900rpm, and 3rd-4th ~7500rpm. Just my $0.02, good luck

 

i know chuck from alternative motorsports,runs 26x10 slicks,in his hatch and his best et so far is 8.90.......that et should get better this weekend @ nopi cordova....good luck chuck....

 

is this car on wheelie bars? is it a street car? what you got for suspension and can the driver even drive?

 

Hey guys thanks for your inputs. Greatly appreciated. We just came back from the track and here are the results... KIND OF SUCKS!!!

btw car is dragged-out.. not streetable...stock rear control arms, sk2 coilover, AGX struts, couple of poly bushings in the strut to stiffen it up...Front suspension is nearly the same too. No HIGH TECH stuff yet.... and yes we have the traction bar up front. Clutch is Xtreme 4puck....

Results: 26x9 Hoosiers at 13psi in 1st was all slipping and wheel hopping. 2nd was the same.....I hit the rev limiter at 9.8K rpms a few times in both gears to bring up ground speed. In 3rd just a slight lag and then 2-3 seconds I'm at almost 10K, but car is like swaying left right left right...<---scary **** guys... then I try getting into 4th...and rpms starting climbing fast, but swaying got very very bad.. so i quit....

Help me 8 and 9 secs guys....even 10sec help...shoot!!! with smaller turbo and 25" slicks we did 10.5s no problem...

Our main goal is 9sec...

Here is what I have to ask you veterns...
1) What is causing the swaying when 500+whp kicks in on the top end???
2) Will the straight axle rear combination kit in the back help at all???
3) Will front racing hub brake combination help...straighten up things.
4) please help as we are stressing about this issue...

thx so much

 

kataku: what's the best GZ has run??? any pixs time slips to show me and dyno graphs...

The turbo we have makes big lag on bottom end.. any dyno graphs will help me alot on this issue too....but really the suspension issue is more important...dont wanna go sideways...

 

try dropping the tire pressure and make sure it is even(around 5psi). invest in a good tire pressure guage!! maybe even a little more toe in.

 

You say the car is pulling left to right? Are you sure it is not pulling in one direction and you are pulling it the other direction by over correcting? What diff are you running? Sounds as though you may want to stiffen up the suspension and steering components in the front.

 

no... i had had the problem where it pulls to the right and i readjust... now it just wiggles left right left right on the top end...

so it is best to lower the 26x9 right??? about 5psi??? i ran the 25x9 @ 4-5psi and it worked great. i thought that taller slicks would require more air....guess i'm wrong.

btw we are using a welded diff...

thx again for the input...

 

I say not yet.. your graph sounds too peaky.. its important gear/tire your car correctly to your powerband.. i noticed the turbo cars that rip are the ones that make good power in the midrange and has a smooth graph all the way to redline. not like going from low and jumping up really high.. you will know if your car isnt setup right and you go to make a shift and the car bogs then breaks loose again.. hope this helps.

 

1900 lbs with wheelie bars and 550 to the wheels will break 9.99, but its not going to be easy. especially with a gsr crank. serious suspension knowledge, traction, and track/air conditions will be in play. honestly, you should try the 25x8.7's.

why do you say its tuff w/ a gsr crank? because it's going to have less torque area? Laskey was over 2000lbs all last season and there were days he came out on 550whp and still ran 9's no problem. If the car is set up to hook it should be doing at least high 1.4's w/ wheelie bars on 26" slicks. If your not doing that much something is wrong.

 

if the car is swerving after ever shift into gear, your probably jerking it yourself. I was taught to plant left steering arm/elbow into window net or door to guarantee one hand is planted staight. it used to happen with me.Hoosier tires are probably not hooking and I hope the wheel hop is not from a Z10 like mines. we put our tire pressure when on 26" at 6 minimum, we notice car bounces a lot at top end when too low.just my experiences.

because the powerband will leave something to be desired.

because his car was dialed in already. he had time in it already and he had knowledgable people helping him.

obviously.

 

i only said it wouldn't be easy. i never said it hasn't been done or will continue to be done in the future.

 

i think hitting 1.4 on a regular uncut chassis isn't that easy, i have many timeslips to prove. track conditions make that difficult.

i agree. but if the car is set up and dialed in and your running a NHRA prepped track, you should be in the high 1.4's.

 

What crank would you recommend Jinxproof? I haven't heard this before. What would you choose instead?

Thanks

 

most likely he's talking about a LS & b20 crank to move the power band little more down in rpms and make more tq

why does the chassis have to be cut? I know of 3 cars off the top of my head running Pro4 Nopi all able to cut 1.4's w/ 26" slicks and wheelie bars. Im not saying 1.4's are easy but that should be your goal on 26" slicks.. Alternative motorsports has even done a 1.3 on 26's.

Yeh but I don't think its a problem though when you rev the gsr crank to where it needs to be revved. problem is most people don't.

One of those cars I mentioned above is not experienced like Laskey and had less then 10 passes on the 26" slicks before they started hitting mid 1.4's consistant. And this was w/ the rear suspension even set up wrong for wheelie bars.
