My original goals with the car have been way surpassed which was to run high 10's.

Goals and achievements:
2004 12.xx@118.5, aquire turbo v8
2005 11.73@124.7, 6 spd, 67mm turbo, drive the car, intercool it, install Th400
2006 10.87@125.9, forged motor, 76mm turbo, goal was high 10's
2007 10.13@132.7, 76mm turbo started the year at 11.0's goal was mid 10's
2008 10.15@136.6, 80mm turbo goal is high 9's

I feel like I'm starting to get greedy with what I my car to do. I'm after a car that is very streetable that can run a high 9 sec pass with a th400. I'm pretty happy with the cars setup right now and the way it drives, but I want a few 9 sec passes now that I'm so close. My car consistantly runs in the 10.1-10.4 range on 1.60-1.75 60's at 134-137 mph. It seems like my 9 sec pass is just a 1.50 60' away. The car is already pretty bad *** and can pull liter bikes on the freeway and from a dig at the track. I'm trying to avoid the mod that broke the camels back and makes me not like the car any more. Am I asking too much?


I'm switching out converters to try and find the ET by getting the car to spool faster off the line since my current one is too tight. I decided to go with a PTC converter spec'd out by Dusty Bradford. I've heard great things about the converters he specs out so I'm giving it shot to see how it works.

The last few thenths of ET are the most expensive

I don't see it as greed. I see it as ambition. Go for the 9 second goal.

I say go for it. As long as your still having fun with the car thats all that matters.

O and I think a little 50 shot of juice would get you that .15

y not go with a 3200-3600 5 disk vig stall that should put you in the 9's and still be great on the street

It's not greed it's the nature of the beast. Getting into racing puts you on a quest to always go faster. You don't think the guys running 7's are on a quest for 6's?

High 9's always sounds better than low 10's, you are asking the wrong crowd. Of course you need to push it some more.

I'm running a PTC converter and have not done anything really notable in my car for the last year or more, but the converters are highly regarded.

60ft is a formula that is partly based on the actual power you make, how well you utilize that power, and how well you hook that power. You make 9 second power but the car is dead hooking on all passes you are not coming out on enough power which can mean you need more converter.

So up the boost another pound or two and you are already at 9s.or a bit more timing..bit leaner afr..or throw on a 50 shot of spray maybe..Heck you could just do some weight reduction and be high nines ..
a arms, lighter kmember,some crome moly suspension stuff..You are so close now its not funny. What about electric cutout..cheap and fun mod.

This is a turbo car, for best results you have a converter custom made. Besides, isn't a 5 disk vig for a lockup 4l60e trans? My current vig works ok, but it's too tight IMO oppinion, Marty Chance and Dusty Bradford both think it's on the tight side as well.


PSJ, I feel that the converter is what is holding me back as well. My best 60' of this year is a 1.60 on 28" et streets. I watched a video of my car leaving and it seems to double weight transfer. first on the hit, then about 50' later when the gate opens it transfers again and then takes off. Spool is slow after the initial launch and it's very hard to hook a 10-11psi launch for fast spool, it's a VERY fine line. What i'm after is a converter that will let me launch on 5-6psi and then bring the boost in quick once the tires are already planted. My current converter did just that on the T76 with a 7-9psi launch, but with the turbo change it seems a bit too tight. The gate use to open about 20' after the launch on the T76. I'm running the same times on the ST80 with 2-3psi less boost and .1-.15 slower 60's.

I know its beside the point, but go pretty much anywhere else (reasonable altitude) in the US and you'd be in the 9s...

Get that converter to work well with the 28s, restall it or whatever you have to do. Also might try some suspension stuff and get that 60' down - low 1.5s/high 1.4s and you'd see a 9.999 for sure.

you dont need to change a thing but where you race.
drive up to cali, click off a mid 9 second pass, go to Disneyland to celebrate like you won the superbowl and drive home.

BRO, You're are trippin. Your car has 9s in it ALLLLL DAYYYYY. Like already mentioned, run at Famoso in Bakersfield and you're there.......or just work on getting your 60' down and you're WAYYYY in the 9s. Shave 2/10s off that 60 and you're runnin 9.80 or better. That's not greed, its just that your car is past the point where every mod just helps you go faster. NOW its a matter of the right mod and right settings (suspension, tire pressure, converter) on your combo......plus seat time.

I agree it should have 9's, but they keep hiding from me, just like the 10's did for a few months. I have stopped modding the car for the most part and am trying to make the overall car better at the reccomendation of my friend Jon (1320). I now have the power but I need to utilize it better. Suspension is on the list for next year. If I start pulling 1.4x-1.55 60's i'm in the 9's. At this point I think the converter has more effect than the suspension does so I'm putting my money into it first. I'm also going to do a tubular k-member/control arm setup next year to take some weight off the front.

I've never run at any other track besides Vegas, I don't have a truck or trailer and will not risk getting stranded, so I have to run 9's in Vegas. It doesn't count unless I do it here.

Wait about 3 weeks til the Street car supernationals come to town and go to their test and tune at night. They prep the hell out of the track in Vegas for the SCSN... Or use a little nitrous on the trans brake.
