Apart from drag radials what am I doing wrong!!!!
 
Manual, 1400kgs and 500rwkw and I cant get it to 60 foot. runs low 11's@138mph all day :(

138mph ! You should see high 9's low 10's

Hey Dazz. Whats your car weigh? Just curious

Tell me about it!!!!! and to think it still has standard head studs so lowish boost in it as well. Could put an easy 10psi more in it if i got my ass into gear and changed them over. They are in the cupboard waiting for me to do them. Would probably make close to 600rwkw and run closer to 150mph then  

 

I wonder how many people have been booted from Sydney Dragway for needing a chute before a cage!!!!

[ido09s]

It all depends on the set up.

 

The car runs a close ratio OS Giken 5 speed gear set and 4.9's in the diff so its always in the sweet spot. Its got the power and the mph is there, I just cant get the damn thing to 60 foot. I have an easy half a second in the 60 foot alone if I can get the car to work

 

The BOV works well and yes it does have one. I hate turbo chatter. Anyone with half a brain knows chatter isn't the best thing for a turbo car.

 

It has a 2 step for launch and I am pretty sure the computer has the anti lag option there but there is no need for it.

I was always told one tenth gain in the 60ft equals four tenths in the top end. My experience has shown this so I tend to believe it. But every case is different. Brad whats your half track ET and MPH?

[ido09s]

4/10's would be VERY nice!!!! would mean I am well and truly into the mid 9's

 

I would need to check the slips as I haven't raced the car in quite some time. I hate street meets and Sydney Dragway rarely run ANDRA TNT's anymore :( I am hoping to get it back out as soon as the weather starts to cool off though.

Standard engines/valve spring and a 5000 stall???
I think not!

 

Yep,4500-5000 stally with springs done,

 

Guys were doing it nearly a decade ago,bolt on mods was competitive unofficial thing back then.

On old ls1 forum Cop,markone,Dogsballs(Dale) few others were doing it with auto..couple guys did with manuals planb & phonsy.

Those were just well known guys.

 

Best we could do was low 12's full weight cars but auto's were dying & slipping like crazy after awhile.

I did suspension & few things on customer's ls1 crappy cam/tune hq kingswood years back...went from 12.4 with 4l60e down to 11.8 just with th400-3500 stally & 6scyl sispension changes...had more but got sold...it was bomb of a car.

[gtrboyy]

5.7 litre Boltons only unopened engine,springs,extractor/otr basically...couple of very fastest guys cheated blueprinting engines & shaving heads lol

 

Like said in first post it's crude but gets job done..crude being not nicest thing to drive...comes down to want to run good time or want good drivability.

 

Dont forget when it was done decade ago cars/engines were near new,tuned ragged & blokes were willing to break them to get a timecard..lots of dead driveshafts,auto & diffs died to run 11's lol.

 

2 different things to do it.

 

The 6.0 was even better blokes going easy 11's just cam or good recipe of e85.ls2 cam,shaved heads & piston valve reliefs ground into pistons big stally & short gears.

Either ran a good time or auto blew up lol.

 

 

I know most peeps go race shake head wtf happened should be an 11 or 10...they run 12 or evem 13's.

Times are there just got to experiment/risk breaking parts.Several workshop cars done all this  way before all of us years ago.

I am not 100% sure here- I have observed for every .10 saved on 60 foot, generally equates to .15 to .20 in the ET. Never seen more than .20 gain for .10 60 all things being equal.

 

I could be wrong though, different setups may do different things. In fact, I remember reading somewhere that on average, turbo cars gained less on the ET per avergage gain in 60 foot than NA cars though, and again from memory, .15 gain in et for every .10 was expected for turbo cars (actually this could have been turbo all wheel drive cars) and .20 for every .10 for NA cars. 

 

I am far, far from any expert though, and only have very limited drag racing experience, only spouting what I have observed through my own time slips and others as well as what I heave read/ heard...

Great thread and chatter fellas. Really interesting reading and ZERO dick stroking. Thanks!
I've never weighed the taxi....I guess I should.
I haven't got the coin to change gears/wheels right now so will just bank this info until later on.

Umfortunatley there is one member that will be stroking his possum cos thats his thing....

He just cant comment in here cos he runs a 6 so these 1/4 mile times are his 60ft

[IMORAL]

Correct. He dosent have a possum. But then........

I could only find a handful of time slips but the one i did find that was decent was per the below

 

60 - 1.966

half track - 7.654

mph - 98

et - 11.445

mph - 134.5
