trans has been together and havent noticed any issues over over a year, dont run the car on motor much but i believe its somthing like this

1.75
7.6@92
11.6@115

first stage is a nozzel 78/48 comming on a 1000/wot
second stage fogger 28/20 comming on at 1500/wot

 

Over a 2 second reduction in ET with a 346 CI and nitrous is very impressive.

When you look at the fact your NA MPH in the 1/4 mile is now the MPH your car is running in the 1/8 mile on nitrous, the car is working pretty good!

I hope the change in gear allows the car to build more MPH on the back half with no loss in ET.

? what does backhalf mean?

 

3600lb car, 26mph backhalf on a 78N jet.

the MPH difference between your 1/8 mile trap speed and 1/4 mile trap speed.

My formula on motor would pick up about 26-27mph on motor and 34-35 on spray, grated it is a 6 speed car and the suspension setup was not that great ( mid 1.5's on or off the bottle)

 

Oh ok lol. That was a term i never heard before. Thanks

 

Figured we would update you guys, with nothing but a gear change we had some huge imporvements. We swapped out the 4.10 for some 3.73 and picked 9 mph, so now we backhalf about 31. we also logged the run and converter is just about perfect, 1000 rpm drop at 6600 shifts. It seems with the calculations it traps 6600 with either gear, so something is up, the map shows we have air, i think our issue is too low timing, i think its time to turn it up. 150mph stock cube nitrous ls1 here we come!

 

Oh and we got to weigh the car, unfortunately the th400 sns 12 bokt were more then we thought. Were right at 3400

 

about the same here, both NA and on the bottle.
