The only way your going to get deacent 60ft in a NV5600 is doing a boosted 3rd gear launch. Simply reving it up and dumping it at 3psi isnt going to work.

You need to get a line lock and a DD clutch.

Slip your new DD at the line to build boost 10-20psi and then you will turn some good 60ft.

Your stock clutch isnt going to hold the new power from a turbo and improved electronics.

What are you thinking????? Your talking about adding nitrous to a pretty much stock truck so you can shave 2/3 of a second off your ET

Get some supporting mods that will make your truck live a much longer happier life because your going down a road thats going to hurt your truck.

Spend your $$$ wisely

 

I agree with slowsixspeed. At this point nitrous is not the way to go.

 

Most of the information I have compiled from this site and others have shown there is not a "huge" improvement over a 3rd gear launch compared to what I am running. Most are getting 1.75-1.85 tops. I have a lot of wheel spin at the line and I am going to get some traction compound and soak some into the rubber.The EGT's are well within limits at the end of a quarter mile but I have just tapped the exhaust manifold to check drive pressure. The NOS would be used to light the turbo at the line and if during testing I find the drive pressures get too high I will put a pressure switch in to kick it out at 20-25 psi. If I thought a bigger turbo would make a difference, I would be on the phone to HTT tomorrow. I have a pyro before and after the turbo because I cant figure out why everyone is having high egt's with stock turbos. Remember, I might be pushing 475hp on a great day to the back tires and I have been running pretty respectable times. The clutch is the strongest single disc I could find. I have a fine collection of Con FE's, Sintered Iron, Kevlar discs in the basement. I have driven trucks with double disc clutches and it makes a huge difference on shifting, although I have not tried a Haisley strip clutch yet. I was mostly looking for hard facts here but most serious drag racers here run autos. I am not sure what supporting mods you are in reference to. My rail pressure stays 22-24k, CP3 fed 28psi, open exhaust , bigger CAC etc. But hey, everyone has a opinion

 

Your truck is fine if you keep it for intended pourpose but if still feel the need for more speed then there's going to be alot more on your plate.

I'm talking and this threads should be titled 3rd gear BOOSTED launch times.

Boosted launches is how autos have advantage.

Have you even been in a 500hp CTD doing a 4x4 20psi boosted launch????

Well it is like being on a launch pad....

Simply dumping the clutch in 3rd gear is like an auto not doing a boosted launch, and they dont do that.

What you need is a simple $80 line lock from Summit Racing and a DD thats rated for it.

Lock your tires with the lock and then rev the engine and slowly let the clutch out until it starts slipping and building boost until 20psi or so and the release all the brakes and hold on because you just turned a 1.8 60ft.

This is key if you really want to drag race your manual.....

As you are now learning autos rule at the drags and ther wifes can still drive them around town which is kinds hard if you have a 3850 DD.

 

After reading this thread, I had to try the 3rd gear launch. Did it last night in 3rd, 4x4. Dont know how much boost I built but I used the 3 foot method. It did not bog the engine down or spin any tires. It did feel like it would have been a little quicker on a timed run.

That was the whole purpose of this thread. 1.8's are usualy what double disc clutches are turning. I am now 1/10 of a sec. off of that. I will give 1/10 for the faster shifting clutch. If you put race tires in the equation it is a different story. Anyway it is pointless to stay here and argue about what it could or might do. As soon as we get a decent cold snap here, I will know what it will do.

 

How do you like your Haisley? I heard they are the fastest double you can get. Did you get the 6 puck or 12? I want to get one to try but I dont know if I want a 6 or 12 button set up.

 

Looking at your slip....I would say you just need too work on the first 1/8. Your gaining 23 mph in the 2nd 1/8th.....which is the norm for most trucks in the 12-14 sec range....but a 77mph trap in the first 1/8th is about 5 mph slower than it should be for these times.

 

Im not 100% positive but picking up 1/10th in the 60ft can result in cutting 3/10 in the 1/4.

That 1.8 was just a guess and im betting you could be even quicker.

Heck I was cutting 1.9's on my stock + EZ on my 02HO

 

I like the clutch alot. Im not running crazy power, but ive yet to slip it. It also shifts as fast as I can slam the shifter around. I have the 6 button street drag.

 

I think I will pick up a lot more time by going on Saturdays and running at test and tune. I have 2 seasons on the car in the Friday Street class and a total of 14 passes on the truck. I still get butterflies and nervous at the line and I spend too much time looking in the other lane. I need a set of Amish horse blinders and some DTR stickers.... then I will get those 4 tenths I am looking for.

 

A $80 line lock will also help out alot. If your track is like mine I still roll a little once im staged and both of my feet are too busy with the clutch and throttle.

Ive red lighted a few time because of the roll.
