what are you guys gaining with a 100 shot? once i figure out my high end miss im going to be putting the bottle back on.

what im trying to figure out what i need to do about gear/tires, right now im running 4.30s with 26. 11.5 15 hoosiers. i got to pull the rear end soon, and i have a set of 3.70s i could put in, but rather get the extra mph from tire size and not gear change.

 

Whats your RPM limit? Does your car make power to like 65-6700 RPMs? That would be handy to know. Your setup looks pretty similar to Kryckter's old car. His ET and MPH is about the same as yours. I believe he had some issues when he started spraying but I think he did like 128 on the 150 shot. So I would say mid 120's is where you would be on a 100 shot. I would imagine that you have the RPM capability to run to 7000 for the traps since your are already running a 4.30 gear. My calculations lead me to think if ya kept the 26" tire, and went through the traps @ 125 you would be at 7000. If you want your RPM's lower through the traps, or want more MPH capability you can just throw some 28" tires on. I don't think you will want 3.70's with a setup like yours.

EDIT: I see your running a stock bottom end, maybe I was too quick to assume your car makes power that high, or that you wanna rev that high. If so please correct me.

 

7k might be pushing it, i have no issue spinning it to 6500 though.
if im only trapping around 125-127 i should be fine with a 28 inch tire and the 4.30s

yeah the 3.70s will really kill my n/a times.

 

Yeah, I think your correct. I think the 4.30's are perfect for your setup. The 28" tire might help with your 60ft as well. If anything, you may just have to go through the traps 1-200RPM's higher than you would like.

I think the 3.70's would kill your N/A times as well. I think I would rather be alittle overgeared than undergeared.

 

so will that extra torque from the nitrous.




thanks for the help.

 

What about me? 4.10s 7200rpm limiter, bogging off the line it ran an 11.7@118. What will the 150,200,250, and 300 put me at with the direct port setup i am getting? Assuming i can hook it up.

 

faster ..... fastest........ and get the hell out of the way.........

 

guy here ran something like a 13.4 NA, then with his 300 shot he was down in the mid 10s but that was a 383 with a KILLER nitrous grind cam

edit: but i dont know MPHs...

 

Think i will break 130-135?

 

I run 11.6@ ~118mph na and 10.39@130mph on a 250 shot custom LE cam on a 110ls. 3600lb race weight.

The third calculator down lets you play with tire size and calculates effective gear ratio.

 

I would think on a 200 if your spraying of the line you would trap somewhere between 130-135...and def more on a 300 shot.

 

I guess i can always slow down if i approach the 135 mark,no full cage or shoot for mr

 

Hey blkchevyz care to get a little more info on your setup? cam specs? exhaust, etc.

 

stock bottom end, all the bolt ons, chs head, cam is a fms custom grind, its around 233 243 600 600 112

the heads are what got me over the 400 hp mark, gain 20 hp from them over my previously ported lt1(ARE)
