3) What I did at the track

As you can tell, I couldn't hook worth a shyt outta the hole.

Vehicle was uncapped from the cutouts running 92 octane with NX RACE Fuel Additive and fresh TR6 plugs.
Step-by-step on what I did on my run:

1) Drove through the water pit
(probably should have driven around it and reversed into the edge of it)
2) Put it in 2nd, compressed the brake and did my burnout for 5-7 seconds
(i know, install a line lock to save my rear pads/rotors)
3) Put it into 3rd gear and drive up to the starting line.
(in 3rd i personally got better results than in Drive)
4) Prestage lights, rev up to 2700rpm right before the tires begin to spin
5) Tree lights go down, mash the throttle and away we go spinning tires.

I'm happy that I improved with every run in every aspect....but I'm unhappy with my 60' times as they should be closer to 1.65 or so i figured. Any ideas on what i could have done or could do to achieve that goal in my 60' with my current setup of mods?

I did install the TR6 Plugs before this run as I was planning to run nitrous but chose not to since I can't even hook up properly. I think i need to spend A LOT more time working on that then adding more power. Could the TR6 plugs have hurt my performance as well versus using the TR55?

sounds like you just need some seat time and learn to pedal the car untill it hooks. you have what it needs. no reason that car doesnt go 1.7 or better 60'

where the f do you get more than 4 runs ?

I would stay at 16-18 psi on those tires. What were the track conditions?

Kaleopapa

Big Island of Hawaii, it was a Saturday Night Outlaw drags.... not a sanctioned event. So as long as it doesn't rain, you can keep going back in line and down the track over and over again. The track is never prepped well for the Outlaw drags. They only prep for IHRA events and "Test-n-Tune" weekend.

I would try to leave off an idle or close to it, sometimes stalling it up that high hurts way more then helps.

Kaleopapa

KP: i tried that on run number 5.

1) 14.193 2.635 60' 25psi in D/Rs
2) 13.576 2.534 60' 25psi in D/Rs
3) 13.297 2.354 60' 20psi in D/Rs
4) 13.183 2.288 60' 20psi in D/Rs
5) 13.082 2.284 60' 20psi in D/Rs
6) 12.995 2.243 60' 18psi in D/Rs
7) 12.891 2.174 60' 15psi in D/Rs
8) 12.781 2.122 60' 15psi in D/Rs

It did help a little. however runs 6,7, and 8 were done by stalling it up. i shall try launching just above idle next time as well. thanks for your reply.

If it spins the tires its really hard to do anything. I have ran very low 11s on 16" ET streets so the tires are decent. Just need to get them to hook, how much air in them?

Whats the elevation there? if its anywhere near sea level you should have an easy 11 second car..

Kaleopapa

KP: Big Island Drag Strip is luckily at sea level. The tires had 15psi in them on my best run.

1) 14.193 2.635 60' 25psi in D/Rs
2) 13.576 2.534 60' 25psi in D/Rs
3) 13.297 2.354 60' 20psi in D/Rs
4) 13.183 2.288 60' 20psi in D/Rs
5) 13.082 2.284 60' 20psi in D/Rs
6) 12.995 2.243 60' 18psi in D/Rs
7) 12.891 2.174 60' 15psi in D/Rs
8) 12.781 2.122 60' 15psi in D/Rs

Burnout is WAY too long. Try 3 to 4 seconds max!

Also, play with start line rpms...maybe try 1800, then 2200, then 2400, etc.

Kaleopapa

every run i did, i did a longer burnout and my times were getting better.
1st run, no burnout
2nd run, 2 sec burnout
3rd run, 3 sec burnout
4th run, 5 sec burnout
5th run, 5 sec burnout
6th run, 6 sec burnout
7th run, 7 sec burnout
8th run, 10 sec burnout

but thank you for your reply. i will try adjusting my launch rpms to see which works best for me application.

deejaydaze

iTrader: (11)

Yeah i didn't notice your long burnouts. I'm with DO. 4 seconds max. Those M/T drag radials don't like long burnouts IMO.

How many days does it actually rain on the big island?

Come over to Florida for a bit....


You also dropped PSI!

aram

iTrader: (7)

Those 60fts are so terrible that burnout time or tire psi doesn't really tell you anything.

deejaydaze

iTrader: (11)

good point

bad track conditions?

Kaleopapa

it rains ALL the time...... sometimes even when its hot and sunny! hows that!

aram: "those 60fts are so terrible" thanks for restating the reason for me posting this thread. I am looking for CONTRUCTIVE HELP.

and yes deejaydaze, after looking at many peoples timeslips for the night, everyone had bad 60fts. an example is a guys 2002 Z06 Corvette that consistantly does 1.7 60fts, was averaging 2.5s all night.

deejaydaze

iTrader: (11)

Woah I didn't know it rained that much. I went to Maui for 3.5 weeks and it was sweet. I was told it rains 2 days a year or something.

I know your pissed about the 60 ft, but I dont think aram was being a dick to you.

With all those runs did you get to talk to others besides Mr. Z06?

The only thing that sticks out in my mind is your fuel system...you list 28 lb/hr injectors, and no fuel pump. I'll assume that means you have the stock pump.

The one problem I've found with mine (I log my fuel pressure, AFR, and injector duty cycle with my tuning software) is that the fuel pump likes to drop pressure at WOT as the RPMs climb. This isn't an isolated case, as others have had this problem as well...it is most likely inherent to the design of the system (no return/regulator at the rails).

Due to this, I've seen injector duty cycles as high as 91-93% on my bolt-on only, untouched LS1 (no cam/heads), and that's with the stock 28.8 lb/hr injectors. I had to step up to 34.6 lb/hr injectors just to get my duty cycle down to about 75%, but the pressure still drops.

If you have a way of verifying your AFR, I'd do it and see where you stand. I'm thinking you might not be getting enough fuel for that setup. The stock system could barely keep up with mine, and I'm not nearly as modded. It never got to the point of not being able to get my commanded AFR at WOT, but it was enough to make me nervous...I'm still considering a complete revamp of the fuel system on my car.

Kaleopapa

i'm not pissed, i'm disappointed. I didn't think he was being a dick.... just stating the obvious.

and yah, i talked to about a dozen guys who were all complaining how the track wasnt prepped. as they tend to do that for OUTLAW drags here. only sanctioned IHRA events and SOME test and tune days do they prep it well.

my older sister and her husband live on Maui and it rains more than 2 days a year, however there are a few places on the island that rarely see rain. on the Big Island it rains A LOT. .. . . on the Dragstrip side of the island.

Kaleopapa

Meentss02 yes, stock fuel pump. Texas Speed told me that there's a slight difference between the '98 fuel pump and 99-02 versions making it slightly better.... HOWEVER, my injector duty cycle is at 96-97% at WOT. so yes, i really should buy some 42lb injectors and probably put an inline walbro 255lph.

btw: sexy wheels SP500's are beautiful

MeentSS02

iTrader: (11)

Thanks...yeah, I'm not familiar with the 98 fuel systems...my knowledge is limited to knowing that they used a metal tank and filler neck that is a PITA to drop. I'd recommend the new injectors, but I'm thinking the vast majority of your gains will come from more experience and better track conditions. I've had my fair share of high 13 second time slips with mine...it happens.

Kaleopapa

yah, this was my first attempt with this car.... it'll get better i'm sure. after the injectors and pump, and a lot of seat time, i'll probably do a nx plate 100 shot of nitrous. but not untill i get it to hookup properly
