Well what can I say, I Know!
. I cant drive, lol
![]() Heres my best crack, with half a tank in street trim, but with sticky street/drag tyres. ET 13.22 Speed 104 mph (best for the night was 107mph) R/T -.038 60 2.034 (this is my best ever) 330 5.628 660 8.568 660 speed 134.25km/h 1000 11.096 Ambient track temp, 24.0c Humidity 68% Density Alt: 1766 feet Wind 9 knot headwind Track temp 36.2c No excuses for not hitting a 12.99, but no other 12.9 car did any better than a 13.2. I reckon if I can take .1 off my 60 then I will have it. I did learn a lot, and had fun doing it. And I do believe I will make it with a bit more practice. I was not realy happy with any launch last night. Those 4.11 diffs certainly keep you busy on take of. First run all wheelspin and rev limit cut of in first and second, lol Maybe cooler weather will do it for me, what do you think guys? John

Just to pass on some info this has nothing to do with your car but with mine when I ran the 12.90 @110 all the car had was bolt ons at that stage I had no 4.1 or convertor yet. But it did take me a few goes to get it right. No doubt it will come in your case better sooner then later , But it might be time for some DiFillipo's... :evil3: Great effort..

As a matter of fact, I am going to play a bit with difillipo headers very soon. I think I have convinced myself they will improve things a little over the paceys. I have no doubt I will make the 12's soon. I just have to do everything right.
And gone are my days of thinking that drag racing was easy. You do have to know how to drive, even without corners ![]()

Di Filippo's or anything else won't matter superpursuit, you are making the power going by your signature and a recent dyno sheet that you posted. 107-109 MPH will see you into club 12 but you need to stop that tyre spin on the launch.
What tyre pressures were you running in those tyres? The best my ute would get down the track with M/T street radials in FULL street trim was 13.14 (that was with a passenger), and it was very difficult to get it out of the hole. When i fitted slicks and front runners in FULL street trim at heathcote i went down to 12.58 and at WSID it went 12.49 all with mid 1.7 60ft times. Call me if you like for a chat about set up or driving technique if you like. Cheers Craig |

Thanks Craig, I did have a lot of probs with wheel spin. I am going to go and buy my own tyres now. (Because I am addicted) I will call you one day. and if your ever over here I will throw you the keys. (Did you drive Wade's ute?)
With the Difillipo thing, its just a bit of R&D really, for my own curiosity.

I drove Wade's car on the street for a week after we raced it. Chris drove the car on the racetrack, he's 23kg lighter than me and we were chasing the record for the first manual XR8 11 second deal. I'll be bringing mine back out shortly for a crack at "club 11" with "oil pump gears opened engine". Would love a drive especially at Kwinana that place is killer....... Cheers Craig |

Mate wheelspin in a manual and where you change gears "will affect" your mph I have seen many a manual with one driver than another better driver same car next pass put 3mph+ on its trap speed. Thats the thing with manuals 1. you have to get the launch right 2. you have to (through trial and error) change gears at the right revs in every gear, this can affect mph and if you get alot of wheelspin in 1st can also affect mph, 2-3rd wheelspin wont affect mph as much as the car already has its momentum therfor getting fairly good acceleration. What rev were you leaving the line at and what tyres were you using and what was your tyre pressures. Also that RA 1766ft you would gain about 1.5 tenths with good air at say 500ft. Mate with good rubber and with 4:1's and a good launch should get you around a say 1.85 or better 60ft which would knock about 3 tenths off your ET. |

Had 8 runs, launched the best at 4500rpm with the MT ET Streets, 275/40R at 18psi.
I do have to work on where I change gear, I think I was holding the gear a bit too long and getting out of my torque range. I sort of have the theory right, just have to practice more. A run of 13.55 saw 107mph. Did I mention I had fun ![]()

Next time out start at about 3500rpm and each pass after give it 100rpm to see where your tyre threshold is, if you go the other way and get wheelspin you will be lost as to where the best revs are to launch. Tyre pressure seems ok, when I had MT streest 255/50/16 I found best tyre pressure was at about 16psi. Oh and John fun is a understatment lol. |

Chris (Bluepower) is here at the moment, just dropped off my baby (yay)
He mentioned that a 275 tyre will take at least 20rwkw more than a 255 to turn after half track. This could also affect mph. |

after being in a few manuals with 4.10s/4.11 gears
i dunno if im a big fan (in manuals) could it be possible that the time spent off full throttle and back on and maybe that extra gear change in the space of the 1/4mile, could help cancel out the gain to be had by having shorter gears.... with the superpursuits time not neccesarliy dropping just made me wonder... after being in a couple of manuals with very short gears just seems(seems) slightly taller gears and letting the torque pull you through is the better way to considering these cars unopened dont rev a whole lot... have you tried changing as late as possible on your 1-2 and 2-3 shift and maybe a little later on your 3-4 4-5 just askin and throughing a few thoughts out there as it seems this car has the potential to be doing mid/high 12s on proper street tyres |

I am still in fourth, with the shift alert (still at factory setting) going off about 30m before the line. No extra gear changes.
I still think its an experience thing ![]()

I just got of the phone to Simon (Xtreme Ford). He called me all worried, and you can hear the dissapointment in his voice.
Simon, its all good mate. You have given me a weapon and now I just have to learn to use it. We will get it there buddy, cheer up. ;) Did I mention how much fun I had ![]()

Sound like you had fun Superpursuit.....LOL......
One of the best things i observed when watching the LS1 guys at last years LS1 nationals was all the quickest ones were manuals and all were in 4th gear just after half track. There gearbox ratios are different to ours (so i'm told) and being so much lighter than our cars they are not moving so much weight down through there. It takes a bit of practise to get a combo that works for you, have a pen in your car and write on the timeslip things like RPM shift points, tyre pressures etc etc on the run. Put then onto a spread sheet when you get home. Watch other cars, it's a learning process when it's all new. And have some fun to..... |

It's not always the case. MPH is a great indicator for how much power a car has but to give you another example my old 3v in race trim (weight removed) would run 109 MPH with only 235 RWKw's. My ute in FULL street trim with 251 RWKW's ran 107 MPH - in race trim 114.50 MPH. So weight is also a factor.
Another example: Wade's (Quadcams) XR8 ute at calder 300+ RWKW's in race trim 12.2 @ 108 MPH, 2 days later at heathcote with identical set-up 11.87 @ 118 MPH. Track and weather conditions also play apart and the real key to good ET and MPH is getting out of the hole with no tyre spin to give these heavy cars some momentum going forward. Don't forget a BA XR8 ute weight with driver around 1900kg's or in race trim around 1725kg's, that's damn heavy compared to our LS1 friends. Time to maybe slot my engine/gearbox into the funny car (1000kgs approx) and give it a whirl....... |

Its all in your 60', you just have to be very un sympathetic like Kev to get you 60' down. He is slamming it into 2nd while the front end is nearly off the ground. Not my kind of punishment, but thats the way to get quick times in the manuals....Craig will also confirm this !!

On ET streets you shouldnt have to many dramas with your driveline but with slicks be prepared to break things especially in a manual. |
