How come lots of threads here get pumped full of useless info???
Ok ok Anthony put this in the wrong section, i chastised him about that last night while he was around, but seriously guys, cummon!!
Howard and GTR-XU1 are the only people who have really been of use, Beergut and Andy have been usefull as well. Craigs comment was pretty funny.
The owner of the car is a die hard manual fan, but this car is simply not streetable with a manual. Way to much HP, solid center button clutch, its an animal. Doable, but not really enjoyable.
We decided a manualized auto would be the best option, i dont know where people got the slush box idea from. A manualized auto will give the car a lot more streetability, which is the main thing we are chasing here.
Heath, sorry mate, your comments in this thread are totally useless, i know you have never had or driven a vehicle like this, and it shows. In this situation the only place a manual would be better would be on the race track, and to get this car on the track would need a lot of dollars spent in a lot of other places, something the owner can not do at this point. Also im guessing you still havnt driven a properly built manualized auto? If not i suggest you do. Will open your eyes.
And no, its not the diff. Basically we put the fully rebuilt box into the car when we rebulit the engine, then drove it about 500km on the highway, at light throttle. This basically destroyed the box. Since then the owner has taken it to the drags and babied it and it is still in there, just. Over all it has done less than 1000km behind this engine, being driven carefully 99% of the time, and is about to fall to bits.
Andy: the HP and torque figures arent that far off. You have #@$^%& your calculations up, royally. The OP didnt state at what RPM those figures were taken. For some stupid reason you have assumed 6000. This is incorrect. In actual fact when the car was on the dyno at a very reputable shop being tuned it fried the Exceedy sports tough clutch and blew both head gaskets at around 4200rpm. This has since been replaced with a solid sprung center puck clutch, MLS head gaskets and ARP studs.
Also with your Moroso inspired calculations you have #@$^%& up there to. Firstly i have never seen a V8 Torana sedan with a full interior, extra 50kg of blower and intercooler etc, a driver and half a tank of fuel pull in at 2900lb. 3000lb is closer to the money and still on the light optimistic side.
Secondly for the Moroso style calculations to be correct you have to be at full throttle with the engine developing maximum power for the entire quarter mile pass. This was not the case, the car spun the tyres furiously in first, second, got a bit of grip but still very crossed up in third and gave a bit of a wiggle from the back end in fourth, basically it spun the tyres and the owner was on and off the throttle for 3/4 track, hardly going over half throttle for the first 1/2 track.
You seem to do that a lot, your contributions to the forum and your knowledge are great, but perhaps you shouldent run head first into a situation??? Honestly your first few posts really shat me off, you have taken incorrect figures, done some fancy maths with them and tried to make yourself look cool and insult the OP at the same time. Fail.
All the OP is trying to do is find a box that will survive, if he stated that the engine only makes 600ft/lb's and you recommended a box to suit i dont think it would last long, do you?
BACK ON TOPIC
At the moment were looking at importing something like
THISThats just the first one i found and will look at others, but i think TCI is farily good. Has anyone had any experience with this gear or anything USEFULL to add to the thread.
Oh yeah, Howard, he really wants one of those Jerico's, and we were in discussion about that last night as well
.
Cheers.
