That sounds about right. What stall are you running? 3400 is a decent raceweight, if you could do any mods to lighten up the hotrod some more it would help. Everything on mine is light weight, from the battery to the suspension to the interior, light weight carpet etc. If you can go from 3400 to 3300 your talking about a whole tenth in the 1/4 mile. It might make the difference from an 11.00 to a 10.90 run etc.

Nytmare: I always refer to race weight as the weight with me in the car on the scale at the track. I always go by the weight of the car as it goes down the track.

Yes that is why it is raceweight.
Raceweight includes everything right down to the 30 lb nitrous boddle some of us use.

BTW when my car was as heavy as a pig, weighing just over 3500 lbs and I add a extra 200 I ran 10.7's at 129-130 and only dynoed 525 running a little juice.
Also while only making 360 RWHP all motor I went 11.7.
This is with a 3600 Yank and 4L60E.

JS,
Sounds like I'm right with you - I'm at 3,600 headed for a minimum of 3475 when I finish my weight mods. I was hoping for 10's on motor too, but don't think I'm gonna make it. We are going to try another converter soon to get my 60's in the 1.4's, but I don't think I'm gonna make it without porting my heads.

I decided I'm not gonna spend any more money (after the weight mods) to try and make it on motor - if I don't get it this fall, I'll break out the bottle.

I have a 396 stroker, every suspension mod you can get, just put a TH400 in it, transbrake, the whole 9 yards. still cant break into the 10s.

Whats your race weight?

770Guy

3500lbs

Coach 02 A3 Z/28

Something is not right with your set up. At 3500 lbs you should be in the 10's no problem.

Give us more info on your set up Please.

3520lbs here, last dyno was 441rwhp unlocked, ran a 10.96 @ 124 (1.54) at ~300' DA.

With a 50 dry shot shutting it off at 5900rpm and shifting at 6500 I ran 10.74 @ 125 at 2000' DA

770Guy

60ft is 1.39 , 1/8th is 7.15 @ 95 , the last run in the 1/4 was 11.15ish, but we ran out of gear about 20 feet before the traps, just went down to a 4.10 gear from a 4.30. This weekend ill have new quarter times, if it doesnt break 10s we are gonna be disapointed.

770Guy

This is the setup as it was when we were strugglin for low 11s. We just added a spool with 4.10s and the Strange Lightweight brakes, and 1 lightweight non adjustable racing seat.

Setup is as follows:

!ac
!front sway bar

396 Stroker
Strange 12 bolt 4.30s (now a spool with 4.10s)
TCI TH400 B&M Ratchet Shifter
TCI4400Stall
Transbrake
BMR 32mm Drag sway bar
BMR Xtreme Duty Torque Arm
BMR Adjustable tubular Lower Control Arms
BMR Lightweight K-member
QA1 shocks (front and back)
BMR adjustable Panhard Rod
Bogarts with 28.5 Hoosiers out back and skinnies up front
BMR subframe connectors

I think thats about it, probably something I left out.

A 1.39 60ft and you ran a 7.15 @ 95 mph. I cut high 1.4's and run 6.90's at 98 mph with a stock LS1 motor with the T-Rex cam. Something seems to be wrong with your set up. With the 4.30 gears I would say that you need a 29.5 to a 30 inch tire so you don't hit the rev limiter. You will be better off with the 4.10's and the 28 inch tall slicks.

What is your rev limiter set at?
What rpm are you shifting at?
What rpm are you leaving off the tranz-brake?

Coach

770Guy

Limiter is set at 7,000
shifting at 6800
leaving at around 5000 with tranzbrake

770Guy

And about the 60 foot thing, thats what me and my dad have been trying to figure out. How in the hell can we be pullin 1.39 60 foot times and still not be gettin atleast 6.90s in the 1/8th. I dunno if you saw my post in the Dyno section or not, but with the 6speed we made 504 and after we put the TH400 in we only made 420rwhp so we lost 84rwhp with the TH400, but gained about 40 rwtq

Coach 02 A3 Z/28

More info on the convert/trans set up please. We need to help ya figure this out, brother. My Dad and I have been right where you are. If I can help, let me know.

Coach

770Guy

I dont know all the details, Ill have to ask my dad when he calls. We are running out of gear so thats probably why we arent in the 10s, but the 1/8th mile times make no sense at all. TCI told us the only thing they could suspect is that they sent the wrong converter and asked us to take it out and send it to them.

Coach 02 A3 Z/28

iTrader: (10)

IMO, Running out of gear in the 1/4 didn't hurt the 1/8 mile times. I have alot of 1/8 mile data and Even when I was running 11.20's in the 1/4, I ran high 7.0's to very low 7.teens in the 1/8.

We need to know about the convert and trans set up to help ya out.

Coach

770Guy

What exactly do you need to know about the tranny and converter? All I know off the top of my head is its at 4400TCi converter and a TCI TH400
