Yes, I plan on locking it up in 2nd gear.

Boy you better have a second kit for when you lock that baby up because it is going to pulllllllll the motor down when it does lock. Sounds neat though.

By second kit, do you mean second stage of nitrous?

Fbodyjunkie06

Yes, you're going to need to pour the power too it when it does lock up. When it does it doesn't allow the converter to slip anymore, and slip is what puts your converter in the rpm range it is supposed to be in (controlled slip that is). When you lock it up it pulls the motor down out of it's peak power band and you need more power to overcome that to bring it back into it's powerband.

I would be willing to bet if you don't pour more power to it when it locks that if you did a back to back run identically and not locking it, that it would e.t. better with it un-locked, but it will mph better with it locked.

Locking it gets rid of the slip which essentially makes it direct drive like a manual transmission does at all times.

If I were you I wouldn't lock it till 3rd gear right before the 1000' mark. The pro mod cars that utilize this same tech with the ATI superglide 5 usually lock theirs around 800-1000' and from what I have read the nitrous pro mods that use this have a small nitrous stage on top of their other stages that activates when it locks up to keep it from dragging it out it's power band.

The car does have 2 direct port kits. The second kit is for after the lock-up kicks in. The guy helping me build my car and tune it had a 01 SS and has a best time of less then 8.50 in the 1/4 with almost the same setup, but he had a 408 motor.

Sounds like you already had it planned out right then.

Very interested to see this applied in a street/strip car as I've only ever seen diesel trucks and pro mods use this while drag racing.

As soon as I get back home from Saudi Arabia on vacation in October, I plan on seeing what numbers I can put down. It just sucks right now seeing everyone else posting up there numbers and I can't put anything up, lol. But it will all be well worth it I hope come October.

Anyone else actually think the car will run 8's?

Anyone?

Does my vote count twice?

josh2002-ws6

Sure it does!!! LOL. I was just hoping that a few more people would agree and make me think that it is really possible.

I think your combo sounds swell, I'd give you my eye teeth and my appendix for a ride like it.

For a solid roller I think the duration is a tad bit on the low side. Big lift numbers, if the spring can control the lifter and you can make the car run hard in the front half, I think you can run in the 8s.
Hell it'll probably be faster than what I built for Whiteltone.

I had the same guy build the heads that spec'ed the cam and that was what he recommended. He also thinks I should only spin the motor to 76-7800 rpm's. I really hope it runs hard and hooks in the front half and lays down a high 8. I think I might need to switch from the 4.11 gear to a 3.90 or 3.73 since all I run is 1/4 mile. What do you think?

Fbodyjunkie06

iTrader: (10)

If all you run is 1/4 mile 3.73's.
3.73's will also benefit you in the traction department too. There will not be as much mechanical leverage/gearing with 3.73's versus your 4.11's.

The 4.11's would work on motor, but not on nitrous.

josh2002-ws6

What about the lock-up? Will that have any play in how the gear ratio plays out?

Fbodyjunkie06

iTrader: (10)

Didn't think about that, yes it will have a huge effect.

I might just keep the 4.11's then.

I just dunno about parts holding up with the converter locked like that. Not saying it won't work or doubting you, your buddy or what you would like, it just worries me about putting a lot of strain on the motor, trans, converter etc.

josh2002-ws6

I am not worried about anything in the drive line have problems with locking the converter up. The transmission was built to handle well over 2000 hp and the rear is a 9" 35 spline full spool with a steel drive shaft. The converter was custom built as a 5 disk from Precision. I think everything will hold together just fine. But I will find out come the end of September.

StrokerTA

If you wanna go thru the traps at 7600ish, I would keep the 4:11 gear in it. At 150mph that should be around 7500ish with a 28" tire and a 4:10/11 gear.
We put a 3.90 in whiteltone's car, I don't want that motor going thru the traps at 7500+ all the time though. Especially if we put the big boy jets in, we went thru at about 7,100 going 150 with the 200 jets..

I've seen it done all the time in Diesel trucks at the strip, but then again I here those same guys say all the time...damn transmission broke again and they have 5-6-7 thousand dollar transmissions in those things. Granted they are 8000lb trucks with 1000ft. lbs of torque at 1500rpm.

I am interested to see it run. ATI has a lock-up converter that works with their superglide 5 now. Works very well in pro-mod and ADRL cars and Top Sportsman cars I have seen it on.
