You're in the WBP area or further south?

EDIT: Time to change that "10 second club" to "8 second club"!!
I live about 30 min from the track in WPB.

Yeah, I haven't had much luck getting that title changed in the past.

how are you keeping the wheelies under control? they seem very tame for an 8 sec et, turbo or not.

Th350 w/ RMVB and Transbrake - Built by Doug's Transmissions built 6/2007. Has Red clutches and JW HD intermediate sprag/drum assembly and the B&E Tbrake & Vbody. Everything else is stock. This transmission has seen more wheel stands than I can count. It has far exceeded any expectations that I had for it. It's about time for a glide.

FTI Torque Converter - Purchased at the same time as the transmission. It has been thru several different motor configurations. Greg at FTI is the The Man. He has restalled it several times and it's due for another restall. He takes great care of me as I have helped him corner the converter market in this area. It is stalling to about 5200 RPM which is ok but the shift extension is only at about 400 rpm. Definetly a couple MPH left in the converter.

2 Step - Lingenfelter LNC-003 set at 3600 RPM. Builds about 6-7 psi on launch. No timing modifications currently in use.

Boost Controller - AMS500 with CO2. 10# of CO2 on the gate at launch ramped over 4 tenths to 31# at full (19#) boost. I think that the fact that I need 31# on the back of the gate to build 19# of boost tells me that I have too much back pressure. I think that I would benefit from a larger backhousing.

Fuel - 93 octane up to 15 psi. For these passes I was on Maximal 116. It's mostly for some peace of mind. No meth. 17* of timing.

Suspension Front - QA1 "R" front shocks and the 275 springs. BMR Turbo Kmember, stock A Arms and no sway bar.

Suspension Rear - Jegster adj lower control arms, Jegster adj torque arm, BMR adj panhard, Eibach stiff springs, Comp Engineering 3 way adjustables in the rear and a S60 rear with 3.54:1 gears and a TruTrac.

Tires - Mickey Thompson 325/50/15's Drag Radials at 19psi (I think). Been a while since I checked the tire pressure.

Safety Equipment - Lap belt and helmet. This is one of the things that I am changing. The track is lax but not this lax. I get special treatment but they break my ***** every chance that they get. I am going to do a roll bar to start and see how it goes.




Standard ARP studs and stock 6.0 head gaskets with the AFR225 heads.

FAST90 and NW90 throttle body for induction.
So no pushing water ?
Nice to see fast 90 going to 20psi .So much for the naysayers. Did you do anything special to yours?
We have identical rearend . Was a bit worried tru track might not handle it versus spool or locker but would think being auto would help a lot . How many passes on the s60 ?

I figured out that the secret is in the ramp from launch boost to target boost. Car never went up all day. 4 tenths seems to be the magic number for me. One tenth faster ramp and it's on the bumper. The gears helped also but it'll still go up w/o the delay.

That's about perfect!

Haven't pushed any water yet.
The fast90 is a little modified. I cut off all the nipples and drilled a tapped the ports. Everything screws in. Also, I took it apart, removed all the gaskets in the channels between the layers and filled them with rtv.
The rear was one of my first mods. Started out with the 6 speed and 4.11s. Then I switched to auto and 3.73 and now running a 3.54 gear. The trutrac in the s60 is bigger and stronger than one for say s 9in rear. 35 spline axles vs 31 spline. You won't break it and it doesn't make clunking noise like a locker. Superb drivability. Only down side is that 3.54 is the closest ratio that you can go so if I want more mph, I'm going to have to spin it higher.

Yeah thought it should be pretty tough. So can you say how many passes you got on it? Was a bit worried but at worst was thinking to maybe get a wavertrac if they offer one but if it don't break for you it won't be breaking for me.

Yeah, what's up with that!

Nice runs. +1 on the converter. 400 RPM drop indicates it is a little too loose. Nailing the converter on mine was a big part of my performance.

Sadly, the A/C had to go in order to keep the front mount truck manifold kit simple. I do miss it and I may add a more compact aftermarket system down the road but it's a ways off. Might move up higher on the list once summer gets here. Never can tell.

Honestly, I couldn't tell you. Over 100 1.3X 60' passes for sure though. 3yrs +.
